Abstract

Claims (23)

1. An ambulatory infusion pump system comprising:

a reservoir configured to contain insulin;

a delivery mechanism configured to deliver insulin from the reservoir to a user; and

at least one processor configured to:

determine that a user will be eating a meal; and

cause the delivery mechanism to deliver a meal bolus of insulin of a single fixed amount to the user in a single continuous delivery operation in response to determining that the user will be eating the meal, wherein the single fixed amount of the meal bolus is predetermined without precisely matching the amount of the meal bolus with a number of carbohydrates to be consumed in the meal.

2. The system of claim 1 , wherein the single fixed amount of insulin is a predetermined number of units of insulin.

3. The system of claim 2 , further comprising a memory and wherein the predetermined number of units of insulin is saved into memory.

4. The system of claim 1 , wherein the processor is configured to determine that a user will be eating a meal based on user input entered by the user.

5. The system of claim 1 , where the processor is configured to automatically deliver the meal bolus of insulin after determining that the user will be eating a meal.

6. The system of claim 1 , wherein the processor is further configured to receive a user confirmation of the meal bolus of insulin prior to delivering the meal bolus.

7. The system of claim 1 , wherein the processor is further configured to receive a modification to the single fixed amount.

8. The system of claim 1 , wherein the single fixed amount of insulin can vary based on a type of meal.

9. The system of claim 8 , wherein the type of meal can include breakfast, lunch and dinner.

10. A method of providing insulin therapy to a user of an ambulatory infusion pump, the ambulatory infusion pump being part of an ambulatory infusion pump system, comprising:

determining with a processor of the ambulatory infusion pump system that a user will be eating a meal; and

causing, with the processor, the ambulatory infusion pump to deliver a meal bolus of insulin of a single fixed amount to the user in a single continuous delivery operation in response to determining with the processor of the ambulatory infusion pump system that the user will be eating the meal, wherein the single fixed amount of the meal bolus is predetermined without precisely matching the amount of the meal bolus with a number of carbohydrates to be consumed in the meal.

11. The method of claim 10 , wherein the single fixed amount of insulin is a predetermined number of units of insulin.

12. The method of claim 11 , further comprising storing the predetermined number of units of insulin in a memory.

13. The method of claim 10 , wherein determining with the processor of the ambulatory infusion pump system that the user will be eating a meal includes receiving user input entered by the user.

14. The method of claim 10 , wherein causing, with the processor, the ambulatory infusion pump to deliver the meal bolus includes automatically delivering the meal bolus of insulin after determining with the processor of the ambulatory infusion pump system that the user will be eating a meal.

15. The method of claim 10 , further comprising receiving a user confirmation of the meal bolus of insulin prior to delivering the meal bolus.

16. The method of claim 10 , further comprising receiving a modification to the single fixed amount.
