PROBLEM TO BE SOLVED: To provide a blood purifying apparatus which suppresses a false alarm and accurately detects abnormal situations such as an incorrect removal of a needle during a blood purifying treatment.
SOLUTION: The blood purifying apparatus includes a blood circuit 1 formed of an arterial-side blood circuit 1a and a venous-side blood circuit 1b where an arterial side puncture needle (a) and a venous-side puncture needle (b) are attached, a blood pump 3, a dialyzer 2, and a venous pressure sensor 5 capable of detecting a venous pressure of the circuit 1b over time. The blood purifying apparatus includes a blood removal pressure sensor 15 capable of detecting a blood removal pressure of the blood flowing between an end of the circuit 1a and the blood pump 3 over time and alarm value updating means 16 which sequentially updates an alarm value of the other pressure based on the amount of change per a prescribed time of one pressure by comparing the amount of change per a prescribed time in a time-dependent change of the pressure which is detected by the venous pressure sensor 5 to the amount of change per a prescribed time in a time-dependent change of the pressure which is detected by the blood removal pressure sensor 15.
