Abstract:
1. A catheter end closure assembly comprising a catheter adaptor including a head, a stem, a fastening segment between the head and stem and an axial passage extending the length of the adaptor; a plug including a head and a shank extending from the head, said shank being shaped and dimensioned to slidably engage in said stem and block a segment of said passage therein; an elongated cap having an open end, a closed end and a side wall extending between said ends, said cap being dimensioned to be engaged around said stem and said fastening segment so as to define between the cap and connector a closed chamber that contains the stem and plug; interfitting fastening surfaces on said cap and on said fastening segment for releasably coupling the cap to the adaptor, said interfitting surfaces comprising a resilient segment of the plug head and an interior rigid detent extending from the side wall of the cap at a location spaced from the closed end thereof, and cooperating surfaces on said plug and on said side wall which engage and interfit when the cap is coupled to the adaptor so that when the cap is subsequently decoupled from the adaptor, the plug is automatically pulled from the passage; wherein the resilient segment of the plug head defines a radial flange and is slitted lengthwise to form a plurality of spaced-apart resilient tines which may be compressed toward one another by said detent when the cap is coupled to the adaptor.
