Method for efficient hemodiafiltration

摘要

An apparatus and method for hemodiafiltration are disclosed. The apparatus includes a first dialyzer cartridge containing a semi-permeable membrane that divides the dialyzer into a blood compartment and a dialysate compartment. Fluid discharged from the blood compartment of the first dialyzer cartridge is mixed with sterile substitution fluid to form a fluid mixture and the mixture enters a second dialyzer cartridge. The second dialyzer cartridge contains a second semi-permeable membrane which divides the second dialyzer cartridge into a blood compartment and a dialysate compartment. Hemodiafiltration occurs in both cartridges.
