Description

Technical Field

[0001] The present invention relates to the field of TPU film medicinal patches, and in particular to a TPU film substrate with micropores, manufactured through formula adjustment and processing technology, combined with a viscous body containing Chinese herbal ingredients to form a breathable, waterproof, and well-adhering medicinal patch, thereby solving the problems and deficiencies of existing patches in use. Background Art

[0002] The structural design of a typical medicinal patch is mainly to combine non-steroidal chemical agents with adhesive to form an adhesive coating, which is then coated on a cloth or non-woven fabric, and then a layer of release paper is attached to the surface of the adhesive coating to form a medicinal patch with therapeutic effects.

[0003] From the above-mentioned medicinal patch, because it is based on a non-steroidal chemical agent as the adhesive coating, although it is easily absorbed by the affected skin, its medicinal gas is easily volatilized, so the therapeutic effect of the medicinal patch is relatively short. In addition, the cloth or non-woven fabric is thick and lacks elasticity, so it is difficult to achieve a good adhesion effect when applied, especially on the affected parts of the human body such as shoulders, arms, neck, back and limb joints. It is even easy to curl up and fall off. In addition, it has poor breathability and is not waterproof. Therefore, after long-term application, the affected area is prone to redness, swelling, rash, allergies, etc. At the same time, it is easy to fall off when encountering sweat, which seriously affects its overall practical value. It is necessary to find ways to solve and improve it. Summary of the Invention

[0004] In view of the many problems of conventional medicinal patches, such as poor efficacy, difficulty in applying the patch, and poor comfort, the inventors have embarked on research and development and design. Based on their many years of experience and technology in related industries, they have developed the TPU film medicinal patch of the present invention.

[0005] To improve the problems of conventional medicinal patches, the present invention mainly adopts a TPU film with micropores made of thermoplastic polyurethane as a substrate, a layer of adhesive containing Chinese herbal ingredients is coated on the TPU film substrate, and a layer of release paper is then covered on the surface of the adhesive layer to form an isolation protection, thereby making the TPU film medicinal patch of the present invention.

[0006] The TPU film medicinal patch of the present invention is made by adjusting the formula of TPU thermoplastic polyurethane material and processing technology to have tiny pores in the TPU film substrate, so as to increase its breathability and block the transmission of liquid and moisture. In addition, the elasticity and softness of the TPU film can not only improve the adhesion of the patch, but also solve the problems of skin irritation, redness, swelling, rash, allergies, etc. on the affected area, making it more comfortable to use and not easy to fall off.

[0012] The structural composition, technical means and efficacy of the present invention are further described below with reference to the accompanying drawings and examples.

[0013] See also Figure 1-4 The TPU film medicinal patch of the present invention is mainly made of a TPU film (10) made of thermoplastic polyurethane as a base material. The TPU film (10) base material has tiny pores in its structure through the adjustment of the formula and the processing technology, thereby increasing the air permeability and preventing the transmission of liquid and moisture. At the same time, the material of the TPU film (10) has good elasticity and softness and can obtain better tensile ductility and conformability. The TPU film (10) also has good biocompatibility, which can ensure the safety and comfort of contact with human skin. Its structural strength and durability are also better than the base materials of existing medicinal patches. More importantly, the TPU film (10) is easy to manufacture. The invention has excellent controllability and can be customized to produce TPU films (10) with different elasticity, softness, breathability and waterproofness that meet different needs through formula ratio and processing technology. A layer of viscous body (20) containing Chinese herbal medicine ingredients is coated on the TPU film (10) substrate. The Chinese herbal medicine ingredients contained in the viscous body (20) are mainly root, and are processed by nanotechnology to have better permeability and be easily absorbed by the affected part. The Chinese herbal medicine ingredients have undergone various biological tests and safety tests to prevent them from causing adverse effects on the human body. Finally, a layer of release paper (30) is coated on the surface of the viscous body (20) to form isolation protection, thereby making the TPU film medicinal patch of the present invention;

[0014] The TPU film medicinal patch of the present invention, which is designed through the above-mentioned structural composition, not only achieves the soothing and therapeutic effects on the affected part of the user by utilizing the medicinal effects of the Chinese herbal medicine ingredients contained in its adhesive body (20), but also, through the elasticity and ductility of the TPU film (10) substrate, it can be completely adhered to the human body's shoulders, arms, neck, back and limb joints, etc., and can adapt to various activities such as stretching and bending of the human body without being easy to fall off, while improving the comfort of its application. At the same time, long-term application will not cause redness, swelling, rash, allergies and the like on the affected skin, effectively solving the problems and shortcomings of conventional medicinal patches;

[0015] In other words, the TPU film medicinal patch of the present invention can be directly applied to the affected part after the release paper (30) is torn off during use. The excellent elasticity and softness given by the TPU film (10) substrate can achieve a good and compliant covering effect when applied to any part of the human body. The patch can conform to the curves of various parts of the human body without the risk of warping or falling off. There is no problem even with the body's limbs and various movements. In addition, the structure of the TPU film (10) substrate has a large number of tiny pores, which gives it excellent air permeability and waterproofness, and can also prevent the affected part from redness, swelling, rash, allergies, etc. The overall comfort of use will be greatly improved. Combined with the nano and Chinese herbal medicine components contained in the adhesive body (20), the patch can provide the affected part with a better therapeutic effect, solving the shortcomings of the conventional medicinal patch.

[0016] In summary, the TPU film medicinal patch of the present invention has the following characteristics:

[0019] (3) Elasticity and softness: TPU thermoplastic polyurethane material has good elasticity and softness, and has high ductility, tensile strength, and fracture resistance. Therefore, the TPU film medicinal patch made from it can completely adhere to the human body's shoulders, arms, neck, back, and limb joints, and can adapt to the human body's stretching and bending movements, providing a comfortable covering experience;

[0020] (4) Breathability: TPU thermoplastic polyurethane material can be made into a microporous film patch with good breathability through formula adjustment and processing technology. It allows the heat and water vapor emitted by the human body to be dissipated through the film patch, thereby reducing the skin redness, rashes, allergies, etc. caused by moisture retention due to poor breathability;

[0021] (5) Waterproofness: TPU thermoplastic polyurethane material can be used to control the pore size of the microporous film through formula adjustment and pore processing technology to manufacture microporous film patches with certain waterproof properties, so that a waterproof barrier can be formed on the surface of the patch to achieve a waterproof effect that prevents liquid water from penetrating;

[0022] (6) Strength and durability: TPU thermoplastic polyurethane material has good strength and durability. It can withstand the pulling action of the human body under normal movement and still maintain the stability of the patch.

[0023] (7) Adjustability: The hardness and elasticity of TPU thermoplastic polyurethane materials can be adjusted through the formula ratio and pore structure control technology. The elasticity, softness, breathability, waterproofness and other properties of the patch can be customized according to product needs and application requirements, giving it practicality in use;

[0024] That is, the TPU film medicinal patch of the present invention utilizes TPU film as a base material, thereby resolving the problem of conventional patches using a cloth base material. This design not only provides improved breathability but also possesses waterproof properties. Furthermore, it provides a more conformable and comfortable application, providing a better user experience and more effective treatment of the affected area. Furthermore, it eliminates the redness, swelling, rash, and allergic reactions that may occur with prolonged application, thus providing a more practical and valuable product.

[0025] In summary, the TPU film medicinal patch of the present invention can significantly improve the breathability, waterproofness, conformability, and comfort of the patch, and can provide better therapeutic effects, effectively solving the many problems and shortcomings faced by conventional medicinal patches in use. Overall, it is truly an excellent and outstanding innovative design, and an invention patent application has been filed in accordance with the law.
