Ultrasonic-based subcutaneous fat thickness measuring instrument

Abstract

Provided is an ultrasonic-based subcutaneous fat thickness measuring instrument, belonging to the field of fat thickness measuring instruments. A single-chip microcomputer serves as a main control module to send out a pulse string and input a high-voltage excitation circuit, when the output of the high-voltage excitation circuit is larger than or equal to 30 V, the transmitting end of an ultrasonic probe is driven to send out ultrasonic waves, meanwhile, the single-chip microcomputer timer starts timing; the ultrasonic waves penetrate through the skin and subcutaneous fat tissues, and a reflection echo is generated at the junction of a subcutaneous fat layer and a muscle layer and is received by the receiving end of the ultrasonic probe, the reflection echo is amplified by an amplifying circuit and then input to the main control module, the single-chip microcomputer is triggerred to generate interruption and timing; according to the time interval of transmitting the ultrasonic waves and the ultrasonic echoes and the propagation speed of the ultrasonic waves in the adipose tissues, or according to the fitting equation between the time interval and the subcutaneous fat thickness, thesubcutaneous fat thickness is calculated; the thickness of the subcutaneous fat can be directly displayed on the display module, namely the display instrument, and can also be uploaded to the mobilephone through a bluetooth module. The subcutaneous fat thickness of any part of the body can be measured conveniently, rapidly and noninvasively.

Description

technical field [0001] The invention relates to an instrument for measuring the thickness of subcutaneous fat of a human body by using ultrasonic waves, and belongs to the field of measuring instruments for fat thickness. Background technique [0002] With the progress of society and the improvement of people's living standards, obesity and the diseases it causes have attracted more and more attention. Obesity is often accompanied by diabetes, fatty liver, blood lipid disorder, hypertension, coronary heart disease and other chronic diseases. It is one of the diseases that seriously affect people's health and quality of life, and has become a serious public health problem faced by countries all over the world. In China, the traditional diet structure has changed, the proportion of obese or overweight people is increasing, and the problem of population obesity is becoming more and more serious. [0003] Subcutaneous fat accounts for 40–60% of the total body fat, so detecting ...
