Abstract

Systems and methods for the delivery and monitoring of a medication, such as insulin, to a recipient are provided. An exemplary feature-rich system comprises an infusion pump with a control system for controlling medication delivery by the infusion pump and a bolus estimator for estimating an appropriate amount of medication for delivery by the control system with the infusion pump. Estimating the appropriate amount of medication for delivery is based upon one or more settings which each vary according to a setting profile. In other embodiments, the control system comprises a suspend function for temporarily suspending medication delivery by the infusion pump, an alarm profile function for programming a variable alarm volume of the alarm and a simplified menu for controlling the dual wave bolus delivery function.

Claims

1. A system for delivering medication, comprising:

an infusion pump;

a control system for controlling medication delivery by the infusion pump; and

a bolus estimator for estimating an appropriate amount of medication for delivery by the control system with the infusion pump, wherein;

estimating the appropriate amount of medication for delivery is based upon one or more settings that include insulin sensitivity and vary according to one or more setting profiles that can be set by a user to vary according to a daily schedule;

the control system controls medication delivery according to one or more medication delivery profiles comprising the appropriate amount of medication estimated by the bolus estimator; and

the setting profile is entered with a graphical programming interface that includes a series of discrete divisions, each having a setting value and the setting profile is programmed by adjusting the setting value of selected ones of the discrete divisions in sequence such that any setting value of each prior discrete division is unchanged and any setting value of each subsequent discrete division is automatically adjusted to the value the selected ones of the discrete divisions.

2. The system of claim 1, wherein the insulin sensitivity setting can be set to vary according to a plurality of separate setting profiles that are stored in a memory of the system.

3. The system of claim 1, wherein the control system includes a suspend function for temporarily suspending medication delivery by the infusion pump.

4. The system of claim 1, wherein the one or more settings further include target blood glucose or carbohydrate ratio.

5. The system of claim 4, wherein the setting profile for at least one of the one or more settings includes a value which varies according to a schedule.

6. The system of claim 1, wherein the control system is programmed to control medication delivery from a source selected from the group including an RF programmer, a communication station and direct input.

7. The system of claim 1, wherein the bolus estimator estimates the appropriate amount of medication based upon one or more event markers stored in a memory of the system.

8. The system of claim 7, wherein the one or more event markers track events which affect medication need.

9. The system of claim 7, wherein the one or more event markers are selected from the group comprising a meal marker, a snack marker, a high blood glucose marker, a low blood glucose marker, an exercise marker, an illness marker and a stress marker.

10. A method of delivering medication, comprising the steps of:

controlling medication delivery by an infusion pump with a control system;

estimating an appropriate amount of medication for delivery by the control system with the infusion pump, wherein;

estimating the appropriate amount of medication for delivery is based upon one or more settings that include insulin sensitivity and vary according to one or more setting profiles that can be set by a user to vary according to a daily schedule;

the control system delivers medication delivery according to one or more medication delivery profiles comprising the appropriate amount of medication estimated by the bolus estimator; and

the setting profile is entered with a graphical programming interface that includes a series of discrete divisions, each having a setting value and the setting profile is programmed by adjusting the setting value of selected ones of the discrete divisions in sequence such that any setting value of each prior discrete division is unchanged and any setting value of each subsequent discrete division is automatically adjusted to the value the selected ones of the discrete divisions.

11. The method of claim 10, wherein the insulin sensitivity setting can be set to vary according to a plurality of separate setting profiles that are stored in a memory of the system.

12. The method of claim 11, wherein the one or more medication delivery profiles includes the appropriate amount of medication estimated by the bolus estimator.

13. The method of claim 10, wherein the one or more settings further include target blood glucose or carbohydrate ratio.

14. The method of claim 13, wherein the setting profile for at least one of the one or more settings includes a value which varies according to a schedule.

15. The method of claim 10, wherein the control system is programmed to control medication delivery from a source selected from the group including an RF programmer, a communication station and direct input.

16. The method of claim 10, wherein the bolus estimator estimates the appropriate amount of medication based upon one or more event markers stored in a memory of the system.

17. The method of claim 16, wherein the one or more event markers track events which affect medication need.

18. The method of claim 16, wherein the one or more event markers are selected from the group comprising a meal marker, a snack marker, a high blood glucose marker, a low blood glucose marker, an exercise marker, an illness marker and a stress marker.
