SAFETY DEVICE WITH TRIGGER MECHANISM A medical safety device is provided and includes a needle hub having a needle supported thereon; and a safety shield (130) operatively mounted on the needle hub (120). 5 The safety shield (130) includes a pair of spaced legs (130a, 130b) and a foot member (138). Each proximal segment (134) includes a camming surface. The safety shield (130) further includes a trigger (13) supported on the foot member (136). The trigger (13) includes a camming member (184) and is movable to move the camming member (184) into engagement with the camming surfaces (1 60a, 162c) of the proximal segments (134) io to effect movement of the legs (130a, 130b) from a first position in which the distal ends (160a, 162a) of the distal segments shield a distal end of the needle to a second position in which the distal end of the needle (110) is at least partially exposed. The trigger (13) is removably secured to the foot member (136). Fx 28 24b ,7 13 22 17a 17b 2 24a 1823a 15 ' '16b 16 |
