PROBLEM TO BE SOLVED: To provide a blood purifying apparatus which suppresses a wrong 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 mounted, a blood pump 3, a dialyzer 2, and a venous pressure sensor 5 capable of detecting a pressure of blood of a patient which flows in the circuit 1b over time. The blood purifying apparatus includes a blood removal pressure sensor 15 capable of detecting a pressure of the blood of the patient which flows between an end of the circuit 1a and the blood pump 3 over time and alarm value updating means 16 which compares a time dependent change of the pressure detected by the venous pressure sensor 5 to a time dependent change of the pressure detected by the blood removal pressure sensor 15 and sequentially updates an alarm value of the other pressure based on the time dependent change of one pressure.
