Universal disinfection cap

1. A disinfecting cap comprising a housing, a protrusion and a cap cover, the housing comprising a top wall, an essentially cylindrical sidewall forming a first cavity, and an open bottom end opposite the top wall formed by the cylindrical sidewall with an opening to the first cavity within the housing for receiving a hub of a female needleless connector or a male needleless connector, wherein the protrusion is positioned within the first cavity and comprises an inner surface, an outer surface and an end distal the top wall of the housing, the inner surface of the protrusion defining a second cavity, and wherein the outer surface of the protrusion and an inner surface of the essentially cylindrical sidewall define a gap therebetween, and the cap cover is dimensioned and positioned to cover at least a portion of the gap between the outer surface of the protrusion and the inner surface of the housing; wherein the cap cover comprises a body comprising a top surface, an opposite bottom surface, an exterior wall and an interior wall defining an opening, and at least a portion of the interior wall is coupled or directly coupled to the protrusion and the cap cover is positioned within the housing such that the cap cover is free to deflect downward into the gap between the outer surface of the protrusion and the inner surface of the housing upon insertion of a male connector into the disinfecting cap.

2. The disinfecting cap of claim 1 , wherein the cap cover is annular.

3. The disinfecting cap of claim 1 , the cap cover comprising at least one slits formed in the cap cover body.

4. The disinfecting cap of claim 1 , wherein the cap cover is positioned between the inner surface of the essentially cylindrical sidewall proximal the open bottom end of the housing and the protrusion.

5. The disinfecting cap of claim 1 , wherein at least a portion of the exterior wall of the cap cover is coupled or directly coupled to the inner surface of the housing and the cap cover interior wall is positioned proximal to, adjacent to, directly adjacent to or abuts the outer surface of the protrusion such that the cap cover is free to deflect downward into the gap between the outer surface of the protrusion and the inner surface of the housing upon insertion of a male connector into the disinfecting cap.

6. The disinfecting cap of claim 5 , wherein the cap cover interior wall extends to or over the end of the protrusion.

7. The disinfecting cap of claim 1 , wherein at least a portion of the interior wall is coupled or directly coupled to the protrusion outer surface and/or protrusion end and the cap cover exterior wall is positioned proximal to, adjacent to, directly adjacent to or abuts the inner surface of the housing.

8. The disinfecting cap of claim 1 , the cap cover comprising at least one tab extending into the opening, wherein the at least one tab is configured and oriented to cover at least one gap in the protrusion.

9. The disinfecting cap of claim 1 , further comprising a seal disposed over the open bottom end of the housing.

10. The disinfecting cap of claim 1 , further comprising an absorbent material positioned in the housing.

11. The disinfecting cap of claim 10 , wherein the absorbent material is positioned in the second cavity and comprises a disinfectant or antimicrobial agent.

12. The disinfecting cap of claim 11 , wherein the disinfectant or antimicrobial agent is an alcohol or chlorhexidine.

13. The disinfecting cap of claim 11 , wherein the disinfectant or antimicrobial agent consists 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.

14. The disinfecting cap of claim 13 , wherein the disinfectant or antimicrobial agent comprises at least one of chlorhexidine gluconate and chlorhexidine diacetate.

15. The disinfecting cap of claim 1 , wherein the cap cover comprises a resilient material.

16. The disinfecting cap of claim 1 , wherein the cap cover is integral with the housing.

17. The disinfecting cap of claim 1 , wherein the thickness of the cap cover is from 0.1 mm to 3 mm.

18. The disinfecting cap of claim 1 wherein the thickness of the cap cover is from 0.1 mm to 2 mm.

19. The disinfecting cap of claim 1 , comprising an inner thread on the inner surface of the protrusion, the inner thread being sufficient to interlock with a mating feature of a female needleless connector.

20. The disinfecting cap of claim 1 , comprising an outer thread on the outer surface of the protrusion, the outer thread being sufficient to interlock with a mating feature of a male needleless connector.

21. The disinfecting cap of claim 1 , wherein the protrusion comprises a sidewall comprising at least one gap and at least one prong.

22. The disinfecting cap of claim 1 , wherein the protrusion is integral with the housing.

23. The disinfecting cap of claim 1 , wherein the protrusion comprises a removable insert positioned within the first cavity, the removable insert comprising a distal end comprising a distal wall, an open proximal end, and a sidewall extending proximally from the distal wall toward the open proximal end.

24. An assembly comprising the disinfecting cap of claim 1 , coupled to a medical connector.

25. The assembly of claim 24 , wherein the medical connector is selected from a male luer connector, a female luer connector, and needleless connector.
