Description

[根据细则37.2由ISA制定的发明名称]　具有可弃性喉镜片的通气喉镜 技术领域：
本发明涉及一种喉镜，尤其是涉及一种可弃性喉镜片的通气喉镜。
背景技术：
麻醉咽喉镜是全麻诱导和心肺复苏用于气管插管显露声门首选的医疗器械。麻醉咽喉镜的喉镜片大多是重复使用，而目前逐步被一次性可弃喉镜片的麻醉咽喉镜所替代，其目的是因为消毒不彻底防止重复使用给患者造成交叉感染，但现有的一次性可弃喉镜片的麻醉咽喉镜其存在的缺点是：功能单一，无法应对困难气道插管的患者，当遇到高喉头、颈短、上牙前凸、肥胖等疑难困难插管的患者时不能进行通气供氧，易造成脑心肾重要脏器缺氧加重。学术界对呼吸衰竭或呼吸骤停患者插管的完成时间有明确的界定时限(15-20秒)，这样的界定时限对于一位训练有素资深的麻醉医师遇到困难气道时，也很难在界定的安全时限内顺利完成，从而危及抢救复苏的成败。
同时现有的一次性可弃喉镜片的麻醉咽喉镜不具有雾化麻醉的功能，它只能检察观察显露声门，在遇到喉痉挛声门紧闭时，不能向声门雾化麻醉，无法使声门松弛和减轻插管的应激反应，处理不好使窒息加重而危及生命；完全不能满足上述明确的界定时限，达不到抢救的目的，往往造成抢救失败。同时在现场心肺复苏过程中遇到静脉穿刺困难无法通过静脉给药的紧急时刻，其现有的一次性可弃喉镜片不具备通过气道向体内雾入心肺复苏药物的功能，如付肾素、阿托品 等急救药物。因此，无法达到通过气道给药抢救危重患者的目的。(气道给药和静脉给药的吸收速率是一致的)。
当遇到患者口内有出血液、呕吐等分泌物遮盖摄像头透明护盖时，现有的一次性可弃喉镜片无法采集到视频图像或无法清晰观察声门，影响插管的顺利完成，贻误抢救。

本发明的优点是：(1)在气管插管过程中可以向体内进行通气供氧，迅速提高氧分压，为防止脑缺氧提高心肺复苏的成功率，提供了安全可靠的保障。(2)对于高喉头、颈短、上牙前凸、舌根后移、肥胖等疑难插管的患者，可实施通气供氧插管，能有效地延长气管插管的安全时限，提高插管的安全性，降低插管的职业风险。(3)在使用直型一种可弃性喉镜片的通气喉镜在抢救新生儿紧急窒息时更显其优势，新生儿的插管难度比成人插管困难度更大，由于新生儿的生理解剖特点，头大、肩薄、会厌呈U型，喉头位置较高，位于3-4颈椎平面，气道呈漏斗状，上述解剖特点增加了新生儿的插管难度。据世界卫生组织统计，每年400多万新生儿死亡中的约1/4死于新生儿窒息，还有100万以上婴儿在分娩窒息后出现脑瘫、学习障碍和其它残疾。新生儿也是我国5岁以下儿童的第二位死因。新生儿插管的安全时限与成人是一致的(15-20秒)，这样更增加了新生儿的复苏难度和紧迫感。可弃性喉镜片的通气喉镜可以在新生儿窒息插管的第一时间向体内通气供氧，将无氧插管变为有通气供氧插管，可延长气管插管的安全时限，为防止新生儿脑缺氧奠定了坚实的保障，可有效地降低新生儿的死亡率和脑瘫、智障儿、残疾儿的发病率。
(4)在气管插管的过程中，当遇到患者口内有出血液、呕吐等分泌物遮盖摄像头透明护盖无法采集到视频图像或无法清晰观察声门时，具有除污功能的可弃性喉镜片的通气喉镜，可及时清除摄像头 透明护盖上的分泌物，可清晰地采集到声门图像，便于顺利完成插管，达到及时抢救危重患者的目的。
(5)本发明还具备有通过气道喷入心肺复苏药物和向声门麻醉的功能。在现场心肺复苏抢救危重患者，在遇到静脉穿刺困难无法通过静脉给药时，本发明的喉镜可立刻通过气道将心肺药物如阿托品、肾上腺素等急救物喷入体内，可达到快速给药分秒必争的抢救危重患者的目的；(气道给药和静脉给药的吸收速率是一致的)同时还可针对喉痉挛声门紧闭危及生命的垂危患者可立刻向其声门雾化麻醉，使声门松弛，减轻气管插管的应激反应，便于顺利完成插管，达到及时有效地抢救垂危患者。
