Abstract

Embodiments of the present invention provide methods, apparatuses, and systems associated with detecting, analyzing, and/or displaying historical glucose levels and/or trends in a body.

Claims

1. A method, comprising:

receiving a plurality of glucose values of an individual for a plurality of points of time over a defined time period;

determining, using an electronic monitoring unit, for the plurality of points of time over the defined time period the relative integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia;

identifying, using the electronic monitoring unit, a glucose level condition of the individual based on said relative integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia; and

providing, using the electronic monitoring unit, a notification of the identified glucose level condition, wherein said notification comprises a display of a unified graphical representation of the integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia.

2. The method of claim 1, wherein said defined time period has a duration of 5 minutes to 90 days.

3. The method of claim 1, wherein said defined time period comprises a period of minutes or hours repeated over a period of days or weeks.

4. The method of claim 1, wherein said notification further comprises an audible, visual, or vibratory alarm.

5. The method of claim 1, wherein said graphical representation is displayed on an electronic monitoring unit.

6. The method of claim 1, wherein said graphical representation is displayed on a personal computer by the individual.

7. The method of claim 1, wherein said graphical representation is displayed on a computing device or on printed reports by a health professional.

8. The method of claim 1, wherein the integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia are displayed using different font sizes and/or colors corresponding to the regions of the display and/or the displayed values.

9. The method of claim 1, wherein the integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia are displayed in dynamic font sizes and wherein the font sizes are representative of relative values of the integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia.

10. The method of claim 1, wherein the integrated percentage of normoglycemia is displayed as a number in a square, the integrated percentage of hyperglycemia is displayed as a number in an arrow pointing upward, and the integrated percentage of hypoglycemia is displayed as a number in an arrow pointing downward.

11. The method of claim 10, wherein the square and/or one or both of the arrows is colored.

12. The method of claim 10, wherein the square and the arrows are dynamically sized and wherein the sizes are representative of relative values of the integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia.

13. The method of claim 1, wherein said notification further comprises a display of text indicating a condition of concern.

14. The method of claim 1, wherein said notification further comprises an indication of a relative level of concern based on the identified glucose level condition.

15. The method of claim 1, wherein said determining for the plurality of points of time over the defined time period the relative integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia comprises determining the integrated areas for each region of hyperglycemia, hypoglycemia, and normoglycemia values over the defined time period and expressing those values as a percentage of the total area over the defined time period.

16. A method, comprising:

receiving from a glucose sensing device a plurality of glucose values of an individual for a plurality of points of time over a defined time period;

determining with an electronic monitoring unit for the defined period of time a hyperglycemia index value determined by summing a difference between a measured glucose value and a predefined hyperglycemia threshold for each of the plurality of points of time, if any, at which the measured glucose value is in excess of a predefined hyperglycemia threshold value to arrive at a hyperglycemia index value;

determining with the electronic monitoring unit for the defined period of time a hypoglycemia index value determined by summing a difference between a measured glucose value and a predefined hypoglycemia threshold for each of the plurality of points of time, if any, at which the measured glucose value is less than a predefined hypoglycemia threshold value to arrive at a hypoglycemia index value;

determining with the electronic monitoring unit for the defined period of time a normoglycemia index value determined by summing a difference between the measured glucose value and the closest threshold value, whether the closest threshold value is the predefined hyperglycemia threshold or the predefined hypoglycemia threshold, for each of the plurality of points of time, if any, at which a measured glucose value is within a predefined range of values between the predefined hyperglycemia threshold and the predefined hypoglycemia threshold to arrive at a normoglycemia index value; and

displaying the hyperglycemia index value, the hypoglycemia index value, and the normoglycemia index value on an electronic monitoring unit associated with the glucose sensing device, wherein displaying comprises displaying a unified, graphical representation of the integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia.

17. The method of claim 16, further comprising identifying a glucose level condition of the individual based on the hyperglycemia index value, the hypoglycemia index value, and the normoglycemia index value;

and

providing a notification of the glucose level condition to the individual.

18. An apparatus, comprising:

a glucose sensing device coupled to an electronic monitoring unit, said electronic monitoring unit comprising a storage medium and a plurality of programming instructions stored in the storage medium adapted to program the electronic monitoring unit to enable the electronic monitoring unit to;

receive a plurality of glucose values of an individual for a plurality of points of time over a defined time period;

determine for the plurality of points of time over the defined time period the relative integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia;

identify a glucose level condition of the individual based on said relative integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia; and

provide a notification of the identified glucose level condition, wherein said notification comprises a display of a unified graphical representation of the integrated percentages of hyperglycemia, hypoglycemia, and normoglycemia.
