Abstract
A suction catheter assembly has 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, and a patient connecting member which has a coupling for connection to a tracheal tube and two side ports for connection to ventilation equipment. A one-way valve in the patient connecting member forms a sliding seal with the catheter and allows trapped gas in the sleeve to escape into the patient connecting member when the catheter is advanced.
