ABSTRACT:
A safety shield is provided for a medical implement having a needle cannula. The safety shield includes a guard that is slidably movable along the needle cannula from a proximal position where the tip of the needle cannula is exposed to a distal position where the tip of the needle cannula is safety shielded. A hinged arm connects the guard to a hub of the needle cannula or to the medical implement with which the needle cannula is used. The hinged arm can be collapsed upon itself, such that the guard is adjacent the hub of the needle cannula. Alternatively, the hinged arm can be extended to cause the guard to move distally along the needle cannula and into a position for shielding the tip of the needle cannula. A spring may be provided to assist movement of the guard toward the distal shielded position.
