INTEGRATED USER-DEFINED INPUT INTO A CLOSED-LOOP GLUCOSE CONTROL SYSTEM

摘要

A controller in a system for automatic control of blood glucose level of a subject is operative to generate an insulin dose control signal for controlling insulin delivery by a delivery device, based on time-varying glucose levels of the subject as represented by an actual glucose level signal over time. The controller operates at a regular frequency to generate the insulin dose control signal to regulate the glucose levels in the subject and employs a control algorithm that functions in conjunction with and accounting for user-determined doses, such as meal doses, whose values are entered into the controller and delivered on command of a user.
