Abstract
There is provided an improved system for controlling ultrafiltration in hemodialysis which is independent of the membrane used in the dialyzer. A load cell measures the instantaneous amounts of fluid in a reservoir which receives fluids from the dialyzer and feeds this information into an electronic controller which has been programmed for the desired ultrafiltration. The controller generates an error signal and controls a negative pressure control valve which, in turn, determines the rate and thus amount of ultrafiltration.
