PURPOSE: To minimize the consumptions of condensed dialysis solution, make-up water and energy and to reduce a cost of dialytic treatment without lowering the dialytic quality, by installing a control unit to feed the signals directed from the blood flow volume into the input side of the unit, from whose output side the signals as functions of blood flow volume are sent out into the system to adjust the flow of dialytic solution. CONSTITUTION: An automatically-operated type control circuit is included in the control unit 100. A signal led from a blood flow rate is sent into the input port of this control unit. The signal is, therefore, led from a feeding flow volume set for a blood pump 30, that is, led from a revolution velocity (RPM) of the blood pump 30, for instance. The flow volume of dialytic solution is automatically adjusted, based on the output signals of the control unit. For this purpose, the output of control circuit 100 is connected either to the dialytic solution pump 20 or more precisely, to the input of control circuit for adjusting the feeding flow volume of the pump. |
