ABSTRACT:
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.
