    • The invention relates to a suction catheter device usable with a respiratory support system which includes a catheter enveloped in a sleeve having a proximal end connector for connection to a suction source through a suction control device such as a suction control valve, and a distal end connector for attachment to a manifold of the respiratory support system. The proximal end connector includes a normally closed valve therein which prevents air flow through the catheter until a suction control device is attached thereto. The proximal end connector may also be adapted for use on a dual lumen catheter and thereby include a fluid injection passage having a one-way check valve therein. The distal end connector of the suction catheter device includes a magnifying window through which a portion of the catheter within the connector can be viewed. The catheter includes one or more markings thereon which indicate the relative position of the catheter and the connector, and which can be viewed through the magnifying window of the connector to indicate to the medical worker how far the catheter has been inserted into the patient's trachea or lungs. The invention also includes the method of assembly of the suction catheter device and the method of use thereof in conjunction with the respiratory support system.
    • 本发明涉及一种可用于呼吸支持系统的抽吸导管装置,其包括被套在套管中的导管,所述套管具有用于通过诸如吸入控制阀的抽吸控制装置连接到抽吸源的近端连接器,以及远端连接器 用于附接到呼吸支持系统的歧管。 近端连接器包括其中的常闭阀,其防止空气流过导管,直到吸入控制装置附接到其上。 近端连接器也可适用于双腔导管,从而包括其中具有单向止回阀的流体注射通道。 吸入导管装置的远端连接器包括放大窗,通过该放大窗可以观察连接器内的导管的一部分。 导管包括其上的一个或多个标记,其指示导管和连接器的相对位置,并且其可以通过连接器的放大窗口观察,以向医务工作者指示导管已经插入到患者的气管中有多远,或 肺。 本发明还包括组合吸引导管装置的方法及其与呼吸支持系统结合使用的方法。
