一种可监测肺内压的支气管封堵器
本技术涉及医疗器械
,具体是指一种可监测肺内压的支气管封堵器。
技术介绍
支气管封堵器用于胸科手术中单肺通气时的肺隔离,支气管封堵器常规的肺萎缩模式为“开胸后肺萎缩”,即在打开胸膜后封堵侧肺开始逐渐萎缩,等待肺萎缩完全后才可以进行手术,浪费大量等待时间。所以其主要缺点是封堵侧肺萎缩时间长,导致延迟手术开始时间,增加手术操作风险。因此,急需改变肺萎缩技术来加速支气管封堵器的肺萎缩速度。根据肺萎缩的主要机制,即吸收性肺不张原理,就是当高浓度氧疗时,肺泡气中氮逐渐被氧所取代,肺泡内氧弥散到肺循环中,肺泡萎缩。因此,通过纯氧通气后支气管封堵,封堵侧肺形成了一个密闭的纯氧空间,随着肺泡内氧的迅速吸收,肺泡也迅速萎缩,如果这一过程在胸膜打开前实施,就是一种与常规模式不同的“开胸前肺萎缩”模式,这样在开胸前消毒铺巾的这段时间内就可以完成肺萎缩,开胸后无需等待术者便可以进行手术,便解决了上述支气管封堵器肺萎缩时间长的问题了。但是,“开胸前肺萎缩”无法直观评估肺萎缩程度,盲目进胸时电刀或套管针会损伤肺组织,如何解决呢?前述吸收性肺不张原理中,肺泡萎缩,肺泡压力随之下降,肺萎缩的过程伴随着肺内压的减小,肺泡气吸收入血的速度越快,则肺萎缩的速度也越快,肺泡内压力减小地越快。因此,通过监测肺内压可以精准地评估开胸前肺萎缩的程度。于是,在支气管封堵器中融合压力监测系统,设计了这一款带有肺内压监测的支气管封堵器。应用这一款产品,在支气管封堵后,检测到指定肺内压力位时,说明肺萎缩已完成,便可以安全地打开胸膜实施手术。
