Abstract

Methods and apparatus for providing data processing and control for use in a medical communication system are provided.

Claims

1. A method, comprising:

receiving one or more signals associated with a monitored analyte level from an analyte sensor in fluid contact with bodily fluid under a skin surface;

analyzing a prior signal associated with the analyte sensor and the received one or more signals based on a predetermined signal characteristic including a determination of the received signal below a predetermined level after a determination of the prior signal above a predetermined level; and

transitioning the analyte monitoring device from a sensor insertion state to a sensor removal state based at least in part upon a response to an output data generated based on the analysis of the prior signal and the one or more signals.

2. The method of claim 1, wherein the predetermined signal characteristic includes a determination of a plurality of prior signals above the predetermined level.

3. The method of claim 2, wherein the predetermined signal characteristic includes a determination of the predetermined number of prior signals above the predetermined level for a second predetermined time period.

4. The method of claim 2, wherein the predetermined level includes one of 9 or less ADC counts or 18 or less ADC counts.

5. The method of claim 1, wherein the predetermined signal characteristic includes a signal transition from above the predetermined level to below the predetermined level.

6. The method of claim 1, wherein the predetermined signal characteristic includes a determination of a predetermined number of received signals below the predetermined level.

7. The method of claim 6, wherein the predetermined signal characteristic includes a determination of a predetermined number of received signals below the predetermined level for a first predetermined time period.

8. The method of claim 7, wherein the predetermined signal characteristic further includes a determination of a predetermined number of prior signals above the predetermined level for a second predetermined time period.

9. The method of claim 1, wherein the output data includes an indicator to start one or more processing timers associated with a respective one or more data processing routines.

10. The method of claim 9, wherein the one or more processing timers includes a respective one of a calibration timer, or a sensor expiration timer.

11. An apparatus, comprising:

an analyte sensor in fluid contact with bodily fluid under a skin surface configured to monitor analyte level in the bodily fluid; and

a data processor operatively coupled to the analyte sensor and configured to receive one or more signals associated with the monitored analyte level from the analyte sensor, to analyze a prior signal associated with the analyte sensor and the received one or more signals based on a predetermined signal characteristic including a determination of the received signal below a predetermined level after a determination of the prior signal above the predetermined level, and to transition from a sensor insertion state to a sensor removal state based at least in part upon a response to an output data generated based on the analysis of the prior signal and the one or more signals.

12. The apparatus of claim 11, further including a communication unit operatively coupled to the data processor and configured to communicate one or more of the received signals, the prior signal, and the output data.

13. The apparatus of claim 12, wherein the communication unit includes one of an RF transmitter, an RF receiver, an infrared data communication device, or a short-range data communication device.

14. The apparatus of claim 11, further including a memory operatively coupled to the data processor to store one or more of the received signals associated with the monitored analyte level, the predetermined signal characteristic, the prior signal associated with the monitored analyte level, and the output data.

15. The apparatus of claim 11, wherein the predetermined signal characteristic includes a determination of a predetermined number of received signals below the predetermined level.

16. The apparatus of claim 15, wherein the predetermined signal characteristic includes the determination of a predetermined number of received signals below the predetermined level for a first predetermined time period.

17. The apparatus of claim 16, wherein the predetermined signal characteristic further includes a determination of a predetermined number of prior signals above the predetermined level for a second predetermined time period.

18. The apparatus of claim 11, wherein the predetermined signal characteristic includes a determination of a predetermined number of prior signals above the predetermined level.

19. The apparatus of claim 11, wherein the predetermined signal characteristic includes the determination of a predetermined number of prior signals above the predetermined level for a first predetermined time period.
