Abstract

Systems and methods are disclosed for identifying and deploying a protective cover about a percutaneous puncture site formed by a hypodermic needle. In the preferred embodiment, a marking agent or puncture site covering, the latter of which preferably takes the form of a bandage, is releasably secured upon either the needle hub of the hypodermic needle or on a sliding member or sleeve axially moveable along the length of said needle that forms a marking or detaches therefrom once compressed about the puncture site.

Claims

1. A system for indicating the puncture site made by a hypodermic needle having a proximal end and a sharpened distal end and a needle hub formed at the proximal end thereof comprising:

a. a sliding member axially mounted upon said needle and operative to move along the length thereof; and

b. a marking agent formed upon said sliding member and operative to impart indicia about said puncture site formed by said distal end of said needle.

2. The system of claim 1 wherein said marking agent is selected from the group consisting of an ink, dye and an adhesively-attachable marker.

3. The system of claim 1 wherein said sliding member is operative to remain in fixed position and form a housing about said sharpened distal end of said needle once said marking agent is deployed at said puncture site.

4. The system of claim 3 wherein said system further comprises a change in profile formed along said needle for engaging with said sliding member, said engagement fixing said sliding member into position relative said distal end of said needle.

5. The system of claim 1 wherein said sliding member comprises a sleeve.

14. The system of claim 1 wherein said system further includes a tether securing said sliding member to said hub of said hypodermic needle.

22. The system of claim 1 further comprising a resilient member operative to urge the sliding member to the distal end of the needle.

23. The system of claim 22 wherein said resilient member is a spring.

6. A system for covering the puncture site made by a hypodermic needle having a proximal end and a sharpened distal end and a needle hub formed at the proximal end thereof comprising:

a. a sliding member axially mounted upon said needle and operative to move along the length thereof;

b. a protective covering detachably mounted upon said sliding member and operative to cover said puncture site formed by said distal end of said needle when compressed against said puncture site, said detachable protective covering operative to remain at said puncture site upon removal of the system; and

c. a resilient member operative to urge said sliding member to the distal end of the needle.

7. The system of claim 6 wherein said sliding member is operative to remain in fixed position and form a housing about said sharpened distal end of said needle once said covering is deployed at said puncture site.

8. The system of claim 7 wherein said system further comprises a change in profile formed along said needle for engaging with said sliding member, said engagement fixing said sliding member into position relative said distal end of said needle.

9. The system of claim 6 wherein said sliding member comprises a sleeve.

10. The system of claim 6 wherein said protective covering comprises an absorbent material coupled to an adhesive for securing said covering about said puncture site.

11. The system of claim 10 wherein said covering comprises a bandage.

12. The system of claim 6 wherein said covering is provided with a medication to be administered about said puncture site.

13. The system of claim 12 wherein said medication is selected from the group consisting of a topically applied antibiotic, anti-inflammatory agent and anesthetic agent.

15. The system of claim 6 wherein said system further includes a tether securing said sliding member to said hub of said hypodermic needle.

21. The system of claim 6 wherein said resilient member is a spring.

16. A method of deploying an object about a puncture site formed by a hypodermic needle having a proximal end and a sharpened distal end and a needle hub formed at the proximal end thereof with a sliding member axially mounted upon said needle and operative to move along the length thereof, said method comprising the steps:

a. releasably attaching said object to said sliding member;

b. injecting said hypodermic needle to form said puncture site, said needle being injected to a depth sufficient to cause said object detachably mounted upon said sliding member to abut the skin about said puncture site;

c. releasing said object about said puncture while said object abuts said puncture site in step “

b”

; and

d. withdrawing said hypodermic needle such that said object remains about said puncture site formed thereby, while said sliding member advances along said hypodermic needle to the distal end.

17. The method of claim 16 wherein said object comprises a marking agent.

18. The method of claim 16 wherein said marking agent is selected from the group consisting of a dye, an ink or an adhesively-attachable marker.

19. The method of claim 16 wherein said object comprises a protective covering.

20. The method of claim 19 wherein said covering comprises a bandage.
