<p>Apparatuses and methods for hemodiafiltration are disclosed. Blood to be cleaned (27) enters a first dialyzer cartridge (23) containing a semi-permeable membrane (24) that divides the dialyzer (23) into a blood compartment (45) and a dialysate compartment (46). As blood (27) passes through blood compartment (45), plasma water containing blood substances is filtered across semi-permeable membrane (24) and additional blood substances are transferred across semi-permeable membrane (24) by diffusion. Partially dialyzed blood (18) exiting dialyzer cartridge (23) is mixed with sterile substitution fluid (16) to form a blood/substitution fluid mixture (17) and the mixture (17) enters a second dialyzer cartridge (22) containing a semi-permeable membrane (25) which divides the dialyzer cartridge (22) into a blood compartment (47) and a dialysate compartment (48). As mixture (17) passes through blood compartment (47), plasma water containing blood substances is filtered across semi-permeable membrane (25) and additional blood substances are transferred across semi-permeable membrane (25) by diffusion. Cleansed blood exits second dialyzer cartridge (22) and is recycled to the patient.</p> |
