ABSTRACT:
A device for measuring the quantity of ultrafiltrate eliminated during a dialysis treatment. The device comprises two vessels of a known capacity wherein the ultrafiltrate coming from a pump is alternately received and then discharged by means of valves. The device further comprises two level measuring sensors which each emit a signal each time the ultrafiltrate attains a predetermined level in the corresponding vessel. Such sensors are connected to a processing and count control mechanism for analyzing the above-mentioned signals and for establishing the quantity of ultrafiltrate eliminated by the pump.
