Abstract

The installation is provided for dialysis and ultrafiltration. It allows periodic renewal of the dialysis liquid and precise control of the ultrafiltration. It comprises means allowing the dialysis liquid to be divided periodically and instantaneously into two parts, one (156) which remains in the dialyser while the other (152) is renewed. It furthermore comprises means (190, 222, 264) for imposing the desired volume of ultrafiltrate, which act on the speed of one (168) at least of two circulation pumps (166, 168) of the dialysis liquid surrounding the dialyser. The installation can be used in particular for artificial kidneys. <IMAGE>
