Abstract:
1. An apparatus for extracorporeal blood treatment comprising: at least a treatment unit having at least a first chamber and at least a second chamber separated from one another by a semipermeable membrane; at least a blood removal line connected to an inlet port of the first chamber and predisposed to remove blood from a patient, at least a blood return line connected to an outlet port of the first chamber and predisposed to return treated blood to the patient, the blood removal line, the blood return line and the first chamber being part of an extracorporeal blood circuit; at least an infusion line of a replacement fluid connected to the extracorporeal circuit or directly connectable to the patient; a dialysis line connected to an inlet port to the second chamber; at least a fluid evacuation line connected to an outlet port of the second chamber; a first sensor configured to obtain data regarding a first parameter relating to a blood volume (BV %) of the patient; a second sensor configured to obtain data regarding a second parameter relating to at least one of: an ultrafiltration flow rate (UFR) through the semipermeable membrane, a weight loss rate (WLR) of the patient, and an accumulated weight loss (WL) of the patient; a third sensor configured to obtain data regarding a third parameter relating to at least one of: a conductivity of a liquid in the dialysis line or the infusion line (Cd), or a concentration in a predetermined substance of the liquid in the dialysis line or in the infusion line (Na); a fourth sensor configured to obtain data of a fourth parameter relating to at least one of: an infusion flow rate (Q a control unit in communication with the sensors and programmed to perform a control procedure comprising:
