Abstract
Systems and methods for reducing the burden of recharging on patients and caregivers are provided. The systems and methods use a microbe removal layer upstream of a sorbent cartridge in a sorbent-based dialysis system. The systems and methods can determine whether the bacterial content and remaining capacity of a non-recharged sorbent module are suitable for the sorbent module to be reused safely and effectively without recharging.
Claims19
A system, comprising:
- a sorbent module containing at least zirconium oxide and/or zirconium phosphate;
- a microbe removal layer upstream of the sorbent module;
- and
- a control system programmed to:
- calculate a remaining capacity of the sorbent module following a first dialysis session, wherein the remaining capacity of the sorbent module following the first dialysis session is a function of at least a weight of a patient;
- calculate an estimated capacity of the sorbent module that would be required for a second dialysis session, wherein the second dialysis session would follow the first dialysis session;
- and
- determine if the sorbent module can be reused for the second dialysis session, without recharging the sorbent module, based on the remaining capacity of the sorbent module and the capacity of the sorbent module required for the second dialysis session,
- wherein the capacity of the sorbent module required for the second dialysis session is based on at least an expected dialysate flow rate through the sorbent module for the second dialysis session and expected duration of the second dialysis session.

A method, comprising the steps of:
- determining whether a first sorbent module containing zirconium oxide and/or zirconium phosphate is useable in a present dialysis session;
- wherein the first sorbent module was used in a prior dialysis session;
- and wherein during the prior dialysis session, a microbe removal layer was upstream of the zirconium oxide and/or zirconium phosphate;
- calculating, by a control system, a remaining capacity of the first sorbent module following the prior dialysis session, wherein the remaining capacity of the first sorbent module following the prior dialysis session is a function of at least a weight of a patient;
- calculating, by the control system, an estimated capacity of the first sorbent module that would be required for the present dialysis session, wherein the present dialysis session would follow the prior dialysis session;
- and
- determining, by the control system, if the first sorbent module can be reused for the present dialysis session, without recharging the first sorbent module, based on the remaining capacity of the first sorbent module and the capacity of the first sorbent module required for the present dialysis session,
- wherein the capacity of the first sorbent module required for the present dialysis session is based on at least an expected dialysate flow rate through the first sorbent module for the present dialysis session and expected duration of the present dialysis session.
