ABSTRACT:
The dialysis equipment has a dialysate path connectable to a dialysate source 1, and contains a feed pump 6, a dialyzer 10, and a controlled suction pump 13. During the operative phase, this dialysate path is traversed by the dialysate with a constant negative pressure being maintained in the dialysate chamber 101 of the dialyzer 10 relative to the blood chamber 102. In a subsequent measuring phase, the dialysate path is cut off from the dialysate source 1 and from a drain 15 via a valve device 2, 14. The same negative pressure is maintained in the dialysate chamber 101 as in the operative phase. The ultrafiltrate passing from the blood chamber 102 into the dialysate chamber 101 during the measuring phase causes the filling of a volume measuring device 5.
