Abstract

A cleaning device for a medical implement is disclosed. The cleaning device includes a cap having an opening to an inner cavity, the opening being adapted to receive a site of the medical implement. The cleaning device further includes a compressible cleaning material that contains a cleaning agent prior to receipt of the site of the medical implement, i.e. the cleaning material is pre-loaded with the cleaning agent. The compressible cleaning material is at least partially secured in the inner cavity and adapted to swab and clean the site with the cleaning agent.

a threaded ring connected to the inner cavity at the opening to the cap, and having threads that correspond to threads on the threaded medical implement;

a cleaning material in the inner cavity adapted to provide radial compression against the threaded medical implement, the cleaning material containing a cleaning agent prior to receipt of the site of the medical implement; and

one or more vent holes between the threaded ring and the inner cavity at the opening to the cap, the one or more vent holes to permit drying the cleaning agent and to inhabit a vacuum in the inner cavity to support mechanical tension by the threads on the threaded medical implement.

6. A cleaning system in accordance with claim 5, wherein the cleaning material is further adapted to provide axial compression against the threaded medical implement.

7. A cleaning system in accordance with claim 5, wherein the cap and the threaded ring are formed of a unitary piece of material.

8. A cleaning system in accordance with claim 6, wherein the cleaning material is formed of a first cleaning material to provide the radial compression against the threaded medical implement, and a second cleaning material to provide the axial compression against the threaded medical implement.

9. A cleaning system in accordance with claim 5, wherein the cleaning agent includes isopropyl alcohol.

10. A cleaning system in accordance with claim 5, wherein the cap includes an outer surface having a plurality of vertical ridges.

11. A cleaning system in accordance with claim 5, further comprising a removable seal connected to the lower edge of the cap to cover the opening to the inner cavity.

12. A method of cleaning a site of a medical implement, the method comprising:

at least partially saturating a cleaning material with a cleaning agent in an inner cavity of a cap that includes an opening to the inner cavity and at least one other aperture to the inner cavity the cap further including a removable seal that encloses the opening and the at least one other aperture;

removing the seal from the opening and the at least one other aperture;

contacting a top of the site of the medical implement to a first portion of the cleaning material;

compressing the first portion of cleaning material with the site of the medical implement to contact the site with the cleaning agent in the cleaning material provided around the first cleaning material;

attaching the cap over the top of the site of the medical implement; and

evaporating the cleaning agent through the at least one other aperture to the inner cavity as the cap is attached over the top of the site.

13. A cleaning device for a medical implement, the cleaning device comprising:

a cap having a first opening to an inner cavity, an inner surface of the first opening including one or more threads adapted to receive a site of the medical implement;

a cleaning material formed of a compressible material that is at least partially secured in the inner cavity, the cleaning material containing a cleaning agent;

a second opening in the cap to allow evaporation of the cleaning agent from the inner cavity and to inhibit a buildup of pressure in the cap when the cleaning material is compressed by the site of the medical implement and a removable covering that covers the first opening and the second opening to the inner cavity prior to coupling the threads of the cap with the site of the medical implement via the first opening.

14. A cleaning device in accordance with claim 13, wherein the cleaning material is adapted to provide radial compression against the site of the medical implement for radial swabbing of the site.

15. A cleaning device in accordance with claim 13, wherein the cleaning

material is adapted to provide axial compression against the site of the medical implement for axial and rotational swabbing of the site of the medical implement when the site is rotated into the first opening of the cap.

16. A cleaning device in accordance with claim 13, wherein the compressible material includes an open-cell foam.

17. A cleaning device in accordance with claim 13, wherein the cleaning material includes a first cleaning material to provide the radial compression against the site of the medical implement, and a second cleaning material to provide the axial compression against the site of the medical implement.

18. A cleaning device in accordance with claim 13, wherein the cleaning material is preloaded with the cleaning agent prior to a seal being applied to the first and second openings of the cap.

19. A cleaning system for a medical environment, the cleaning system comprising:

a plurality of caps, each cap having;

an inner cavity and an opening to receive a site of the medical implement into the inner cavity; and

a cleaning material in the inner cavity adapted to provide axial compression against a site of a medical implement, the cleaning material containing a cleaning agent prior to receipt of the site of the medical implement; and

a threaded ring connected to the inner cavity at the opening to the cap, the threaded ring having threads that correspond to threads on the medical implement; and

at least one evaporation vent in a wall of the cap between the threaded ring and the inner cavity at the opening to allow evaporation of the cleaning agent upon receipt of the site of the medical implement; and
