Model-Based Analysis and Synthesis of Insulin Infusion Pump Usage Strategies
Sriram Sankaranarayanan ( U Colorado )
Insulin infusion pumps are commonly used by diabetic patients to control their
blood glucose levels. The everyday use of these pumps can be challenging, requiring
accurate meal planning and appropriate timing of insulin bolus infusions. Combinations of
mechanical faults, software errors and user mistakes can lead to dangerous
conditions such as hypoglycemia and hyperglycemia.
In this talk, we explore the use of mathematical models of the insulin-glucose
regulatory system in conjunction with models of the pump and the usage strategies
to analyze the impact of various common faults that occur during insulin infusion. We use
a promising heuristic approach to state-space exploration for non-linear systems called
robustness-guided model checking to analyze the resulting model and infer root causes for
common risks such as hypoglycemia and hyperglycemia. Finally, we present some ideas on how
model-based analysis techniques can be transformed into software tools that can help diabetic
patients better control their blood glucose levels, and some progress in this direction.
