技术领域technical field
本发明涉及医疗器械技术领域，尤其涉及一种视像远端容纳组件及具有其的喉罩主体、喉罩。The invention relates to the technical field of medical instruments, in particular to a video distal receiving component, a laryngeal mask main body and a laryngeal mask.
背景技术Background technique
喉罩作为一种声门上通气装置，属于人工呼吸道，自1983年被发明后，因其操作简便、成功率高、损伤小等优点而广泛应用于临床。喉罩是一种介于面罩和气管插管之间的人工气道装置，既可以让患者保持自主呼吸，亦可实施正压通气。As a supraglottic ventilation device, the laryngeal mask belongs to the artificial airway. Since it was invented in 1983, it has been widely used in clinics because of its advantages of simple operation, high success rate, and less damage. The laryngeal mask is an artificial airway device between the mask and the endotracheal tube, which can not only keep the patient breathing spontaneously, but also implement positive pressure ventilation.
没有带可视化功能的喉罩一般盲插置入患者体内，由于操作时不能窥及咽喉部细节，操作人员只能凭手感、经验盲插。盲插很有可能导致喉罩放置不准确，位置的不准确可能会导致后续的一系列问题，比如，不能有效隔离呼吸道和消化道，造成喉罩密封不全，漏气，患者胃胀气、返流、甚至误吸；位置的不准确也增大了手术中喉罩移动的可能性。此外，盲插也会增大选用型号不恰当喉罩的几率。当出现上述的一个或多个问题时，操作人员不得不重新调整喉罩角度或者多次反复插入，如此可能会延长操作时间，耽误危重患者的抢救。且多次试插也可能造成患者口腔粘液增多，操作难度随之加大。再者，反复操作容易造成患者咽腔损伤出血，心血管反应大，增加手术风险等。The laryngeal mask without visualization function is generally inserted into the patient's body blindly. Since the details of the throat cannot be seen during operation, the operator can only blindly insert it based on hand feeling and experience. Blind insertion is likely to lead to inaccurate placement of the laryngeal mask, which may lead to a series of subsequent problems, such as inability to effectively isolate the respiratory tract and digestive tract, resulting in incomplete sealing of the laryngeal mask, air leakage, flatulence, and reflux in patients , and even aspiration; the inaccurate position also increases the possibility of movement of the laryngeal mask during the operation. In addition, blind insertion will also increase the chance of choosing an inappropriate type of laryngeal mask. When one or more of the above problems occur, the operator has to readjust the angle of the laryngeal mask or insert it repeatedly, which may prolong the operation time and delay the rescue of critically ill patients. And repeated trial insertion may also cause the patient's oral mucus to increase, and the difficulty of operation will increase accordingly. Furthermore, repeated operations are likely to cause pharyngeal cavity injury and bleeding in patients, increase cardiovascular response, and increase surgical risks.
为了确保喉罩置入位置的准确性，操作人员常通过各种间接手段检查，如观察胸部起伏、肺部顺应性、听诊是否有漏气声、观察颈部隆起、监测PetCO2(呼气末二氧化碳分压)、张口观察等，但在实际操作中各种间接检查手段虽发挥了重要作用，但因其间接方式本身存在固有局限性，存在误判的风险，因此，必要时需直接使用可视软镜检查。而直接使用可视软镜也存在一些问题。首先，可视软镜本身是重复使用器械，并且直接接触患者内部组织，所以需进行严格消毒，且严格消毒需要一定时间，消毒的操作流程相对较多，消毒成本相对会增加，并且对视像管本身的防浸泡性能要求也高，再者在消毒期间，医务人员不得不准备备用器械，客观上也增加了使用成本，即便如此也存在一定的交叉感染风险；其次，可视软镜成本相对较高，不属于可随意获取的备用器械，如在进行一些紧急气道处理时或在部分基层医疗机构里可能缺乏可视软镜；再次，可视软镜主要应用于喉罩插入后的检查或者引导气管插管通过喉罩进入声门，而不是在喉罩置入过程中实现全程可视，因此其难以有效减少喉罩的反复插入。In order to ensure the accuracy of the placement of the laryngeal mask, the operator often checks through various indirect means, such as observing chest rise and fall, lung compliance, auscultation for air leakage, observing neck bulge, and monitoring PetCO2 (end-tidal carbon dioxide However, although various indirect inspection methods have played an important role in actual operation, there is a risk of misjudgment due to the inherent limitations of the indirect method itself. Therefore, it is necessary to directly use visual Soft mirror inspection. There are also some problems in directly using the visual soft mirror. First of all, the flexible visual mirror itself is a reusable device and directly contacts the internal tissue of the patient, so strict disinfection is required, and strict disinfection takes a certain time. There are relatively many disinfection procedures, and the cost of disinfection will increase relatively. The anti-immersion performance requirements of the tube itself are also high. In addition, during the disinfection period, medical staff have to prepare spare equipment, which objectively increases the cost of use. Even so, there is a certain risk of cross-infection; It is relatively high, and it is not a spare device that can be obtained at will. For example, when performing some emergency airway treatment or in some primary medical institutions, there may be a lack of flexible visual mirrors; again, flexible visual mirrors are mainly used for inspection after laryngeal mask insertion Or guide the tracheal intubation through the laryngeal mask into the glottis instead of achieving full visibility during the laryngeal mask insertion process, so it is difficult to effectively reduce the repeated insertion of the laryngeal mask.
鉴于此，实现喉罩自身的可视功能显得很有必要，也出现了一系列的视频喉罩设计。In view of this, it is necessary to realize the visual function of the laryngeal mask itself, and a series of video laryngeal mask designs have emerged.
公开号为CN205814822U，名称为“可视插管喉罩”的发明专利中，图像传感器设置于喉罩气管内，线缆等沿喉罩气管内壁设置，图像传感器出口与气管远端出口平齐，线缆近端留有端口可连接显示屏及电源。此设计使得图像传感器只能预先固定地埋入喉罩内，使得图像传感器以及线缆等部件难以取出再用于其他喉罩，因此造成该喉罩的应用成本较高；并且，当病人会厌下垂时，会厌可能将图像传感器遮挡，导致无法获取完整的声门图像或完全无法获取声门图像。In the invention patent with the publication number CN205814822U and titled "Visual Intubation Laryngeal Mask", the image sensor is arranged in the trachea of the laryngeal mask, the cables are arranged along the inner wall of the trachea of the laryngeal mask, and the outlet of the image sensor is flush with the outlet of the distal end of the trachea. There is a port at the near end of the cable to connect the display screen and power supply. This design makes the image sensor only pre-fixedly embedded in the laryngeal mask, making it difficult to take out the image sensor and cables and other components for use in other laryngeal masks, so the application cost of the laryngeal mask is relatively high; , the epiglottis may obscure the image sensor, resulting in incomplete or complete glottal image acquisition.
发明内容Contents of the invention
针对上述问题，申请人通过无数次试验，设计出了一种视像管不与病人内部组织直接接触且视像管远端能够弯曲的喉罩(该设计未公开)，通过一种软管结构封闭视像管的远端，视像管的远端弯曲时带动软管结构跟随弯曲，通过视像管的远端的适度弯曲可以获得较好的视野，也可以绕开会厌或拨开会厌。但该设计方案对软管结构的结构强度和厚度提出了较为严苛的制造要求，既需要有较好的结构强度以满足质量可靠性，又需要厚度较薄，以具有良好的弯曲性能。In response to the above problems, the applicant has designed a laryngeal mask (the design is not disclosed) with a video tube that does not directly contact the patient's internal tissue and the distal end of the video tube can be bent through numerous experiments. The far end of the video tube is closed, and when the far end of the video tube bends, it drives the flexible tube structure to follow the bending. A better view can be obtained through the moderate bending of the far end of the video tube, and the epiglottis can also be bypassed or pushed aside.

It requires not only good structural strength to meet quality reliability, but also thinner thickness to have good bending performance.

Further, the video tube 22 The distal end can be bent and reset under the control of the control unit 23, so that the field of vision at the distal end of the video tube 22 can be adjusted according to actual needs.
本申请的实施例的喉罩主体3包括导管38、视像远端容纳组件30以及位于导管38远端的密封座37，当喉罩置入病人咽腔中后，密封座37用于封堵病人食道入口，以防止气体进入病人的胃部。可以理解的是，密封座37可以是一体式结构，例如使用硅酮成型的软体结构；密封座37也可以是气囊座37’和气囊37”的结构形式。本实施例中，密封座37包括气囊座37’和气囊37”。导管38内形成有通气通道以及用于容纳视像管22的视像腔道(图未标示)，视像管22可插拔地插入视像腔道内。视像腔道和通气通道均延伸至导管38的远端，通气通道的远端与密封座37内的空间连通。为了调整视像管22的远端的视野，请参阅图10和图11，视像管22的远端需要伸入至密封座37内部，以通过视像管22的远端的弯曲调整视野。The laryngeal mask main body 3 of the embodiment of the present application includes a conduit 38, a video distal end receiving component 30, and a sealing seat 37 located at the distal end of the conduit 38. When the laryngeal mask is placed in the patient's pharyngeal cavity, the sealing seat 37 is used to block the The patient's esophagus entrance to prevent gas from entering the patient's stomach. It can be understood that the sealing seat 37 can be an integrated structure, such as a soft structure formed by silicone; the sealing seat 37 can also be a structural form of an airbag seat 37' and an airbag 37". In this embodiment, the sealing seat 37 includes Airbag seat 37' and airbag 37".

Both the video cavity and the ventilation channel extend to the distal end of the conduit 38 , and the distal end of the ventilation channel communicates with the space in the sealing seat 37 . In order to adjust the field of view of the distal end of the video tube 22, please refer to FIG. 10 and FIG.
为了防止视像管22的远端与病人内部组织接触，请参阅图1-图4，视像远端容纳组件30包括第一软管31以及视窗件32，第一软管31用于容纳视像管22的远端，即第一软管31内形成有第一腔31a，视窗件32由透光材质制成，第一软管31的远端端部由视窗件32封闭。也就是说，第一腔31a的近端为开放结构，具体地，请参阅图8，第一软管31的近端与导管38的视像腔道连通，以使得视像管22能够插入第一腔31a内，第一腔31a的远端为盲端，如此能够避免视像管22与病人内部组织接触。视像管22采集病人内部组织的图像信号时，病人组织漫反射的光线需要透过视窗件32才能被视像管22的远端的图像传感器采集到。因此，视窗件32需要具有一定的透光性。In order to prevent the distal end of the video tube 22 from contacting the patient's internal tissue, please refer to Fig. 1-Fig. The distal end of the image tube 22 , that is, a first cavity 31 a is formed in the first hose 31 , and the window 32 is made of light-transmitting material, and the distal end of the first hose 31 is closed by the window 32 . That is to say, the proximal end of the first lumen 31a is an open structure. Specifically, please refer to FIG. In the first cavity 31a, the distal end of the first cavity 31a is a blind end, so as to avoid contact between the video tube 22 and the internal tissue of the patient. When the video tube 22 collects image signals of the patient's internal tissues, light diffusely reflected by the patient's tissue needs to pass through the window 32 to be collected by the image sensor at the far end of the video tube 22 . Therefore, the window member 32 needs to have a certain light transmittance.
当需要调整视像管22的远端的视野时，第一软管31需要跟随视像管22弯曲和复位，且由于喉罩属于置入病人口、咽腔内的人工气道，需要保证较高的质量可靠性，因此，第一软管31的厚度既需要保证结构强度，又需要具有良好的柔韧性。视像管22属于细长管体，其远端的弯曲的力度有限，如果第一软管31的厚度太厚，则会造成视像管22的弯曲和复位阻力增大，甚至可能无法弯曲；如果第一软管31像市场上的塑料薄膜一样，则主要存在以下两方面的安全问题：一、当视像管22的远端插入第一软管31内时，第一软管31被视像管22戳破的可能性较高；二、喉罩主体3置入病人体内后，病人自主呼吸或呼吸机运行时，喉罩通气通道会出现正负压交替的情况，第一软管31很有可能会发生飘动，可能会进入通气通道，封堵人工气道，进而可能出现病人供氧不够甚至窒息的风险。When it is necessary to adjust the field of vision at the far end of the video tube 22, the first flexible tube 31 needs to follow the video tube 22 to bend and reset, and since the laryngeal mask belongs to the artificial airway placed in the patient's mouth and pharyngeal cavity, it is necessary to ensure that the High quality reliability, therefore, the thickness of the first hose 31 needs to ensure structural strength and good flexibility. The video tube 22 belongs to a slender tube body, and the bending strength of its distal end is limited. If the thickness of the first flexible tube 31 is too thick, the bending and reset resistance of the video tube 22 will increase, and may even be impossible to bend; If the first flexible pipe 31 is the same as the plastic film on the market, then mainly there are safety problems in the following two aspects: one, when the far-end of video tube 22 is inserted in the first flexible pipe 31, the first flexible pipe 31 is viewed as The possibility of puncturing the image tube 22 is relatively high; 2. After the main body of the laryngeal mask 3 is placed in the patient's body, when the patient breathes spontaneously or the ventilator is running, the ventilation channel of the laryngeal mask will alternate positive and negative pressures, and the first hose 31 It is very likely to flutter, enter the ventilation channel, and block the artificial airway, which may lead to the risk of insufficient oxygen supply or even suffocation of the patient.
请参阅图4，第一软管31包括第一波纹段310以及沿第一波纹段310的长度方向沿伸的第一筋条311，第一波纹段310的内壁为平滑结构，第一波纹段310存在波峰和波谷，由于第一波纹段310的内壁是平滑结构，因此，波峰处的厚度会大于波谷处的厚度，沿第一波纹段310的长度方向，波峰和波谷交替排列，使得第一波纹段310的厚度在长度方向上呈现厚、薄交替排列。Referring to Fig. 4, the first hose 31 includes a first corrugated section 310 and a first rib 311 extending along the length direction of the first corrugated section 310, the inner wall of the first corrugated section 310 is a smooth structure, and the first corrugated section There are crests and troughs at 310. Since the inner wall of the first corrugated section 310 is a smooth structure, the thickness at the crests will be greater than the thickness at the troughs. Along the length direction of the first corrugated section 310, the crests and troughs are arranged alternately, so that the first The thickness of the corrugated section 310 is alternately arranged thick and thin in the length direction.
可以理解的是，在软管的成型过程中，当软管的厚度越薄，用于浇注软管的原浆料在模具中的流动性会越差，原浆料可能无法充分地流动至流动方向的末端处，进而导致软管的原浆料的流动末端处的结构可能存在漏洞，软管为废品；或者厚薄不均，薄的地方极薄，导致软管极易破损，质量不合格。为此，本申请中，第一筋条311的厚度大于第一波纹段310的波谷处对应的厚度。在第一软管31注塑成型过程中，原浆料沿模具的与第一筋条311对应位置的方向流动，第一筋条311类似流动主干道，由于第一筋条311的厚度较厚，也就是说，模具的对应于第一筋条311的位置的空间较大，能够降低原浆料的流动阻力，原浆料能够顺畅地流动；原浆料从第一筋条311对应的位置向其横向两侧的波峰处对应的位置流动，波峰处类似于流动支流，由于波峰处的厚度较厚，因此，也能降低原浆料的流动阻力，使得原浆料能够填满模具的与波峰处对应的位置；同时，进入模具的波峰处的原浆料可以从波峰处向波峰两侧流动，波谷处的厚度较薄，原浆料在模具内的流动阻力较大，但相邻两波峰处的对应位置的原浆料可同时向中间的波谷处对应的位置流动，原浆料流动的距离较短，原浆料能够满足充分地到达波谷处对应的位置进行成型。It is understandable that in the molding process of the hose, when the thickness of the hose is thinner, the fluidity of the raw slurry used for casting the hose will be poorer in the mold, and the raw slurry may not be able to flow sufficiently to flow At the end of the direction, there may be loopholes in the structure at the end of the flow of the original slurry of the hose, and the hose is a waste product; or the thickness is uneven, and the thin place is extremely thin, causing the hose to be easily damaged and the quality is unqualified. For this reason, in the present application, the thickness of the first rib 311 is greater than the corresponding thickness at the trough of the first corrugated section 310 . During the injection molding process of the first hose 31, the original slurry flows along the direction of the position corresponding to the first rib 311 of the mold. The first rib 311 is similar to the main flow channel. Since the thickness of the first rib 311 is relatively thick, That is to say, the space corresponding to the position of the first rib 311 of the mold is relatively large, which can reduce the flow resistance of the original slurry, and the original slurry can flow smoothly; the original slurry flows from the position corresponding to the first rib 311 to It flows at the corresponding position of the wave crests on both lateral sides, and the wave crests are similar to the flow tributaries. Because the thickness of the wave crests is thicker, it can also reduce the flow resistance of the original slurry, so that the original slurry can fill the mold and the wave crests. at the corresponding position; at the same time, the original slurry entering the wave crest of the mold can flow from the wave peak to both sides of the wave peak, the thickness of the wave trough is thinner, and the flow resistance of the original slurry in the mold is larger, but the two adjacent wave peaks The original slurry at the corresponding position at the center can flow to the corresponding position at the middle trough at the same time, the distance of the original slurry flowing is short, and the original slurry can fully reach the corresponding position at the trough for molding.
通过第一筋条311和波峰的设计，能使得波谷具有较薄的厚度以及较高的质量可靠性。由于波谷的厚度相对较薄，能够使得第一软管31具有很好的柔韧性，能够跟随视像管22同步弯曲和复位。第一筋条311和波峰的厚度设计同时也增加了第一软管31的结构强度，使得第一软管31不会在正负压交替的作用下变形进而堵塞通气通道。Through the design of the first rib 311 and the crest, the trough can have a thinner thickness and higher quality reliability. Because the thickness of the trough is relatively thin, the first flexible tube 31 can be made to have good flexibility, and can be bent and reset synchronously with the video tube 22 . The thickness design of the first rib 311 and the wave crest also increases the structural strength of the first hose 31 , so that the first hose 31 will not be deformed under the action of positive and negative pressure alternately to block the ventilation channel.
可以理解的是，第一波纹段310位于第一软管31的弯曲处(参照图11)，如此才能发挥第一波纹段310的便于弯曲的效果。It can be understood that the first corrugated section 310 is located at the bend of the first hose 31 (refer to FIG. 11 ), so that the first corrugated section 310 can be easily bent.
本申请实施例中，视像管22的远端一般是朝向病人的声门方向弯曲，也就是说，大致是向背离密封座37的底部的方向弯曲。第一软管31的弯曲方向与视像管22的远端的弯曲方向相同。可以理解的是，第一软管31弯曲时存在材料学意义上的中性层，中性层指的是：材料在弯曲过程中，弯曲外层受拉伸，弯曲内层受挤压，在其断面上必然会有一个既不受拉，又不受压的过渡层，应力几乎等于零，这个过渡层称为材料的中性层，中性层在弯曲过程中的长度和弯曲前一样，保持不变。In the embodiment of the present application, the distal end of the video tube 22 is generally bent toward the patient's glottis, that is to say, is generally bent away from the bottom of the sealing seat 37 . The bending direction of the first hose 31 is the same as that of the distal end of the video tube 22 . It can be understood that when the first hose 31 is bent, there is a neutral layer in the sense of material science. The neutral layer refers to: during the bending process of the material, the outer layer of the bend is stretched, and the inner layer of the bend is squeezed. There must be a transition layer on its section that is neither tensile nor compressive, and the stress is almost equal to zero. This transition layer is called the neutral layer of the material. The length of the neutral layer during bending is the same as that before bending, keeping constant.
本申请实施例中的第一筋条311设置于第一软管31的中性层所在面内。如此，当第一软管31弯曲时，第一筋条311基本不会对第一软管31的弯曲产生弯曲阻力。第一软管31的外表面中，中性层所在面与第一软管31的外表面的相交处存在两个位置，两个位置关于第一软管31的轴线对称分布，因此，在该两个位置处可以各设置一个第一筋条311，也可以只设置一个第一筋条311。The first rib 311 in the embodiment of the present application is arranged in the plane where the neutral layer of the first hose 31 is located. In this way, when the first hose 31 is bent, the first rib 311 basically does not produce bending resistance to the bending of the first hose 31 . In the outer surface of the first hose 31, there are two positions at the intersection of the surface where the neutral layer is located and the outer surface of the first hose 31, and the two positions are distributed symmetrically with respect to the axis of the first hose 31. Therefore, in this One first rib 311 may be provided at each of the two positions, or only one first rib 311 may be provided.
进一步，第一筋条311的厚度大于或等于第一波纹段310的波峰处对应的厚度。如此，能够保证原浆料能够从模具的第一筋条311处对应的位置顺畅地流动至波峰处对应的位置。本申请具体实施例中，第一筋条311的厚度与第一波纹段310的波峰处的厚度相等，以减少模具制造难度，降低对模具的精度要求。Further, the thickness of the first rib 311 is greater than or equal to the corresponding thickness at the crest of the first corrugated section 310 . In this way, it can be ensured that the raw slurry can flow smoothly from the position corresponding to the first rib 311 of the mold to the position corresponding to the wave crest. In a specific embodiment of the present application, the thickness of the first rib 311 is equal to the thickness of the crest of the first corrugated section 310, so as to reduce the difficulty of mold manufacturing and lower the precision requirements for the mold.

Cylindrical, the first sleeve portion 321 extends from the edge of the cover 320 toward the direction of the first hose 31 , that is, extends toward the inner side of the cover 320 , please refer to FIG. 4 , the distal end of the first hose 31 The first sleeve portion 321 is sleeved on the outer surface of the first hose 31 , for example, by bonding. The second socket part 322 is located on the side of the cover body 32 close to the second hose 33, the second socket part 322 is connected to the outer surface of the first socket part 321, and the second socket part 322 is socketed on the second The outer surface of the hose 33 is, for example, bonded to the outer surface of the fourth connecting section 333 .
本申请实施例的视窗件32，通过第二套接部322套接于第二软管33的外表面，增加了视窗件32的粘接面积，提升了视窗件32的连接可靠性，防止视窗件32脱落。为了便于打胶，第二套接部322的远端端部为开放结构，第二软管33的远端端部凸出于第二套接部322的远端端部，如此，可从第二套接部322的远端方向打胶，使得粘胶填充在第二软管33和第二套接部322的交界处。The window piece 32 of the embodiment of the present application is socketed on the outer surface of the second hose 33 through the second sleeve part 322, which increases the bonding area of the window piece 32, improves the connection reliability of the window piece 32, and prevents the window Part 32 falls off. In order to facilitate glue application, the distal end portion of the second sleeve portion 322 is an open structure, and the distal end portion of the second hose 33 protrudes from the distal end portion of the second sleeve portion 322. The distal direction of the two socket parts 322 is glued, so that the glue is filled at the junction of the second hose 33 and the second socket part 322 .
进一步，请参阅图4，盖体320的外侧表面凸出于第二套接部322的远端端部，沿第二软管33的长度方向，第二软管33的远端端部与盖体320的外侧表面之间的间隔距离小于预定长度，以降低导光件39对视像管22的远端的成像干扰。所述的预定长度的具体数值满足：导光件39的远端端部的发光基本不会对视像管22的远端的成像产生干扰。Further, referring to FIG. 4 , the outer surface of the cover body 320 protrudes from the distal end of the second sleeve portion 322 , along the length direction of the second hose 33 , the distal end of the second hose 33 is in contact with the cover. The distance between the outer surfaces of the body 320 is less than a predetermined length, so as to reduce the image interference of the light guide 39 on the distal end of the video tube 22 . The specific numerical value of the predetermined length satisfies that: the light at the distal end of the light guide member 39 basically does not interfere with the imaging at the distal end of the video tube 22 .
