PURPOSE:To dispense with a roller tube pump, in supplying a diluted dialytic solution to a dialyser by an aspirator, by controlling the stock solution of the dialytic solution to the aspirator by detecting the concn. of said diluted solution. CONSTITUTION:A nagative pressure pump 3 is operated and water heated to a predetermined temp. by a heater is flowed to a dialytic solution circuit supply line 7 while the flow amount thereof is made constant by a regulation valve 8. A stock solution 11 of a dyalytic solution is supplied to the supply line 7 from the suction port of an aspirator 12 through a flexible tube 10 by said water jet stream and the diluted dialytic solution is supplied to a dialyser 1. At this time, the concn. of the diluted dialytic solution is measured by the concn. sensor 13 of a dialytic solution concn. control means 14 and the measured value is subjected to control operation processing by a control part 15 and the movable part 18 of a throttle mechanism 19 is moved to an A- or B-direction by a drive part 16 to regulated the flow amount of the stock solution 11 of the dialytic solution flowing through the flexible tube 10 while making the concn. of the diluted dialytic solution constant.
