ABSTRACT:
Closed system, combined suction and ventilation medico-surgical tube devices include (1) a suction catheter, (2) a suction control valve positioned at the distal end of the system, (3) a multi-port coupling unit through which the catheter is fed for aspiration of a patient, (4) a flexible tubular sheath providing a sterility protective enclosure for the catheter fixed at its distal end to the proximal end of the coupling unit and (5) a sheath relief valve. The coupling units (4) have two separate members, one of which is fitted axially into the other so they may rotate relative to each other about their longitudinal axes to close and open access of the catheter from the sheath through the coupling unit into the patient. The suction control valves (2) have first and second substantially identical parts positioned together along a longitudinal side in sliding engagement with each other for movement between an open and a closed position of the valves. The sheath relief valves (5) serve to prevent air in the sheath from becoming contaminated during use of the assembly.
