Description

Technical Field

[0001] This utility model relates to the field of adhesive bandage technology, and in particular to an anti-wrinkle and anti-crack adhesive bandage. Background Technology

[0002] Band-aids are widely known and play an important role in daily wound care. Structurally, they generally consist of a long strip of adhesive tape as a base, with a small piece of gauze (or medicated gauze soaked in specific medications) attached to the center. Essentially, they are a type of medical dressing, composed of medical tape, an absorbent pad, and a protective membrane. Some products also add medicated ingredients to enhance their therapeutic effect. Band-aids have become a common household item due to their numerous advantages. They effectively stop bleeding through moderate pressure; covering the wound creates a relatively isolated environment, protecting the wound and reducing the possibility of infection from external pathogens, thus promoting healing. Furthermore, band-aids are small and portable, easy to use, and convenient for both home use and travel. Their excellent breathability ensures the skin around the wound can breathe normally, demonstrating reliable therapeutic effects in practical applications.

[0003] Traditional adhesive bandages, due to their simple design, tend to wrinkle during daily activities such as joint bending, stretching, and skin stretching. This not only affects their protective effect on the wound but can also cause secondary damage to the surrounding skin due to friction from the wrinkles, and may even lead to the bandage breaking, exposing the wound to the external environment and increasing the risk of infection. Furthermore, existing adhesive bandages are poorly designed to prevent wrinkling and tearing, failing to adapt well to skin deformation during activity and maintaining a stable, intact fit for extended periods. Consequently, they cannot provide continuous and reliable protection for the wound, hindering the healing process and failing to meet people's needs for anti-wrinkling and stable adhesive bandages.

[0024] 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.

[0025] Reference Figure 1-3This utility model provides an embodiment of an anti-wrinkle adhesive bandage, comprising a bandage body 1, with a gel layer 2 disposed at the upper part of the center of the bandage body 1. The gel layer 2 is made of highly absorbent carbomer gel material, which can quickly absorb wound exudate, keep the wound dry, create a good moist environment for wound healing, prevent bacterial growth due to the accumulation of wound exudate, and also help reduce edema of the skin around the wound. A hemostatic layer 3 is disposed above the gel layer 2, made of chitosan fiber material. Chitosan fiber has good hemostatic effect, promoting platelet aggregation and activation of coagulation factors, thereby quickly stopping wound bleeding. Furthermore, chitosan fiber also has certain antibacterial properties, further reducing the risk of wound infection. An antibacterial layer 4 is disposed above the hemostatic layer 3, made of silver ion fiber material. Silver ions have strong antibacterial ability, continuously inhibiting the growth and reproduction of bacteria around the wound, effectively preventing wound infection, and providing a clean and sterile environment for wound healing. Absorbent layers 5 are provided on both sides of the hemostatic layer 3 and the antibacterial layer 4. These absorbent layers 5 are made of highly absorbent cellulose fibers, capable of absorbing various fluids exuded from the wound, including blood and tissue fluid, keeping the bandage dry and clean, preventing fluid accumulation that could lead to poor adhesion or bacterial growth. Their high absorbency also helps maintain the dryness and comfort of the skin around the wound. The absorbent layer 5 is located on the bandage body 1, and multiple wedge-shaped notches 6 are spaced apart along its inclined surface. The design of these wedge-shaped notches 6 is one of the key innovations of this invention. When the bandage is applied to the skin, especially in active areas such as joints, the wedge-shaped notches 6 allow the bandage to naturally deform with the stretching and bending of the skin, effectively preventing wrinkles and tears caused by skin movement. This greatly improves the stability and durability of the bandage, ensuring it maintains good protective properties throughout the wound healing process.

[0026] The upper ends of the adhesive bandage body 1 are provided with release paper 7, which protects the adhesive layer when the adhesive bandage is not in use, preventing it from becoming contaminated or losing its adhesiveness. The ends of the adhesive bandage body 1 are provided with adhesive layers 8, which are made of acrylic pressure-sensitive adhesive. This adhesive has good adhesion, ensuring the adhesive bandage adheres firmly to the skin without causing excessive irritation. It is also relatively easy to remove the adhesive bandage without causing pain or damage to the skin. The adhesive bandage body 1, from top to bottom, includes an anti-adhesion layer 10, a healing-promoting and pain-relieving layer 11, a support layer 12, and a waterproof layer 13. The anti-adhesion layer 10 is made of silicone material, which effectively prevents the adhesive bandage from adhering to the wound and surrounding skin, avoiding damage to newly formed tissue when changing the adhesive bandage and reducing the risk of secondary injury during the wound healing process. The healing and pain-relieving layer 11 is made of polyacrylamide hydrogel, which promotes wound healing and reduces pain. It provides a suitable microenvironment for cell growth and repair, accelerating the wound healing process while reducing patient pain. The support layer 12 is made of spandex elastic fabric, providing appropriate support to the wound, especially in active areas such as joints. The elasticity of the spandex fabric can stretch and contract with joint movement, ensuring a good fit without excessive pressure or stretching on the wound, providing stable protection. The waterproof layer 13 is made of polyurethane and is located on the outermost layer. It effectively prevents external moisture from penetrating, preventing infection from contact with water. Whether washing hands or bathing in daily life, or in humid environments, it ensures that the inside of the bandage remains dry, providing reliable protection for wound healing.

[0027] In addition, multiple ventilation holes 9 are provided on the adhesive bandage body 1 and the adhesive layer 8, and the ventilation holes 9 penetrate through the adhesive bandage body 1 and the adhesive layer 8. The presence of ventilation holes 9 ensures that the skin around the wound can breathe normally, which helps maintain the physiological function of the skin, further promotes wound healing, and also reduces skin discomfort and bacterial growth caused by a hot and humid environment.

[0028] Working principle: When using the anti-wrinkle and anti-crack adhesive bandage of this utility model, first peel off the release paper 7, align the center of the bandage with the wound, and then gently press the adhesive layer 8 to firmly adhere it to the skin around the wound. During daily activities, such as joint movement or skin stretching, due to the special design of the wedge-shaped notch 6 on the absorbent layer 5, the bandage can naturally stretch and bend with the deformation of the skin without wrinkling or tearing. At the same time, the appropriate support provided by the support layer 12 ensures that the bandage always adheres to the wound during activities without shifting or lifting.

[0029] The exudate from the wound is first rapidly absorbed by the gel layer 2, keeping the wound dry. Excess fluid is absorbed and stored by the absorbent layer 5, preventing fluid buildup inside the bandage. The antibacterial layer 4 continuously exerts its antibacterial effect, inhibiting bacterial growth. The anti-adhesion layer 10 prevents the bandage from sticking to the wound. The healing-promoting and pain-relieving layer 11 creates favorable conditions for wound healing. The waterproof layer 13 blocks external moisture from entering, and the vents 9 ensure normal skin respiration. These layers work together synergistically to provide a comprehensive, stable, safe, and healing-promoting environment for the wound, effectively addressing the shortcomings of traditional bandages in preventing wrinkling and wound care, and meeting people's higher performance requirements for bandages.

[0030] Through the above design, this novel anti-wrinkle and anti-crack adhesive bandage has significant advantages in wound protection, anti-wrinkle and anti-crack performance, stability, breathability, waterproofness, and promotion of wound healing, providing users with a higher quality and more reliable wound care experience.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
