本申请涉及医疗器械技术领域，尤其涉及一种喉罩及视频喉罩。The present application relates to the technical field of medical devices, and in particular to a laryngeal mask and a video 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 respiratory tract. Since its invention in 1983, it has been widely used in clinical practice due to its advantages such as easy operation, high success rate, and minimal damage. The laryngeal mask is an artificial airway device between a mask and an endotracheal tube. It allows patients to maintain spontaneous breathing and implement positive pressure ventilation.
无可视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、经验插入。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。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在患者体内的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。Laryngeal masks without visual function are usually blindly inserted into the patient's body. Since the details of the throat cannot be seen during operation, the operator can only insert based on feel and experience. Blind insertion is likely to lead to inaccurate placement of the laryngeal mask. Inaccurate positioning may lead to a series of subsequent problems, such as inability to effectively isolate the respiratory tract and digestive tract, resulting in incomplete laryngeal mask sealing, air leakage, and patient gastric bloating and reflux. , or even aspiration. When one or more of the above problems occur, the operator has to readjust the angle of the laryngeal mask in the patient's body or repeatedly insert it multiple times, which may prolong the operation time and delay the rescue of critically ill patients. Moreover, repeated insertion attempts may cause an increase in oral mucus in the patient's mouth, making the operation more difficult.
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，如浸泡消毒，严格消毒所需时间相对较长，程序较多，且消毒期间医务人员不得不使用备用器械，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 laryngeal mask placement, operators often check through various indirect methods, such as observing chest rise and fall, lung compliance, auscultation for air leakage, observing neck bulge, and monitoring PetCO2 (end-tidal carbon dioxide). partial pressure), mouth opening observation, etc. However, although various indirect inspection methods play an important role in actual operations, the indirect method itself has inherent limitations and risks of misjudgment. Therefore, direct visual inspection is required when necessary. Soft microscopy. There are also some problems in directly using the visual soft lens. First of all, the flexible visual lens itself is a reusable device and directly contacts the patient's internal tissue, so it needs to be strictly disinfected, such as immersion disinfection. Strict disinfection requires a relatively long time and many procedures, and medical staff have to use it during disinfection. Spare equipment objectively increases the cost of use. Even so, there is a certain risk of cross-infection. Secondly, the cost of flexible visual lenses is relatively high and is not a spare equipment that can be obtained at will, such as when performing some emergency airway treatments or There may be a lack of flexible videoscopes in some primary medical institutions; thirdly, flexible videoscopes are mainly used for inspection after laryngeal mask insertion or to guide the tracheal intubation through the laryngeal mask and into the glottis, rather than during the laryngeal mask insertion process. The entire process is visible, so it is difficult to effectively reduce 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.
但是随着喉罩的功能逐渐增多，喉罩中的腔道数量也随之增加，从而导致喉罩导管及连接座的尺寸越来越大，而患者的张口度及上呼吸道空间有限，更有甚者部分病人的张口度原本就小或者口、咽腔狭窄，以上尺寸的加大可能严重影响患者的舒适性，或者导致喉罩难以准确插入患者体内。However, as the function of the laryngeal mask gradually increases, the number of lumens in the laryngeal mask also increases, resulting in the size of the laryngeal mask tube and connecting seat becoming larger and larger. The patient's mouth opening and upper respiratory tract space are limited, and more What's more, the mouth opening of some patients is originally small or the oral and pharyngeal cavities are narrow. The increase in the above size may seriously affect the patient's comfort, or make it difficult to accurately insert the laryngeal mask into the patient's body.

为了使得气流能够高效地引入患者的肺部，请参阅图5至图8，本申请实施例中，喉罩包括填充件60，填充件60设置在插接柱22中，使得喉罩在不增加尺寸的情况下，能够有效地固定了导光件和胃管。In order to enable the airflow to be efficiently introduced into the patient's lungs, please refer to Figures 5 to 8. In the embodiment of the present application, the laryngeal mask includes a filler 60, and the filler 60 is disposed in the insertion post 22, so that the laryngeal mask does not increase in size. The light guide and the gastric tube can be effectively fixed despite the small size.
具体地，填充件60设置在装配通道22b的侧壁与导光件40、胃管50和视像腔道12a的侧壁之间的间隙中。Specifically, the filling piece 60 is disposed in the gap between the side walls of the assembly channel 22b and the side walls of the light guide 40, the gastric tube 50 and the imaging tract 12a.
由于导光件40、胃管50和视像腔道12a均穿设于装配通道22b以及导气通道10a中，导气通道10a连通呼吸通道20a和密封座30内的空间，也就是说，装配通道22b内不可避免的存在死腔，死腔指的是影响通气效率的无效腔体，较大容量的死腔可能会影响患者气道的有效气流的交换，尤其是对于儿童用的喉罩，通气量本来就比较少，较大容量的死腔的存在对患者会产生较大的安全隐患。因而，通过在装配通道22b的侧壁与导光件40、胃管50和视像腔道12a的侧壁之间的间隙中设置填充件60，通过填充件60填充装配通道22b内的死腔，由此，提高了气流流动效率，使得气流能够高效地引入患者的肺部。Since the light guide 40, the gastric tube 50 and the video cavity 12a are all penetrated in the assembly channel 22b and the air guide channel 10a, the air guide channel 10a connects the breathing channel 20a and the space in the sealing seat 30, that is to say, the assembly There is inevitably a dead space in the channel 22b. The dead space refers to the ineffective cavity that affects the ventilation efficiency. A large dead space may affect the exchange of effective airflow in the patient's airway, especially for children's laryngeal masks. The ventilation volume is inherently small, and the presence of a larger volume of dead space will pose greater safety risks to the patient. Therefore, by disposing the filling piece 60 in the gap between the side walls of the assembly channel 22b and the light guide 40, the gastric tube 50 and the side walls of the imaging tract 12a, the dead space in the assembly channel 22b is filled by the filling piece 60 , thereby improving the air flow efficiency, allowing the air flow to be efficiently introduced into the patient's lungs.
同时，通过设置填充件60，便于导光件40和胃管50的装配固定，使得气流流经导气通道10a时，导光件40和胃管50不会出现明显晃动和产生异响；此外，填充件60的设置降低了连接座20的开模制造难度，生产过程中，填充件装配简单，易操作。At the same time, the filling member 60 is provided to facilitate the assembly and fixation of the light guide member 40 and the stomach tube 50, so that when the airflow flows through the air guide channel 10a, the light guide member 40 and the stomach tube 50 will not cause obvious shaking or abnormal noise; in addition, , the setting of the filling piece 60 reduces the difficulty of mold opening and manufacturing of the connecting seat 20. During the production process, the filling piece is simple to assemble and easy to operate.

The respiratory tract 22a and the assembly channel 22b are arranged along the width direction of the catheter 10, and the gastric tube 50 and the tube body 12 are arranged along the thickness direction in the assembly channel 22b. That is to say, the respiratory tract 22a is located on one side of the insertion column 22 in the width direction, and the light guide 40, the gastric tube 50 and the tube body 12 are located on the other side of the insertion column 22 in the width direction, so that the light guide 40, the gastric tube 50 and the tube body 12 The arrangement does not interfere with the arrangement of the respiratory cavity 22a, and through reasonable layout, the overall size of the laryngeal mask can be made as small as possible without affecting the use.

由于胃管50和管体12的横截面形状均大致呈圆形，因而胃管50和管体12的中心连线的相对两侧与装配通道22b的侧壁之间均存在死腔，由此，通过在胃管50和管体12的中心连线的相对两侧的空间均设置有填充件60，用于填充胃管50和管体12的中心连线的相对两侧的死腔，提高通气效率，使得气流能够高效地引入患者的肺部。Since the cross-sectional shapes of the gastric tube 50 and the tube body 12 are both substantially circular, there is a dead space between the opposite sides of the central line connecting the gastric tube 50 and the tube body 12 and the side walls of the assembly channel 22b. Therefore, , by disposing filling pieces 60 in the spaces on opposite sides of the central connection between the gastric tube 50 and the tube body 12, for filling the dead spaces on opposite sides of the central connection between the gastric tube 50 and the tube body 12, improving the Ventilation efficiency allows airflow to be efficiently introduced into the patient's lungs.
请参阅图5，其中两个填充件60将胃管50约束在两者之间，能够减少胃管50周侧形成的死腔，胃管50的近端虽然通过密封地穿过胃管连接口23b固定在连接座20上，但是，为了防止气流流经导气通道10a时，胃管50不会出现明显晃动和产生异响，通过两个填充件60将胃管50约束在两者之间，一方面能够对胃管50进行限位，防止胃管50在插接柱22内出现明显晃动，另一方面，能够保证胃管50装配到位，不干涉安装区域内其他零部件的装配，且防止了胃管50由于在插接柱22内晃动而导致的与连接座20的密封性连接出现问题。Please refer to Figure 5, in which two filling pieces 60 constrain the gastric tube 50 between them, which can reduce the dead space formed around the gastric tube 50. Although the proximal end of the gastric tube 50 passes through the gastric tube connection opening in a sealing manner, 23b is fixed on the connecting seat 20. However, in order to prevent the gastric tube 50 from significantly shaking and making abnormal noise when the airflow flows through the air guide channel 10a, the gastric tube 50 is restrained between the two filling pieces 60. , on the one hand, the gastric tube 50 can be limited to prevent the gastric tube 50 from obvious shaking in the insertion post 22; on the other hand, it can ensure that the gastric tube 50 is assembled in place without interfering with the assembly of other parts in the installation area, and This prevents problems in the sealing connection between the gastric tube 50 and the connecting seat 20 due to rocking in the insertion post 22 .

一实施例中，请参阅图8，填充件60设置有卡槽60a，卡槽60a将导光件40约束在其内。In one embodiment, please refer to FIG. 8 , the filling member 60 is provided with a slot 60 a, and the slot 60 a constrains the light guide 40 therein.
卡槽60a将导光件40约束在其内，能够减少导光件40周侧形成的死腔，导光件40的近端虽然通过密封地穿过导光口23a固定在连接座20上，但是，为了防止气流流经导气通道10a时，导光件40不会出现明显晃动和产生异响，通过卡槽60a将导光件40约束在其内，一方面能够对导光件40进行限位，防止导光件40在插接柱22内出现明显晃动，另一方面，能够保证导光件40装配到位，不干涉安装区域内其他零部件的装配。The card slot 60a constrains the light guide 40 therein, which can reduce the dead space formed around the light guide 40. Although the proximal end of the light guide 40 is fixed to the connection base 20 by sealingly passing through the light guide opening 23a, However, in order to prevent the light guide 40 from significantly shaking and making abnormal noise when the airflow passes through the air guide channel 10a, the light guide 40 is restrained in the slot 60a. On the one hand, the light guide 40 can be The position limiting prevents the light guide 40 from shaking significantly in the plug-in post 22. On the other hand, it ensures that the light guide 40 is assembled in place without interfering with the assembly of other components in the installation area.
在一些实施方式中，也可以是其中两个填充件60将导光件40约束在两者之间。In some embodiments, it is also possible that two fillers 60 constrain the light guide 40 therebetween.
一实施例中，请参阅图9，导管10的内壁设置有定位环13，胃管50穿设于定位环13内，以对处于导气通道10a中的导管10部分进行定位，以保证胃管50能够装配到位，在不干涉导光件40装配到导气通道10a中的同时，尽可能减小对气流在导气通道10a中的流动的影响，此外，还可以防止气流流经导气通道10a时，胃管50出现明显晃动和产生异响。In one embodiment, please refer to Figure 9. The inner wall of the catheter 10 is provided with a positioning ring 13, and the gastric tube 50 is inserted into the positioning ring 13 to position the portion of the catheter 10 in the air conduction channel 10a to ensure that the gastric tube is 50 can be assembled in place, without interfering with the assembly of the light guide 40 into the air guide channel 10a, and at the same time minimizing the impact on the flow of air flow in the air guide channel 10a. In addition, it can also prevent the air flow from flowing through the air guide channel. At 10a, the gastric tube 50 was obviously shaking and making abnormal noises.
考虑到患者张口度和舒适性，需要尽可能的减小导管10和密封座30的外形尺寸，以提高患者的舒适性以及喉罩的可置入性，因而为了胃管50和导光件40在导气通道10a中的合理布局，胃管50和管体12由在装配通道22b中沿导管10的厚度方向布置，逐渐变为在导管10中沿导管10的宽度方向布置，充分利用了导气通道10a的空间，由此，有效的减小了导管10的外形尺寸。Considering the patient's mouth opening and comfort, it is necessary to reduce the outer dimensions of the catheter 10 and the sealing seat 30 as much as possible to improve the patient's comfort and the insertability of the laryngeal mask. Therefore, for the gastric tube 50 and the light guide 40 In the reasonable layout in the air guide channel 10a, the gastric tube 50 and the tube body 12 are gradually arranged from being arranged along the thickness direction of the catheter 10 in the assembly channel 22b to being arranged along the width direction of the catheter 10, making full use of the guide tube 10. The space of the air passage 10a thus effectively reduces the overall size of the conduit 10.
具体地，定位环13设置在导管10的外形尺寸变小处，即设置在胃管50沿长度方向的拐弯处，胃管50穿设于定位环13后，与管体12沿导管10的宽度方向布置。Specifically, the positioning ring 13 is disposed at a place where the outer size of the catheter 10 becomes smaller, that is, at a corner of the gastric tube 50 along the length direction. The gastric tube 50 is inserted behind the positioning ring 13 and is aligned with the tube body 12 along the width of the catheter 10 Orientation arrangement.
