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 1):
An apparatus for extracorporeal blood treatment comprising:\n a blood treatment unit having a primary chamber and a secondary chamber separated by a semi-permeable membrane; a preparation line in fluid communication with an inlet of the secondary chamber of the blood treatment unit and configured to convey fresh treatment liquid to the secondary chamber, the fresh treatment liquid presenting a characteristic (Cd in ) which is one selected from the group of:\n conductivity in the fresh treatment liquid, and \n concentration of at least one substance in the fresh treatment liquid; \n a spent dialysate line in fluid communication with an outlet of said secondary chamber and configured to remove spent liquid from the secondary chamber, the spent liquid presenting a characteristic (Cd out ) which is one selected from the group of:\n conductivity in the spent liquid, and \n concentration of at least one substance in the spent liquid; and \n a control unit configured to command execution of a task for determination of a parameter indicative of the effectiveness of the extracorporeal blood treatment, said task comprising:\n receiving at least one prescription baseline (Cd set ) for the characteristic (Cd in ) in the fresh treatment liquid; \n causing fresh treatment liquid to flow in the preparation line to the secondary chamber with the characteristic being at said prescription baseline (Cd set ); \n causing spent liquid to flow out of the secondary chamber into the spent dialysate line; \n causing an upstream variation of the characteristic (Cd in ) in the fresh treatment liquid with respect to said prescription baseline (Cd set ) thereby causing a corresponding and timely delayed downstream variation of the same characteristic (Cd out ) in the spent liquid flowing in the spent dialysate line; \n measuring a plurality of values taken by a reference portion of said downstream variation of the characteristic (Cd out ) in the spent liquid, said reference portion having duration shorter than the entire duration of the downstream variation; \n determining a downstream curve (Cd out(t) ) representative of the values taken by the characteristic (Cd out ) in the spent liquid for the entire duration of the downstream variation; \n computing one or more significant value of said downstream variation of the characteristic (Cd out ), said one or more significant value of the downstream variation relating to a time subsequent to the duration of the reference portion; and \n computing at least one value of a parameter indicative of the effectiveness of the extracorporeal blood treatment by using said one or more significant value of said downstream variation of the characteristic (Cd out ) in the spent liquid.
