ABSTRACT:
A medical connector assembly comprises a connector body having a fluid passage there through, a valve member, and means, responsive to a compressive force placed on the medical connector, for permitting a fluid to freely communicate between openings in the connector body. The valve member can be constructed using a single element having a slit therein or it can be constructed using two separate halves which when joined together form an interface slit. In a preferred embodiment, when a compressive force is exerted against the connector body, sufficient distortion is experienced by the valve member to open the slit and permit fluid flow between connector body openings.
