They are insufficient in terms of drug support to promote wound healing, resulting in limited effectiveness in wound healing and poor treatment results and patient recovery experience.

[0004] Therefore, there is an urgent need to provide a skin wound protection patch with drug release function to promote wound healing. Utility Model Content

[0005] To overcome the shortcomings of existing wound protection products, such as limited functionality and lack of drug support to promote wound healing, resulting in limited wound healing effects and poor treatment outcomes and patient recovery experience, this utility model provides a skin wound protection patch with drug release function to promote wound healing.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: a skin wound protective dressing, comprising a dressing body, wherein the dressing body is composed of a breathable layer, a stabilizing band, an antibacterial layer, a drug-releasing layer, and a contact layer arranged sequentially from top to bottom; wherein, the breathable layer is located on the outermost surface; the stabilizing band is disposed on both sides of the breathable layer, and the side of the stabilizing band in contact with the skin is coated with an adhesive; the antibacterial layer is immediately below the stabilizing band; the drug-releasing layer is located below the antibacterial layer; and the contact layer is located at the bottom layer, directly contacting the skin.

[0007] In a preferred embodiment of the present invention, a color-changing material layer is provided between the antibacterial layer and the drug release layer.

[0008] In a preferred embodiment of this utility model, the surface of the breathable layer and the stabilizing belt is provided with a waterproof sticker.

[0009] In a preferred embodiment of this utility model, the waterproof sticker has small ventilation holes in the middle.

[0010] In a preferred embodiment of this utility model, the protective sticker body is wrapped and sealed in a special packaging bag.

[0011] In a preferred embodiment of this utility model, the packaging bag has a serrated cut on its side.

[0012] Compared with the prior art, the present invention has the following technical effects: 1. The product provides an effective physical barrier for the wound through a multi-layer basic structure such as a breathable layer, an antibacterial layer and a contact layer, preventing external bacteria and other pollutants from entering the wound, thereby reducing the risk of infection. Furthermore, the built-in drug release layer continuously releases antibiotics, analgesics or growth factors, which helps to relieve pain and control local inflammatory response, thereby promoting faster wound healing.

[0013] 2. By adding a color-changing material layer between the antibacterial layer and the drug release layer, the color change can visually reflect the pH change of the wound environment when the wound becomes infected, thus providing important information about the wound condition. This helps medical staff or patients to understand the wound condition in a timely manner and take measures to prevent the condition from worsening. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-4 A skin wound protective dressing includes a dressing body 1, which is composed of a breathable layer 101, a stabilizing band 102, an antibacterial layer 104, a drug-releasing layer 105, and a contact layer 106 arranged sequentially from top to bottom. The breathable layer 101, located on the outermost surface, is made of non-woven fabric to help maintain appropriate moisture and airflow at the wound site. The stabilizing band 102 is located on the left and right sides of the breathable layer 101, and the side of the stabilizing band 102 that contacts the skin is coated with an adhesive 103 for protection. The patch adheres firmly; the antibacterial layer 104 is located immediately below the stabilizing band 102 and contains silver ions, iodine, or other antibacterial components, which can effectively inhibit bacterial growth and reduce the risk of infection; the drug release layer 105 is located below the antibacterial layer 104 and can accelerate the wound healing process by releasing components such as antibiotics, analgesics, or growth factors; the contact layer 106 is at the bottom layer and comes into direct contact with the skin. It is made of non-sticky, soft material, which increases the comfort of wearing the patch and reduces damage to newly formed tissue when changing the patch.

[0022] When using the skin wound protection patch, locate the serrated cut 41 on one side of the packaging bag 4, carefully tear open the packaging along the cut, align the contact layer 106 of the patch with the wound, place it down smoothly and gently press the surrounding stabilizing bands 102 to ensure it adheres firmly to the skin. Through the multi-layer structure of the breathable layer 101, antibacterial layer 104 and contact layer 106, it provides an effective physical barrier for the wound, preventing external bacteria and other contaminants from entering the wound, thereby reducing the risk of infection. Among them, the silver ions, iodine or other antibacterial ingredients contained in the antibacterial layer 104 can effectively inhibit bacterial growth, further reducing the possibility of infection and creating an environment conducive to wound healing. The drug release layer 105 can continuously release antibiotics, analgesics or growth factors, which help relieve pain, control local inflammatory response, and promote faster wound healing.

[0023] Example 2: Based on Example 1, please refer to... Figure 4A color-changing material layer 2 is provided between the antibacterial layer 104 and the drug release layer 105. The color-changing material layer 2 is made of dye that can detect changes in the pH level of the human body. These materials will change color when they come into contact with specific substances, thereby providing a method for intuitively monitoring the pH fluctuation of the wound environment.

[0024] When a wound becomes infected, the local bacterial metabolites cause the pH value to rise, and the wound site changes from weakly acidic to alkaline, indicating that complications have occurred at the wound site. The color-changing material layer 2 can sensitively respond to this change and indicate the potential risk of infection through color changes, such as changing from yellow to purple, so that medical staff can take measures to intervene and prevent the condition from worsening.

[0025] Please see Figure 2 The surface of the breathable layer 101 and the stabilizing band 102 is provided with a waterproof patch 3 to enhance the overall waterproof performance of the protective patch and prevent moisture from penetrating into the wound area from the outside. The waterproof patch 3 has a small ventilation mesh 31 in the middle position. The ventilation mesh 31 is designed fine enough to block liquid from passing through while ensuring air circulation, thereby maintaining appropriate humidity and oxygen exchange at the wound site, which helps to promote the wound healing process.

[0026] Please see Figure 5 The protective patch body 1 is wrapped and sealed in a special packaging bag 4 to ensure the sterility of the protective patch before use; the packaging bag 4 has a serrated cut 41 on the side, which makes it convenient for users to open the packaging bag 4 quickly and easily.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
