    摘要： An artificial kidney dosing method includes the steps of connecting a patient to an exchanger having first and second compartments separated by a semipermeable membrane. The first compartment is connected to a circuit for extracorporeal blood circulation, and the second compartment has an outlet for draining a waste liquid. After the patient is connected to the exchanger, a perfusion liquid containing a substance (A) is perfused to the patient. The concentration of substance (A) in the blood of the patient is adjusted to a desired concentration {A}.sub.DES, by controlling a flow rate (Q.sub.A) of the perfusion liquid as a function of (1) a flow rate (Q.sub.OUT) of the waste liquid; (2) the desired concentration {A}.sub.DES ; and (3) a concentration {A}.sub.SOL of substance (A) in the perfusion liquid, whereby during this adjustment, a transfer of substance {A} through the semipermeable membrane is taken into account.

    摘要： An artificial kidney comprises an exchanger (1) having two compartments (2, 3) separated by a semipermeable membrane (4), a first compartment (2) being connected to a circuit (5, 7) for extracorporeal blood circulation, the second compartment (3) having an outlet for draining waste liquid. Means (22, 25) are provided for controlling the flow rate (Q.sub.A) of a sterile solution containing a substance (A) to be perfused into the circuit (5, 7) for conveying a flow of blood outside the body, which flow rate is controlled as a function of the flow rate (Q.sub.OUT) of waste liquid. This kidney makes it possible to dose a substance such as a medicine, glucose or bicarbonate, accurately into the blood of a patient undergoing treatment by hemofiltration, hemodialysis, or hemodiafiltration.
