Handset CSII version: The handset is a portable touch-screen device, which communicates directly with the insulin pump. Its primary function in PEPPER is to allow the user to precisely manage insulin therapy by accepting or rejecting bolus insulin dose recommendations, calculated by the CBR based decision support algorithm, via a graphical interface. In addition, it measures and automatically records glucose levels (via a built-in Blood Glucose (BG) strip reader) and allows logging of food intake and other parameters.
