ABSTRACT:
A shieldable needle assembly includes a needle guard slidably movable along a needle cannula from a proximal position where the distal end of the needle cannula is exposed to a distal position where the distal end of the needle cannula is safely shielded within the needle guard. A hinged arm assembly connects the needle guard assembly to needle hub. A trigger is articulated to the needle hub at a location proximally of the hinged arm. Distally directed digital forces cause the trigger to rotate such that the trigger urges the hinged arm from a collapsed condition to an extended condition.
