Manually driven needle shield assembly
First Claim
1. A shield assembly and syringe assembly comprising:
- a syringe assembly including a syringe barrel having opposed proximal and distal ends, a needle cannula projecting distally from said distal end of said syringe barrel; and
a shield assembly including a guide secured to a portion of said syringe assembly in proximity to said needle cannula, and a shield having a support wall and a pair of spaced apart side walls projecting from said support wall, said side walls being spaced from one another sufficiently for receiving said needle cannula therebetween, said shield being slidably engaged with said guide and being movable along a path having a generally acute angle with and toward said needle cannula, from a proximal position where said needle cannula is exposed to a distal position where said needle cannula is shielded between said side walls of said shield.

Abstract
A shield assembly and syringe assembly comprises a syringe assembly including a syringe barrel having a needle cannula projecting distally from its distal end and a shield assembly including a guide and a shield. The guide is secured to a portion of the syringe assembly in proximity to the needle cannula. The shield includes a support wall and a pair of spaced apart side walls projecting from the support wall. At least a portion of the side walls are spaced from one another sufficiently for receiving the needle cannula therebetween. The shield is slidably engaged with the guide and is movable along a path having a generally acute angle with and toward the needle cannula from a proximal position where the needle cannula is exposed to a distal position where the needle cannula is shielded between the side walls of the shield.

14. A shieldable hypodermic syringe assembly comprising:
-
a syringe barrel having opposed proximal and distal ends, a luer collar projecting distally from said distal end and having an internal thread; a needle assembly having a hub threadedly engaged with said luer collar such that a portion of said hub projects distally beyond said luer collar, said needle assembly further having a needle cannula with a proximal end securely engaged in said needle hub and a sharply pointed distal end; a guide connected to said portion of said hub projecting distally beyond said luer collar, said guide including at least one guide wall angularly aligned toward said needle cannula; and a shield having a support wall and a pair of side walls projecting from said support wall and being spaced from one another by a distance sufficient for receiving said needle cannula therebetween, said side walls being slidably engaged with said guide wall of said guide and being movable along a path having a generally acute angle with and toward said needle cannula from a proximal position where said shield is spaced proximally from said distal end of said needle cannula to a distal position where said needle cannula is protectively shielded between said support wall and said side walls of said shield. - View Dependent Claims (15, 16, 17)
