PROBLEM TO BE SOLVED: To enable a dialysis fluid of a low oxidation-reduction potential to be manufactured.SOLUTION: A hydrogen gas is dissolved in a dialysis fluid or a solution of a dialysis fluid original agent, and a reduction dialysis fluid or a reduction dialysis fluid stock solution of which the oxidation-reduction potential is made lower is prepared by an apparatus. A dialysis fluid/stock solution hydrogen-reduction apparatus 1 includes a deaerating unit, a second film module 40, and a pressurizing tank 70. In this case, the deaerating unit is a unit which deaerates the gas in a dialysis fluid or a solution of a dialysis fluid original agent, and includes at least a first film module 30. The second film module 40 is connected with the side for transporting the dialysis fluid or the solution of the dialysis fluid original agent from the deaerating unit, and can mix the hydrogen gas which is present across a film with the dialysis fluid or the solution of the dialysis fluid original agent through pores 102 which are formed in the film. The pressurizing tank 70 is connected with the downstream side of the second film module 40, and pressurizes the dialysis fluid or the solution of the dialysis fluid original agent in order to increase the solution concentration of the hydrogen gas contained in the dialysis fluid or the solution of the dialysis fluid original agent.COPYRIGHT: (C)2013,JPO&INPIT【課題】酸化還元電位の低い透析液を製造する【解決手段】本発明は、透析液あるいは透析液原剤の溶液中に水素ガスを溶解させ、酸化還元電位をより低くした還元透析液あるいは還元透析液原液を製造する装置であって、透析液あるいは透析液原剤の溶液中の気体を脱気するユニットであって少なくとも第一膜モジュール30を含む脱気ユニットと、脱気ユニットから透析液あるいは透析液原剤の溶液を輸送する側に接続され、膜を隔てて存在する水素ガスを当該膜に形成される孔102を通して透析液あるいは透析液原剤の溶液中に混合可能な第二膜モジュール40と、第二膜モジュール40の下流側に接続され、透析液あるいは透析液原剤の溶液を加圧してそれに含まれる水素ガスの溶解濃度を高めるための加圧タンク70と、を備える透析液・原液水素還元装置1に関する。【選択図】図1
