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 data storage unit for storing data including meal event information;

a strip port configured to receive an analyte test strip; and

a controller unit 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 a meal event, the controller unit is further configured to automatically select a bolus determination mode to determine a bolus dosage.

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

3. The apparatus of claim 2, wherein the output unit is configured to provide one or more of a visual output, an audible output, a tactile output, or one or more combinations thereof.

4. 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.

5. The apparatus of claim 1, further including an input unit operatively coupled to the controller unit, wherein the controller unit is configured to determine the bolus dosage in response to a command received from the input unit.

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

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 operatively coupled to the controller unit, the data communication unit configured for one of uni-directional data communication or bi-directional data communication, wherein the data communication unit is configured to receive one or more signals associated with a monitored analyte level.

9. The apparatus of claim 8, wherein the data communication unit is configured to receive the one or more signals associated with the 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 and a mediator, wherein at least one of the analyte-responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and further wherein at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.

11. A method, comprising:

storing data including meal event information;

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

automatically selecting a 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 a meal event.

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 a command from an input unit, wherein the bolus dosage is determined in response to the received command.

16. The method of claim 11, further including determining an analyte level from an analyte test strip sample.

17. The method of claim 16, wherein the determined analyte level includes one or more of a glucose level or a ketone level.

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

19. The method of claim 18, wherein the analyte sensor includes at least one working electrode including an analyte-responsive enzyme and a mediator, wherein at least one of the analyte-responsive enzyme and the mediator is chemically bonded to a polymer disposed on the working electrode, and further wherein at least one of the analyte-responsive enzyme and the mediator is crosslinked with the polymer.
