Abstract
A safety needle assembly has a needle hub and a needle cannula projecting from the hub. Wings project transversely from the hub to facilitate manipulation and positioning of the needle assembly. A shield is hingedly attached to the needle hub and can be rotated from a first position where the needle cannula is exposed to a second position where the needle cannula is shielded. At least one latch may be disposed on the shield for secure locked engagement with the hub, the wings and/or the tubing extending from the hub. A spring may also be provided for propelling the shield into the second position.
Claims4
A safety needle assembly comprising:
- a needle hub having opposed proximal and distal ends;
- a needle cannula projecting distally from said distal end of said needle hub;
- a safety shield hingedly connected to said needle hub by a first hinged connection for hinged movement form a first position where said needle cannula is exposed to a second position where said needle cannula is shielded;
- and
- an actuator having opposed proximal and distal ends, wherein said proximal end of said actuator is rotatably connected to said hub by a second hinged connection at a location proximal to said first hinged connection of said shield to said hub,
- wherein said distal end of said actuator is slidably attached to said safety shield, so as to slide in relation to said safety shield,
- wherein actuation of said actuator causes said safety shield to pivot and rotate along an arcuate path about said needle hub into said second position.
