Virtual Environment Model of Glucose Homeostasis for Diabetes Patients

A medical device is designed to meet the patient specific requirements. The required biological behaviour of the medical device is driven by mostly the operating environment. Most of the time, a medical device fails due to lack of understanding of the system requirements, including the functional and non-functional requirements. For example, the U.S. Food and Drug Administration (FDA) has reported a large number of serious illnesses and deaths related to IIP. Our approach is to trigger hidden requirements at an early stage of the system development. In order to achieve our goal, this paper proposes an abstract development of virtual environment model of the glucose homeostasis for diabetes patients to analyze the patient specific medical devices, such as an Insulin Infusion Pump (IIP). The main objective of this environment model is to assist in the construction, clarification, and validation of the system requirements by developing and designing the closed-loop model of medical devices.
