Non-invasive blood-sugar detecting instrument based on conservation of energy

Abstract

The present invention discloses a noninvasive blood glucose detection instrument basing on the energy conservation principle, which includes a blood glucose detection sensor, a signal processing circuit, a simulation filter circuit, an amplifying circuit, an A/D converter, a communication circuit, a display, a single chip microcomputer, a personal computer and a blood oxygen detection module. The blood glucose detection sensor, the signal processing circuit, the simulation filter circuit, the amplifying circuit and the A/D converter are connected successively in series. The blood glucose detection instrument detects physiological quantity signals of a human body. The signals are pretreated by the signal processing circuit, the simulation filter circuit and the amplifying circuit and are converted into digital signals by the A/D converter to be transmitted to the single chip microcomputer. Then, the digital signals are transmitted to the personal computer through a communication circuit. The personal computer processes the detected data, finishes the calculation of the blood glucose concentration and displays the calculation results. Through the parameters of the detections of the convection, the radiation and the heat evaporation dissipating capacity of finger surfaces, the blood flow and the blood oxygen saturation of local tissues, etc., the present invention realizes the blood glucose fast detection, which has the advantages of painless performance, disinfection and simple and rapid performances.

Description

technical field [0001] The invention relates to a blood sugar detector for non-invasive detection of blood sugar concentration based on an energy conservation method. Background technique [0002] Diabetes mellitus is a chronic disease of carbohydrate, fat and protein metabolism disorder caused by relative or absolute deficiency of insulin in the body and decreased sensitivity of target cells to insulin, or structural defects in insulin itself. Its main feature is hyperglycemia , diabetes. It is clinically manifested as polydipsia, polyphagia, polyuria, and weight loss, which can cause morphological changes and dysfunction of some tissues or organs, accompanied by ketoacidosis, limb gangrene, polyneuritis, blindness, and renal failure, etc. . At present, the more effective means of controlling and treating diabetes is to strictly control the blood sugar concentration through frequent testing and insulin injection, so as to reduce or alleviate the long-term complications ca...
