    • Syringe assemblies having a passive disabling system to prevent reuse are provided. In one embodiment, the passive disabling system activates after completion of an injection cycle. An exemplary syringe assembly incorporates a stopper and plunger rod attached in a manner to prevent users from disassembling the syringe prior to completion of the injection cycle. The barrel may also include an annular extension or collar that extends from the proximal end of the barrel. In a specific configuration, the annular extension at least partially envelopes a portion of the thumb press to prevent the user from accessing the thumb press and moving the plunger rod in a proximal direction Syringe assemblies of one or more embodiments also include visual indicators or markers indicating whether a syringe assembly is used or the plunger rod is locked within the barrel.
    • 提供了具有防止重复使用的被动禁用系统的注射器组件。 在一个实施例中,被动禁用系统在注射循环完成之后激活。 示例性注射器组件包括以防止使用者在注射循环完成之前拆卸注射器的方式附接的塞子和柱塞杆。 枪管还可以包括从枪管的近端延伸的环形延伸部或套环。 在特定构造中,环形延伸部至少部分地包围拇指按压部分以防止使用者进入拇指按压器并沿近端方向移动柱塞杆。一个或多个实施例的注射器组件还包括指示 是否使用注射器组件或将柱塞杆锁定在镜筒内。
