PROBLEM TO BE SOLVED: To improve energy saving.SOLUTION: A dialysis drainage storage device includes: a first tank 160 for storing dialysis drainage 22 consisting of dialysis fluid used in a dialyzer a first drainage tube 161 connecting the dialyzer and the first tank 160, which serves as a flow channel for the dialysis drainage 22 a second tank 170 located inside the first tank 160, which is connected to the first drainage tube 161, and into which the dialysis drainage 22 discharged from the dialyzer flows a second drainage tube 162 connecting a drainage heat exchanger arranged outside the first tank 160 and the second tank 170, which serves as a flow channel for the dialysis drainage 22 a pump 180 connected to the second drainage tube 162 for sending the dialysis drainage 22 in the second tank 170 to the drainage heat exchanger and a third drainage tube 163 connecting the drainage heat exchanger and the first tank 160, which serves as a flow channel for the dialysis drainage 22. The dialysis drainage 22 flowing through the third drainage tube 163 is discharged outside the second tank 170 in the first tank 160.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2017,JPO&INPIT【課題】省エネルギー化の向上を図る。【解決手段】透析装置にて使用された透析液からなる透析排液22を貯える第1タンク160と、透析装置と第1タンク160とを接続し、透析排液22の流路となる第1排液管161と、第1タンク160の内部に位置し、第1排液管161と接続されて透析装置から排出された透析排液22が内部に流入する第2タンク170と、第1タンク160の外に配置された排液熱交換器と第2タンク170とを接続し、透析排液22の流路となる第2排液管162と、第2排液管162に接続され、第2タンク170内の透析排液22を排液熱交換器に送り出すポンプ180と、排液熱交換器と第1タンク160とを接続し、透析排液22の流路となる第3排液管163とを備える。第3排液管163を流れた透析排液22は、第1タンク160内において第2タンク170の外に排出される。【選択図】図2
