Abstract

A physiological characteristic monitoring system includes a physiological characteristic sensor that observes a physiological characteristic and generates sensor signals based on the observation. The physiological characteristic sensor includes a sensor connector. The physiological characteristic monitoring system includes a wearable device to be worn by a user in a first configuration and having a connector to couple to the sensor connector in a second configuration. The wearable device includes a controller that receives the sensor signals from the physiological characteristic sensor in the second configuration and determines a current value of the physiological characteristic based on the sensor signals.

First claim

What is claimed is:

1. A physiological characteristic monitoring system, comprising:
a glucose sensing device comprising a glucose sensor, a sensor base having a first connector, and an adhesive patch coupled to the sensor base, the adhesive patch configured to adhere to skin of a user and to secure the glucose sensor to an anatomy of the user to sense glucose levels;
a wearable band configured to be worn by the user, the wearable band being separate from the glucose sensing device and comprising a second connector; and
a display device comprising a controller, a display, a third connector, and a fourth connector, wherein the third connector is complementary to the first connector and is configured to couple to and uncouple from the first connector such that the display device can attach to and detach from the glucose sensing device, and wherein the fourth connector is complementary to the second connector and is configured to couple to and uncouple from the second connector such that the display device can attach to and detach from the wearable band,
wherein when the display device is attached to the glucose sensing device and is not attached to the wearable band, the controller is configured to cause the display to present at least a first user interface based on the glucose levels sensed by the glucose sensor, and
wherein when the display device is attached to the wearable band and is not attached to the glucose sensing device, the controller is configured to cause the display to present at least a second user interface, the second user interface being different from the first user interface.

2. The physiological characteristic monitoring system of claim 1 , further comprising an electronic device, wherein the electronic device is in communication with the display device.

3. The physiological characteristic monitoring system of claim 2 , wherein the controller of the display device is configured to store the glucose levels in a physiological datastore and, based on a data request from the electronic device, the controller of the display device is configured to output stored glucose levels as user data for the electronic device.

4. The physiological characteristic monitoring system of claim 3 , wherein based on the user data, the electronic device is configured to output an alert to a medical provider.

5. The physiological characteristic monitoring system of claim 1 , wherein the display device further comprises at least one activity sensor configured to observe an activity level of the user and to generate sensor signals based on the observation, wherein the controller is configured to cause the display to present the second user interface based on the activity level of the user.

6. The physiological characteristic monitoring system of claim 1 , wherein the first user interface includes an indication of a current glucose value sensed by the glucose sensor.

7. The physiological characteristic monitoring system of claim 6 , wherein the controller of the display device is configured to determine whether the current glucose value exceeds a threshold, and to cause the display to present a prompt for the user to take medicine based on determining that the current glucose value exceeds the threshold.

8. The physiological characteristic monitoring system of claim 1 , wherein the glucose sensing device is a continuous blood glucose monitor.

9. The physiological characteristic monitoring system of claim 8 ,
wherein the glucose sensor is positioned within a subcutaneous tissue of the user.

10. The physiological characteristic monitoring system of claim 5 , wherein the at least one activity sensor includes at least one of: an accelerometer or a heart rate sensor,
wherein when the display device is attached to the wearable band and is not attached to the glucose sensing device, the controller is configured to cause the display to present the second user interface based on at least one of: an output of the accelerometer or an output of the heart rate sensor.
