摘要：
An apparatus for extracorporeal blood treatment, comprising: at least one treatment unit (2) having at least a first chamber (3) and at least a second chamber (4) separated from each other by a semipermeable membrane (5)； at least one blood collection path (6) connected to an inlet opening of the first chamber and predisposed to draw blood from a patient, at least one blood return path (7) connected to an outlet opening of the first chamber and predisposed to return treated blood to the patient, forming the blood collection path (6), the blood return path (7) and the first chamber part of an extracorporeal blood circuit (8)； at least one infusion path (9； 9a, 9b) of a replacement fluid connected to the extracorporeal circuit or directly connectable with a patient and, optionally, a dialysis path connected at the entrance to the second chamber (4)； at least one fluid evacuation path (10) connected to an outlet port of the second chamber； sensor means for determining: - a first parameter related to a blood volume (BV%) of the patient； - at least a second parameter relative to a parameter selected from a group comprising: an ultrafiltration flow rate (UFR) through the membrane, a patient's weight loss rate (WLR), and a cumulative weight loss (WL )； - a third parameter (Cd, Na) relating to a conductivity of a liquid that crosses the dialysis route and / or the infusion route or a concentration of sodium or other predetermined substance of the liquid that crosses the dialysis route and / or the infusion path； and - a fourth parameter relative to a parameter selected from a group comprising: an infusion flow rate (QINF) of the replacement fluid that crosses the infusion path (9； 9a, 9b) or a transmembrane pressure (TMP) between the first camera and the second camera； a control unit (15) connected with the sensor means and configured to perform, in temporarily consecutive control moments (t), a control procedure comprising: - receiving, from the sensor means, measured valu
