ABSTRACT:
A combination quick disconnect coupling and fluid cutoff valve particularly adapted for use in continuous ambulatory peritoneal dialysis comprises a first tubular member connected to a length of flexible tubing and having a fluid passageway therethrough, and a second tubular member connected to a second length of flexible tubing and constructed for telescopic reception of the first tubular member. A rotatable sleeve is disposed within the first tubular member (partially closed at a first end). By rotating the sleeve the fluid passageway may be selectively opened or closed. A coupling mechanism, such as a bayonet lock is used for retaining the first and second tubular members together. A series of lugs extend inwardly from the second tubular member and are arranged to engage the rotatable sleeve as the first tubular member is inserted into the second tubular member, so as to advance the movable sleeve to an open position during coupling thereby opening the fluid passageway. Finally, a resilient sealing mechanism is used for hermetically sealing the connection between the first and second members.
