摘要：
When blood is purified by a blood purification membrane, an amount of albumin leakage from the blood is controlled, while the albumin leakage is inhibited. A blood purifying device 1 includes a control means that controls a transmembrane pressure difference across the blood purification membrane of a blood purifier. The control means obtains, on the basis of a function Fn given by a numerical expression: N(Tn) = Fn(P(Tn),Tn) (wherein n is an integer of not less than 1), where the numerical expression shows a relationship between a transmembrane pressure difference P(Tn) and a solute leakage concentration N(Tn) of a predetermined solute in the blood at each of one or more predetermined times Tn after initiation of blood purification, a transmembrane pressure difference Pa(Tn) corresponding to a target solute leakage concentration Na(Tn) at each of the one or more predetermined times Tn, and controls a transmembrane pressure difference during the blood purification on the basis of the transmembrane pressure difference Pa(Tn).
