A hemodialysis device includes a hemodialysis device main body including an arterial blood circuit, venous blood circuit, blood pump, dialyzer, dialysate inlet and outlet lines, voltage adding device, electric potential measuring device, and monitoring device monitoring the needle when it is detached from the patient based on an electric potential measured by the electric potential measuring device. One electrode of the voltage adding device is attached between an arterial blood needle in the arterial blood circuit and the pump, and another electrode is attached to the dialysate outlet line. The hemodialysis device allows the precise detection of a needle that is detached from a patient taking a blood hemodialysis treatment by monitoring a voltage difference at a predetermined position while providing voltage to the blood flowing in the blood circuit. The device also allows the suppression of an increase in production cost for a disposable blood circuit. |
