ABSTRACT:
An improved syringe incorporating a solid powdered medicament and a dissolving fluid in a compact manner utilizes a compartment for the solid material which may be readily packaged commercially and an arrangement whereby fluid and solid components may be mixed and the latter dissolved while maintaining complete hermetically sealed conditions for all components including the injection needle until the latter is ready for injecting into the patient or intravenous device. This is accomplished by a specially constructed tube which surrounds and seals the syringe barrel, injection needle, and medicament and diluent until ready for use. Added features are rigidity, simplicity and economy in manufacture, safety against malfunction and simplicity in operation by customarily trained personnel.
