Embodiment 1

[0112] refer to figure 1 , figure 2 , image 3 , Figure 4 , Fig. 5, a kind of human body fat measuring device, comprises internal electrical impedance measuring mechanism 7, height measuring mechanism 2, body weight measuring mechanism 1, microprocessor, memory 8 and display device 3, described internal body electrical impedance measuring mechanism, height The measurement output terminals of the measuring mechanism 2 and the weight measuring mechanism 1 are connected to the microprocessor, and the microprocessor includes: an information reading module 24 for receiving biomedical electrical impedance measuring mechanism 7, height measuring mechanism 2, body weight measuring mechanism 1 output signal; the height calculation module 25 is used to calculate the height of the tester after receiving the signal of the height measurement mechanism; the weight calculation module 26 is used to calculate the body weight of the tester after receiving the signal of the weight measureme...

Embodiment 2

[0173] refer to figure 2 , image 3 , Figure 4 ,Figure 5, Figure 6 , Figure 7 , the present embodiment is another implementation of the fat measuring device. In order to further measure and analyze the impedance and fat mass of the upper chest Z_chest, the two sides Z_bodySide of the body, the diagonal direction Z_athwart of the body, and the abdomen Z_abdomen in the human body, in the present invention Decompose the comprehensive impedance Z_integration of the human body, as shown in formula (14), as shown in Figure 6 as shown,

[0174] Z_integration = (Z_chest, Z_bodySide, Z_athwart, Z_abdomen) (14)

[0175]Z_bodySide in formula (14) mainly reflects the side of the body, Z_athwart is the internal organs, Z_chest is the chest, Z_abdomen is the tissue impedance of the lower abdomen, and the integrated impedance Z_integration reflects the tissue impedance of the body. As an important indicator of health, that is, when judging the amount of body fat, the part of Z_che...

Abstract

A device for measuring the fat ratio of human body is composed of an internal impedance measuring unit consisting of 4 current applying electrodes, 4 voltage measuring electrodes, constant-current source and voltage measuring circuit, a body height measuring unit, a body weight measuring unit, a microprocessor for calculating the fat ratio, a memory and a display.

Description

(1) Technical field [0001] The invention belongs to the application of biomedical electrical impedance technology, electronic technology, information technology, statistical technology and information management technology in health management, and is mainly suitable for physical examination and health diagnosis in hospitals, nursing homes, families and other occasions, especially a human body Fat measuring device. (2) Background technology [0002] The World Watch Association found that among the 6 billion people in the world, the number of people who are obese due to eating too much has increased to 1.1 billion, which is almost equivalent to the number of people who are too thin due to nutritional deficiencies; according to the estimates of the US Food and Drug Administration, there are More than 50 million people are losing weight, accounting for about 40% of the total population. Since only 5% of those who successfully lose weight can maintain the weight loss results wit...
