Abstract
An improved hemodialysis ultrafiltration system. Dialysate input and output pumps are linked to maintain their volume flows substantially equal. A pressure attenuator and a pressure amplifier on the dialyzer dialysate inlet and outlet, respectively, are employed to control dialyzer pressure on the dialysate side. Dialysate output in excess of dialysate input is separated through the action of the dialysate output pump for measurement. The ultrafiltration rate may be controlled through the pressure transformers and the instantaneous ultrafiltration rate and total ultrafiltration volume may be continuously monitored.
