Abstract

Abstract A guard for a hypodermic syringe needle which keeps the extremities and particularly the hands well away from the syringe to prevent accidental punctures with contaminated needles. The needle guard is in the form of a cylindrical cap which slides over the needle having a manipulating device to remove and replace the guard while keeping the hands well away from the needle. In one embodiment the manipulating device is in the form of a flexible handle having a resilient clamping flanges which clamp the device around the barrel of the syringe. The extension has a webbed hinge allowing it to easily flex outward away from the syringe needle for removal or replacement of the end cap. Alternately the end cap may be hingedly attached to a collar slideable on the syringe barrel by which the cap can be slid downward to remove the cap and retracted to replace the cap. The needle guard may also be in the form of a second cylinder forming a slideably mounted sleeve on the syringe barrel to cover the needle when extended or expose the needle when retracted.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 129 words
A hypodermic syringe needle guard comprising; a hollow tubular cap means having an open end and a closed end fitting over and shielding said needle; an elongated handle attached to said hollow tubular cap means proximate said open end, said elongate handle being constructed and arrange to extend a substantial distance away from said cap means so that said cap means can be removed and replaced while keeping hands away from said needle; hinge means hingedly attaching one end of said handle to said tubular cap means; securing means secruing the free end of said elongate handle remote from said hinge means to said syringe whereby said elongate handle may be secured out of the way on said syringe when said tubular cap is in place on said needle.
Claim 2
Dependent Claim 129 words
A hypodermic syringe needle guard comprising; a hollow tubular cap means having an open end and a closed end fitting over and shielding said needle; an elongated handle attached to said hollow tubular cap means proximate said open end, said elongate handle being constructed and arrange to extend a substantial distance away from said cap means so that said cap means can be removed and replaced while keeping hands away from said needle; hinge means hingedly attaching one end of said handle to said tubular cap means; securing means secruing the free end of said elongate handle remote from said hinge means to said syringe whereby said elongate handle may be secured out of the way on said syringe when said tubular cap is in place on said needle.
Claim 3
Dependent Claim 31 words
The needle guard according to claim 1 in which said securing means comprises a pair of clips on the free end of said elongate handle construction to snap on said syringe.
Claim 4
Dependent Claim 37 words
The needle guard according to claim 1 in which said securing mens comprises a collar attached to said free end of said handle constructed to slidably secure said free end of said elongate handle on said syringe.
Claim 5
Dependent Claim 46 words
The needle guard according to claim 3 including a hinge securing said collar to said free end of said elongate handle whereby said collar may be slid down on said syringe until said tubular cap clears said needle and can be swung away from said needle.
Claim 6
Dependent Claim 22 words
The needle according to claim 4 in which the first hinge is a self-hinge and said second hinge is a pinned hinge.
