Abstract

A dialysis authentication and management system comprising at least one dialysis component having at least one authentication component affixed thereon. The dialysis component can be any one of a dialyzer, sorbent cartridge, recharger or any other dialysis component. The authentication component can be selected from the group of a radio-frequency identification marker, a bar code, a one-wire security component, and a wireless authentication component. The authentication system can ensure that all components used are in proper usable condition and/or certified. The system can also manage the recharging of rechargeable components, and optionally manage dialysis therapy.

First claim

We claim:

1. A dialysis authentication system, comprising:
a sorbent cartridge containing one or more sorbent materials, and a recharger for recharging one or more sorbent materials in the sorbent cartridge;
at least one authentication component for managing a sorbent-based dialysis system containing data corresponding to at least one of the sorbent cartridge or recharger;
at least one identifier to read the data of the at least one authentication component; and
a processor to receive the data from the at least one identifier, wherein the data are processed by the processor for making a determination regarding the at least one of the sorbent cartridge or recharger;
wherein the data from the authentication component and a patient authentication component are communicated to the processor; wherein the processor executes instructions for determining an optimized setting of the dialysis system for a patient regarding the sorbent cartridge or recharger; wherein the optimized setting of the dialysis system comprises whether any one of the sorbent cartridge is fully recharged, whether the sorbent cartridge matches the dialysis system, whether settings of the dialysis system are proper for the patient, whether the sorbent cartridge matches a patient prescription, a blood flow rate, sorbent cartridge size, ultrafiltration rate, ultrafiltration profile, and combinations thereof.

2. The dialysis authentication system in claim 1 , wherein the authentication component is affixed on any one or more selected from the group of a dialyzer, sorbent cartridge, and recharger.

3. The dialysis authentication system of claim 1 , wherein the authentication component is selected from a group comprising a radio-frequency identification (RFID) marker, a bar code, a one-wire security component, and a wireless authentication component.

4. The dialysis authentication system of claim 1 wherein the authentication component contains an embedded memory.

5. The dialysis authentication system of claim 1 , wherein the authentication component contains a radio-frequency identification (RFID) chip and a Memory chip bonded in a smart card.

6. The dialysis authentication system of claim 1 , wherein the authentication component is readable and writable that allows the data of the sorbent cartridge or recharger to be updated.

7. The dialysis authentication system of claim 1 , wherein the processor determines non-certified components or counterfeit components based on the data received from the authentication component.

8. The dialysis authentication system in claim 1 , wherein the patient authentication component is one of an implantable device, a card-like device, and a wrist-band device.

9. The dialysis authentication system of claim 1 , wherein the processor determines one or more of whether the sorbent cartridge or recharger matches the patient, whether a setting of the sorbent cartridge or recharger is proper, and any changes of the setting to be made for optimized performance, based on the data received from the authentication component and the patient authentication component.

10. The dialysis authentication system in claim 1 , wherein the identifier is affixed onto a second dialysis component to read the authentication component, and the processor determines whether the dialysis component having the authentication component matches the second dialysis component.

11. The dialysis authentication system of claim 1 , wherein the identifier is a multimode type reader that is able to communicate with at least two different types of the authentication component.

12. The dialysis authentication system of claim 1 , wherein the at least one authentication component includes two or more authentication components, and the identifier distinguishes the two or more authentication components from each other.

13. A method of managing a dialysis system for performing dialysis via radios signals, comprising:
providing the dialysis authentication system of claim 1 ;
reading a first data from a first authentication component corresponding to a first dialysis component by the at least one identifier;
reading a second data from a second authentication component corresponding to a second dialysis component or the patient by the at least one identifier;
receiving the first data and the second data by the processor from the at least one identifier;
making a determination by the processor based on the first data and the second data regarding the first dialysis component in view of the second dialysis component or the patient; and
controlling a setting of the first dialysis component for optimized performance in view of the second dialysis component or the patient.

14. The method of claim 13 , further comprising storing data in at least one of the first authentication component and the second authentication component regarding the dialysis, during or after the dialysis ends.

15. A method comprising the steps of:
providing the dialysis authentication system of claim 1 ;
reading data from the at least one authentication component affixed on a rechargeable component used in sorbent based dialysis by the at least one identifier;
communicating the data derived from the at least one authentication component to the processor;
determining whether to start a recharge of the rechargeable component by the recharger based on the data received by the processor; and
controlling the recharger used to recharge the rechargeable component to selectively recharge based on the determination made by the processor.

16. The method of claim 15 , wherein the step of determining further comprises the step of determining one or more of whether the rechargeable component is stored too long using a predetermined standard, whether the rechargeable component is not fully recharged, and whether the rechargeable component reaches a limit of recharging.

17. A method comprising:
providing the dialysis authentication system of claim 1 ;
reading data of an authentication component affixed on a multi-use cartridge by an identifier affixed on a hemodialysis system;
communicating the data of the authentication component to the processor by the identifier;
determining by the processor whether the cartridge is to be properly used according to the data communicated to the processor; and
controlling a hemodialysis therapy according to the determination made by the processor.

18. The method of claim 17 , wherein the step of determining comprises determining one or more of whether the cartridge is stored too long according to a predetermined standard, whether the cartridge is not fully recharged, whether the cartridge reaches a limit of recharging, and whether the cartridge matches a patient.

19. The dialysis authentication system of claim 1 , wherein the patient authentication component stores whether ammonia breakthrough occurred in at least one prior session.

20. The dialysis authentication system of claim 19 , wherein if ammonia breakthrough occurred in the at least one prior session, the processor determines that the optimized setting includes a larger sorbent cartridge size.
