Abstract

A method and apparatus for autologous plasma delipidation of animals (including humans). The method comprises drawing blood from the animal, separating the plasma from the red blood cells, delipidating the plasma with a lipid solvent, remixing the delipidated with the red blood cells and re-introducing the delipidated blood into the animal. A preferred apparatus which utilizes the above method comprises a needle for drawing blood from the animal and the blood is then fed into a centrifugal separator where the blood is separated into the plasma and red blood cells. The plasma is then mixed with a biphase solvent and passed through a separator where the delipidated plasma (in an aqueous phase) is drawn off from the lipid components (in an organic phase). After removal of solvent, the delipidated plasma is remixed with the red blood cells and re-introduced to the animal by a re-infusion needle.
