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.
Claims98
A regeneration system for a biologic fluid in extracorporeal blood treatment comprising:
- a housing comprising an interior volume and at least one inlet and at least one outlet;
- a solid filtration module comprising a surface adsorptive agent positioned within the housing between the inlet and the interior volume;
- a bed of sorbent particles positioned within the housing between the filtration block and the outlet;
- and
- a cone shaped reactor placed below the solid filtration module to create a fluidized bed within it, keeping most of the larger sorbent particles within the reactor and allowing the fine particles to flow with perfusing solution to form the above bed of particles.
