Claims20
A system capable of removing wastes from blood, the system comprising:
- a dialysis chamber comprising a dialysate compartment, a blood compartment, and a semi-permeable membrane disposed between the dialysate compartment and the blood compartment;
- and
- a dialysate regeneration chamber comprising a dialysate regeneration fabric including an ion barrier and an immobilized urease, wherein the dialysate regeneration chamber is coupled to the dialysis chamber via a tubing system.
A system for removing wastes from blood, the system comprising:
- a dialysis chamber comprising a dialysate compartment, a blood compartment, and a semi-permeable membrane disposed between the dialysate compartment and the blood compartment;
- and
- a dialysate regeneration chamber comprising a dialysate regeneration fabric including an ion barrier and one or more ion selective activated carbon fibers, wherein the dialysate regeneration chamber is coupled to the dialysis chamber via a conduit.
A system for removing wastes from blood, the system comprising:
- a dialysis chamber comprising a dialysate compartment, a blood compartment, and a semi-permeable membrane disposed between the dialysate compartment and the blood compartment;
- and
- a dialysate regeneration chamber comprising a dialysate regeneration fabric including a plurality of hydrocarbon moieties, one or more activated carbon fibers, an immobilized urease attached to the activated carbon fibers via a linker, and an ion exchange resin to increase a negative charge along the dialysate regeneration fabric, wherein the dialysate regeneration chamber is coupled to the dialysis chamber via a conduit.
