    • A ventilating and aspirating apparatus for delivering respiratory gases to the trachea and the congested lungs and breathing passageways of a patient includes a flexible catheter tube extendable into and withdrawable from the patient's trachea. The catheter is housed within a pliable sheath extending from a manifold that is attachable to an endotracheal tube. The sheath has a slit defined by backing members formed along elongate opposed edges. A releasable, air tight "ziplock" seal is effected at the slit by a bead on one backing member and a groove to sealingly receive the bead on the other backing member. A "ziplock" actuator is structured as a slider member which travels along the bead and groove, and includes converging ends to hold the bead in the groove and a conduit member extending centrally through the slider member to interconnect an end of the catheter tube inside the sheath through a vacuum valve carried by the slider member outside the sheath to a vacuum source. The vacuum valve is operable by the same hand of a user that may be used to move the slider member.
    • 用于将呼吸气体输送到气管和拥堵的肺部以及患者的呼吸通道的通气和抽吸装置包括可延伸到患者气管中并可从患者气管中取出的柔性导管。 导管容纳在从可附接到气管插管的歧管延伸的柔韧护套内。 鞘具有由沿着细长的相对边缘形成的背衬构件限定的狭缝。 通过一个背衬构件上的凸缘和凹槽来在狭缝处实现可释放的气密“拉锁”密封,以密封地容纳另一个背衬构件上的凸珠。 “拉锁”致动器被构造为沿着胎圈和沟槽行进的滑动构件,并且包括会聚端部以将胎圈保持在槽中;以及导管构件,其中心地延伸穿过滑动构件,以将导管管的端部 护套通过真空阀将滑动件承载在护套外面到真空源。 真空阀可通过可用于移动滑动构件的使用者的手来操作。
