Abstract
Membranes and methods for making membranes are disclosed. The membranes include a polymeric matrix and a particulate material immobilized within the matrix. The membranes may find particular application in methods and apparatus for removing organic compounds from a biological fluid as part of a pathogen inactivation treatment.
Claims30
Apparatus for reducing the concentration of selected organic compounds within a biological fluid comprising:
- a biocompatible container;
- a composite membrane disposed within the interior of said container, said membrane comprising a selected quantity of a non-fiberized polymeric material blended with a selected quantity of a particulate sorbent material.
A method for reducing the concentration of selected organic compounds within a biological fluid comprising:
- providing a quantity of a biological fluid including selected organic compounds;
- and
- contacting said biological fluid with a composite membrane, said membrane comprising a selected quantity of a non-fiberized polymeric material blended with a selected quantity of activated charcoal particles substantially immobilized within said polymeric material.
A flexible composite membrane for reducing the concentration of selected organic compounds within a biological fluid, said membrane comprising:
- a selected quantity of a polymeric material and a selected quantity of activated charcoal particles substantially immobilized within said polymeric material;
- wherein said particles are non-uniformly dispersed throughout said polymeric material so as to provide a membrane with an inner portion and a selectively permeable outer skin.
