Title:
ULTRAFILTRATION SPEED CONTROLLER OF BLOOD EXTERNAL RECIRCULATION PURIFYING APPARATUS
Document Type and Number:
Japanese Patent JPS6041972
Kind Code:
A
Abstract:
An apparatus for controlling the ultrafiltration rate in machines for the extracorporeal purification of blood in which the difference obtained in the blood circuit by an electromagnetic flow meter is used for controlling the ultrafiltration rate. The ultrafiltration rate is controlled by controlling the transmembrane pressure across the membrane separating the blood chamber from the dialysis fluid chamber in a dialyzer. In one embodiment, the pressure in the blood circuit is varied to change the transmembrane pressure. In a second embodiment, the pressure in the dialysis solution circuit is varied.
