29. A method of reducing dialysate usage in renal dialysis, wherein said method defines one dialysis session, comprising:
-
circulating fluid in need of toxin removal from a renal dialysis patient through a first chamber of a dialysis cassette and back to said patient;
allowing toxins from said fluid in need of toxin removal to pass through a dialysis membrane from said first chamber into a second chamber of said dialysis cassette, wherein said second chamber contains dialysis fluid;
passing said dialysis fluid through a detoxification cartridge;
detoxifying said dialysis fluid; and
returning said fluid to said second chamber of said dialysis cassette. - View Dependent Claims (30, 31, 32)
