US 2003/0150809 A1 · Systems and methods using multiple solvents for the removal of lipids from fluids

Abstract

This invention is directed to systems and methods for removing lipids from a fluid or from lipid-containing organisms from a fluid, such as plasma. These systems combine a fluid with at least one extraction solvent, which causes the lipids to separate from the fluid or from the lipid-containing organisms. The separated lipids are removed from the fluid. The at least one extraction solvent is removed from the fluid or at least reduced to a concentration enabling the fluid to be administered to a patient without undesirable consequences. Once the fluid has been processed, the fluid may be administered to a patient who donated the fluid or to a different patient for therapy.

Dependent claims

A device for removing at least one lipid from fluid containing lipids or lipid-containing organisms, comprising:

at least one hollow fiber contactor for contacting the fluid with a first extraction solvent, forming a first mixture comprising the fluid and the first extraction solvent, and dissolving at least a portion of the at least one lipid in the first extraction solvent;
a first solvent removal device for contacting the first mixture with a second extraction solvent, removing at least a portion of the first extraction solvent, and forming a second mixture comprising the first extraction solvent, the second extraction solvent and the fluid;
and
a second solvent removal device for removing at least a portion of the second extraction solvent from the second mixture.
