COMBINED SYRINGE AND NEEDLE SHIELD AND METHOD OF MANUFACTURE |
摘要 |
A safety syringe having a protective sleeve which is movable between a retracted position wherein the needle is exposed and a locked extended position wherein the needle is protected. A collar is attached to the distal end of the barrel to selectively engage a key on the shield in the retracted and extended positions. The locking mechanism preferably includes a series of ramps and slots which engage portions of the shield to retain the shield in the retracted and extended positions. The shield slides longitudinally between the retracted and extended positions and may be rotated about the barrel of the syringe to irreversibly lock the shield in the extended position.
