ABSTRACT:
A method of utilizing an apparatus of the type comprising a vial container hazardous material in the vial container in a condition requiring a diluent to be mixed therewith to form the liquid solution, and an assemblage carried by the vial container for providing (1) a sealed medicament chamber within the vial container within which the hazardous material is disposed, (2) a filter vented control chamber and (3) a sealed variable volume control chamber between the vented control chamber and the medicament chamber. The method is such as to enable an open end of a syringe needle of a diluent syringe having a syringe chamber containing diluent in communication therewith to be moved into and withdrawn successively from the chambers so as to mix the diluent with the hazardous material. The method also contemplates procedures for separately refilling a dosage syringe and for relieving any residual pressure in the vial chamber with the use of an empty syringe prior to initial or final refilling of a dosage syringe. The reconstituting, pressure relief and/or refilling procedures all being performed in such a way as to substantially prevent the hazardous material from entering the immediate atmospheric environment.
