Description

Technical Field

[0001] This utility model relates to the technical field of medical bandages, and in particular to a self-adhesive elastic bandage. Background Technology

[0002] Medical bandages are materials used for medical purposes, primarily to protect and immobilize wounds, support injured joints or muscles, and promote healing. They are typically made of cotton, elastic materials, or synthetic fibers and come in different widths and lengths to accommodate various injuries.

[0003] Bandages can help control bleeding, reduce swelling, restrict movement, and prevent further injury. Depending on the specific need, bandages can be categorized into different types, such as compression bandages, elastic bandages, and stabilizing bandages. Compression bandages are typically used to control bleeding after injury, while elastic bandages are used to support sprains or strains.

[0004] When using bandages, ensure proper bandaging to prevent obstruction of blood circulation and keep the wound clean. If the wound is large or severe, seek medical attention promptly. Medical bandages are an important tool in modern medicine, and their correct use can significantly accelerate the wound healing process.

[0005] Related technology can be found in Chinese Patent CN102462585A, which discloses a bandage. This bandage consists of a male- or female-female Velcro fastener fixed to both ends of a cloth strip. A sliding buckle is located on the back of the air bladder, through which the cloth strip passes, securing the air bladder to the cloth strip. The air bladder nozzle is fixed to the outside of the air bladder. The inflatable air bladder is an independent component; after connecting the inflatable air bladder to the nozzle, air can be injected into it. In use, the cloth strip is roughly wrapped around the wound, the air bladder is slid directly above the wound, and the air bladder is inflated to effectively compress the wound. This method is suitable for bandaging and stopping bleeding from wounds in the groin area, femoral artery, armpit, or other more complex locations, and it has ideal effects on bandaging special wound sites.

[0006] However, the above solution has certain shortcomings, mainly in that the front and back sides of the bandage rely on fixed female or male Velcro fasteners for fixation. This design is prone to the Velcro fasteners falling off, thus reducing the stability of the bandage. Therefore, a self-adhesive elastic bandage is proposed to solve the above technical problems. Utility Model Content

[0007] This application provides a self-adhesive elastic bandage that improves the stability of the bandage.

[0008] This application provides a self-adhesive elastic bandage, which adopts the following technical solution:

[0009] A self-adhesive elastic bandage includes a non-woven fabric layer, on which a napped surface and an adhesive surface are provided. A plurality of pleats are formed on the napped surface of the non-woven fabric layer, and a plurality of first hook-shaped loops are provided on the pleats of the non-woven fabric layer. A plurality of rows of dot-shaped protrusions are provided on the adhesive surface of the non-woven fabric layer, and loops matching the first hook-shaped loops are provided on the dot-shaped protrusions.

[0010] By adopting the above technical solution, the self-adhesive elastic bandage, through the design of dotted protrusions on its adhesive surface, ensures excellent adhesion performance when in contact with the target surface. In addition, the first hook-shaped loop on the napped surface of the bandage can interlock with the loops on the dotted protrusions. This hook-loop structure effectively enhances the adhesion of the bandage, and the interaction between the hook and loop creates a self-adhesive effect. This not only improves the stability of the bandage but also ensures its long-term fixation effect during use.

[0011] Preferably, the cross-section of the dot-shaped protrusions is circular, and the several rows of dot-shaped protrusions are distributed in a matrix.

[0012] By adopting the above technical solution, the circular cross-section design can effectively increase the contact area with the contact surface, thereby significantly improving grip or friction. In addition, the multiple matrix-arranged dot-shaped protrusions can evenly distribute the pressure applied to them, avoiding the concentration of local pressure. This dispersion measure helps to reduce the discomfort and potential damage risk caused by local pressure.

[0013] Preferably, the nonwoven fabric layer has an extension layer on its bonding surface, and the extension layer is provided in a plurality of places, with the extension layer and the plurality of rows of dot-shaped protrusions arranged alternately.

[0014] By adopting the above technical solution, the interval design effectively disperses the force applied to the extension layer; during use, the synergistic effect between the extension layer and the dotted protrusions allows the pressure to be distributed more evenly, thereby improving the overall performance.

[0015] Preferably, the extended layer is elongated and has V-shaped corners.

[0016] By adopting the above technical solution, the V-shaped corner design can significantly improve the material's adaptability when the extension layer is stretched or bent, thereby reducing the risk of cracking or breakage during use; the V-shaped corner adapts more effectively to the body's natural curves, especially at joints, thus improving wearing comfort; in addition, the V-shaped corner structure can reduce the possibility of material damage during folding or stretching, thereby extending the product's service life.

[0017] Preferably, a transparent anti-stick layer is provided on the adhesive surface of the nonwoven fabric layer.

[0018] By adopting the above technical solution, the transparent anti-adhesion layer effectively prevents the non-woven fabric layer from sticking to other surfaces during storage or transportation, thereby maintaining its structural integrity and functionality.

[0019] Preferably, the nonwoven fabric layer has a plurality of dotted tear sections at equal intervals.

[0020] By adopting the above technical solution, the dotted tear line design makes the bandage easy to tear when needed, allowing users to quickly obtain the required bandage length. This design enables users to easily and quickly adjust the bandage length without the need for tools such as scissors, thus significantly improving ease of use.

[0021] Preferably, a colored anti-adhesive layer is provided on the adhesive surface of the nonwoven fabric layer and along the dotted tear portion, and the colored anti-adhesive layer is located between the adhesive surface of the nonwoven fabric layer and the transparent anti-adhesive layer.

[0022] By adopting the above technical solution, the design of the colored anti-adhesive layer is intended to help users quickly identify the dotted line tear section; its color contrasts sharply with the non-woven fabric layer and the transparent anti-adhesive layer, enabling users to quickly locate the tear section and reduce the time required for searching and operation.

[0023] In summary, this application has the following beneficial effects:

[0024] 1. The self-adhesive elastic bandage features a dotted raised structure on its adhesive surface, ensuring excellent adhesion when in contact with the target surface. Furthermore, the first hook-shaped loop on the napped surface of the bandage engages with the loops on the dotted raised areas. This hook-loop structure effectively enhances the bandage's adhesion, creating a self-adhesive effect through the interaction between the hook and loop. This not only improves the bandage's stability but also ensures its long-term fixation during use.

[0025] 2. By incorporating an extension layer, the V-shaped corner design significantly enhances the material's adaptability when stretched or bent, thereby reducing the risk of cracking or breakage during use. This V-shaped corner more effectively conforms to the body's natural curves, especially at joints, thus improving wearing comfort. Furthermore, the V-shaped corner structure reduces the likelihood of material damage during folding or stretching, thereby extending the product's lifespan. Attached Figure Description

[0029] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0030] This utility model discloses a self-adhesive elastic bandage, which is wound onto a take-up drum 1, such as... Figure 1 As shown, it includes a non-woven fabric layer 5, on which a napped surface 2 and an adhesive surface 3 are provided. Several pleats are formed on the napped surface 2 of the non-woven fabric layer 5, and several first hook-shaped loops are provided on the pleats of the non-woven fabric layer 5. Several rows of dot-shaped protrusions 4 are provided on the adhesive surface 3 of the non-woven fabric layer 5, and loops matching the first hook-shaped loops are provided on the dot-shaped protrusions 4.

[0031] like Figure 1 As shown, the self-adhesive elastic bandage has dotted protrusions 4 on its adhesive surface 3, which allows the bandage to form good adhesion when it comes into contact with the target surface. On the napped surface 2 of the bandage, the first hook-shaped loop can interlock with the loop on the dotted protrusions 4. This hook-loop structure increases the adhesion of the bandage. Through the interaction between the hook and the loop, a self-adhesive effect is formed, which further enhances the stability of the bandage during use and its long-term fixation effect.

[0032] like Figure 1 As shown, the terry loop side fits against the target surface, and the breathable terry loop structure allows air to circulate freely between the bandage and the skin, avoiding a stuffy and humid environment, thereby reducing user discomfort; this is especially important for wearing bandages for extended periods or during exercise; a breathable bandage can effectively wick away sweat, keep dry, and provide sufficient flexibility, allowing users to move freely during exercise without feeling restricted, thus improving athletic performance.

[0033] like Figure 1 As shown, the elasticity of the non-woven layer 5 allows the bandage to adapt to different body parts and remain comfortable during exercise or physical activity without causing a feeling of restriction; at the same time, the pleated design also provides the bandage with greater extensibility.

[0034] like Figure 1As shown, due to the synergistic effect of the self-adhesive and hook-and-loop structure, the bandage can provide a more secure effect when fixing temporary wounds or protecting areas, preventing the bandage from slipping.

[0035] like Figure 1 As shown, the material of the 5 pleats of the non-woven layer is spandex. Spandex has extremely high elasticity and can be stretched to several times its original length without deformation; this allows the hook ring to adapt well to various shapes and sizes during use, providing a good fit.

[0036] like Figure 2 As shown, the dot-shaped protrusions 4 have a circular cross-section, which effectively increases the contact area with the contact surface, thus providing better grip or friction. Several rows of dot-shaped protrusions 4 are arranged in a matrix, effectively helping to evenly distribute the pressure applied to them, avoiding concentration at a single point, thereby reducing discomfort or injury risks caused by localized pressure. The dot-shaped protrusions 4 have a porous structure, which creates gaps within the structure, forming airflow channels and enhancing breathability and drainage. Furthermore, the dot-shaped protrusions 4 are made of one of the following materials: natural rubber, natural latex, or polyisoprene latex, providing excellent elasticity, comfort, and durability, while also improving the overall user experience through their breathability and antibacterial properties. These advantages make the product suitable for various applications, such as sports equipment, medical supplies, and daily necessities.

[0037] like Figure 2 As shown, an extension layer 6 is provided on the adhesive surface 3 of the nonwoven fabric layer 5. Several extension layers 6 are provided, and the extension layers 6 and several rows of dot-shaped protrusions 4 are arranged alternately. The arrangement of the extension layers 6 and the spacing of the dot-shaped protrusions 4 form a special structure that can provide better adaptability and flexibility during the bonding process. Due to the spaced design, the force applied to the extension layers 6 can be more effectively distributed. During use, the extension layers 6 and the dot-shaped protrusions 4 work together to distribute the pressure more evenly, thereby improving the performance.

[0038] like Figure 2 As shown, specifically, the extension layer 6 is elongated, providing a certain degree of linear extensibility. The extension layer 6 also features V-shaped corners 7. When the extension layer 6 is stretched or bent, the V-shaped corners 7 offer better adaptability, preventing the material from easily cracking or breaking during use. The V-shaped corners 7 design better conforms to the body's natural curves, especially at joints, improving wearing comfort. Furthermore, the V-shaped corners 7 reduce the likelihood of material damage during folding or stretching, thereby extending the product's lifespan.

[0039] like Figure 2As shown, the material of the stretch layer 6 is spandex; the molecular structure of spandex gives it excellent elasticity, enabling it to maintain its shape and quickly return to its original state when stretched; this property ensures that the stretch layer 6 does not lose its original shape after repeated stretching and compression; spandex fibers can stretch to several times their original length without breaking, thus effectively adapting to the body's movements in various sports and body posture changes; moreover, spandex materials are generally lightweight and breathable, providing a comfortable wearing experience, promoting air circulation, and reducing moisture accumulation.

[0040] like Figure 2 As shown, a transparent anti-adhesive layer 8 is provided on the adhesive surface 3 of the non-woven fabric layer 5; the transparent anti-adhesive layer 8 can effectively prevent the non-woven fabric layer 5 from sticking to other surfaces during storage or transportation, maintaining its integrity and functionality; during use, the user can more easily peel off the anti-adhesive layer to ensure that the adhesive surface 3 remains clean, facilitating better bonding with the target surface.

[0041] like Figure 2 As shown, the self-adhesive elastic bandage has several dotted tear sections 9 evenly spaced on it. The dotted tear sections 9 make the bandage easier to tear when needed, and users can quickly obtain the required bandage segment according to the required length. Users do not need to use tools such as scissors. The tearing function can be used to conveniently and quickly adjust the length of the bandage, improving the convenience of use.

[0042] like Figure 2 As shown, a colored anti-adhesive layer 10 is provided on the adhesive surface 3 of the nonwoven fabric layer 5 and along the dotted dotted tear portion 9. The colored anti-adhesive layer 10 is located between the adhesive surface 3 of the nonwoven fabric layer 5 and the transparent anti-adhesive layer 8. The colored anti-adhesive layer 10 is used to facilitate quick location of the dotted dotted tear portion 9. The color of the colored anti-adhesive layer 10 contrasts with the nonwoven fabric layer 5 and the transparent anti-adhesive layer 8, enabling users to quickly identify and locate the dotted dotted tear portion 9, reducing the time spent searching and operating.

[0043] Working principle: When using, the user first quickly finds the dotted tear 9 on the adhesive surface 3 of the nonwoven fabric layer 5 according to the position of the colored anti-adhesive layer 10, and then tears off the nonwoven fabric layer 5. Then, the adhesive surface 3 on the nonwoven fabric layer 5 is aligned with the affected area, and the nonwoven fabric layer 5 is stretched. Under the action of the stretching layer 6, the wrinkles on the nonwoven fabric layer 5 are stretched.

[0044] Then, by means of the first hook-shaped loop interlocking with the loops on the dotted protrusions, the hook-loop structure effectively enhances the adhesion of the bandage. The interaction between the hook and the loop creates a self-adhesive effect, which not only improves the stability of the bandage but also ensures its long-term fixation during use.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
