Abstract:
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.

Claim (Index 19):
The apparatus of  claim 18 , wherein the parameter comprises the effective dialysance (D) and wherein each computed value (D k ) of said parameter at each respective variation is obtained using the formula\n D k =( Qd+WLR )\u00b7[1\u2212( Cd out2 \u2212Cd out1 )]/( Cd in2 \u2212Cd in1 ) wherein Cd out1  is the first outlet value taken by the characteristic in the spent dialysate line downstream of the secondary chamber in response to the change of characteristic (Cd in ) in the preparation line to said first inlet value Cd in1 , Cd out2  is the second value taken by the characteristic in the spent dialysate line downstream of the secondary chamber in response to the change of the characteristic (Cd in ) in the preparation line at said second inlet value (Cd in2 ), Cd in1 , Cd in2  are first and second inlet values taken by the characteristic (Cd) in the preparation line upstream of the secondary chamber, Qd is the fresh treatment liquid flow rate in the preparation line, and WLR is the weight loss rate of a patient under treatment; or the formula\n D K =( Qd+WLR )[1(2\u00d7 Cd out1 \u2212Cd out2 \u2212Cd out3 )/(2\u00d7 Cd in1 \u2212Cd in2 \u2212Cd in3 )] \n wherein \n Cd out1  is the first outlet value taken by the characteristic in the spent dialysate line downstream of the secondary chamber in response to the change of the characteristic (Cd in ) in the preparation line to said first inlet value (Cd in1 ), \n Cd out2  is the calculated second value which is representative of the value taken by the characteristic in the spent dialysate line downstream of the secondary chamber in response to the change of characteristic (Cd in ) in the preparation line from said first inlet value (Cd in1 ) to said second inlet value (Cd in2 ), \n Cd out3  is the calculated third value which is representative of the value taken by the characteristic in the spent dialysate line downstream of the secondary chamber in response to the change of characteristic (Cd in ) in the preparation line from said second inlet value (Cd in2 ) to said third inlet value (Cd in3 ), \n Cd in1 , Cd in2 , Cd in3  are first, second and third inlet values taken by the characteristic (Cd) in the preparation line upstream of the secondary chamber, \n Qd is the fresh treatment liquid flow rate in the preparation line, and \n WLR is the weight loss rate of a patient under treatment.
