Abstract: A connector for openly connecting conduits includes male and female parts adapted to couple by plug fit connection and structured to permit relative rotational displacement in coupled condition.

Abstract: A modular ventilating/aspirating assembly includes a catheter subassembly, including a sputum trap; an optional valved manifold and a suction control valve with an actuator oriented at an acute angle with respect to the lumen of the valve. The suction control valve includes a connection end which may couple selectively to a catheter subassembly or to other peripheral devices.

Abstract: A manifold assembly useful in patient ventilation/aspiration systems includes a stop cock valve with a hollow stem and a transverse slot arranged to permit the stem to be rotated between open and closed positions. In both positions, a ventilating pathway is maintained through the slot and the stem between ventilator and patient connection ports of the manifold. In open position the stem provides a travel pathway for a catheter between the patient connection port and an access port of the manifold. In closed condition, the stem seals this travel pathway.

Abstract: A selectively positionable fluid conduit for gas removal from or gas introduction to a specific environment is disclosed. The fluid conduit includes a tubular wand having an orifice at the distal end thereof. Unwanted gases are removed by suction force through the orifice. Desirable or therapeutic gases are introduced to a specific location through the orifice. The tubular wand is coupled to a malleable positioning tube. The malleable positioning tube can be manipulated into various configurations such that the positioning tube maintains the last chosen configuration. In one disclosed embodiment, the malleable positioning tube includes tubular bellows formed from a plurality of alternating large and small diameter rings joined by frusto-conical walls. In another embodiment, the malleable positioning tube includes a malleable wire associated with a semi-rigid tube. Interaction between the rings and the frusto-conical walls imparts malleable properties to the positioning tube.
