Preparation of medical solutions from powdery material

摘要

A package has a transport/storage state for storing powdery material which is to be mixed with a solvent to form a medical solution. The package includes a compartment which is at least partially defined by two opposing wall portions, and a connector. In the transport/storage state, the compartment contains the powdery material in the form of at least two distinct sets of powdery material of different compositions, where the opposing wall portions are brought into engagement with the powdery material so as to immobilize the sets of powdery material. When used for preparation of the medical solution, a fluid is selectively admitted into the package via the connector so as to expand the compartment and enable mixing of the sets of powdery material with the solvent in the compartment.

1. A package for storing powdery material which is to be mixed with a solvent to form a medical solution, said package comprising:
a compartment which is at least partially defined by two opposing wall portions and contains the powdery material in the form of at least two distinct sets of powdery material of different compositions, wherein the opposing wall portions are brought into engagement with the powdery material so as to immobilize the sets of powdery material, and the at least two distinct sets of powdery material are separated from each other by a constriction region, in which the wall portions are brought into close proximity with each other without being fixedly attached to each other; and a connector configured to selectively admit a fluid into the package, wherein the admitted fluid expands the compartment and mixes the sets of the powdery material with the solvent in the expanded compartment.
