PASTING STRUCTURE

Abstract

The present invention is related to an pasting structure that comprises a back-material layer which is formed by attaching the film layer and the porous supporting layer to each other; and a gel layer, one side of the gel layer is bonded to the porous supporting layer and part of the gel layer penetrate pores; wherein the back-material layer and the gel layer closely adhered to each other to form a transparent pasting structure. The pasting structure of the present invention is used as wound dressing which easily observes the wound change and healing status at any time. In the meantime, that provides higher moisture permeability and comfort.

Claims

1. A pasting structure comprising: a back-material layer which is formed by attaching a film layer and a porous supporting layer to each other; and a gel layer which is boned to the porous supporting layer and part of the gel layer penetrates pores of the porous supporting layer, wherein the back-material layer and the gel layer are closely adhered to each other to form a pasting structure with a transmittance greater than 30%.

2. The pasting structure of claim 1, wherein the back-material layer and the gel layer are closely adhered to each other to form the pasting structure with a transmittance greater than 50%.

3. The pasting structure of claim 1, wherein the gel layer is formed by hydrogel being solidified.

4. The pasting structure of claim 1, wherein the gel layer comprises active ingredients.

5. The pasting structure of claim 1, wherein the gel layer comprises special dyes which react to different pH levels.

6. The pasting structure of claim 1, wherein the thickness of the film layer is 0.01-0.2 mm.

7. The pasting structure of claim 1, wherein the supporting layer is imprinted.

8. The pasting structure of claim 1, further comprising a release layer which is attached to another side of the gel layer.

9. The pasting structure of claim 8, wherein the release layer is paper or the film layer.

10. The pasting structure of claim 1, wherein the porous supporting layer is sprayed on the film layer so as to be designed with patterns or texts and the porous supporting layer is fixed on the film layer.

BRIEF DESCRIPTION OF THE DRAWINGS

[0025] FIG. 1 is schematic diagram of the pasting structure of the present invention.

[0026] FIG. 2 is schematic diagram of the porous material sprayed on the film layer to produce words of EB.

EXAMPLES

[0027] The preferred embodiment of the present invention will be described below for details, wherein the drawing numbers of the listed embodiments are same as the numbers shown in the drawings, please refer to the drawings and detailed description at the same time. The examples below are not limiting and merely are representative of some aspects and features of the present invention.

[0028] FIG. 1 is schematic diagram of pasting structure of present invention, the pasting structure 10 of the present invention comprises: a back-material layer 20, which is formed by attaching the film layer 21 and the porous supporting layer 22 to each other; and a gel layer 30, one side of that combined with the porous supporting layer 22 and the part of the gel layer 30 penetrates pores, wherein the back-material layer 20 and the gel layer 30 are closely adhere together to form a transparent pasting structure.

[0029] In a preferred embodiment, the porous supporting layer 22, which is polypropylene non-woven fabric, that is attached the film layer 21 composed of polyurethane film with pressure sensitive adhesives become the back-material layer 20. The thickness of the polyurethane film is 0.010.2 mm. The hydrogel is coated or soaked in the polypropylene non-woven fabric part of the back-material, the hydrogel fully penetrates into the polypropylene non-woven fabric and extend to a thickness and the thickness greater than non-woven fabric layer.

[0030] The hydrogel is solidified to form the gel layer 30 after UV irradiation or temperature change. The solidified gel penetrates into pores structure of the non-woven fabric, both of them combined together. The gel layer 30 and the back-material layer 20 adhered closely as an adhesive layer and appear transparent. When it used as wound dressings, it will be easily observed the change and healing status of the wound. In addition, the polyurethane film is a kind of moisture permeable film, which can be applied as wound dressings on the wound and provide higher moisture permeability and comfort.

[0031] In a preferred embodiment, according to the porous supporting layer 22 of the pasting structure 10 of the present invention, there is imprinting on it which embossed a specific type or symbol for identifying the source of the product, or the porous supporting layer is sprayed on the film layer so as to be designed with patterns or texts and the porous supporting layer is fixed on the film layer to identify the source of product or o enhance user's willing by the texts and patterns design.

[0032] In a preferred embodiment, according to the pasting structure 10 of the present invention, the gel layer 30 may comprise a special dye which reacts to different pH levels. When the pasting structures are used to treat wounds, and it will display in light green (green light) if the skin is weak acidic. When the wound skin is alkaline, the red warning will appear and remind the wounded and nursing people to clean and replace the wound dressings in time, and that saves previously need for additional time of getting and testing samples, it can improve the medical effect.

[0033] In a more preferred embodiment, according to the pasting structure 10 of the present invention, the porous supporting layer 22 may be coated with special dyes which react to different pH levels and designed texts or patterns. That generates the source of the product to identify or enhances user's wiliness and remind the wounded and nursing people to clean and replace the wound dressings in time, and that saves previously need for additional time of getting and testing samples, it improves the medical effect.

[0034] According to the pasting structure 10 of present invention, it further comprises a release layer 40, which attached to the other side of the gel layer. In the present embodiment, the release layer 40 is composed of polyurethane (PU) and the gel layer is made of hydrogel.

[0035] Although the present invention is implemented as described above, it not limited to present invention. The person in the art can make changes and modifications within the spirit and the range in the present invention. Therefore, the protection scope of the present invention takes claims of the present specification as the reference.
