Abstract: A device and method for an extracorporeal blood treatment is described. The device comprising at least one exchanger equipped with at least one first inlet for the blood to be treated, a first fluid outlet and a second fluid outlet, an input line for blood to be treated connected to the first inlet of the exchanger, a blood output line (or venous line) connected to the first outlet of the exchanger, at least one treatment unit comprising at least one first fluid inlet and at least one first fluid outlet, the second outlet of the exchanger being in fluid communication with the first inlet of the treatment unit, where the first outlet from the treatment unit is in fluid communication with the input line and the second outlet of the treatment unit is in fluid communication with a first waste liquid discharge line.

Abstract: A device for the extracorporeal treatment of blood comprising at least one exchanger (1) comprising a semi-permeable membrane (6) dividing said exchanger into a first chamber (7) and a second chamber (8), at least one first inlet (2) for blood to be treated being in fluid communication with the first chamber (7) of the exchanger, a first fluid outlet (4) being in fluid communication with the first chamber (7) of the exchanger and a second fluid outlet (5) being in fluid communication with the second chamber (8) of the exchanger, an input line (10) for blood to be treated connected to the first inlet (2) of the exchanger (1), a blood output line (11) connected to the first outlet (4) of the exchanger (1), at least one treatment unit (21) comprising a semi-permeable membrane (26) dividing the treatment unit (21) into a first chamber (27) and a second chamber (28), at least one first fluid inlet (22) being in fluid communication with the second chamber (28) of the treatment unit (21) and at least one first fluid
