Human body composition analyzer

Abstract

The invention discloses a human body composition analyzer. The human body composition analyzer comprises a detecting electrode unit, a control device and an analysis device. The detection electrode unit is connected with the control device which is connected with the analysis device. The detection electrode unit makes contact with a human body and is used for outputting measurement current and collecting a detection signal, wherein the detection electrode unit can output measurement current at multiple frequencies. The control device is used for controlling the frequencies of the measurement current and receiving the detection signal. The control device sends the detection signal to the analysis device. The analysis device is used for analyzing the human body composition on the basis of the detection signal. The human body composition analyzer performs biological impedance measurement in a multi-frequency mode and can cover all frequencies needed for human extracellular composition and human intercellular composition, a measurement result can be more accurate, the advantages that electrode end contact impedance is eliminated, long-cable impedance is eliminated, and body weight measurement accuracy is improved are achieved, and more accurate living body composition data can be acquired.

Description

technical field [0001] The invention relates to the technical field of human body composition detection, in particular to a human body composition analyzer. Background technique [0002] The human body is composed of water, protein, fat and minerals. These four substances are the basic components of the human body. The balance between them is very important to health. A body composition analyzer is an instrument that uses the method of measuring bioelectrical impedance (BIA) to determine body composition. It uses a weak constant alternating current that cannot be felt by the human body, and connects the hands and feet of the human body with electrodes to measure the electrical impedance of each component of the human body. Fat in the human body is a non-conductor, while muscle has more water content and is an easy conductor. If there is more fat and less muscle, the biochemical resistance value will be relatively high when the current passes; otherwise, the biochemical resi...

Problems solved by technology

[0004] However, most traditional body composition analyzers use single-frequency measurements. Different frequencies have different effects on penetrating body fat and cell walls. If a single frequency is used, it is difficult for the current to penetrate the cell wall, and only the approximate extracellular water in the human body can be measured. and other ingredients

Moreover, the surface of the measuring motor will spontaneously form oxygen-containing compounds due to oxygen or air humidity in the atmosphere, which will affect the accuracy of the measurement
