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.
Claims17
A regeneration system for partial dialysate regeneration of dialysate in an extracorporeal blood treatment comprising:
- a housing comprising an interior volume and at least one inlet and at least one outlet;
- a carbon block positioned within the housing between the at least one inlet and the interior volume:
- a replaceable dialysate bag for removal of small charged toxins and replenishment of bicarbonate, wherein the removal of small and charged toxins and replenishment of bicarbonate is provided by changing the replaceable dialysate bag to supply the needed changes in body chemistry,
- a circulating fluid line system including fluid lines connecting each of the housing, the replaceable dialysate bag, and a dialyzer,
- wherein the carbon block comprises of active carbon sorbent, wherein the active carbon sorbent is porous and allows the dialysate to pass through it, wherein the pore structure of the carbon block has a short mean diffusion path length;
- and wherein the carbon block comprising a pulverized active carbon with a binder.
