Abstract

Methods and apparatus, including computer program products, are provided for backfilling. In some example embodiments, there is provided a method that includes receiving, at a receiver, backfill data representative of sensor data stored, at a continuous blood glucose sensor and transmitter assembly, due to a loss of a wireless link between the receiver and the continuous blood glucose sensor and transmitter assembly; generating, at the receiver, at least one of a notification or a graphically distinct indicator for presentation at a display of the receiver, the at least one of the notification or the graphically distinct indicator enabling the backfill data to be graphically distinguished, when presented at the display, from non-backfill data; and generating, at the receiver, a view including the backfill data, the non-backfill data, and the generated at least one of the notification or the graphically distinct indicator. Related systems, methods, and articles of manufacture are also described.

Claims

1. A method comprising:

receiving, at a receiver, backfill data representative of sensor data stored, at continuous blood glucose sensor and transmitter assembly, due to a loss of a wireless link between the receiver and the continuous blood glucose sensor and transmitter assembly;

generating, at the receiver, at least one of a notification or a graphically distinct indicator for presentation at a display of the receiver, the at least one of the notification or the graphically distinct indicator enabling the backfill data to be graphically distinguished, when presented at the display, from non-backfill data; and

generating, at the receiver, a view including the backfill data, the non-backfill data, and the generated at least one of the notification or the graphically distinct indicator.

2. The method of claim 1, wherein the graphically distinct indicator comprises a color that is different from another color used to present the non-backfill data.

3. The method of claim 1, wherein the graphically distinct indicator comprises a symbol that is different from another symbol used to present the non-backfill data.

4. The method of claim 3, wherein the symbol comprises at least one of a dashed line, a solid line, a solid polygon, or a hollow polygon.

5. The method of claim 1, wherein the graphically distinct indicator comprises an overlay on the backfill data.

6. The method of claim 1, wherein the notification comprises an indication that the non-backfill data is being presented at the display.

7. The method of claim 1, wherein the notification indicates at least one alert occurring during a time associated with the backfill data.

8. The method of claim 1, wherein the notification indicates a request to display the backfill data associated with a missed alert.

9. The method of claim 1, wherein the notification indicates a request to consent to the display of the backfill data.

10. The method of claim 1, wherein the notification indicates a request to consent to the display of the backfill data and at least one alert occurring during a time associated with the backfill data.

11. The method of claim 1, wherein the notification indicates a request to display backfill data, when an alert is missed.

12. The method of claim 1, wherein the view includes a plot of glucose values formed from the backfill data and the non-backfill data.

13. The method of claim 1, further comprising:

displaying, at the receiver, the view including the backfill data, the non-backfill data, and the generated at least one of the notification or the graphically distinct indicator.

14. The method of claim 1, wherein the backfill data is displayed, when an indication of consent is received.

15. The method of claim 1, further comprising:

inhibiting, at the receiver, the receiving of the backfill data, without an indication of consent.

16. The method of claim 1, wherein the receiving is in response to a request from the receiver.

17. The method of claim 1, further comprising:

classifying, at the receiver, an alert as a missed alert, when the alert occurred during a time associated with the backfill data.

18. The method of claim 1, wherein the backfill data is received as compressed data.

19. The method of claim 18, wherein the compressed data comprises a function representative of at least a portion of a curve corresponding to the backfill data.

20. The method of claim 19, wherein the receiving comprises:

receiving, at the receiver, more recent backfill data is received more frequently, when compared to older backfill data.

21. An apparatus comprising:

at least one processor; and

at least one memory including computer program code which when executed causes operations comprising;

receiving, at the apparatus, backfill data representative of sensor data stored, at continuous blood glucose sensor and transmitter assembly, due to a loss of a wireless link between the apparatus and the continuous blood glucose sensor and transmitter assembly;

generating, at the apparatus, at least one of a notification or a graphically distinct indicator for presentation at a display of the apparatus, the at least one of the notification or the graphically distinct indicator enabling the backfill data to be graphically distinguished, when presented at the display, from non-backfill data; and

generating, at the apparatus, a view including the backfill data, the non-backfill data, and the generated at least one of the notification or the graphically distinct indicator.

22. The apparatus of claim 21, wherein the graphically distinct indicator comprises a color that is different from another color used to present the non-backfill data.

23. The apparatus of claim 21, wherein the graphically distinct indicator comprises a symbol that is different from another symbol used to present the non-backfill data.

24. The apparatus of claim 21, wherein the symbol comprises at least one of a dashed line, a solid line, a solid polygon, or a hollow polygon.

25. The apparatus of claim 21, wherein the graphically distinct indicator comprises an overlay on the backfill data.

26. The apparatus of claim 21, wherein the notification comprises an indication that the non-backfill data is being presented at the display.

27. The apparatus of claim 21, wherein the notification indicates at least one alert occurring during a time associated with the backfill data.

28. The apparatus of claim 21, wherein the notification indicates a request to display the backfill data associated with a missed alert.

29. The apparatus of claim 21, wherein the notification indicates a request to consent to the display of the backfill data.

30. A non-transitory computer-readable storage medium including program code which when executed by at least one processor causes operations comprising:

receiving, at the apparatus, backfill data representative of sensor data stored, at continuous blood glucose sensor and transmitter assembly, due to a loss of a wireless link between the apparatus and the continuous blood glucose sensor and transmitter assembly;

generating, at the apparatus, at least one of a notification or a graphically distinct indicator for presentation at a display of the apparatus, the at least one of the notification or the graphically distinct indicator enabling the backfill data to be graphically distinguished, when presented at the display, from non-backfill data; and

generating, at the apparatus, a view including the backfill data, the non-backfill data, and the generated at least one of the notification or the graphically distinct indicator.
