Patent ID: 7955308

Claim:
A passive needle guard comprising a body having open proximal and distal ends and a cavity therein for receiving a barrel of a syringe through an open proximal end; one or more elongate fingers disposed near the distal end of the body each having an end tab; a shield having proximal and distal ends and comprising latch members extending from the proximal end of the shield, the shield being slidably attached to the body and slidable between a retracted position for exposing a needle extending from the distal end of the body and an extended position for substantially covering the needle, the shield being biased to slide towards the extended position when the latch members are contacted by a radial element of a plunger of the syringe; one or more slots disposed in a proximal region of the shield each configured to engage an end tab when the shield is in the extended position to prevent retraction of the shield.
