ABSTRACT:
A medical device including a syringe assembly and a shield system for delivering medicament to a patient. The syringe assembly includes a barrel defining a medicament reservoir, a needle cannula coupled to the barrel and in fluid communication with the reservoir, a plunger having a stopper positioned in the reservoir and a thumb pad for moving the plunger in the reservoir. The shield system has a first shield coupled to a forward end of the barrel, and a second shield movable from a first position disposed from the needle cannula tip to a second position covering the needle cannula tip. An urging member controlled by a retaining device urges the second shield to the second position upon movement of the stopper to a position which releases the retaining device.
