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; and

a control system for controlling medication delivery by the infusion pump including a dual wave bolus delivery function;

wherein the control system comprises a first menu for controlling the dual wave bolus delivery function; and

the first menu includes a single entry of a total medication volume, the single entry being divided by a preset ratio into a first wave bolus and a second wave bolus and delivered with a preset delay time between the first wave bolus and the second wave bolus.

2. The system of claim 1, wherein the control system further includes a second menu for controlling the dual wave bolus delivery function and the first menu and the second menu are alternately selected.

3. The system of claim 1, wherein the preset ratio and preset delay time are default values set in a pump setup menu.

4. The system of claim 3, wherein the control system further includes one or more additional delivery functions and a default delivery mode is selected in the pump setup menu from the dual wave bolus delivery function and the one or more additional delivery functions.

5. The system of claim 4, wherein the additional delivery functions include a square wave bolus delivery function and basal delivery function.

6. The system of claim 4, wherein the control system includes an option of selecting one or more delivery functions to suspend at a certain time point.

7. The system of claim 6, wherein the control system includes an option of resuming the selected one or more delivery functions from the time point of suspension.

8. The system of claim 7, wherein upon resuming the selected one or more delivery functions, the control system delivers a compensating bolus to account for an amount of medication missed as a result of the suspension of the one or more delivery functions.

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

controlling medication delivery by an infusion pump with a control system including a dual wave bolus delivery function; and

providing a first menu for controlling the dual wave bolus delivery function;

wherein the first menu includes a single entry of a total medication volume, the single entry being divided by a preset ratio into a first wave bolus and a second wave bolus and delivered with a preset delay time between the first wave bolus and the second wave bolus.

10. The method of claim 9, wherein the control system further includes a second menu for controlling the dual wave bolus delivery function and further includes the step of alternately selecting between the first menu and the second menu.

11. The method of claim 9, wherein the preset ratio and preset delay time are default values set in a pump setup menu.

12. The method of claim 11, wherein the control system further includes one or more additional delivery functions and a default delivery mode is selected in the pump setup menu from the dual wave bolus delivery function and the one or more additional delivery functions.

13. The method of claim 12, wherein the additional delivery functions include a square wave bolus delivery function and basal delivery function.

14. The system of claim 12, wherein the control system includes an option of selecting one or more delivery functions to suspend at a certain time point.

15. The system of claim 14, wherein the control system includes an option of resuming the selected one or more delivery functions from the time point of suspension.

16. The system of claim 15, wherein upon resuming the selected one or more delivery functions, the control system delivers a compensating bolus to account for an amount of medication missed as a result of the suspension of the one or more delivery functions.

17. A system for delivering medication, comprising:

an infusion pump; and

a control system for controlling medication delivery by the infusion pump including a dual wave bolus delivery function and one or more additional delivery functions;

wherein the control system includes an option of selecting one or more delivery functions to suspend or resume at a certain time point and wherein the control system delivers a compensating bolus to account for an amount of medication missed as a result of suspending the one or more delivery functions; and

the option includes a single entry of a total medication volume, the single entry being divided by a preset ratio into a first wave bolus and a second wave bolus and delivered with a preset delay time between the first wave bolus and the second wave bolus.

18. The system of claim 17, wherein the additional delivery functions include a square wave bolus delivery function and basal delivery function.
