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.一種注射器,建立用以允許利用一單一注射器進行多次填充及清空循環,但隨後在一最終排放循環之後係自動地使注射器失效以抗拒注射器之再利用。注射器包括具有一遠極頂端之一柱塞,遠極頂端帶有擷取結構,此擷取結構係於一流體完全排出位置凸出於配送口。一流體排放輔具係可耦接至注射器以導引配送一或多劑之治療物質。典型地由流體排放輔具所帶動之一第一鎖固元件係耦接擷取結構,藉以抗拒完全受壓柱塞之收縮,並且藉此抗拒柱塞往復運動以防止注射器之再利用。實際上,注射器本體之排放口係被牽制於一內置止擋器與一外擷取結構之間。柱塞之一桿係可選擇性地建立用以進行分離而使得止擋器留在注射器本體內,進而使得注射器無效再利用。有時可包括一第二鎖固元件,亦可利用第二鎖固元件以抗拒一流體排放裝置自一注射器而鬆開。100‧‧‧組合102‧‧‧注射器本體104‧‧‧近極端106‧‧‧遠極端108‧‧‧公魯厄鎖定錐形元件110‧‧‧具螺紋母承座120‧‧‧柱塞組合122‧‧‧柱塞桿124‧‧‧蕊元件126‧‧‧擦拭元件140‧‧‧第一鎖固元件142‧‧‧可工作輔具144‧‧‧流體噴霧器151‧‧‧遠端介面186‧‧‧遠端凸出腳188‧‧‧上升區域190‧‧‧遠極端192‧‧‧受壓承載區域
