    • Fluid transfer apparatus particularly adapted for injecting a quantity of fluid from a fluid source into a stoppered vial containing material in lyophilized form. The apparatus comprises a cannula having a distal extremity for piercing the vial stopper and a handle mounted to the cannula to facilitate insertion and withdrawal of the cannula. An occlusion clamp is carried by the handle in position to control fluid flow through tubing extending from the cannula and through the handle for connection to the fluid source. The cannula and handle include interengageable elements movable relative to each other for rapid coupling and decoupling to enable demounting of the cannula and mounting of a replacement cannula. An indexing and stop system enables proper orientation of the cannula relative to the handle. The cannula replacement is conveniently sealed within a cap and wrench section to maintain sterility, the wrench section on separation from the cap being engagable with the replacement cannula to facilitate its rotation relative to the handle to mount the cannula to the handle.
    • 流体输送装置特别适用于将一定数量的流体从流体源注入含有冻干形式的含有材料的塞子小瓶中。 该装置包括具有用于刺穿小瓶塞子的远端的插管和安装到插管的手柄以便于套管的插入和抽出。 闭合夹具由把手承载在适当位置,以控制流体从通过插管延伸的管道流过并通过手柄连接到流体源。 套管和手柄包括可相对于彼此移动的可相互接合的元件,用于快速联接和去耦以使套管拆卸和更换插管的安装。 分度和停止系统使得套管相对于手柄的适当取向。 插管更换方便地密封在盖和扳手部分内以保持无菌性,与帽子分离的扳手部分与替换套管接合以便于其相对于手柄旋转以将插管安装到手柄上。
