Abstract

A medical injection device (10) is provided which includes a shield system (14) and a syringe (12) which may be coupled to the shield system. The shield system includes a syringe holder (26), a shield (28) telescopically received in the holder and slidably coupled to the holder and an end fitting (32) which isolates the syringe flange from the holder, preventing damage to the flange. A spring (30) resiliently urges the shield from a retracted position to an extended position. Stop members are provided adjacent the distal end of the holder and the proximal end of the shield for maintaining the shield in the retracted position. Axial movement of the syringe with respect to the holder causes disengagement of the stop members, allowing the spring to move the shield to the extended position. Detents (52) are provided on the holder for maintaining the shield in the extended position.
