Abstract A needle guard for use with a syringe barrel including a mechanism for selectively enabling and not enabling passage of a needle through the end of the guard. Further, the guard includes an end closure for permanently closing a needle aperture therein and positively destroying the needle upon telescopically moving the guard and syringe barrel to a respectively retracted position.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
246 words
An assembly adapted for injecting or drawing fluid into or from a surface, said assembly comprising: a barrel portion for containing fluid, said barrel being equipped with a needle on an end thereof, said needle being adapted to pass fluid contained in said barrel into or from said substrate; tubular guard means telescopically related to and surrounding the end of said barrel equipped with said needle, said guard means having first and second ends and being adapted to telescope along said barrel between a first extended position, and a second retracted position; and end-piece means mounted on a first end of said guard means, said end-piece capable of being configured in first and second positions, said first position allowing passage of said needle through said first end of said guard when said guard is moved to said retracted position, said second position of said end-piece means blocking passage of said needle through said first end of said guard means, and enabling positive destruction of said needle when said guard is moved to said retracted position, wherein said end piece comprises a cap member which is hingedly attached adjacent to said first end of said guard means and hinges about an axis transverse to the direction of said needle, whereby said cap member can pivot between a position which blocks said needle from passing through said first end of said guard and a second position in which the cap member does not block passage of said needle.
Claim 2
Dependent Claim
246 words
An assembly adapted for injecting or drawing fluid into or from a surface, said assembly comprising: a barrel portion for containing fluid, said barrel being equipped with a needle on an end thereof, said needle being adapted to pass fluid contained in said barrel into or from said substrate; tubular guard means telescopically related to and surrounding the end of said barrel equipped with said needle, said guard means having first and second ends and being adapted to telescope along said barrel between a first extended position, and a second retracted position; and end-piece means mounted on a first end of said guard means, said end-piece capable of being configured in first and second positions, said first position allowing passage of said needle through said first end of said guard when said guard is moved to said retracted position, said second position of said end-piece means blocking passage of said needle through said first end of said guard means, and enabling positive destruction of said needle when said guard is moved to said retracted position, wherein said end piece comprises a cap member which is hingedly attached adjacent to said first end of said guard means and hinges about an axis transverse to the direction of said needle, whereby said cap member can pivot between a position which blocks said needle from passing through said first end of said guard and a second position in which the cap member does not block passage of said needle.
Claim 3
Dependent Claim
24 words
An assembly as in claim 1, wherein said end piece further comprises; locking means for locking said hingeable cap portion in said second position.
Claim 4
Dependent Claim
29 words
An assembly as in claim 1, further comprising: latching means for selectively locking said guard and said barrel portion in either of said first extended or second retracted positions.
Claim 5
Dependent Claim
198 words
An assembly adapted for injecting or drawing fluid into or from a surface, said assembly comprising: a barrel portion for containing fluid, said barrel being equipped with a needle on an end thereof, said needle being adapted to pass fluid contained in said barrel into or from said substrate; tubular guard means telescopically related to and surrounding the end of said barrel equipped with said needle, said guard means having first and second ends and being adapted to telescope along said barrel between a first extended position, and a second retracted position; and, cap means for closing off sand first end of said guard means, said cap means being pivotally mounted on said first end of said guard means so as to pivot about an axis transverse to the direction of said needle between first and second positions, said first position allowing passage of said needle through said first end of said guard when said guard is moved to said retracted position, said second position of said cap means blocking passage of said needle through said first end of said guard means, and enabling positive destruction of said needle when said guard is moved to said retracted position.
Claim 6
Dependent Claim
198 words
An assembly adapted for injecting or drawing fluid into or from a surface, said assembly comprising: a barrel portion for containing fluid, said barrel being equipped with a needle on an end thereof, said needle being adapted to pass fluid contained in said barrel into or from said substrate; tubular guard means telescopically related to and surrounding the end of said barrel equipped with said needle, said guard means having first and second ends and being adapted to telescope along said barrel between a first extended position, and a second retracted position; and, cap means for closing off sand first end of said guard means, said cap means being pivotally mounted on said first end of said guard means so as to pivot about an axis transverse to the direction of said needle between first and second positions, said first position allowing passage of said needle through said first end of said guard when said guard is moved to said retracted position, said second position of said cap means blocking passage of said needle through said first end of said guard means, and enabling positive destruction of said needle when said guard is moved to said retracted position.
Claim 7
Dependent Claim
