Description

一种喉罩
技术领域
本发明涉及一种喉罩。
背景技术
在手术前，常采用喉罩向体内导入麻醉药，现有的喉罩的气囊是单层，充气后无法检测气囊与喉管是否贴合严密。当气囊与喉管贴合不严时，从主通道导入的麻醉药易漏出，从而不能控制麻醉的准确性。
发明内容
本发明要解决的技术问题是：提供一种能使气囊与喉管贴合更严实的喉罩。
为了解决上述技术问题，本发明包括导管、气囊座和气囊，导管连接在气囊座上，气囊设置在气囊座上，所述的气囊为双层气囊，包括内层气囊和外层气囊，外层气囊采用的材料比内层气囊采用的材料更易于弹性变形，所述的导管和气囊座上设有四个通道，分别为内层气囊通气通道、外层气囊进气通道、外层气囊出气通道和用于连通人体气管的主通道，内层气囊通气通道与内层气囊相连通，外层气囊进气通道与外层气囊的下侧相通，外层气囊出气通道与外层气囊的上侧相通，当内层气囊和外层气囊处于常压状态时，外层气囊与内层气囊完全贴合。
为了能直观看出是否有气体逸出，所述的导管上位于外层气囊出气通道上设有透明窗，位于通明窗内的外层气囊出气通道上有一段比外层气囊出气通道其它部分粗的检测通道，检测通道内放置有可滚动的检测球。
为了更易于观察检测球的滚动，所述的检测球的两半球壳上涂有不同的颜色。
本发明的有益效果是：本发明设置有双层气囊，外层比内层更软更易于变形，在插入喉罩后，先让内层气囊胀起，内层气囊起主要的定位和支撑作用，再让外层气囊膨胀用来弥补内层气囊作用下密封不严的地方，使气囊定位功能和密封功能都有较好的保障。使得气囊与喉管贴合更严实。

具体实施方式
如图1-4所示的一种具体实施例，它包括导管1、气囊座2和气囊3，导管1连接在气囊座2上，气囊3设置在气囊座2上，气囊3为双层气囊，包括内层气囊3-5和外层气囊3-6，内层气囊3-5比外层气囊3-6软，外层气囊3-6采用的材料比内层气囊3-5采用的材料更易于弹性变形，导管1上设有内层气囊通气通道1-3、外层气囊进气通道1-2、外层气囊出气通道1-4和用于连通人体气管的主通道1-1，气囊座2上设有内层气囊通气通道3-3、外层气囊进气通道3-2、外层气囊出气通道3-4和用于连通人体气管的主通道3-1，导管1、气囊座2上的四个通道一一对应连通，形成四个完整的通道，气囊座2上的内层气囊通气通道3-3与内层气囊3-5相连通，外层气囊进气通道3-2与外层气囊3-6的下侧相通，外层气囊出气通道3-4与外层气囊3-6的上侧相通，当内层气囊3-5和外层气囊3-6处于常压状态时，常压状态是指内外层气囊均不通气且通气口均敞开的状态，外层气囊3-6与内层气囊3-5完全贴合。
导管1上位于外层气囊出气通道1-4上设有透明窗1-6，位于通明窗1-6内的外层气囊出气通道1-4上有一段比外层气囊出气通道1-4其它部分粗的检测通道1-7，检测通道1-7内设有可滚动的检测球2-5。检测球2-5的两半球壳上涂有不同的颜色。比如一半涂成红色一半涂成白色。
工作原理：将气囊插入喉管内，再在导管的外层气囊进气通道1-2的端口和内层气囊通气通道1-3的端口各接一个送气装置，主通道1-1的端口接工作机器。先通过送气装置向内层气囊3-5中通气。达到设定气压后关闭该送气装置。再通过另一个送气装置向外层气囊3-6中通气并保压，保持压力与内层气囊3-5中气体压力相同，由于外层气囊采用的材料比内层气囊采用的材料更易于弹性变形，因此，如果外层气囊与喉管之间间隙，外层气囊会进一步发生变形贴向喉管，使得整体气囊与喉管贴合更严密，如果外层气囊出气通道3-4中有较多的气体逸出（检测球1-5滚动较快），再增加内层气囊3-5中的一定压力，使内层气囊3-5膨胀更大。使气囊3与喉管贴合更牢靠。如果外层气囊出气通道3-4中没有气体逸出或逸量小（检测球1-5不滚动或很慢），说明喉管已大部分受两层相贴合的气囊支撑，由于内层气囊3-5不易变形，因此定位作用更好一些，能保持主通道处于设置位置，不易发生偏移，此时关闭相应的送气装置和外层气囊出气通道3-4的出口，使两个气囊都处于保压状态，外层气囊会弥补内层气囊的不足，密封之前得不到气囊接触的部分喉管。不设检测球和观察窗时可采用体感或仪器来检测外层气囊出气通道3-4是否有气体逸出。
