INFUSION DEVICES AND RELATED PATIENT RATIO ADJUSTMENT METHODS

摘要

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method of operating an infusion device to deliver a bolus amount of fluid influencing a physiological condition in a body of a user involves identifying, based on measurement values for the physiological condition, a residual value for the physiological condition resulting from the bolus amount of the fluid and determining an updated ratio for a subsequent bolus by adjusting an initial ratio influencing the bolus amount to compensate for the residual value. The updated ratio may be stored in a data storage element for use in determining a subsequent bolus amount in lieu of the initial ratio value.
