摘要： An apparatus for extracorporeal treatment of blood (1) comprising a treatment unit, a blood withdrawal line, a blood return line, a preparation line and a spent dialysate line. A control unit (10) is configured to calculate values of a parameter relating to treatment effectiveness based on measures of the conductivity in the spent dialysate line. The value of the effectiveness parameter is calculated using one or more values representative of the conductivity in the spent dialysate line obtained relying on a mathematical model.

摘要： It is disclosed an apparatus for extracorporeal blood treatment (1) having a control unit (15) connected to an ultrafiltration device (20) and to a fluid preparation section (30) of fresh dialysis liquid. The control unit (15) is configured to receive measured values of the change of blood volume, the amount of ultrafiltration volume, and conductivity or to the concentration for at least one substance in the blood (BV %mes(t); UFmes(t), WLmes(t); Cbmes(t)); the control unit (15) is also configured to receive prescription values for the same parameters and to control ultrafiltration and adjust conductivity in the fresh dialysis liquid based on the difference between said measured values and said prescription values.

摘要： A control unit of an apparatus for extracorporeal blood treatment is configured to perform a control procedure comprising: calculating parameter control values to be set during a time interval after the instant in which the control is made, on the basis of actual values and of prescription values of variation in blood volume, ultrafiltration flow rate, concentration of sodium and/or potassium and heart rate or variation of heart rate of the patient; imposing the parameter control values during the time interval consecutive to the instant in which the control is made such that the actual values of the variation in blood volume track the prescription values of the variation in blood volume over a predetermined treatment time and the actual values of the heart rate or variation of heart rate track the prescription values of the heart rate or variation of heart rate over the predetermined treatment time.
