PROBLEM TO BE SOLVED: To provide a dialysis fluid supply device capable of strictly controlling an amount of removed water in dialysis using a soft supply/discharge container while achieving reduction of cost without using a flow rate adjusting valve.SOLUTION: A dialysis fluid supply device 11 includes: a soft supply/discharge container 30 having a displaceable partition 40 that partitions the inside into a fluid supply chamber A and a fluid discharge chamber B; a fluid supply pump 51 for supplying a dialysis fluid to the fluid supply chamber A of the supply/discharge container 30; a circulation pump 80 for sending the dialysis fluid from the fluid supply chamber A to the fluid discharge chamber B; a water removing pump 90; a first relief valve 55 of the fluid supply pump 51; a second relief valve 81 of the circulation pump 80; and a control device 110 for adjusting the flow rate of the dialysis fluid that flows from the fluid supply chamber A to the fluid discharge chamber B by controlling a drive voltage of the circulation pump 80, and temporarily increasing the drive voltage of the circulation pump 80 so that, when the fluid discharge chamber B is filled with the dialysis fluid, the output pressure of the circulation pump 80 applied to the fluid discharge chamber B becomes a relief pressure. |
