Abstract

A blood glucose management device is operable to seamlessly provide a sequence of at least two displays of data relating to one or more blood glucose measurements to a user, upon minimal user interaction, with the blood glucose management device.

Claims

1. A portable blood glucose management device, comprising:

a housing including a display and a user entry means for receiving user input;

a processor in the housing operatively connected to the display and the user entry means; and

a memory connected with the processor,

wherein the processor is configured to;

produce on the display a representation of a blood glucose measurement that may be stored in the memory,

associate the blood glucose measurement with at least one other blood glucose measurement that may be stored in the memory to obtain associated blood glucose measurements, and

seamlessly produce on the display a graphical representation of the associated blood glucose measurements for a period of time automatically and without user input to the user input means after producing the representation of the blood glucose measurement, and

wherein the processor is further configured to;

associate the blood glucose measurement and a plurality of blood glucose measurements in the memory with a context group in the memory, and

seamlessly and sequentially produce on the display a plurality of graphical representations of blood glucose measurements in the context group for a period of time automatically and without user input to the user input means after producing the graphical representation of the associated blood glucose measurements.

2. The device of claim 1, wherein the processor is further configured to seamlessly produce on the display advice directed to a currently displayed one of the graphical representations upon user input into the user entry means.

3. The device of claim 2, wherein the advice includes an interpretation of the blood glucose measurements in the currently displayed graphical representation relative to pre-defined blood glucose limits.

4. The device of claim 3, wherein the advice includes a recommended dietary change.

5. The device of claim 2, wherein the user entry means includes at least two buttons, and the user input consists of one press of one button of the user entry means.

6. The device of claim 1, wherein the plurality of graphical representations includes xy-graphs of blood glucose measurements in the context group for at least one of a seven day time period and a thirty day time period.

7. The device of claim 1, wherein the entry means includes at least two buttons located adjacent to the display, and further wherein the processor is configured to assign a function to each of the at least two buttons and to produce the assigned functions on the display, and wherein the assigned functions depend on the graphical representation being currently produced on the display.

8. The device of claim 1, wherein the context groups include at least two or more of a fasting context group, a prandial context group, an exercise context group, a pre-sleep context group, an episodic testing context group, a pre-office visit context group, a glucose tolerance context group, an Average Daily Risk Ratio context group, and a predicted HbA1c context group.

9. The device of claim 1, wherein the device further comprises a test strip port formed in the housing for receiving a test strip, wherein the blood glucose measurement comprises the result from a measurement performed on a blood sample provided to a test strip received within the test strip port, the processor being operable to perform said measurement and to store the blood glucose measurement in the memory.

10. The device of claim 1, wherein the device further comprises a data communications port in the housing, wherein the blood glucose measurement comprises a measurement result transferred from a second device and through the communications port, the processor being configured to receive the transferred result and to store the result in the memory as the blood glucose measurement.

11. The device of claim 1, wherein processor is configured to selectively pause and resume the seamless and sequential display of the graphical representations upon user input to the user entry means.

12. A method for displaying blood glucose measurements, comprising:

inputting a blood glucose measurement into a blood glucose management device, wherein the blood glucose management device comprises;

a housing including a display and a user entry means for receiving user input;

a processor in the housing operatively connected to the display and the user entry means; and

a memory connected with the processor;

displaying the blood glucose measurement on the display of the blood glucose management device;

associating via the processor, the blood glucose measurement with at least one other blood glucose measurement stored in the memory of the blood glucose management device to obtain associated blood glucose measurements;

seamlessly displaying a graphical representation of the associated blood glucose measurements on the display of the blood glucose management device for a period of time automatically and without any user interaction with the user entry means of the blood glucose management device after displaying the blood glucose measurement;

associating via the processor, the blood glucose measurement with at least one context group of a plurality of blood glucose measurements stored in the memory of the blood glucose management device; and

seamlessly and sequentially displaying a sequence of a plurality of graphical representations of blood glucose measurements in the at least one context group on the display of the blood glucose management device for a period of time automatically and without any user interaction with the user entry means after displaying the graphical representation of the associated blood glucose measurements.

13. The method of claim 12, further comprising seamlessly displaying a sequence of a plurality of graphical representations of blood glucose measurements in a plurality of context groups of blood glucose measurements stored in the memory of the blood glucose management device each for a period of time automatically and without any user interaction with the user entry means.

14. The method of claim 13, wherein the context groups are segregated based on a time of day of the blood glucose measurements associated therewith.

15. The method of claim 12, further comprising assigning and displaying at least two functions to user entry means of the blood glucose management device while seamlessly displaying the graphical representation of the associated blood glucose measurements.

16. The method of claim 15, wherein one of the at least two functions provides an input to seamlessly display advice regarding the associated blood glucose measurements and the other of the at least two functions provides an input to seamlessly display a second graphical representation of the blood glucose measurement with an associated context group that includes a plurality of blood glucose measurements over time stored in the blood glucose management device.

17. The method of claim 16, wherein the advice includes at least one of an interpretation of the blood glucose measurements relative to pre-defined blood glucose limits and a recommended dietary change.

18. The method of claim 12, further comprising the steps of:

storing a plurality of blood glucose measurements in the memory of the blood glucose management device;

associating each of the plurality of blood glucose measurements with at least one of a number of context groups stored in the memory of the blood glucose management device; and

seamlessly displaying on the blood glucose management device a sequence of at least one graphical representation of each of the number of context groups with its associated blood glucose measurements each for a period of time automatically and without any user interaction with the user entry means after a current graphical representation is displayed for a period of time.

19. The method of claim 18, wherein seamlessly displaying the sequence of at least one graphical representation of each context group can be paused by pressing a button on the blood glucose management device.
