Abstract
Methods and devices for powdered sorbent regeneration of biologic fluids are disclosed. The present invention includes three novel methods, which may be used singly or in any combination, for constraining or immobilizing powders so that they can be perfused with a biological fluid or dialysate: a porous carbon block filter, a filtration bed of very fine powder, and a cone-shaped reactor.
