Developrnent of an Educational Simulator and Graphical User Interface for Diabetic Patients

This paper presents an educational simulator and graphical user interface for type 1 diabetes patients. The educational simulator is conformed by three mathematical models which describe the glucose-insulin dynamics using a compartmental model, with additional equations to reproduce aerobic exercise, gastric glucose absorption by the gut, and subcutaneous insulin absorption. Moreover, multiple daily doses and continuous insulin infusions can be simulated in order to implement an intensive insulin therapy. The mathematical models, integration methods and insulin dosing strategies were implemented in Java programming language. As a result, the Java Educational Diabetes Management Advisor (JEDMA) shows the influence of exercise periods, food intakes, and intensive insulin therapies on the glucose concentrations.
