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 an alarm to indicate status of the infusion pump; and

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

wherein the control system includes an alarm profile function for programming a variable alarm volume of the alarm.

2. The system of claim 1, wherein the alarm profile function varies the variable alarm volume according to a schedule.

3. The system of claim 1, wherein the variable alarm volume is set by a user.

4. The system of claim 1, wherein the alarm signals a user to reconnect the infusion pump to the user after the infusion pump has been disconnected from the user for a specified time period.

5. The system of claim 4, wherein the alarm is deactivated when the user reactivates the infusion pump.

6. The system of claim 1, wherein the alarm signals to a user when operation of the infusion pump is suspended.

7. The system of claim 1, wherein the alarm is an audible sound provided by a speaker in the system, a visible signal shown on the system, vibration of the system, or a combination thereof simultaneously.

8. The system of claim 1, wherein the alarm starts out at a low level volume and increases in volume until a user deactivates the alarm.

9. The system of claim 7, wherein the visible signal is a light color change, flashing light, symbol, textual message, or special font style shown in a display on the system.

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

controlling medication delivery by an infusion pump with a control system wherein the infusion pump includes an alarm to indicate status of the infusion pump; and

activating the alarm according to an alarm profile function when a potentially harmful condition occurs in controlling medication delivery, wherein the alarm profile function includes programming a variable alarm volume of the alarm.

11. The method of claim 10, wherein the alarm profile function varies the variable alarm volume according to a schedule.

12. The method of claim 10, wherein the variable alarm volume is set by a user.

13. The method of claim 10, wherein the alarm signals a user to reconnect the infusion pump to the user after the infusion pump has been disconnected from the user for a specified time period.

14. The method of claim 13, wherein the alarm is deactivated when the user reactivates the infusion pump.

15. The method of claim 10, wherein the alarm signals to a user when operation of the infusion pump is suspended.

16. The method of claim 10, wherein the alarm is an audible sound provided by a speaker in the system, a visible signal shown on the system, vibration of the system, or a combination thereof simultaneously.

17. The method of claim 10, wherein the alarm starts out at a low level volume and increases in volume until a user deactivates the alarm.

18. The method of claim 16, wherein the visible signal is a light color change, flashing light, symbol, textual message, or special font style shown in a display on the system.

19. The method of claim 10, wherein the potentially harmful condition is a low pump reservoir condition, low battery voltage, excessive bolus request, pump or system malfunction, or occlusion of the pump outlet.

20. A system for delivering medication, comprising:

an infusion pump including an alarm to indicate status of the infusion pump, wherein the alarm is an audible sound provided by a speaker in the system, a visible signal shown on the system, vibration of the system, or a combination thereof simultaneously; and

a control system for controlling medication delivery by the infusion pump, wherein the control system includes an alarm profile function for programming a variable alarm according to a schedule or an occurrence of a potentially harmful condition.
