Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical devices, in particular to a corner structure of a self-adhesive auxiliary material. Background Art
[0002] Self-adhesive dressings are medical dressings with self-adhesive properties. They are typically made from medical-grade non-woven fabrics or other materials, coated with a self-adhesive medical adhesive, and can be applied directly to wounds without the need for additional fixings. As a convenient, comfortable, and effective medical product, self-adhesive sterile dressings are increasingly used in postoperative wound care, acute wound management, and surface wound repair.
[0003] At present, the corners of traditional self-adhesive accessories are generally of two types: right-angle design and rounded corner design. The right-angle design has low production technology requirements, but the right angle is more likely to rub against the fabric accessories when the product is actually used, resulting in curling at the right angle and forming point-like debonding, which in turn leads to partial or complete failure of the product. The rounded corner design has release paper tear notches on both sides. For products with larger release paper on both sides than the accessories, the rounded corners will increase production costs during production, and the rounded corner lines and protruding release material of the product will affect the overall appearance. A corner structure of a self-adhesive accessory is now proposed to solve the above problems. Utility Model Content
[0004] In order to solve the problems raised in the above background technology, the utility model provides a corner structure of a self-adhesive auxiliary material.
[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a corner structure of a self-adhesive auxiliary material, comprising: a medical auxiliary material layer, wherein both ends of the medical auxiliary material layer are provided with peeling notches of an isosceles trapezoidal structure, wherein the peeling notch includes a second side edge, and the two ends of the medical auxiliary material layer are provided with a first corner and a second corner, wherein the first side edge is tangent to the first corner, and the second side edge is tangent to the medical auxiliary material; medical glue, wherein the medical glue is provided on one side of the medical auxiliary material layer; and a release material layer, wherein the release material layer is bonded to the medical auxiliary material layer by the medical glue.
[0006] Preferably, the material of the medical auxiliary material layer is one of medical PU film and polyurethane material.
[0007] Preferably, the medical auxiliary material layer is located in the middle of the release material layer and the area of the medical auxiliary material layer is smaller than that of the release material layer.
[0008] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0009] The utility model provides peeling tear notches larger than the medical auxiliary material itself on both sides of the medical auxiliary material layer, and avoids right-angle design through the first corner and the second corner, which can effectively prevent the right angle from rubbing against the fabric auxiliary material and is not easy to produce curling; the production process requirements are low, the product yield is high, and the production cost is reduced; the lines are simple and the product is beautiful.

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0014] like Figures 1 to 2 As shown, the utility model provides a corner structure of a self-adhesive auxiliary material, comprising: a medical auxiliary material layer 1, wherein both ends of the medical auxiliary material layer 1 are provided with peeling notches of an isosceles trapezoidal structure, wherein the peeling notch includes a second side edge 104, and the 1 includes two first side edges 103, and both ends of the medical auxiliary material layer 1 are provided with a first corner 101 and a second corner 102, wherein the first side edge is tangent to the first corner 101, and the second side edge 104 is tangent to 102; medical glue, wherein the medical glue is provided on one side of the medical auxiliary material layer; and a release material layer, wherein the release material layer is bonded to the medical auxiliary material layer by the medical glue.
[0015] By providing peeling notches larger than the medical auxiliary material itself on both sides of the medical auxiliary material layer 1 and avoiding a right-angle design through the first corner 101 and the second corner 102, it is possible to effectively prevent the right angle from rubbing against the fabric auxiliary material, and curling is less likely to occur; the production process requirements are low, the product yield is high, and the production cost is reduced; the lines are simple and the product is beautiful.
[0016] like Figure 1 As shown, the material of the medical auxiliary material layer 1 is one of medical PU film and polyurethane material. The medical auxiliary material layer 1 is located in the middle of the release material layer 3 and the area of the medical auxiliary material layer 1 is smaller than that of the release material layer 3.
