ABSTRACT:
The artificial kidney includes an exchanger having two compartments separated by a semipermeable membrane, the first compartment of which is connected to a circuit for conveying a flow of blood outside the body. A source of treatment liquid is provided, and a control unit selectively connects the source to either the inlet of the second compartment of the exchanger or to the blood circuit as a function of the transmembrane pressure. This kidney provides optimum purification treatment for patients suffering from temporary kidney failure.
