Abstract

Methods, devices, and kits are provided for mitigating single point failure of at least one device in an analyte monitoring system.

Claims

1. A computer-implemented method for mitigating single point failure of at least one device in an analyte monitoring system, comprising:

providing a request, from a first device to a second device, that a functionality check of one or more components of a third device be performed, wherein the functionality check includes communicating, from the third device to the second device, data related to results of the functionality check;

receiving, at the first device, the data related to the results of the functionality check from the second device;

determining, by the first device, that the one or more components of the third device is not functioning in accordance with at least one predetermined criterion; and

providing, to the second device, a request from the first device that an alarm function be initiated to alert a user that the one or more components of the third device is not functioning in accordance with the at least one predetermined criterion.

2. The method of claim 1, wherein the first device comprises one of a receiver device or an insulin pump.

3. The method of claim 1, wherein the second device is a repeater.

4. The method of claim 1, wherein the third device is a continuous glucose monitor.

5. The method of claim 1, wherein the request from the first device to the second device is provided over a RF communication link.

6. The method of claim 1, wherein the data related to the results of the functionality check includes a lack of data being received from the third device.

7. The method of claim 1, wherein the data related to the results of the functionality check include at least one of a determination of a current, a voltage, and a resistance that is measured across an electrical circuit in the one or more components, applying an input to the one or more components and receiving an output from the one or more components, a digital check of the one or more components, a checksum of a memory of the first device, a self-test output check of the one or more components, and an electrical or mechanical test of at least one switch of the one or more components.

8. The method of claim 1, wherein the at least one predetermined criterion includes at least one of a current, a voltage, and a resistance threshold used to define a proper operating range of the first device, a power supply measurement that defines an acceptable tolerance, and a digital threshold range used to define a proper operating range.

9. The method of claim 1, further comprising initiating an alarm of the first device to alert the user that the one or more components of the third device is not functioning in accordance with the at least one predetermined criterion.

10. The method of claim 1, wherein the third device comprises an analyte sensor including a plurality of electrodes, wherein the plurality of electrodes include a working electrode comprising an analyte-responsive enzyme and a mediator, wherein at least one of the analyte-responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and wherein at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.

11. An apparatus, comprising:

a communication interface;

one or more processors; and

a memory coupled to the one or more processors, the memory storing instructions which, when executed by the one or more processors, causes the one or more processors to;

provide a request to a second device, using the communication interface, that a functionality check of one or more components of a third device be performed, wherein the functionality check includes communicating, from the third device to the second device, data related to results of the functionality check;

receive, using the communication interface, the data related to the results of the functionality check from the second device;

determine that the one or more components of the third device is not functioning in accordance with at least one predetermined criterion; and

provide, to the second device using the communication interface, a request that an alarm function be initiated to alert a user that the one or more components of the third device is not functioning in accordance with the at least one predetermined criterion.

12. The apparatus of claim 11, further comprising an insulin pump.

13. The apparatus of claim 11, wherein the second device is a repeater.

14. The apparatus of claim 11, wherein the third device is a continuous glucose monitor.

15. The apparatus of claim 11, wherein the communication interface is a RF communication interface.

16. The apparatus of claim 11, wherein the data related to the results of the functionality check includes a lack of data being received from the third device.

17. The apparatus of claim 11, wherein the data related to the results of the functionality check include at least one of a determination of a current, a voltage, and a resistance that is measured across an electrical circuit in the one or more components, applying an input to the one or more components and receiving an output from the one or more components, a digital check of the one or more components, a checksum of the memory of the apparatus, a self-test output check of the one or more components, and an electrical or mechanical test of at least one switch of the one or more components.

18. The apparatus of claim 11, wherein the at least one predetermined criterion includes at least one of a current, a voltage, and a resistance threshold used to define a proper operating range of the apparatus, a power supply measurement that defines an acceptable tolerance, and a digital threshold range used to define a proper operating range.

19. The apparatus of claim 11, further comprising an alarm coupled to the one or more processors, and wherein the memory storing instructions which, when executed by the one or more processors, causes the one or more processors to initiate the alarm coupled to the one or more processors to alert the user that the one or more components of the third device is not functioning in accordance with the at least one predetermined criterion.

20. The apparatus of claim 11, wherein the third device comprises an analyte sensor including a plurality of electrodes, wherein the plurality of electrodes include a working electrode comprising an analyte-responsive enzyme and a mediator, wherein at least one of the analyte-responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and wherein at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.
