Problems solved by technology
[0005] The currently published patents define visceral fat as the fat distributed in the abdominal cavity, but there is also fat in the thoracic cavity, and the current detection methods based on electrical impedance do not take into account the amount of fat in the thoracic cavity
In addition, using the electrical impedance method to detect visceral fat requires placing multiple electrodes on the body surface, which is inconvenient to operate and the test results are affected by the moisture in the body

Embodiment Construction
[0047] The present invention will be described below in conjunction with the accompanying drawings and specific implementations, but the present invention is not limited to the following embodiments.
[0048] figure 1 is a block diagram of a visceral fat measurement and calculation device according to an embodiment of the present invention.
[0049] The schematic diagram of the visceral fat measurement device is shown in figure 1 , The visceral fat measurement and calculation device 1 includes an input unit 2 , a calculation control unit 3 , an output unit 4 , a light emitting unit 5 , a light detection unit 6 , a signal processing unit 7 and a display unit 8 .
[0050] The calculation and control unit 2 outputs the control signal, and after being driven by the output unit 4, the light emitting unit 5 is controlled to emit light, which is incident on the part of the human body to be measured, and the reflected light is detected by the light detection unit 6, and the signal ...

The invention provides a visceral fat determination device and a detection method and belongs to the technical field of human body information measurement. The visceral fat determination device comprises an input unit, a calculation control unit, an output unit, a light-emitting unit, a light detection unit, a signal processing unit and a display unit. The calculation control unit is connected with the output unit, the signal processing unit, the input unit and the display unit respectively, the output unit is connected with the light-emitting unit and the signal processing unit, and the input unit is used for inputting human body measurement information. The calculation control unit outputs a control signal, is driven by the output unit and then controls the light-emitting unit to emit light, the light enters the position to be determined of the human body, reflected light is detected by the light detection unit, the signal processing unit performs amplification and filtering, and the calculation control unit calculates body fat mass, visceral fat mass and whole-body subcutaneous fat mass according to a set mathematic model. According to a calculation method, visceral fat mass is obtained by subtracting whole-body subcutaneous fat mass from the body fat mass. The visceral fat determination device is simple, accurate in determination and convenient to operate.
Description
technical field [0001] The invention relates to a detection method and device for measuring visceral fat according to near-infrared light and human body circumference, and belongs to the technical field of human body information measurement. Background technique [0002] Obesity can induce a variety of acute and chronic diseases, affect the quality of life, and shorten life expectancy. Among them, people with visceral fat obesity are more likely to suffer from diabetes, hypertension, arteriosclerosis, and ischemic cardiovascular and cerebrovascular diseases than those with subcutaneous fat obesity and normal weight. Therefore, the detection of visceral fat is of great significance. [0003] Computed tomography (CT), magnetic resonance imaging (MRI) and ultrasound can detect visceral fat more accurately, but they are not suitable for home use due to their large size, inconvenient operation, and high price. [0004] Electrical impedance method is a common, simple and conveni...
