摘要：
An apparatus for the treatment of extracorporeal blood comprising: - a filtration unit (2) having a primary chamber (3) and a secondary chamber (4) separated by a semi-permeable membrane (5)； - a blood withdrawal line (6) connected to an inlet of the primary chamber (3), - a blood return line (7) connected to an outlet of the primary chamber (3), said blood lines being configured for its connection to a cardiovascular system of the patient； - a dialysis supply line (8) connected to an inlet of the secondary chamber (4)； - a dialysis effluent line (13) connected to an outlet of the secondary chamber (4)； - a preparation device (9) for preparing a dialysis fluid connected to said dialysis supply line (8) and comprising regulating means (10) to regulate the composition of the dialysis fluid, - a sensor (11) for measure a dialysate parameter value in the dialysis effluent line (13), said dialysate parameter being at least one selected from the group consisting of dialysate conductivity, a parameter related to dialysate conductivity, concentration of at least one substance in the dialysate and a parameter related to the concentration of at least one substance in the dialysate； - a control unit (12) connected to the sensor (11) to receive said dialysate parameter value, said control unit (12) being also connected to the regulation means (10) and programmed to calculate a representative value of the plasma conductivity, wherein said control unit (12) is configured to: - set a parameter value for the dialysis fluid in the dialysis supply line (8) to an initial reference value, said parameter being the dialysis fluid at least one selected from the group consisting of conductivity of the dialysis fluid, a parameter related to the conductivity of the dialysis fluid, concentration of at least one substance in the dialysis fluid and a parameter related to the concentration of at least a substance in the dialysis fluid； - after setting the parameter value of the dialysis fluid to
