Description

Skin thickness measuring device and skin thickness measuring method using the device {Apparatus and Method for Measuring Thickness of skin}

The present invention relates to a skin thickness measuring device and a method for measuring skin thickness using the skin thickness measuring device. More particularly, the present invention relates to an apparatus and a method for measuring the thickness of the skin by lifting the skin between the first roller and the second roller to measure an angle of change of the encoder.

Generally, skin is divided into epidermic and dermis, which include the stratum corneum. The epidermal layer covers the outermost part of the human body and plays an important role in preventing roughness and fine lines of the skin by preventing foreign substances from invading from the outside or preventing evaporation of moisture in the body.

The dermal layer is located under the epidermal layer and determines the elasticity of the skin. The elasticity of the skin is achieved when collagen, an collagen fiber, and elastin, an elastic fiber, contained in the dermis are functioning normally. Damage to or elastin can lead to skin aging.

Meridian in oriental medicine is a constant reaction system line of the blood circulation in the human body. A phenomenal reaction line in which the reaction is expressed in the body surface with the correlation between the five intestines and the skin inside is called Meridian. The response point is called acupuncture points. Thus, if there is a disease in the viscera, the meridians affect the body, and the meridians of the body surface reflect the abnormal function of the books.

Thus, in general, a skin resistance meter for analyzing the human condition by measuring the skin resistance at the point where the state of the meridians in the acupuncture points of the meridians of the human body on average is well used. On the other hand, meditation medicine is a traditional constitution medicine that classifies people according to their constitution characteristics and thus diagnoses and treats diseases.

Constitution refers to the characteristics of the body born from birth, it is classified according to the appearance and personality of the person, depending on the thickness and elasticity of the person's ideological constitution may be classified. Regarding the classification of Taeumin, the thickness of the skin is the thickest, and the noise is thinner than Taeinin, but thicker than Soyangin.

In oriental medicine, in the classification of the constitution according to the skin condition, the constitution is classified by the color of the skin or the thickness and elasticity of the skin. By the way, the conventional measurement of skin thickness and elasticity in oriental medicine has a disadvantage in that accuracy and objectivity are lacking since the oriental medicine measures the thickness or elasticity while directly grabbing or pulling the subject's skin.

1 is a view illustrating a measure of the thickness of the skin while the oriental doctor directly grabbing or pulling the subject's skin. 2 shows a schematic diagram of a conventional skin thickness measurement system 10. As shown in FIG. 2, the skin is sucked up between the two rollers 11 while the two rollers 11 rotate in opposite directions by the motor driving unit 12. Therefore, the micro-displacement angle control unit 13 measures the displacement angle α, which changes according to the degree of skin curling, to measure the relative skin thickness.

However, in the case of such a conventional skin thickness measuring device, when the frictional force between the roller and the skin is weak, there is a problem that the skin slips between the rollers. Displacement angle also does not increase linearly with the thickness of the skin, there was a disadvantage in lack of accuracy and objectivity. Therefore, there is a need for a skin thickness measuring apparatus and measuring method which can be improved and measured accurately.
