Problems solved by technology

However, due to the complexity of the human body, it is impossible to accurately test the impedance of a certain part of the human body alone. Therefore, how to accurately obtain the impedance of the human abdomen is the key problem that needs to be solved first.

Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific examples.

[0044] The abdominal composition analyzer is designed to detect the impedance of the human abdomen, and obtain the composition of abdominal fat, overall fat, water, etc. Its principle is similar to measuring the resistivity of a conductor in electricity. Since each conductor has its specific resistivity, for a material with a known length, as long as its resistance is measured, the resistivity can be obtained through correlation calculations, and its constituent materials can be found. The volume of the conductor is regarded as the human body, the length of the conductor is replaced by the length of the measured human tissue, and the resistivity is the value of the resistance per unit volume of the human tissue. As long as the impedance value of the human body is measured...

Abstract

The invention discloses an abdominal component analyzer and an analysis method thereof; an abdominal component analysis model of a maximum posteriori estimation method is firstly used, then the model is trained by detecting sample human body abdominal bioelectrical impedance, and finally the human body abdominal bioelectrical impedance of a detected person is sent into the trained model so as to obtain the content of abdomen components of the detected person; meanwhile, in the process of measuring the bioelectrical impedance of the abdomen of the human body, the accuracy of impedance data measurement is improved in a multi-frequency detection and self-correction mode, and experimental results show that the error of a measured value of the abdomen of the human body can be controlled within 10%. In addition, compared with doctors and common large-scale human body composition analyzers and abdominal fat analyzers, the device has the advantages of higher pertinence, smaller size, noninvasive property, safety, simplicity, convenience and low cost, so that the product is a feasible solution for current household detection.

Description

technical field [0001] The invention relates to the technical field of analysis instruments, in particular to an abdominal component analyzer and an analysis method thereof. Background technique [0002] With the gradual improvement of people's living standards, obesity has become a serious problem in modern society, especially people with abdominal obesity are prone to arteriosclerosis, fatigue, abdominal distension, indigestion, poor spirits, poor sleep quality, high blood pressure, Hyperlipidemia, diabetes, fatty liver, coronary heart disease and other cardiovascular and cerebrovascular diseases, what's more, develop into many serious diseases such as myocardial infarction, cerebral infarction, stroke, hemiplegia, and liver cirrhosis. To this end, it is necessary to use professional instruments and equipment to detect and analyze the composition of the human abdomen, so that people can understand the development of their own physical fitness. [0003] Since a balanced an...
