Abstract

An infusion system with an adaptive user interface is disclosed. The infusion system is interactive with the user and adaptive to the user'"'"'s needs, incrementally guiding the user to enter information or perform a desired or necessary action in the infusion system. As a result, the user is not required to remember how to navigate through a series of menu structures to enter the information or perform the action.

Claims

1. In an infusion system including an external infusion device, a sensor, and a transmitter for transmitting a sensor signal from the sensor to the external infusion device, a method for guiding action by a user when the external infusion device fails to receive the sensor signal from the sensor, the method comprising:

displaying an alarm indicating that the infusion device has failed to receive the sensor signal from the sensor for a period of time;

determining a cause of the failure to receive the sensor signal from the sensor; and

directing the user to perform at least one corrective action associated with the failure to receive the sensor signal from the sensor by providing the user with one or more outputs to which the user is to respond with a respective user input or action, wherein each successive one of the outputs is responsive to a previous user input or action.

2. The method of claim 1, wherein the alarm indicates that the infusion device has failed to receive the sensor signal from the sensor for a predetermined period of time.

3. The method of claim 1, wherein the alarm indicates that the infusion device has failed to receive the sensor signal from the sensor for a period of time set by the user.

4. The method of claim 1, wherein the cause of the failure to receive the sensor signal from the sensor relates to the sensor being located too far away from the infusion device, and the directing the user to perform at least one corrective action comprises directing the user to move the infusion device closer to the sensors the method further comprising:

determining whether the infusion device is receiving the sensor signal from the sensor; and

informing the user that the failure to receive the sensor signal from the sensor has been corrected if the infusion device is determined to be receiving the sensor signal from the sensor.

5. The method of claim 4, wherein if the infusion device is determined not to be receiving the sensor signal from the sensor, the directing the user to perform at least one corrective action further comprises directing the user to check a connection between the sensor and the transmitter.

6. The method of claim 5, wherein the directing the user to perform at least one corrective action further comprises directing the user to replace the sensor if the failure to receive the sensor signal from the sensor has not been corrected after directing the user to check the connection between the sensor and the transmitter.

7. In an infusion system including an external infusion device and a sensor, a method for guiding action by a user when the sensor requires the user to perform a calibration, the method comprising:

displaying a notification when the sensor requires a calibration to be performed by the user; and

directing the user to perform the calibration by providing the user with one or more outputs to which the user is to respond with a respective user input or action, wherein each successive one of the outputs is responsive to a previous user input or action.

8. The method of claim 7, wherein the directing the user to perform the calibration further comprises instructing the user to obtain a calibration reference value for the sensor and guiding the user to enter the calibration reference value into the infusion device to calibrate the sensor.

9. In an infusion system including an external infusion device for delivering medication to a user and a sensor for measuring glucose levels in the user, a method for guiding action by the user when a glucose level is above a maximum or below a minimum boundary, the method comprising:

displaying an alarm when a glucose level of the user is above a maximum or below a minimum boundary; and

directing the user to perform at least one corrective action associated with the alarm by providing the user with one or more outputs to which the user is to respond with a respective user input or action, wherein each successive one of the outputs is responsive to a previous user input or action.

10. The method of claim 9, wherein the directing the user to perform at least one corrective action further comprises:

asking the user to adjust settings on the infusion device related to therapy management of the user; and

directing the user to adjust one or more of the settings on the infusion device related to the therapy management of the user.

11. The method of claim 10, wherein the settings on the infusion device related to the therapy management of the user comprise at least one of bolus-related settings and basal-related settings.

12. The method of claim 11, wherein the directing the user to adjust one or more of the settings on the infusion device related to the therapy management of the user comprises at least one of programming a temporary basal rate, modifying a basal rate pattern, programming a meal bolus, and programming a correction bolus.

13. The method of claim 10, further comprising:

suspending delivery of the medication to the user when the glucose level of the user is below the minimum boundary; and

resuming delivery of the medication to the user after directing the user to adjust one or more of the settings on the infusion device related to the therapy management of the user.

14. The method of claim 13, wherein the delivery of the medication to the user is suspended automatically when the glucose level of the user is below the minimum boundary.

15. The method of claim 13, wherein the delivery of the medication to the user is suspended based on input from the user.

16. In an infusion system including an external infusion device and a sensor, a method for guiding action by a user when a calibration reference value for the sensor entered by the user triggers a calibration error, the method comprising:

displaying an alarm when the calibration reference value for the sensor entered by the user triggers the calibration error;

determining a cause of the calibration error; and

directing the user to perform at least one corrective action associated with the calibration error by providing the user with one or more outputs to which the user is to respond with a respective user input or action, wherein each successive one of the outputs is responsive to a previous user input or action.

17. The method of claim 16, wherein the determining the cause of the calibration error comprises asking whether glucose levels of the user are stable, and if the glucose levels of the user are not stable, the directing the user to perform at least one corrective action further comprises instructing the user to wait for a period of time, instructing the user to obtain a calibration reference value, and guiding the user to enter the calibration reference value into the infusion device to calibrate the sensor.

18. The method of claim 16, wherein the determining the cause of the calibration error comprises asking whether the calibration reference value for the sensor was correctly entered by the user, and if the calibration reference value for the sensor was not correctly entered, the directing the user to perform at least one corrective action further comprises instructing the user to reenter the calibration reference value into the infusion device to calibrate the sensor.

19. The method of claim 16, wherein the determining the cause of the calibration error comprises asking whether the calibration reference value for the sensor was too old to calibrate the sensor, and if the calibration reference value for the sensor was too old to calibrate the sensor, the directing the user to perform at least one corrective action further comprises instructing the user to obtain a new calibration reference value for the sensor and guiding the user to enter the new calibration reference value into the infusion device to calibrate the sensor.

20. The method of claim 16, wherein the determining the cause of the calibration error comprises asking whether sensor was recently inserted into the user, and if the sensor was recently inserted into the user, the directing the user to perform at least one corrective action further comprises instructing the user to wait for a period of time, instructing the user to obtain a new calibration reference value for the sensor, and guiding the user to enter the new calibration reference value into the infusion device to calibrate the sensor.
