A multichamber container and a method of preparing medical fluids having concentrates which make a contribution toward the electrical conductivity of the solution and are additionally prepared from concentrates which do not make a contribution toward the electrical conductivity of the solution. The multichamber container is configured by dividing solution components into multiple chambers, so that following the dissolving due to breaking open of the first chamber border of a solution component, which makes a contribution toward the electrical conductivity of the medicinal solution, another chamber border of another solution component which does not make any contribution toward the electrical conductivity of the solution is broken open.【課題】多チャンバ容器及び医療用流体調製方法を提供する。【解決手段】医療用流体は、溶液の導電性に寄与する濃縮物、及び溶液の導電性に全く寄与しない濃縮物を含む。本発明による多チャンバ容器は、溶液の成分が多くのチャンバに分割され、これらのチャンバは、医療用溶液の導電性に寄与する溶液成分の第1チャンバ境界を壊して開放した後、溶液の導電性に全く寄与しない別の溶液成分の別のチャンバ境界を壊して開放するように形成されている、ことを特徴とする。【選択図】図1
