Abstract
A drug reconstitution and administration system includes a container for a concentrated drug or other medicament, a syringe assembly which can be pre-filled with a liquid diluent, and a mixing adapter assembly which facilitates mixing of the medicament with the liquid diluent. The adapter assembly includes inner and outer concentrically arranged, relatively movable sleeves, which together define an expandable mixing chamber within the adapter assembly. The container and pre-filled syringe are respectively fitted to the adapter assembly, with the contents of the container and the contents of the syringe transferred into the internal mixing chamber. A diluted drug mixture is formed in the mixing chamber, and the mixture is transferred into the syringe assembly for subsequent patient administration.
