A device for the preparation of sterile pharmaceutical solutions for intravenous use includes a first bag (1), a second bag (8), and a filtration unit (5). The filtration unit (5) has an inlet tube and an outlet tube, the inlet tube of the filtration unit (5) being attached to an outlet port in the first bag (1) and the outlet tube being connected to an inlet port through which aqueous solvent may be introduced. The first bag (1) has a flexible lining that defines a chamber and a plurality of individual storage containers (3) attached to the lining of the chamber. The containers (3) have tops that may be snapped off by manipulation of the lining opposite the chamber. The removal of the container allows ingredients contained within to be individually released into the chamber on demand. The combination of the ingredients and the aqueous solvent forms a pharmaceutical solution of known composition. The first bag (1) may be placed within an enclosure into which air is pumped to exert a positive pressure upon the first bag (1 ) to force the pharmaceutical solution through the filtration unit (5) and into the second bag (8). The second bag (8) may also have individual storage containers (9) that contain sterile medicinal preparations that may be released into the pharmaceutical solution. |
