Abstract

An apparatus comprising a pump configured to deliver insulin, an input configured to receive blood glucose data, a user interface, and a controller communicatively coupled to the pump, the input, and the user interface. The controller includes a blood glucose data module to compare the blood glucose data to a target blood glucose level for an insulin pump user. The controller is configured to present a question related to the blood glucose level via the user interface when the blood glucose level is different than the target blood glucose level, receive a response to the question via the user interface, and present a recommended user action based at least in part on the response. Other devices, systems, and methods are disclosed.

Claims

1. A method comprising:

receiving blood glucose data into a device that includes an insulin pump;

presenting a question related to a blood glucose level of an insulin pump user when determining, from the blood glucose data, that the blood glucose level is different from a target blood glucose level;

receiving a response to the question into the insulin pump device; and

presenting a recommended action for the user to take based, at least in part, on the response.

2. The method of claim 1, including applying a rule stored in the device to the blood glucose data to determine the question.

3. The method of claim 1, including applying the rule to the blood glucose data to determine the recommended action.

4. The method of claim 2, including:

receiving physiologic data into the device from a second device;

wherein the applying a rule includes applying the rule to the physiologic data to determine the question; and

wherein the displaying a recommended action includes displaying the recommended action based at least in part on the physiologic data.

5. The method of claim 2, including:

receiving user demographic data into the device;

wherein the applying a rule includes applying the rule to the demographic data to determine the question; and

wherein the presenting a recommended action includes adjusting presentation of the recommended action according to the demographic data.

6. The method of claim 2, including:

receiving user lifestyle data into the device;

wherein the applying a rule includes applying the rule to the lifestyle data to determine the question; and

wherein the presenting a recommended action includes displaying a recommended action based at least in part on the lifestyle data.

7. The method of claim 2, including:

determining a rate of change of a blood glucose level of the user from the blood glucose data; and

applying the rule to the rate of change of a blood glucose level to determine at least one of the question and the recommended action.

8. The method of claim 2, including receiving the rule into the device via a device communication port from a second separate device.

9. The method of claim 2, including receiving the rule into the device via the user interface.

10. The method of claim 2, including:

storing insulin delivery history data of the pump user in the insulin pump device; and

applying the rule to the blood glucose data and the insulin delivery history data to determine at least one of the question and the recommended action.

11. The method of claim 1, wherein the presenting a recommended action includes displaying a recommended change to at least one aspect of user lifestyle.

12. The method of claim 1, wherein the presenting a recommended action includes presenting a recommendation for troubleshooting at least one of the insulin pump device, an insulin cartridge, an infusion set, infusion set tubing, an insulin basal rate pattern, and the infusion site.

13. The method of claim 1, wherein the presenting a recommended action includes presenting a recommendation to change at least one of an insulin cartridge, an infusion set, an insulin type, an insulin bolus pattern, and an insulin pump executable program.

14. The method of claim 1, wherein the presenting a recommended action includes presenting a recommendation to initiate a correction bolus from the insulin pump device when the blood glucose level is at risk of being high.

15. The method of claim 1, wherein the presenting a recommended action includes presenting a recommendation to initiate a blood glucose measurement.

16. The method of claim 1, wherein the presenting a recommended action includes presenting a recommendation to perform at least one of a basal rate test, a carbohydrate ratio test, and a correction factor test.

17. The method of claim 1, wherein the presenting a recommended action includes presenting a recommendation to consume carbohydrates when the blood glucose level is at risk of being low.

18. The method of claim 17, including:

storing a database of food options in association with a known amount of carbohydrates; and

wherein presenting a recommendation to consume carbohydrates includes presenting a food option included in the database.

19. The method of claim 1, wherein the presenting a recommended action includes presenting a recommendation to contact a physician.

20. The method of claim 1, including:

presenting a question after receiving an indication into the device that the recommended action was taken; and

presenting a further recommended action for the user to take based, at least in part, on the response to the question presented after the indication was received.

21. The method of claim 1, including:

storing blood glucose history data of the user in the insulin pump device; and

applying the rule to the blood glucose history data and the blood glucose data received from the blood glucose monitor to determine the recommended action.

22. The method of claim 21, including presenting a prompt to the pump user to download blood glucose history data from a separate second device to the insulin pump device.

23. The method of claim 1, wherein receiving blood glucose data includes automatically receiving the blood glucose data from a blood glucose monitor included in the insulin pump device.

24. The method of claim 1, wherein receiving blood glucose data includes:

obtaining the blood glucose data using a second device separate from the insulin pump device; and

receiving the blood glucose data into the insulin pump device from the second device through a communication port.

25. The method of claim 24, wherein receiving blood glucose data includes wirelessly receiving the blood glucose data into the insulin pump device from the second device through a wireless communication port.

26. The method of claim 24, wherein receiving blood glucose data includes receiving the blood glucose data into the insulin pump device in real time as the blood glucose data is obtained by the second device.

27. The method of claim 24, wherein receiving blood glucose data includes recurrently displaying a prompt to a user of the insulin pump device to obtain blood glucose data using the second device.

28. The method of claim 1, wherein receiving blood glucose data includes receiving the blood glucose data through a user interface of the insulin pump device configured for manual entry of blood glucose data.

29. The method of claim 1, including activating an audible alarm if it is determined that the blood glucose level of the pump user is different from the target blood glucose level.

30. The method of claim 1, including presenting a recommended action for the user to take that is related to maintaining normoglycemia when determining, from the blood glucose data, that the blood glucose level is near the target blood glucose level.
