Abstract

A shielded needle assembly includes a needle guard slidably movable along a needle cannula from a proximal position where the distal end of the needle cannula (214) is exposed to a distal position where the distal end of the needle cannula is safely shielded within the needle guard (230). A hinged arm assembly connects the needle guard (230) assembly to needle hub. A trigger (250) 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.
