PROBLEM TO BE SOLVED: To inexpensively secure the feed of RO (Reverse Osmosis) water of a large flow rate without being affected by fluctuation of feed of the RO water, to mix an undiluted solution A and an undiluted solution B in a constant ratio into the RO water of a prescribed quantity, and to produce a dialysis fluid of a stable concentration easily and in large quantities.SOLUTION: A dialysis fluid feeding device 1 comprises: a feed water tank 10 arranged in a prescribed level; and a mixer 40 arranged downward than the feed water tank 10 to mix an undiluted solution A and an undiluted solution B into water supplied by a level difference pressure. The mixer 40 is constructed to mix the undiluted solution B into water supplied from the feed water tank 10, and to mix the undiluted solution A into the water at the downstream side than the mixing point of the undiluted solution B. |
