Abstract

A device for cleaning medical implements is disclosed, in particular a device for cleaning vascular or other fluid access sites. The device includes a cap having an opening to receive an access site. The cap may be used in the following manner: A healthcare worker may, with gloved hands, open the cap packaging and place the cap over the port of a medical implement to be cleaned. The healthcare worker may wipe the site by either applying a turning motion or by simply pushing the cap onto the port. The cap could then remain secured in place by threads other mechanisms. A cap in place on a medical implement may be a positive indication that a desired site of the medical implement is clean. The cap may include a disinfecting substance.

Claims (40)

1. A disinfecting cap and syringe system comprising:

a syringe comprising:

a barrel; and

a plunger having a plunger shaft comprising a rib and a thumb pad; and

a disinfecting cap comprising:

an open end;

a closed end;

an exterior surface comprising: a peripheral surface adjacent the open end, a bottom surface adjacent the closed end, and a side surface extending between the open end and the closed end;

a cavity adjacent to the open end to receive an access site, the cavity comprising a bottom surface and sidewall; and

an aperture adjacent to the disinfecting cap exterior surface bottom surface, the aperture being sized to accept the syringe plunger thumb pad, and the aperture comprising a slot that accommodates the rib of the syringe plunger shaft;

wherein the disinfecting cap is removeably attached to the syringe by lateral movement of the aperture over the thumb pad.

2. The disinfecting cap and syringe system of claim 1 , wherein the disinfecting cap has a square cross-section.

3. The disinfecting cap and syringe system of claim 1 , wherein the disinfecting cap cavity comprises a retention element extending from the cavity sidewall.

4. The disinfecting cap and syringe system of claim 1 , wherein the disinfecting cap cavity comprises an absorbent material.

5. The disinfecting cap and syringe system of claim 1 , wherein the disinfecting cap comprises a peelable lid that is sealed to the disinfecting cap exterior surface peripheral surface.

6. A disinfecting cap comprising:

an exterior surface comprising: an open end, a closed end, and a side surface extending between the open end and the closed end;

a cavity extending from the open end to receive an access site, the cavity comprising a bottom surface and sidewall;

a disinfecting solution at least partially filling the cavity; and

an aperture connected with the exterior surface, the aperture being sized to accept a thumb pad attached to a syringe plunger shaft, and the aperture comprising a slot that accommodates a rib of the syringe plunger shaft;

wherein the disinfecting cap is removeably attachable to a syringe by lateral movement of the aperture over the thumb pad.

7. The disinfecting cap of claim 6 , wherein the aperture further comprises an aperture bottom surface that at least partially encloses the thumb pad.

8. A disinfecting cap comprising:

an exterior surface comprising: an open end, a closed end, and a side surface extending between the open end and the closed end;

a cavity extending from the open end to receive an access site, the cavity comprising a bottom surface and sidewall;

a disinfecting solution at least partially filling the cavity; and

an aperture connected with the exterior surface, the aperture being sized to accept a thumb pad attached to a syringe plunger shaft, and the aperture comprising an aperture bottom surface that at least partially encloses the thumb pad;

wherein the disinfecting cap is removeably attachable to a syringe by lateral movement of the aperture over the thumb pad.

9. The disinfecting cap of claim 8 , wherein the aperture further comprises a slot that accommodates a rib of the syringe plunger shaft.

10. The disinfecting cap of claim 8 , wherein an end surface of the access site does not come in contact with the cavity bottom surface when the access site is inserted into the disinfecting cap.

11. The disinfecting cap of claim 8 , wherein the cavity further comprises threads formed on the sidewall.

12. The disinfecting cap of claim 8 , wherein the disinfecting solution comprises isopropyl alcohol.

13. The disinfecting cap of claim 8 , wherein the disinfecting solution comprises chlorhexidine gluconate.

14. The disinfecting cap of claim 8 , wherein the aperture is attached to the exterior surface closed end.

15. The disinfecting cap of claim 8 , wherein the aperture is attached to the exterior surface side surface.

16. The disinfecting cap of claim 8 , wherein the aperture is attached to the exterior surface such that the syringe plunger shaft extends in a direction opposite to the exterior surface open end.

17. The disinfecting cap of claim 8 , wherein the exterior surface side surface comprises a rectangular cuboid.

18. The disinfecting cap of claim 8 , wherein the exterior surface side surface comprises a cylinder.

19. The disinfecting cap of claim 8 , wherein the exterior surface open end further comprises a peripheral surface at least partially surrounding the cavity.

20. The disinfecting cap of claim 8 , wherein the thumb pad comprises a top surface and a bottom surface, and the aperture bottom surface encloses more than 50% of the thumb pad bottom surface.
