Abstract

The present disclosure is directed to a flexible cap for a medical fitting, such as a luer-lock fitting. The flexible cap includes a cap component defining a top surface, a cylindrical wall extending opposite from the top surface of the cap component, and an inner sealing surface. The cylindrical wall defines a hollow interior configured to receive an internal tapered sealing wall of a male connector of the medical fitting so as to form a seal with an outer surface of the tapered sealing wall. Further, the inner sealing surface of the flexible cap is configured within the hollow interior. Thus, when the tapered sealing wall of the male connector of the medical fitting is received within the hollow interior of the cylindrical wall, the inner sealing surface of the flexible cap seals the fluid passageway of the tapered sealing wall.

First claim

What is claimed is:

1. A flexible cap for a male connector of a medical fitting, the male connector having an outer locking collar and an internal tapered sealing wall that defines an internal cavity therebetween, the outer locking collar of the male connector comprising internal threads, the internal tapered sealing wall defining a fluid passageway, the flexible cap being a push-in cap, the push-in cap comprising:
a cap component defining a top surface;
a cylindrical wall extending opposite from the top surface of the cap component, the cylindrical wall defining a hollow interior configured to receive the internal tapered sealing wall of the male connector so as to form a seal with an outer surface of the internal tapered sealing wall, wherein the cylindrical wall is expandable, wherein the cylindrical wall further comprises at least one rib on an exterior surface thereof, wherein the at least one rib is configured to engage the internal threads of the outer locking collar of the male connector when the cylindrical wall expands; and
an inner sealing surface configured within the hollow interior, wherein, when the internal tapered sealing wall of the male connector of the medical fitting is received within the hollow interior of the cylindrical wall, the inner sealing surface seals the fluid passageway of the internal tapered sealing wall.

2. The flexible cap of claim 1 , wherein the inner sealing surface comprises a protrusion configured to fit at least partially within the fluid passageway so as to seal the fluid passageway.

3. The flexible cap of claim 2 , wherein the protrusion comprises a dome configured to fit at least partially within the fluid passageway so as to seal the fluid passageway.

4. The flexible cap of claim 2 , wherein the protrusion comprises a hollow cross-section.

5. The flexible cap of claim 4 , wherein the hollow cross-section extends from the top surface of the cap component so as to define an open recess on the top surface of the cap component.

6. The flexible cap of claim 1 , wherein the medical fitting comprises a leer-lock fitting.

7. The flexible cap of claim 1 , wherein the at least one rib comprises opposing ribs on opposite sides of the cylindrical wall.

8. The flexible cap of claim 1 , further comprising a tether.

9. The flexible cap of claim 8 , wherein the tether is integral with the cap component.

10. The flexible cap of claim 1 , wherein the cap component further comprises a pull tab.

11. The flexible cap of claim 1 , wherein the flexible cap is constructed from at least one of polyurethane, neoprene, synthetic rubber, latex, or silicone.

12. The flexible cap of claim 1 , wherein the at least one rib is configured to provide tactile feedback when the push-in cap is inserted within the internal cavity of the male connector.
