Abstract

A device for automatically disinfecting a portion of a medical implement, such as a needless hub or injection port. The device includes a body shaped to engage the medical implement with the portion to be disinfected exposed. A disinfectant pad is mounted on the body to permit displacement of the pad relative to the body and is biased such that when the pad is displaced from a rest position, the pad is urged toward the portion to be disinfected to contact and disinfect it.

Claims

1. A device for automatically disinfecting a portion of a medical implement, comprising

a. a body shaped to engage the medical implement with the portion to be disinfected exposed,

b. a disinfectant pad connected to said body,

c. a mounting for said pad to permit displacement of said pad relative to said body, creating a gap between said pad and said portion to be disinfected, and

d. a resilient device biasing said pad such that when said pad is displaced from a rest position, where it is proximate the portion to be disinfected, said pad is urged to return toward the portion to be disinfected to contact and disinfect the portion.

2. The device according to claim 1, in which said medical implement comprises a needleless hub or injection port, and said body includes an aperture shaped to accommodate said hub or injection port.

3. The device according to claim 1, in which said mounting comprises a slide, said slide being movably secured to said body.

4. The device according to claim 1, in which said resilient device comprises at least one spring.

5. The device according to claim 1, in which said resilient device comprises an elastic band.

6. The device according to claim 1, in which said mounting comprises a cowl pivotally secured to said body.

7. The device according to claim 6, in which said resilient device comprises a torsion spring.

8. The device according to claim 1, in which said mounting includes a cover for said pad.

9. The device according to claim 1, in which said rest position is coincident with location of the portion to be disinfected.

10. A device for automatically disinfecting a needleless hub or injection port, comprising,

a. a body shaped to be mounted proximate an orifice of the needleless hub or injection port,

b. a disinfectant pad associated with said body,

c. a mounting for said pad to permit displacement of said pad relative to said body, creating a gap between said pad and said portion to be disinfected, and

d. means biasing said pad such that when said mounting is displaced from a rest position, said mounting is urged toward said orifice so that said pad contacts and disinfects said orifice.

11. The device according to claim 10, in which said body includes an aperture shaped to accommodate said orifice.

12. The device according to claim 10, in which said mounting comprises a slide, said slide being movably secured to said body.

13. The device according to claim 10, in which said biasing means comprises at least one spring.

14. The device according to claim 10, in which said biasing means comprises an elastic band.

15. The device according to claim 10, in which said mounting comprises a cowl pivotally secured to said body.

16. The device according to claim 10, in which said biasing means comprises a torsion spring.
