Abstract

System and method for communicating glucose concentration information between devices of a continuous glucose monitoring system is provided. The continuous glucose monitoring system can include a sensor module generates a glucose concentration measurement data and transmits the data to one or more further devices of the continuous glucose monitoring system. The further devices can include a receiver unit and one or more secondary display devices. The receiver unit can be configured to be a stand-alone device of or physically connect to a secondary display device. A user interface can also be provided that provides enhanced functionality for using the continuous glucose monitoring system.

Claims

1. A method for configuring alert settings of a glucose monitoring system, comprising:

providing a receiver module having a set of configurable alert settings, wherein each of the set of configurable alert settings is initially set to a first, default setting configuration;

coupling the receiver module to a secondary display device having a user interface capable of receiving user input;

receiving user input from the secondary display device indicative of one or more alert setting modifications;

modifying one or more of the set of alert settings in accordance with the user input into a second configuration that is different than the first, default setting configuration and

automatically resetting the set of configurable alert settings to the first, default setting configuration upon a detection of a predetermined event, wherein the predetermined event comprises a data corruption error or a device hacking indication.

2. The method of claim 1, wherein the set of configurable alert settings comprises one or more settings selected from a group consisting of:

a hypoglycemic setting, a hyperglycemic setting, a rate-of-change setting and a calibration setting.

3. The method of claim 1, wherein the first, default setting configuration comprises a setting indicative of a hypoglycemic event threshold and a setting indicative of a hyperglycemic event threshold, the method further comprising activating an alarm of the receiving module if one of the event thresholds is exceeded.

4. A continuous glucose monitoring system for monitoring a glucose concentration of a host, the system comprising:

a continuous glucose sensor;

a sensor electronics unit electrically coupled to the continuous glucose sensor, the sensor electronics unit configured to generate sensor data indicative of a glucose concentration of a host using the continuous glucose sensor and configured to intermittently wirelessly transmit the sensor data; and

a mobile digital device having a glucose monitoring application stored in non-transitory memory therein, the glucose monitoring application comprising instructions that, when executed by a processor of the mobile digital device, causes the mobile digital device to

receive and process the sensor data transmitted from the sensor electronics unit,

display a user-selectable icon associated with the glucose monitoring application on a user interface of the mobile digital device, wherein the icon includes a displayed glucose value generated from the processed sensor data and

launch the glucose monitoring application in response to detection of a user selection of the user-selectable icon,

wherein the instructions of the glucose monitoring application, when executed by the processor, causes the mobile digital device to update the displayed glucose concentration on the user-selectable icon based on the received and processed sensor data including a new glucose concentration of the host detected by the continuous glucose sensor.

5. The system of claim 4, wherein the mobile digital device is a smart phone.

6. The system of claim 4, wherein the mobile digital device is configured to run the continuous glucose monitoring application in a background mode and a foreground mode, wherein the launch of the glucose monitoring application causes the mobile digital device to run the continuous glucose monitoring application in the foreground mode.

7. The system of claim 6, wherein the mobile digital device performs the displaying of the user-selectable icon in the background mode.

8. The system of claim 7, wherein the glucose monitoring application comprises one or more user-modifiable alert settings that cause the mobile digital device to trigger an alarm if the received sensor data satisfy the one or more alert settings.

9. The system of claim 8, wherein the mobile digital device is configured to trigger the alarm while in the background mode.

10. The system of claim 6, wherein the mobile digital device displays a retrospective view of the received sensor data while the glucose monitoring application is in the foreground mode.

11. The system of claim 4, wherein the continuous glucose monitoring application was downloaded on the mobile digital device from a remote server.
