[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Example 1, please refer to Figure 3 and Figure 4A head trauma dressing structure includes a dressing body 1, with an adhesive layer 101 disposed on the edge of one side of the dressing body 1 for adhering the dressing body 1 to the patient's scalp; a first fixing piece 2 is disposed on the circumferential side of the dressing body 1, and a first adhesive layer 201 is disposed on the first fixing piece 2 for adhering the first fixing piece 2 and the dressing body 1 to the patient's hair during use; From the perspective of fixation, the direct adhesion of the adhesive layer 101 of the dressing to the scalp can quickly position the dressing body 1 above the wound, reducing its random slippage and laying a stable foundation for subsequent fixation operations. The adhesion of the first adhesive layer 201 to the hair uses the hair as a natural fixation support, which increases the fixation effect. This dual fixation method greatly improves the stability of the dressing body 1 in the initial stage. Even if the patient has slight head movements in a short period of time, the dressing body 1 can maintain its relative position, providing strong protection for the initial protection of the wound. Furthermore, the first fixing piece 2 is used to fold towards the dressing body 1 after the adhesive layer 101 of the dressing is adhered to the patient's scalp to clamp the patient's hair. The first fixing piece 2 and the dressing body 1 are connected to the patient's hair by the adhesion of the first adhesive layer 201. That is, the dressing body 1 is fixed by the cooperation of the first fixing piece 2 and the patient's hair, which improves the stability of the dressing body 1 during use and reduces the occurrence of falling off.

[0022] The dressing body 1 includes an outer layer 102, a middle layer 103, and a contact layer 104. The middle layer 103 connects the outer layer 102 and the contact layer 104. The middle layer 103 is made of 3D honeycomb superabsorbent fiber, and the contact layer 104 is made of nano-silver-chitosan composite hydrogel. Nano-silver has antibacterial properties, which is very important in medical dressings to prevent infection. Chitosan itself also has antibacterial and biocompatibility and is often used for wound healing. The outer layer 102 is either a silver ion-containing antibacterial dressing or a regular gauze pad. The silver ions in the silver ion-containing antibacterial dressing can destroy the cell wall and cell membrane of bacteria and interfere with the metabolic process of bacteria, thereby achieving the purpose of antibacterial treatment. The regular gauze pad is mainly made of natural fibers, which has good water absorption and breathability and can meet the care needs of simple wounds.

[0023] The adhesive layer 101 of the dressing uses an ultra-thin medical silicone base, and the edges of the adhesive layer 101 adopt a biomimetic gecko foot structure, which is suitable for short hair and hairless individuals. Specifically, on the surface of the adhesive layer 101, densely arranged micron-sized columnar or sheet-like protrusions are formed through micro-nano processing technology, mimicking the geometry of the setae on a gecko's foot. The gecko foot achieves strong adhesion and reversible peeling characteristics through van der Waals forces (intermolecular forces), which can significantly increase the surface area in contact with the scalp, achieve high adhesion strength through van der Waals forces, and improve the overall adhesion stability.

[0024] Example 2 further optimizes the head trauma dressing structure provided in Example 1, specifically, as follows: Figures 3-4 As shown, a second fixing piece 3 is provided on the side of the first fixing piece 2, and a second adhesive layer 301 is provided on the second fixing piece 3. The second fixing piece 3 and the first fixing piece 2 work together to fix the hair in different positions by clamping and bonding the hair twice. This multi-dimensional fixing method constrains the dressing body 1 from multiple directions, greatly reducing the probability of the dressing falling off.

[0025] Furthermore, the second fixing piece 3 is used to fold towards the first fixing piece 2 after the adhesive layer 101 of the dressing is adhered to the patient's scalp to clamp the patient's hair. The second fixing piece 3 and the first fixing piece 2 are connected to the patient's hair under the adhesion of the second adhesive layer 301. That is, the dressing body 1 is fixed by the cooperation of the first fixing piece 2, the second fixing piece 3 and the patient's hair, which improves the stability of the dressing body 1 during use and reduces the occurrence of falling off.

[0026] Furthermore, such as Figure 3 As shown, a third fixing piece 4 is provided on the side of the second fixing piece 3, and a third adhesive layer 401 is provided on the third fixing piece 4.

[0027] Furthermore, the third fixing piece 4 is used to fold towards the second fixing piece 3 after the adhesive layer 101 of the dressing is adhered to the patient's scalp to clamp the patient's hair. The third fixing piece 4 and the second fixing piece 3 are connected to the patient's hair by the adhesion of the third adhesive layer 401. That is, the dressing body 1 is fixed by the cooperation of the third fixing piece 4, the first fixing piece 2, the second fixing piece 3 and the patient's hair, which improves the stability of the dressing body 1 during use and reduces the occurrence of falling off. The three fixation pieces work together in sequence to form an extremely stable three-dimensional, multi-dimensional fixation structure. In actual use, this provides continuous wound protection for patients. This fixation method can also reduce the stimulation of the wound caused by the movement of the main dressing 1, and reduce the patient's pain.

[0028] Furthermore, such as Figure 5 As shown, the dressing body 1, the first fixing piece 2, the second fixing piece 3, and the third fixing piece 4 are arranged in a grid pattern. The dressing body 1 and the second fixing piece 3 are diagonally arranged, and the first fixing piece 2 and the third fixing piece 4 are diagonally arranged. From the perspective of uniform distribution of fixing force, the grid pattern and diagonal arrangement allow each fixing piece to be stacked upwards in sequence and clamp the hair, making the dressing body 1 more secure and enhancing the overall fixing effect. This is more suitable for patients with hair. The dressing body 1, the first fixing piece 2, and the second fixing piece 3 are provided with broken dotted lines or point breaks at the connection points to facilitate folding.

[0029] Furthermore, such as Figure 5 As shown, a gap 6 is provided between the third fixing piece 4 and the dressing body 1. The gap 6 reduces the impact on the folding operation during use caused by the third fixing piece 4 being connected to the dressing body 1.

[0030] Example 3 further optimizes the head trauma dressing structure provided in Example 1 or 2, specifically, as follows: Figures 1-2 As shown, release paper 5 is provided on the dressing adhesive layer 101, the first adhesive layer 201, the second adhesive layer 301 and the third adhesive layer 401. The release paper 5 is used to protect the dressing adhesive layer 101, the first adhesive layer 201, the second adhesive layer 301 and the third adhesive layer 401 before use, and to reduce the possibility of contamination before use. The first adhesive layer 201, the second adhesive layer 301 and the third adhesive layer 401 are all made of medical pressure-sensitive adhesive.

[0031] Furthermore, such as Figures 1-2 As shown, a tear-off handle 501 is fixedly connected to the side of the release paper 5. The tear-off handle 501 is used to assist in tearing off the release paper 5. The tear-off handle 501 provides a convenient point of force for tearing off the release paper 5. In actual operation, medical staff or patients can more easily tear off the release paper 5 through the tear-off handle 501.

[0032] When using, first remove the hair around the wound on the patient's head to expose the wound. After suturing the wound and applying medication, peel off the release paper 5 on the adhesive layer 101 of the dressing, attach the adhesive layer 101 of the dressing to the patient's scalp, and make the dressing body 1 cover the wound. Peel off the release paper 5 on the first adhesive layer 201 and push the hair around the dressing body 1 toward the top of the dressing body 1. Then, stick the first adhesive layer 201 to the top of the dressing body 1, and stick the hair between the dressing body 1 and the first fixing piece 2. Peel off the release paper 5 on the second adhesive layer 301 and move the surrounding hair toward the first fixing piece 2. Then stick the second adhesive layer 301 to the top of the first fixing piece 2 so that the hair is stuck between the second fixing piece 3 and the first fixing piece 2. Remove the release paper 5 from the third adhesive layer 401 and move the surrounding hair toward the second fixation piece 3. Then, stick the third adhesive layer 401 to the top of the second fixation piece 3, so that the hair is stuck between the third fixation piece 4 and the second fixation piece 3, so that the application can form an effective fixation with the patient's scalp and hair when in use, without the need for an additional headgear.
