Abstract

A four-part method for analyzing data of a patient'"'"'s blood glucose (BG) tests or other parameters e.g. carbohydrate intakes and discrete insulin doses (boluses): 1. An LCD-button on the portable glucose meter or insulin pump, that allows flagging or assigning a category to each blood glucose test at test-time. Examples of categories: pre-meal BG tests, post-meal BG tests. 2. In the computer-based downloading program, features for changing the boundaries of the meal-oriented time-intervals by the faster methods of: a) mouse-dragging the time-boundary lines on a scatter chart, b) placing stretchable rectangles around the data points of interest. 3. Features in the computer-based downloading program, for digitally identifying the time of the meal and digitally assigning the category to the pre-meal BG tests and to the post-meal BG tests. 4. Features in the computer-based downloading program, for statistically analyzing and graphically-displaying the differently-categorized data separately or together in combinations.

Claims

1. A method for manually assigning digital categories to blood glucose tests (BG'"'"'s) in a diabetic patient'"'"'s portable blood glucose meter, insulin pump or other portable device by the patient at the time of testing by manual activation of a physical button or a selector on an LCD screen, wherein the categories may include but are not limited to pre-meal, post-meal, disregard, or other categories determined by the user, or wherein the button or selector has no label but its meaning may be understood by the patient and the practitioner, wherein the activation of the button or selector may allow one of two values or may allow a text string.

2. The method of claim 1 wherein all the methods described for BG'"'"'s may also be used for meal boluses, correction boluses, and carbohydrate intakes.

4. The method of claim 1 wherein the category is a variable having two possible values, indicating whether the button or selector was pressed or not pressed.

5. The method of claim 4 wherein the category variable is binary.

6. The method of claim 1 wherein there is a plurality of category variables each having two possible values, indicating that the selector was activated or not activated.

7. The method of claim 1 wherein the category variable or plurality of category variables are short text strings.

8. The method of claim 7 wherein each category chosen for each variable is chosen from a fixed drop-down list in the LCD screen of the portable device.

9. The method of claim 7 wherein each category is chosen from a drop-down list in the LCD screen that can be added to through an alphanumeric input feature in the portable device.

10. The method of claim 9 wherein the portable device has alphanumeric input capability by virtue of being built into a palm device or a blackberry device.

none”

flagged”
