Blood purification device
A blood purification device confirms whether a specific peak is provided by e.g. an ultrafiltration pump, to concentrate the blood or not and also accurately measures a blood re-circulation with a minimum of parameters providing a ratio of re-circulating blood. The blood purification device composed of arterial blood circuit route 1a and venous blood circuit route 1b, blood pump 3, dialyzer 2, water removal pump 8 providing the specific peak in the variation of blood concentration by removing water rapidly, and a detector detecting the specific peak, can measure the blood re-circulation thereby. The re-circulating blood flowing is the blood which was introduced again to arterial blood circuit route 1a after it had been returned to a patient from venous blood circuit route 1b. A first detector 5a installed in the arterial blood circuit route 1a and a second detector 5b installed in venous blood circuit route detector.
