In draining liquid in an AV-coupling-type blood circuit, it is determined that the blood circuit is in an AV-coupled state. A blood purification apparatus can switch between an open state in which fluid can flow through a blood removal side circuit and a blood return side circuit and a closed state in which the fluid cannot flow therethrough. The apparatus generates a difference in pressure between the blood removal side circuit and the blood return side circuit by rotating a blood pump in the case of the closed state. The apparatus then determines whether the blood circuit is the closed circuit by switching to the open state and monitoring the difference in pressure from detecting pressure inside the blood circuit. The apparatus drains liquid remaining in the blood circuit to a predetermined drainage destination with the blood circuit forming the closed circuit.
