The invention provides an intelligent
insulin closed-loop infusion
system for type 1
diabetes mellitus, and relates to the technical field of
diabetes mellitus treatment equipment. The
system comprises a
blood glucose monitoring module, a control module, an
insulin infusion module, a user interaction module, a
wireless communication module and a
power module, and closed-loop precise infusion of
insulin is achieved through cooperation of the multiple modules. Wherein a closed-loop
algorithm based on a dynamic basic rate formula is arranged in the control module, and the
insulin infusion amount can be dynamically adjusted in combination with an LSTM blood glucose prediction model and a metabolic parameter least square method updating unit; the
insulin infusion module adopts a micro
peristaltic pump controlled by PWM (
Pulse Width Modulation) and a current monitoring type blockage detection unit, so that the infusion precision and safety are guaranteed. According to the
system, the blood glucose standard reaching time proportion can be increased to 78%, the
hypoglycemia occurrence frequency is reduced to 0.8 times per week, the system is remarkably superior to a traditional
insulin pump and a simple closed-loop system, meanwhile, the system has the advantages of being long in sensor service life and low in
power consumption, and the treatment convenience and safety of type 1 diabetes patients are improved.
