Abstract
A dialysis apparatus has a connection channel that communicatively connects a dialysate circuit and a blood circuit, and circulates dialysate from the dialysate circuit to the blood circuit via the connection channel during a priming operation. A blood pump has a tube attachment device that switches from an unattached state in which a tube is positioned outside a housing and permits liquid to circulate thereinside, to an attached state in which the tube is in the housing and a rotor compresses the tube. At the time of priming, the liquid feeding pump feeds dialysate from the dialysate circuit to the blood circuit via the connection channel. With the blood pump being in the unattached state, the dialysate is circulated past the blood pump, and then, with the blood pump in the attached state, the dialysate is circulated in a direction opposite to the blood pump.
