DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-3 , this embodiment provides a technical solution: an efficient healing dressing, including an adhesive pad 5;
[0021] Adhesive pad 5: It includes a non-woven fabric 51 and an adhesive layer 52. The outer edge of the upper surface of the non-woven fabric 51 is provided with an adhesive layer 52, which is used to adhere the non-woven fabric 51 to the skin surface by the adhesive layer 52, acting as a temporary barrier instead of the damaged skin. In the middle of the upper surface of the non-woven fabric 51, there is a first absorption layer 6. In the middle of the upper surface of the first absorption layer 6, there is a waterproof film 3. On the upper surface of the waterproof film 3, there is an efficient healing agent 2, which accelerates the healing of the wound surface. The waterproof film 3 is used to block the infiltration of external water vapor into the efficient healing agent 2, reducing the loss of the efficacy of the efficient healing agent 2. On the outer edge of the upper surface of the first absorption layer 6, there is a second absorption layer 4. On the upper surface of the overall combination of the second absorption layer 4 and the efficient healing agent 2, there is a composite fiber layer 1. The fiber factors of the composite fiber layer 1 are used as healing agents, and through cooperation with the efficient healing agent 2, the healing of the wound is accelerated. The outer edge of the composite fiber layer 1 is adhered to the non-woven fabric 51 by the adhesive layer 52, fixing the composite fiber layer 1 and the material layers inside it on the surface of the non-woven fabric 51. The adhesive pad 5 further includes a side release film 53 and a main release film 54. The side release film 53 is adhered to the front and rear ends of the upper surface of the non-woven fabric 51 by the adhesive layer 52 respectively. The main release film 54 is adhered to the upper surface of the non-woven fabric 51 by the adhesive layer 52, and the main release film 54 is located above the side release film 53. First, tear off the main release film 54, and adhere the left and right ends of the non-woven fabric 51 to the human skin through the adhesive layer 52. During the adhesion process, the adhesive layer 52 in the middle of the non-woven fabric 51 is blocked by the side release film 53 and does not come into contact with the skin, facilitating the control of the pasting position of the dressing. Then, tear off the side release film 53, making the front and rear ends of the non-woven fabric 51 adhere to the human skin. The adhesive pad 5 further includes a tear strip 55, and the tear strip 55 is respectively arranged at the right ends of the side release film 53 and the main release film 54, facilitating the tearing of the side release film 53 and the main release film 54. The side release film 53, the main release film 54, and the tear strip 55 are all polyethylene release films, having high strength and high transparency. The first absorption layer 6 is an alginate layer, and the second absorption layer 4 is a cotton paper layer. The second absorption layer 4 is used to absorb the exudate of the wound surface. When there is more exudate, the first absorption layer 6 quickly absorbs a large amount of exudate, preventing the skin from being in a humid environment and breeding bacteria, resulting in wound surface infection. The surface of the non-woven fabric 51 is evenly provided with ventilation holes, and the ventilation holes provided on the surface of the non-woven fabric 51 ensure sufficient air permeability of the dressing and accelerate the recovery speed.
[0022] The working principle of an efficient healing dressing provided by the present utility model is as follows: When in use, first tear off the main release film 54, and adhere the left and right ends of the non-woven fabric 51 to the human skin through the adhesive layer 52. During the adhesion process, the adhesive layer 52 in the middle of the non-woven fabric 51 is blocked by the side release film 53 and does not come into contact with the skin, which is convenient for controlling the pasting position of the dressing. Then tear off the side release film 53 to make the front and back ends of the non-woven fabric 51 adhere to the human skin. During the use process, the fiber factors of the composite fiber layer 1 are used as healing agents, and in cooperation with the efficient healing agent 2, the healing of the wound is accelerated. The waterproof film 3 is used to block the penetration of external water vapor into the efficient healing agent 2 and reduce the loss of the efficacy of the efficient healing agent 2; the second absorption layer 4 is used to absorb the exudate on the wound surface. When the exudate is relatively large, the first absorption layer 6 is used to quickly absorb a large amount of exudate to prevent the skin from being in a humid environment and breeding bacteria, resulting in wound infection. At the same time, the breathable holes provided on the surface of the non-woven fabric 51 are used to ensure sufficient breathability of the dressing and accelerate the recovery speed.
[0023] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be similarly included in the patent protection scope of the present utility model.
