Abstract

A device for connection to a medical connector, the device includes a cap having an annular wall having an exterior wall surface and an interior wall surface including a plurality of inwardly extending protrusions sized and shaped to frictionally engage a male luer, and a peelable seal. The cap configured to define a chamber to contain an absorbent material and disinfectant or antimicrobial agent. The cap includes one or more threads adapted to engage with a female luer connector. The cap is adapted to engage a male luer connector in a press-fit connection. The peelable seal prevents the disinfectant or the antimicrobial agent from exiting the chamber. Also described are methods of disinfecting a medical connector, and apparatuses comprising a device for disinfecting a medical connector.

First claim

What is claimed is:

1 . A method of disinfecting a medical connector, the method comprising:
connecting a device having a cap comprising an integral body, a closed end, an annular wall having a length LB extending from the closed end to an open end and defining a chamber containing an absorbent material and disinfectant or antimicrobial agent, the open end defining an end face, the open end defining an engagement surface; the annular wall having an exterior wall surface and an interior wall surface comprising a plurality of inwardly extending protrusions sized and shaped to frictionally engage a male luer connector or a female luer connector; the interior wall surface comprising internal threads adjacent the closed end, the internal threads adapted and sized to engage a female luer connector, wherein connecting comprises frictionally engaging the interior wall surface upon insertion into the chamber such that the medical connector contacts the absorbent material and the disinfectant or antimicrobial agent.

2 . The method of claim 1 , wherein the female luer connector is selected from the group consisting of needle-free connectors, catheter luer connectors, stopcocks, and hemodialysis connectors.

3 . The method of claim 1 , wherein the male luer connector is an intravenous tubing end, stopcock, or male lock luer.

4 . The method of claim 3 , wherein the step of connecting further comprising mounting the cap onto the male luer connector by frictionally engaging the male luer connector to the inwardly extending protrusions on the interior wall surface via a press-fit connection upon insertion into the chamber.

5 . The method of claim 4 , wherein insertion of a collar of a male connector dilates the opening defined by the plurality of inwardly extending protrusions from an initial diameter of from about 7-9 mm to a dilated diameter of about 9-12 mm to accept the male connector.

6 . The method of claim 5 , further comprising applying force to the plurality of inwardly extending protrusions by inserting the male luer connector into the open end of the cap to deform or displace the plurality of inwardly extending protrusions around the male luer connector to nest the male luer connector.

7 . The method of claim 6 , further comprising inserting the male luer connector into the chamber to contact and rest on the peripheral ledge upon being fully inserted in into the chamber.

8 . The method of claim 7 , further comprising compressing the absorbent material toward the closed end of the chamber upon connection to the male luer connector to release the disinfectant or antimicrobial agent to contact and disinfect the male luer connector.

9 . The method of claim 2 , wherein the step of connecting further comprising mounting the cap onto the female luer connector by inserting the female luer connector into the opening of the chamber to contact the internal threads.

10 . The method of claim 6 , further comprising screwing the female luer connector onto the internal threads to engage the internal threads.

11 . The method of claim 7 , further comprising screwing the female luer connector onto the internal threads creating a fluid tight seal.

12 . The method of claim 8 , further comprising compressing the absorbent material toward the closed end of the chamber upon connection to the female luer connector to release the disinfectant or antimicrobial agent to contact and disinfect the female luer connector.
