PROBLEM TO BE SOLVED: To provide a dialysis system capable of using dialysis fluid that suits individually different disease states of dialysis patients.SOLUTION: A dialysis system 1 includes stock solution generation devices 20-22 for generating each stock solution of dialysis fluid containing a plurality of stock solutions, a plurality of personal dialysis devices 11, stock solution supply lines 40-42 for supplying the stock solution from the stock solution generation devices 20-22 to each of the personal dialysis devices 11, a dialysis water supply line 13 for supplying dialysis water to each of the personal dialysis devices 11, and a dialysis fluid generation device 90 for generating dialysis fluid by mixing the plurality of stock solutions supplied from the stock solution supply lines 40-42 with the dialysis water supplied from the dialysis water supply line 13 in each of the personal dialysis devices 11. The dialysis fluid generation device 90 is configured so as to change the mixing ratio of the plurality of stock solutions and the dialysis water, and change the concentration of the dialysis fluid.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】個々に異なる透析患者の病態に合った透析液を用いることができる透析システムを実現する。【解決手段】透析システム1は、複数の原液を含む透析液のそれぞれの原液を生成する各原液生成装置20~22と、複数の個人用透析装置11と、各原液生成装置20~22から各個人用透析装置11に原液を供給する各原液供給ライン40~42と、透析用水を各個人用透析装置11に供給する透析用水供給ライン13と、各個人用透析装置11において、各原液供給ライン40~42から供給された複数の原液と透析用水供給ライン13から供給された透析用水を混合して透析液を生成する透析液生成装置90と、を有している。透析液生成装置90は、複数の原液及び透析用水の混合比を変更して透析液の濃度を変更可能に構成されている。【選択図】図1
