ABSTRACT OF THE INVENTION Suction catheter assemblies have an aspirating catheter that is enclosed along its length within a protective sleeve. The catheter extends from a vacuum connecting member, which can be connected to a suction source, to a patient connecting member, which has a coupling for connection to a tracheal tube and two side ports for connection to ventilation equipment. In the present invention, a one-way valve in the patient connecting member allows trapped gas in the sleeve to escape into the patient connecting member when the catheter is advanced.
