Medical connector with closeable male luer
View Patent ↗A luer connector comprising a housing with a hollow bore having first and second ends, a male luer tip, and a tapering interior surface. The luer connector also comprises a rigid valve member having a first opened end and a second closed end, a passageway therein, and an outwardly extending flange near the second end adapted to seal the hollow bore at the second end of the housing when in contact with an interior surface of the housing. The valve member further comprises an 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. 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 to inhibit fluid communication through the hollow bore of the housing.
1. A luer connector comprising:
a housing with a hollow bore having a first end and a second end including a male luer tip with a tapering interior surface at the narrow end of the luer tip;
a valve member configured to at least partially extend through the housing, the valve member having a first opened end and a second end and comprising:
a passageway within the valve member;
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 the tapering interior surface of the male luer tip;
at least one opening near the second end of the valve member extending outwardly from the passageway through the valve member to place the interior of the male luer tip in fluid communication with the passageway;
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;
a resilient member configured to couple the valve member and the housing and to bias the valve member against the tapering interior surface of the male luer tip to close said luer connector, said resilient member circumferentially engaging the housing and configured to stretch as said luer connector moves from a closed position to an open position; and
wherein said opened end of said valve member is in fluid communication with the first end of the housing in both the open and closed positions of the luer connector.
2. The luer connector of claim 1 , wherein the resilient member engages the housing at a position between the male luer and the first end of the housing.
3. The luer connector of claim 1 , wherein the resilient member engages the outside of the housing.
4. The luer connector of claim 1 , wherein the valve member is flexible.
5. The luer connector of claim 1 , wherein the valve member is rigid.
6. The luer connector of claim 1 , wherein the resilient member is integrated into the valve member.
7. The luer connector of claim 1 , wherein the struts are approximately planar.
8. The luer connector of claim 1 , wherein the passageway has a varying diameter between the first and second ends of the valve member.
9. The medical connector of claim 1 , wherein the connector includes a shroud having a plurality of depressions.
10. The luer connector of claim 9 , wherein an outer surface of the housing adjacent the shroud is approximately co-planar with surfaces of the depressions.
