    摘要: A pre-filled hypodermic syringe adapted for use with a retractable-type needle unit (18). The syringe has a barrel (10) provided with a piston member (14). The piston member (14) includes a plastics portion (30) mounting a dislodgeable blocking portion (36) of chemically inert material in such a way that the plastics portion (30) is not in contact with the pre-filled contents of the syringe.

    摘要: A syringe (1) comprises a barrel (2) having a needle (23) engaged in a glass hub (19). The glass hub (19) is retractable under the action of a spring (30) towards the trailing end of the syringe. The glass hub (19) is restrained against movement towards the trailing end by a crown (10) which is removably attached to the glass hub (19). A plunger (36) engages the crown (10), removing it from the glass hub (19) and allowing retraction of the needle (23). A core (45), removably attached to the end of the plunger by a resiliently deformable member, is then removed from the plunger, allowing the glass hub (19) and the needle (23) to be retracted into the plunger under the action of the spring (30).

    摘要: A syringe comprising a barrel (10), a plunger (11) and a needle unit (12). The needle unit (12) has a needle (30) which is biased inwardly of the barrel (10) but whose inward movement is blocked by a stop element (34). The needle (30) is released from the stop element (34) in response to the plunger (11) reaching the final part of, or the conclusion of, its delivery stroke to allow retraction of the needle (30). The barrel (10) of the syringe is provided with a seal (38) which contacts an outer peripheral surface of the stop element (34).
