Abstract

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

Claims

1. A method for data processing using one or more processors, comprising:

retrieving a predetermined number of stored signals associated with a monitored analyte level;

processing a received signal associated with the monitored analyte level and the retrieved predetermined number of stored signals to determine a tolerance parameter, the tolerance parameter including a predetermined number of acceptable missing data points;

comparing the tolerance parameter to a predetermined tolerance range corresponding to a dynamically varying uncertainty parameter determined based upon a number of data available for determining trend information;

determining that the tolerance parameter is within the predetermined tolerance range by at least determining that no more than the predetermined number of acceptable missing data points from the retrieved predetermined number of stored signals is missing;

in response to determining that the tolerance parameter is within the predetermined tolerance range, determining the trend information; and

providing an indicator on a display of a computing device indicating an analyte level trend based on the determined trend information.

2. The method of claim 1, wherein the tolerance parameter is related to a temporal spacing of the received signal and the retrieved predetermined number of stored signals.

3. The method of claim 1, wherein the trend information is determined based on analyte sensor sensitivity.

4. The method of claim 1, wherein the predetermined tolerance range includes a predetermined number of temporally spaced signals related to the monitored analyte level necessary to determine the trend information.

5. The method of claim 1, wherein each of the retrieved predetermined number of stored signals associated with the monitored analyte level and the received signal associated with the monitored analyte level are temporally separated.

6. The method of claim 1, wherein the trend information includes a projected alarm associated with one or more of a rate of change of the monitored analyte level, or a direction of a projected analyte level.

7. The method of claim 1, including outputting the trend information on an output device separate from the display.

8. The method of claim 1, further comprising administering a therapeutic treatment to a patient based at least on the determined trend information.

9. An analyte monitoring device, comprising:

a data processing unit; and

a memory operatively coupled to the data processing unit, the memory configured for storing instructions which, when executed by the data processing unit, causes the data processing unit to;

retrieve a predetermined number of stored signals associated with a monitored analyte level, process a received signal associated with the monitored analyte level and the retrieved predetermined number of stored signals to determine a tolerance parameter, the tolerance parameter including a predetermined number of acceptable missing data points;

compare the tolerance parameter to a predetermined tolerance range corresponding to a dynamically varying uncertainty parameter determined based upon a number of data available for determining trend information;

determine that the tolerance parameter is within the predetermined tolerance range by at least determining that no more than the predetermined number of acceptable missing data points from the retrieved predetermined number of stored signals is missing;

in response to determining that the tolerance parameter is within the predetermined tolerance range, determine the trend information; and

provide an indicator on a display of the analyte monitoring device indicating an analyte level trend based on the determined trend information.

10. The device of claim 9, wherein the tolerance parameter is related to a temporal spacing of the received signal and the retrieved predetermined number of stored signals.

11. The device of claim 9, wherein the trend information is determined based on analyte sensor sensitivity.

12. The device of claim 9, wherein the predetermined tolerance range includes a predetermined number of temporally spaced signals related to the monitored analyte level necessary to determine the trend information.

13. The device of claim 9, wherein each of the retrieved predetermined number of stored signals associated with the monitored analyte level and the received signal associated with the monitored analyte level are temporally separated.

14. The device of claim 9, wherein the trend information includes a projected alarm associated with one or more of a rate of change of the monitored analyte level, or a direction of a projected analyte level.

15. The device of claim 9, further including an output unit separate from the display, the output unit operatively coupled to the data processing unit to output the trend information.

16. The device of claim 15, wherein the trend information includes one or more of an audible output or a vibratory output.

17. The device of claim 15, wherein the indicator is a trend arrow indicator.

18. The device of claim 17, wherein the trend arrow indicator includes a position from a plurality of positions, each position defined based on +/−

1 mg/dL or +/−

2 mg/d L.

19. The device of claim 9, further comprising instructions which, when executed by the data processing unit, cause the data processing unit to administer a therapeutic treatment to a patient based at least on the determined trend information.

20. A system, comprising:

one or more processors; and

a memory operatively 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;

retrieve a predetermined number of stored signals associated with a monitored analyte level;

process a received signal associated with the monitored analyte level and the retrieved predetermined number of stored signals to determine a tolerance parameter, the tolerance parameter including a predetermined number of acceptable missing data points;

compare the tolerance parameter to a predetermined tolerance range corresponding to a dynamically varying uncertainty parameter determined based upon a number of data available for determining trend information;

determine that the tolerance parameter is within the predetermined tolerance range by at least determining that no more than the predetermined number of acceptable missing data points from the retrieved predetermined number of stored signals is missing;

in response to determining that the tolerance parameter is within the predetermined tolerance range, determine the trend information; and

provide an indicator on a display of a computing device indicating an analyte level trend based on the determined trend information.

21. The system of claim 20, wherein the tolerance parameter is related to a temporal spacing of the received signal and the retrieved predetermined number of stored signals.

22. The system of claim 20, wherein the trend information is determined based on analyte sensor sensitivity.

23. The system of claim 20, further comprising instructions which, when executed by the one or more processors, causes a therapeutic treatment to be administered to a patient based at least on the determined trend information.
