Abstract

Described herein are analyte monitoring systems including a receiver or data processing component that is configured to automatically issue a first alert notification when a first predetermined number of consecutive data packets are not received from the sensor/sensor electronics, and automatically issue a second alert notification when a second predetermined number of consecutive data packets are not received by the sensor/sensor electronics. The receiver may also be configured to enable a user to disenable alert or alarm notifications that are triggered based on detected events.

Claims

1. An analyte monitoring system, comprising:

sensor electronics operatively coupled to an analyte sensor in fluid contact with interstitial fluid and configured to generate a data packet including a current analyte value and a plurality of prior analyte values; and

a data receiver in signal communication with the sensor electronics and configured to receive the data packet from the sensor electronics, the data receiver further configured to automatically output a first alert notification when a first predetermined number of data packets is not received by the data receiver, and automatically output a second alert notification when a second predetermined number of data packets is not received by the data receiver.

2. The analyte monitoring system of claim 1, wherein the second alert notification is different than the first alert notification.

3. The analyte monitoring system of claim 1, wherein each of the first alert notification and the second alert notification is one of an auditory notification, a tactile notification or a visual notification.

4. The analyte monitoring system of claim 1, wherein the data receiver is configured to automatically output the first alert notification when a first predetermined number of consecutive data packets is not received by the data receiver, and automatically output the second alert notification when a second predetermined number of consecutive data packets is not received by the data receiver.

5. A method, comprising:

outputting a first alert notification type when a first predetermined number of data packets is not received; and

outputting a second alert notification type when a second predetermined number of data packets is not received, wherein the first alert notification type is output at a first predetermined output level and wherein the second alert notification type is output at a second predetermined output level.

6. The method of claim 5, further comprising anticipating receipt of a subsequent data packet at a first predetermined period of time when the first predetermined number of data packets is not received.

7. The method of claim 6, wherein the first predetermined period of time is based, at least in part, on the first predetermined number of data packets that is not received.

8. The method of claim 5, further comprising anticipating receipt of a subsequent data packet at a second predetermined period of time when the second predetermined number of data packets is not received.

9. The method of claim 8, wherein the second predetermined period of time is based, at least in part, on the second predetermined number of data packets that is not received.

10. The method of claim 5, wherein the first alert notification type is disabled when a subsequent data packet is received.

11. The method of claim 5, wherein the first alert notification type is disabled when a predetermined number of subsequent data packets is received.

12. The method of claim 5, wherein the second alert notification type is disabled when a subsequent data packet is received.

13. The method of claim 5, wherein the second alert notification type is disabled when a predetermined number of subsequent data packets is received.

14. The method of claim 5, further comprising selectively disabling at least one of the first alert notification type or the second alert notification type.

15. The method of claim 5, wherein the first alert notification type is output when a first predetermined number of consecutive data packets is not received, and further, wherein the second alert notification type is output when a second predetermined number of consecutive data packets is not received.

16. A method, comprising:

detecting an occurrence of a predetermined routine;

outputting a first notification of an alarm condition at a first output level when a first number of data packets is not received; and

outputting a second notification of the alarm condition at a second output level when termination of the predetermined routine is detected.

17. The method of claim 16, wherein the first notification of the alarm condition is output concurrently with the occurrence of the predetermined routine.

18. The method of claim 16, further comprising disabling at least one of the first notification and the second notification.

19. The method of claim 16, wherein the predetermined routine is one of a blood glucose test, a calibration routine, or a medication dosage adjustment.

20. The method of claim 16, wherein detecting the occurrence of the alarm condition includes detecting the alarm condition when a first predetermined number of consecutive data packets is not received.
