The unit includes a dialyzer (3) in which a membrane (4) defines two channels, one for extracorporeal blood and the other for a dialysis fluid; a first conduit (5) along which the dialysis fluid is fed by first pumping means (6, 11, 14) to the dialyzer; a second conduit (17) along which the fluid from the dialyzer flows into a vessel (18); a third conduit (25) hydraulically connecting a first point (5c) of the first conduit, upstream from the dialyzer, to a second point (17a) of the second conduit, downstream from the dialyzer; intercepting means (26, 27, 28) installed along the third conduit, along the first conduit downstream from the first point (5c), and along the second conduit upstream from the second point (17a); an assembly (41, 51)) installed along the second conduit, between two points (17b, 17c) downstream from the second point (17a), and which permits free flow at one stage, and by means of second pumping means (31, 51)) at a different stage; and means (23, 24) fitted to the vessel, and for determining the flow rate of the fluid fed from the second conduit into the vessel. <IMAGE> |
