SOLUTION: A dialyzate circuit 4 comprises: a first dialyzate chamber 11 having a supply chamber 11a and a collection chamber 11b; and a second dialyzate chamber 12 having a supply chamber 12a and a collection chamber 12b. Control means 5 opens and closes an opening/closing valve on a required position in the dialyzate circuit 4, for alternately switching operations of both chambers 11, 12, for supplying the dialyzate to a dialyzer 2, and collecting used dialyzate. Pressure which is detected by a pressure detector 23 is always input to the control means 5. The control means 5 detects an operation abnormality in dialysis treatment based on pressure fluctuation input from the pressure detector 23, when operations are switched between the first dialyzate chamber 11 and second dialyzate chamber 12, and outputs an alert signal.EFFECT: The operation abnormality in dialysis treatment can be surely detected.SELECTED DRAWING: Figure 4 |
