Provided is a blood purification apparatus which can continue to accurately monitor a blood purification treatment state even if treatment conditions are changed during blood purification treatment. The blood purification apparatus can perform real-time monitoring on the blood purification treatment state, based on a concentration change in a discharge solution which is obtained by an arithmetic device. The blood purification apparatus includes a treatment condition change device that sets or changes treatment conditions as requested, and that causes a discharge solution concentration sensor to previously detect concentration of the discharge solution under the respective treatment conditions, and a storage device that stores the concentration of the discharge solution under the respective treatment conditions which is detected by the discharge solution concentration sensor in the treatment condition change device, as a first predetermined value corresponding to the respective treatment conditions. When the treatment conditions are changed during blood purification treatment, the arithmetic device obtains the concentration change in the discharge solution, based on the first predetermined value corresponding to the changed treatment conditions among the first predetermined values stored in the storage device. |

1. A blood purification apparatus comprising:
a blood circuit for extracorporeally circulating the blood of a patient; a blood purification device that is connected to the blood circuit, and that purifies the extracorporeally circulating blood; a dialysate introduction line for introducing a dialysate into the blood purification device; a dialysate discharge line for discharging a discharge solution generated due to the blood purification performed by the blood purification device, from the blood purification device; a concentration detection device that can detect a concentration of the discharge solution flowing in the dialysate discharge line; and an arithmetic device that can obtain a concentration change in the discharge solution, based on a first predetermined value detected by the concentration detection device and a second predetermined value detected after a predetermined period of time has elapsed therefrom, wherein the blood purification apparatus can perform real-time monitoring on a blood purification treatment state, based on a concentration change in the discharge solution which is obtained by the arithmetic device, and the blood purification apparatus further comprises: a treatment condition change device that sets or changes treatment conditions as requested, and that causes the concentration detection device to previously detect the concentration of the discharge solution under the respective treatment conditions; and a storage device that stores the concentration of the discharge solution under the respective treatment conditions which is detected by the concentration detection device in the treatment condition change device, as the first predetermined value corresponding to the respective treatment conditions, and wherein when the treatment conditions are changed during blood purification treatment, the arithmetic device obtains the concentration change in the discharge solution, based on the first predetermined value corresponding to the changed treatment conditions among the first predetermined values stored in the storage device. |
