ABSTRACT:
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.
