摘要： A syringe structured to permit multiple filling and emptying cycles with a single syringe, but then to automatically disable that syringe to resist syringe reuse subsequent to a final dose-ejecting cycle. The syringe includes a plunger with a distal tip carrying capture structure that protrudes from the dispensing aperture of the syringe at a fluid fully-expelled position. A fluid discharge attachment can be coupled to the syringe to guide dispensing one or more dose of treatment substance. A first locking element, typically carried by the fluid discharge attachment, couples with the capture structure to resist retraction of the fully-depressed plunger, and thereby resists reciprocation of the plunger to prevent reuse of the syringe. Effectively, the discharge aperture of the syringe is pinned between an internally disposed stopper and the external capture structure. A stem of the plunger may optionally be structured to detach, leaving the stopper behind inside the syringe body, to further frustrate reuse of the syringe. Sometimes, a second locking element may be included to also resist unscrewing a fluid discharge device from a syringe.
