  • INCREASED OPERATIONAL CAPABILITIES OF A DIALYSIS SYSTEM
    Publication number: 20220323661
    Abstract: The disclosure relates to systems and methods for increasing the functional capabilities of a sorbent-based dialysis system. The systems and methods allow for the mode of operation of the dialysis system to be switched between single pass mode and a sorbent based multi-pass mode by controlling an amount of water added to the dialysate between 0% to 100% of the dialysate flow rate.

  • Recharge solution for zirconium phosphate
    Patent number: 11213616
    Abstract: The invention relates to devices, systems, and methods for mixing one or more solutions to generate a recharge solution having specified concentrations of a sodium salt and acid for recharging and disinfecting zirconium phosphate in reusable sorbent modules. The devices, systems, and methods can generate a recharge solution by a sorbent recharger that is introduced through the sorbent module to recharge and to disinfect the zirconium phosphate.
