Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a protective dressing for ear wounds. Background Technology

[0002] The auricle, located on either side of the skull and protruding from the skin, is easily injured during falls, blows, traffic accidents, and other traumatic injuries, requiring surgical procedures such as debridement and suturing. Like wounds on other parts of the body, ear wounds also require dressings for protection. Due to the ear's unique outward-expanding anatomical structure and uneven surface, ordinary skin dressings are often insufficient to completely cover the wound, frequently requiring multiple layers of gauze. This presents several problems, including complex procedures, difficulty in achieving a perfect fit, and impact on appearance. Furthermore, in otolaryngological surgeries, including those for preauricular fistulas, auricular cysts, mastoidectomy, and accessory auricle repair, postoperative dressing changes and monitoring are necessary to promote wound healing and prevent infection. These procedures also require dressings to protect the wound.

[0003] Currently, there is a lack of surgical dressings specifically designed for ear bandaging on the market. Traditional skin dressings are flat and difficult to fit completely to ear wounds. This presents several drawbacks, such as: 1. Difficulty in fitting the auricle wound, leaving gaps in the dressing and increasing the risk of reinfection; 2. Ordinary skin dressings are difficult to secure to the ear, easily falling off and causing wound exposure and infection; 3. Ordinary skin dressings often require the use of additional sterile gauze, making bandaging complex, dressing changes cumbersome, and time-consuming; 4. Excessive gauze bandaging affects the patient's facial appearance, or bandaging too tightly causes discomfort, restricts ventilation, and wastes dressings to some extent.

[0004] To address the aforementioned problems, this invention proposes a self-adhesive surgical dressing for the ear, which is more suitable for the appearance of the ear and provides better protection and fixation of the wound. Utility Model Content

[0005] Technical problem solved: In response to the above-mentioned technical problems, this utility model provides a self-adhesive ear surgical dressing with a simple design and moderate size. Compared with traditional bandaging methods, it is more suitable for the ear in terms of functionality and aesthetics, which can reduce the patient's discomfort and anxiety about the wound, while also making it easier for clinicians to observe the wound exudation.

[0006] Technical solution: A self-adhesive ear surgical dressing includes a waterproof adhesive layer, the adhesive surface of which is provided with a protective layer, the waterproof adhesive layer includes a front part and a back part, the adhesive surface of which is provided with a dressing layer, the dressing layer being located between the waterproof adhesive layer and the protective layer.

[0007] Preferably, the waterproof adhesive layer is generally long "T" shaped, with both the front and rear parts being rounded rectangles, and the width of the front part being greater than the width of the rear part.

[0008] Preferably, the adhesive side of the waterproof adhesive layer is applied to human skin, and the dressing layer is placed at the wound site.

[0009] Preferably, the size of the dressing layer is adapted to the ear wound surface.

[0010] Preferably, the dressing layer has an absorbent layer inside.

[0011] Preferably, the protective layer comprises two protective pages connected by Velcro.

[0012] Beneficial effects: This novel self-adhesive ear surgical dressing can adapt to the physiological curvature of the patient's ear, protecting the ear wound. It accommodates different ear sizes, thus fixing the dressing to the ear and achieving front-to-back fixation, thereby improving the stability of the bandage and simplifying the fixation process. This effectively saves clinicians time on dressing changes and reduces dressing costs.

[0013] The absorbent layer inside the dressing has a certain water absorption capacity, which can absorb the fluid oozing from the wound, keep the wound dry and clean, and help promote wound healing.

[0014] This utility model uses disposable aseptic packaging, which is simple to package and enables one-step dressing change, making it convenient for patients to change dressings at home;

[0015] This utility model of wound dressing has a simple design and moderate size. It is more aesthetically pleasing than traditional bandaging methods, can reduce patient discomfort and anxiety about the wound, and facilitates clinicians to observe wound exudation. Attached Figure Description

[0020] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings. Example 1

[0021] Reference Figure 1 and Figure 2 A self-adhesive ear surgical dressing includes a waterproof adhesive layer 1, wherein the inner layer of the waterproof adhesive layer 1 is an adhesive surface and the outer layer is a waterproof surface, both of which are made of medical-grade materials; the adhesive surface of the waterproof adhesive layer 1 is provided with a protective sheet layer 3; the waterproof adhesive layer includes a front part 1-1 and a rear part 1-2; the adhesive surface of the front part 1-1 is provided with a dressing layer 2, which is located between the waterproof adhesive layer 1 and the protective sheet layer 3.

[0022] The waterproof adhesive layer 1 is generally long "T" shaped, with the front part 1-1 and the rear part 1-2 both being rounded rectangles. The width of the front part 1-1 is greater than the width of the rear part 1-2. The adhesive surface of the waterproof adhesive layer 1 is directly applied to human skin to fix it in place, and the waterproof surface has waterproof and dustproof functions.

[0023] The aforementioned dressing layer 2 is placed over the wound. The size of dressing layer 2 is adapted to common ear wounds, and is slightly larger than the wound size to ensure that the dressing can stably and completely cover the ear wound. The dressing layer 2 has an absorbent layer inside, which can absorb the fluid seeping from the wound, keep the wound dry and clean, and help promote wound healing.

[0024] The aforementioned protective layer 3 includes two protective sheets connected by Velcro. Before use, the self-adhesive ear dressing is opened to expose the dressing layer 2, making it easier to place the dressing layer 2 on the wound.

[0025] Reference Figure 3 Regardless of whether the wound is in front of, on, or behind the ear, self-adhesive otosurgical dressings can cover the wound surface.
