Abstract
The invention relates to devices, systems, and methods for recharging zirconium phosphate and/or zirconium oxide in reusable sorbent modules. The devices, systems, and methods provide for precision recharging of the zirconium phosphate and/or zirconium oxide to avoid the need of excess recharge solutions. The devices systems and methods also provide for calculation of the volumes of recharge solution needed for fully recharging the zirconium phosphate and zirconium oxide modules.
Claims14
A method, comprising the steps of:
- recharging a sorbent material within a sorbent module (402, 702) by pumping one or more recharge solutions through the sorbent module;
- wherein a volume and/or a concentration of the one or more recharge solutions is set based on one or more patient parameters and/or one or more dialysis session parameters for a patient and/or dialysis session using the sorbent module.
A system comprising:
- a recharging flow path (401, 701);
- the recharging flow path comprising one or more recharge solution sources;
- the one or more recharge solution sources (405, 406, 705) fluidly connectable to an inlet (403, 703) of a sorbent module (402, 702) containing at least one sorbent material;
- and at least one pump (407, 706) for pumping one or more recharge solutions from the one or more recharge solution sources through the sorbent module;
- and
- a control system, the control system setting a volume and/or concentration of the one or more recharge solutions pumped through the sorbent module necessary to recharge the sorbent material within the sorbent module based on one or more patient parameters and/or one or more dialysis session parameters for a patient and/or dialysis session using the sorbent module.
