Abstract

Methods and apparatus for providing data processing and control for use in a medical communication system are provided.

Core Innovation

A medical telemetry or monitoring system receives sensor data corresponding to a monitored glucose level from a glucose sensor with a portion positioned in contact with a fluid under a skin layer. The system monitors for one or more adverse data condition occurrences associated with the glucose sensor based on the sensor data, including identifying a first data quality flag from a plurality of data quality fields included in the sensor data.

When the particular adverse data condition occurrence exceeds a predetermined threshold during a time period, the system generates a notification configured to be provided to a user and displays the notification on a display of a receiving device. The document also describes data quality verification using error flags and buffering of prior samples, and uses uncertainty or variance thresholds to determine whether to disable or withhold glucose trend and rate-of-change outputs when data are unreliable.

The system additionally supports sensor calibration and sensitivity characterization, including composite sensitivity determination, outlier verification, and sensitivity stability verification. It also includes sensor insertion/removal detection with a state machine and user prompts, and incorporates ambient temperature compensation and filtering of sensor signals, with digital anti-aliasing.

Claims Coverage

The independent claims are clm-00001 (method) and clm-00015 (system). Both claims share a common inventive structure: receiving monitored glucose sensor data, detecting adverse data condition occurrences via data quality flags, generating a notification when a condition exceeds a threshold during a time period, and displaying the notification on a receiving device. The inventive features below reflect the key functional and structural elements emphasized in the independent claims.

Monitoring adverse data condition using data quality flags

Monitoring for one or more adverse data condition occurrences associated with the glucose sensor based on the sensor data, wherein monitoring comprises identifying a first data quality flag from a plurality of data quality fields included in the sensor data, wherein the first data quality flag indicates a particular adverse data condition occurrence.

Threshold-based user notification on display

Generating a notification configured to be provided to a user when the particular adverse data condition occurrence exceeds a predetermined threshold during a time period; and displaying the notification on a display of a receiving device.

Glucose sensor under a skin layer in contact with a fluid

Receiving sensor data corresponding to a monitored glucose level from a glucose sensor, at least a portion of the glucose sensor being positioned in contact with a fluid under a skin layer.

Receiving device that displays the notification

A receiving device, comprising a display, one or more processors, and at least one memory storing instructions which, when executed by the one or more processors, cause the receiving device to receive sensor data, monitor for adverse data condition occurrences using the first data quality flag, generate the notification when the adverse condition exceeds the threshold during the time period, and display the notification on the display.

Across clm-00001 and clm-00015, the claim coverage centers on using data quality flags within sensor data to identify adverse data condition occurrences, triggering a user notification only when a flagged condition exceeds a threshold during a time period, and displaying that notification on a receiving device. The glucose sensor is positioned in contact with a fluid under a skin layer, and the receiving device executes the flag-based monitoring and display of the generated notification.
