Abstract

A method and apparatus are provided for providing a forgotten bolus warning for an insulin pump user. User selections for mealtimes are received and stored. A user selection for a warning wait period is received and stored. When a time past a mealtime plus the user selection for the warning wait period is identified, checking for a bolus having been taken is performed. Responsive to no bolus having been taken, the user is alerted with the forgotten bolus warning. The user is alerted with the forgotten bolus warning by an audible, visual, or tactile warning for a programmable period of time. The user selections for mealtimes are received and stored on a daily basis for each day of the week. The user selection for a warning wait period can be received and stored independently for each meal.

Claims

1. A method for providing a forgotten bolus warning for an insulin pump user, an insulin pump for performing the method comprising the steps of:

receiving and storing by the insulin pump user selections for mealtimes;

receiving and storing by the insulin pump a user selection for a warning wait period;

identifying by the insulin pump a time past a mealtime plus said user selection for said warning wait period;

responsive to said identified time, checking by the insulin pump for a bolus having been taken; and

responsive to detecting by the insulin pump no bolus having been taken, alerting the user with the forgotten bolus warning.

2. A method for providing a forgotten bolus warning for an insulin pump user as recited in claim 1 wherein the step of receiving and storing by the insulin pump user selections for mealtimes includes the steps of prompting for a day of the week and storing a day of the week;

responsive to said stored day of the week, prompting for a mealtime and storing a mealtime;

checking for a next mealtime; and

responsive to an identified next mealtime, prompting for a mealtime and storing a mealtime.

3. A method for providing a forgotten bolus warning for an insulin pump user as recited in claim 2 includes the steps of sequentially repeating the steps of prompting for a day of the week and storing a day of the week;

responsive to said stored day of the week, prompting for a mealtime and storing a mealtime;

checking for a next mealtime; and

responsive to an identified next mealtime, prompting for a mealtime and storing a mealtime for each day of the week.

4. A method for providing a forgotten bolus warning for an insulin pump user as recited in claim 2 wherein the step of receiving and storing by the insulin pump a user selection for a warning wait period includes the step of storing a user selection for said warning wait period with each stored mealtime.

5. A method for providing a forgotten bolus warning for an insulin pump user as recited in claim 1 wherein the step responsive to detecting by the insulin pump no bolus having been taken, of alerting the user with the forgotten bolus warning includes the step of alerting the user with an audible forgotten bolus warning for a programmable period of time.

6. A method for providing a forgotten bolus warning for an insulin pump user as recited in claim 1 wherein the step responsive to detecting by the insulin pump no bolus having been taken, of alerting the user with the forgotten bolus warning includes the step of alerting the user with a visual forgotten bolus warning for a programmable period of time.

7. A method for providing a forgotten bolus warning for an insulin pump user as recited in claim 1 wherein the step responsive to detecting by the insulin pump no bolus having been taken, of alerting the user with the forgotten bolus warning includes the step of alerting the user with a tactile forgotten bolus warning for a programmable period of time.

8. A method for providing a forgotten bolus warning for an insulin pump user as recited in claim 1 wherein the step responsive to detecting by the insulin pump no bolus having been taken, of alerting the user with the forgotten bolus warning includes the step of providing an audible, visual, or tactile warning until reset by the user.

9. An insulin pump for providing a forgotten bolus warning for an insulin pump user, said insulin pump comprising:

an insulin pump processor;

a display coupled to said insulin pump processor for prompting the user for user selections;

a keypad coupled to said insulin pump processor for receiving and storing user selections for mealtimes and for a warning wait period;

said insulin pump processor for identifying a time past a mealtime plus said user selection for said warning wait period and for checking for a bolus having been taken; and

said insulin pump processor responsive to detecting no bolus having been taken, for alerting the user with the forgotten bolus warning.

10. An insulin pump for providing a forgotten bolus warning for an insulin pump user as recited in claim 9 includes an alarm coupled to said insulin pump processor;

said alarm for providing the forgotten bolus warning.

11. An insulin pump for providing a forgotten bolus warning for an insulin pump user as recited in claim 10 wherein said alarm alerts the user with an audible, visual or tactile warning for a programmable amount of time.

12. An insulin pump for providing a forgotten bolus warning for an insulin pump user as recited in claim 10 wherein said alarm alerts the user with an audible, visual or tactile warning until reset by the user.

13. A computer program product providing a forgotten bolus warning for a user of an insulin pump including an insulin pump processor unit, said computer program product including a plurality of computer executable instructions stored on a computer readable medium, wherein said instructions, when executed by said processor unit, cause the insulin pump processor unit to perform the steps of:

receiving and storing by the insulin pump processor unit user selections for mealtimes and for a warning wait period;

identifying by the insulin pump processor unit a time past a mealtime plus said user selection for said warning wait period;

responsive to said identified time, checking by the insulin pump processor unit for a bolus having been taken; and

responsive to detecting by the insulin pump processor unit no bolus having been taken, alerting the user with the forgotten bolus warning.

14. A computer program product providing a forgotten bolus warning for a user of an insulin pump as recited in claim 13 wherein said instructions, when executed by said processor unit, cause the insulin pump processor unit to perform the steps of:

prompting the user for entering said user selections for mealtimes and for a warning wait period.

15. A computer program product providing a forgotten bolus warning for a user of an insulin pump as recited in claim 13 wherein the step of alerting the user with the forgotten bolus warning includes the step of providing an audible, visual, or tactile warning until reset by the user.

16. A computer program product providing a forgotten bolus warning for a user of an insulin pump as recited in claim 13 wherein the step of alerting the user with the forgotten bolus warning includes the step of providing an audible, visual, or tactile warning for a programmable period of time.
