<p>Apparatus for and method of automatically controlling the quantity and rate of liquid removed from blood during hemodialysis. The apparatus supplies dialysate in a single pass system in a closed, controlled volume circuit which includes an above atmospheric pressure portion and a below atmospheric pressure portion. The above atmospheric pressure portion includes a pair of chambers for alternate supply to and removal of the dialysate from the below atmospheric pressure portion which contains an artificial kidney and a third means for removing fresh dialysate from the above atmospheric pressure portion; the below atmospheric pressure portion includes means which isolates the kidney containing portion and restores pressure to spent dialysate to a pressure at least equal to or higher than the pressure of the dialysate fed into said closed circuit; the above atmospheric circuit also includes means for removing gas from the spent dialysate prior to filling the spent dialysate removal chamber before discard.</p> |
