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 (QA) 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 (QOUT) 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.

An artificial kidney, comprising: an exchanger having first and second compartments separated by a semipermeable membrane, the first compartment being connected to a blood circuit for conveying a flow of blood outside a body of a patient, and the second compartment having an outlet for draining a waste liquid; a source of perfusion liquid for containing a substance (A) having a concentration [A]SOL; means for connecting the source of perfusion liquid to the patient; means for varying a flow rate of the perfusion liquid to the patient; and dosage means for adjusting a concentration of the substance (A) in the blood of the patient to a desired concentration [A]DES, the dosage means including means for calculating a flow rate (QA) of the perfusion liquid as a function of the clearance Cl of the artificial kidney for the substance (A), and means for controlling the flow varying means so that an actual flow rate of the perfusion liquid is substantially equal to the calculated flow rate (QA).
