Abstract

A water-removal control system for a dialysis device includes a device for setting a planned volume of water to be removed; a device for setting a water-removing rate; and a time-display device for calculating from the planned volume of water to be removed and the water-removing rate the finishing time of the dialysis treatment. The control system allows the water-removing rate to be changed step by step by operating the rate-setting means during the dialysis treatment, and allows the time-display device to calculate the finishing time of the dialysis treatment synchronously with a stepped change in the water-removing rate, as well as to display the finishing time of the dialysis treatment.
