Abstract
An apparatus for controlling the ultra-filtration in connection with a hemodialysis treatment comprises a plurality of storage containers for the dialysis liquid. These containers are connected in parallel to each other and to the circulatory system of the dialysis liquid by groups of valves which are controlled by an automatic timer mechanism in such a manner that these containers are operatively connected to the circulatory system in a timed sequence. The groups of valves are operatively connected to the inlet and outlet ports of these containers. In addition to the main pump for circulating the dialysis liquid, there is a branching pump for withdrawing a dialysis liquid proportion from the system and a pump for filling the containers with a fresh dialysis liquid.
