Abstract

Embodiments of the present disclosure include detecting a concurrent occurrence of a decrease in monitored analyte level and a corresponding decrease in monitored on-skin temperature, confirming a presence of an impending hypoglycemic condition, and asserting a notification corresponding to the confirmed impending hypoglycemic condition. Devices, methods, systems and kits incorporating the same are also provided.

First claim

What is claimed is:

1. A glucose monitoring device, comprising:
one or more processors; and
a memory storing instructions which, when executed by the one or more processors, cause the one or more processors to:
receive sensor data indicative of a glucose level from a glucose sensor when at least a portion of the glucose sensor is positioned in contact with a bodily fluid under a skin surface of a user;
determine a hypoglycemic condition of the user based on the glucose level;
apply, in response to determining the hypoglycemic condition, a hold condition to a notification for the hypoglycemic condition;
receive movement data collected by a second sensor, the movement data indicating movement of the user;
determine a change in the movement of the user based on the movement data;
confirm the determination of the hypoglycemic condition based on the change of the movement of the user;
remove, in response to confirming the hypoglycemic condition based on the change of the movement of the user, the hold condition associated with the notification for the hypoglycemic condition; and
output an indication of the confirmed hypoglycemic condition to a display, wherein the indication comprises the notification for the hypoglycemic condition.

2. The device of claim 1 , wherein the movement of the user comprises a tremor.

3. The device of claim 1 , wherein confirming the determination of the hypoglycemic condition further comprises adjusting the glucose level using the movement data.

4. The device of claim 1 , wherein the hypoglycemic condition is an impending hypoglycemic condition.

5. The device of claim 1 , wherein the indication of the confirmed hypoglycemic condition comprises an alarm based on the glucose level.

6. The device of claim 5 , wherein the alarm is related to the hypoglycemic condition.

7. The device of claim 5 , wherein the alarm or the alert is provided at least in part by removing the hold condition.

8. The device of claim 1 , wherein the device communicates with a receiver via a wired or wireless connection.

9. The device of claim 1 , wherein the device is connected to a data network for storing or retrieving the sensor data.

10. The device of claim 1 , wherein the device further comprises a touch-sensitive display configured to receive an input by the user.

11. The device of claim 1 , further comprises a data processing unit configured to receive and process the sensor data received from the glucose sensor.

12. The device of claim 1 comprising the memory storing instructions which, when executed by the one or more processors, cause the one or more processors to calibrate the sensor data received from the glucose sensor.

13. A glucose monitoring method, comprising:
receiving sensor data indicative of a glucose level from a glucose sensor when at least a portion of the glucose sensor is positioned in contact with a bodily fluid under a skin surface of a user;
determining a hypoglycemic condition of the user based on the glucose level;
applying, in response to determining the hypoglycemic condition, a hold condition to a notification for the hypoglycemic condition;
receiving movement data collected by a second sensor, the movement data indicating movement of the user;
determining a change in the movement of the user based on the movement data;
confirming the determination of the hypoglycemic condition based on the change of the movement of the user;
removing, in response to confirming the hypoglycemic condition based on the change of the movement of the user, the hold condition associated with the notification for the hypoglycemic condition; and
outputting an indication of the confirmed hypoglycemic condition to a display, wherein the indication comprises the notification for the hypoglycemic condition.

14. The method of claim 13 , wherein the movement of the user comprises a tremor.

15. The method of claim 13 , wherein confirming the determination of the hypoglycemic condition further comprises adjusting the glucose level using the movement data.

16. The method of claim 13 , wherein the hypoglycemic condition is an impending hypoglycemic condition.

17. The method of claim 13 , wherein the indication of the confirmed hypoglycemic condition comprises an alarm based on the glucose level.

18. The method of claim 17 , wherein the alarm is related to the hypoglycemic condition.

19. The method of claim 17 , wherein the alarm or the alert is provided at least in part by removing the hold condition.

20. The method of claim 13 , further comprising communicating the sensor data with a receiver via a wired or wireless connection.

21. The method of claim 13 , further comprising calibrating the sensor data received from the glucose sensor.
