Description

Technical Field

[0001] This utility model belongs to the field of medical dressing technology, specifically, it relates to a dressing structure that fits flat. Background Technology

[0002] Dressings are widely used in daily life. A dressing typically consists of an adhesive layer, an outer backing layer, and a core layer. The core layer is applied to the wound surface to prevent further infection. However, with existing dressings, the outer backing layer, because it occupies the outer surface area, tends to wrinkle when applied to the skin due to unevenness. Furthermore, to protect the wound, repeated application is not recommended. These wrinkles can cause discomfort and a foreign body sensation for the patient, and also affect the seal, leading to edge lifting and further infection.

[0003] Therefore, there is an urgent need for a dressing structure that adheres smoothly, does not curl or wrinkle, and is suitable for direct operation by a single person. Utility Model Content

[0004] In view of this, the technical problem to be solved by this utility model is to provide a dressing structure that fits flat and avoids the problems of uneven application, easy wrinkling, and discomfort for patients caused by previous dressings.

[0005] To solve the above-mentioned technical problems, this utility model discloses a dressing structure that fits flat and conforms to the skin, comprising:

[0006] The backing layer and the core layer located in the center of the backing layer, wherein the backing layer is cross-shaped, having a support portion in the center and an edge portion around the perimeter, the support portion is provided with the core layer, and the edge portion is divided into three spaced sub-edges by providing cuts; the support portion is coated with a pressure-sensitive silicone mesh layer, and the pressure-sensitive silicone mesh layer is set as a square grid in the edge portion and as a honeycomb grid in the support portion.

[0007] According to one embodiment of the present invention, the end edge of the aforementioned sub-attachment is provided with an extended fixing wing. The extended fixing wing is formed by laser forming a micro-hole array with a micro-hole diameter of 0.2 mm and coated with acrylic adhesive with a width of 3-5 mm.

[0008] According to one embodiment of the present invention, the extended fixed wing is configured as a serrated shape.

[0009] According to one embodiment of the present invention, the end of the aforementioned edge portion is rounded.

[0010] According to one embodiment of the present invention, the backing layer is configured as a polyurethane film.

[0011] According to one embodiment of the present invention, the core layer includes a polyurethane foam absorbent layer bonded to the backing layer and a silicone wound contact layer attached to its surface.

[0012] Compared with the prior art, the present invention can achieve the following technical effects:

[0013] By setting a cross-shaped backing layer, divided into four wings, and further divided into three sub-edges, the dressing is designed to ensure that it does not wrinkle when applied to joints / moving areas, avoiding friction and discomfort. In addition, the pressure-sensitive silicone mesh layer is designed with a honeycomb grid to reinforce the support of the dressing layer, and square grids are set around the perimeter to improve tensile strength and skin adhesion, making it more comfortable to use.

[0014] The backing layer has serrated extended fixing wings along its edges, and the adhesive backing is coated with highly viscous acrylic glue, making it less prone to peeling and easy to tear off.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the above-mentioned technical effects at the same time. Attached Figure Description

[0019] Backing layer 10, core layer 20, support part 31, edge part 32, extension fixing wing 40. Detailed Implementation

[0020] The following will describe in detail the implementation of this utility model with reference to the accompanying drawings and embodiments, so that the implementation of this utility model can be fully understood and carried out based on how technical means are used to solve technical problems and achieve technical effects.

[0021] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the well-fitting dressing structure according to an embodiment of the present invention.

[0022] As shown in the figure, a flat and fitting dressing structure includes: a backing layer 10 and a core layer 20 located in the center of the backing layer 10. The backing layer 10 is cross-shaped, with a support portion 31 located in the center and an edge portion 32 around the perimeter. The support portion 31 is provided with the core layer 20, and the edge portion 32 is divided into three spaced sub-edges by providing cuts. The support portion 31 is coated with a pressure-sensitive silicone mesh layer, and the pressure-sensitive silicone mesh layer is set as a square grid in the edge portion 32 and as a honeycomb grid in the support portion 31.

[0023] In one embodiment of this utility model, the backing layer 10 and the core layer 20 form a whole dressing, with a release film adhered to its surface for protection, which can be removed before use. The backing layer 10 is cross-shaped, consisting of a central support portion 31 and surrounding edge portions 32. The edge portions 32 are wing-shaped, forming four edges for easy application. Each edge portion 32 is further cut into three independent sub-edges. This greatly increases operability during application, reduces the adhesive area, makes operation more flexible, and reduces wrinkling.

[0024] The backing layer 10 is coated with a medical-grade pressure-sensitive silicone mesh layer, which adheres to the skin and the dressing layer 20. Notably, the central support portion 31 of the pressure-sensitive silicone mesh layer features a honeycomb grid design, enhancing the dressing's support strength, cushioning pressure, and improving stability. The surrounding edge portion 32, however, is designed with a square grid, allowing for longitudinal expansion and contraction to accommodate joint movement and improve flexibility.

[0025] In addition, the end edge of the sub-adhesive is provided with an extended fixing wing 40, which is an extended edge. The extended fixing wing 40 is formed by laser forming a micro-pore array with a micro-pore diameter of 0.2mm and coated with acrylic adhesive. The acrylic adhesive has stronger adhesion and fits the skin surface with the micro-pores, making it less prone to lifting. The width is 3-5mm.

[0026] In a preferred embodiment, the extended fixed wing 40 is configured in a serrated shape, making it easier to tear off.

[0027] Furthermore, the edges of the 32-sided part are rounded at the ends, resulting in a high degree of comfort.

[0028] The backing layer 10 of this invention is a polyurethane film, which has a wide range of applications.

[0029] The dressing core layer 20 includes a polyurethane foam absorbent layer bonded to the backing layer 10 and a silicone wound contact layer attached to its surface, thus fulfilling the function of a hemostatic dressing.

[0030] In summary, this utility model, by setting a cross-shaped backing layer, is divided into four wings and further divided into three sub-edges, to ensure that the dressing does not wrinkle when applied to joints / moving areas, avoiding friction and discomfort. In addition, the pressure-sensitive silicone mesh layer is set with a honeycomb grid to reinforce the support of the dressing layer, and square grids are set around the perimeter to improve tensile strength and skin adhesion, making it more comfortable to use.

[0031] The foregoing description illustrates and describes several preferred embodiments of the present invention. However, 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 techniques or knowledge in related fields. 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.
