Abstract

一种为患者提供间歇式低压通气的经口气管插管装置，其具有一经口气管插管（1），一附着在插管远端的末端气球（3），该插管包括两行与所述末端气球连通的细孔（2,5）以及一用于在吸气过程中阻止空气流动并在呼气过程中允许空气流动的单向圆阀。

Description

间歇式低压经口气管插管装置
技术领域
本报告详细介绍了一种新发明，涉及一种用于间歇式低压经口气管插管的新型装置（附图见后文）。该装置目的在于取代当前使用的为在重病监护室（ICU）接受治疗的患者或处于全身麻醉状态的外科手术患者提供其所需的人工呼吸的经口气管插管。 
由于本发明所述的间歇式低压经口气管插管装置可以取代各医院、急救医疗服务机构、私人诊所以及辅助医疗服务机构等所使用的已知型号的同类装置，因此会带来可观的商业利润。那些已经生产目前已投入使用的类似经口气管插管的公司可能会有兴趣生产本装置。 
背景技术
通常，现有的经口气管插管在其端部设有一小气球，该小气球经由患者口腔伸入患者气管。该气球借助一位于所述插管起始端的袖带（或特殊吹入器）进行充气。这种插管的缺点在于，对所述袖带随意充气所产生的压力是一非确定值，因此无法准确控制充气压力，可能会对患者造成伤害。 
所述气球的压力增量会被转移至气管壁，这样便有可能伤及患者并对气管上皮造成损伤。插管过程所用的时间越长，气管壁处于局部缺血状态的区域就越大，从而对患者气管造成的伤害也就越大。 
发明内容
本发明具有一进行间歇式低压充气的气球，这样便降低了作用在气管壁上的压力，减少了局部缺血状态并减轻了对气管上皮的伤害，从而使患者感觉更舒适并可以更好地恢复。 
附图说明
为了更清楚地描述和更好地理解本装置，下面将结合附图介绍本发明： 
图1为所述间歇式低压经口气管插管或装置（1），突出强调了其结构细节：A行细孔（5），B行细孔（2），末端气球（3）以及单向圆阀（4）； 
图2为所述充气状态的气球在机械吸气过程中的工作方式的详解图，重点在于：导引气流（F1），气管（6），末端气球（3）以及关闭的单向圆阀（4）； 
图3为所述放气状态的气球在机械呼气过程中的详解图，重点在于：导引气流（F2），气管（6），放气状态的末端气球（3）以及打开的单向圆阀（4）。 
具体实施方式
下文描述了本发明所述装置的非限制性优选制造方式，所述装置的结构和用途可依据所需型号的不同而有所不同；同时，还描述了一种用于制造本发明所述装置的可行方法及该装置的工作方式。 
本发明所述间歇式低压经口气管插管装置（1）具有一位于所述插管某一端部的末端气球（3），并且该末端气球（3）可通过间歇式控制和低压等级以关闭气管（6）。所述末端气球（3）将借助一附着到所述经口气管插管上的设备（通常为一人工呼吸装置）来完成充气，并且充气仅发生在吸气过程中。 
实现该间歇式充气方式的机构由位于所述经口气管插管末端部周围的两行细孔构成，即A行细孔（5）和B行细孔（2）。在所述插管内，一单向圆阀（4）设置于所述两行细孔（5,2）之间，该单向圆阀（4）设置成在吸气过程中阻止空气流动并在呼气过程中允许空气流动。 
在所述插管外，一固定的且具有延展性的塑料的末端气球（3）设置于所述两行细孔（5,2）的周围并将所述两行细孔包括在其内。在吸气过程中，气流穿过所述A行细孔（5），在所述气流从所述B行细孔（2）逸出之前，使所述末端气球（3）膨胀，从而到达患者的呼吸系统。 
在呼气过程中，位于所述插管内的单向圆阀（4）打开，这样，空气可以从肺部自由地流回到所述设备中。在此阶段，所述末端气球（3）中无压力，因此其为放气状态（图3）。 
这种具有间歇式流动低压气球的新型经口气管插管的使用具有诸多优点：即通过仅在吸气过程中对所述气球进行充气，使得气管壁内的血液可在辅助通气过程中流动，从而减少了对气管壁的伤害，直接减少了术后患者颈部的不适，造成伤害的风险低（例如，在重症监护室中长时间接受辅助通气治疗的患者所表现出的气管狭窄），另一重要优点在于 省去了插管过程中对气球进行充气的医疗程序；同时还省去了常规经口气管插管中的“袖带”装置以及用于对气球进行充气的注射器，从而确保了在插管操作完成后可立即进行直接而有效的通气。 
因此，基于上述结构及工作特性，可以清楚地看出，所述间歇式低压经口气管插管装置是一种新型的现代化装置，其具有新颖性、实用性、新用途、新性能以及新的改进之处，应享有实用新型专利权。
