Description

technical field [0001] The invention relates to the technical field of biometrics, in particular to a bioelectrical impedance measuring device for multi-point sampling cross correction. Background technique [0002] With the continuous development of biotechnology, bioelectrical impedance technology is gradually appearing in front of people. Bioelectrical impedance measurement is a method of extracting biomedical information related to human physiological and pathological conditions by using the electrical characteristics of biological tissues and organs and their changing laws. Detection Technology. It usually uses an electrode system placed on the body surface to send a small AC measurement current or voltage to the test object to detect the corresponding electrical impedance and its changes, and then obtain relevant physiological and pathological information according to different application purposes. It has the characteristics of non-invasive, harmless, cheap, simple o...

Problems solved by technology

[0003] However, the data measured by the current bioelectrical impedance measurement device is too simple, and due to the different body shapes of people, it often causes large deviations in the detection results. At the same time, various postures of creatures also have accompanying changes in bioelectrical impedance , and such data cannot be measured by traditional measuring instruments. At the same time, in some special cases, when some contact motors with the patient or the person being tested fall off, have poor contact, or are damaged, the measured data will appear extremely Earth deviation, which will directly affect the operator's analysis results of these current information, if the operation is not done properly, it will cause irreparable damage
