[0009] Furthermore, the indicator paper is blue.
[0010] Furthermore, the second release paper includes a third half and a fourth half, wherein a folded portion is formed at the end of the fourth half near the third half, and the folded portion is arranged between the third half and the fourth half.
[0011] Furthermore, an annular adhesive strip is provided on the side of the second release paper facing the PU film, and the annular adhesive strip is bonded to the PU film.
[0012] Furthermore, a note label is provided on the first surface, and the note label is arranged between the first release paper and the PU film.
[0013] In summary, compared with the prior art, this utility model has the following beneficial effects:
[0014] The dressing is used to cover and protect the wound; the PU film is transparent, breathable, and highly elastic, and can be attached to the wound to facilitate observation of the skin at the wound site; the first release paper is placed on the first surface to protect the first surface of the PU film and prevent dust and impurities from adhering to the first surface; the second release paper is placed on the second surface to protect the adhesive layer and the dressing and prevent dust and impurities from adhering to the adhesive layer and the dressing.

Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.
[0020] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "inner," and "outer," which indicate directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0022] To improve or solve the technical problem in existing technologies where dressings made of non-woven fabric make it difficult to observe the skin condition at the wound site, this utility model provides a breathable PU dressing. The breathable dressing includes: a PU film 1 having a first side and a second side facing each other, with an adhesive layer disposed on the second side; a first release paper 2, adhered to the first side by a non-adhesive; a dressing 3, adhered to the second side; and a second release paper 4, adhered to the second side and used in conjunction with the PU film 1 to cover the dressing 3.
[0023] Figure 1 This is a schematic diagram of an embodiment of the PU breathable dressing of this utility model. Figure 2 This is another schematic diagram of an embodiment of the PU breathable dressing of this utility model. (See diagram below.) Figure 1 and Figure 2 As shown, the present invention provides a PU breathable dressing comprising a PU film 1, a first release paper 2, a dressing 3, and a second release paper 4.
[0024] See also Figure 1 and Figure 2 PU film 1, or polyurethane film, is transparent, breathable, and highly elastic, allowing it to be applied to a wound for easy observation of the skin. In one or more embodiments, PU film 1 has a first side and a second side. A first release paper 2 is disposed on the first side, and a dressing 3 and a second release paper 4 are disposed on the second side. Specifically, an adhesive layer is provided on the second side for adhering the dressing 3 and the second release paper 4. A label 11 is provided on the first side, positioned between the PU film 1 and the first release paper 2. The label 11 is affixed to the first side and near the end of the PU film 1.
[0025] See also Figure 1 and Figure 2 The first release paper 2 is adhered to the first surface by non-adhesive. Specifically, the first release paper 2 includes a first half 21 and a second half 22 connected to the first half 21. The first half 21 and the second half 22 are connected by a wavy break, and the break of the first half 21 matches the break of the second half 22. Further, a positioning paper 23 is arranged at the break of the first half 21 and the second half 22. The positioning paper 23 has a different color from the first release paper 2. Specifically, the first release paper 2 is transparent, and the positioning paper 23 is blue, making it easy for the user to confirm the break position and tear off the first half 21 and the second half 22 to both sides. Further, a frosted layer is formed on the side of the positioning paper 23 that is opposite to the first release paper 2, which increases the friction of the positioning paper 23, making it easier for the user to pinch the positioning paper 23 and tear off the first release paper 2.
[0026] See also Figure 1 and Figure 2 The dressing 3 is positioned in the middle of the PU film 1 and is wrapped between the PU film 1 and the second release paper 4. In one or more embodiments, the second release paper 4 includes a third half 41 and a fourth half 42. Based on Figure 2 As shown, the third half 41 is positioned on the left and the fourth half 42 on the right. A folded portion 43 is formed at the end of the fourth half 42, folding away from the left end of the fourth half 42 towards the dressing 3. The third half 41 extends towards the fourth half 42 and covers the folded portion 43, meaning the folded portion 43 is located between the third half 41 and the fourth half 42. In use, the third half 41 is peeled off first, followed by the fourth half 42. Furthermore, an annular adhesive strip 44 is provided on the side of the second release paper 4 facing the PU film 1, forming an adhesive fit with the PU film 1. Specifically, the annular adhesive strip 44 is arranged circumferentially around the PU film 1. The adhesive force between the annular adhesive strip 44 and the PU film 1 is greater than the adhesive force between the second release paper 4 and the PU film 1, preventing the second release paper 4 from being accidentally torn.
[0027] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the protection scope of this utility model.
