Plural component mixing system and method
First Claim
1. A plural component mixing system comprising:
- a rigid tubular housing containing a first component and having a vacuum movable piston and a sealed outlet;
a syringe with a rigid barrel containing a second component and having a manually retractable stopper capable of moving the housing'"'"'s piston upon retraction of the stopper, which syringe has a sealed outlet; and
coupling means for joining the outlets of the housing and syringe.

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.
