Description

Portable body fat analyzer {fat measuring apparatus for portable}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body fat analyzer, and in particular, a portable body fat analyzer that enables the measurement of body fat of human components through bioelectrical impedance analysis (BIA) with the thumb contact of both hands is easy and convenient anytime, anywhere. The present invention relates to a portable body fat analyzer, which enables to measure the body fat of a subject quickly, as well as to facilitate the use of the body fat analyzer of the subject.

In general, the human body is composed of water, protein, bone and fat, except for a small amount of components, the sum of which is the weight.

The ratio of fat to body weight is called body fat and is used as an indicator of the slimness of the body, and is also used to diagnose various adult diseases.

Medically, components other than fat, ie, muscle mass, are components that maintain the function of the body.

Patients who are nutritionally related, such as cancer patients or dialysis patients, can measure the amount of muscle in their bodies periodically to advance the rate of disease progression or therapeutic effects.

Even when obese people exercise to lose weight, there is little change in body weight during the relatively short exercise period of several months.

In this case, even if the body composition is measured, the amount of fat in the body decreases but the amount of muscle increases. Therefore, the effect of exercise can be understood more scientifically.

In addition, the measurement of human components can progress the growth and development of children or nutritional status of the elderly, especially in the case of various patients can be used as an important method for the diagnosis of patients by measuring the distribution of water according to the parts of the human body. .

That is, the body fat analyzer refers to applying an electrical signal to the human body while receiving personal data of a subject (eg, height, weight, age, and gender).

This means that the more muscles a person has, the higher the water content in the human body and the higher the water content, the easier the current flows to the body.

However, the conventional body fat analyzer provided for the measurement of the human body components as described above has a disadvantage in that the measurement of the body fat of the subject is in place because it is a stationary machine rather than a portable device.

That is, the conventional body fat analyzer has four contact parts having electrodes, and receives the personal data information (eg, height, weight, age, and gender) of the subject, and at the same time, both hands and both feet must be contacted. (For example, in the form of a treadmill), the body fat cannot be measured while carrying it, and the measurement is made at the visit of the subject while being fixed in one place.

Accordingly, an object of the present invention is to solve the conventional problems as described above, the object of the present invention, the portable body fat to enable the body fat measurement of the body components through the bioelectrical impedance analysis (BIA) to the thumb contact of both hands By configuring the measuring device, it is free to move so that you can easily and quickly measure the body fat of the subject anytime, anywhere, as well as to make it easier to use the body fat measuring instrument.
