A filtering device comprising an inlet (8) and an outlet (9) for the liquid filtered and an outlet (11) for the filtrate and with the filtration being arranged so that it takes place in two chambers (2,3) connected in series, which consist at least partly of membrane material through which the filtration is taking place. The device is intended primarily to be used in connection with medical treatment of blood and here in particular in connection with haemofiltration or plasmafers, in which methods a thickening of the blood and consequently a pressure drop occurs. The characteristic feature of the invention is an inlet (19) for replacement liquid, which is adapted so as to introduce this liquid between the said two chambers (2,3). |
