Claims27
A dialysate regeneration chamber comprising:
- a toxin trap configured to selectively trap toxins and repel select cations, wherein the toxin trap includes an ion-selective urease-immobilized activated carbon fiber.
A dialysate regeneration chamber configured to generate refreshed dialysate from toxin-laden dialysate, the dialysate regeneration chamber comprising:
- a dialysate regeneration fabric including ion-selective urease immobilized carbon fibers, the dialysate regeneration fabric configured to selectively effect substantial uptake of toxins from the toxin-laden dialysate to form a refreshed dialysate, the dialysate regeneration fabric further configured to minimize uptake of non-toxins;
- and
- an outflow for release of the refreshed dialysate.
