Description

Technical Field

[0001] This utility model belongs to the field of hygiene products technology, specifically relating to a medical elastic bandage. Background Technology

[0002] Medical bandages are gauze bandages used to wrap wounds and affected areas, primarily for surgical injuries, sprains, post-operative bandaging, and immobilization. They come in various types, including self-adhesive elastic bandages and sports protective bandages. However, these common bandages are mostly made of gauze or cotton cloth, lacking elasticity and adjustment, resulting in poor comfort.

[0003] To address this issue, prior art CN219423135 U discloses a medical bandage. One specific embodiment of this medical bandage includes: a bandage body 40 and an adhesive layer disposed on the surface of the bandage body; the bandage body includes: a non-woven fabric base 10 and multiple elastic reinforcing filaments 30 sewn into the non-woven fabric base and extending warp along the non-woven fabric base. Each elastic reinforcing filament is pierced above and below the non-woven fabric base to form a continuous loop 31 around the non-woven fabric base. These elastic reinforcing filaments also give the bandage a certain degree of elasticity, thus facilitating bandaging and fixation. In optional production scenarios, the elastic reinforcing filaments can be pre-stretched when sewn into the non-woven fabric base. The resulting non-woven fabric base, in its natural state (i.e., without external force), exhibits a contracted and wrinkled state in the warp direction. After sufficient warp stretching, the length of this bandage can reach several times its initial length, and this contracted and wrinkled state improves the breathability of the bandage, making it suitable for various medical care situations. However, on the one hand, although the existing technology makes the bandage elastic, its elasticity is achieved by forming a continuous coil around the non-woven fabric substrate after the elastic reinforcing filaments are punctured above and below the non-woven fabric substrate, which is a complex process. On the other hand, it only has a bandaging function, which is single and difficult to inhibit bacteria in the wound. That is, it does not have a bacteriostatic or bactericidal effect, and it is difficult to prevent infection. It is extremely inconvenient to use.

[0004] Although there are already antibacterial bandage products on the market, they mainly obtain their antibacterial function by impregnation or coating with antibacterial coatings, and have poor breathability, moisture absorption and softness.

[0005] This application addresses the aforementioned problems by providing an elastic bandage with antibacterial properties and dynamic adjustment. This bandage has excellent breathability, moisture absorption, and softness, making bandaging more comfortable and less likely to cause allergies or skin discomfort. Utility Model Content

[0006] This utility model addresses the technical problems of existing bandages by providing an elastic bandage with antibacterial properties and dynamic adjustment. This bandage offers excellent breathability, moisture absorption, and softness, resulting in more comfortable bandaging and solving the problems mentioned in the background art.

[0007] This utility model is achieved through the following technical solution: the medical elastic bandage includes an elastic body, which comprises a first non-woven fabric layer and a second non-woven fabric layer with a pleated structure, and an spandex filament layer is disposed between the two non-woven fabric layers, and the two layers are bonded together by an adhesive layer. The pleated structure consists of crests and troughs connecting the crests, and the crests and troughs extend alternately along the longitudinal direction of the substrate layer.

[0008] This utility model has the following structural features:

[0009] (1) A plurality of welding parts are provided at intervals around the outer edge of the elastic body, wherein the welding parts connect the outer edges of the first nonwoven fabric layer, the second nonwoven fabric layer and the spandex filament layer into one piece.

[0010] (2) Along the longitudinal length of the elastic body, a first welding part and a second welding part are respectively provided in the central area of ​​the elastic body, an elastic-free area is provided between the two welding parts, a wrapping part is connected above the elastic-free area by an adhesive layer, and an antibacterial coating is provided on the wrapping part.

[0011] In a preferred embodiment, the bandaging portion is selected from viscose fiber cloth.

[0012] In a preferred embodiment, the bandaging part comprises two layers of viscose fiber cloth, with antibacterial popping beads disposed between the two layers of viscose fiber cloth.

[0013] In a preferred embodiment, the antibacterial coating is a SiO2-ZnO nanoparticle coating.

[0014] In a preferred embodiment, the welded portion is a parallelogram shape and is arranged around the outer edge of the elastic body at intervals of 2-10mm.

[0015] In a preferred embodiment, a roll of medical elastic bandage is formed by connecting several of the aforementioned medical elastic bandages along the longitudinal length direction. An easy-tear component is pre-set in the connecting portion, and the medical elastic bandage is obtained from the roll of medical elastic bandage through the easy-tear component.

[0016] In a preferred embodiment, the easy-tear component includes a plurality of tear openings spaced apart, the tear openings penetrating and communicating with the elastic body along the thickness direction of the elastic body, and spaced apart along the width direction of the elastic body.

[0017] In a preferred embodiment, the easy-tear component further includes V-shaped easy-tear notches on both sides of the connecting portion.

[0018] The beneficial technical effects of this utility model are as follows:

[0019] 1. The elastic body of this utility model has excellent softness, breathability, and elasticity adjustment performance, making wrapping more comfortable. At the same time, a welded part is set around the outer edge of the elastic body, thereby avoiding the problems of easy delamination between the non-woven fabric and spandex, flashing at the side opening, and exposure of spandex, ensuring good elasticity adjustment performance and maintaining aesthetics.

[0020] 2. This utility model sets an elastic-free zone in the central area of ​​the elastic body, which avoids the wrinkled state of the bandage in its natural state and is convenient to use.

[0021] 3. This utility model is equipped with an antibacterial coating and / or antibacterial burst beads, which have an antibacterial effect. When needed, the burst beads can be squeezed by hand to release the liquid inside. The bacteria are purified by the liquid inside the burst beads, and the two work together to inhibit bacteria, resulting in better antibacterial efficacy. Attached Figure Description

[0030] Unless otherwise expressly defined, the terms "fixed connection" or "fixed connection" used in the claims, description and drawings of this invention should be interpreted broadly to refer to any connection in which there is no displacement or relative rotation relationship between the two parties, including non-removable fixed connection, detachable fixed connection, integral connection and fixed connection by other means or components.

[0031] In the claims, description and accompanying drawings of this invention, the terms "comprising," "having," and variations thereof are used to mean "including but not limited to."

[0032] Please also refer to the appendix. Figure 2-5 The medical elastic bandage described in this application, such as elastic bandage 1 and elastic bandage 7, both include an elastic body 2. The structure of the elastic body 2 is consistent with that of the elastic waistbands widely used in disposable absorbent products, exhibiting excellent softness, breathability, and elastic adjustment performance. The elastic body 2 includes a first nonwoven fabric layer 21 and a second nonwoven fabric layer 23 with a pleated structure, and an spandex filament layer 22 is disposed between the two nonwoven fabric layers, which are then bonded together by an adhesive layer (not shown in the figure). The pleated structure consists of crests and troughs connecting the crests, with the crests and troughs extending alternately along the longitudinal direction of the substrate layer. This is prior art and is well-known to those skilled in the art.

[0033] This utility model has the following structural features:

[0034] Firstly, in order to achieve excellent softness, comfort, and elastic adjustment in the existing pleated elastic body 2, the amount of adhesive applied to its adhesive layer is relatively small. However, after the elastic body 2 is cut, its outer edges are all open, making it extremely easy for the non-woven fabric and spandex fibers to detach, causing the side openings to burst and exposing the spandex fibers. This affects both the overall structure and elastic adjustment performance of the elastic body, as well as its aesthetics. To solve this problem, this utility model achieves the following:

[0035] A plurality of welding portions 4 are spaced apart around the outer edge of the elastic body. The welding portions 4 (hot melt welding portions) circumferentially connect the outer edges of the first nonwoven fabric layer 21, the second nonwoven fabric layer 23, and the spandex filament layer 22 into a single unit. Specifically, the welding portions (hot melt welding portions) are preferably parallelogram-shaped and are arranged around the outer edge of the elastic body at intervals of 2-10 mm.

[0036] Through the above-described embodiments, the problems of easy delamination between nonwoven fabric and spandex yarn, side opening flashing, and exposure of spandex yarn are avoided, ensuring good elasticity adjustment performance and maintaining aesthetics. It also makes the elastic body of this utility model have excellent softness, breathability, and elasticity adjustment performance, making the bandaging more comfortable.

[0037] Secondly, the elastic body 2 has elastic adjustment properties in the longitudinal length direction, and its natural state has a pleated structure, which makes it difficult to set functional components on the elastic body 2. Therefore, this application achieves this by setting an elastic-free area 3. Specifically, the elastic-free area 3 is implemented in the following way:

[0038] Specifically, along the longitudinal length of the elastic body, a first welding portion 8 and a second welding portion 9 are respectively provided in the central region of the elastic body, both of which are hot-melt welds. Then, the spandex filament located between the first welding portion 8 and the second welding portion 9 is cut to make it lose its elasticity, thereby providing an elastic-free zone 3 between the two welding portions. In a specific embodiment, each spandex filament located between the first welding portion 8 and the second welding portion 9 is cut at intervals of 2-3 mm.

[0039] The above-described implementation of the elastic-free zone avoids wrinkles in the bandage in its natural state and is convenient to use.

[0040] Third, a bandaging portion 32 is connected to the non-elastic area 3 via an adhesive layer 33. An antibacterial coating 31 may be further provided on the bandaging portion 32. Alternatively, the antibacterial coating may not be provided on the bandaging portion 32.

[0041] Specifically, the antibacterial coating is a SiO2-ZnO nanoparticle coating. This SiO2-ZnO nanoparticle coating is selected from existing technologies, such as the prior art disclosed in publication number CN 116115815 A, "An antibacterial medical bandage and its preparation method," which involves "coating a SiO2-ZnO nanoparticle dispersion onto a non-woven fabric, placing the non-woven fabric in an oven to dry until the coating on the non-woven fabric is completely cured." The application of the antibacterial coating is existing technology and is already well-known and mastered by those skilled in the art.

[0042] Specifically, the wrapping portion 32 is selected from existing viscose fiber fabric. This viscose fiber has good moisture absorption.

[0043] In a preferred embodiment, the bandaging part 32 may be made of two layers of viscose fiber cloth 321, with an antibacterial bursting bead 322 disposed between the two layers of viscose fiber cloth. As the name suggests, the bursting bead described in this application needs to be able to be squeezed to burst and only then can it play a role. That is, after squeezing the bursting bead, the essential oil inside the bursting bead flows out and slowly evaporates to play a role.

[0044] The antibacterial burst beads described in this application have a core-shell structure, with antibacterial essential oil embedded in the shell layer. These antibacterial burst beads containing antibacterial essential oil components are widely used in existing products and can be obtained by those skilled in the art from commercially available goods or from existing technologies, such as the "Antibacterial Bursting Beads of Peony Root Bark Extract" disclosed in publication number CN115177558B, or the "Bursting Bead Essential Oil Drug" disclosed in publication number CN116392325A, and the "Highly Effective Antibacterial Bursting Bead Essential Oil" disclosed in publication number CN118383945A, etc.

[0045] Through the above-described embodiments, this invention has an antibacterial effect. When needed, the popping bead can be broken by hand, and the liquid inside the popping bead will flow out. The bacteria are purified by the liquid inside the popping bead, and the two work together to inhibit bacteria, resulting in a better antibacterial effect.

[0046] Most existing bandages are roll-shaped products, requiring scissors for cutting during use. Therefore, this application, based on the above-described embodiments, further provides an embodiment of a roll-shaped medical elastic bandage:

[0047] Firstly, a connecting part is provided between two adjacent elastic bandages 1 and elastic bandages 7 in the longitudinal length direction, that is: a roll of medical elastic bandages is formed by connecting parts along the longitudinal length direction.

[0048] Secondly, an easy-tear component is pre-installed at the connecting part, through which the medical elastic bandage is obtained from the rolled medical elastic bandage.

[0049] In a preferred embodiment, the easy-tear component includes: (1) a plurality of tear openings 5 ​​spaced apart, the tear openings 5 ​​penetrating and communicating with the elastic body 2 along the thickness direction of the elastic body, and spaced apart along the width direction of the elastic body; (2) V-shaped easy-tear notches 6 provided on both sides of the connecting portion, the V-shaped easy-tear notches 6 and the tear openings 5 ​​being located on the same axis.

[0050] In addition, for ease of use, a magic hook can be provided on one end of each elastic bandage near the connecting part. The bandage can be tied by hooking and connecting with the surface fiber mesh of the non-woven fabric layer. Alternatively, a fiber mesh corresponding to the magic hook can be additionally provided on the non-woven fabric layer to make the hook connection more secure. These conventional implementation methods are well known to those skilled in the art.

[0051] The foregoing description illustrates and describes preferred embodiments of the present invention. As previously stated, it should be understood that the present invention is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the inventive concept described herein through the foregoing teachings or related technical or knowledge. Any modifications and variations made by those skilled in the art that do not depart from the spirit and scope of the present invention should be within the protection scope of the appended claims.
