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 including a dual wave bolus delivery function; and

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

wherein the control system includes a simplified menu for controlling the dual wave bolus delivery function,

wherein the simplified menu includes entry of a total medication volume, the entry being divided by a preset ratio into a first wave bolus and a second wave bolus that forms the dual wave bolus,

wherein the first wave bolus is delivered before the second wave bolus; and

wherein the control system further includes a conventional menu for controlling the dual wave bolus delivery function and the simplified menu and the conventional menu are alternately selected.

2. The system of claim 1, wherein the first wave bolus and the second wave bolus are delivered with a preset delay time between the first wave bolus and the second wave bolus.

3. The system of claim 2, 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 2, wherein the preset delay time is 1½

hours.

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

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

providing a simplified menu for controlling the dual wave bolus delivery function,

wherein the simplified menu includes entry of a total medication volume, the entry being divided by a preset ratio into a first wave bolus and a second wave bolus that forms the dual wave bolus,

wherein the first wave bolus is delivered before the second wave bolus; and

wherein the control system further includes a conventional menu for controlling the dual wave bolus delivery function and further includes the step of alternately selecting between the simplified menu and the conventional menu.

8. The method of claim 7, wherein the first wave bolus and the second wave bolus are delivered with a preset delay time between the first wave bolus and the second wave bolus.

9. The method of claim 8, wherein the preset ratio and preset delay time are default values set in a pump setup menu.

10. The method of claim 9, 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.

11. The method of claim 10, wherein the additional delivery functions include a square wave bolus delivery function and basal delivery function.

12. The method of claim 8, wherein the preset delay time is 1½

hours.

13. A medical device for delivering fluid to a patient, the medical device comprising:

a control system to control fluid delivery from the medical device; and

a bolus delivery feature coupled to the control system to allow the patient to deliver a bolus of fluid with the medical device,

wherein the control system divides the bolus by a predefined ratio to create an immediate portion of the bolus and a delayed portion of the bolus,

wherein the immediate portion of the bolus is delivered immediately after the patient uses the bolus delivery feature to deliver the bolus,

wherein the delayed portion of the bolus is delivered after the immediate portion of the bolus is delivered.

14. The medical device according to claim 13, wherein the bolus is a dual wave bolus.

15. The medical device according to claim 13, wherein the predefined ratio is a default value.

16. The medical device according to claim 13, wherein the predefined ratio is adjustable by the user.

17. The medical device according to claim 13, wherein the immediate portion of the bolus and the delayed portion of the bolus are delivered with a predefined delay time between the immediate portion of the bolus and the delayed portion of the bolus.

18. The medical device according to claim 17, wherein the predefined delay time is a default value.

19. The medical device according to claim 17, wherein the predefined delay time is adjustable by the user.

20. The medical device according to claim 17, wherein the predefined delay time is 1½

hours.

21. The medical device according to claim 13, wherein the medical device includes one or more additional delivery functions.

22. The medical device according to claim 13, wherein the additional delivery functions include a square wave bolus delivery function and basal delivery function.
