题目:An Integrative Model for Close Loop Control of Exogenous Insulin Injection for Type 1 Diabetes

 

报告人: Prof. Jiaxu Li (University of Louisville ,USA)

Abstract: Approximately 11% people in both US and China are diabetics. Among them, 15.3 million Chinese people and 3.6 million Americans suffer type 1 diabetes mellitus (T1DM). T1DM is resulted from the total loss or almost total loss of insulin producing pancreatic beta-cells. Exogenous insulin must be therefore administered daily to correct the hyperglycemia and prevent complications, ideally using an insulin pump. Currently all the clinical insulin administrations are in the open loop fashion, that is, insulin is injected according to proposed glucose level instead of truly measured plasma glucose concentration. To close the loop, it has been an endeavor of researchers and engineers to formulate effective, efficient and reliable models and develop control algorithms accordingly. In this talk, we showcase an integrated system consisting of body, glucose monitoring system (GMS), control model, and insulin injection by a pump. Our preliminary numerical simulations with actual clinical data from Carelink demonstrate that our model is more effective for the case of overnight control. This modular system could be enhanced to a true artificial pancreas system.
