Description
Technical field the present invention relates to human-body biological impedance bioelectrical measurement and memory technology, relates in particular to the human body composition measuring apparatus and the measurement data storage processing method thereof of memory function.
Relation between background technology obesity and the human health status is paid close attention to by increasing people.Yet people but often enter important mistaken ideas to the understanding of obesity, exactly obesity index are weighed with body weight merely.In fact, the relation between a personal health and the body weight can show as, the body weight when perhaps he was still keeping one's late 30s even more than 20 year old in the time of more than 40 year old, but intravital fat content may be different fully.
Therefore, obesity rapidly usually occurs in a short time, though body weight loses growth, health status is not good situation.Body weight meeting " bounce-back " also was based on this reason after some fat-reducing personage lost weight: what cut is body weight, rather than fat.So the fat situation of human body not only will also will be considered the intravital various component contents of people with reference to the body weight index.
The human body composition comprises muscle, skeleton, fat and other materials.From the circuit angle, tissue can simply be divided into moisture degrease matter and nonconducting not moisture lipid of conduction.Therefore, by detecting and analyzing the human body bio-electrical impedance, just can learn intravital each component content of people.
Prior art has a variety of by the human body bio-electrical impedance, calculates the device of component content in the human body again in conjunction with parameters such as body weight, height, age, sexes.Chinese patent ZL 00802193.7 discloses and has a kind ofly measured the device that the human-body biological electrical impedance is calculated body fat mass in human body content by two counter electrode, U.S. Pat 5,415, and 176 disclose a kind of device that can measure human body height and body slimming content simultaneously.
Yet, from angle biology, although the electrical impedance of each tissue keeps constant substantially in the human organ, but, comprise moisture, skin surface contact impedance etc. in food in the digestive tract and moisture, the body fluid by depending on multiple factor with the measured total impedance of a human body of human limb electrodes in contact.Therefore, above-mentioned the deficiencies in the prior art part just shows, even if reckon without same position testee, different resulting measurement data of period also can be different in one day, thereby the data that above-mentioned prior art measurement is obtained are limited to the directive significance of human health status assessment.
