    • An auto-disable syringe is disclosed which prevents re-use of the syringe whetver dose is delivered on the first use. A restrictor bobbin comprises two elements: a plunger lock 1 and a barrel lock 20 which are relatively freely movable for a limited distance. The barrel lock includes a barb 27 which engages with the barrel interior wall to prevent proximal movement of the barrel lock, whilst the plunger lock includes a barb 6 which engages with the plunger to prevent distal movement of the plunger withy respect to the barrel lock. The plunger lock includes a further barb 9 which is engageable with the plunger to prevent proximal movement of the plunger. A lock release 40 inlcudes a latch tine 53 which, in the syringe as shipped, prevents engagement of the barb 9 with the plunger. After withdrawal of fluid, e.g. a liquid medicament, initial distal movement of the plunger causes the latch 53 to disengage with the barb 9, thereby preventing any further proximal movement of the plunger.
    • 公开了一种自动禁用注射器,其防止在第一次使用时递送剂量的注射器的再次使用。 节流筒管包括两个元件:柱塞锁1和筒锁20,它们可以相对自由地移动一定距离。 枪管锁包括倒钩27,倒钩27与枪管内壁接合以防止枪管锁的近端运动,同时柱塞锁包括与柱塞接合的倒钩6,以防止柱塞相对于枪管锁的远端移动。 柱塞锁包括另一个倒钩9,其可与柱塞接合以防止柱塞的近端运动。 锁定释放件40包括锁定爪53,其在注射器中运送时防止倒钩9与柱塞接合。 在取出流体之后,例如 液体药物,柱塞的初始远端运动导致闩锁53与倒刺9脱离,从而防止柱塞进一步的近端运动。

    • A needle assembly includes a needle component (10) and a blunting component (26), the needle component (10) containing a needle cannula (12) mounted in a housing (16) which defines a fluid chamber such as a fluid chamber (20). The blunting component (26) contains a non-perforated, open-ended blunting probe (28) mounted in a shuttle (30). The needle cannula (12) and the blunting probe (28) are disposed telescopically one within the other without obstructing flow through the needle passageway, and are movable between a sharpened configuration and a blunted configuration. The blunting member (26) is configured to permit the open end of the blunting probe (28) to provide flow access to the fluid chamber (20) in the housing (16).
