Description
本实用新型涉及一种喉罩,尤其是一种高适应性喉罩,属于喉罩的技术领域。
喉罩作为一种用于维护患者呼吸换气的医疗器械,因其非侵入气道的特点在临床麻醉、急救或复苏中得到广泛应用。随着材料和技术的进步,已有多种改进型的喉罩应用于临床。
由于不同患者的咽喉腔不同,在利用喉罩进行呼吸换气时,常会出现喉罩与患者喉咽腔无法有效匹配的情况,导致喉罩与咽喉腔无法有效配合,从而影响呼吸支持的效果,甚至导致的呼吸支持的失败。
对于现有采用气囊包绕声门实施密封效果的喉罩,可通过调节气囊的充气状态尽可能地去适配不同患者的咽喉腔。但对于采用气囊包绕声门实施密封效果的喉罩,其密封本质为气囊对环绕声门的咽喉粘膜按压,其压力与气体泄漏的压力垂直,密封效果较差,达到临床密封效果需要较大的压力,常导致患者术后咽喉疼痛;而压力较低时,又常发生气体泄漏,导致通气失败或口水流进气道发生误吸。

在所述罩主体2的侧壁设置具有弹性形变能力的往返折叠弹性体,在所述罩主体2的内圈上缘设置密封膜5;罩主体2通过往返折叠弹性体产生弹性形变后,能使得罩主体2与待置入的咽喉腔快速匹配,以便于将罩体置入咽喉腔内,且在置入咽喉腔内后,通过往返折叠弹性体能使得密封膜5密封罩主体2与声门周围口腔粘膜的结合部。
具体地,罩体、罩体管3均采用符合医用标准的材料制成,在使用时,罩体能环绕笼罩在声门周围的口腔粘膜,一般地,罩体与罩体管3连接的端部为罩体的尾端,罩体的另一端即形成罩体的头端,罩体与罩体管3之间配合形成的形状等与现有喉罩相同,即罩体呈心形或椭圆形,罩体管3邻近罩体的区域具有折弯,利用罩体管3的折弯能便于实现供气***等操作。
本实用新型实施例中,罩体底板1、罩主体2形成罩体的结构,罩主体2设置于罩体底板1的正面上,利用罩主体2能环绕笼罩在声门周围的口腔粘膜。一般地,罩体底板1与罩主体2可采用一体成型结构,罩主体2的厚度大于罩体底板1的厚度,罩主体2、罩体底板1可采用医用硅胶等具有柔性的材料制成,从而在使用时不会对气道、声门等造成损伤。为了满足供气需要,在罩主体2内设置罩体腔10,罩体腔10位于罩主体2的中心区,罩体管3与罩体腔10连通,通过罩体管3能与呼吸机等连接,罩主体2罩在声门周围的口腔粘膜后,通过罩体管3与罩体腔10的连接配合,能形成供气通道;即利用罩体管3、罩体腔10配合进行呼吸支持的形式与现有相一致,具体过程为本技术领域人员所熟知,此处不再赘述。
为了能适应不同患者的咽喉腔,需要罩主体2具有弹性形变能力,从而在遇到略窄的咽喉腔时,利用往返折叠弹性体使得罩主体2具备弹性形变能力,且在形变后能与待置入的咽喉腔快速匹配,以便于将罩体置入咽喉腔内;将罩体置入咽喉腔的后,利用罩主体2的弹性形变能能使得罩主体2尽可能地恢复正常状态,即罩体在置入咽喉腔内后不会影响正常的呼吸支持;同时,整个置入过程中,由于采用罩主体2的弹性形变与咽喉腔配合,即不会由于 罩体的置入而导致咽喉腔的损伤。罩主体2在产生弹性形变后与咽喉腔匹配,具体是指咽喉腔能允许罩体的嵌置,且整个嵌置过程无须额外的辅助器械,即实现罩体与咽喉腔的快速匹配。
在罩体腔10的内圈上缘设置密封膜5,密封膜5的形状与罩体腔10开口的形状相一致,一般呈心形或椭圆形等,通过密封膜5能形成罩体的上表面,罩体腔10的内圈可以设置一层或多层密封膜5,具体可以根据需要进行选择,只要能利用密封膜5密封罩主体2与声门周围口腔粘膜的结合部即可。当在罩体腔10的内圈设置密封膜5后,可以省去现有的密封气囊形式。在将罩体置入咽喉腔内后,利用往返折叠弹性体的弹性形变能将密封膜5压向与口腔粘膜的结合部,从而使得能使得密封膜5密封罩主体2与声门周围口腔粘膜的结合部。

具体实施时,所述侧壁槽20的切面形状包括波浪状、M形或之字形;侧壁槽20位于罩主体2的一侧、或对称分布于罩主体2的两侧侧壁,或在罩主体2上呈U型且所述U型的底部邻近罩体管3。

当在罩体底板1的背面设置胃管槽14后,为了提高液体分泌物的吸引的便捷性,胃管槽14与侧壁槽20连通,即胃管槽14通过侧部吸引导流孔19能与侧壁槽20连通,侧部吸引导流孔19位于胃管槽14与侧壁槽20之间。侧壁槽20与侧部吸引导流孔19连通,罩主体2上的分泌物通过侧部吸引导流孔19以及侧壁槽20导流到胃管槽14,利用侧壁槽20与侧部吸引导流孔19配合能避免分泌物将侧部吸引导流孔19封堵,且又能提供罩主体2所需的弹性形变能力,提高对分泌物吸引导流的稳定性与可靠性。侧壁槽20导流后的液体通过侧部吸引导流孔19能进入胃管槽14内,吸引连接管8的头端与胃管槽14直接连通,吸引连接管8通过胃管槽14能与侧部吸引连接孔19以及侧壁槽20连通,从而通过吸引连接管8能实现将胃管槽14内以及侧壁槽20的液体吸引。所述液体一般为痰液。

本实用新型实施例中,调压管腔18与胃管槽14连通后,当调压管腔18内未有胃管嵌置时,通过调压口22的开口大小能对胃管槽14内的负压状态进行调节,即当外部负压一定时,能实现胃管槽14内的负压减少,实现减压目的。胃管槽14在罩体底板1背面贯穿所述罩体底板1的头端,从而能使得胃管能有效嵌置在胃管槽14内,并实现与胃管槽14之间的有效配合。
本实用新型实施例中,通气管腔16通过呼吸机接口7能与外部的呼吸机连接,呼吸机提供的气体能通过呼通气管腔16进入罩体腔10内,实现所需的呼吸支持。通过管体手柄6能方便拿持罩体腔3。呼吸机接口7具体可以采用与呼吸机适配的结构形式,具体为本技术领域人员所熟知,此处不再赘述。
