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:

receiving, at a second device, information from a first device that is related to an operational check of one or more components of the first device;

communicating, using the second device, the information related to the operational check of the one or more components of the first device to a third device;

receiving, at the second device, a request from the third device to annunciate an alarm if it is determined by the third device that the one or more components of the first device is not operating based on at least one predetermined criterion; and

annunciating, using the second device, the alarm to alert that the one or more components of the first device is not functioning in accordance with the at least one predetermined criterion.

2. The computer-implemented method of claim 1, wherein the first device is a sensor electronics operatively coupled to an in vivo glucose sensor.

3. The computer-implemented method of claim 2, wherein the second device includes a repeater operatively coupled to the sensor electronics.

4. The computer-implemented method of claim 1, wherein the third device includes one of a data receiver device or an insulin pump.

5. The computer-implemented method of claim 1, wherein the one or more components of the first device include at least one of a microprocessor, a power supply, a glucose sensor, or an electronic component.

6. The computer-implemented method of claim 1, wherein the alarm includes at least one of an audible alarm, a vibratory alarm, or a visual alarm.

7. The computer-implemented method of claim 1, further comprising:

receiving, at the second device, a request from the third device that the operational check of the one or more components of the first device be performed and that the data related to the operational check of the one or more components of the first device be communicated to the third device, wherein the second device is operatively coupled to the first device.

8. The computer-implemented method of claim 1, wherein the information related to the operational check of the one or more components of the first device includes a lack of data received from the first device.

9. The computer-implemented method of claim 1, wherein the operational check includes at least one of a determination of a current, a voltage, or 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, or an electrical or mechanical test of at least one switch of the one or more components.

10. The computer-implemented 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 the proper operating range.

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

receiving, at a second device, data related to an operational check of one or more components of a first device;

retrieving, from the second device, a list including at least one predetermined criterion related to the operational check of the one or more components of the first device;

comparing, using the second device, the data related to the operational check of the one or more components of the first device with the list including the at least one predetermined criterion; and

determining, using the second device, if the one or more components of the first device is operating based on the at least one predetermined criterion.

12. The computer-implemented method of claim 11, further comprising:

requesting, using the second device, annunciation of an alarm at a third device if it is determined by the second device that the one or more components of the first device is not functioning in accordance with the at least one predetermined criterion.

13. The computer-implemented method of claim 12, wherein the third device is operatively coupled to the first device.

14. The computer-implemented method of claim 12, wherein a request for the operational check is received by the third device, and the third device polls the first device to perform the operational check in response to the received request.

15. The computer-implemented method of claim 11, further comprising:

annunciating, using the second device, an alarm if it is determined that the one or more components of the first device is not functioning in accordance with the at least one predetermined criterion.

16. The computer-implemented method of claim 12, wherein the third device is a repeater unit operatively coupled to the first device.

17. The computer-implemented method of claim 11, wherein the one or more components of the first device include at least one of a microprocessor, a power supply, a glucose sensor, or an electric component.

18. The computer-implemented method of claim 15, wherein the alarm includes at least one of an audible alarm, a vibratory alarm, or a visual alarm.

19. The computer-implemented method of claim 11, wherein the operational check includes 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, or an electrical or mechanical test of at least one switch of the one or more components.

20. The computer-implemented method 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 first device, a power supply measurement that defines an acceptable tolerance, and a digital threshold range used to define the proper operating range.

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

determining, using a second device, that one or more components of a first device is not operating properly when data related to an operational check of the one or more components of the first device is not received at the second device; and

annunciating an alarm from at least one of the second device or a third device when it is determined that the one or more components of the first device is not operating properly.
