Blood ultrafiltration method for kidney dialysis - carries out separation and dialysis across membranes in separate zones simultaneously

摘要

The ultrafiltration method for blood is for use during a dialysis treatment session with an artificial kidney. The blood is passed into a separation zone with an ultrafiltration membrane, and into a separate exchange zone having a membrane allowing blood dialysis. Separation and dialysis take place in these zones simultaneously. The quantity of ultrafiltrate which it is desired to draw off from the patient is extracted from the separation zone.
