Abstract

Claims (39)

1. A continuous glucose monitoring system, comprising:

a glucose sensor having a first portion configured to be positioned through a user's skin and in contact with an interstitial fluid of the user for in vivo detection of glucose and a second portion configured to remain above the user's skin;

a non-transitory memory; and

at least one processor communicatively coupled to the non-transitory memory and the glucose sensor and configured to:

receive a current blood glucose measurement of the user determined based on a finger prick test using a lancing device in conjunction with a blood glucose meter;

provide a prompt to accept or decline execution of a calibration routine using the current blood glucose measurement;

upon receiving an acceptance to the prompt to accept or decline execution of a calibration routine using the current blood glucose measurement, confirm:

(1) that the current blood glucose measurement is within a glucose-value range, and

(2) that a rate of change of a glucose level detected by the glucose sensor is within a rate-of-change range;

upon confirming (1) and (2) initiate the calibration routine and calibrate the glucose sensor using the current blood glucose measurement;

wherein if a declination to the prompt to accept or decline execution of a calibration routine using the current blood glucose measurement is received, the at least one processor is further configured to store the current blood glucose measurement.

2. The system of claim 1 , wherein the glucose-value range is between 40 mg/dL and 400 mg/dL.

3. The system of claim 1 , wherein upon receiving the acceptance to the prompt to accept or decline execution of the calibration routine using the current blood glucose measurement, the processor is further configured to confirm a number of analyte sensor data points to initiate the calibration routine is above a threshold.

4. The system of claim 1 , wherein upon receiving the acceptance to the prompt to accept or decline execution of the calibration routine using the current blood glucose measurement, the processor is further configured to confirm that a temperature associated with the glucose monitoring system is within a temperature range.

5. The system of claim 1 , wherein the calibration routine comprises storing the current blood glucose measurement.

6. The system of claim 1 , wherein the processor is further configured to determine if the calibration routine failed.

7. The system of claim 6 , wherein the processor is further configured to provide a notification if the calibration routine failed.

8. The system of claim 1 , wherein the processor is further configured to store a calibration schedule in the non-transitory memory, wherein the calibration schedule comprises a plurality of scheduled calibration events for receiving scheduled blood glucose measurements to calibrate the glucose sensor.

9. The system of claim 8 , wherein the processor is further configured to determine if the current blood glucose measurement is within a predetermined time period from an upcoming scheduled calibration event.

10. The system of claim 9 , wherein the processor is further configured to update the calibration schedule to replace the upcoming scheduled calibration event with the calibration routine.

11. The system of claim 9 , wherein the predetermined time period is 90 minutes.

12. A method comprising:

receiving, by at least one processor, a current blood glucose measurement of the user determined based on a finger prick test using a lancing device in conjunction with a blood glucose meter;

providing, by the at least one processor, a prompt to accept or decline execution of a calibration routine using the current blood glucose measurement;

upon receiving an acceptance to the prompt to accept or decline execution of a calibration routine using the current blood glucose measurement, confirming, by the at least one processor:

(1) that the current blood glucose measurement is within a glucose-value range, and

(2) that a rate of change of a glucose level detected by a glucose sensor is within a rate-of-change range;

upon confirming (1) and (2), initiating, by the at least one processor the calibration routine and calibrate the glucose sensor using the current blood glucose measurement;

wherein if a declination to the prompt to accept or decline execution of a calibration routine using the current blood glucose measurement is received, storing, by the at least one processor, the current blood glucose measurement.

13. The method of claim 12 , wherein the glucose-value range is between 40 mg/dL and 400 mg/dL.

14. The method of claim 12 , wherein upon receiving the acceptance to the prompt to accept or decline execution of the calibration routine using the current blood glucose measurement, the method further comprises confirming, by the at least one processor, a number of analyte sensor data points to initiate the calibration routine is above a threshold.

15. The method of claim 12 , wherein upon receiving the acceptance to the prompt to accept or decline execution of the calibration routine using the current blood glucose measurement, the method further comprises confirming, by the at least one processor, that a temperature associated with the glucose monitoring system is within a temperature range.

16. The method of claim 12 , wherein the calibration routine comprises storing the current blood glucose measurement.

17. The method of claim 12 , wherein the method further comprises determining, by the at least one processor, if the calibration routine failed.

18. The method of claim 17 , wherein the method further comprises providing, by the at least one processor, a notification if the calibration routine failed.

19. The method of claim 12 , wherein the method further comprises storing, by the at least one processor, a calibration schedule in the non-transitory memory, wherein the calibration schedule comprises a plurality of scheduled calibration events for receiving scheduled blood glucose measurements to calibrate the glucose sensor.

20. The method of claim 19 , wherein the method further comprises determining, by the at least one processor, if the current blood glucose measurement is within a predetermined time period from an upcoming scheduled calibration event.

21. The method of claim 20 , wherein the method further comprises updating, by the at least one processor, the calibration schedule to replace the upcoming scheduled calibration event with the calibration routine.

22. The method of claim 20 , wherein the predetermined time period is 90 minutes.
