Abstract:
1. A medical connector comprising: a housing with a central axis and a hollow bore having a male end with a male luer tip and a female end; a valve member configured to at least partially extend into an interior space of the male luer tip, the valve member comprising a first opened end, a second end, an internal passageway, at least one opening near the second end of the valve member extending through the valve member and into the passageway; an internal conduit having a fluid passageway and being in fluid communication with the female end; the internal conduit interfacing with the first opened end of the valve member and configured to minimize leakage of fluid out of a fluid path formed by the internal passageway of the valve member and the fluid passageway of the internal conduit, the internal conduit and the first opened end of the valve member being moveable relative to each other along the central axis such that at least a portion of the valve member and the internal conduit overlap, thereby producing a change in volume in an interior region of the housing as the valve member moves from a first position to a second position, the volume of the interior region being larger in the first position than in the second position; a resilient member configured to couple the valve member and the housing and to bias the valve member against the male luer tip to close said medical connector, said resilient member circumferentially engaging the housing and configured to stretch as said medical connector moves from a closed position to an open position.
