Abstract
A medical safety device is provided and includes a needle hub having a needle supported thereon; and a safety shield operatively mounted on the needle hub. The safety shield includes a pair of spaced legs and a foot member. Each proximal segment includes a camming surface. The safety shield further includes a trigger supported on the foot member. The trigger includes a camming member and is movable to move the camming member into engagement with the camming surfaces of the proximal segments to effect movement of the legs from a first position in which the distal ends of the distal segments shield a distal end of the needle to a second position in which the distal end of the needle is at least partially exposed. The trigger is removably secured to the foot member.
