Abstract
A medical device includes a syringe assembly and a shield system for delivering medicament to a patient. The syringe assembly includes a barrel defining a medicament reservoir, and a needle cannula coupled to the barrel and in fluid communication with the reservoir. The shield system has a hub coupled to the syringe barrel, a shield movably arranged on the hub, the shield being movable from a first position disposed from the needle cannula tip to a second position during insertion of the needle into a patient and movable from the second position to a third position covering the needle cannula tip after the needle cannula is removed from the patient. An urging member urges the shield to the third position upon removal of the needle cannula from the patient. A cover sleeve connected to the needle barrel surrounds the hub and the urging member.
