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.

Blood purification apparatus

The blood purification system includes a plurality of monitoring devices () with a dialyzer () to perform a blood purification treatment on a patient. A dialysate supplying device () supplies a dialysate to each of the monitoring devices (). The plurality of monitoring devices () and the dialysate supplying device () are connected to each other by a LAN cable &#x3b1;. Predetermined information can be transmitted from the dialysate supplying device () to a specified monitoring device (), out of the plurality of monitoring devices (). The specified monitoring device () can perform an individual operation.

A dialysate supplying device () supplies a dialysate to each of the monitoring devices (). The plurality of monitoring devices () and the dialysate supplying device () are connected to each other by a LAN cable &#x3b1;. Thus, predetermined individual information relating to the plurality of monitoring devices () is transmitted from each of the monitoring devices () to the dialysate supplying device ().

A mixing apparatus which can reliably prevent an auxiliary liquid from being unintentionally mixed into a main unit even when a failure occurs in a switching device, and which can prevent the switching device or an auxiliary flow route from being damaged even when a pressurizing device malfunctions due to the failure. The mixing apparatus includes a pipe circulating dilution water; a pipe circulating a disinfecting solution; a pressurizing pump circulating the disinfecting solution in the pipe toward the pipe; and a check valve capable of optionally turning on and off the pipe. The mixing apparatus further includes a discharge flow route which consists of a flow route branched from between the check valve and the pressurizing pump in the pipe, and which can discharge the dilution water or the disinfecting solution; and an electromagnetic valve which can control the flow route between the check valve and the pressurizing pump in the pipe to have a pressure lower than that of the pipe when not mixing the disinfecting solution with the dilution water.
