ABSTRACT:
A device for treatment of blood by extracorporeal circulation comprises a dialysis liquid circuit having a supply tube (9a, 9b) on which is arranged a filter (21) having a first chamber and a second chamber (22, 23) which are separated by a filtering membrane (24), the supply tube having a first portion (9a) connecting a dialysis liquid source (10) to an inlet of the first chamber (22), and a second portion (9b) having an end connected to an outlet of the second chamber (23) of the filter (21) and another end which can be connected to an inlet of a compartment (3) of an exchanger (1) with semipermeable membrane (4). A feedback tube (25) connects the inlet of the first chamber (22) of the filter (21) to the outlet of the first chamber (22). A flushing pump (26) is arranged on the feedback tube (25) for circulating liquid in the first chamber (22) of the filter (21) and causing cleaning of the membrane (24) by tangential flushing.
