Abstract

This disclosure provides systems, methods and apparatus for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor. The system may include a display device with at least one input device. In response to movement of or along the input device, the display device may change a glucose data output parameter and update an output of the display device using the changed output parameter.

Claims

1. A continuous analyte monitoring system configured to determine an end of life of a continuous analyte sensor, the system comprising sensor electronics configured to be operably connected to the continuous analyte sensor, the sensor electronics configured to:

evaluate one or more factors associated with remaining sensor life of a sensor;

determine a remaining sensor life of the sensor based on the evaluation of the factors; and

provide an output related to the remaining sensor life of the sensor,

wherein the one or more factors include at least one of;

accuracy of the glucose sensor data;

noise associated with the glucose sensor data; and

an algorithmic determination of sensor end-of-life based on sensor data.

2. The system of claim 1, wherein the output related to the remaining sensor life of the sensor comprises an indicator displayed on a user interface of the system.

3. The system of claim 2, wherein the indicator indicates to a user an estimated time period for which the current sensor is suitable for use.

4. The system of claim 2, wherein the estimated time period is represented by a graphical indicator of a portion of the sensor life that remains.

5. The system of claim 2, wherein the indicator is configured to be displayed only when sensor life is below a predetermined threshold.

6. The system of claim 1, wherein the output related to the remaining sensor life of the sensor comprises an indicator transmitted from the sensor electronics via a wireless data transmission.

7. A method for determining an end of life of a continuous analyte sensor used in a continuous analyte monitoring system, the system comprising sensor electronics configured to be operably connected to a continuous analyte sensor, the method comprising:

evaluating one or more factors associated with remaining sensor life of a sensor;

determining a remaining sensor life of the sensor based on the evaluation of the factors; and

providing an output related to the remaining sensor life of the sensor,

wherein the one or more factors include at least one of;

accuracy of the glucose sensor data;

noise associated with the glucose sensor data; and

an algorithmic determination of sensor end-of-life based on sensor data.

8. The method of claim 7, wherein the output related to the remaining sensor life of the sensor comprises an indicator displayed on a user interface.

9. The method of claim 8, wherein the indicator indicates to a user an estimated time period for which the current sensor is suitable for use.

10. The method of claim 8, wherein the estimated time period is represented by a graphical indicator of a portion of the sensor life that remains.

11. The method of claim 8, displaying the indicator only when sensor life is below a predetermined threshold.
