Dialysis machine with control of hemolysis

A dialysis machine (1; 13) comprising a hemodialysis filter (2), an inlet branch (5) for carrying a dialysate to said filter (2), an outlet branch (6) to the dialysate exit said filter (2), an arterial line (3), which is responsible for transport of blood from a patient (P) to the filter (2), a venous line (4), which is responsible for transporting blood from the filter (2) the patient (P), and a plurality of pumps (3a, 9, 10, 16), which are suitable for circulating both blood and the dialysing solution, and a measuring device hemolysis (8; 8a; 8b) , said measuring device hemolysis (; 8a; 8 8b) being arranged to operate on a line (4; 3; 15) through which blood or a component thereof flowing in said output branch (6) the dialysing solution; said device being hemolysis meter (8; 8a; 8b) a device for measuring hemoglobin concentration and being an optical sensor; the dialysis machine further includes a drive command and control (11) connected to said measuring device hemolysis (8; 8a; 8b) to receive data from it hemolysis; characterized said dialysis machine that the control unit (11) is further connected to an intervention system and that the control unit (11) activates the intervention system once registered a value of abnormal hemolysis to indicate the value of abnormal hemoglobin and to change regimes pressure acting on the pumps (3a, 9, 10, 16).
