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 for removing the cap. As an alternative the end of the needle guard can be flared to provide a flat surface for receiving an adhesive. The needle is then removed by pressing the adhesive base to any convenient surface. The needle guard is replaced by simply inserting the needle in the guard and snapping the guard from the surface by giving the syringe a quick twist when the cap is fully seated over the needle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
201 words
A hypodermic syringe needle guard comprising; shield means for shielding said needle; said shield means comprising; a hollow cylindrical cap having an open end and a closed end adapted to fit around said needle and be frictionally retained on a syringe; said closed end of said hollow cylindrical cap terminating in an end forming a base; adhering means bonded to said end forming a base of said hollow cylindrical cap; removing and replacing means on said hollow cylindrical cap for removing and replacing said hollow cylindrical cap; said shield including a hollow cylindrical sleeve slidably retained on said syringe, said sleeve when extended surrounding said needle with or without said hollow cylindrical cap; said hollow cylindrical sleeve having an aperture at its end remote from said syringe through which said hollow cylindrical cap may pass; and an adhesively retained membrane covering said aperture for sealing said aperture for sealing said hollow cylindrical sleeve around said cylindrical cap and needle until ready for use; whereby said membrane may be peeled off and said hollow cylindrical sleeve retracted to expose said cylindrical cap and needle for use and extended after use to cover said needle with or without replacement of said cylindrical cap.
Claim 2
Dependent Claim
201 words
A hypodermic syringe needle guard comprising; shield means for shielding said needle; said shield means comprising; a hollow cylindrical cap having an open end and a closed end adapted to fit around said needle and be frictionally retained on a syringe; said closed end of said hollow cylindrical cap terminating in an end forming a base; adhering means bonded to said end forming a base of said hollow cylindrical cap; removing and replacing means on said hollow cylindrical cap for removing and replacing said hollow cylindrical cap; said shield including a hollow cylindrical sleeve slidably retained on said syringe, said sleeve when extended surrounding said needle with or without said hollow cylindrical cap; said hollow cylindrical sleeve having an aperture at its end remote from said syringe through which said hollow cylindrical cap may pass; and an adhesively retained membrane covering said aperture for sealing said aperture for sealing said hollow cylindrical sleeve around said cylindrical cap and needle until ready for use; whereby said membrane may be peeled off and said hollow cylindrical sleeve retracted to expose said cylindrical cap and needle for use and extended after use to cover said needle with or without replacement of said cylindrical cap.

Claim 6
Dependent Claim
70 words
The needle guard according to claim 1 in which; said closed end of said hollowing cylindrical cap terminates in a flattened surface forming a base; said adhering means being bonded to said flattened end surface of said hollow cylindrical cap; whereby said hollow cylindrical cap may be removed from said syringe needle and attached to any convenient available surface for easy replacement while keeping the hands away from said needle.
Claim 7
Dependent Claim
142 words
A hypodermic syringe needle guard comprising; shield means for shielding said needle; said shield means comprising; a hollow cylindrical cap having an open end and a closed end adapted to fit around said needle and be frictionally retained on a syringe; said closed end of said hollow cylindrical cap terminating in an end forming a base; adhering means bonded to said end forming a base of said hollow cylindrical cap; removing and replacing means on said shield for removing and replacing said shield; a hollow cylindrical sleeve slidably retained on said syringe, said sleeve when extended surrounding said needle with or without said cylindrical cap; whereby said cylindrical sleeve may be retracted to expose said hollow cylindrical cap for removal from said syringe needle and attachment to any convenient available surface for easy replacement while keeping the hand away from said needle.
Claim 8
Dependent Claim
142 words
A hypodermic syringe needle guard comprising; shield means for shielding said needle; said shield means comprising; a hollow cylindrical cap having an open end and a closed end adapted to fit around said needle and be frictionally retained on a syringe; said closed end of said hollow cylindrical cap terminating in an end forming a base; adhering means bonded to said end forming a base of said hollow cylindrical cap; removing and replacing means on said shield for removing and replacing said shield; a hollow cylindrical sleeve slidably retained on said syringe, said sleeve when extended surrounding said needle with or without said cylindrical cap; whereby said cylindrical sleeve may be retracted to expose said hollow cylindrical cap for removal from said syringe needle and attachment to any convenient available surface for easy replacement while keeping the hand away from said needle.
