Abstract
An installation having interchangeable functions for the replacement of the natural filtration of the blood. The installation has a reservoir of a sterile physiological solution. A three-way valve is provided in communication with an outlet of the reservoir. By selective adjustment of the three-way valve, the physiological solution from the reservoir may be selectively conveying to a first compartment of an exchanger for the spontaneous or assisted blood circulation and a second compartment for spontaneous or assisted circulation of a dialysis liquid and/or of an ultrafiltrate. A hydraulic resistor is provided for adjusting the circulation conditions of the physiological solution.
