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 a signal associated with an analyte level of a user;

determining whether the received signal deviates from a predetermined signal characteristic;

determining an operational state associated with an analyte monitoring device;

comparing a prior signal associated with the analyte level of the user to the received signal; and

generating an output data associated with the operational state of the analyte monitoring device based on one or more of the received signal and the prior signal.

2. The method of claim 1 wherein the predetermined signal characteristic includes a signal level transition from below a first predetermined level to above the first predetermined level, a signal level transition from above a second predetermined level to below the second predetermined level, a transition from below a predetermined signal rate of change threshold to above the predetermined signal rate of change threshold, or a transition from above the predetermined signal rate of change threshold to below the predetermined signal rate of change threshold.

3. The method of claim 2 wherein the first predetermined level and the second predetermined level each includes one of approximately 9 ADC counts or approximately 18 ADC counts.

4. The method of claim 1 wherein the predetermine signal characteristic includes a transition from below a predetermined level to above and wherein the signal is maintained above the predetermined level for a predetermined period of time.

5. The method of claim 4 wherein the predetermined period of time includes one of approximately 10 seconds, 30 seconds, or less than 30 seconds, or greater than 30 seconds.

6. The method of claim 1 wherein the operational state includes a no detected sensor state, or a sensor presence state.

7. The method of claim 1 wherein the output data includes a user notification alert.

8. 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.

9. The method of claim 8 wherein the one or more processing timers includes a respective one of a calibration timer, or a sensor expiration timer.

10. The method of claim 1 including receiving a user input data based on the output data.

11. The method of claim 10 wherein the user input data includes a user confirmation of one of the change in operational state or no change in operational state.

12. The method of claim 10 including modifying the operational state.

13. The method of claim 12 wherein the operational state is modified based on one of the received user input data, or based on the generated output data.

14. The method of claim 1 including presenting the output data.

15. The method of claim 14 wherein presenting the output data includes one or more of visually presenting the output data, audibly presenting the output data, vibratorily presenting the output data, or one or more combinations thereof.

16. The method of claim 1 wherein the analyte level includes glucose level of the user.

17. The method of claim 1 wherein the operational state includes one of an analyte sensor removal state, an analyte sensor insertion state, an analyte sensor dislocation state, an analyte sensor insertion with an associated transient signal state, or an analyte sensor insertion with an associated stabilized signal state.

18. An apparatus, comprising a data processing unit including a data processor configured to determine whether a received signal associated with an analyte level of a user deviates from a predetermined signal characteristic, determine an operational state associated with an analyte monitoring device, compare a prior signal associated with the analyte level of the user to the received signal, and generate an output data associated with the operational state of the analyte monitoring device based on one or more of the received signal or the prior signal.

19. The apparatus of claim 18 wherein the data processing unit includes a communication unit operatively coupled to the data processor and configured to communicate one or more of the received signal, the prior signal, and the output data associated the operational state of the analyte monitoring device.

20. The apparatus of claim 19 wherein the communication unit includes one of an rf transmitter, an rf receiver, an infrared data communication device, a Bluetooth data communication device, or a Zigbee data communication device.

21. The apparatus of claim 18 wherein the data processing unit includes a storage unit operatively coupled to the data processor to store one or more of the received signal associated with the analyte level, the predetermined signal characteristic, the operational state associated with the analyte monitoring device, the prior signal associated with the analyte level of the user, or the output data associated with the operational state of the analyte monitoring device.
