Claim 0:
1. 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 the arterial blood circuit through the blood purification unit to 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, wherein the infusion portion is made of rubber and the infusion portion is configured to allow the predetermined liquid drug to be infused by medical workers;
the blood purification apparatus comprising:
a display;
a control unit that executes a drug introduction mode, when a starting portion of the display is actuated, in which the substitution fluid in the substitution line is introduced into the blood circuit, the control unit causing the predetermined liquid drug infused from the infusion portion in the drug introduction mode to be introduced into the blood circuit together with the substitution fluid, wherein the control unit upon execution of the drug introduction mode, a volume of the substitution fluid introduced to the blood circuits is displayed on the display as a substitution-volume of a substitution-volume display portion of the display;
a calculation unit that calculates:
the volume of the substitution fluid introduced from the substitution line into the blood circuit with the execution of the drug introduction mode; and
a target ultrafiltration volume for water removal from the blood of the patient that flows through the blood purification unit with an ultrafiltration pump, is settable, and the control unit corrects the target ultrafiltration volume an addition of the volume of water that corresponds to the volume of the substitution fluid calculated by the calculation unit to the target ultrafiltration volume, and removes water from the patient's blood through the blood purification unit by activating the ultrafiltration pump based on the target ultrafiltration volume after correction;

wherein the display provides an indication that prompts the medical workers to execute the drug introduction mode.
