Abstract

Method and apparatus for performing a discrete glucose testing and bolus dosage determination including a glucose meter with bolus calculation function are provided.

Claims

1. An apparatus including a glucose meter, comprising:

a housing having a display unit disposed thereon;

a data storage unit disposed within the housing, the data storage unit storing meal event information;

a strip port coupled to the housing and configured to receive a test strip therein; and

a controller unit coupled to the housing, the controller configured to process one or more signals associated with data received from the test strip, and to provide an output to the display unit based on the processed one or more signals, after providing the output based on the processed one or more signals, the controller further configured to generate and output to the display unit a query to a user as to whether to determine an insulin bolus dosage and, when a user selection to determine an insulin bolus dosage is detected, entering a bolus dosage determination mode, and when a user selection to not determine an insulin bolus dosage is detected, storing the processed one or more signals;

wherein when the bolus dosage determination mode is entered, the controller unit is further configured to output to the display unit a list of programmed bolus dosage determination options, and in response to a user selection of one of the programmed bolus dosage determination options from the list of programmed bolus dosage determination options, executing the selected one of the programmed bolus dosage determination options; and

wherein when the test strip is received within a predetermined time period of a meal event, a carbohydrate bolus determination mode is automatically selected.

2. The apparatus of claim 1, wherein the controller unit is further configured to display on the display unit the bolus dosage determined based on the execution of the selected one of the programmed bolus dosage determination options.

3. The apparatus of claim 2 wherein the displayed bolus dosage is one or more of an alphanumeric display, a graphical display, a video display, an audio display, a vibratory output, or combinations thereof.

4. The apparatus of claim 1 further including an output unit configured to provide one or more of an audible notification, a vibratory notification, or combinations thereof.

5. The apparatus of claim 1 wherein the list of programmed bolus dosage determination options includes one or more of a carbohydrate bolus, a correction bolus, an extended bolus, a dual bolus, or combinations thereof.

6. The apparatus of claim 1 further including an input unit coupled to the housing to receive the user selection to determine the insulin bolus dosage or the user selection to not determine the insulin bolus dosage.

7. The apparatus of claim 6 wherein the input unit includes one or more of an input button, a touch sensitive screen, a jog wheel, or combinations thereof.

8. The apparatus of claim 1 wherein the data received from the test strip corresponds to an analyte level.

9. The apparatus of claim 8 wherein the analyte level includes a glucose level of a patient.

10. The apparatus of claim 1 wherein the predetermined time period is within one hour prior to a meal event.

11. The apparatus of claim 1 wherein the data storage unit stores the user'"'"'s insulin sensitivity information, and wherein the bolus dosage is determined based at least in part on the user'"'"'s insulin sensitivity information.

12. The apparatus of claim 1 wherein the apparatus is configured to alert the user if a predetermined bolus time period has not passed since a previous bolus administration.

13. A computer program product for use with a glucose meter, the program product comprising a computer readable storage medium having a computer program stored thereon which controls the meter to process one or more signals associated with data received from a test strip, to store meal event information, to display a query to a user as to whether to calculate an insulin bolus dosage and, when a user selection to determine an insulin bolus dosage is detected, to instruct the meter to enter a bolus dosage determination mode, and when a user selection to not determine an insulin bolus dosage is detected, to instruct the meter to store the processed one or more signals, wherein when the bolus dosage determination mode is entered, the computer program further controls the meter to output a list of programmed bolus dosage determination options, and in response to a user selection of one of the programmed bolus dosage determination options from the list of programmed bolus dosage determination options, to execute the selected one of the programmed bolus dosage determination options, wherein when the test strip is received within a predetermined time period of a meal event, the computer program instructs the glucose meter to automatically select a carbohydrate bolus determination mode.

14. The computer program product of claim 13 wherein the computer program instructs the glucose meter to display the bolus dosage determined based on the execution of the selected one of the programmed bolus dosage determination options.

16. The computer program product of claim 13 wherein the list of programmed bolus dosage determination options includes one or more of a carbohydrate bolus, a correction bolus, an extended bolus, a dual bolus, or combinations thereof.

15. The computer program product 14 wherein the bolus dosage displayed on the glucose meter is one or more of an alphanumeric display, a graphical display, a video display, an audio display, a vibratory output, or combinations thereof.

17. A method, comprising:

storing meal event information;

receiving an analyte sample;

determining an analyte level corresponding to the analyte sample;

displaying the determined analyte level on a display unit;

generating and outputting on the display unit a query to a user as to whether to determine a bolus dosage; and

when a user selection to determine a bolus dosage is detected, entering a bolus dosage determination mode, and when a user selection to not determine a bolus dosage is detected, storing the analyte level, wherein when the bolus dosage determination mode is entered, outputting to the display unit a list of programmed bolus dosage determination options, and in response to a user selection of one of the programmed bolus dosage determination options from the list of programmed bolus dosage determination options, executing the selected one of the programmed bolus dosage determination options, and when the analyte sample is received within a predetermined time period of a meal event, automatically selecting a carbohydrate bolus determination mode.

18. The method of claim 17 further including displaying the bolus dosage determined based on the execution of the selected one of the programmed bolus dosage determination options.

19. The method of claim 17 further including generating one or more of an audible notification, a vibratory notification, a visual notification, or combinations thereof, associated with one or more of the determined bolus dosage based on the execution of the selected one of the programmed bolus dosage determination options, the determined analyte level, or combinations thereof.

20. The method of claim 17 wherein the list of programmed bolus dosage determination options includes one or more of a carbohydrate bolus, a correction bolus, an extended bolus, a dual bolus, or combinations thereof.

21. The method of claim 17 wherein the analyte level includes a measured glucose level of a patient and the bolus dosage is an insulin bolus dosage.

22. The method of claim 17 wherein outputting on the display unit the query to the user comprises displaying a prompt on the display unit.

23. The method of claim 22 further comprising prompting a user to provide an estimate of a carbohydrate amount to be ingested.

24. The method of claim 22 further comprising prompting a user to provide a time duration information for the determined bolus dosage.

25. The method of claim 17 wherein determining the bolus dosage is further based on a time difference between the determining the glucose level and a predetermined time period of a meal event.

26. The method of claim 17 wherein the analyte level is a glucose level and the bolus dosage is an insulin bolus dosage.
