Here, the elastic framework can be bent to adapt to different body shapes or portions and adjusted to provide most comfortable wearing angle, so that a proper air flowing can be achieved between the skin or the body portion and the clothes, thereby keeping the skin dry.

## Background
FIELD OF THE INVENTION
The present invention is related to a three-dimensional elastic framework, which can form a space between cloth and skin for allowing ventilation and heat dispersing.
BACKGROUND OF THE INVENTION
Generally, a cover or cloth located on the skin for allowing ventilation and heat dispersing is mainly focused on separating the affected part from the underclothes.
Take the cover for separating the affected part as an example. A swab or breathable cotton is always used to cover on the affected part. However, when the user washes his/her hand or sweats, the swab or breathable cotton might absorb water or sweat easily which actually provides a great environment for bacteria proliferation and causes a secondary affection. Besides, when the cover absorbs water, it becomes non-breathable, so that it is difficult for the affected part to stay dry, and even, the new grown tissue might be stuck by the cover which will destroy the tissue as exchanging the cover, and of course, extend the recovering period.
Moreover, modern people often wear adjustable underwear or clothes capable of modifying body shape which always tightly constricts the skin, so that it is very easily to become muggy and wet. Therefore, this kind of clothes always utilizes special knitting manner or introduces thereinto a material with high thermal conductivity for achieving greater ventilation or heat dispersing capability.
When utilizing the specific knitting method for increasing ventilation, such as, by track and column braiding and lattice braiding, the increased spaces for ventilation are only the intervals among lines which are extremely small and only located on the surface of textile fabrics, and even the liner material is selected to be breathable or meshed, the skin, the liner material and the outer cloth still keep close together, so that the discomfort caused from muggy and sweat still exist.
When introducing materials with high thermal conductivity into knitting, only the body temperature can be dispersed, and since human body achieves heat dispersing mainly through sweating, if it can not provide sufficient space for ventilation, the feeling of muggy still can not be effectively reduced.
Therefore, no matter the cover placed on the affected part or the clothes worn on the skin, after a long time attachment to the skin, it might easily cause a humid and muggy environment which actually encourages the growth of bacteria and fungi, so as to further influence health and sanitation.
SUMMARY OF THE INVENTION
Skin is the outermost protection for organisms and the basic principle for taking care of skin is to keep the skin dry and breathing freely, especially for the injured skin, like cuts or wounds. However, the modern people chase for perfect body shape through wearing adjustable skin-tight clothes and disregard of ventilation. Therefore, the present invention provides a 3D ventilation device for separating the skin from the clothes, so as to maintain the ventilation space therebetween, thereby reducing the burden on the skin.
The present invention is related to a 3D ventilation device for separating body skin from clothes, in which the separation is achieved by a 3D elastic framework, which can be made of elastic hard polymer or bent metal lines covered by soft material such as cloth or sponge, so as to provide supportability and also adaptation to different body shapes or body portions, thereby it can be adjusted to most comfortable wearing angle. The elastic framework can form a separated space for propping up the clothes so as to provide the air flowing space between the skin or body portion and the clothes and thus to keep the skin dry.
When the present invention is applied to daily life, through the elastic framework covering the skin or organ and propping up the clothes to provide great ventilation, the uncomfortable muggy feeling can be reduced, so as to eliminate the causes of skin diseases, such as high temperature and sweat humidity. Especially for woman's breast and man's testicle which are always covered by tight underwear, the present invention can prevent a direct contact between the organ and the clothes, so as to reduce the burden on the skin and rubbings against the clothes and also increase the buffer of compression.
Besides, when the present invention is applied to medical purposes, through the elastic framework covering around the affected part and the interior lines of the elastic framework propping up the clothes, it can prevent the affected part from rubbing against the clothes or sticking on contaminants which might cause inflammation and infection. And, owing to the separated space, the external medicine can be fixed or great ventilation can be provided without contacting the affected part, and further, the clothes will not be stained or will not influence the new grown tissue, thereby facilitating the recovery.
