Abstract
A blood purification apparatus that includes a blood circuit including an arterial blood circuit and a venous blood circuit and through which blood of a patient is allowed to extracorporeally circulate; a blood purification unit connected to and provided between the arterial blood circuit and the venous blood circuit and that purifies the blood flowing through the blood circuit; a blood pump provided to the arterial blood circuit and that delivers the blood of the patient from a distal end of the arterial blood circuit to a distal end of the venous blood circuit; a substitution line through which a substitution fluid is allowed to be introduced into the blood circuit; and an infusion portion attached to the substitution line and from which a predetermined liquid drug to be administered to the patient is allowed to be infused into the substitution line. The blood purification apparatus includes a control unit that executes a drug introduction mode in which the substitution fluid in the substitution line is introduced into the blood circuit, the control unit causing the liquid drug infused from the infusion portion in the drug introduction mode to be introduced into the blood circuit together with the substitution fluid; and a calculation unit that calculates a volume of the substitution fluid introduced from the substitution line into the blood circuit with the execution of the drug introduction mode.
