Abstract

Method and system for providing basal profile modification in insulin therapy for use with infusion devices includes periodically monitoring the analyte levels of a patient for a predetermined period of time in order to determine, based on the monitored analyte levels, an appropriate modification factor to be incorporated into the underlying basal profile which was running at the time the periodic monitoring of the analyte levels were performed.

Core Innovation

A method for diabetes management receives glucose data corresponding to a glucose level of a user from a glucose monitor comprising a transcutaneous glucose sensor. One or more processors retrieve patient specific parameters comprising one or more of exercise, caloric intake or insulin sensitivity, and detect a pattern of glucose excursions in which the received glucose levels exceed a predetermined glucose level threshold.

The processors determine a glucose metric based on the received glucose levels and determine a modification to an insulin therapy profile when the pattern of glucose excursions is detected. The modification is determined based on a gain factor and a difference between the glucose metric and a target glucose metric, and the method outputs the modification to a medication delivery unit and implements the modification via the medication delivery unit.

The disclosed approach characterizes patterns of glucose excursions relative to predetermined glucose level thresholds and relates the resulting glucose metric to a target glucose metric through a gain factor. The modification to the insulin therapy profile is based on detected excursion patterns and a metric-to-target difference, rather than solely on a current glucose measurement.

Claims Coverage

The partial document includes two independent claims: a method for diabetes management and a corresponding system for diabetes management. Across both independent claims, there is one core inventive concept consisting of excursion-pattern detection from transcutaneous glucose sensor data and computing an insulin-therapy-profile modification using a gain factor applied to a glucose-metric versus target-glucose-metric difference.

The independent claims cover both performing the processing as a method and implementing the same processing logic in a system. The inventive scope is centered on detecting glucose excursion patterns from transcutaneous sensor data, computing a glucose metric, and determining an insulin-therapy-profile modification using a gain factor applied to a glucose-metric versus target-glucose-metric difference, followed by delivery and implementation through a medication delivery unit.
