Abstract
A system for retaining a tip protector on a needle having a curved portion or bend adjacent the tip. A Braun clip tip protector is used in combination with a small sleeve which fits around the needle such that it is free to slide towards the needle tip until stopped by the bend. In that stopped position, the tip protector covers the tip but cannot slide off the end of the needle.
Claims21
A device for protecting a sharp tip of a medical needle having a bend in its shaft, comprising:
- a needle tip protector including a protective portion configured to cover the needle tip to prevent a person from being stuck by the tip, and including a slide portion configured to slide along said shaft to a protective position in which the protective portion covers the needle tip and the slide portion is stopped by said bend to prevent the protective portion from moving beyond the protective position, and wherein the bend defines a first needle axis upstream of the bend and a second different needle axis downstream of the bend.
A device comprising:
- a needle having a shaft with a bend adjacent a sharp tip;
- a tip protector slidably mounted on said shaft;
- a sleeve comprising a length sized such that it may slide freely over said shaft, but may not slide around said bend, the length of said sleeve being selected to stop said sleeve at a location which prohibits said tip protector from sliding off said needle and which allows said tip protector to cover said sharp tip;
- and
- wherein the bend defines a first needle axis upstream of the bend and a second different needle axis downstream of the bend.
A method of preventing needle stick for a needle having a bend in its shaft adjacent a sharp tip of the needle, comprising the steps of:
- positioning on the needle a tip protector having a protective portion configured to cover the tip and a slide portion configured to move on the needle towards the tip until it is stopped by the bend;
- interengaging the protective portion with the slide portion so that the protective portion covers the tip when the movement of the slide portion towards the tip is stopped by the bend;
- and
- wherein the bend defines a first needle axis upstream of the bend and a second different needle axis downstream of the bend.
A needle tip protector device comprising a spring clip having an opening and a sleeve coaxially disposed over a needle having a shaft and a bend in the shaft, wherein the sleeve comprises a length and a cross-sectional dimension that are sized to be stopped by the bend, and wherein the bend defined two different needle axes.
