Abstract
The ultrafiltration provided by an operating dialyzer is measured by sealing a portion of the dialysis solution flow path, including the dialysis unit, to prevent solution flow into or out of the portion, while effecting flow of the liquid to be dialyzed through a second flow path in the dialysis unit. Simultaneously, the dialysis solution flow path is in communication with a solution receptacle, at least part of which is vertically elevated over the dialysis unit. Accordingly, dialysis solution flows into the receptacle over a period of time under these conditions in a manner corresponding to the ultrafiltration of the dialysis system.
