Intelligent control close-loop artificial pancreas system

Abstract

The invention discloses an intelligent control close-loop artificial pancreas system, comprising a continuous glucose monitoring device, an intelligent controller, and an insulin infusion device. The continuous glucose monitoring device is used to continuously monitor blood sugar concentration of a human body according to set interval. The intelligent controller is used to receive human body blood sugar monitoring data of the continuous glucose monitoring device in real time, and according to the real-time human body blood sugar monitoring data, by using a built-in fuzzy self-adaption proportion calculus control algorithm, calculates real-time insulin infusion device dosage. The insulin infusion device is used to receive the real-time insulin infusion device dosage of the intelligent controller, and perform real-time insulin on human bodies according to the real-time insulin infusion device dosage. The system can greatly reduce fluctuation range of human body blood sugar, and control blood glucose level in a set target interval, and improves accuracy and effectiveness of an insulin injection therapy, and makes blood glucose level of diabetics close to or reach standard of normal people, thereby greatly reducing various complications and improving living quality of the patients.

Description

technical field [0001] The invention relates to an artificial pancreas system, in particular to an intelligently controlled closed-loop artificial pancreas system, which belongs to the field of diabetes treatment equipment. Background technique [0002] Closed-loop artificial pancreas (AP) generally includes three parts: continuous glucose monitoring system (Continuous Glucose Monitoring System, CGMS), control algorithm (Control Algorithm, CA) and insulin pump (Insulin Pump) for precise insulin infusion. , IP). [0003] Over the past 40 years, experts from various countries have made a lot of important progress in the three aspects of artificial pancreas (CGMS, IP and CA), and currently there are more mature CGMS and IP products on the market. The control algorithm is the brain of the artificial pancreas. Since the 21st century, some researches on AP control algorithms abroad have entered the stage of clinical trials. Among these algorithms, there are three types that have...

Problems solved by technology

Although the patent includes an automatic glucose sensing system, a blood sugar control system for analyzing blood sugar concentration and calculating the optimal dosage of medication, and an automatic insulin injection system, it does not clarify whether the system is closed-loop control or real-time control, and its It is not clear what technology the core blood sugar control system uses for control, so it does not reflect the latest development trend of artificial pancreas technology
