Description

The present invention relates to a poultice, and particularly to a nano-thin film medicated poultice using a gel layer containing a medicinal component.

Conventional medicated compresses are constructed by coating an adhesive layer into a single layer and covering the adhesive layer with a single release film. The above-mentioned adhesive layer contains two components, an adhesive and an essential oil, and the essential oil is extracted from Chinese herbs. Therefore, the medicinal compress can be applied to the skin outside the human body and has the herbal effect of Chinese herbs.

Conventional medicated compresses have the following drawbacks.
First, the essential oil is volatile and dissipates, shortening the expiration date of the medicated compress and deteriorating its effect.
Next, the thick layer is difficult to stick to the surface of the skin and can be rolled up or peeled off. In particular, the compress attached to the joint part is easier to come off and peel off.
In addition, the adhesive layer comes into contact with the skin, helping it absorb the herbal extracts. Essential oils, on the other hand, can cause skin irritation and, in severe cases, can hurt the skin.
Therefore, it is an object of the present invention to improve the defective structure of the conventional medicated compress as described above.

The problem to be solved by the present invention is to provide a nano-thin film medicated compress that solves the shortcomings in the structure of the conventional medicated compress.

The main purpose of the nano-thin film medicated compress of the present invention is to adopt a gel layer to bring out the effects of crude drugs and prevent skin irritation.
The gel layer was created by Moghania philippinensis 35-40%, Toki 4-7%, Yamana 4-7%, Frankincense 4-7%, Myrrh 4-7%, White ▲ ▼ (Byakushi) 4 ~ 7%, River ▲ Kyu ▼ (Senkyu) 4-7%, Hata ▲ Gyo ▼ (Jingyo) 4-7%, Keishi 4-7%, Myrrh (Engosaku) 4-7%, 9-7% of winter green oil and 4-7% of myrrh brain are ground into fine powder with a diameter of 65-100 nm and mixed / prepared. 90-94% of fine powder medicinal ingredients are hypoallergenic. A gel layer is formed by chemical cross-linking or physical cross-linking by mixing with polymer compounds 6 to 10 having adhesiveness.

A wet cloth having a gel layer is irradiated with ultraviolet rays by applying an ultraviolet curable adhesive between a thin sheet-like or thin thin elastic layer made of polyurethane (PU) or the like having flexibility and elasticity and the gel layer. By curing and forming an adhesive layer, the elastic layer and the gel layer are bonded together, and the outer surface of the gel layer is used as the adhesive surface of the wet cloth, and the outer surface of the elastic layer is used as the elastic surface of the wet cloth. Is formed by uniformly distributing pores having an average pore diameter of 200 to 300 nanometers to provide air permeability, and a wet cloth having a sticking surface and an elastic surface is produced.
The release film covering the poultice sticking surface covers the outside of the gel layer used as the poultice sticking surface.
The protective film that adheres to the stretchable surface of the compress adheres to the outside of the elastic layer used as the stretchable surface.

The nano-thin film medicated compress of the present invention is produced by the method as described above. The main purpose is to extend the expiration date of the compress, reduce the incidence of irritation, and effectively solve the drawbacks of the prior art by storing the nanostructure of the medicinal ingredient for a long time.

Therefore, the nano-thin film medicated poultice of the present invention includes a sticking surface and an elastic surface as the structure of the poultice. The gel layer contains a fine powder having a diameter of 65 to 100 nm, and the outside of the gel layer is used as a sticking surface of a compress. Further, the elastic layer is adhered to the inside of the gel layer, and the elastic layer is used as an elastic surface on the outside of the compress.
There is an adhesive layer between the elastic layer and the gel layer, and the adhesive layer is an ultraviolet curable adhesive layer.
The sticking surface has an adhesive layer that surrounds the gel layer around the gel layer, and the adhesive layer is formed by adhering to the elastic layer to adhere the compress to the affected area.

Further, the nano-thin film medicated compress of the present invention includes at least one release film and one protective film. The release film covers the sticking surface of the compress, and the protective film adheres to the stretchable surface of the compress. Further, the separation line divides the release film into a large area portion and a small area portion.

The nano-thin film medicated poultice of the present invention is not limited to the nano-thin film medicated poultice produced according to the above method, and the structure of the medicinal component composed of nano-sized fine powder can be stored for a long period of time by using the gel layer. It prolongs the expiration date of the compress, prevents skin irritation, or reduces the incidence of irritation, and effectively solves the drawbacks of the prior art.
In addition, since the elastic layer is breathable, has excellent waterproofness, and can be stretched and spread in multiple directions, the nano-thin film medicated compress of the present invention can firmly adhere to the skin of the human body, causing problems such as detachment and peeling. You don't have to worry about it.
