Description

Technical Field

[0001] This utility model relates to the field of plaster technology, and in particular to a multi-layer breathable joint pain relief plaster. Background Technology

[0002] As a topical medication, medicated plasters primarily work through local penetration to relieve pain, reduce inflammation and pain, promote blood circulation, and relax muscles and tendons. They target pain in muscles and joints, reducing redness and swelling caused by inflammation, promoting local blood circulation, improving tissue oxygenation, and relieving muscle spasms. Medicated plasters are convenient to use, have a long-lasting effect, and provide a direct and effective treatment for many common pains, making them a commonly used adjunctive therapy in daily life.

[0003] Existing medicated plasters are convenient to use on flat areas such as the waist and back, but they tend to wrinkle when used on joints. The root cause is that the dynamic deformation of the skin caused by joint movement (including multi-directional stretching, folding and compression, and changes in three-dimensional curvature) does not match the static structure of the plaster (such as fixed size and shape, insufficient resistance to deformation of layered structures, and straight edge design). Since medicated plasters are designed as a single sheet, they cannot adapt to the different deformations of different parts of the joint, which further exacerbates this mismatch. This makes it difficult for the plaster to fit synchronously with the dynamic changes of the skin, ultimately leading to increased wrinkling. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a multi-layer breathable joint pain relief plaster.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer breathable joint quick pain relief plaster, the plaster comprising a first plaster body and a second plaster body, the first plaster body being integrally connected with a connecting strip, the connecting strip being rotatably connected to the two second plaster bodies via a rotating shaft, the ends of the second plaster bodies being arc-shaped, and an easy-tear line being provided between the two second plaster bodies, and a groove being provided at the bottom of the connecting strip.

[0006] As a further embodiment of this utility model, the plaster patch consists of, from top to bottom, a breathable non-woven fabric layer, a breathable sponge layer, a plaster layer, and a release paper.

[0007] As a further embodiment of this invention, the rotating shaft is made of medical-grade polypropylene or polyethylene.

[0008] As a further embodiment of this invention, the connecting band is made of elastic non-woven fabric or medical silicone material and has extensibility.

[0009] As a further embodiment of this invention, the plaster layers of the first and second ointments contain at least one analgesic ingredient selected from methyl salicylate, menthol, and camphor.

[0010] As a further embodiment of this utility model, the breathable sponge layer is an open-cell polyurethane foam with a thickness of 0.5-2mm.

[0011] As a further embodiment of this invention, the tear line is a laser pre-cut line or an indentation line, which facilitates the separation of the two No. 2 pastes.

[0012] This invention presents a multi-layered, breathable, quick-acting joint pain-relieving plaster. Its advantages lie in two aspects: First, regarding coverage and targeted treatment, the first plaster layer is generally applied to a flat surface of the body. When used on a joint, the second plaster layer can be rotated to adjust its application direction, allowing both layers to precisely cover different painful areas of the joint, improving the targeted efficacy and enabling the analgesic ingredients to act more effectively on the affected area. Second, considering skin breathability, if the plaster were made as a single sheet, covering a large area of ​​joints and other areas, it would severely impair skin respiration. The separate design of this invention reduces the continuity of skin coverage, helping to maintain normal skin breathability and reducing the probability of discomfort such as redness, itching, and allergies caused by poor breathability. Furthermore, in terms of ease of movement, joints are frequently used. If the plaster is applied as a single piece and covers a large area, it is easy to cause wrinkles and tightness when the joint is in motion, which restricts the range of motion. The separate plaster design allows each part of the plaster to be relatively independent when the joint is in motion, reducing the restriction on joint movement, preventing wrinkles, and allowing users to move their joints more freely while applying the plaster.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this utility model, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0020] A multi-layer breathable joint pain-relieving plaster includes a first plaster body 1 and two plaster bodies 4. The first plaster body 1 is integrally connected to a connecting band 2. The connecting band 2 is rotatably connected to the two second plaster bodies 4 via a rotating shaft 3. The ends of the second plaster bodies 4 are arc-shaped, and an easy-tear line 5 is provided between the two second plaster bodies 4. The easy-tear line 5 is a laser pre-cut line or an indentation line to facilitate the separation of the two second plaster bodies 4. The bottom of the connecting band 2 is provided with a groove 6. When the pain is located on both sides of the joint, the two connected second plaster bodies 4 can be separated along the easy-tear line 5 using the designed detachable plaster. Then, the two second plaster bodies 4 can be manually rotated in opposite directions. The groove 6 provides space for the second plaster bodies 4 to rotate. After rotation, the second plaster bodies 4 can be applied to the painful areas on both sides. The detachable design is more convenient for flexible use at different pain locations compared to the integral design.

[0021] Furthermore, the plaster consists of, from top to bottom, a breathable non-woven fabric layer 7, a breathable sponge layer 8, a plaster layer 9, and release paper 10. The breathable non-woven fabric layer 7 provides protection and allows breathability through the gaps between the fibers of the material itself. It reduces direct irritation to the skin and wound from external factors, lowers the risk of infection, and allows air circulation. The breathable sponge layer 8 is an open-cell polyurethane foam with pores and a thickness of 0.5-2mm. Its function is to further enhance breathability. Its open-cell structure facilitates gas exchange and moisture evaporation, while also providing some cushioning and support, allowing the plaster to better adhere to the skin. After absorbing a small amount of moisture from the skin surface, it maintains a certain degree of breathability, allowing the skin to "breathe" and improving the overall user experience.

[0022] In the next step, the rotating shaft 3 is made of medical-grade polypropylene or polyethylene material, and the connecting belt 2 is made of elastic non-woven fabric or medical silicone material with extensibility.

[0023] In addition, the plaster layer 9 of the first plaster 1 and the second plaster 4 contains at least one analgesic ingredient selected from methyl salicylate, menthol, and camphor.

[0024] It should be noted that changing the straight edges of the plaster to curved edges, combined with the separate design of the plaster in this case, improves its anti-wrinkle performance. During human activity, the skin stretches and contracts. Straight edges, especially at joints and other areas with high range of motion, tend to make "hard contact" with the skin, causing wrinkles at corners due to stretching. Curved edges conform to the skin's curvature, reducing "resistive stretching" and lowering the probability of edge lifting and central wrinkling. From a stress distribution perspective, the endpoints of straight edges are stress concentration points, where the material is easily compressed and wrinkled under stress. The curved structure of the curved edges evenly distributes stress, preventing excessive stress at a single point and maintaining stable adhesion.

[0025] Working principle: When using the plaster, peel off the release paper 10 at the bottom of plaster 1, and then apply plaster 1 to the painful area. Plaster 1 is generally applied to a flat surface of the body. When used on a joint, the rotating shaft 3 allows you to rotate plaster 4 to adjust the application direction. Position plaster 4 against the joint, then peel off the release paper 10 at the bottom of plaster 4 to expose the plaster layer 9. Finally, apply plaster 4 to the joint. This separation prevents the joint from being covered by a large area and becoming airtight.

[0026] Additionally, when the pain is located on both sides of the joint, the designed detachable plaster allows the two connected plaster pieces 4 to be separated along the tear line 5. The two plaster pieces 4 can then be manually rotated in opposite directions. The groove 6 provides space for the rotation of the plaster pieces 4. After rotation, the plaster pieces 4 can be applied to the painful areas on both sides. This detachable design, compared to a one-piece design, facilitates flexible use for different pain locations.

[0027] The breathable nonwoven fabric layer 7 mainly serves a protective function, achieving breathability through the gaps between the fibers of the material itself. It can reduce direct external stimulation to the skin and wounds, reduce the risk of infection, and allow air circulation to keep the skin surface dry, which helps to improve the user's comfort. It can also absorb the heat exhaled by the skin to a certain extent and transport it outward. The breathable sponge layer (8) is an open-cell polyurethane foam with a thickness of 0.5-2mm and distributed with breathable pores (pore diameter 0.2-0.5mm). Its function is to further enhance breathability. Its open-cell structure helps gas exchange and moisture evaporation, while also providing a certain amount of cushioning and support, so that the plaster can better fit the skin. After absorbing a small amount of moisture from the skin surface, it maintains a certain degree of breathability, allowing the skin to "breathe" and improving the overall user experience.

[0028] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
