    • An endotracheal tube assembly (10) is disclosed which suctions away bacteria multiplying mucus before such mucus can accumulate on the inside walls of the endotracheal tube (14). In the preferred embodiment, one or more suctioning tubes (20, 21) are formed into the walls of an endotracheal tube so that they extend along length of the endotracheal tube. A plurality of mucus slurping holes (34) are then formed at or near the distal end of the endotracheal tube and connected to the suctioning tubes. In operation, suctioning through the mucus slurping holes is preferably performed intermittently during patient expiration. By timing this intermittent suctioning with patient expiration, the suctioning flow will be in the same direction as patient breathing. While the mucus slurper of the present invention has been found to be effective at keeping the inner walls of the endotracheal tube free of mucus deposits, it can nonetheless be combined with other cleaning and disinfectant techniques for greater assurance of cleanliness.
    • 公开了一种气管内管组件(10),其在这样的粘液可能积聚在气管内管(14)的内壁上之前吸收细菌使粘液变脏。 在优选实施例中,一个或多个抽吸管(20,21)形成在气管内管的壁中,使得它们沿着气管插管的长度延伸。 然后在气管内管的远端处或附近形成多个粘液淤泥孔(34),并连接到抽吸管。 在操作中,优选在患者呼气期间间歇地进行通过粘液淤泥孔的抽吸。 通过定时这种间歇性吸入与患者呼气,吸入流量将与患者呼吸方向相同。 虽然已经发现本发明的粘液淤泥在保持气管内管的内壁没有粘液沉积物方面是有效的,但是它仍然可以与其它清洁和消毒技术组合以更好地保证清洁。

    • An endotracheal tube cleaning apparatus (10) which can be periodically inserted into the inside of an endotracheal tube (30) to shave away mucus deposits. In a preferred embodiment, this cleaning apparatus (10) comprises a flexible central tube (12) with an inflatable balloon (40) at its distal end. Affixed to the inflatable balloon are one or more shaving rings (70), each having a squared leading edge (72) to shave away mucus accumulations (60). In operation, the uninflated cleaning apparatus (10) of the present invention is inserted into the endotracheal tube until its distal end is properly aligned with or slightly beyond the distal end of the endotracheal tube. After proper alignment, the balloon (40) is inflated by a suitable inflation device, such as a syringe (14), until the balloon's shaving rings are pressed against the inside surface of the endotracheal tube. The cleaning apparatus is then pulled out of the endotracheal tube and, in the process, the balloon's shaving rings shave off the mucus deposits from the inside of the endotracheal tube. The cleaning apparatus of the present invention can advantageously be used with endotracheal tubes having bactericidal films on the tubes' inside walls.
    • 气管内管清洁装置(10),其可以周期性地插入到气管内管(30)的内​​部以刮除粘液沉积物。 在优选实施例中,该清洁装置(10)包括在其远端具有可膨胀气囊(40)的柔性中心管(12)。 与充气气囊相连的是一个或多个剃须环(70),每个剃须环具有平方的前缘(72)以刮去粘液积聚物(60)。 在操作中,将本发明的未充气清洁装置(10)插入到气管内管中,直到其远端适当地对准或稍微超过气管内管的远端。 在正确对准之后,气球(40)通过适当的充气装置(例如注射器(14))充气,直到球囊的剃须环压在气管内管的内表面上。 然后将清洁装置从气管内管中拉出,并且在该过程中,气球的剃刮环从气管内管内部刮去粘液沉积物。 本发明的清洁装置可有利地与管内壁上具有杀菌膜的气管内管一起使用。
