Closed-loop artificial pancreas system based on wearable monitoring method

Abstract

The invention discloses a closed-loop artificial pancreas system based on a wearable monitoring method. The system comprises a wearable blood glucose monitoring sub-module, a diet and exercise monitoring sub-module, a calculation control sub-module, an insulin infusion sub-module and an effect evaluation sub-module, wherein the wearable blood glucose monitoring sub-module is used for acquiring a blood glucose sensing signal in a noninvasive mode by virtue of wearable equipment; the diet and exercise monitoring sub-module is used for acquiring diet monitoring data and exercise monitoring data which can cause the change of blood glucose concentration of a to-be-tested person; the calculation control sub-module is used for acquiring insulin infusion related information by virtue of a traineddeep learning model in accordance with the blood glucose sensing signal, the diet monitoring data and the exercise monitoring data; the insulin infusion sub-module is used for automatically implementing insulin infusion; and the effect evaluation sub-module is used for evaluating an insulin infusion effect and for feeding an evaluation result back to the calculation control sub-module, so that thecalculation control sub-module can determine whether to update the insulin infusion related information or not. The closed-loop artificial pancreas system provided by the invention is convenient, comfortable, low in cost, high in applicability and high in reliability.

Description

technical field [0001] The invention relates to the field of medical and health technologies, and more specifically, to a closed-loop artificial pancreas system based on a wearable monitoring method. Background technique [0002] Diabetes mellitus is a metabolic disease characterized by hyperglycemia, which is caused by defective insulin secretion or impaired biological action, or both. At present, there is no feasible cure for diabetes. Diabetic patients, especially type I diabetic patients, need to adjust the dose of insulin in time by measuring blood sugar concentration, so as to control blood sugar level and prevent or reduce diabetic complications. [0003] Current methods for controlling blood sugar levels include: 1) Using a minimally invasive blood glucose meter to obtain the blood glucose concentration of the patient, and adjusting the dose of insulin according to the blood glucose concentration. Dangerous, and this method cannot achieve real-time insulin dose adju...

AI Technical Summary

Problems solved by technology

In the prior art, the defects of the artificial pancreas system are: the artificial pancreas system realizes the acquisition of blood glucose concentration data through the implanted CGM sensor, and the implanted CGM sensor will cause allergies and infections in the patient, and the sensor life is short , needs to be replaced regularly, and the cost of use is high; at present, the artificial pancreas system does not consider the influence of diet and exercise on blood sugar concentration changes, resulting in poor performance of the automatic insulin infusion function of the artificial pancreas system in the above cases
