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, comprising:

a housing including a strip port;

a data storage unit disposed in the housing comprising data that comprises a time at which a meal event occurs; and

a controller unit disposed in the housing that is configured to detect when the analyte test strip is received in the strip port;

wherein when the controller unit determines that the analyte test strip is received in the strip port within a predetermined time period of when the meal event occurs, the controller unit is further configured to automatically select a correction bolus determination mode to determine a bolus dosage.

2. The apparatus of claim 1, further including an output unit coupled to the housing, wherein the controller unit is further configured to output the determined bolus dosage on the output unit.

3. The apparatus of claim 1, wherein the determined bolus dosage includes one or more of a carbohydrate bolus, a correction bolus, an extended bolus, a dual bolus, or one or more combinations thereof.

4. The apparatus of claim 1, further including an input unit coupled to the housing, wherein the controller unit is configured to receive one or more inputs from the input unit.

5. The apparatus of claim 4, wherein the one or more inputs include insulin sensitivity information, amount of carbohydrate to be ingested, or a type of bolus dosage.

6. The apparatus of claim 1, wherein the controller unit is further configured to determine an analyte level from an analyte sample on the analyte test strip received in the strip port.

7. The apparatus of claim 6, wherein the determined analyte level includes one or more of a glucose level or a ketone level.

8. The apparatus of claim 1, further including a data communication unit disposed in the housing and configured for one of uni-directional data communication or bi-directional data communication.

9. The apparatus of claim 8, wherein the data communication unit is configured to receive one or more signals associated with a monitored analyte level from an analyte sensor.

10. The apparatus of claim 9, wherein the analyte sensor includes at least one working electrode including an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.

11. A method, comprising:

storing data that comprises a time at which a meal event occurs;

detecting when an analyte test strip is received in a strip port; and

automatically selecting a correction bolus determination mode to determine a bolus dosage when it is detected that the analyte test strip is received in the strip port within a predetermined time period of when the meal event occurs.

12. The method of claim 11, further including outputting the determined bolus dosage on an output unit.

13. The method of claim 12, further including outputting one or more of a visual output, an audible output, a tactile output, or one or more combinations thereof.

14. The method of claim 11, wherein the determined bolus dosage includes one or more of a carbohydrate bolus, a correction bolus, an extended bolus, a dual bolus, or one or more combinations thereof.

15. The method of claim 11, further including receiving one or more inputs from a user.

16. The method of claim 15, wherein the one or more inputs include insulin sensitivity information, amount of carbohydrate to be ingested, or a type of bolus dosage.

17. The method of claim 11, further including determining an analyte level from an analyte sample on the analyte test strip received in the strip port.

18. The method of claim 17, wherein the determined analyte level includes one or more of a glucose level or a ketone level.

19. The method of claim 11, further including receiving one or more signals associated with a monitored analyte level from an analyte sensor.

20. The method of claim 19, wherein the analyte sensor includes at least one working electrode including an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.
