新型内窥镜面罩New Endoscopic Mask

技术领域technical field

本发明涉及一种为病人做手术、医用检查或宫腔镜检查用的新型内窥镜面罩，具体涉及一种可与呼吸机、麻醉机或呼吸镇痛装置相配套使用的新型内镜面罩。The invention relates to a new type of endoscopic mask for patients in operation, medical examination or hysteroscopic examination, in particular to a new type of endoscopic mask which can be matched with ventilator, anesthesia machine or breathing analgesic device.

背景技术Background technique

目前医疗行业中，在给病人做手术、医用检查或宫腔镜检查时，多使用呼吸机、麻醉机或呼吸镇痛装置来辅助治疗或检查。在给病人输送氧气或麻醉气体的过程中，内镜面罩被广泛使用。现市面上，内镜面罩品种较多，但在结构上普遍都存在以下缺点：At present, in the medical industry, ventilators, anesthesia machines or respiratory analgesia devices are often used to assist treatment or examination when performing operations, medical examinations or hysteroscopy on patients. Endoscopic masks are widely used during the delivery of oxygen or anesthetic gases to patients. There are many types of endoscopic masks on the market, but they generally have the following disadvantages in structure:

只有新鲜气体入口而没有病人废气排出口，不利于保持输入新鲜气体的清洁度，易引起呼吸道污染；尺寸不合理，较小，在病人张嘴接受呼吸插管或腔镜插管的情况下，面部会受到面罩的压迫，感到不适，甚至会堵塞呼吸道，危害病人的生命安全；没有专设的呼吸插管或腔镜插管插入口，在使用插管时只能用鼻罩替代，增加了检查或手术的风险，也增加了资源浪费；没有设病人呕吐物排出口，无法排出病人因插管引起的呕吐废物，即增加了病人的风险也增加了医护人员接触医疗废物的风险。There is only fresh gas inlet and no patient exhaust gas outlet, which is not conducive to maintaining the cleanliness of the input fresh gas, and may easily cause respiratory pollution; the size is unreasonable and small, and when the patient opens his mouth to accept respiratory intubation or laparoscopic intubation, the face The body will be oppressed by the mask, feel uncomfortable, and even block the respiratory tract, endangering the patient's life safety; there is no special breathing intubation or endoscopic intubation port, and the nasal mask can only be used instead when using the intubation, which increases the inspection. It also increases the waste of resources; there is no discharge port for patient vomitus, and it is impossible to discharge the vomit waste caused by intubation, which increases the risk of patients and increases the risk of medical staff contacting medical waste.

专利号为200820062284.7、名称为《无痛胃镜专用面罩》的中国实用新型专利中，公开了一种无痛胃镜专用面罩，包含面罩主体、面罩固定结构、Y形管接口、吸引孔和胃镜置入孔。此面罩能够实现在实施人工控制或辅助呼吸的同时，又能进行胃镜检查。In the Chinese utility model patent No. 200820062284.7, named "Special Mask for Painless Gastroscopy", a special mask for painless gastroscopy is disclosed, which includes the main body of the mask, the fixing structure of the mask, the Y-shaped tube interface, the suction hole and the insertion of the gastroscope. hole. The mask can realize gastroscopic examination while performing artificial control or assisted breathing.

但是，该专利中与呼吸功能有关的仍然只有一个Y形管接口，相当于只有新鲜气体入口而没有病人废气排出口。虽然Y形管本身有空气出口，但多增加的Y形管会形成空气滞留，造成呼吸时有效换气量降低。而且，该专利中的胃镜置入孔中如果没有胃镜置入的话，就形成对大气的连通，使得Y形管或与其配套的呼吸机无法使用。However, there is still only one Y-shaped pipe interface related to the breathing function in this patent, which is equivalent to having only fresh gas inlets and no patient exhaust gas outlet. Although the Y-shaped tube itself has an air outlet, the additional Y-shaped tubes will form air retention, resulting in a decrease in effective ventilation during breathing. Moreover, if there is no gastroscope inserted in the gastroscope insertion hole in this patent, it will form a connection to the atmosphere, so that the Y-shaped tube or its matching ventilator cannot be used.

具体实施方式Detailed ways

如图1～3所示，本实施例主要由以下部件组成：面罩壳1、密封塞2、贴面软垫3、新鲜气体入口13、病人呼气出口14、引流口11、插管口12、密封塞主座21、插管口塞22、引流口塞23，在新鲜气体入口13和病人呼气出口14中分别有片状单向阀瓣4。As shown in Figures 1 to 3, this embodiment is mainly composed of the following components:mask shell 1, sealing plug 2,veneer cushion 3,fresh gas inlet 13,patient exhalation outlet 14, drainage port 11, intubation port 12 , sealing plugmain seat 21,intubation port plug 22, drainage port plug 23, infresh gas inlet 13 andpatient exhalation outlet 14, sheet-shaped one-way valve disc 4 is arranged respectively.

本内镜面罩的面罩壳1上共设计有4个孔口，分别为：①引流口11，用于病人呕吐物的吸出以保持面罩的清洁；②插管口12，用于医用插管的插入；③气体入口13，用于麻醉气体或新鲜空气或氧气的输入，④病人呼气出口14，用于病人呼出气体的排出，并且在新鲜气体入口13和病人呼气出口14中装有片状单向阀瓣4以防止麻醉气体(或新鲜空气或氧气)的流出。面罩壳1下部装有贴面软垫2，贴面软垫根据人面部轮廓进行设计，采用双层软膜结构，由柔软、高弹性的硅胶制成，能紧贴面部，密封性高，佩戴方便舒适，且可拆卸，进行高温清洗消毒。A total of 4 openings are designed on themask shell 1 of the endoscopic mask, which are: ① drainage port 11, which is used to suck out the patient's vomit to keep the mask clean; ② intubation port 12, which is used for medical intubation. Insert; ③gas inlet 13, for the input of anesthesia gas or fresh air or oxygen, ④patient exhalation outlet 14, for the discharge of patient's exhalation gas, and infresh gas inlet 13 andpatient exhalation outlet 14, sheet is housed Shaped one-way valve disc 4 to prevent the outflow of anesthesia gas (or fresh air or oxygen). The lower part of themask shell 1 is equipped with a veneer cushion 2. The veneer cushion is designed according to the contour of the human face. It adopts a double-layer soft film structure and is made of soft and highly elastic silica gel. Convenient and comfortable, and detachable for high-temperature cleaning and disinfection.

另外，如图2，本面罩还设计有密封塞2，其包括3个部分：①密封塞主座21，用于配合面罩壳1进行装配并设计有孔口用于医用插管的插入；②插管口塞22，用于封堵密封塞主座上的插管口；③引流口塞23，用于封堵引流口。在本面罩不用于医用检查时，可用插管口塞及引流口塞分别将插管口及引流口密封，便可作普通麻醉面罩或普通呼吸面罩实用。In addition, as shown in Figure 2, the mask is also designed with a sealing plug 2, which includes 3 parts: ① themain seat 21 of the sealing plug is used for assembling with themask shell 1 and is designed with an orifice for the insertion of a medical intubation tube; ② Theintubation port plug 22 is used to block the intubation port on the main seat of the sealing plug; 3. the drainage port plug 23 is used to block the drainage port. When the face mask is not used for medical examination, the intubation port and the drainage port can be sealed by using the intubation port plug and the drainage port plug respectively, so that it can be used as an ordinary anesthesia mask or an ordinary breathing mask and is practical.

由于病人在做通过口部的内镜检查手术时，需张开口部插入内镜检查管，增大了面部长度，现有面罩长度依病人闭口时的长度所设计，无法做到更好的密封。本实施例的面罩总长不小于150mm，比现有面罩长至少长20mm，能更好的贴合面部进行密封，即使病人完全把嘴张开时，都不会被面罩压迫到。Because the patient needs to open the mouth to insert the endoscopic examination tube during the endoscopic examination operation through the mouth, which increases the length of the face. The length of the existing mask is designed according to the length of the patient's closed mouth, which cannot achieve a better seal . The total length of the mask of this embodiment is not less than 150mm, which is at least 20mm longer than the existing mask, and can better fit the face for sealing. Even when the patient fully opens his mouth, he will not be pressed by the mask.

由于本实施例在面罩壳1上直接设计有新鲜气体入口、病人呼气出口和引流口，加上安装在面罩壳上密封塞上的插管孔，可同时实现经口部的内镜检查和正压通气，并排出病人的呼出气体和经口部做内镜检查时可能产生的排出物。Because the present embodiment is directly designed with fresh gas inlet, patient's exhalation outlet and drainage port onmask shell 1, adds the intubation hole that is installed on the sealing plug on the mask shell, can realize the endoscopic examination and examination through oral cavity simultaneously. Positive pressure ventilation, and expulsion of the patient's exhaled air and possible discharge during oral endoscopy.

由于在做内镜检查时，病人一般采用左侧位卧躺在手术床上，故将新鲜气体入口设计在面罩上部偏左位置以方便接管，同时此位置靠近病人的鼻子，通过外接的单向阀使新鲜气体导入面罩，使病人很容易吸入新鲜气体，如图4a、4b。During the endoscopic examination, the patient generally lies on the left side on the operating bed, so the fresh gas inlet is designed on the left side of the upper part of the mask to facilitate the connection. The fresh gas is introduced into the mask, so that the patient can easily inhale the fresh gas, as shown in Fig. 4a, 4b.

由于在做内镜检查时，病人一般采用左侧位卧躺在手术床上，将病人呼气出口设计在面罩的左下侧，该位置放在病人鼻子的下端，使病人呼出气很直接容易的排出面罩体，同时病人呼气出口同新鲜气体入口距离不小于50mm，并且装有片状单向阀瓣4，如图5，可防止病人呼出气倒流入面罩同新鲜气体混合。During the endoscopic examination, the patient generally lies on the left side on the operating bed, and the patient's exhalation outlet is designed on the lower left side of the mask, which is placed at the lower end of the patient's nose, so that the patient's exhaled air can be directly and easily discharged The mask body, meanwhile, the distance between the patient's exhalation outlet and the fresh gas inlet is not less than 50mm, and a sheet-shaped one-way valve flap 4 is installed, as shown in Figure 5, which can prevent the patient's exhaled air from flowing back into the mask and mixing with fresh air.

由于在做内镜检查时，病人一般采用左侧位卧躺在手术床上，且病人多会产生经口部的液态或固液混合态排泻物，故在面罩的右下侧设计有引流口，可方便液态或固液混合态排泻物流向引流口并抽引出面罩内部。During the endoscopic examination, the patient usually lies on the left side on the operating bed, and the patient often produces liquid or solid-liquid mixed excretion through the mouth, so a drainage port is designed on the lower right side of the mask. , which can facilitate liquid or solid-liquid mixed excrement to flow to the drainage port and be drawn out of the mask.

本实施例的贴面软垫设计，如图6、7，具体涉及：The veneer cushion design of the present embodiment, as shown in Figures 6 and 7, specifically relates to:

采用人体工学设计，其造型曲线和双层软膜结构可很舒适地贴合住病人的面部，并且密封性良好；采用可拆卸的卡入槽设计，利用软垫的弹性变形可很方便从塑胶材料的面罩壳上卡装和拆卸，当软垫发生人为损破或使用时间长变形及发黄时只需将软垫更换，而现有的内镜检查专用面罩如贴面的软垫发生人为损破或使用时间长变形及发黄则必须将面罩整体更换。Ergonomically designed, its shape curve and double-layer soft film structure can fit the patient's face comfortably, and the seal is good; it adopts a detachable snap-in slot design, and it is easy to remove from the plastic by using the elastic deformation of the soft cushion. When the soft cushion is artificially damaged or deformed and yellowed after a long time of use, the soft cushion only needs to be replaced, while the existing special masks for endoscopic examination, such as veneered cushions, are artificially damaged. If it is damaged or deformed and yellowed after long-term use, the mask must be replaced as a whole.

本实施例的密封塞设计，如图8，该密封塞使用弹性好的硅胶材料，包括主体21、插管口塞22、引流口塞23和用于联接主体和2个孔塞的细长筋条24。主体21设计有卡槽并通过自身的弹性变形卡在面罩壳上，如图2；该密封塞的另一特点在于在主体中间除了设有传统面罩所有的内镜检查用的插管孔外，在在不做内镜检查时可直接用密封塞所带的插管口塞22和引流口塞23通过弹性变形分别插在自身插管孔和面罩壳上引流孔形成密封，如图2，在不做内镜检查时也可实现面罩的正压通气而不会泄漏气体，其一体化设计以及和面罩壳装配后后形成一个有机的组合体方便了医生的操作，也避免了现有面罩单独设计和安装插管塞和引流管塞的操作不便以及零件易丢失的缺点。The design of the sealing plug in this embodiment is shown in Figure 8. The sealing plug is made of silicone material with good elasticity, including amain body 21, anintubation port plug 22, a drainage port plug 23 and an elongated rib for connecting the main body and two hole plugs.Article 24. Themain body 21 is designed with a card slot and is stuck on the mask shell through its own elastic deformation, as shown in Figure 2; another feature of the sealing plug is that in addition to the intubation hole for endoscopic examination that is provided with all traditional masks in the middle of the main body, When not doing endoscopic examination, theintubation port plug 22 and the drainage port plug 23 of the sealing plug can be directly inserted into the intubation hole and the drainage hole on the mask shell to form a seal through elastic deformation, as shown in Figure 2. Positive pressure ventilation of the mask can be achieved without endoscopic examination without gas leakage. Its integrated design and the formation of an organic combination with the mask shell after assembly facilitates the doctor's operation and avoids the need for existing masks. The design and installation of intubation plugs and drainage tube plugs are inconvenient and the parts are easily lost.

本面罩的材料设计，其中面罩壳使用可以通过高温消毒或环氧己琓消毒的塑胶材料包括PC、PSU或PPSU材料，密封塞和贴面软垫使用可以通过高温消毒或环氧己琓消毒的软胶材料包括硅胶材料，使得本面罩可以通过高温消毒或环氧己琓消毒来重复使用，而传统的使用于内镜检查的面罩多为一次性使用。The material design of the mask, wherein the mask shell uses plastic materials that can be sterilized by high temperature or epoxy resin, including PC, PSU or PPSU materials, and the sealing plug and veneer cushion use plastic materials that can be sterilized by high temperature or epoxy resin The soft rubber material includes silica gel material, so that the mask can be reused through high-temperature disinfection or epoxy epoxy disinfection, while traditional masks used for endoscopic examination are mostly disposable.

以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be assumed that the specific implementation of the present invention is limited to these descriptions. For those of ordinary skill in the technical field of the present invention, without departing from the concept of the present invention, some simple deduction or replacement can be made, which should be regarded as belonging to the protection scope of the present invention.
