Abstract
A needle safety system for a syringe having a generally cylindrical barrel extending along a longitudinal axis, the barrel having a hub from which a needle extends distally. The needle safety device has a sleeve at least partially enclosing the needle. A guide track is formed in the sleeve. A multi-part collar disposed in the sleeve has an inner collar which is fixedly connectable to the hub of a syringe barrel. An outer collar is rotatably attached to the inner collar. A guide pin extending radially outwardly from the outer collar slideably engages the guide track. A torqueable compression spring extending between the outer collar and the sleeve biases the sleeve in a distal direction and also biases the outer collar in rotation relative to the sleeve.
