A luer connector comprising a housing with a hollow bore having first and second ends. The hollow bore also has a male luer tip and a tapering interior surface. The luer connector also comprises a rigid valve member configured to at least partially extend through the housing. The valve member has a first opened end and a second closed end. The valve member also comprises a passageway within the valve member and an outwardly extending flange near the second end adapted to seal the hollow bore at the second end of the housing when placed in contact with a tapering interior surface of the housing. The valve member further comprises at least one opening near the closed end of the valve member extending outward from the passageway through the valve member and at least one strut attached to the valve member. At least a portion of the strut extends substantially parallel to the central axis of the valve member. The luer connector also comprises a retaining member configured to couple the valve member and the housing and a sealing element disposed within the housing. The sealing element is configured to inhibit fluid communication through the hollow bore of the housing between the interior of the male luer tip of the housing and the first end of the housing.

1. A luer connector, comprising: a housing having a hollow bore having a first end, a second end, and a male luer tip with a tapering interior surface;a rigid valve member configured to at least partially extend through the housing, the valve member comprising: a first open end;a second closed end;a passageway within the valve member;at least one opening near the closed end of the valve member extending outwardly from the passageway through the valve member;at least one strut attached to the valve member, at least a portion of the strut extending substantially parallel to the central axis of the valve member; anda resilient retaining member configured to couple the valve member and the housing;wherein: the first open end of the valve member extends past a first end of the housing in a direction away from the closed end of the valve member such that at least a portion of the first open end of the valve member is positioned outside of the housing; andthe valve member is manually movable relative to the housing between an open position and a closed position. 2. The connector of claim 1, wherein the valve member is openable by moving the open end of the valve member away from the first end of the housing, thereby allowing fluid to flow through the passageway within the valve member. 3. The connector of claim 2, wherein moving the open end of the valve member away from the first end of the housing moves the closed end of the valve member away from the second end of the housing, thereby allowing fluid to flow through the passageway within the valve member. 4. The connector of claim 1, wherein the valve member is openable by moving a male luer tip of a medical implement engaged with the open end of the valve member away from the first end of the housing, thereby moving the valve member to an open position and allowing fluid to flow through the passageway within the valve member. 5. The connector of claim 1, wherein the rigid valve member comprises an outwardly extending flange near the second end of the valve adapted to seal the hollow bore at the second end of the housing when placed in contact with a tapering interior surface of the housing. 6. The connector of claim 1, further comprising screw threads or other external engaging features projecting from an outside surface of the first open end of the valve member. 7. The connector of claim 1, wherein the valve member is manually openable to prime the luer connector. 8. The connector of claim 1, further comprising a sealing element disposed within the housing configured to inhibit fluid communication through the hollow bore of the housing between an interior of the male luer tip of the housing and the first end of the housing. 9. The connector of claim 8, wherein the sealing element has a body portion, at least one ring portion generally coaxially aligned with the body portion, and at least one protrusion extending from an outside wall of the body portion. 10. The connector of claim 9, wherein the sealing element is configured such that the ring portion is positioned at an end portion of the body portion. 11. The connector of claim 1, wherein the resilient member is configured to bias the valve member toward the second end of the housing while permitting the valve member to displace toward the first end of the housing when an opening force is applied to the luer connector. 12. The connector of claim 11, wherein the force is applied to either the second closed end of the valve member or the at least one strut attached to the valve member. 13. The connector of claim 11, wherein the force is applied to the first open end of the valve member. 14. The connector of claim 1, wherein the resilient member has at least two interconnected rings interconnected by at least one elastic member. 15. The connector of claim 14, wherein at least one of the rings is supported on the outside of the housing and at least one of the rings is supported by the valve member. 16. The connector of claim 1, wherein one or more depressions are formed in an outside surface of the housing, the depressions being sized and configured to assist a user in grasping and/or twisting the housing with his or her fingers. 17. The connector of claim 1, comprising a section of tubing attached to the open end of the valve member. 18. A method of opening a valve member in a luer connector having a male luer tip, comprising: grasping a housing having a first end and a second end, wherein the male luer tip has a hollow bore axially therethrough and is positioned at or near the second end of the housing;connecting a medical implement to an open end portion of the valve member, the valve member being supported partially within the housing such that the open end portion of the valve member extends past the first end of the housing so as to be positioned outside of the housing and a first closed end of the valve member extends into an inner portion of the male luer tip; andopening the valve member to permit fluid to flow through a passageway extending through the valve member and through the male luer tip by moving the valve member away from the second end of the housing so that the closed end of the valve member moves away from an opening in the end of the male luer tip. 19. The method of opening a valve member in a luer connector of claim 18, wherein moving the valve member away from the second end of the housing comprises pulling on the open end portion of the valve member so as to manually move the open end portion of the valve member away from the first and second ends of the housing. 20.
