Abstract

The present embodiments harness a wide variety of capabilities of modern smartphones, and combine these capabilities with information from a continuous glucose monitor to provide diabetics and related people with more information than the continuous glucose monitor can provide by itself. The increased information provides the diabetic with an increased likelihood of good diabetes management for better health.

Claims

1. A machine-executed method of continuous analyte monitoring for a host to facilitate management of the host'"'"'s blood glucose level, the method comprising:

receiving a first input from a continuous analyte monitor (CAM) device including analyte concentration data of the host;

receiving or determining an expected maximum value and an expected minimum reference value;

receiving a first reference value from a reference analyte monitor;

processing the first reference value by comparing it to the expected maximum value and the expected minimum value; and

producing an output of an alert to obtain a second reference value if the first reference value does not meet the range defined by the expected maximum value and the expected minimum value.

2. The method of claim 1, wherein the method of claim 1 is performed by a hand-held computing device in wireless communication with the CAM, and wherein the CAM comprises a continuous analyte sensor coupled to CAM electronics, the CAM electronics configured to calibrate the continuous analyte sensor output.

3. The method of claim 2, wherein the CAM electronics determines the expected maximum reference value and the expected minimum reference value and transmits each of the expected maximum reference value, the expected minimum reference value and the calibrated continuous analyte sensor output to the hand-held computing device.

4. The method of claim 3, further comprising periodically and regularly establishing a wireless communication channel between the CAM electronics and the hand-held computing device, and wherein the transmitting occurs within an established communication channel.

5. The method of claim 3, wherein the CAM electronics periodically generates a calibrated continuous sensor data value.

6. The method of claim 5, wherein both the period for establishing the communication channel and the period for generating the calibrated continuous sensor data value are substantially the same.

7. The method of claim 6, wherein both of the establishing period and the generating period are 1, 5 or 10 minutes.

8. The method of claim 2, wherein the reference analyte monitor is a single-point blood glucose monitor, and wherein the receiving the first reference analyte value comprises receiving a user input on a user interface of the hand-held computing device.

9. The method of claim 2, further comprising displaying the first reference analyte value on the display of the hand-held computing device if the first reference analyte value meets the range defined by the expected maximum value and the expected minimum value, wherein the first reference value is displayed on the hand-held computing device until a calibrated continuous analyte sensor value based on the first reference value is received from the CAM and displayed on the hand-held computing device display.

10. The method of claim 9, wherein the first reference value is displayed differently than the calibrated continuous analyte sensor value by displaying the first reference value is a different color and/or font size than the calibrated CGM value.

11. A system for continuous analyte monitoring for a host to facilitate management of the host'"'"'s blood glucose level, the method comprising:

a hand-held computing device configured to receive a first input from a continuous analyte monitor (CAM) device including analyte concentration data of the host;

receive or determine an expected maximum value and an expected minimum reference value;

receive a first reference value from a reference analyte monitor;

process the first reference value by comparing it to the expected maximum value and the expected minimum value; and

produce an output of an alert to obtain a second reference value if the first reference value does not meet the range defined by the expected maximum value and the expected minimum value.

12. The system of claim 11, wherein the CAM comprises a continuous analyte sensor coupled to CAM electronics, the CAM electronics configured to calibrate the continuous analyte sensor output.

13. The system of claim 12, wherein the CAM electronics are configured to determine the expected maximum reference value and the expected minimum reference value and transmits each of the expected maximum reference value, the expected minimum reference value and the calibrated continuous analyte sensor output to the hand-held computing device.

14. The system of claim 13, wherein the hand-held computing device is configured to regularly establish a wireless communication channel with the CAM electronics, and wherein the CAM electronics transmits each of the expected maximum reference value, the expected minimum reference value and the calibrated continuous analyte sensor output to the hand-held computing device within the established communication channel.

15. The system of claim 13, wherein the CAM electronics are configured to periodically generate a calibrated continuous sensor data value.

16. The system of claim 15, wherein both the period for establishing the communication channel and the period for generating the calibrated continuous sensor data value are substantially the same.

17. The system of claim 16, wherein both of the establishing period and the generating period are 1, 5 or 10 minutes.

18. The system of claim 12, wherein the reference analyte monitor is a single-point blood glucose monitor, and wherein the receiving the first reference analyte value comprises receiving a user input on a user interface of the hand-held computing device.

19. The system of claim 12, wherein the hand-held computing device is further configured to display the first reference analyte value on the display of the hand-held computing device if the first reference analyte value meets the range defined by the expected maximum value and the expected minimum value, and wherein the hand-held computing device is configured to display the first reference value until a calibrated continuous analyte sensor value based on the first reference value is received from the CAM.

20. The system of claim 19, wherein the first reference value is displayed differently than the calibrated continuous analyte sensor value by displaying the first reference value is a different color and/or font size than the calibrated CGM value.
