<p>Haemodialfiltration apparatus comprising a haemofilter (11) with a membrane, a first circuit for a dialysis solution with a syringe-type liquid pump (20) and valves located upstream (19, 21) and downstream (18) from the haemofilter (11) and a second circuit for blood with a blood pump (15) and valves located upstream (14, 16) and downstream (17) from the haemofilter (11). Haemodialfiltration method comprising in each cycle reversing the filtration direction in the membrane of the haemofilter (11) by means of the coordinated operation of the pumps (15, 20) and the valves (14,16- 19,21) controlled by a control unit, in such a way that after filtering and washing of a predetermined volume of blood plasma, an equivalent volume of replacement fluid is filtered towards the blood flow and within the haemofilter (11) for the blood to recover its original haemocrit and to minimize coagulation risks.</p> |
