  • Artificial kidney with device for filtering dialysis liquid
    Patent number: 5431811
    Abstract: A filtration device includes an ultrafilter having an inlet chamber, an outlet chamber, and an ultrafiltration membrane separating the inlet chamber from the outlet chamber. An inlet line flow connects the inlet chamber to a source of dialysis liquid. Pressure sensors determine pressure values on opposite sides of the membrane, and a controller calculates a transmembrane pressure therefrom and compares the calculated transmembrane pressure with a predetermined threshold value. If the threshold value is reached, the controller emits a threshold signal to either warn an operator or alternatively to automatically divert flow to bypass the ultrafilter.
