Background technique

The effect of far infrared rays has been discovered for more than 50 years since its discovery. It is known from known clinical experiments that far infrared rays can penetrate the inside of the human body and generate heat from the inside of the human body. Not only can it promote the expansion of human microvessels, make the human blood circulation smooth and promote metabolism, but also have the health care effect of soothing pain and Can increase the body's immunity and treatment rate.

Although some manufacturers have adopted silica gel as the carrier of far-infrared powder, in order to increase the content of far-infrared powder and increase the coverage of far-infrared powder, a better far-infrared radiation effect can be produced. However, their finished product has not been made into a structure that is easy to use and easy to attach to the human body, but must be passed through an external band or bandage to be attached to the human body, causing inconvenience in use. For example, the patent shown in Taiwan ’s invention announcement No. 362981 “Energy silicone patch, gasket and its manufacturing method” claims that it can increase the proportion of far infrared powder content to 50 to 65% to increase the irradiance. However, the patch made by it has no adhesive layer and release paper design. It must be attached to the human body through an external band or bandage, which is extremely inconvenient to use. Therefore, it has not been made into a patch product with a sandwich structure formed by a patch plus an adhesive layer and a release paper. If it is to be made to contain an adhesive layer and a release paper, it must overcome the adhesive layer How to effectively combine the problem of patch and release paper must overcome the problems that the solvent contained in the adhesive layer will cause human skin allergies and health hazards. These problems have been completely overcome by the inventors after a long period of research and testing.

Furthermore, the known patches for soothing pain are mostly coated with a layer of medicinal materials on a substrate made of gauze or non-woven fabric, and a piece of release paper is added to the layer of medicinal materials. When in use, tear off the release paper, apply the base sheet and the medicinal material layer to the affected part of the human body, and infiltrate the human body through the medicinal effect of the medicinal material layer, so as to achieve the purpose of soothing the pain. However, it is a sore and soothing effect due to the medicinal effect of the medicinal materials, not a physical therapeutic effect, and the medicinal material layer is coated on the gauze or non-woven substrate. Because the gauze or non-woven fabric has a breathable effect, it will make Part of the medicinal effect will dissipate from the other side of the gauze sheet, so that not only reduces the soothing effect of soreness and pain, but also spreads the nose outside the medicine, which is more likely to cause discomfort. Therefore, this known technology is indeed not perfect, and there is still a need for further improvement. In addition, patches commonly used for medicinal materials and release paper cannot be mixed with functional materials such as far-infrared materials on gauze or non-woven fabrics. If only far-infrared functional materials are coated on the surface of gauze or non-woven fabrics, far-infrared The content of the material is not enough to achieve an effective far-infrared physiotherapy effect. The reason is that the present inventors have been working hard to develop, and finally developed a set of the present invention that is different from the above-mentioned known technology.
