Novel enhanced device and technique for mixing and dispensing a preserved agent

摘要

A new and enhanced device and technique for mixing and dispensing a preserved agent is disclosed. The syringe-like device employs a novel piston fluid channel allowing for various chambers of the syringe to come into fluid communication when the piston is actuated. More especially, the person administering the preserved agent may visually confirm full resuspension and deliver an accurate dosage of the agent.
