[PROBLEMS] To provide a blood dialyzing apparatus capable of detecting removal of a puncture needle from a patient undergoing blood dialysis accurately by monitoring the potential difference at a predetermined portion while imparting a voltage to the blood flowing through a blood circuit, and capable of suppressing an increase of the manufacturing cost of a disposable blood circuit. [MEANS FOR SOLVING PROBLEMS] The blood dialyzing apparatus comprises an artery side blood circuit (1a) and a vein side blood circuit (1b), a blood pump (3), a dialyzer (2), a blood dialyzator body (6) having a dialysis liquid introduction line(L1) and a dialysis liquid discharge line (L2), a voltage imparting means (5), a potential detecting means (12), and a means (15) for monitoring removal of a puncture needle from a patient while referencing the potential detected by the detection means (12). The voltage imparting means (5) has one electrode (5a) interposed between an artery side puncture needle (a) in the artery side blood circuit (1a) and the blood pump (3), and the other electrode (5b) arranged in the dialysis liquid discharge line (L2). |
