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.
Claims23
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.
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.
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.
