Abstract

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

Claims

1. A method of determining glucose information, comprising:

receiving a signal associated with a monitored glucose level from an in vivo glucose sensor;

retrieving stored signals associated with the monitored glucose level;

determining a number of corrupt signals of the retrieved stored signals and a number of non-corrupt signals of the retrieved stored signals;

determining that the retrieved stored signals do not exceed a preset tolerance level such that the number of corrupt signals is not more than a predetermined number;

determining a rate of change of the monitored glucose level based on the received signal associated with the monitored glucose level and the non-corrupt signals of the retrieved stored signals; and

delivering medicament using a medical device based on the determined rate of change.

2. The method of claim 1, wherein the rate of change is determined based on glucose sensor sensitivity.

3. The method of claim 1, including displaying the determined rate of change.

4. The method of claim 1, including modifying a display of the determined rate of change.

5. The method of claim 4, wherein modifying the display of the determined rate of change includes modifying a display of a trend arrow indicator.

6. The method of claim 5, wherein modifying the display of the trend arrow indicator includes displaying a change in the trend arrow indicator position.

7. The method of claim 6, wherein the trend arrow indicator position includes one of five or less displayed positions.

8. The method of claim 1, wherein the retrieved stored signals and the received signal associated with the monitored glucose level are temporally separated.

9. An apparatus, comprising:

a data storage unit; and

a data processing unit operatively coupled to the data storage unit including programming to receive a signal associated with a monitored glucose level from an in vivo glucose sensor, retrieve from the data storage unit stored signals associated with the monitored glucose level, determine a number of corrupt signals of the retrieved stored signals and a number of non-corrupt signals of the retrieved stored signals, determine that the retrieved stored signals do not exceed a preset tolerance level such that the number of corrupt signals is not more than a predetermined number, determine a rate of change of the monitored glucose level based on the received signal associated with the monitored glucose level and the non-corrupt signals of the retrieved stored signals, and deliver medicament using a medical device based on the determined rate of change.

10. The apparatus of claim 9, further including a display operatively coupled to the data processing unit to display the determined rate of change.

11. The apparatus of claim 10, wherein the data processing unit includes programming to modify the display of the determined rate of change.

12. The apparatus of claim 11, wherein the data processing unit includes programming to modify the display of a trend arrow indicator based on the determined rate of change.

13. The apparatus of claim 12, wherein the data processing unit includes programming to modify the display of the trend arrow indicator by displaying a change in the trend arrow indicator position.

14. The apparatus of claim 13, wherein the trend arrow indicator position includes one of five or less displayed positions.

15. The apparatus of claim 9, wherein the retrieved stored signals and the received signal associated with the monitored glucose level are temporally separated.
