A suction catheter assembly has an aspirating catheter (1) that is enclosed along its length within a protective sleeve (2). The catheter (1) extends from a vacuum connecting member (3), which is connected to a suction source (5), and a patient connecting member (4, 4'), which is coupled to a tracheal tube (7) and has two side ports (46, 47) connected to ventilation equipment. A one-way valve (50, 60, 102) in the patient connecting member (4, 4') allows trapped gas in the sleeve (2) to escape into the patient connecting member when the catheter (1) is advanced. <IMAGE> |
