Abstract
A syringe assembly (10, 80, 132, 192) includes a syringe barrel (12, 86, 134, 194) having a proximal end and a distal end, a needle (18, 89, 140, 200) coupled to the distal end of the syringe barrel, a body (22, 142, 202) coupled to the syringe barrel, and movable shield (24, 82, 164, 222) for moving in an axial direction between a first position where the needle is exposed and a second position covering at least a portion of the needle. The body (22, 142, 202) is configured for enabling the shield (24, 82, 164, 222) to move to the second position and retain the shield in the second position. The shield (24, 82, 164, 222) can slide axially, and rotate relative to the body or slide transversely relative to the body when the shield is in the second position.
