Description

一种特制的气管切开重症患者使用的吸氧湿化装置 技术领域
本申请涉及气道湿化装置的领域，尤其是涉及一种特制的气管切开重症患者使用的吸氧湿化装置。
背景技术
重症监护学是近20年建立并发展起来的临床医学独立分支学科。随着中国老龄化程度的加剧，ICU的作用也越发受到重视。一些患者在送至ICU,特别是开胸、开腹、开颅等大手术后，基本处于昏迷不能自理状态，相当一部分患者在抢救过程中作了气管切开手术，做好气管切开患者的管道护理，是重症患者护理之中一项必不可少的重要项目。
气管插管或气管切开脱机的患者，呼吸道粘膜丧失了对吸入气体的加温和湿化作用，同时由于气道开放，患者呼吸道失水增加，导致痰液粘稠不易咳出，甚至干结成痰痂，导致呼吸系统感染甚至堵塞呼吸道，患者缺氧加重甚至窒息，不利于疾病恢复。所以对气管切开患者的气道管理显得十分重要，其中最主要的一部分是有效气道湿化。
传统的方法采用纯净水滴入纱布的方式，但这种方式存在很多弊端，比如控制不好水流滴速，过快容易引起过多水分进入气道呛入气管和肺部，过慢又容易导致湿化效果不足，痰痂形成从而阻塞气道。而且目前气管切开呼吸机脱机锻炼的危重病人常规会给予氧气管放入气切导管处，跟雾化管道不同步，相对杂乱。因此，一些呼吸器官的疾病和脑中风自主吞咽功能的气切危重患者在目前的吸氧及湿化条件下易产生一系列并发症影响疾病预后及康复治疗。
