Abstract

A dialysis authentication 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, or recharger. The authentication component can be selected from the group comprising a radio-frequency identification marker, a bar code, a one-wire security component, and a wireless authentication component.

Claims

1. A dialysis authentication system comprising:

a sorbent cartridge containing one or more sorbent materials;

a recharger for recharging one or more sorbent materials within the sorbent cartridge;

at least one authentication component affixed on any one or both of the sorbent cartridge and the recharger; and

a processor monitoring any one or more features selected from the group consisting of;

whether the sorbent cartridge has been recharged, a number of times the sorbent cartridge has been recharged, a sorbent cartridge-specific unique identifier, usage of the sorbent cartridge, a number of times the sorbent cartridge is disconnected and reconnected to the system, contents of the sorbent cartridge, a length of time between uses of the sorbent cartridge, usage of a counterfeit sorbent cartridge, a product history of the sorbent cartridge, and combinations thereof.

2. The dialysis authentication system of claim 1, further comprising a dialyzer.

3. The dialysis authentication system of claim 1, wherein the sorbent cartridge comprises at least one reusable module.

4. The dialysis authentication system of claim 1, wherein the authentication component is any one or more selected from the group consisting of a radio-frequency identification marker, a bar code, a one-wire security component, and a wireless authentication component.

5. The dialysis authentication system of claim 1, further comprising a memory device.

6. The dialysis authentication system of claim 1, further comprising a reader to read the authentication component.

7. The dialysis authentication system of claim 1, further comprising a writer to write to the authentication component.

8. The dialysis authentication system of claim 1, wherein the authentication component includes one or more selected from the group consisting of:

A. a sorbent cartridge-specific or recharger-specific unique identifier;

B. a manufacturer-specific unique identifier;

C. a user-specific unique identifier; and

D. an expiration date corresponding to the sorbent cartridge to which the authentication component is affixed.

9. The dialysis authentication system of claim 8, wherein the processor correlates the sorbent cartridge-specific or recharger-specific identifier with at least one or both of

A. the manufacturer-specific unique identifier;

and

B. the user-specific unique identifier.

10. The dialysis authentication system of claim 1, wherein the processor monitors one or more selected from the group consisting of

A. usage of the sorbent cartridge;

B. the number of times the sorbent cartridge is disconnected and reconnected to the system;

C. contents of the sorbent cartridge; and

D. a length of time between uses of the sorbent cartridge.

11. The dialysis authentication system of claim 1, wherein the authentication component detects the usage of a counterfeit sorbent cartridge.

12. The dialysis authentication system of claim 11, wherein the authentication component disables the usage of the counterfeit sorbent cartridge.

13. The dialysis authentication system of claim 1, further comprising a memory device to determine the product history of the sorbent cartridge.

14. The dialysis authentication system of claim 1, wherein the authentication component is built into any one or both of the sorbent cartridge and the recharger.

15. The dialysis authentication system of claim 6 comprising more than one reader.

16. The dialysis authentication system of claim 13, wherein the memory device is one or both of a memory component integrated with the authentication component, and a memory component separate from the authentication component.

17. The dialysis authentication system of claim 13, wherein the memory device comprises a database to track one or more sorbent cartridge.

18. The dialysis authentication system of claim 1, wherein the authentication component is placed inside the sorbent cartridge.

19. The dialysis authentication system of claim 13, wherein the system determines how many times the sorbent cartridge has been used.

20. The dialysis authentication system of claim 19, wherein the system alerts a user if the sorbent cartridge has met one or more of the following conditions:

A. has been used more than a pre-set number of times;

B. has reached an expiration date of the sorbent cartridge; and

C. the length of time between uses of the sorbent cartridge is greater than a pre-set length of time.

21. The dialysis authentication system of claim 1, wherein the authentication component includes information on whether the sorbent cartridge has been recharged.

22. The dialysis authentication system of claim 1, wherein the authentication component includes information on whether the sorbent cartridge has been previously used.

23. The dialysis authentication system of claim 1, wherein the authentication component includes information on the last use date of any one or more of the sorbent cartridge, the recharger and the processor.

24. The dialysis authentication system of claim 13, wherein the memory device tracks performance data of any one or more of the sorbent cartridge, the recharger and the processor.

25. The dialysis authentication system of claim 6, wherein the authentication component requires electrical contact with the reader for the authentication component to communicate with the reader;

and a spring is placed on the sorbent cartridge such that when the sorbent cartridge is attached in a fluid flow path, the spring causes the authentication component to come into electrical contact with the reader.

26. The dialysis authentication system of claim 6, wherein the reader is affixed to the recharger.

27. The dialysis authentication system of claim 1, wherein the authentication component includes performance information for the sorbent cartridge.

28. The dialysis authentication system of claim 1, wherein the recharger reads the authentication component and determines whether the sorbent cartridge has reached a maximum allowable number recharges.

29. The dialysis authentication system of claim 1, wherein the recharger writes data to the authentication component selected from the group of database information and performance data for the sorbent cartridge.

30. The dialysis authentication system of claim 1, wherein the sorbent cartridge comprises a first module and a second module detachable from each other, the first module having a first sorbent material and the second module having a second sorbent material.

31. The dialysis authentication system of claim 30, further comprising a first connector connectable to the first module and the recharger wherein the recharger recharges the first sorbent material inside of the first module while the first module is detached from the second module.

32. The dialysis authentication system of claim 30, further comprising a second connector connectable to the second module and the recharger wherein the recharger recharges the second sorbent material inside of the second module while the second module is detached from the first module.

33. The dialysis authentication system of claim 1, wherein the sorbent cartridge has a modular design containing one or more sorbent materials dispersed across at least two different modules wherein the modules are connectable to form a unitary body.

34. The dialysis authentication system of claim 1, wherein the recharger recharges the one or more sorbent materials in-line within a module of the sorbent cartridge.
