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 medical fitting for a medical device, the fitting comprising:
a male connector comprising an outer locking collar and an internal tapered sealing wall, the outer locking collar and the internal tapered sealing wall defining an internal cavity therebetween, the internal cavity configured to receive a female connector during use, the internal tapered sealing wall defining a fluid passageway therethrough; and
a flexible cap configured to fit within the male connector when not in use, the flexible cap comprising:
a cap component defining a top surface, the top surface defining a first open recess,
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, and
an inner sealing surface comprising an integral dome-shaped protrusion configured to fit at least partially within the fluid passageway so as to seal the fluid passageway, the integral dome-shaped protrusion comprising a hollow cross-section that extends from the first open recess defined in the top surface to a distal end of the integral dome-shaped protrusion so as to define a second open recess that connects to the first open recess, 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 medical fitting of claim 1 , wherein the outer locking collar of the male connector comprises at least one of internal threads or external threads.

3. The medical fitting of claim 2 , 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 at least one of internal threads or external threads.

4. The medical fitting of claim 1 , further comprising a tether.

5. The medical fitting of claim 4 , wherein the tether is integral with the cap component.

6. The medical fitting of claim 1 , wherein the medical fitting comprises a luer-lock fitting.

7. The medical fitting of claim 1 , wherein the cylindrical wall further comprises opposing ribs on opposite sides thereof.

8. The medical fitting of claim 1 , wherein the cap component further comprises a pull tab.

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