Abstract: The invention relates to devices, systems, and methods for estimating a patient BUN level prior to a dialysis session based on data received when introducing an ammonium removal solution through a zirconium phosphate sorbent module. The systems and methods can introduce an ammonia removal solution and determine an ammonia content of the ammonium removal solution effluent to estimate the patient pre-dialysis BUN level.

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.

Abstract: The invention relates to devices, systems, and methods for recharging zirconium phosphate. The devices, system, and methods use a patient pre-dialysis BUN level to set one or more recharge parameters for recharging the zirconium phosphate. The devices, systems, and methods allow for precision recharging of the zirconium phosphate based on the patient pre-dialysis BUN level.

Abstract: The invention relates to systems and methods for estimating a patient urea level at any arbitrary time during dialysis treatment. The systems and methods use either one or more urea sensors or any two of a pH sensor, ammonia sensor, and ammonium sensor to determine an amount of urea removed by a dialysate regeneration system. The systems and methods use the amount of urea removed by the dialysate regeneration system to estimate the patient urea level.

Abstract: An apparatus and method for replenishing urease in a sorbent cartridge for use in sorbent dialysis. The system is configured to allow insertion of a urease pouch, injection of a urease solution, or addition of a urease cartridge, into a dialysis cabinet containing a dialysis flow loop. The urease can be dissolved and the resulting urease solution added to the sorbent cartridge in the flow loop to replenish the urease within the sorbent cartridge. The sorbent cartridge can also comprise other, rechargeable, sorbent materials for removing toxins other than urea from spent dialysate.
