An hemodiafiltration apparatus (1) presenting a filter (6); a first tube (3) for feeding blood from an artery (4) to the filter (6); a second tube (8) for feeding blood from the filter (6) to a vein (9) communicating with the artery (4) via a fistula (10); and a machine (13) for preparing the dialysis solution whereby toxic substances are removed from the blood in the filter (6); the apparatus (1) also presenting means (18) for varying the quantity of saline ions in the blood fed along the second tube (8); means (17) for detecting, before and after the variation, the quantity of saline ions in the blood fed along the first tube (3); and means (21) for processing the above findings, to define a parameter indicating the amount of purified blood recirculated from the vein (9), via the fistula (10), to the artery (4), and therefore indicating the effectiveness of the treatment. <MATH> |
