ABSTRACT:
A water-removal control system for dialysis device includes a volume-setting device for setting a planned volume of water to be removed; a rate-setting device for setting a water-removing rate; and a time-display for calculating from the planned volume of water to be removed, set by said volume-setting device, and the water-removing rate set by said rate-setting device, and for displaying the resultant finish time of dialysis treatment. The control system is so designed as to allow the water-removing rate to be changed step by step by operating the rate-setting device during dialysis, and allow the time-display to calculate the finish time of dialysis treatment synchronously with a stepped change of the water-removing rate as well as to display the resultant finish time of dialysis treatment.
