Abstract

An electronic device may selectively disable a bolus advice process according to which the electronic device recommends delivery of a bolus amount of a drug to a body of a user based on a plurality of factors including glucose concentration of the user. The electronic device may include a glucose measuring facility configured to measure glucose concentration of a body fluid sample, and a processor including a memory having instructions stored therein that comprise the bolus advice process. The memory may further have instructions stored therein that are executable by the processor to request a glucose concentration measurement by the glucose measurement facility prior to executing, or as part of, the bolus advice process, and to disable execution of the bolus advice process if a glucose concentration value resulting from the requested glucose concentration measurement is less than a threshold value.

determining a display color based on the measured or computed value relative to at least one limit or range, and

changing a color of at least a portion of the display to the display color when displaying the measured or computed value or a message identifying the value.

6. The method of claim 5 wherein the electronic device includes a medical device that measures an analyte concentration in a liquid sample.

7. The method of claim 6 wherein the medical device is a blood glucose meter that measures glucose concentration in blood samples,

and wherein determining a display color based on the measured or computed value comprises determining a display color based on a measured glucose concentration relative to at least a target blood glucose range.

8. The method of claim 7 wherein determining a display color comprises selecting a first color if the measured glucose concentration is within the target blood glucose range.

9. The method of claim 8 wherein determining a display color comprises selecting a second color different from the first color if the measured glucose concentration is between the target blood glucose range and a low blood glucose value.

10. The method of claim 9 wherein determining a display color comprises selecting a third color different from the first and second colors if the measured glucose concentration is below the low blood glucose value.

11. The method of claim 10 further comprising controlling the display to display a warning message if the measured blood glucose concentration is below the low blood glucose value.

12. The method of claim 10 wherein the low blood glucose value is a hypoglycemic blood glucose threshold.

13. The method of claim 8 wherein determining a display color comprises selecting a fourth color different from the first color if the measured glucose concentration is between the target blood glucose range and a high blood glucose value.

14. The method of claim 13 further comprising controlling the display to display a warning message along with the fourth color if the measured blood glucose concentration is below above the high blood glucose value.

15. The method of claim 14 wherein the high blood glucose value is a hyperglycemic blood glucose threshold.

16. The method of claim 5 wherein determining a measured or computed value comprises computing a value, or receiving a computed value, of a quantity of a drug to be delivered to a body.
