摘要
A blood purification apparatus is provided that includes a blood circuit including an arterial blood circuit and a venous blood circuit and that allows a patient's blood to extracorporeally circulate from a distal end of the arterial blood circuit to a distal end of the venous blood circuit; a blood purifier provided between the arterial blood circuit and the venous blood circuit and that purifies the blood flowing through the blood circuit, the blood purifier having a blood flow route through which the blood extracorporeally circulating through the blood circuit flows and a dialysate flow route through which dialysate flows, the blood flow route and the dialysate flow route being separated from each other by a blood purification membrane for purifying the blood; an ultrafiltration unit that performs ultrafiltration by filtering out water from the blood in the blood flow route through the blood purification membrane and draining the water through the dialysate flow route; and a substitution-fluid supply unit that supplies substitution fluid into the blood circuit. The blood purification apparatus includes a plasma-flow-rate-acquiring unit that acquires a plasma flow rate or a correlation value of plasma flow rate with reference to a blood concentration detected from the patient's blood and a plasma total protein detected from the blood flowing through the blood circuit.
