摘要： A retractable syringe, plunger and releasable needle assembly including a retractable needle, a needle seal, a retaining member and an ejector member. The retaining member has a mating surface for mounting to a complementary mating surface of an interior wall of a syringe barrel. The plunger comprises a plunger outer, a plunger rod frangibly connected to a controlling member, a spring and a unitary plunger seal capable of engaging the retractable needle, wherein the plunger rod, plunger outer and the controlling member co-operate to releasably maintain the spring in an initially compressed state. After delivery of fluid contents of the syringe, the plunger forces the ejector member to release the retractable needle from the retaining member. Decompression of the spring at the end of depression of the plunger facilitates retraction of the retractable needle when engaged with the unitary plunger seal.

摘要： A retractable needle safety syringe (11) with plunger locking mechanism is disclosed. Locking means (36) are provided in the body (12) of the syringe to engage the plunger (13) once it is retracted after use, so that the syringe is rendered incapable of being used further. The locking means is preferably provided by a twist lock feature. A region of weakness (24) is also provided in the plunger so that after the needle is retracted into the body of the syringe, and the plunger engaged with the locking means, the plunger is broken off so it cannot be depressed again.

摘要： A syringe assembly having passive disabling structure includes a barrel and a plunger rod assembly. The plunger rod assembly includes a plunger rod and a stopper connected by an indexing locking element. The number of strokes of the syringe plunger before the stopper is locked into the barrel rendering the syringe assembly unusable is determined by the number of detents on the plunger rod and stopper which engage the locking mechanism. Upon completion of the final delivery stroke, any attempt to withdraw the plunger rod from the barrel will cause the locking element to engage the barrel and trap the stopper in the barrel preventing further use of the syringe.

摘要： This invention of a prepacked automatic retractable safety syringe comprises a needle hub with a needle tube and a rubber washer, a cap, a barrel, a spring, a vial, and a retractable plunger. To prevent or reduce injuries of needle stab and protect medical staffs, a forward action of the vial plus the needle hub compressed by the retractable plunger can drive a sliding movement between slides on the needle hub and snap hooks on the barrel via the spring's force to complete automatic retraction of the needle hub as well as the vial when an injection is finished.
