Patent ID: 10300191

Abstract:
A blood purification apparatus comprising: a blood circuit including an arterial blood circuit and a venous blood circuit and that is capable of extracorporeally circulating blood of a patient from a distal end of the arterial blood circuit to a distal end of the venous blood circuit; a blood purification device provided between the arterial and the venous blood circuit of the blood circuit and that is capable of purifying the blood flowing in the blood circuit; a dialysate introduction line for introducing dialysate into the blood purification device and a dialysate drain line for discharging drain liquid from the blood purification device; a liquid delivery pump provided to the dialysate introduction line and that is capable of causing the dialysate in the dialysate introduction line to flow; a heating device that is capable of heating the dialysate to be introduced from the dialysate introduction line into the blood purification device; a temperature-detecting device that is capable of detecting a temperature of the dialysate heated by the heating device; and a control device that is capable of controlling at least the liquid delivery pump and the heating device, wherein the control device is configured so that, if a dialysate temperature detected by the temperature-detecting device is higher than or equal to a predetermined value, the liquid delivery pump is controlled to cause the dialysate in the heating device to flow to an upstream side or a downstream side with respect to the heating device without allowing the dialysate to be introduced into the blood purification device.
