ーム。 In the blood side circuit of a positive pressure hemodialysis circuit, an arterial side pressure detector is provided between the blood side circuit of the dialyzer and the blood pump, and a circuit constrictor that automatically adjusts the arterial pressure of the circuit downstream of the dialyzer. In addition, the pressure signal from the arterial side pressure detector is input to a central control device that controls opening and closing of the circuit constrictor, and the ultrafiltration pressure of the dialyzer is controlled by the central control device during dialysis. When the circuit constrictor is pinched or enlarged to change the adjustment, or when the rotational speed of the blood pump is adjusted to accelerate or decelerate to change the blood flow rate of the dialysis circuit, the circuit constriction occurs in conjunction with the operation. The central controller calculates the rate of change and direction of the output value of the arterial pressure detector when the device is caused to expand, and if the rate of change in the output is less than a predetermined rate of change or a change in the opposite direction is detected. A blood circuit abnormality control alarm characterized by having a structure that, when detected, issues an alarm warning that a part of the circuit is clogged.
