Abstract

The invention relating to biomedicine detecting technique provides a non-invasive blood sugar fast detecting method and a device thereof. The method comprises steps of controlling a pulse laser to irradiate the skin tissue of a human body, using an ultrasonic transducer to detect the acoustic and light signals PA generated by the photoacoustic effect, using a photoelectric detector to detect scattered reflection photosignal A at the same time, and performing data analysis by using the acoustic and light signals PA and the reflection photosignal A to obtain a blood sugar concentration value to realize non-invasive blood sugar fast detecting. The device comprises a circuit part and an integrated probe, wherein, the circuit part comprises a central control processing unit and a photosignal collecting and amplifying circuit connected with the same, an acoustic and light signals collecting and amplifying circuit, a laser activation and modulation circuit, control function modules of displaying, storing, communicating, button-pressing and the like and an electric power. The integrated probe comprises a semiconductor pulsed laser, the ultrasonic transducer and the photoelectric detector.

Description

technical field [0001] The invention relates to the technical field of biomedical detection, and relates to a method and a device for non-invasive rapid detection of blood sugar. Background technique [0002] Diabetes mellitus is a common metabolic endocrine disease characterized by hyperglycemia, and is a worldwide epidemic. In recent years, with the development of my country's social economy, the improvement of residents' living standards, and the acceleration of population aging, the incidence of diabetes has been increasing year by year. At present, there are about 50 million diabetic patients in the country, and the annual growth rate is 0.1%. . Diabetes is harmful, mainly because of its serious complications, such as cardiovascular disease, kidney disease, eye disease, neuropathy and diabetic foot. There is currently no effective cure for diabetes, and blood sugar control is the only treatment. Timely blood glucose detection is of great significance for controlling d...
