Description

一种喉罩气囊压力检测装置及喉罩装置 技术领域
本发明涉及一种气囊压力检测装置及具有压力量化检测功能的喉罩装置， 用于检测喉罩 气囊的压力状况， 确保喉罩的安全使用。 背景技术
为了维持无意识的病人呼吸换气， 必须给其建立呼吸通道。传统的方式是使用气管插管。 但气管插管存在较大缺陷： 首先是难于快速和适当将管道插入气管， 因为这是需要很高技术 的一种处理过程， 往往还要借助喉镜等装置， 因此必须有一定技术的操作者才能实施， 就使 得这一方式在一些需要尽快在病人体内建立呼吸通道以争取治疗时间的情况 （例如危重患者 抢救等） 带来很多不便； 其次， 气管插管在使用过程中易引起病人的心肺反应、 喉咙疼痛、 咳嗽或喉痉挛等， 而且由于插入时需要控制病人的头和颈部， 使得病人颈部还可能受到伤害； 另外， 为了方便插入， 气管插管的远端尺寸必须足够小， 这就使得产生的呼吸通道较小或较 窄。
喉罩通气装置是另外一种建立呼吸通道的新型装置。 使用喉罩通气装置能较容易地插入 病人体内建立呼吸通道，一般操作者经过短期培训就能使用， 因此在急救的场合也非常适用。 由于喉罩通气装置不需要与气管敏感的内部通道相接触就可以向病人的肺充气， 因此病人受 刺激的程度大为减轻， 而且所建立的呼吸通道尺寸显著大于由气管插管所建立的呼吸通道。 同时， 由于插入时对病人头、 颈等部位的操纵动作较小， 因此对病人的潜在伤害也较小。 由 于上述的优势， 喉罩通气装置自 1983年发明以来越来越流行。
但现有的喉罩通气装置也有其缺陷： 由于喉罩使用原理是插入喉部充气后膨胀形成气囊 弹性体， 与喉腔贴合， 起到密封作用， 防止在呼吸过程中气体从喉罩与喉腔的缝隙中泄漏， 然后通过喉罩上的导管与呼吸设备连接给患者通气。 气囊一般是采用硅胶或塑胶等原料经模 具塑形制成， 再通过粘接工艺形成气囊， 如果粘接不良或材料本身气密性能不好， 在一定压 力下会造成漏气现象， 这样就无法起到密封作用， 假如这种情况不能及时发现， 就极有可能 发生医疗风险， 不能安全地给患者供气， 这就造成医护人员在选择喉罩应用时有所担忧， 不 能更广泛和长时间地使用喉罩。 发明内容 本发明所要解决的技术问题是克服现有技术中所存在的上述不足， 而提供一种喉罩气囊 压力检测装置及具有压力量化检测功能的喉罩装置， 能实时、 准确、 可靠地检测气囊的压力 状况， 让医护人员能及时发现漏气现象， 能放心长时间使用， 可以更安全、 更广泛地使用喉 为了实现上述目的， 本发明所采用的技术方案如下：
一种喉罩气囊压力检测装置， 用于实时量化检测喉罩气囊的压力， 该喉罩气囊压力检测 装置包括有一量化检测喉罩气囊压力的测压表， 该测压表与所述喉罩气囊连通； 该喉罩气囊 压力检测装置还包括有一单向阔， 所述单向阔也与所述喉罩气囊连通。

进一步的， 所述单向阀与所述充气管通过第一导管连通， 或者所述单向阀与所述充气管 一体设置。
进一步的， 所述测压表与所述充气管通过第二导管连通。

进一步的， 所述测压表为表盘指针式或数字式测压表。
本发明还公开了一种具有压力量化检测功能的喉罩装置， 包括前述任一项的喉罩气囊压 力检测装置、 以及与其连通的喉罩。
进一步的， 所述喉罩为单腔喉罩、 双腔喉罩、 三腔喉罩或三腔以上的多腔喉罩。 本发明喉罩气囊压力检测装置与现有技术相比， 该喉罩气囊压力检测装置包括有一量化 检测喉罩气囊压力的测压表， 该测压表与所述喉罩气囊连通， 可以实时、 准确、 可靠地检测 气囊的压力状况， 且气囊的压力状况能通过测压表进行量化。 另外， 本发明还配制有与喉罩 气囊连通的单向阔， 可以根据测压表检测到的压力状况对气压进行实时调整， 对气囊内的压 力进行矫正。
因此， 将本发明喉罩气囊压力检测装置与喉罩配合使用或直接使用本发明具有压力量化 检测功能的喉罩装置， 可以实时、 准确、 可靠地检测喉罩气囊的压力状况， 并及时发现漏气 或压力过大过小等不良现象， 让医护人员能长期、 长时间、 更广泛地安全使用喉罩。 附图说明
