Description

Technical Field

[0001] This utility model relates to the field of medical consumables, and in particular to a bandage suitable for joints. Background Technology

[0002] Bandages are commonly used surgical supplies to immobilize and protect surgical or injured areas. However, conventional bandages lack sufficient elasticity when dealing with open wounds at the elbows and knees, easily becoming overly tight and wrinkled when the joint is bent, and failing to return to their original shape after straightening, which is detrimental to the healing of open wounds. Chinese utility model patent CN206138275U discloses a self-adhesive elastic bandage with good elasticity, but it only provides immobilization and has room for further improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a bandage that is more elastic and fits the skin better to accommodate open wounds on elbows, knees and other joints that are subject to large movements.

[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows: a bandage suitable for joints, comprising a skin-friendly cotton layer, a mesh layer, and a self-adhesive elastic bandage layer arranged sequentially, wherein the skin-friendly cotton layer is in the form of blocks and is distributed in the mesh layer with certain gaps between them; the self-adhesive elastic bandage layer also extends out with a fixing strap.

[0005] To improve the fit between the bandage and the joint, and to give the bandage a better stretching and contraction effect during joint movement, the technical solution provided by this utility model includes: the mesh layer is woven from elastic fibers.

[0006] To further improve the fit between the bandage and the wound, the technical solution provided by this utility model includes a base adhesive layer provided on the upper part of the mesh layer in the gap between the skin-friendly surface layers.

[0007] To promote wound healing, the technical solution provided by this utility model includes: at least a portion of the skin-friendly surface layer contains a medicated pad layer.

[0008] To achieve effective wound protection, a skin-friendly cotton layer containing a medicated pad is fixed to the wound. The embodiment provided by this utility model includes a base adhesive layer arranged in a single direction, and a skin-friendly surface layer containing a medicated pad disposed between the base adhesive layers.

[0009] Furthermore, the base layer set on the mesh layer in the gaps between the skin-friendly surface layers is arranged in a dotted pattern.

[0010] To facilitate continuous production, the fixing straps are located at both ends of the self-adhesive elastic bandage layer and are achieved through pre-cutting, with one end being "convex" and the other end being "concave".

[0011] The advantages and beneficial effects of this utility model are as follows: the skin-friendly surface layer, the mesh layer, and the self-adhesive elastic bandage layer arranged sequentially are all breathable structures, which are not conducive to the growth and reproduction of anaerobic bacteria. The skin-friendly surface layer and the self-adhesive elastic bandage layer are combined together by using a mesh layer woven from elastic fibers. The skin-friendly surface layer contains a medicated pad layer, which is conducive to wound healing. The mesh layer can make the skin-friendly cotton layer, which has poor elasticity, have a certain stretching effect in all directions. The skin-friendly surface layer is block-shaped with certain gaps between each other, so that the skin-friendly surface layer has a certain compression space, which can better accommodate the large range of motion of the elbow and knee joints. A base adhesive layer is intermittently arranged outside the skin-friendly cotton layer containing the medicated pad layer. The base adhesive layer can adhere to the skin, thereby fixing the skin-friendly cotton layer containing the medicated pad layer relative to the wound position. By extending the self-adhesive elastic bandage layer with two fixing straps of "concave" and "convex", the tightness of the bandage can be adjusted within a small range, and it is suitable for production line processing.

Detailed Implementation

[0013] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0014] Example 1 like Figures 1-2A bandage suitable for joints includes a skin-friendly cotton layer 1, a mesh layer 2, and a self-adhesive elastic bandage layer 3 arranged sequentially. The mesh layer 2 is woven from elastic fibers. The skin-friendly cotton layer 1 is block-shaped and distributed in the mesh layer 2 with certain gaps between each other. The self-adhesive elastic bandage layer 3 also extends a fixing strap 4, which is located at both ends of the self-adhesive elastic bandage layer 3, one end being "convex" and the other end being "concave". A base adhesive layer 5 is provided on the mesh layer in the gaps between the skin-friendly surface layers. The base adhesive layer 5 is strip-shaped and distributed in the same direction as the mesh layer 2, and the skin-friendly surface layer 1 containing the medicated pad layer is placed between the base adhesive layers 5.

[0015] In this embodiment, the skin-friendly surface layer 1, the mesh layer 2, and the self-adhesive elastic bandage layer 3, arranged sequentially, are all breathable structures, which are not conducive to the growth and reproduction of anaerobic bacteria. The skin-friendly surface layer and the self-adhesive elastic bandage layer 3 are combined together by using the mesh layer 2 woven from elastic fibers. The skin-friendly surface layer 1 contains a medicated pad layer 6, which is beneficial to wound healing. The mesh layer 2 allows the skin-friendly cotton layer 1, which has poor elasticity, to have a certain degree of stretching effect in all directions. The skin-friendly surface layer 1 is block-shaped with certain gaps between each other, so that the skin-friendly surface layer 1 has a certain compression space, which can better accommodate the large range of motion of the elbow and knee joints. Intermittently arranged outside the skin-friendly cotton layer 1 containing the medicated pad layer 6 are... The base layer 5 adheres to the skin, thus fixing the medicated padding layer 1 relative to the wound position. This facilitates the absorption of the medicated padding layer 6 by the wound and reduces deformation caused by stress during joint movement. The base layer 5 is distributed along the same direction as the mesh layer 2. During use, because the base layer has low elasticity, it significantly affects the elasticity of the bandage. Therefore, the strip-shaped base layer 5 should be perpendicular to or at a certain angle to the plane formed by joint movement to minimize the reduction in bandage elasticity caused by the base layer 5. The base layer 5 extends from the self-adhesive elastic bandage layer, forming two concave and convex fixing bands 4, such as... Figure 4 Relying on the self-adhesive elastic bandage layer 3, such as Figure 4 Overlapping the concave and convex securing straps can prevent the bandage from curling at the edges; for example... Figure 2 The fixing strap is achieved through pre-cut marks 7, which facilitates quick tearing and segmentation of the bandage after it is rolled up, making it suitable for wounds of different sizes and also suitable for production line processing.

[0016] Example 2 like Figure 3A bandage suitable for joints includes a skin-friendly cotton layer 1, a mesh layer 2, and a self-adhesive elastic bandage layer 3 arranged sequentially. The mesh layer 2 is woven from elastic fibers. The skin-friendly cotton layer 1 is block-shaped and distributed in the mesh layer 2 with certain gaps between each other. The self-adhesive elastic bandage layer 3 also extends a fixing band 4, which is located at both ends of the self-adhesive elastic bandage layer 3, one end being "convex" and the other end being "concave". A base adhesive layer 5 is provided on the mesh layer in the gaps between the skin-friendly surface layers. The base adhesive layer 5 is dot-shaped and distributed in the same direction as the mesh layer 2, and the skin-friendly surface layer 1 containing the medicated pad layer is placed between the base adhesive layers 5.

[0017] The function of the base layer 5 is to stabilize the bandage at the wound site. Unlike Example 1, the base layer 5 of Example 2 is dotted. Although the stabilizing effect is worse than that of Example 1, it has the least impact on the elasticity of the bandage.

[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
