Abstract

Embodiments of the invention provide apparatus, systems, and methods wherein pre-event and post-event analyte concentration readings associated with an event are collected and processed to determine a numerical delta. The numerical delta may be displayed on a visual display to aid in a ready determination of the affect that the event (alone or in combination with medication and/or insulin dosages) had on the analyte concentration levels. Medication and/or insulin dosages may be displayed alongside the numerical delta to gauge immediate relationships between numerical delta, dosage, and/or an associated event. Apparatus and systems for calculating and displaying the numerical delta are described, as are other aspects.

Claims

1. A method of identifying and displaying events using a graphical user interface on a hand-held device, the method comprising:

providing a hand-held device including a processor and a display operable to present a graphical user interface (GUI);

receiving at the hand-held device from a measurement device a pre-event glucose concentration reading and a post-event glucose concentration reading, both readings associated with a first event;

calculating a numerical delta between the pre-event glucose concentration reading and the post-event glucose concentration reading for the first event with the hand-held device; and

displaying on the GUI of the hand-held device a time graph including a representation of the first event occurring and the numerical delta associated with the first event wherein the numerical delta is displayed proximate to the representation of the occurrence of the first event to facilitate immediate visual evaluation of a relative magnitude of the numerical delta and an association with the first event, both indicating a significance of the first event.

2. The method of claim 1, wherein the hand-held device comprises a pocket personal computer (HPC), a personal digital assistant (PDA), a smart cellular phone, or a portable computer.

3. The method of claim 1, wherein the measurement device comprises a blood glucose meter (BGM), a continuous glucose meter (CGM), or a pump/CGM combination.

4. The method of claim 1, wherein the receiving at the hand-held device from the measurement device comprises receiving at the hand-held device from the measurement device via a wireless connection, a USB connection, or a download from a memory article the pre-event glucose concentration reading and the post-event glucose concentration reading.

5. The method of claim 1 further comprising displaying on the GUI, an insulin dose associated with the first event proximate to the representation of the occurrence of the first event along with the numerical delta.

6. The method of claim 1 further comprising:

determining if the numerical delta is within a predetermined acceptable range; and

indicating within the GUI that the numerical delta is within the predetermined acceptable range with a first indicator.

7. The method of claim 6 wherein the first indicator comprises a first displayed color or a first displayed graphic.

8. The method of claim 1 further including providing an indicia in the GUI associated with the first event, the indicia designating the first event as unacceptable if a magnitude of the numerical delta exceeds a predetermined threshold value wherein the indicia includes at least one of a display color and a graphic.

9. The method of claim 1 wherein the first event is a meal event and the pre-event glucose concentration reading is a preprandial glucose concentration reading and the post-event glucose concentration reading is a postprandial glucose concentration reading.

10. The method of claim 1 wherein the first event is an exercise regimen.

11. The method of claim 1 wherein the GUI displays the pre-event glucose concentration level and the post-event glucose concentration level on a first axis against time on a second axis, and the numerical delta is displayed adjacent to a peak in the time graph of the glucose concentration level over time.

12. The method of claim 11 wherein an insulin dosage is also displayed adjacent to the peak in the time graph of the pre-event glucose concentration level and the post-event glucose concentration level.

13. The method of claim 1 wherein the numerical delta is normalized as against another measure associated with the first event.

14. A method of identifying and displaying events using a graphical user interface on a hand-held analyte meter, the method comprising:

providing a hand-held analyte meter including a processor and a display operable to present a graphical user interface (GUI);

measuring a pre-event glucose concentration reading from a sensor of the hand-held analyte meter and a post-event glucose concentration reading from a sensor of the hand-held analyte meter, both readings associated with a first event;

calculating a numerical delta between the pre-event glucose concentration reading and the post-event glucose concentration reading for the first event with the hand-held analyte meter; and

displaying on the GUI of the hand-held analyte meter a time graph including a representation of the first event occurring and the numerical delta associated with the first event wherein the numerical delta is displayed proximate to the representation of the occurrence of the first event to facilitate immediate visual evaluation of a relative magnitude of the numerical delta and an association with the first event, both indicating a significance of the first event.

15. The method of claim 14, wherein the hand-held analyte meter comprises a blood glucose meter (BGM), a continuous glucose meter (CGM), or a pump/CGM combination.

16. The method of claim 14 further comprising displaying on the GUI, an insulin dose associated with the first event proximate to the representation of the occurrence of the first event along with the numerical delta.

17. A method of identifying and displaying events using a graphical user interface on a hand-held device, the method comprising:

providing a hand-held device including a processor and a display operable to present a graphical user interface (GUI);

receiving at the hand-held device a pre-event analyte reading from an analyte meter and a post-event analyte reading from an analyte meter, both readings associated with a first event;

calculating a numerical delta between the pre-event analyte reading and the post-event analyte reading for the first event with the hand-held device; and

displaying on the GUI of the hand-held device a time graph including a representation of the first event occurring and the numerical delta associated with the first event wherein the numerical delta is displayed proximate to the representation of the occurrence of the first event to facilitate immediate visual evaluation of a relative magnitude of the numerical delta and an association with the first event, both indicating a significance of the first event.

18. The method of claim 17, wherein the hand-held device comprises a pocket personal computer (HPC), a personal digital assistant (PDA), a smart cellular phone, or a portable computer.

19. The method of claim 17 wherein the pre-event analyte reading comprises a measured concentration or amount of lactate, keytones, total cholesterol, uric acid, lipids, triglycerides, high density lipoprotein (HDL), low density lipoprotein (LDL), Hemoglobin A1c, or alcohol.

20. The method of claim 17 further comprising displaying on the GUI, a medication dose associated with the first event proximate to the representation of the occurrence of the first event along with the numerical delta.
