技术领域technical field
本发明涉及医疗系统。更具体地，本发明涉及麻醉系统，其具有集成、可展开临床中心和临床医生/麻醉师办公室。The present invention relates to medical systems. More specifically, the present invention relates to an anesthesia system with an integrated, deployable clinical center and clinician/anesthetist office.
背景技术Background technique
麻醉师花费很多时间在要求其警惕，这些在较直接的病例中，但很少是直接临床处理。他们通常被要求进行多种文字工作和文件工作而仅有一张麻醉系统桌面作为工作表面。此外，通常没有用于他们的文件、文档和个人物品，如手机、钥匙、电脑、眼镜、皮夹、钱包等的存储区域。另外，常规麻醉系统的临床使用区域没有提供用于注射器、喉镜和其它临床设备的便利位置。麻醉系统的常规设计不具有分离的临床和办公室功能。大多数系统仅为麻醉师体供不大的空间来进行其工作，且该空间需与药物和器具的临床准备空间共用。Anesthesiologists spend a lot of time calling their vigilance, in more immediate cases, but rarely in direct clinical management. They are often required to perform multiple paperwork and paperwork with only an anesthesia system desktop as a work surface. Also, there is often no storage area for their files, documents and personal items such as cell phones, keys, computers, glasses, wallets, wallets, etc. Additionally, clinical use areas of conventional anesthesia systems do not provide convenient locations for syringes, laryngoscopes, and other clinical equipment. Conventional designs of anesthesia systems do not have separate clinical and office functions. Most systems provide only a small amount of space for the anesthetist to perform his work, and this space needs to be shared with the clinical preparation space for medications and instruments.
此外，大多数当前的麻醉系统设计没有为呼吸回路连接提供铰接部(articulation)，其用于为患者提供更近的呼吸和传感器连接。由于大多数当前的呼吸系统设计完全地集成至麻醉系统中，因此必须将整个系统带至非常接近患者以进入必须的临床控制而同时照顾患者和他们的气道。在手术室(OR)中的物理限制是由于但不限于手术类型，OR布局，使用中的设备，室中需要的人员数量，人员位置，以及其它原因，这增加了对麻醉系统的定位和结构的需要，特别是涉及呼吸管口连接。呼吸管口连接通常限制系统的移动，且如果在错误的方向上扭曲或转动，则存在断开的风险。该物理结构带动了对非常小的覆盖区系统的需要，其还限制了麻醉师工作可用的空间。Furthermore, most current anesthesia system designs do not provide articulations for breathing circuit connections, which are used to provide closer breathing and sensor connections to the patient. Since most current respiratory system designs are fully integrated into the anesthesia system, the entire system must be brought very close to the patient to gain the necessary clinical control while caring for the patient and their airway. Physical constraints in the operating room (OR) due to, but not limited to, the type of surgery, OR layout, equipment in use, number of personnel required in the room, personnel location, and other reasons add to the positioning and configuration of the anesthesia system needs, especially when it comes to breathing tube connections. Breathing tube connections typically limit movement of the system and risk disconnection if twisted or turned in the wrong direction. This physical structure drives the need for a very small footprint system, which also limits the space available for the anesthetist to work.
尽管一些常规的现有技术麻醉系统允许呼吸回路从系统铰接离开，并被设置在非常接近患者处，然而这些系统的大多数临床控制位于系统的主本体上，因此使得使用起来很笨重。While some conventional prior art anesthesia systems allow the breathing circuit to be hinged away from the system and placed in close proximity to the patient, most of the clinical controls for these systems are located on the main body of the system, thus making them cumbersome to use.
例如，普通的常规麻醉系统使用在双铰接管状臂上的呼吸回路，该双铰接管状臂可从麻醉系统台车移开。这要求将软管从呼吸系统垂至台车，所述软管包括新鲜气体软管、呼吸机驱动气体和清除气体-都具有泄露和断开的可能性。此外，该系统中的换气、新鲜气体流(FGF)和蒸发器控制都设置在台车的背后，且远离用户与患者的直接临床交互。其缺点在于需要用户时常地从患者转开，以观察监测或者进行调节。此外，在伸展位置时，管状臂容易被从床、人员等施加的过大的力损坏。For example, common conventional anesthesia systems use a breathing circuit on a double articulated tubular arm that is removable from the anesthesia system cart. This requires slinging the hoses from the breathing system to the dolly, including the fresh gas hose, ventilator drive gas and purge gas - all with the potential to leak and disconnect. Furthermore, the ventilation, fresh gas flow (FGF) and vaporizer controls in this system are located on the back of the trolley, away from the user's direct clinical interaction with the patient. This has the disadvantage of requiring the user to turn away from the patient from time to time to observe the monitoring or make adjustments. Furthermore, when in the extended position, the tubular arms are easily damaged by excessive force applied from a bed, person, or the like.
一些新的常规麻醉系统将呼吸回路和控制装置固定在台车框架上，要求用户将整个系统带至接近患者。这迫使减小系统尺寸，从而减小了麻醉师可用的“工作空间”。此外，麻醉师的用于文件和存储的工作区域也被带至接近患者和临床区域，这在临床和空间管理角度是不理想的。在可选的方式中，用户可将系统设置成离患者更远，但接着必须经常从患者来回以观察监测并进行设置改变。Some newer conventional anesthesia systems have the breathing circuit and controls fixed to the trolley frame, requiring the user to bring the entire system close to the patient. This forces a reduction in system size, thereby reducing the "workspace" available to the anesthesiologist. In addition, the anesthesiologist's work area for documentation and storage is also brought close to the patient and clinical areas, which is not ideal from a clinical and space management standpoint. In an alternative, the user can set the system further away from the patient, but then must frequently travel back and forth from the patient to observe monitoring and make setting changes.
因此，当前可用的麻醉系统没有提供现代的麻醉师所要求的必要存储区域、类型或连通性。这包括电源连接和个人电子产品的存储，例如计算机、个人数字助理(PDAs)、数据/移动电话装置、个人音乐装置、无线耳机等等。考虑到很多麻醉师在他们所工作的医院中不具有办公室，所以需要满足麻醉系统的用户用于进行包括案例文件整理等日常活动的改进的装置。一些要求诸如胶带分配器、衬里垃圾桶和文件存储区域等的特征通常在办公室环境中存在，但是仍然没有被集成至当前的麻醉系统中。Accordingly, currently available anesthesia systems do not provide the necessary storage area, type or connectivity required by modern anesthesiologists. This includes power connections and storage for personal electronic products such as computers, personal digital assistants (PDAs), data/mobile phone devices, personal music devices, wireless headsets, and the like. Given that many anesthesiologists do not have offices in the hospitals in which they work, there is a need for an improved device for users of anesthesia systems to perform daily activities including case filing. Some required features such as tape dispensers, lined trash cans, and document storage areas are commonly found in office environments, but are still not integrated into current anesthesia systems.
因此，需要一种麻醉系统，其具有分离的临床和办公室功能。还需要麻醉系统，其允许系统的一部分被移动至接近患者，使得可进行临床控制且同时照顾患者的气道，而不牺牲临床医生可用的办公空间或者挤占患者的区域。此外，麻醉系统在呼吸管的连接处需要改进的挠性以增加定位选择。Therefore, there is a need for an anesthesia system that has separate clinical and office functions. There is also a need for an anesthesia system that allows a portion of the system to be moved close to the patient so that clinical control can be done while taking care of the patient's airway without sacrificing office space available to the clinician or crowding out the patient's area. Additionally, anesthesia systems require improved flexibility at the connection of the breathing tube to increase positioning options.
另外，常规的麻醉系统被设置有报警，其被设计成提醒用户系统工作中发生的潜在技术问题。这些报警通常是短的文字串，其占用麻醉系统上设置的显示屏的显示器的有限空间，且因此不能提供说明引起报警的技术问题的详细信息。此外，这些报警字串可能被要求翻译为不同的本地语言，该本地语言可能无法像设计者在英语中预想的那样清楚明了地反映错误。一些现有技术的产品设计包括将额外的说明文字或图像表示显示在显示屏上，说明报警所反映的潜在的问题。然而，这要求临床用户将更多的注意力集中在阅读或试图将图像与他们所使用的实际系统联系起来。通常，在医疗紧急情况过程中发生的麻醉系统的报警对用户造成混淆和紧张情况。此外，很多用户对系统功能的复杂细节不熟悉，且不能够将报警信息与必要的修正动作容易地联系起来。另外，很多用户使用多个制造商的系统，其可能使用相同的或者相似的报警信息以确定不同的设备故障、问题或行为。此外，用于报警信息的缩短的文字串和/或翻译没有表示充分的信息以足够让用户诊断问题。因此，要求改进的报警显示器系统。In addition, conventional anesthesia systems are provided with alarms designed to alert the user of potential technical problems in the operation of the system. These alarms are usually short text strings which take up limited space on the display of the display screen provided on the anesthesia system and therefore do not provide detailed information explaining the technical problem that caused the alarm. Additionally, these warning strings may be required to be translated into a different local language, which may not reflect errors as clearly and clearly as the designers intended in English. Some prior art product designs include displaying additional explanatory text or graphic representations on the display screen to illustrate potential problems reflected by the alarm. However, this requires clinical users to focus more on reading or trying to relate the images to the actual system they are using. Often, the alarming of the anesthesia system that occurs during a medical emergency creates confusion and a stressful situation for the user. Furthermore, many users are unfamiliar with the intricate details of system functionality and are not able to easily correlate alarm messages with necessary corrective actions. Additionally, many users use multiple manufacturers' systems, which may use the same or similar alarm messages to identify different equipment failures, problems, or behaviors. Furthermore, shortened text strings and/or translations for alert messages do not represent sufficient information for a user to diagnose the problem. Accordingly, an improved warning display system is desired.
一些常规的麻醉器当前被装配有“报警静音”按钮，可将其按压以将系统报警功能的声音部分静音最多两分钟的一段时间。该功能确保报警是具体已知的且被用户直接静音。然而，要求将报警静音按钮物理地按压对于手被护理患者占用的用户(例如，吸入、再插管、给予药物)来说是挫败的。因此，需要以非接触，但仍然可靠的方式将报警静音的方法。当用户被都关于同一情况或临床状况的一系列报警干扰时，这使特别需要的。例如，在患者的吸入过程中发出声音的报警，可在不同时间启动所有的低压报警、泄露报警、低分钟容量报警和低呼吸容量报警。Some conventional anesthesia machines are currently equipped with an "alarm silence" button which can be pressed to silence the audible portion of the system's alarm function for a period of up to two minutes. This feature ensures that alarms are specifically known and silenced directly by the user. However, the requirement to physically press the alarm mute button can be frustrating for users whose hands are occupied with caring for the patient (eg, inhaling, reintubating, administering medication). Therefore, there is a need for a method of silencing an alarm in a non-contact, yet reliable manner. This is particularly desirable when the user is disturbed by a series of alerts all relating to the same situation or clinical condition. For example, an audible alarm during a patient's inhalation can activate all low pressure alarms, leak alarms, low minute volume alarms and low respiratory volume alarms at different times.
另外，大多数常规的麻醉系统具有被称作“O2涌流(flush)”的功能。该流主要用于在出现或修整泄露并用于将麻醉制剂冲出循环系统时将风箱重新灌注。一旦为了灌注风箱的目的启动O2涌流，则风箱被灌注满不含有麻醉制剂的气体。因此，要求麻醉师再平衡回路中出现的麻醉制剂的量，以确保对患者的正确处理。因此，期望具有单个作用功能以提供与O2涌流相似的高流动性，同时使用的混合气体和麻醉制剂的水平已经被用户预定，以让风箱被预灌注同时保留了之前设定的气体混合和麻醉制剂水平。Additionally, most conventional anesthesia systems have a feature called "02 flush". This flow is primarily used to reprime the bellows in the event of a leak or repair and to flush the anesthetic agent out of the circulation. Once theO2 surge is initiated for the purpose of perfusing the bellows, the bellows are filled with gas that does not contain anesthetic agent. Therefore, the anesthesiologist is required to rebalance the amount of anesthetic agent present in the circuit to ensure proper treatment of the patient. Therefore, it is desirable to have a single action function to provide high flow rates similar toO2 surges, while the levels of gas mixture and anesthetic agent used have been predetermined by the user to allow the bellows to be pre-primed while retaining the previously set gas mix and Anesthetic agent levels.
如本领域已知的，具有电子混合控制的麻醉系统通常还包括紧急旁路阀系统，其使得用户能在混合器失效的情况下设置氧气流。一些现有技术的麻醉系统使用专用的针阀以提供旁路功能，而其它的使用专用的机械-气动开关以打开旁路阀或还原至电子混合器控制。As is known in the art, anesthesia systems with electronic mixing controls typically also include an emergency bypass valve system that allows the user to set the oxygen flow in the event of a mixer failure. Some prior art anesthesia systems use a dedicated needle valve to provide a bypass function, while others use a dedicated mechanical-pneumatic switch to open the bypass valve or revert to electronic mixer control.
精确监控输送至供氧患者的量和压力是非常重要的，特别是在具有肺并发症时。在患者的气道测量流动和压力与在麻醉器中测量这些参数相比提供了实质性的优点。当前的近程传感器使用气动或电连接回至麻醉系统。该连接在患者的气道处形成显著的体积和重量，其可引起患者的气管内导管的断开和物理拉紧。因此，很多用户将这看作近程传感器的显著缺点，且选择在接近麻醉系统的较不理想的位置进行患者监测和输送控制。此外，使用差压式流动传感器和近程气道压力传感器要求使用连接至麻醉系统的气管。这些管可以被在OR中移动的装置的轮扭结或者封闭，使得传感器通道中的数据丢失。气动管还可以是呼吸回路的气体泄露源，且其长度可导致由于气动信号传输、普通模式误差引起流动测量错误。因此，需要没有管或连接回至麻醉系统的用于近程设置的单个、小的传感器方案。Accurate monitoring of the volume and pressure delivered to oxygenated patients is very important, especially when there are pulmonary complications. Measuring flow and pressure in the patient's airway offers substantial advantages over measuring these parameters in the anesthesia machine. Current proximity sensors use pneumatic or electrical connections back to the anesthesia system. This connection creates significant bulk and weight at the patient's airway, which can cause disconnection and physical strain on the patient's endotracheal tube. Therefore, many users see this as a significant disadvantage of proximity sensors and choose to perform patient monitoring and delivery control in a less desirable location close to the anesthesia system. Additionally, the use of differential flow sensors and proximal airway pressure sensors requires the use of a trachea connected to the anesthesia system. These tubes can be kinked or blocked by the wheels of the device moving in the OR, causing loss of data in the sensor channel. Pneumatic tubing can also be a source of gas leakage for the breathing circuit and its length can lead to flow measurement errors due to pneumatic signal transmission, common mode errors. Therefore, there is a need for a single, small sensor solution for a proximal setting without tubing or connections back to the anesthesia system.
当前的麻醉蒸发器系统包括阀和/或芯系统，用于将液体麻醉制剂转换为气体形式。通常地，这些系统提供的气体的制剂浓度水平为0-10％(对于Suprane尽管有时更高)，该气体用作循环呼吸系统中的“新鲜气体”或“补偿”气体。当前的装置是非常复杂的，且要求精确的机械部件或流动控制系统进行操作，导致装置成本较高。在此通过引用结合受让给Louis Gibeck AB的专利号为6,155,255的美国专利的全部内容，其中提出“蒸发器，包括具有气体入口和气体出口的蒸发腔室，且其容纳被设置成将液体暴露至蒸发腔室以蒸发该液体的多孔液体输送装置，其中所述多孔液体输送装置连接至与外部液体源连通的液体供应装置，其中所述多孔液体输送装置被设置成仅通过所述多孔液体输送装置中的小孔而暴露所述液体；且其中所述液体供应装置包括液体量调节器”以及“蒸发液体的方法，包括以下步骤：从外部液体源将液体输送至液体输送装置；和将所述液体输送装置中的液体暴露至流动气体以将与气体接触的液体蒸发，包括，将所述液体引导至所述液体输送装置中的小孔，仅通过所述液体输送装置中的小孔将液体暴露至气体，以及调节输送至所述液体输送装置的液体的供应”。Current anesthetic vaporizer systems include valve and/or wick systems for converting liquid anesthetic agents into gaseous form. Typically, these systems provide a formulation concentration level of 0-10% (although sometimes higher for Suprane) with gas that is used as the "fresh gas" or "make-up" gas in the rebreathing system. Current devices are very complex and require precise mechanical components or flow control systems to operate, resulting in high device costs. U.S. Patent No. 6,155,255, assigned to Louis Gibeck AB in its entirety, is hereby incorporated by reference in its entirety, which proposes an "evaporator comprising an evaporation chamber having a gas inlet and a gas a porous liquid delivery device to the evaporation chamber to evaporate the liquid, wherein said porous liquid delivery device is connected to a liquid supply device in communication with an external source of liquid, wherein said porous liquid delivery device is configured to deliver only through said porous liquid delivery device an aperture in the device to expose the liquid; and wherein the liquid supply device includes a liquid volume regulator" and "a method of evaporating a liquid comprising the steps of: delivering liquid from an external liquid source to the liquid delivery device; and exposing the liquid in the liquid delivery device to a flowing gas to vaporize the liquid in contact with the gas, comprising, directing the liquid to a small hole in the liquid delivery device, only passing through the small hole in the liquid delivery device exposing the liquid to the gas, and regulating the supply of liquid to the liquid delivery device".
期望知道移动通过蒸发器的气体流的量，且具有测量所产生的可吸入气体中的麻醉剂浓度的直接装置。还期望精确地测量进入蒸发器的液体流的量，用于计算制剂浓度的目的。因此，需要将已知的蒸发器系统结合至麻醉系统。It would be desirable to know the amount of gas flow moving through the vaporizer, and to have a direct means of measuring the concentration of anesthetic in the resulting inhalable gas. It is also desirable to accurately measure the amount of liquid flow entering the vaporizer for purposes of calculating formulation concentration. Therefore, there is a need to incorporate known vaporizer systems into anesthesia systems.

图1C示出了本发明的麻醉系统的一个实施方式的后侧，示出了连接区域130，其中电连接至监测设备。此外，如上所述，图1C还示出了生理监测器132。Figure 1C shows the rear side of one embodiment of the anesthesia system of the present invention showing the connection area 130 where electrical connections are made to monitoring equipment. Additionally, Figure 1C also shows a physiological monitor 132, as described above.
图1D更详细地示出了呼吸(ventilation)监测参数连接区域119。此外，图1D还以放大图示出了麻醉气体清除系统156。且最终地，附图还示出用于呼吸气体监测器的示例连接界面163。Figure ID shows the ventilation monitoring parameter connection area 119 in more detail. In addition, FIG. 1D also shows an anesthetic gas scavenging system 156 in an enlarged view. And finally, the figures also show an example connection interface 163 for a respiratory gas monitor.
再参考图1A，可进行几种类型的移动以相对于本发明的麻醉系统的AO104定位CC102。首先，旋转移动可用于将呼吸回路150(或者CC 102)在接合197处以最大45度的增量式角度远离或朝向AO 104旋转，使得CC 102在相对于AO 104的第一伸展位置处。Referring again to FIG. 1A, several types of movement may be performed to position CC 102 relative to AO 104 of the anesthesia system of the present invention. First, rotational movement may be used to rotate breathing circuit 150 (or CC 102 ) away from or toward AO 104 at joint 197 in increments of up to 45 degrees such that CC 102 is in a first extended position relative to AO 104 .
在一个实施方式中，CC 102在设置于AO 104上的底座支架上的滑动轨道(未示出)上移动，从其在AO 104上的锁定位置(即，完全集成位置)移动至完全伸展位置。在一个实施方式中，轨道的一部分优选地被设置成与AO 104的正面和轮底座成倾斜的角度，其在一个实施方式中是24度，从而允许CC 102移动且其连接口从其完全集成位置向前和向左移动。In one embodiment, the CC 102 moves on sliding tracks (not shown) provided on a base bracket on the AO 104 from its locked position on the AO 104 (i.e., fully integrated position) to a fully extended position. . In one embodiment, a portion of the track is preferably set at an oblique angle to the front of the AO 104 and the wheel mounts, which in one embodiment is 24 degrees, allowing the CC 102 to move and its connection ports to fully integrate therefrom The position moves forward and to the left.
第二，在接合196处的平移运动具有0至14.5英寸的范围，以将CC 102压缩和折叠回AO 104中，或将CC 102从AO 104延伸离开。此外，在接合处196的平移运动还导致在接合处197的平移运动。因此，一旦从AO 104平移远离，CC 102处于相对于AO 104的第二伸展位置。Second, translational motion at joint 196 has a range of 0 to 14.5 inches to compress and fold CC 102 back into AO 104 or extend CC 102 away from AO 104 . Furthermore, translational movement at joint 196 also results in translational movement at joint 197 . Thus, once translated away from AO 104 , CC 102 is in a second extended position relative to AO 104 .
此外，上述旋转和平移运动可结合，使得CC 102位于相对于AO 104的第三伸展位置。Additionally, the rotational and translational movements described above may be combined such that CC 102 is in a third extended position relative to AO 104 .
对本领域技术人员来说很明显，尽管仅示出了少数的位置，然而CC 102相对于AO104具有多个位置。在一个实施方式中，可通过将CC 102从AO 104旋转、平移，或者旋转和平移离开而进入工作空间点(在图2A中以297示出，且在下文中更详细地说明)。It will be apparent to those skilled in the art that although only a few positions are shown, CC 102 has multiple positions relative to AO 104 . In one embodiment, the workspace point (shown at 297 in FIG. 2A and described in more detail below) may be entered by rotating, translating, or rotating and translating the CC 102 away from the AO 104 .
图2A示出了CC 202向外伸缩且从AO 204远离，形成用于临床医生使用的临床工作空间区域。通过比较，且再参考图1A，在图1A中示出的本发明的麻醉系统100是完全折叠位置。再参考图2A中的伸缩的系统200，在CC 202从AO 204移动远离时所形成的间隙扩张且露出工作表面210，使得其从主AO工作表面207下方的区域延伸出来。这些表面210在其接合面211具有紧公差或挠性密封，以避免位于表面上的材料被堵塞至表面之间的间隙中。在一个实施方式中，CC 202的移动被步进(indexed)以形成CC 202相对于AO 204的刚性定位装置。在其它实施方式中，还可使用不包括步进的多个其它锁定装置，以获得具有足够刚性的锁定机构，以防止CC 202相对于AO 204的无意的移动和将扩展的工作表面210上的物品移开。Figure 2A shows CC 202 telescoping outward and away from AO 204, forming a clinical workspace area for use by clinicians. By way of comparison, and referring again to FIG. 1A , the anesthesia system 100 of the present invention is shown in FIG. 1A in a fully collapsed position. Referring again to the telescoping system 200 in FIG. 2A , the gap formed when the CC 202 moves away from the AO 204 expands and exposes the working surface 210 such that it extends from the area below the main AO working surface 207 . These surfaces 210 have close tolerance or flexible seals at their interface 211 to avoid material lying on the surfaces from being jammed into the gaps between the surfaces. In one embodiment, the movement of the CC 202 is indexed to form a rigid positioning of the CC 202 relative to the AO 204 . In other embodiments, various other locking devices that do not include steps can also be used to obtain a locking mechanism that is sufficiently rigid to prevent inadvertent movement of the CC 202 relative to the AO 204 and the expansion of the working surface 210. Item moved.
在多个实施方式中，要求防止诸如废弃材料、笔、针、注射器等的杂物被拉入麻醉系统的内部、非用户接触部分。如果允许该杂物滑动至主AO 204工作表面207或者CC 202的工作表面210下方，则可引起收缩或者伸展堵塞，或者另外地干扰和妨碍麻醉系统的内部分。此外，重要的是在收缩/折叠过程中保证系统的部分移动至内部，如当收缩时在主AO204工作表面207下方移动的工作表面210，不会引起内部的微生物污染，其可以是可伸展工作表面210的再污染源，即使之前已经清洁过表面。In various embodiments, it is desirable to prevent debris such as waste materials, pens, needles, syringes, etc. from being drawn into the internal, non-user contacted parts of the anesthesia system. If allowed to slide beneath the main AO 204 working surface 207 or the CC 202 working surface 210, this debris could cause constriction or extension blockage, or otherwise interfere with and obstruct the internal parts of the anesthesia system. Also, it is important to ensure during the shrink/fold process that parts of the system that move to the interior, such as the work surface 210 that moves under the main AO 204 work surface 207 when shrinking, do not cause microbial contamination of the interior, which can be stretchable A source of recontamination of the surface 210, even if the surface has been previously cleaned.
如上所述，麻醉系统的从上方或下方移动经过彼此的表面，如表面210和207，在其接合面211具有紧公差或挠性密封，以避免位于表面上的材料被堵在间隙中或者卡在表面之间。在一个实施方式中，所使用的挠性密封件是“球缘密封条(bulb seals)”，如本领域技术人员已知的。在应用之后，当表面210收回或折叠进入系统时，该球缘型密封条弯曲以完全填充表面210的顶部和表面207的底部之间的间隙。As noted above, surfaces of the anesthesia system that move past each other from above or below, such as surfaces 210 and 207, have close tolerance or flexible seals at their interface 211 to avoid material on the surfaces becoming trapped in gaps or jammed. between surfaces. In one embodiment, the flexible seals used are "bulb seals", as known to those skilled in the art. After application, when surface 210 is retracted or folded into the system, the bead flexes to completely fill the gap between the top of surface 210 and the bottom of surface 207 .
图2B示出了应用至本发明的麻醉系统的球缘密封条225。如图2B中所示，至少一个球缘型密封条225和优选地多个球缘型密封条225被设置在表面207和210的接合面211处。在多个实施方式中，本领域已知的其它密封件，如刷型密封件(wiper type seal)或者挠性泡沫，可用于本发明的麻醉系统。Figure 2B shows a bulb seal 225 applied to the anesthesia system of the present invention. As shown in FIG. 2B , at least one bead 225 and preferably a plurality of bead 225 are disposed at the interface 211 of surfaces 207 and 210 . In various embodiments, other seals known in the art, such as wiper type seals or flexible foams, may be used in the anesthesia systems of the present invention.
在一个实施方式中，采用的密封件包括抗菌处理，以保证表面210在界面211处被挠性密封件滑过时不被微生物污染。该抗菌处理是本领域已知的。例如，本领域已知的抗菌银离子表面处理可应用于本发明。在另一个实施方式中，所应用的密封件可以是泡沫类型，其在应用之前被浸入抗菌溶液中。本领域已知的多种其它抗菌密封件可应用于该麻醉系统中。In one embodiment, the seal employed includes an antimicrobial treatment to ensure that surface 210 is not contaminated by microorganisms as the flexible seal slides across at interface 211 . Such antimicrobial treatments are known in the art. For example, antimicrobial silver ion surface treatments known in the art may be applied in the present invention. In another embodiment, the applied seal may be of the foam type which is dipped in an antimicrobial solution prior to application. Various other antimicrobial seals known in the art may be employed in the anesthesia system.
为了进一步减少交叉污染的机会，在一个实施方式中，工作表面210的顶表面和AO工作表面207的顶和底表面涂覆有抗菌处理，如银离子。在仍另一个实施方式中，抗菌处理为处理表面贴面(decal)的形式，其被施加在工作表面210的顶表面和AO工作表面207的顶和底表面上。贴面(或转印)是塑料、布、纸或陶瓷基底，其可通过接触，通常通过热或水的帮助，而被移动到另一个表面上。在一个实施方式中，在将贴面应用至麻醉系统的一个或多个表面上之前，表面贴面通过使用本领域已知的任何合适的表面涂覆方法而涂覆有抗菌处理。该抗菌处理涂覆表面贴面可由麻醉系统的用户定期更换。此外，对本领域普通技术人员很明显，多种其它商业可购得的抗菌处理和涂层可用于上述的目的。To further reduce the chance of cross-contamination, in one embodiment, the top surface of work surface 210 and the top and bottom surfaces of AO work surface 207 are coated with an antimicrobial treatment, such as silver ions. In yet another embodiment, the antimicrobial treatment is in the form of a treatment surface decal that is applied to the top surface of work surface 210 and the top and bottom surfaces of AO work surface 207 . A veneer (or transfer) is a plastic, cloth, paper or ceramic substrate that can be moved to another surface by contact, usually with the aid of heat or water. In one embodiment, the surface veneer is coated with an antimicrobial treatment using any suitable surface coating method known in the art prior to application of the veneer to one or more surfaces of the anesthesia system. The antimicrobial treatment coated surface veneer may be periodically replaced by the user of the anesthesia system. Additionally, it will be apparent to those of ordinary skill in the art that a variety of other commercially available antimicrobial treatments and coatings may be used for the purposes described above.
在可选的实施方式中，通过使用商业可获得的抗菌处理而使得工作表面210的顶表面和AO工作表面207的顶和底表面永久地消毒。例如，可应用膜基溶液(film-basedsolution)，其具有固有的微几何结构，在被应用至表面上时使得表面抵抗微生物生长。In an alternative embodiment, the top surface of work surface 210 and the top and bottom surfaces of AO work surface 207 are permanently disinfected through the use of commercially available antimicrobial treatments. For example, film-based solutions may be applied, which have an inherent microgeometry that, when applied to a surface, renders the surface resistant to microbial growth.
在可选的实施方式中，为了防止污染，麻醉系统还被配置有至少一个紫外线(UV)光源，其在本领域已知具有抗菌效果。例如，可使用被设计成消毒表面的UV光源，该表面包括医学工业中使用的表面。如对本领域人员或普通技术人员很明显，适用于所述应用的任何其它常规的UV光源可用于消毒该麻醉系统。在一个实施方式中，UV光源被设置在麻醉系统的内部的一个或多个位置处，且在麻醉系统的工作表面210伸展或收回时被启动。在另一个实施方式中，连续地或周期性地启动所使用的UV光源预定时间段。根据本发明的实施方式，图2C示出了用于麻醉系统的UV光源235。如图所示，UV光源235被设置在主AO工作表面207下方，用于当CC被伸展且工作表面210露出时对麻醉系统的内表面进行照明。当表面210延伸出时，该UV光源235照亮并消毒在工作表面207下方形成的间隙，以及其它部件。In an optional embodiment, to prevent contamination, the anesthesia system is also equipped with at least one ultraviolet (UV) light source, which is known in the art to have an antimicrobial effect. For example, UV light sources designed to disinfect surfaces, including those used in the medical industry, may be used. Any other conventional UV light source suitable for the application may be used to sterilize the anesthesia system, as will be apparent to one of ordinary skill in the art. In one embodiment, the UV light source is positioned at one or more locations inside the anesthesia system and is activated when the working surface 210 of the anesthesia system is extended or retracted. In another embodiment, the UV light source used is activated continuously or periodically for a predetermined period of time. Figure 2C illustrates a UV light source 235 for an anesthesia system, according to an embodiment of the invention. As shown, a UV light source 235 is positioned below the main AO work surface 207 for illuminating the interior surfaces of the anesthesia system when the CC is extended and the work surface 210 is exposed. When the surface 210 is extended, the UV light source 235 illuminates and sterilizes the gap formed under the work surface 207, among other components.
在另一个实施方式中，提供了用于消毒麻醉系统的低成本系统，其可用于医院环境的多个系统。替代内建于麻醉系统中的UV光源，该实施方式中设置了UV光“棒(wand)”，其被周期地引入麻醉(和其它)系统的内部用于将系统消毒。在一个实施方式中，该“棒”是细的、UV光源元件，其被设置成用于麻醉系统的专门服务工具。该棒可通过用户在例行基础上引入麻醉系统的内部，用于对系统的内部进行消毒的目的。在一个实施方式中，麻醉系统被设置有用于插入UV光棒的进入孔。在另一个实施方式中，可将麻醉系统的一个或多个预定盖移除，以将UV光棒引入系统内。In another embodiment, a low cost system for decontaminating anesthesia systems is provided that can be used with multiple systems in a hospital setting. Instead of a UV light source built into the anesthesia system, a "wand" of UV light is provided in this embodiment, which is periodically introduced into the interior of the anesthesia (and other) system for disinfection of the system. In one embodiment, the "stick" is a thin, UV light source element configured as a specialized service tool for the anesthesia system. The wand may be introduced by the user into the interior of the anesthesia system on a routine basis for the purpose of disinfecting the interior of the system. In one embodiment, the anesthesia system is provided with an access port for insertion of a UV light rod. In another embodiment, one or more predetermined covers of the anesthesia system may be removed to introduce a UV light stick into the system.
在另一个实施方式中，麻醉系统的内部通过抗菌垫，或者浸有抗菌清洁剂的通用垫而被周期地清洁，用于杀菌。在该实施方式中，抗菌垫被临时地连接至工作表面210，且随着系统缩回而在主AO工作表面207下方被引入麻醉系统内。该抗菌垫是挠性的，且随着工作表面210缩进而摩擦AO工作表面207的底表面。在一个实施方式中，该抗菌垫由挠性棉质材料制成，其在移动进入麻醉系统中时向下按压，且在其横向移动经过系统的内表面时提供“擦拭”动作。在一个实施方式中，该抗菌垫浸有异丙醇或者任何其它现有的消毒剂。该抗菌垫可通过麻醉系统的相继伸展和缩回而提供多个擦拭动作，以保证抗菌处理。In another embodiment, the interior of the anesthesia system is periodically cleaned with an antimicrobial pad, or a general purpose pad impregnated with an antimicrobial cleaner, for sterilization. In this embodiment, an antimicrobial pad is temporarily attached to the work surface 210 and introduced into the anesthesia system below the main AO work surface 207 as the system is retracted. The antimicrobial pad is flexible and rubs against the bottom surface of the AO work surface 207 as the work surface 210 retracts. In one embodiment, the antimicrobial pad is made of a flexible cotton material that presses down as it moves into the anesthesia system and provides a "wiping" action as it moves laterally across the interior surfaces of the system. In one embodiment, the antimicrobial pad is impregnated with isopropyl alcohol or any other existing disinfectant. The antimicrobial pad can provide multiple wiping motions through sequential extension and retraction of the anesthesia system to ensure antimicrobial treatment.
在可选实施方式中，该垫被永久地安装在工作表面210的边缘，且保持在AO工作表面207的下方，并且经由在接合面211处的毛细作用而周期地保持有商业可购买的抗菌溶液。图2D示出了根据本发明的实施方式的永久性地连接至麻醉系统的抗菌垫。如图所示，抗菌垫245连接至表面210，使得当CC伸展时垫245擦拭AO主表面207的内表面。在一个实施方式中，用户或者生物医学服务人员可周期性地将异丙醇或者任何其它合适的消毒溶液倒在垫245上，以将垫245再填充，并对麻醉系统的内表面消毒。In an alternative embodiment, the pad is permanently mounted on the edge of the work surface 210 and remains below the AO work surface 207 and is periodically maintained with commercially available antimicrobial solution. Figure 2D illustrates an antimicrobial pad permanently attached to an anesthesia system, in accordance with an embodiment of the present invention. As shown, antimicrobial pad 245 is attached to surface 210 such that pad 245 wipes the inner surface of AO major surface 207 when CC is stretched. In one embodiment, the user or biomedical service personnel may periodically pour isopropyl alcohol or any other suitable sanitizing solution over the pad 245 to refill the pad 245 and disinfect the interior surfaces of the anesthesia system.
此外，对本领域普通技术人员很明显，使用商业可购买的表面和材料处理的可选实施方式，作为限制麻醉系统的暴露和内表面上的微生物生长的方式，也在本发明的实质范围内。Furthermore, it will be apparent to those of ordinary skill in the art that alternatives to the use of commercially available surface and material treatments as a means of limiting exposure of the anesthesia system and microbial growth on interior surfaces are also within the spirit of the invention.
在另一个实施方式中，通过麻醉系统200的用户控制装置而电动驱动和电启动CC202相对于AO 204的移动。在一个实施方式中，单个用户启动导致CC 202相对于AO 204的预编程电动移动。在一个实施方式中，如果用户致动的CC 202电动移动遇到障碍，则CC 202的移动自动停止。在一个实施方式中，移动电机的电流的改变用于探测障碍。同时，在另外的或可选的实施方式中，声音报警和/或视觉报警的形式的障碍信号，例如闪灯，用于指示障碍且使CC 202的移动停止。在一个实施方式中，将现有的用于照明麻醉系统的多个构件的灯用作报警闪灯。在一个实施方式中，现有的灯包括在接近图1A中的点196的顶部区域中的用于聚焦在接近图1A的点197附近的汽化器和/或工作表面上的灯。In another embodiment, movement of the CC 202 relative to the AO 204 is electrically driven and electrically activated by user controls of the anesthesia system 200 . In one embodiment, a single user initiation results in a preprogrammed electrical movement of the CC 202 relative to the AO 204 . In one embodiment, if the user-actuated motorized movement of CC 202 encounters an obstacle, movement of CC 202 automatically stops. In one embodiment, changes in the current of the mobile motor are used to detect obstacles. Meanwhile, in an additional or alternative embodiment, an obstacle signal in the form of an audible alarm and/or a visual alarm, such as a flashing light, is used to indicate an obstacle and stop the movement of the CC 202 . In one embodiment, existing lamps for illuminating various components of the anesthesia system are used as warning flashers. In one embodiment, existing lights include lights in the top region near point 196 in FIG. 1A for focusing on the vaporizer and/or work surface near point 197 in FIG. 1A .
此外，图2A示出了在CC 202的底部的至少一个地板接触点225。随着CC 202从AO204和主四轮台车底座214移动离开相当大的距离，由于倾覆和强度考虑，将系统的CC 202部分从AO 204悬臂支撑是不实际的。因此，CC 202使用其本身的地面接触点225以允许负载支撑，被直接传递至地板而不是经由AO 204推车框架，负载支撑可包括一个或多个用户倚靠在该CC 202上。Additionally, FIG. 2A shows at least one floor contact point 225 at the bottom of CC 202 . With the CC 202 moving a substantial distance away from the AO 204 and main four-wheel dolly mount 214, it is not practical to cantilever the CC 202 portion of the system from the AO 204 due to overturning and strength considerations. Thus, the CC 202 uses its own ground contact points 225 to allow load support, which may include one or more users leaning on the CC 202 , to be transferred directly to the floor rather than via the AO 204 cart frame.
在一个实施方式中，该至少一个接触点225能够在完全360度方式提供同等的水平摩擦，且是但不限于可移动负载转移机构的旋转轨迹球类型或者脚轮类型(具有多个轮)，其允许直排移动以及侧向移动。使用可移动接触保证CC 202和麻醉系统200可被整体地和快速地移动或重定位，甚至在“打开”或完全伸展配置。在一个实施方式中，通过锁定AO 204下方的两个或四个轮的中间制动系统而锁定麻醉系统200。在一个实施方式中，该中间制动系统经由本领域技术人员已知的脚踏板215而控制，或者经由在麻醉系统的移动手柄上的一个或多个位置处的手杆而控制，将在下文中更详细地说明。该手杆提供了更加直接的锁定/解锁配置。In one embodiment, the at least one point of contact 225 is capable of providing equivalent horizontal friction in a full 360 degree manner and is, but not limited to, a rotating trackball type or caster type (with multiple wheels) of a movable load transfer mechanism, which Allows in-line movement as well as sideways movement. The use of movable contacts ensures that CC 202 and anesthesia system 200 can be moved or repositioned integrally and rapidly, even in an "open" or fully extended configuration. In one embodiment, the anesthesia system 200 is locked by locking the middle brake system of two or four wheels below the AO 204 . In one embodiment, the intermediate braking system is controlled via a foot pedal 215 known to those skilled in the art, or via a hand lever at one or more positions on the mobile handle of the anesthesia system, which will be described in more detail in the text. This lever provides a more straightforward lock/unlock configuration.
在一个实施方式中，当CC 202被移动进其底座、靠在AO 204上的锁定位置时，该至少一个接触点225从地板脱离，仅留下初始的标准四个脚轮与地板接触。可选地，即使在锁定位置，也可保持CC 202与地板之间的接触。在一个实施方式中，接触点225被配置有合适的几何结构，以在接触点225伸展时移动地板上的障碍物，其包括但不限于诸如盖或挠性弹簧等的元件，其与地板非常接近且从而在障碍物接近地板上的接触点225之前推动或升高障碍物。In one embodiment, when the CC 202 is moved into its base, locked position against the AO 204, the at least one point of contact 225 disengages from the floor, leaving only the initial standard four casters in contact with the floor. Optionally, contact between the CC 202 and the floor may be maintained even in the locked position. In one embodiment, the contact point 225 is configured with suitable geometry to move obstacles on the floor when the contact point 225 is extended, including but not limited to elements such as covers or flex springs that are in close contact with the floor. Approaching and thereby pushing or raising the obstacle before it approaches the contact point 225 on the floor.
因此，在多个实施方式中，CC的地板接触点和移动机构允许载荷承载至由其从AO移动离开形成的工作空间区域，而没有倾覆或损坏的风险。如下文中所说明，将CC从AO分离所暴露的另外的可使用空间可由临床医生用于其供应品和工具，解决了在较小机器上的“有限工作空间”的问题。另外，这还允许麻醉师在非常拥挤或有很多人和各种设备的环境中形成“其自己的空间”。该空间允许其将临床任务和工作流程与更加文件和办公相关的分离开。Thus, in various embodiments, the CC's floor contact points and movement mechanism allow load carrying to the workspace area formed by its movement away from the AO without risk of tipping or damage. As explained below, separating the CC from the AO exposes additional usable space that can be used by the clinician for their supplies and tools, solving the problem of "limited workspace" on smaller machines. Additionally, this allows the anesthesiologist to form "his own space" in very crowded or environments with many people and various equipment. This space allows it to separate clinical tasks and workflow from more documentation and office related ones.
图2A示出了远离AO 204的呼吸回路连接区域206的角度铰接。该呼吸回路连接区域206是可伸缩和向外旋转的，以及通过AO 204位于右手侧且CC 202移到左侧为临床医生产生“坐舱”区域。在该配置中，该AO 204可被有利地设置成远离患者且在临床区域之外，但CC 202和所有的临床工具可被设置成与患者密切接近。已观察到，呼吸回路区域206的额外的角旋转还为临床医生露出了额外的工作空间212。FIG. 2A shows the angular articulation of the breathing circuit connection region 206 away from the AO 204 . The breathing circuit connection area 206 is telescopic and outwardly rotated, and creates a "cockpit" area for the clinician with AO 204 on the right hand side and CC 202 moved to the left. In this configuration, the AO 204 can advantageously be positioned away from the patient and out of the clinical area, but the CC 202 and all clinical tools can be positioned in close proximity to the patient. It has been observed that the additional angular rotation of the breathing circuit region 206 also exposes additional working space 212 for the clinician.
在本发明的多个实施方式中，麻醉系统及其部件的伸缩运动和角旋转移动可展开为多种配置，从而让CC 202被设置在相对于AO 204的多个位置处。如上相对于图1A所示，三种类型的移动可用于在本发明的麻醉系统中相对于AO 204而设置CC 202。In various embodiments of the invention, the telescoping and angular rotational movement of the anesthesia system and its components can be deployed in various configurations, allowing the CC 202 to be positioned at various positions relative to the AO 204 . As shown above with respect to FIG. 1A, three types of movement may be used to position CC 202 relative to AO 204 in the anesthesia system of the present invention.
在一个实施方式中，旋转移动可用于将CC 202在接合处295以增量式(incremental)角度离开或朝向AO 204旋转。图2A和2E示出了本发明的麻醉系统的多种配置。图2A以本发明的麻醉系统200处于完全伸展和旋转打开位置开始，其中旋转角度275为45度的完全打开位置。角度275从最大的45度增量式地旋转至最小零度，直到麻醉系统200的CC部分202处于旋转闭合或折叠位置，且因此与系统旋转地齐平，其中角度275位于零度，如图2E中所示。在一个实施方式中，旋转增量为以预定角度步进的，例如每步5度，或者使用摩擦轴承连续地控制为任何选择的角度。在优选的实施方式中，在零度角度具有棘爪(即，系统200的闭合或折叠位置)，从而当系统200旋转完全闭合时，其以确定的方式“咔嗒”关闭。In one embodiment, rotational movement may be used to rotate CC 202 away from or toward AO 204 at junction 295 by incremental angles. Figures 2A and 2E illustrate various configurations of the anesthesia system of the present invention. FIG. 2A begins with the anesthesia system 200 of the present invention in a fully extended and rotated open position, where the angle of rotation 275 is 45 degrees. The angle 275 is incrementally rotated from a maximum of 45 degrees to a minimum of zero degrees until the CC portion 202 of the anesthesia system 200 is in a rotationally closed or folded position, and thus rotationally flush with the system, with the angle 275 at zero degrees, as in FIG. 2E shown. In one embodiment, the rotational increments are in predetermined angular steps, eg, 5 degree steps, or continuously controlled to any chosen angle using friction bearings. In a preferred embodiment, there is a detent at zero degrees (ie, the closed or folded position of the system 200) so that when the system 200 is rotated fully closed, it "clicks" closed in a deterministic manner.
在另一个实施方式中，在接合部296处的平移移动可以将CC 202伸缩地或线性地压缩和折叠回至AO 204或者将CC 202从AO 204伸展离开。图2F和2G示出了随着CC 202被压缩并折叠回至AO 204，在接合部296处将系统200平移移动的范围。在一个实施方式中，可用于将CC 202压缩和折叠回至AO 204的平移移动范围是14.5英寸。这里，应该注意到，在点296处的平移移动还导致在接合297处的平移移动298。In another embodiment, translational movement at junction 296 may telescopically or linearly compress and fold CC 202 back into AO 204 or extend CC 202 away from AO 204 . 2F and 2G illustrate the extent to which the system 200 is moved in translation at the junction 296 as the CC 202 is compressed and folded back into the AO 204 . In one embodiment, the range of translational movement available to compress and fold the CC 202 back into the AO 204 is 14.5 inches. Here, it should be noted that translational movement at point 296 also results in translational movement 298 at junction 297 .
本领域技术人员应理解，旋转和平移移动可组合以具有CC 202相对于AO 204的多个位置。因此，在一个实施方式中，可通过将CC 202在接合297处从AO 204旋转或平移离开而使用工作空间299，如图2H和2I所示。图2H示出了当CC 202以例如5度角度的至少一个增量移动从AO 204离开的角位移。图2I示出了根据一个实施方式，在CC 202以45度角度从AO204完全旋转离开时的角位移，但是麻醉系统200没有为额外的工作空间展开或伸缩。此外，CC可从AO伸出(平移移动)，形成或露出额外的工作空间，如上所述。Those skilled in the art will understand that rotational and translational movements may be combined to have multiple positions of CC 202 relative to AO 204 . Thus, in one embodiment, workspace 299 may be used by rotating or translating CC 202 away from AO 204 at joint 297, as shown in Figures 2H and 2I. FIG. 2H shows the angular displacement away from AO 204 when CC 202 moves in at least one increment of angle, eg, 5 degrees. FIG. 2I illustrates angular displacement when CC 202 is fully rotated away from AO 204 at a 45 degree angle, but anesthesia system 200 is not deployed or retracted for additional workspace, according to one embodiment. In addition, the CC can protrude (translationally move) from the AO, creating or exposing additional workspace, as described above.
因此，在多个实施方式中，本发明的麻醉系统的CC可单侧地移动朝向患者和从主台车设备离开，该主台车设备包括AO、气瓶和管道气体连接。由于CC载有用于临床医生对患者的直接处理所必需的所有的临床控制装置和视觉显示器，这些区域保持在临床医生处理患者时易于接触和看见处。该所得到的系统结构消除了对与CC的外部连接的需要，且仅要求提供“清洁的”气管道和电源。在一个实施方式中，CC本身可用作小的麻醉系统，使用较长的连接带连接至电和气源。Thus, in various embodiments, the CC of the anesthesia system of the present invention can be moved unilaterally toward the patient and away from the main cart equipment, which includes the AO, gas cylinders, and tubing gas connections. Since the CC carries all the clinical controls and visual displays necessary for the clinician's direct handling of the patient, these areas remain within easy reach and visibility of the clinician while handling the patient. The resulting system architecture eliminates the need for external connections to the CC and requires only "clean" gas lines and power to be provided. In one embodiment, the CC itself can be used as a small anesthesia system, connected to electrical and air sources using longer connecting straps.
在一个实施方式中，麻醉系统包括呼吸回路连接端口，其可旋转和水平地回转，以改进呼吸回路管的挠性，用于在杂乱和物理受限的医疗环境中布线。如上所述，在手术室(OR)中的物理受限是由于但不限于手术类型，OR布局，使用中的设备，室中需要的人员数量，人员位置，以及其它原因，这增加了对麻醉系统的设置和结构的需要，特别是涉及呼吸管口连接。呼吸管口连接通常限制系统的移动，且如果以错误的方向扭曲或扭转，则存在将呼吸管断开和扭结或扭曲的风险。In one embodiment, the anesthesia system includes a breathing circuit connection port that is rotatable and swivels horizontally to improve the flexibility of the breathing circuit tubing for routing in cluttered and physically constrained medical environments. As noted above, physical constraints in the operating room (OR) due to, but not limited to, type of surgery, OR layout, equipment in use, number of personnel required in the room, personnel location, and other reasons increase the risk of anesthesia. System set-up and construction needs, especially with respect to breathing tube connections. The snorkel connection typically limits movement of the system and if twisted or twisted in the wrong direction there is a risk of disconnecting the snorkel and kinking or twisting it.

图2K是图2J所示的本发明的旋转呼吸回路连接端口的放大正视图。Figure 2K is an enlarged front view of the rotating breathing circuit connection port of the present invention shown in Figure 2J.
图2L是图2J和2K所示的本发明的旋转呼吸回路连接端口的放大后视图。Figure 2L is an enlarged rear view of the rotating breathing circuit connection port of the present invention shown in Figures 2J and 2K.
同时参考图2J、2K和2L，呼吸回路连接端口232包括旋转本体，旋转本体具有旋转盖234和端口壳体236，该旋转盖234嵌入在临床中心(CC)202的底部部分202b上的平坦表面233中，且端口壳体236从旋转盖234向下延伸，其中在一个实施方式中，端口壳体为圆柱形状且限定用于接收气体的空间。该旋转本体被插入CC 102中，从而旋转盖234与顶平坦表面233平齐，且因此，在与CC 202的顶平坦表面233相同的平面中，同时旋转本体的剩余部分被设置在CC 202的顶平坦表面233下方。整个旋转本体呼吸回路连接端口232随着端口232的任何部分的移动而移动。Referring simultaneously to FIGS. 2J , 2K and 2L, the breathing circuit connection port 232 includes a swivel body with a swivel cap 234 that fits into a flat surface on the bottom portion 202b of the clinical center (CC) 202 and a port housing 236 233 , and a port housing 236 extends downwardly from the swivel cover 234 , wherein in one embodiment, the port housing is cylindrical in shape and defines a space for receiving gas. The swivel body is inserted into the CC 102 so that the swivel cover 234 is flush with the top flat surface 233 and thus in the same plane as the top flat surface 233 of the CC 202 while the rest of the swivel body is disposed on the top flat surface 233 of the CC 202. below the top planar surface 233 . The entire rotating body breathing circuit connection port 232 moves as any portion of the port 232 moves.
此外，呼吸回路连接端口232包括至少一个分支，其是吸入、呼出，或其结合。在一个实施方式中，在呼吸回路连接端口232上的至少一个分支是连接至麻醉气体供应管用于接收气体的入口，和用于连接呼吸管的近端的出口，其中呼吸管的远端连接至患者。在一个实施方式中，入口239(图2L中所示)和出口238(图2K中所示)被设置成与端口壳体236的外部分垂直，使得其彼此直接相反(彼此设置成180度)，且使得出口238被设置成与端口壳体236的外、竖直部分垂直，从而其从系统的前表面240伸出，同时入口239保持在系统的内部分中。Additionally, breathing circuit connection port 232 includes at least one branch, which is inhalation, exhalation, or a combination thereof. In one embodiment, at least one branch on the breathing circuit connection port 232 is an inlet connected to the anesthesia gas supply tube for receiving gas, and an outlet for connecting the proximal end of the breathing tube, wherein the distal end of the breathing tube is connected to patient. In one embodiment, inlet 239 (shown in FIG. 2L ) and outlet 238 (shown in FIG. 2K ) are positioned perpendicular to the outer portion of port housing 236 such that they are directly opposite each other (set 180 degrees from each other) , and such that the outlet 238 is positioned perpendicular to the outer, vertical portion of the port housing 236 so that it protrudes from the front face 240 of the system, while the inlet 239 remains in the inner portion of the system.
在另一个可选的实施方式中，入口和出口被设置在端口壳体236上，使得入口直接位于端口壳体236的外、底部分237的下方并连接至其上，且出口被设置成与端口壳体236的外、竖直部分垂直，使得其从系统的前表面240伸出。In another alternative embodiment, the inlet and outlet are arranged on the port housing 236 such that the inlet is located directly below and connects to the outer, bottom portion 237 of the port housing 236 and the outlet is arranged in conjunction with The outer, vertical portion of the port housing 236 is vertical such that it protrudes from the front surface 240 of the system.
这里应该注意，入口和出口可被设置在端口壳体236的任何位置上，使得其不干扰管连接或者呼吸回路连接端口232的旋转移动。It should be noted here that the inlet and outlet can be positioned anywhere on the port housing 236 such that they do not interfere with the tube connection or the rotational movement of the breathing circuit connection port 232 .
在一个实施方式中，使用旋转机构来旋转呼吸回路连接端口232。在一个实施方式中，端口手动地旋转且摩擦配合。在一个实施方式中，端口是弹簧控制的，且如果没有以角度增量旋转则弹回至默认位置。在一个实施方式中，圆柱端口壳体是径向密封的。在一个实施方式中，常规的O型环被用于径向密封圆柱形端口壳体。在一个实施方式中，径向密封使得呼吸回路连接端口与圆柱壳体共同旋转。In one embodiment, the breathing circuit connection port 232 is rotated using a rotation mechanism. In one embodiment, the port is manually rotated and friction fit. In one embodiment, the port is spring controlled and springs back to a default position if not rotated in angular increments. In one embodiment, the cylindrical port housing is radially sealed. In one embodiment, conventional O-rings are used to radially seal the cylindrical port housing. In one embodiment, the radial seal is such that the breathing circuit connection port co-rotates with the cylindrical housing.
在一个实施方式中，旋转呼吸回路连接端口232关于轴线243在-15度至+15度范围内旋转，该轴线243与底部部分202b的平坦表面233正交(或垂直)且延伸穿过端口232的中间点，允许为通常用于麻醉应用中的呼吸回路过滤器留出完全空间。在一个实施方式中，过滤器可选地用于吸入和呼出端口两者。在一些情况下，与实际端口尺寸相比，可用的过滤器可以是大的。端口在相反的两角度方向上移动，从而产生的双方向移动范围可允许使用大的过滤器。In one embodiment, the rotating breathing circuit connection port 232 rotates within a range of -15 degrees to +15 degrees about an axis 243 that is normal (or perpendicular) to the planar surface 233 of the bottom portion 202b and extends through the port 232 The mid-point allows full clearance for the breathing circuit filter typically used in anesthesia applications. In one embodiment, filters are optionally used for both the inhalation and exhalation ports. In some cases, available filters may be large compared to the actual port size. The ports move in two opposite angular directions, resulting in a bi-directional range of motion that allows the use of large filters.
这里应该注意，可预见任意角度范围可用于本发明的旋转呼吸回路端口。选择-15度至+15度的范围以让患者回路管道从呼吸回路排出，同时避免管道中断(trapment)或夹紧情况。在一些情况下，取决于过滤器尺寸，使用较大角度可随着端口的旋转而引起过滤器被挤靠在呼吸回路的正面。再参考图2G，在默认配置中，旋转呼吸回路连接端口232被设置成使得呼吸管道连接出口238与CC 202的正面204垂直。It should be noted here that any range of angles is envisioned for use with the rotating breathing circuit port of the present invention. A range of -15 degrees to +15 degrees is selected to allow the patient circuit tubing to drain from the breathing circuit while avoiding tubing trapments or pinch situations. In some cases, depending on the filter size, using a larger angle can cause the filter to be squeezed against the front of the breathing circuit as the port is rotated. Referring again to FIG. 2G , in a default configuration, the rotating breathing circuit connection port 232 is positioned such that the breathing tube connection outlet 238 is perpendicular to the front face 204 of the CC 202 .
图2M示出了旋转呼吸回路连接端口232处于第二配置的实施方式，其中呼吸管连接出口238朝向临床中心(CC)202的右侧旋转。因此，在一个实施方式中，呼吸回路连接端口关于穿过呼吸回路端口232的中心的竖直轴线朝向CC 202的右侧旋转15度。FIG. 2M shows an embodiment in which the rotating breathing circuit connection port 232 is in a second configuration in which the breathing tube connection outlet 238 is rotated toward the right side of the clinical center (CC) 202 . Thus, in one embodiment, the breathing circuit connection port is rotated 15 degrees toward the right of CC 202 about a vertical axis passing through the center of breathing circuit port 232 .
图2N是处于第三配置的旋转呼吸回路连接端口232的一个实施方式的示意图，其中将呼吸管连接出口238朝向临床中心(CC)202的左侧旋转。因此，在一个实施方式中，呼吸回路连接端口关于穿过呼吸回路端口232的竖直轴线朝向CC 202的左侧旋转15度。2N is a schematic illustration of one embodiment of a rotated breathing circuit connection port 232 in a third configuration with the breathing tube connection outlet 238 rotated toward the left side of the clinical center (CC) 202 . Thus, in one embodiment, the breathing circuit connection port is rotated 15 degrees toward the left of CC 202 about a vertical axis through breathing circuit port 232 .
在多种实施方式中，旋转呼吸回路连接端口232可在其移动范围内彼此独立地旋转。在一个实施方式中，旋转呼吸回路连接端口232被设置成彼此间隔最小距离以避免在旋转中干扰。在一个实施方式中，该最小距离是大约120mm。In various embodiments, the rotating breathing circuit connection ports 232 are rotatable independently of one another throughout their range of motion. In one embodiment, the rotating breathing circuit connection ports 232 are positioned at a minimum distance from each other to avoid interference during rotation. In one embodiment, the minimum distance is about 120mm.
在一个实施方式中，端口以角度增量旋转。在一个实施方式中，端口以1度增量旋转。在一个实施方式中，端口壳体36的外直径范围从17-27mm。在一个实施方式中，端口壳体具有22mm的外直径。在一个实施方式中，端口壳体236的内直径为10-20mm的范围。在一个实施方式中，端口壳体236具有15mm的内直径。In one embodiment, the port is rotated in angular increments. In one embodiment, the port is rotated in 1 degree increments. In one embodiment, the outer diameter of the port housing 36 ranges from 17-27 mm. In one embodiment, the port housing has an outer diameter of 22mm. In one embodiment, the inner diameter of the port housing 236 is in the range of 10-20 mm. In one embodiment, port housing 236 has an inner diameter of 15 mm.
在一个实施方式中，可将呼吸回路连接端口232移除以进行清洁。在一个实施方式中，各呼吸回路连接端口的顶表面或旋转盖234是半透明的。在一个实施方式中，呼吸回路连接端口包括呼吸回路止回阀，其可通过呼吸回路连接端口的半透明壳体观察。在另一个实施方式中，呼吸回路连接端口的顶表面或旋转盖234是半透明的且还包括信息投影灯以在流体通过端口的时候进行指示，从而用户可观察呼吸回路止回阀的动作，如下文将详细地说明。In one embodiment, breathing circuit connection port 232 is removable for cleaning. In one embodiment, the top surface or swivel cover 234 of each breathing circuit connection port is translucent. In one embodiment, the breathing circuit connection port includes a breathing circuit check valve that is viewable through the translucent housing of the breathing circuit connection port. In another embodiment, the top surface of the breathing circuit connection port or swivel cover 234 is translucent and also includes information projection lights to indicate when fluid is passing through the port so that the user can observe the breathing circuit check valve action, As will be described in detail below.

如图9A中所示，在一个实施方式中，AO 904包括系统状态计算机(SSC)905，其用于将信息传送至用户，该信息关于麻醉系统的气、电、软件(SW)和通信功能的状态。该SSC 905将与麻醉系统的技术状态相关的所有信息收集至一个小的显示器单元中。As shown in Figure 9A, in one embodiment, the AO 904 includes a System Status Computer (SSC) 905 for communicating information to the user about the anesthesia system's pneumatic, electrical, software (SW) and communication functions status. The SSC 905 collects all information related to the technical status of the anesthesia system into a small display unit.
这为用户提供麻醉系统的操作和功能信息从系统所提供的治疗相关的临床信息的直观分离(intuitive separation)。该SSC 905从主临床显示器单元(未示出)分离功能，且提供技术测量从临床护理所直接使用的直观分离。This provides the user with an intuitive separation of operational and functional information of the anesthesia system from therapy-related clinical information provided by the system. The SSC 905 separates functions from the main clinical display unit (not shown) and provides an intuitive separation of technical measurements from direct use in clinical care.
在多种实施方式中，SSC 905提供的信息例如：管道气压，气瓶气压，AC电源状态，DC电源状态，备用电源(例如，电池)状态，软件版本，内部CPU序列号和修改版本，系统时间和日期，计时器和报警状态，单元操作时间，最后校验和状态等等。该信息可转换为数字形式或经由填充条(fill bar)或者压力计的仿真而图形示出。In various embodiments, the SSC 905 provides information such as: pipeline air pressure, cylinder air pressure, AC power status, DC power status, backup power (e.g., battery) status, software version, internal CPU serial number and revision, system Time and date, timer and alarm status, unit operating time, last checksum status and more. This information can be converted into numerical form or shown graphically via a fill bar or simulation of a manometer.
在一个实施方式中，即使在麻醉系统断电或从电源断开时，SSC 905也保持通电，以显示其信息。这样，SSC 905保持向用户持续准备提供所有数据，但特别是气瓶压力和管道压力而不需要启动麻醉系统的主要部分。当麻醉系统的电源被断开以节省电能时，SSC905可以睡眠/休眠模式运行，且其显示器由单个用户触摸而开启。SSC 905能够以电池电源操作，允许观察系统状态，即使系统没有连接至AC主电源。现有技术系统使用混合的机械测量仪器和临床显示器单元上显示的测量，以将系统状态信息传递至用户。在一个实施方式中，通过使用平坦的液晶显示器(LCD)技术，SSC 905可被设置在AO的透明表面下方，例如平坦工作表面下方。收集电子形式的所有相关系统信息排除了对机械测量仪器的需要，机械测量仪器占用麻醉系统的可用表面的较大空间。在该AO中，通常用于常规系统中的机械测量仪器的空间被释放，且更好地用于存储或其它办公室类型功能。图9B提供了SSC905的示意图。In one embodiment, the SSC 905 remains powered to display its information even when the anesthesia system is powered off or disconnected from the power source. In this way, the SSC 905 maintains a constant readiness to the user providing all data, but especially cylinder pressure and line pressure without the need to activate the main part of the anesthesia system. When the anesthesia system is powered off to conserve power, the SSC905 can run in sleep/hibernation mode with its display turned on by a single user touch. The SSC 905 is capable of operating on battery power, allowing observation of system status even when the system is not connected to AC mains power. Prior art systems use a mix of mechanical gauges and measurements displayed on a clinical display unit to convey system status information to the user. In one embodiment, by using flat liquid crystal display (LCD) technology, the SSC 905 may be disposed beneath a transparent surface of the AO, such as a flat work surface. Collecting all relevant system information in electronic form obviates the need for mechanical gauges, which take up a large amount of available surface area of the anesthesia system. In this AO, the space normally used for mechanical gauges in conventional systems is freed and better used for storage or other office type functions. Figure 9B provides a schematic diagram of SSC905.
信息投影灯Information Projector Lamp
在本发明的一个实施方式中，提供与报警相关的系统区域直接光照，例如，麻醉系统的任何区域被怀疑正经历技术问题，从而明白地和直观地将用户的注意力引导至报警所反映的问题的可能源。因此，本发明的信息投影灯通过照亮麻醉系统的引起或将要引起反常/报警情况的部分而指示不正常的操作情况。In one embodiment of the invention, direct lighting is provided for areas of the system that are relevant to the alarm, for example, any area of the anesthesia system that is suspected to be experiencing a technical problem, thereby clearly and intuitively directing the user's attention to the area reflected in the alarm. possible source of the problem. Accordingly, the information projection light of the present invention indicates abnormal operating conditions by illuminating the portion of the anesthesia system that causes or is about to cause an abnormal/alarm condition.
例如，在麻醉系统中，由于“卡住(sticking)”止逆阀(止回阀)的情况，可出现不能为患者换气。尽管报警信息指示可产生低的换气情况，本发明的直接灯照特征可引起红色闪烁光从止回阀区域发射出来，从而将用户的注意力引导至潜在的问题源。在一个实施方式中，该光照可能实质上非常分散，使得整个止回阀圆顶照亮为红色或其它颜色。在多个实施方式中，如果系统的多于一个功能引起报警，则多个区域将闪烁光或者用户将被引导以顺序地对其进行逐步调试，如从最可能的至最不可能的。For example, in anesthesia systems, the inability to ventilate a patient may occur due to a "sticking" check valve (check valve) condition. The direct lighting feature of the present invention may cause a red flashing light to be emitted from the check valve area despite the warning message indicating that a low air change condition may be produced, thereby directing the user's attention to the potential source of the problem. In one embodiment, the lighting may be very diffuse in nature such that the entire check valve dome is illuminated red or another color. In various embodiments, if more than one function of the system causes an alarm, multiple areas will flash or the user will be directed to step through them sequentially, eg, from most likely to least likely.
在一个实施方式中，使用信息投影灯来识别合适的连接和工作区域。例如，很多已知的麻醉系统使用“共同气体出口”(CGO)用于吸入目的。这要求用户使用麻醉系统的控制装置来选择CGO作为共同气体的源。为了消除将患者连接至CGO而没有将其选择作为共同气体的源的错误，信息投影灯用于照亮涉及的端口和所连接的透明管。在一个实施方式中，如图9B中所示，如果没有选择CGO，则端口910被照亮为第一种颜色，例如琥珀色；如果通过旋转端口本体至水平位置而选择CGO，则端口被照亮为第二种颜色，例如绿色，而回路系统915的端口被同时地照亮为第三种颜色，例如红色，表示其没有被使用。In one embodiment, information projection lights are used to identify suitable connections and work areas. For example, many known anesthesia systems use a "common gas outlet" (CGO) for inhalation purposes. This requires the user to use the controls of the anesthesia system to select CGO as the source of the common gas. In order to eliminate the mistake of connecting the patient to the CGO without selecting it as the source of the common gas, an information projection lamp was used to illuminate the ports involved and the connected transparent tubing. In one embodiment, as shown in FIG. 9B, if CGO is not selected, port 910 is illuminated to a first color, such as amber; if CGO is selected by rotating the port body to a horizontal position, port 910 is illuminated. is illuminated in a second color, such as green, while the port of loop system 915 is simultaneously illuminated in a third color, such as red, to indicate that it is not in use.
现参考图10A和10B，提供开关1002作为在端口向上旋转至水平位置时启动的可移动CGO的两位置手杆。如图10A中所示，在第一位置，开关1002位于水平位置且致动CGO端口。第一位置优选地与系统的工作表面1004平行。如图10B中所示，在第二位置，开关1002优选地处于竖直位置，且与系统的工作表面1004正交，并将可移动CGO停用。图10A和10B还示出了呼吸回路连接端口1008，如上文中参考图2G、2H、2I、2J和2K所说明的。Referring now to Figures 10A and 10B, a switch 1002 is provided as a two-position hand lever for a moveable CGO that is activated when the port is rotated up to the horizontal position. As shown in Figure 10A, in a first position, the switch 1002 is in the horizontal position and actuates the CGO port. The first position is preferably parallel to the working surface 1004 of the system. As shown in Figure 10B, in the second position, the switch 1002 is preferably in a vertical position, normal to the system's work surface 1004, and deactivates the movable CGO. Figures 10A and 10B also show a breathing circuit connection port 1008, as described above with reference to Figures 2G, 2H, 2I, 2J, and 2K.
在袋至换气孔区域(bag to vent area)相似地使用信息投影灯。在一个实施方式中，当选择“换气孔”操作时，风箱本身可点亮为任何颜色，例如绿色。图10A和10B示出了当启动换气时风箱1006点亮。类似地，APL阀和回路压力计以不同的灯光颜色照亮，例如当麻醉系统的呼吸机处于停止的关闭状态时为琥珀色。Information projection lights are similarly used in the bag to vent area. In one embodiment, the bellows themselves may light up in any color, such as green, when the "vent" operation is selected. Figures 10A and 10B show that the bellows 1006 are illuminated when ventilation is activated. Similarly, the APL valve and circuit pressure gauge are illuminated with different light colors, such as amber when the anesthesia system's ventilator is in a stopped, off state.
在一个实施方式中，使用信息投影灯以通过直接照明所控制的功能而指示多个控制的状态(例如，开/关或接合/脱离或启动/停用)。例如，参考图1A，照亮袋153的臂以指示呼吸机停用/启动或者关/开状态；如果滤罐(canister)155从呼吸回路脱离和/或如果因呼吸气体中的高CO2而报警，则照亮CO2吸收滤罐155；如果因呼吸气监测器(容纳在图1C的生理监测器132中)的障碍而报警，则照亮侧流呼吸气监测器脱水器。在多种实施方式中，信息投影灯可用于根据呼吸机启动/停用状态、吸入开/关、辅助氧气开/关、二氧化碳旁路开/关等而指示蒸发器开/关、回路系统端口启用/停用。In one embodiment, information projecting lights are used to indicate the status of multiple controls (eg, on/off or engaged/disengaged or activated/deactivated) by directly illuminating the controlled function. For example, referring to FIG. 1A , the arm of bag 153 is illuminated to indicate ventilator deactivation/activation or off/on status; if canister 155 is disengaged from the breathing circuit and/or if due to highCO Alarm,CO2 absorbing canister 155 is illuminated; if alarm is due to obstruction of respiratory gas monitor (housed in physiological monitor 132 of FIG. 1C ), sidestream respiratory gas monitor dehydrator is illuminated. In various embodiments, information projection lights can be used to indicate vaporizer on/off, circuit system ports based on ventilator on/off status, inhalation on/off, supplemental oxygen on/off, carbon dioxide bypass on/off, etc. Enable/disable.
本领域普通技术人员应理解本发明的信息投影灯可根据用户需要/偏好而调节颜色，强度和/或闪光率。Those of ordinary skill in the art should understand that the information projection lamp of the present invention can be adjusted in color, intensity and/or flash rate according to user needs/preferences.
因此，本发明提供了经由使用与报警相关的怀疑的问题区域的精细光照以明确的和直观的方式而确定麻醉系统中的问题区域的系统和方法。通过本发明，用户被直接引导至需要检查或修正的系统区域，且不会从患者的护理发生不必要的分心和转移关注。此外，受影响的系统区域的可视照亮将允许OR中的其他人员帮助诊断或识别问题。通过信息投射可视照明，可清楚地确认系统的可操作元件中哪些的功能被接合或断开，减少了潜在的临床错误。Accordingly, the present invention provides a system and method for determining problem areas in an anesthesia system in an unambiguous and intuitive manner through the use of subtle illumination of suspected problem areas associated with alarms. With the present invention, the user is directed directly to areas of the system that require inspection or correction without unnecessary distraction and diversion from patient care. Additionally, visual illumination of affected system areas will allow other personnel in the OR to help diagnose or identify problems. Visible illumination through informational projections clearly confirms which of the system's operable elements are engaged or disengaged, reducing potential clinical errors.

在一个实施方式中，本发明涉及提供用户界面报警灯特征的麻醉输送系统。该特征在麻醉系统的图形用户界面(GUI)上提供光带，以使用户能不仅快速地确定报警是否被启动，还快速地确定启动报警的优先等级。在一个实施方式中，还在GUI的顶部角落处向用户显示照亮的彩色光带，以将用户的注意引至报警情况。此外，在一个实施方式中，照亮光带的颜色与报警情况的优先等级相关。例如，可显示黄色照亮带以指示中间优先级报警，而红色照亮带可与高优先报警相关。因此，用户界面报警灯特征让用户可快速确定报警情况，且当诸如麻醉师等的用户距麻醉系统太远而不能读取报警信息时是特别有利的。In one embodiment, the present invention is directed to an anesthesia delivery system that provides a user interface warning light feature. This feature provides a light bar on the anesthesia system's Graphical User Interface (GUI) to enable the user to quickly determine not only whether an alarm is activated, but also the priority level for activating the alarm. In one embodiment, an illuminated colored light strip is also displayed to the user at the top corner of the GUI to draw the user's attention to the alarm condition. Additionally, in one embodiment, the color of the illuminated light strip correlates to the priority level of the alarm condition. For example, a yellow illuminated band may be displayed to indicate a medium priority alarm, while a red illuminated band may be associated with a high priority alarm. Accordingly, the user interface alarm light feature allows a user to quickly determine an alarm condition, and is particularly advantageous when a user, such as an anesthesiologist, is too far away from the anesthesia system to read the alarm message.
图11A示出了根据本发明的实施方式的麻醉系统的示例性GUI屏幕。在一个实施方式中，GUI屏幕1100包括在左上角落的报警块区域1110。在其它实施方式中，报警块区域1110被设置在GUI 1100的任何方便的位置处。如图11A中所示，报警块区域1110没有着色(看起来是黑色)，表示没有报警情况，且因此没有显示报警信息。FIG. 11A shows exemplary GUI screens of an anesthesia system according to an embodiment of the present invention. In one embodiment, GUI screen 1100 includes an alarm tile area 1110 in the upper left corner. In other embodiments, the alert tile area 1110 is provided at any convenient location on the GUI 1100 . As shown in FIG. 11A, the alarm block area 1110 is not colored (looks black), indicating that there is no alarm condition, and therefore no alarm information is displayed.
图11B示出了根据本发明的一个实施方式的麻醉系统的另一个示例性GUI屏幕。如图11B中所示，GUI屏幕1114的报警块区域1112显示彩色(黄色)报警线，且报警信息显示“检查采样管线”。在一个实施方式中，所显示的黄色报警线表示中间等级报警。此外，在一个实施方式中，在预定的时间间隔之后显示的报警线变淡，而在另一实施方式中，该报警线以预定的时间间隔而间歇地显示。在另一个实施方式中，报警线显示为实线，直到相应的报警情况过去或者用户采取了预定的动作。还在图11B中示出，横过屏幕1114的顶中间部分的是彩色报警条1115。在一个实施方式中，报警条1115与报警块区域1112中的报警线的颜色(即，黄色)匹配。该报警条1115占据屏幕1114的较大区域，且比报警块1112的报警线更加突出地显示，从而有助于让看护者看见。FIG. 11B shows another exemplary GUI screen of the anesthesia system according to one embodiment of the present invention. As shown in FIG. 11B , the alarm block area 1112 of the GUI screen 1114 displays a colored (yellow) alarm line and the alarm message reads "Check Sampling Line". In one embodiment, a yellow alarm line displayed indicates an intermediate level alarm. Furthermore, in one embodiment, the displayed warning line fades after a predetermined time interval, while in another embodiment, the warning line is intermittently displayed at predetermined time intervals. In another embodiment, the warning line is displayed as a solid line until the corresponding warning condition passes or the user takes a predetermined action. Also shown in FIG. 11B , across the top middle portion of the screen 1114 is a colored alert bar 1115 . In one embodiment, the alarm bar 1115 matches the color of the alarm lines in the alarm tile area 1112 (ie, yellow). This alarm bar 1115 takes up a larger area of the screen 1114 and is displayed more prominently than the alarm line of the alarm block 1112 to facilitate visibility by the caregiver.
图11C示出了根据本发明的实施方式的麻醉系统的另一个示例性的GUI系统。如图11C中所示，在GUI屏幕1118的第一报警块区域1116(部分地显示)显示第一彩色(红色)报警线。在一个实施方式中，该显示的红色报警线与高优先级的报警情况相关。图11C还示出了在第二报警块区域1120中显示的第二彩色(黄色)报警。在一个实施方式中，报警条1125的颜色与当前发生的最高优先级报警相关。根据该实施方式，在图11C中，由于高和中间优先级报警都启动，所以报警线是红色且与高优先级报警相关。在多个实施方式中，可在麻醉系统的GUI屏幕上同时地显示表示相同或不同报警优先级的多条报警线。Fig. 11C shows another exemplary GUI system of an anesthesia system according to an embodiment of the present invention. As shown in FIG. 11C , a first colored (red) alarm line is displayed in the first alarm block area 1116 (partially shown) of the GUI screen 1118 . In one embodiment, the displayed red alarm line is associated with a high priority alarm condition. FIG. 11C also shows a second colored (yellow) alert displayed in the second alert block area 1120 . In one embodiment, the color of the alarm bar 1125 correlates to the highest priority alarm currently occurring. According to this embodiment, in FIG. 11C the alarm line is red and is associated with the high priority alarm since both the high and medium priority alarms are activated. In various embodiments, multiple alarm lines representing the same or different alarm priorities can be displayed simultaneously on the GUI screen of the anesthesia system.
从自动报警限度恢复Recovery from automatic alarm limits
如本领域通常已知的，当使用采用报警的麻醉输送系统时，期望具有“自动限度”功能，其根据预定的算法自动地调节关于当前监测值的系统的报警限度。该功能通过将所有的报警迅速设置为合适的水平而消除对外科医生分别且冗余地将各报警参数的值调高和调低的需要。因此，还期望具有“取消”或者“恢复”功能，从而将报警设置回至自动限度启动之前的状态，以用于在例如报警自动限度值被意外启动，临床医生不想保持该自动生成的限度，和/或临床医生期望手动地设置报警限度的情况。As is generally known in the art, when using anesthesia delivery systems that employ alarms, it is desirable to have an "auto-limit" function that automatically adjusts the system's alarm limits with respect to currently monitored values according to a predetermined algorithm. This function eliminates the need for the surgeon to individually and redundantly adjust the value of each alarm parameter up and down by quickly setting all alarms to the appropriate level. Therefore, it is also desirable to have a "Cancel" or "Reset" function to set the alarm back to the state before the automatic limit was activated, for example, if the alarm automatic limit value is accidentally activated, the clinician does not want to maintain the automatically generated limit, and/or where the clinician desires to manually set the alarm limits.
本发明提供了结合至麻醉系统的“从自动限度恢复”的功能，其可以直觉和可预测的方式使用，从而与现有技术的麻醉系统相比增加了使用“自动限度”和“从自动限度恢复”的易用性。图12A示出了根据本发明的实施方式显示用于设置报警的多个图标的显示器屏幕1200。如图所示，显示器屏幕1200显示用于独立地设置报警限度的图标，该报警限度与多个医疗功能相关，包括但不限于‘压力(plimit)’1202，‘呼吸末CO2(EtCO2)’1204，和‘呼吸暂停’1206。该显示器屏幕1200还显示图标‘自动设置限度’1208，用于自动地设置报警限度。通过点击图标1202、1204或1206，用户可设置各个参数的报警限度，以及通过点击‘自动设置限度’图标1208，用户可使得多个预定参数自动调节。The present invention provides a "return from auto limits" functionality incorporated into the anesthesia system that can be used in an intuitive and predictable manner, thereby increasing the use of "auto limits" and "from auto limits" compared to prior art anesthesia systems. Recovery" ease of use. FIG. 12A illustrates a display screen 1200 displaying a plurality of icons for setting an alarm in accordance with an embodiment of the present invention. As shown, the display screen 1200 displays icons for independently setting alarm limits associated with a number of medical functions, including but not limited to 'pressure (plimit)' 1202, 'end tidal CO2 (EtCO2)' 1204 , and 'Apnea' 1206. The display screen 1200 also displays an icon 'Auto Set Limits' 1208 for automatically setting alarm limits. By clicking on icons 1202, 1204 or 1206, the user can set alarm limits for various parameters, and by clicking on the 'auto set limits' icon 1208, the user can cause a number of predetermined parameters to be automatically adjusted.
图12B示出了根据本发明的实施方式的显示多个用于设置报警的图标的另一种显示器屏幕。一旦点击该‘自动设置限度’图标1208，则自动地调节多个预定报警参数。在一个实施方式中，点击‘自动设置限度’图标1208引起EtCO2 1204参数的改变，其在图12A中示出为具有限度80至在图12B中示出为具有限度110。一旦点击‘自动设置限度’图标1208，则显示取消图标1210。用户可点击取消图标1210，以恢复至在点击“自动设置限度”图标1208之前存在的多个报警参数的值。在该功能以不期望的方式引起一个或多个报警参数改变的情况下，可由用户点击该取消图标1210以取消‘自动设置限度’功能的效果。由于不要求用户将一个或多个报警参数分别地调节至其初始值，所以该取消功能增加了‘自动设置限度’功能的易用性。用户可点击‘自动设置限度’图标1208，以观察该调节的报警参数值，且在该值是不合需要的情况下可点击取消图标1210以容易地恢复至初始值。如果没有点击取消图标1210，则调节的报警参数值继续用作现有的报警限度。一旦报警菜单退出，则取消图标1210被移除，且将来返回至报警菜单会显示与图12A相似的屏幕，而没有取消图标但将EtCO2设置至110mmHg的值。FIG. 12B illustrates another display screen displaying a plurality of icons for setting an alarm, according to an embodiment of the present invention. Once the 'Auto Set Limits' icon 1208 is clicked, a number of predetermined alarm parameters are automatically adjusted. In one embodiment, clicking on the 'Auto Set Limits' icon 1208 causes a change in the EtCO2 1204 parameter, which is shown with a limit of 80 in Figure 12A to with a limit of 110 in Figure 12B. Once the 'Auto Set Limits' icon 1208 is clicked, a cancel icon 1210 is displayed. The user may click on the cancel icon 1210 to revert to the values of various alarm parameters that existed prior to clicking on the "Auto Set Limits" icon 1208 . In the event that this function causes one or more alarm parameters to change in an undesired manner, the cancel icon 1210 may be clicked by the user to cancel the effect of the 'auto-set limits' function. This cancel function adds to the ease of use of the 'auto-set limits' function as it does not require the user to individually adjust one or more alarm parameters to their initial values. The user can click on the 'Auto Set Limits' icon 1208 to observe the adjusted alarm parameter value, and can click on the cancel icon 1210 to easily revert to the original value if the value is undesirable. If the cancel icon 1210 is not clicked, the adjusted alarm parameter value continues to be used as the existing alarm limit. Once the alarm menu is exited, the cancel icon 1210 is removed, and returning to the alarm menu in the future will display a screen similar to Figure 12A without the cancel icon but with EtCO2 set to a value of 110mmHg.
图12C示出了根据本发明的实施方式的显示用于设置报警的多个图标的另一种显示器屏幕。如图12C中所示，一旦点击取消图标1210，则通过点击‘自动设置限度’图标1208调节的报警参数值恢复至其初始状态。在一个实施方式中，点击取消图标1210使得EtCO21204参数(如图12B中所示为110)恢复至其初始值80，如图12C中所示。FIG. 12C illustrates another display screen displaying a plurality of icons for setting an alarm, according to an embodiment of the present invention. As shown in Figure 12C, once the Cancel icon 1210 is clicked, the alarm parameter value adjusted by clicking the 'Auto Set Limits' icon 1208 returns to its original state. In one embodiment, clicking on the cancel icon 1210 causes the EtCO21204 parameter (shown as 110 in Figure 12B) to revert to its initial value of 80, as shown in Figure 12C.
增强的流管可视化Enhanced flow tube visualization
在常规的麻醉输送和换气系统中，流管通常用作简单的、清楚的和可靠的机械方法来保证装置的适当操作-通常在电子失效的情况下或者作为电子流动读取的交叉校验。如图9B中所示，本发明可选地包括用作电子新鲜气流测量的备用的流管916的改进的可视化方法。在申请日为2010年5月7日，受让于本发明的申请人，发明名称为“Light EnhancedFlow Tube”，申请号为12/775,719的美国专利申请中说明了示例性的流管，在此通过引用结合其全部内容。In conventional anesthesia delivery and ventilation systems, flow tubes are often used as a simple, clear and reliable mechanical means of ensuring proper operation of the device - often in the event of electronic failure or as a cross-check for electronic flow readings . As shown in FIG. 9B, the present invention optionally includes improved visualization of flow tube 916 used as a backup for electronic fresh gas flow measurement. Exemplary flow tubes are described in U.S. Patent Application No. 12/775,719, assigned to the present invention, filed May 7, 2010, entitled "Light Enhanced Flow Tube," and is hereby Its entire contents are incorporated by reference.
无线近程传感器(wireless proximal sensor(s))Wireless Proximity Sensor(wireless proximal sensor(s))
在一个实施方式中，本发明提供了用于近程设置的单个的小的传感器方案，而没有返回至麻醉系统的管或连接口。使用直接设置在气道的小传感器提供了最佳的流动和压力测量信号。用于无线传感器的该集成对接装置不仅提供充电和信号连接，且还提供用于传感器在各病例之间或没有使用时的物理存储位置。在一个实施方式中，本发明的麻醉系统提供了具有无线芯片组的能经受住压热器作用的流动传感器，包括CPU电源以执行无线功能、传感器采样和处理。In one embodiment, the present invention provides a single small sensor solution for proximal placement without tubing or connections back to the anesthesia system. The use of small sensors placed directly in the airway provides the best flow and pressure measurement signals. This integrated docking device for wireless sensors not only provides charging and signal connections, but also provides a physical storage location for the sensors between cases or when not in use. In one embodiment, the anesthesia system of the present invention provides an autoclavable flow sensor with a wireless chipset, including CPU power to perform wireless functions, sensor sampling and processing.
在一个实施方式中，无线近程传感器提供在手术室环境中最远30英尺的可靠的通信。在多种实施方式中，可使用无线技术，例如802.15.4(Zigbee的低水平IEEE标准)，SynkroRF(由Freescale开发)，RF4CE(Industry Consortium)，ANT和/或ANT+，蓝牙，低功率蓝牙等等。在多种实施方式中，无线近程传感器配合在基于电池的功率分配中，且其设计是忍受高湿度环境。In one embodiment, the wireless proximity sensor provides reliable communication up to 30 feet away in an operating room environment. In various embodiments, wireless technologies such as 802.15.4 (a low-level IEEE standard for Zigbee), SynkroRF (developed by Freescale), RF4CE (Industry Consortium), ANT and/or ANT+, Bluetooth, Bluetooth Low Energy, etc. may be used Wait. In various embodiments, wireless proximity sensors are incorporated into battery-based power distribution and are designed to tolerate high humidity environments.
在一个实施方式中，使用具有以下特征的气道压力传感器：In one embodiment, an airway pressure sensor with the following characteristics is used:
○动态范围：-20至120cmH2O○Dynamic range: -20 to120cmH2O
○分辨率：0.01cmH2O(计算为约14-位分辨率)○ Resolution: 0.01cmH2 O (calculated as about 14-bit resolution)
○带宽：60Hz(用于板载模拟和数字过滤)○ Bandwidth: 60Hz (for onboard analog and digital filtering)
○输出(十取一(decimated))采样率：250Hz(4msec周期)○ Output (decimated) sampling rate: 250Hz (4msec period)
在一个实施方式中，使用具有以下特征的不同的压力传感器：In one embodiment, a different pressure sensor is used having the following characteristics:
○动态范围：±2.5cmH2O○Dynamic range: ±2.5cmH2 O
○分辨率：0.0004cmH2O(计算为约14-位分辨率)○ Resolution: 0.0004 cmH2 O (calculated as about 14-bit resolution)
○带宽：60Hz(用于板载模拟和数字过滤)○ Bandwidth: 60Hz (for onboard analog and digital filtering)
○输出(十取一)采样率：250Hz(4msec周期)○Output (one out of ten) sampling rate: 250Hz (4msec period)
使用无线传感器要求检测合适信号的损耗，例如多于12至50msec的数据漏失，从而使得使用系统的内部传感器。此外，无线电池监测预测信号损耗，并无缝地使用备用传感器系统。本发明的麻醉系统通过新鲜气流传感器和驱动气流传感器设置有该备用装置。这些传感器形成流动信息的冗余网络，用于对近程传感器进行误差检验和在无线近程传感器失效时继续换气输出。The use of wireless sensors requires detection of a loss of suitable signal, eg loss of data of more than 12 to 50 msec, thereby making use of the system's internal sensors. Additionally, wireless battery monitoring predicts signal loss and seamlessly uses backup sensor systems. The anesthesia system of the present invention is provided with this backup by means of a fresh air flow sensor and a drive air flow sensor. These sensors form a redundant network of streaming information for error checking of the proximity sensors and for continued ventilation output in the event of wireless proximity sensor failure.
在一个实施方式中，如图9C中所示，用于无线近程传感器921的内部“对接”站920被设置在麻醉系统中，提供了编码的数据通信通道以及用于为无线传感器电池再充电的电源。该无线近程传感器仅在物理地位于对接装置中时形成至麻醉系统的通信连接。要求用户将传感器从对接装置920移除并将其设置在接近的气道中。在一个实施方式中，使用如上所述的信息投影灯提供了传感器通道启动的信息。In one embodiment, as shown in Figure 9C, an internal "docking" station 920 for a wireless proximity sensor 921 is provided in the anesthesia system, providing an encoded data communication channel and for recharging the wireless sensor battery power supply. The wireless proximity sensor forms a communication link to the anesthesia system only when physically located in the docking device. The user is required to remove the sensor from the docking device 920 and place it in the approached airway. In one embodiment, sensor channel activation information is provided using an information projection lamp as described above.
在一个实施方式中，无线传感器被分为两部分，无线通信舱(pod)和连接至该无线通信舱的传感器舱。仅向麻醉系统提供通信的该无线通信舱被设置在对接装置中。例如，在一个实施方式中，无线通信“舱”被连接至“空速管”类型的流动传感器。In one embodiment, the wireless sensor is divided into two parts, a wireless communication pod and a sensor pod connected to the wireless communication pod. This wireless communication pod, which provides communication only to the anesthesia system, is provided in the docking device. For example, in one embodiment, a wireless communication "pod" is connected to a "pitot" type flow sensor.
非循环呼吸回路non-circulating breathing circuit
在一个可选的实施方式中，本发明的麻醉系统提供了用于患者的非循环呼吸回路。大多数当前的麻醉系统采用“循环回路”，其包括CO2吸收剂，用于将一些量的呼吸气再回收，接着将其输送回患者。常规麻醉系统还通常使用“混合器”，其混合氧气、空气和氮气，之后作为“新鲜气体”引入循环回路。In an alternative embodiment, the anesthesia system of the present invention provides a non-circulating breathing circuit for the patient. Most current anesthesia systems employ a "circulatory loop" that includes aCO2 absorber to recycle some volume of breathing gas, which is then delivered back to the patient. Conventional anesthesia systems also typically use a "mixer" that mixes oxygen, air and nitrogen before introducing it into the circulation loop as "fresh gas".
图13A示出了常规循环呼吸回路的一些基本元件，指示在本发明的非循环呼吸回路中哪个主要元件被取消或者不需要。在本发明所提供的非循环呼吸回路中取消了吸收器元件1302和风箱1304。此外，用于图13A中所示的回路中的止回阀还被替换为主动阀门，例如在普通的流动阀控制ICU呼吸机中所使用的。Figure 13A shows some basic elements of a conventional cycle breathing circuit, indicating which major elements are eliminated or not required in the non-cycle breathing circuit of the present invention. The absorber element 1302 and bellows 1304 are eliminated in the non-recirculating breathing circuit provided by the present invention. In addition, the check valves used in the circuit shown in FIG. 13A are also replaced with active valves, such as those used in common flow valve controlled ICU ventilators.
图13B示出了根据本发明的实施方式的非循环呼吸回路1300。如图所示，经由吸入阀1308注入的新鲜气体与注入的制剂1312混合，输送至患者1310且接着经由呼出阀1314排出。在一个实施方式中，新鲜气体可以是氧气或空气，因此仅要求用于进气的单个控制阀。在另一个实施方式中，进气阀1308包括被设计成将氧气、空气和一氧化二氮直接混合进入回路的多个控制阀。在一个实施方式中，新鲜气体的源可以是高压管道或者气瓶供应，且吸气阀1308的功能可通过比例电磁阀完成，例如用于常规ICU呼吸机的那些。可选地，可使用诸如室内空气或者氧浓缩器的低压新鲜气体源，且可通过使用涡轮或活塞装置来产生必要的患者回路压力而实现进气阀1308功能。Figure 13B shows a non-recirculating breathing circuit 1300 in accordance with an embodiment of the invention. As shown, fresh gas infused through inhalation valve 1308 mixes with infused formulation 1312 , delivered to patient 1310 and then expelled through exhalation valve 1314 . In one embodiment, the fresh gas may be oxygen or air, thus requiring only a single control valve for intake. In another embodiment, the intake valve 1308 includes multiple control valves designed to mix oxygen, air, and nitrous oxide directly into the circuit. In one embodiment, the source of fresh gas may be a high pressure line or cylinder supply, and the function of the inspiratory valve 1308 may be performed by a proportional solenoid valve, such as those used in conventional ICU ventilators. Alternatively, a low pressure fresh gas source such as room air or an oxygen concentrator can be used, and the inlet valve 1308 function can be achieved by using a turbine or piston arrangement to generate the necessary patient circuit pressure.
在一个实施方式中，由于非循环回路不使经由吸入阀提供气体被重呼吸，所以注入制剂装置1312使用气态麻醉制剂且被设计成将制剂的注入控制为仅被输送至患者的肺部的气体部分。在可选的实施方式中，该制剂按液体计量，且通过呼吸回路管1306的吸入部分的芯配置而蒸发进入气体流。In one embodiment, the infusion agent device 1312 uses a gaseous anesthetic agent and is designed to control the infusion of the agent to only the gas that is delivered to the lungs of the patient since the non-circulatory circuit does not allow the gas provided via the inhalation valve to be rebreathed. part. In an alternative embodiment, the formulation is metered as a liquid and is vaporized into the gas stream through the wick configuration of the inhalation portion of the breathing circuit tubing 1306 .
使用非循环呼吸回路1300，可将麻醉气体的脉冲序列实时地注入患者的吸入流体流中。该目标是将制剂的脉冲序列“调整相位”，从而要求的脉冲部分落在患者的肺部中，而无效区(dead-space)不接收制剂。根据本发明的实施方式，将制剂使用最小化的可选技术是形成麻醉气体脉冲，从而无效区不接收制剂。通常地，无效区包括大约呼吸量的20％。在吸入的末端，无效区灌注有新鲜气体；将制剂的脉冲序列“调整相位”可有助于保证该结尾气体不含有麻醉制剂。Using the non-recirculating breathing circuit 1300, a pulse train of anesthetic gas can be injected into the patient's inspiratory fluid flow in real time. The goal is to "phase" the pulse train of the agent so that the desired portion of the pulse falls in the patient's lungs, while the dead-space does not receive the agent. According to an embodiment of the present invention, an alternative technique to minimize agent usage is to create pulses of anesthetic gas such that the dead zone does not receive agent. Typically, the dead zone includes approximately 20% of the respiratory volume. At the end of the inhalation, the dead zone is perfused with fresh gas; "phasing" the pulse train of agents can help to ensure that this ending gas is free of anesthetic agent.
此外，由于患者是躺下的，肺的后部分的大部分是被充满的而前部分较未被充满。因此，脉冲1321的优选形状是方形的且朝向端部具有一锥度，如图13C中所示。在一个实施方式中，使用气体监测器来帮助无效区和脉冲相位调整。因此，可使用患者生成二氧化碳(VCO2)和呼吸末二氧化碳(EtCO2)的体积来确定约等于支气管内管(ETT)的容积的无效区。Furthermore, since the patient is lying down, the posterior portion of the lung is mostly filled while the anterior portion is less filled. Thus, the preferred shape of the pulse 1321 is square with a taper towards the end, as shown in Figure 13C. In one embodiment, a gas monitor is used to aid in dead zone and pulse phasing. Therefore, the patient's volume of generated carbondioxide (VCO2) and end-tidal carbondioxide (EtCO2) can be used to determine a dead zone approximately equal to the volume of the endobronchial tube (ETT).
接着将制剂注入连接至吸入呼吸的输送，且制剂输送的端部被相位调节至投射至进入无效区的吸入气体的量。The agent infusion is then connected to the delivery of the inspiratory breath, and the end of the agent delivery is phased to the amount of inspiratory gas projected into the dead zone.
因此，由于诸如风箱、吸收器、可替换吸收滤罐、混合器和常规蒸发器都被省略，因此本发明的麻醉系统提供了比常规循环呼吸回路更低成本的非循环呼吸系统。此外，通过使用本非循环呼吸回路1300，将碱石灰(或替代物)从环境废物流中移除，且不必须驱动气体(或其它形式能量)，从而由于要求较少的能量来运行回路所以使得用于空气的摆动泵和氧浓缩器不是必要的。因为在本回路中，吸入气体总是清洁的，只要还考虑传染控制，该回路是最优的且易于维护，导致所有者的低成本。此外，还观察到临床医生频繁地将循环回路的稀释效应混淆，从而求助于吸入气体控制(IGC)或排出气体控制(EGC)系统。由于没有稀释效应，因此本非循环呼吸回路1300自动提供IGC。在一个实施方式中，可将吸入阀特征整个地以软件实现，且可实现比常规混合器所提供的高得多的流动。Thus, the anesthesia system of the present invention provides a lower cost non-rebreathing system than conventional rebreathing circuits since elements such as bellows, absorbers, replaceable absorber canisters, mixers and conventional vaporizers are omitted. Furthermore, by using the present non-recirculating breathing circuit 1300, soda lime (or a substitute) is removed from the environmental waste stream and the gas (or other form of energy) does not have to be driven, thereby reducing energy consumption since less energy is required to run the circuit. Oscillating pumps and oxygen concentrators for air are rendered unnecessary. Since in this circuit the suction gas is always clean, this circuit is optimal and easy to maintain as long as infection control is also taken into account, resulting in low costs for the owner. In addition, it has been observed that clinicians frequently confuse the dilution effect of the circulatory circuit and resort to inspiratory gas control (IGC) or exhaust gas control (EGC) systems. The present acyclic breathing circuit 1300 automatically provides IGC since there is no dilution effect. In one embodiment, the suction valve feature can be implemented entirely in software and can achieve much higher flows than conventional mixers provide.
旁路氧气控制和致动Bypass oxygen control and actuation
如本领域已知的，具有电子混合控制的麻醉系统通常还包括紧急旁路阀系统，其在混合器失效的情况下使用户能设置氧气流动。一些现有技术麻醉系统使用专用的针阀以提供旁路功能，而其它的使用专用机械气动开关，以打开旁路阀或者恢复至电子混合器控制。As is known in the art, anesthesia systems with electronic mixing controls also typically include an emergency bypass valve system that enables the user to set the oxygen flow in the event of a mixer failure. Some prior art anesthesia systems use a dedicated needle valve to provide a bypass function, while others use a dedicated mechanical pneumatic switch to open the bypass valve or revert to electronic mixer control.
在一个实施方式中，本发明涉及麻醉输送系统，其包括双位置按钮，该双位置按钮在第一位置与主动电子混合控制对应，且在第二位置与主动紧急旁路阀对应。在第二位置，当紧急旁路阀启动而自电子混合器的流动中断时，双位置按钮“弹起”，且同时地与机械针阀接合。该双位置按钮提供单点氧气调节，其在麻醉系统的电子混合控制失效的情况下以及在用户不知道在麻醉系统中发生这种类型的失效的情况下使用户能快速调节氧气流。此外，通过将双位置按钮推回至第一位置，麻醉系统的该电子混合控制再接合。本发明还在紧急旁路被启动时提供自旁路针阀的预设置的预定量的氧气流，使得在电子混合器控制失效的情况下自动地发生已知量的氧气流，而不要求任何用户交互作用。In one embodiment, the present invention is directed to an anesthesia delivery system that includes a two-position button that corresponds in a first position to an active electronic hybrid control and in a second position to an active emergency bypass valve. In the second position, the two-position button "pops" and simultaneously engages the mechanical needle valve when the emergency bypass valve is activated interrupting flow from the electronic mixer. This two position button provides a single point oxygen adjustment which enables the user to quickly adjust the oxygen flow in the event of a failure of the anesthesia system's electronic mixing control and in the event the user is unaware that this type of failure has occurred in the anesthesia system. Additionally, the electronic hybrid control of the anesthesia system is re-engaged by pushing the two-position button back to the first position. The present invention also provides a pre-set predetermined amount of oxygen flow from the bypass needle valve when the emergency bypass is activated so that in the event of electronic mixer control failure a known amount of oxygen flow occurs automatically without requiring any User interaction.
图14A示出了根据本发明的实施方式的麻醉系统的旁路致动按钮1406的第一位置。该麻醉系统包括气体控制按钮1402、1404和双位置旁路致动按钮1406。该按钮1402、1404和1406与电子编码器(未在图14A中示出)接合，且用于电子地控制在麻醉系统中的气流速度。在麻醉系统中的气体流动图像地显示在电子屏幕1408上，且经过浮动球式流量计1410。如图14A中所示，旁路致动双位置按钮1406处于与麻醉系统的侧表面平齐的第一位置，表示接合麻醉系统的电子混合控制。FIG. 14A illustrates a first position of a bypass actuation button 1406 of an anesthesia system in accordance with an embodiment of the present invention. The anesthesia system includes gas control buttons 1402 , 1404 and a two-position bypass activation button 1406 . The buttons 1402, 1404 and 1406 interface with electronic encoders (not shown in Figure 14A) and are used to electronically control the airflow rate in the anesthesia system. Gas flow in the anesthesia system is graphically displayed on an electronic screen 1408 and passes through a floating ball flow meter 1410 . As shown in Figure 14A, the bypass actuation two-position button 1406 is in a first position flush with the side surface of the anesthesia system, representing engagement of the electronic hybrid controls of the anesthesia system.
图14B示出了根据本发明的实施方式的麻醉系统的旁路致动按钮1406的第二位置。如图14B中所示，旁路致动双位置按钮1406处于第二“弹出”致动位置，指示在麻醉系统中的启动的紧急氧气旁路功能。在该启动位置，按钮1406与直接控制氧气流动的针阀(图14B中未示出)直接接合，旁路通过麻醉系统的电子混合器控制。Figure 14B shows a second position of the bypass actuation button 1406 of the anesthesia system in accordance with an embodiment of the present invention. As shown in Figure 14B, bypass actuation two-position button 1406 is in a second "pop-up" actuation position, indicating an activated emergency oxygen bypass function in the anesthesia system. In this activated position, button 1406 directly engages a needle valve (not shown in FIG. 14B ) that directly controls oxygen flow, bypassing control by the electronic mixer of the anesthesia system.
图14C示出了根据本发明的实施方式的用户调节麻醉系统的旁路致动按钮1406。如图14C中所示，用户1412可通过根据图像地显示在电子屏幕1408上的氧气流而手动地调节旁路致动双位置按钮1406，从而调节麻醉系统中的氧气流。因此，本发明使用户能通过观察流动值的图像显示1408而调节旁路氧气流。此外，浮动球式流量计1410还记录提供至患者的所有气流。Figure 14C illustrates user adjustment of the bypass actuation button 1406 of the anesthesia system, in accordance with an embodiment of the present invention. As shown in FIG. 14C , the user 1412 can adjust the oxygen flow in the anesthesia system by manually adjusting the bypass actuation two-position button 1406 according to the oxygen flow graphically displayed on the electronic screen 1408 . Thus, the present invention enables the user to adjust the bypass oxygen flow by viewing the graphical display 1408 of flow values. In addition, the floating ball flow meter 1410 also records all airflow provided to the patient.
图14D示出了根据本发明的实施方式，即使在麻醉系统处于“关闭”状态时该麻醉系统的启动旁路致动按钮1406。在一个实施方式中，即使当麻醉系统的电子设备处于模拟电子失效的状态时，旁路致动双位置按钮1406也保持在图14D中所示的启动状态且使得氧气的连续流动被输送至患者。在该情况下，通过观察在浮动球式流量计1410上的流值的表示，可手动地调节氧气的流动。Figure 14D illustrates the activation bypass actuation button 1406 of the anesthesia system even when the anesthesia system is in the "OFF" state, in accordance with an embodiment of the present invention. In one embodiment, even when the electronics of the anesthesia system are in a state that simulates an electronic failure, the bypass actuation two-position button 1406 remains in the activated state shown in Figure 14D and allows a continuous flow of oxygen to be delivered to the patient . In this case, by observing the indication of the flow value on the floating ball flow meter 1410, the flow of oxygen can be adjusted manually.
ACGO翻转选择器(flip-up selector)ACGO flip-up selector (flip-up selector)
常规的麻醉系统通常装备有辅助共用气体出口(ACGO)，其让混合的“新鲜气体流”(FGF)从循环系统被转移至外部回路，该外部回路通常是非再呼吸式麻醉系统。在现有技术的麻醉系统中，该ACGO通常是水平22mm的端口，其经由设置在用户界面上的机械杆或者电子控制而启动。现有技术的麻醉系统不提供对启动ACGO的清楚指示，从而在一些情况下对关于ACGO是否启动引起混淆，甚至引起ACGO被用户无意地启动。Conventional anesthesia systems are usually equipped with an auxiliary common gas outlet (ACGO) that allows a mixed "fresh gas flow" (FGF) to be diverted from the circulatory system to an external circuit, usually a non-rebreathing anesthesia system. In prior art anesthesia systems, the ACGO is typically a horizontal 22mm port that is activated via a mechanical lever placed on the user interface or an electronic control. Prior art anesthesia systems do not provide clear indications to activate ACGO, thereby causing confusion as to whether ACGO is activated in some cases, or even causing ACGO to be activated unintentionally by the user.
在一个实施方式中，本发明涉及麻醉输送系统，其提供ACGO作为22mm端口，使得该端口本身可用于启动。在一个实施方式中，通过将该端口向下旋转，使得该端口竖直地设置，且端口开口朝向地面且其平面与地面平行，从而关闭该ACGO。该定位显著地降低了ACGO端口被用户错误地处理为新鲜气流的源的机会。在该位置，FGF被自动地引至系统的循环呼吸回路中的内部新鲜气体流动端口。该ACGO通过将端口向上旋转90度，使得端口水平地设置，且端口开口朝向用户且其平面与地面垂直，从而启动。该定位让管连接至端口。在一个实施方式中，ACGO端口被设置为双稳定开关，其被向上或向下转动而分别对应启动或停用状态。该端口不能被设置在中间状态。此外，在一个实施方式中，本发明的信息投射灯特征结合至AGCO端口，当端口向上且启动时将其以绿色脉冲灯照亮。In one embodiment, the present invention relates to an anesthesia delivery system that provides ACGO as a 22mm port so that the port itself can be used for priming. In one embodiment, the ACGO is closed by rotating the port downward so that the port is positioned vertically with the port opening facing the ground and its plane parallel to the ground. This positioning significantly reduces the chance of the ACGO port being mishandled by the user as a source of fresh gas flow. In this position, FGF is automatically directed to the internal fresh gas flow port in the system's rebreathing circuit. The ACGO is activated by rotating the port upwards 90 degrees so that the port is positioned horizontally with the port opening facing the user and its plane perpendicular to the ground. This positioning allows the tubing to connect to the port. In one embodiment, the ACGO port is configured as a bistable switch that is turned up or down to correspond to an activated or deactivated state, respectively. The port cannot be set in an intermediate state. Additionally, in one embodiment, the information projection light feature of the present invention is incorporated into the AGCO port, illuminating it with a green pulsing light when the port is up and activated.
图15A示出了根据本发明的实施方式的麻醉系统1500的辅助共用气体出口(ACGO)端口1502。图15B示出了根据本发明的实施方式的麻醉系统1500的辅助共用气体出口(ACGO)端口1502的停用位置。如图所示，该ACGO 1502在转动为竖直向下时处于停用状态。图15C示出了根据本发明的实施方式的麻醉系统1500的辅助共用气体出口(ACGO)端口1502的启动位置。如图15C中所示，该ACGO 1502在向上转动至水平位置时处于启动状态。当该ACGO端口1502被启动时，来自麻醉系统1500的气体混合系统的新鲜气体从ACGO端口1502流出。Figure 15A illustrates an auxiliary common gas outlet (ACGO) port 1502 of an anesthesia system 1500 in accordance with an embodiment of the invention. Figure 15B illustrates an inactive position of the auxiliary common gas outlet (ACGO) port 1502 of the anesthesia system 1500 in accordance with an embodiment of the invention. As shown, the ACGO 1502 is inactive when rotated straight down. Figure 15C illustrates the activated position of the auxiliary common gas outlet (ACGO) port 1502 of the anesthesia system 1500 in accordance with an embodiment of the invention. As shown in Figure 15C, the ACGO 1502 is activated when rotated upward to the horizontal position. When the ACGO port 1502 is activated, fresh gas from the gas mixing system of the anesthesia system 1500 flows out of the ACGO port 1502 .
图15D示出了根据本发明的实施方式的连接有呼吸回路的辅助共用气体出口(ACGO)端口的启动位置。如图15D所示，当端口1502处于启动水平位置时，呼吸回路1504可连接至AGCO端口1502。在一个实施方式中，该呼吸回路1504用于让手动换气患者(为了清楚没有示出袋)使用来自ACGO端口1502的新鲜气体流。在一个实施方式中，处于启动向上水平位置的ACGO端口1502可支持5lb呼吸回路的载荷。Figure 15D shows an activated position of an auxiliary common gas outlet (ACGO) port connected to a breathing circuit in accordance with an embodiment of the present invention. As shown in Figure 15D, breathing circuit 1504 may be connected to AGCO port 1502 when port 1502 is in the actuated horizontal position. In one embodiment, the breathing circuit 1504 is used to manually ventilate a patient (bag not shown for clarity) using a flow of fresh gas from the ACGO port 1502 . In one embodiment, the ACGO port 1502 in the activated upward horizontal position can support a 5 lb breathing circuit load.
电子蒸发Evaporation
当前的麻醉蒸发器系统包括阀和/或灯芯式系统，用于将液体麻醉制剂转换为气体形式。通常，这些系统提供的气体的制剂浓度水平为0-10％(对于Suprane尽管有时更高)，该气体用作循环呼吸系统中的“新鲜气体”或“补偿”气体。当前的装置是复杂的，且要求精确的机械部件或流动控制系统进行操作，形成较高成本的装置。在受让给LouisGibeck AB的专利号为6,155,255的美国专利中说明了新的蒸发器元件类型，其使用直接液体注射至低成本“灯芯式”配置。Current anesthetic vaporizer systems include valve and/or wick systems for converting liquid anesthetic agents into gaseous form. Typically, these systems provide a formulation concentration level of 0-10% (although sometimes higher for Suprane) gas that is used as the "fresh gas" or "make-up" gas in the rebreathing system. Current devices are complex and require precise mechanical components or flow control systems to operate, resulting in relatively high cost devices. A new type of evaporator element is described in US Patent No. 6,155,255 assigned to Louis Gibeck AB, which uses direct liquid injection into a low cost "wick" configuration.
本发明提供了将与美国专利第6,155,255号中说明的相似的蒸发器元件结合至麻醉系统作为电子蒸发器进行实际使用的方法。在一个实施方式中，使用微压电泵来泵送待蒸发的液体。在将液体提供至蒸发器的供应管线中测量液体注射，并且使用反馈回路完成控制。流入蒸发器(芯式)中的液体的测量和进入或排出蒸发器(区别为麻醉蒸气)的气体流的测量用于确定麻醉制剂的浓度。执行该步骤以替代或者结合在患者处的麻醉制剂浓度测量。此外，可执行与通过蒸发器的气体流改变相结合的液体流的脉冲(即，增大或减小)。将蒸发器设置在非循环呼吸回路麻醉系统的主流动流中，例如在前面部分中所说明的。控制流体流入蒸发器的控制单元连接至麻醉系统的显示器，将蒸发器子系统集成为本发明的较宽麻醉系统的部件。The present invention provides a method of incorporating a vaporizer element similar to that described in US Patent No. 6,155,255 into an anesthesia system for practical use as an electronic vaporizer. In one embodiment, a micro piezoelectric pump is used to pump the liquid to be evaporated. Liquid injection is measured in the supply line that provides liquid to the evaporator, and control is done using a feedback loop. The measurement of the liquid flow into the vaporizer (wick) and the gas flow into or out of the vaporizer (distinctively anesthetic vapour) is used to determine the concentration of the anesthetic agent. This step is performed instead of or in conjunction with the measurement of the concentration of the anesthetic agent at the patient. Furthermore, pulsing (ie, increasing or decreasing) of liquid flow combined with a change in gas flow through the evaporator may be performed. Place the vaporizer in the main flow stream of the non-recirculating breathing circuit anesthesia system, such as described in the previous section. The control unit controlling the flow of fluid into the vaporizer is connected to the display of the anesthesia system, integrating the vaporizer subsystem as part of the broader anesthesia system of the present invention.
在一个实施方式中，将阀增加至已知的与美国专利第6,155,255号中说明的相似的电子蒸发器，且被控制以提供蒸发器的直接气体流旁路(immediate gas flow bypass)。这用于系统的氧气涌流(oxygen flush)或者用于将蒸发器立即关闭。该旁路的比例控制还可用于将增加的蒸气的量快速减少而不会完全地停止蒸气增加，如完全旁路的情况。此外，新鲜气体流(如，氧气)的组分可选择性地通过蒸发器，以获得麻醉制剂蒸气的一致摄取。在一个实施方式中，液体类型的制剂检测装置被增加至连接至液体麻醉的外部容器(液体麻醉从其中被泵送至蒸发器)的泵或者该容器本身，以确定麻醉类型。此外，容器可包括多个储存器，通过泵控制单元控制每一个储存器的操作，从而允许多种麻醉制剂类型被提供在单个麻醉机器中。容纳麻醉制剂的储存器可被冷却以将麻醉制剂保持为液体形式以通过连接至蒸发器的泵的液体注射装置进行注射。在多种实施方式中，使用多种保护和消除液体气穴装置。该装置的示例包括：冷却一个或多个泵以防止在麻醉液体泵送经过系统时的气穴；将麻醉制剂储存器压至连接的泵以防止气穴；在泵或将储存器连接至泵的供应管中使用气穴检测装置；在供应管或泵中使用具体已知的设计特征以防止气穴；且，向供应管增加阻力，从而形成反压力以防止气穴。In one embodiment, a valve is added to a known electronic vaporizer similar to that described in US Patent No. 6,155,255 and is controlled to provide an immediate gas flow bypass of the vaporizer. This is used for the oxygen flush of the system or to shut down the vaporizer immediately. This proportional control of the bypass can also be used to quickly reduce the amount of added vapor without completely stopping the vapor increase, as would be the case with a full bypass. In addition, components of the fresh gas stream (eg, oxygen) can be selectively passed through the vaporizer to achieve consistent uptake of the anesthetic agent vapor. In one embodiment, a liquid type agent detection device is added to the pump connected to the external container of liquid anesthesia from which it is pumped to the vaporizer or the container itself to determine the type of anesthesia. Furthermore, the container may comprise multiple reservoirs, the operation of each reservoir being controlled by the pump control unit, thereby allowing multiple anesthetic agent types to be provided in a single anesthesia machine. The reservoir containing the anesthetic agent may be cooled to maintain the anesthetic agent in liquid form for injection by the liquid injection device of the pump connected to the vaporizer. In various embodiments, various protection and liquid cavitation elimination devices are used. Examples of such devices include: cooling one or more pumps to prevent cavitation when anesthetic fluid is pumped through the system; pressing a reservoir of anesthetic agent to a connected pump to prevent cavitation; use a cavitation detection device in the supply pipe; use specifically known design features in the supply pipe or pump to prevent cavitation; and, add resistance to the supply pipe, thereby creating a back pressure to prevent cavitation.
在一个实施方式中，本发明允许根据新鲜气体流选择不同的蒸发器尺寸。例如，麻醉控制装置(例如按钮或开关)可根据使用的新鲜气流的量而选择高流动或低流动蒸发器。此外，在麻醉制剂供应管中可使用开/关阀作为安全控制以立即停止向蒸发器的液体注射。在一个实施方式中，将传感器元件设置在患者气道以读取在不同的光波长患者吸入的气体的光学吸收，且在该点感应到的信号用于通过将蒸发器作为麻醉器的子系统而进行吸入气体控制或者呼出气体控制。此外，在一个实施方式中，使用串联的两个液体流动传感器从而以足够的精确度感应全范围的液体流动速度，其中一个液体流动传感器用于高流速而另一个用于低流速。In one embodiment, the invention allows selection of different evaporator sizes depending on the fresh gas flow. For example, an anesthesia control device such as a button or switch may select a high flow or low flow vaporizer depending on the amount of fresh gas flow being used. In addition, an on/off valve can be used in the anesthetic agent supply line as a safety control to immediately stop the injection of liquid to the vaporizer. In one embodiment, a sensor element is placed in the patient's airway to read the optical absorption of gas inhaled by the patient at different wavelengths of light, and the signal sensed at this point is used to Instead, inspiratory gas control or exhaled gas control is performed. Furthermore, in one embodiment, two liquid flow sensors are used in series to sense the full range of liquid flow velocities with sufficient accuracy, one for high flow velocities and the other for low flow velocities.
上述示例仅仅示出了本发明的系统的很多应用。尽管这里仅说明了本发明的几个实施方式，然而应该理解本发明可实现为很多其它具体形式而不偏离本发明的实质和范围。因此，本示例和实施方式被考虑为示例性的而不是限制性的，且可在所附权利要求的范围内对本发明进行修改。The above examples merely illustrate the many applications of the system of the present invention. Although only a few embodiments of the invention have been described herein, it should be understood that the invention may be embodied in many other specific forms without departing from the spirit and scope of the invention. Accordingly, the examples and embodiments are to be considered as illustrative and not restrictive, and modifications of the invention may be made within the scope of the appended claims.
