Abstract

Embodiments described herein relate to an analyte monitoring device having a user interface with a display and a plurality of actuators. The display is configured to render a plurality of display screens, including a home screen and an alert screen. The home screen is divided into a plurality of simultaneously displayed panels, with a first panel displays a rate of change of continuously monitored analyte levels in interstitial fluid, a second panel simultaneously displays a current analyte level and an analyte trend indicator, and a third panel displays status information of a plurality of components of the device. When an alarm condition is detected, the display renders the alert screen in place of the home screen, the alert screen displaying information corresponding to the detected alarm condition. Furthermore, the actuators are configured to affect further output of the analyte monitoring device corresponding to the detected condition.

Core Innovation

The invention concerns a glucose monitoring device and system that receive processed glucose data indicative of monitored glucose levels from a transcutaneous glucose sensor positioned at least in part in contact with interstitial fluid in a body of a user. The processing circuitry detects a high glucose condition associated with the glucose data and defines an alarm-decision process in relation to the persistence of the detected high glucose condition over time.

After detecting the high glucose condition, the processing circuitry suppresses output of an alarm through a user interface for a predetermined wait period that is user-selectable. After expiry of the predetermined wait period, the processing circuitry detects whether the high glucose condition still exists, and the user interface outputs the alarm only when the high glucose condition still exists after the expiry of the predetermined wait period.

In certain refinements, the high glucose condition is detected when received glucose data is above a predetermined threshold level associated with the high glucose condition, including when a first occurrence of received glucose data exceeds the predetermined threshold level. The predetermined threshold level may be user-selectable within a predetermined range, and the persistence determination is performed by detecting that the received glucose data remains above the predetermined threshold after the predetermined wait period has expired.

Claims Coverage

The independent claims center on suppressing alarm output for a user-selectable predetermined wait period and outputting the alarm only if the high glucose condition still exists after the wait period expires. Dependent claims add threshold-based and first-occurrence detection refinements, persistence determination relative to the threshold, user-selectable threshold range limitations, and user interface refinements including a touch-sensitive display, an illuminated test strip port, and a movable color-coded rate-of-change display concept.

The claims collectively cover glucose-monitoring alarm logic that suppresses alarm output for a user-selectable predetermined wait period and then outputs the alarm only when the high glucose condition is determined to still exist after that wait period. Dependent claims further specify how the high glucose condition is detected, how persistence is determined after the wait period, and that the threshold may be user-selectable within a predetermined range, with additional receiver and user-interface refinements.
