本发明涉及医疗器械领域，尤其涉及用于无痛内镜时使用的面罩装置。The invention relates to the field of medical instruments, in particular to a mask device used for painless endoscopy.
背景技术Background technique
呼吸面罩是在手术麻醉或抢救呼吸骤停的患者时，为患者提供氧气的一种辅助呼吸装置，该呼吸装置通过与呼吸机或者呼吸囊的连通，给患者供氧，这一操作通常由麻醉医师来完成。传统呼吸面罩的气道只有一种连接方式，即气道的一端与面罩相连，另一端与呼吸机或呼吸囊相连。因此在使用无痛内窥镜设备时候，比如胃镜或纤支镜时，就必须将面罩摘掉，如此不能达到不间断供氧的目的，影响手术进行，甚至延误宝贵的抢救时间。The breathing mask is an auxiliary breathing device that provides oxygen to the patient during surgical anesthesia or rescue of a patient in respiratory arrest. The breathing device supplies oxygen to the patient through communication with a ventilator or a breathing bag. Physician to complete. The airway of a traditional breathing mask has only one connection mode, that is, one end of the airway is connected with the mask, and the other end is connected with the ventilator or breathing bag. Therefore, when using painless endoscopic equipment, such as gastroscope or bronchoscope, the mask must be taken off, which cannot achieve the purpose of uninterrupted oxygen supply, affects the operation, and even delays the precious rescue time.
为此，公告号为CN203107902U的中国实用新型提出了一种多功能给氧面罩，以解决麻醉医师和内窥镜科医师共用气道的问题，但是为防止面罩医疗检查导管插入口漏气的结构部件过于复杂，需要进一步改进。For this reason, the Chinese utility model whose notification number is CN203107902U has proposed a kind of multifunctional oxygen supply mask, to solve the problem that the anesthetist and the endoscopist share the airway, but in order to prevent the structure of the mask medical inspection catheter insertion port from leaking Parts are too complex and need further improvement.

具体实施方式Detailed ways
下面将结合实施例中的附图，对本实用新型实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本实用新型一部分实施例，而不是全部的实施例。基于本实用新型中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本实用新型保护的范围。The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.
参考图1所示，本实用新型的特定实施例公开了一个用于全麻医疗内窥镜面罩装置100，其包括罩体10和与该罩体10连通的三通道连接头20。该三通道连接头20包括医疗通道1和进气通道2。在检查或治疗时，医疗通道1的入口端部11上设置入口12，以供内窥镜管3(例如支气管镜或胃镜等)穿过该入口12而延伸进入医疗通道1，以进行检查或治疗。进气通道2与外界供氧设备(例如呼吸囊或呼吸机等)连通。如此可以解决麻醉医师和手术医师共用气道的难题。如果在检查或治疗时发生呼吸抑制缺氧，可以直接加压给氧，而无需撤出内窥镜，不影响检查或治疗，使得检查或治疗能够安全、无痛、顺利的完成。Referring to FIG. 1 , a specific embodiment of the present invention discloses a medical endoscopic mask device 100 for general anesthesia, which includes a mask body 10 and a three-channel connector 20 communicating with the mask body 10 . The three-channel connector 20 includes a medical channel 1 and an air intake channel 2 . During inspection or treatment, an inlet 12 is provided on the inlet end 11 of the medical channel 1, so that the endoscope tube 3 (such as a bronchoscope or gastroscope, etc.) passes through the inlet 12 and extends into the medical channel 1 for inspection or treatment. treat. The air intake channel 2 communicates with external oxygen supply equipment (such as a breathing bag or ventilator, etc.). This can solve the problem that anesthesiologists and surgeons share the airway. If respiratory depression and hypoxia occur during examination or treatment, oxygen can be directly pressurized without withdrawing the endoscope, which will not affect the examination or treatment, so that the examination or treatment can be completed safely, painlessly and smoothly.
结合参考图2和图3所示，为了解决医疗通道1的气密性问题，在医疗通道入口12的内口沿与内窥镜管3的外表面之间设置密封件4，以保证在检查或治疗过程中呼吸道的密封性。2 and 3, in order to solve the airtightness of the medical channel 1, a seal 4 is provided between the inner edge of the medical channel inlet 12 and the outer surface of the endoscope tube 3 to ensure Or the tightness of the airway during treatment.
结合参考图3、4和5，密封件4包括中空的管部41和管帽部42。管部41 可穿过医疗通道入口12，管帽部42可抵靠于入口12的周边以阻止管部41进一步延伸穿过入口12的趋势，防止整个密封件4完全被塞进医疗通道1。内窥镜管3可穿过中空的管部41以使得整个密封件4套设于内窥镜管3上。密封件4被设置为可移动地套设于内窥镜管3上。如此可以轻易调整密封件4在内窥镜管3上的位置，使得内窥镜管3可以被轻易地调整延伸进入医疗通道1内部的长度，甚至可以调整内窥镜管3的方向。Referring to FIGS. 3 , 4 and 5 in combination, the sealing member 4 includes a hollow tube portion 41 and a tube cap portion 42 . The tube part 41 can pass through the medical channel inlet 12 , and the tube cap part 42 can abut against the periphery of the inlet 12 to prevent the tube part 41 from extending further through the inlet 12 and prevent the entire sealing member 4 from being completely inserted into the medical channel 1 . The endoscope tube 3 can pass through the hollow tube portion 41 so that the entire sealing member 4 is sleeved on the endoscope tube 3 . The sealing member 4 is arranged to be movably sleeved on the endoscope tube 3 . In this way, the position of the sealing member 4 on the endoscope tube 3 can be easily adjusted, so that the length of the endoscope tube 3 extending into the medical channel 1 can be easily adjusted, and even the direction of the endoscope tube 3 can be adjusted.
当密封件4被塞入入口12后，由于各个部件的相互挤压，管部41的内壁面可以与内窥镜管3的外表面紧密贴合，管部41的外壁面可以与入口12的内口沿紧密贴合，如此更进一步地提高医疗通道1的气密性。因此密封件4被设置为一种橡胶件则是一种更好选择，橡胶件本身弹性柔软特性有利于更好保证气密性。After the sealing member 4 is inserted into the inlet 12, due to the mutual extrusion of each component, the inner wall surface of the tube portion 41 can be closely attached to the outer surface of the endoscope tube 3, and the outer wall surface of the tube portion 41 can be in contact with the outer surface of the inlet 12. The edge of the inner mouth is closely fitted, so that the airtightness of the medical channel 1 is further improved. Therefore, it is a better choice that the sealing member 4 is set as a rubber member, and the rubber member itself is elastic and soft, which is beneficial to better ensure the airtightness.
如图6所示，本实施例内窥镜面罩装置还包括盖子5，可以盖住医疗通道 1的入口端部11，从而完全封闭入口12，保证医疗通道1的气密性。如此当不通过医疗通道1使用内窥镜时，医疗通道1的入口12可以被封闭而不会漏气。整个面罩装置仅仅当作供氧面罩在使用。As shown in Figure 6, the endoscopic mask device of the present embodiment also includes a cover 5, which can cover the inlet end 11 of the medical channel 1, thereby completely sealing the inlet 12 and ensuring the airtightness of the medical channel 1. In this way, when the endoscope is not used through the medical channel 1, the inlet 12 of the medical channel 1 can be sealed without air leakage. The entire mask assembly is only used as an oxygen mask.
