A blood purification device includes a blood circuit for extracorporeally circulating blood of a patient: a blood purifier provided on the blood circuit; a gas-liquid separator being provided on the blood circuit on the downstream side of the blood purifier on a blood flow and separating air bubbles contained in inflowing blood: and a liquid level adjustment unit capable of adjusting a liquid level height in the gas-liquid separator. The liquid level adjustment unit performs control so that the liquid level height during priming is higher than the liquid level height during treatment.

Blood purification device

A blood purification apparatus 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, with a blood purifier that is interposed between the arterial blood circuit and the venous blood circuit and purifies; a dialysate temporary chamber that temporarily stores dialysate received from a dialysate storage supported by a supporting unit; a substitution-fluid temporary chamber that temporarily stores substitution fluid received from a substitution-fluid storage supported by the supporting unit; a first dialysate introduction line through which the dialysate in the dialysate storage flows into the dialysate temporary chamber; and a substitution line through which the substitution fluid in the substitution-fluid storage flows into the substitution-fluid temporary chamber. The blood purification apparatus includes a dialysate transfer pump provided to the first dialysate introduction line and that transfers the dialysate in the dialysate storage to the dialysate temporary chamber, a substitution-fluid transfer pump provided to the substitution line and that transfers the substitution fluid in the substitution-fluid storage to the substitution-fluid temporary chamber, and a control unit that controls the dialysate transfer pump and the substitution-fluid transfer pump.
