    摘要: An apparatus for extracorporeal blood treatment, comprising a treatment unit (2) having a first chamber (3) and a second chamber (4) separated from one another by a semipermeable membrane (5), a blood removal line (6) connected in inlet with the first chamber (3) and a blood return line (7) connected in outlet with the first chamber; an infusion line (9; 9a, 9b) of a replacement fluid and a fluid evacuation line (10) connected in outlet from the second chamber. A regulating device (20) of a transmembrane pressure is active on at least one of the lines and a control unit (15) is configured to: command the regulating device (20) by setting a first increase (δTMP1), determine a value of a control parameter (φ1) corresponding to the first increase, compare the value of the control parameter (φ1) with a reference value (φref) and, if the value of the control parameter is greater than the reference value, command the regulating device (20) by setting a second increase (δTMP2) which is greater than the first increase (δTMP1).

    摘要: The present invention relates to a method as well as a blood treatment unit for the implementation of this method for the best possible attainment of a predetermined substitution target during the ultrafiltration of blood. According to the invention, a method and a blood treatment unit for the implementation of the method is provided, wherein it is determined by detection of pressure measurement values in the blood treatment unit whether the calculated substitution target is achieved at the end of the dialysis session or not and in case of the result that the calculated substitution target cannot be achieved with the current dialysis parameters, an adjustment of the flow rate of blood, dialysate and/or substituate is performed in order to achieve the substitution target for a given treatment time in an optimal way or modify the treatment time for the given substitution target as little as possible.
