Abstract

A needle covering system for a needle of a syringe. A boot of the system defines a contaminant-proof pocket for the needle. A sealing ring portion of the boot forms a seal with a support portion of the syringe. A body of the boot is collapsible to allow movement of a needle pierceable end portion of the boot toward the sealing ring portion for a tip of the needle to pass through the boot end portion for an injection. A securement collar of the system presses the sealing ring against the support portion of the syringe and is a remnant portion of a protective shell.

First claim

We claim:

1 . A needle covering system for a needle of a syringe, the needle covering system comprising:
a boot defining a contaminant-proof pocket for the needle, said boot including a sealing ring portion, a needle pierceable end portion at a base of said pocket, and a body extending between said sealing ring portion and said needle pierceable end portion and having an interior hollow for the needle, said sealing ring portion structured to form a continuous seal with a support portion of the syringe, said body collapsible to allow movement of said needle pierceable end portion toward said sealing ring portion for a tip of the needle to pass through said needle pierceable end portion; and a securement collar for pressing said sealing ring portion against the support portion of the syringe, said securement collar being a remnant portion of a protective shell, said remnant portion remaining after a disconnection of said remnant portion and a remainder portion of the protective shell during manufacture and the remainder portion is removed from a protective position around said boot body.

2 . The needle covering system of claim 1 wherein the connection between said remnant portion and said remainder portion of the protective shell is frangible, said frangible connection between said remnant portion and said remainder portion being broken during manufacture for the remainder portion to be removed.

3 . The needle covering system of claim 2 wherein said boot comprises a one-piece construction from a resilient material.

4 . The needle covering system of claim 2 wherein said securement collar comprises a ring shape.

5 . The needle covering system of claim 4 wherein said securement collar encircles an outer circumference of said sealing ring portion of said boot.

6 . The needle covering system of claim 5 wherein said securement collar comprises an outer radial periphery including plurality of tool engageable flats.

7 . The needle covering system of claim 2 wherein said boot comprises a lip encircling and projecting in an outer radial direction from said sealing ring portion, said lip forming with said sealing ring portion an annular hollow in which inserts said securement collar.

8 . The needle covering system of claim 2 wherein said boot body comprises first and second regions extending in an axial direction, said first region having a wall thickness that is thinner than a wall thickness of said second region to promote axial collapsing of said first region when said boot body collapses to allow movement of said needle pierceable end portion toward said sealing ring portion.

9 . The needle covering system of claim 8 wherein said boot first region is disposed between said sealing ring portion and said boot second region, and wherein said securement collar is axially located clear of said boot second region.

10 . The needle covering system of claim 9 wherein said securement collar is axially located clear of said boot first region.

11 . The needle covering system of claim 2 wherein the remainder portion of the protective shell includes an interior hollow that accommodates said boot.

12 . The needle covering system of claim 2 wherein said securement collar is mountable to the support portion by the sandwiching of the sealing ring portion therebetween.

13 . The needle covering system of claim 2 wherein said securement collar comprises means for mounting to the syringe, said mounting means being clear of said sealing ring portion.
