摘要：
A blood treatment device having a blood purification element (1), which is divided into two chambers by one by a semipermeable membrane (3), whose first chamber (4) is part of a dialysis fluid circuit ( 20) and whose second chamber (2) is part of an extracorporeal blood circuit (10), having a dialysis fluid inlet line (22), which part of a dialysis fluid processing unit (21) to supply dialysis fluid new to the first chamber (4) and / or directly in the blood circuit (10), having a dialysis fluid outlet line (23) to remove used dialysis fluid from the first chamber (4), having a blood inlet line (11) to supply blood to the second chamber (2), having a blood return line (12) to return blood from the second chamber (2), having a control unit (34) for control the blood treatment device, having a unit analysis unit (32) that is connected to the control unit (34), having at least one sensor (31), which is connected to the analysis unit (32) in at least one blood circuit (10) or dialysis fluid (20) to detect the concentration of a substance, which is capable of penetrating through the semipermeable membrane (3), whereby the analysis unit (32) is suitable for determining based on the measured values of the at least one sensor (31) the Cbi concentration of this substance in the blood in the blood entry line (11), the instantaneous transfer rate ΔM / Δt of this substance through the membrane (3) and the total amount M of this substance withdrawn through the membrane (3) during the treatment, so that a first permissible range of values for the Cbi concentration of the substance, a second permissible range of values for the transfer rate ΔM / Δt and a third permissible range of values for the total amount M of The substance to be removed is stored in the analysis unit (32), and therefore the analysis unit (32) is designed so as to instruct the control unit (34) on the extent to which the treatment device for blood performs the blood treatment respecting the three ranges of admi
