ABSTRACT:
A system for storing a dry powdered drug component and a liquid in separate containers and mixing them immediately prior to injection. The system has a hypodermic syringe with an axially slidable stopper, and the syringe is coupled to a rigid tubular housing with a low friction vacuum movable piston. Simple reciprocation of the syringe stopper with an attached plunger having a laterally extending thumb pad or other graspable slip resistant surface automatically reciprocates the housing's low friction piston and causes quick and complete turbulent mixing. There is no need to turn the device over and over in the operator's hands to alternately squeeze or push opposite ends of the device.
