Abstract

A device for connection to a medical connector, the device includes a cap, a container 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.

First claim

What is claimed is:

1. A device for connection to a medical connector, the device comprising:
a cap comprising a closed end, an annular wall having a length 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 having a peripheral ledge extending radially from the open end defining an engagement surface;
the annular wall having a frustoconical shape and further having an exterior wall surface and an interior wall surface;
the interior wall surface defining an opening adjacent to the open end, the opening sized and adapted to receive a male luer connector, a female luer connector and a hemodialysis connector, the interior wall surface extending from the open end to the peripheral edge having a smooth interior wall surface leading to the peripheral ledge, wherein the male luer connector frictionally engages the interior wall surface via a press-fit connection upon insertion into the chamber and the wherein the male luer connector rests on the peripheral ledge upon being fully inserted into the chamber;
the interior wall surface of the peripheral ledge leading to a portion of the interior wall surface comprising internal threads adjacent the closed end partially extending along a length of the interior wall surface, the internal threads adapted and sized to engage a female luer connector, the absorbent material and the disinfectant or the antimicrobial agent capable of contacting the male luer connector, the female luer connector and the hemodialysis connector;
the exterior wall surface comprising a plurality of radial protrusions;
a container comprising an annular container wall having a container wall length extending from a container closed end to a container open end face, the container having an interior container surface and an exterior container surface, the container housing the cap, the container having a complementary plurality of depressions that engage the plurality of radial protrusions; and
a peelable seal on the container open end face to prevent the disinfectant or the antimicrobial agent from exiting the chamber.

2. The device of claim 1 , wherein the female luer connector comprises a needle-free connector, stopcocks, or hemodialysis connector.

3. The device of claim 1 , wherein the male connector comprises an intravenous tubing end or stopcock.

4. The device of claim 1 , wherein the opening adjacent to the open end of the interior wall surface is sized and adapted to receive a male luer connector in a press-fit connection.

5. The device of claim 1 , wherein the cap comprises an elastomeric material.

6. The device of claim 5 , wherein the elastomeric material comprises a thermoplastic elastomer.

7. The device of claim 1 , wherein the exterior container surface includes a plurality of grip members.

8. The device of claim 1 , wherein the container comprises a polypropylene or polyethylene material.

9. The device of claim 1 , wherein the annular container wall is frusto-conically shaped.

10. The device of claim 1 , wherein the absorbent material is a foam.

11. The device of claim 10 , wherein the foam is a polyurethane foam.

12. The device of claim 1 , wherein the absorbent material is a sponge.

13. The device of claim 1 , wherein the absorbent material is compressible.

14. The device of claim 13 , wherein compression of the absorbent material disinfects the female luer connector or the male luer connector.

15. The device of claim 1 , wherein the absorbent material is under radial compression by the internal threads to retain the absorbent material in the chamber.

16. The device of claim 1 , wherein the disinfectant or antimicrobial agent is selected from the group consisting essentially of isopropyl alcohol, ethanol, 2-propanol, butanol, methylparaben, ethylparaben, propylparaben, propyl gallate, butylated hydroxyanisole (BHA), butylated hydroxytoluene, t-butyl-hydroquinone, chloroxylenol, chlorohexidine, chlorhexidine diacetate, chlorohexidine gluconate, povidone iodine, alcohol, dichlorobenzyl alcohol, dehydroacetic acid, hexetidine, triclosan, hydrogen peroxide, colloidal silver, benzethonium chloride, benzalkonium chloride, octenidine, antibiotic, and mixtures thereof.

17. The device of claim 16 , wherein the disinfectant or antimicrobial agent comprises at least one of chlorhexidine gluconate and chlorhexidine diacetate.

18. The device of claim 1 , wherein the disinfectant or antimicrobial agent is a fluid or a gel.

19. The device of claim 1 , wherein the peelable seal comprises an aluminum or multi-layer polymer film peel back top.

20. The device of claim 1 , wherein the peelable seal is heat-sealed or induction sealed to the container open end face to retain the cap within the container.

21. The device of claim 1 , wherein the cap is selectively coupled to the container via a keyed connection.

22. The device of claim 21 , wherein the keyed connection comprises one or more depressions of the container configured to be selectively coupled to a plurality of radial protrusions on the cap.

23. The device of claim 1 , wherein the cap is selectively coupled to the container via a slip-fit connection.

24. The device of claim 23 , wherein the plurality of depressions of the container selectively coupled the plurality of radial protrusions of the cap via a slip-fit connection.

25. The device of claim 1 , wherein the plurality of radial protrusions extend along an entire length of the exterior wall surface of the cap and the plurality of depressions extend along an entire length of the interior container surface.

26. The device of claim 1 , wherein the plurality of radial protrusions partially extend along the length of the exterior wall surface of the cap and the plurality of depressions partially extend along the length of the interior container surface.

27. The device of claim 1 , wherein the plurality of radial protrusions and the plurality of depressions are elongate.

28. The device of claim 1 , wherein the plurality of radial protrusions and the plurality of depressions are tapered.

29. A method of disinfecting a medical connector, the method comprising: connecting the device of claim 1 to a medical connector, wherein connecting includes 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.

30. An assembly comprising:
a connector of claim 1 connected with one of a male luer connector, a female luer connector, a needleless connector.
