Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary products technology, specifically a self-adhesive elastic medical bandage. Background Technology

[0002] Bandages play an important role in medical treatment, often used to wrap and protect wounds after fractures and ligament injuries. Bandages are generally made of gauze or cotton, and compared to traditional gauze, they are more secure and practical.

[0003] For example, Chinese invention patent CN222657319U, published on March 5, 2025, discloses a medical antibacterial bandage, comprising a bandage body, an antibacterial layer on the surface of the bandage body, a surface breathable layer on the surface of the antibacterial layer, and a tearable dustproof layer on the surface of the surface breathable layer; the bandage body includes an inner composite gauze layer and an outer composite gauze layer, with a set of uniformly distributed drying layers between the inner and outer composite gauze layers. This invention features antibacterial and breathable properties while maintaining dryness.

[0004] As can be seen from the above patents, the medical antibacterial bandage is antibacterial, breathable, and can keep dry. However, it suffers from the problem of being difficult to self-adhere and fix, and the bandage is prone to loosening, breaking, or even falling off, affecting its use. Therefore, this invention provides a self-adhesive elastic medical bandage to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a self-adhesive elastic medical bandage.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A self-adhesive elastic medical bandage includes a bandage body, wherein the bandage body is provided with a first gauze layer, an antibacterial layer, a second gauze layer and an adhesive layer from the inside out; the adhesive layer is an elastic fabric coated with medical pressure-sensitive adhesive; the front and rear edges of the first gauze layer are provided with hook and loop fasteners, and the front and rear edges of the adhesive layer are provided with hook and loop fasteners with rough edges, wherein the positions of the hook and loop fasteners and the hook and loop fasteners are corresponding and their specifications are compatible.

[0007] Preferably, a protective film layer is provided on the inner surface of the first gauze layer.

[0008] Preferably, the Velcro fleece surface is evenly distributed at equal intervals on the front and rear edges of the first gauze layer.

[0009] Preferably, the antibacterial layer is a nano-silver ion antibacterial layer.

[0010] Preferably, the first gauze layer, the antibacterial layer, the second gauze layer, and the adhesive layer are all densely covered with pores.

[0011] The beneficial effects of this utility model are: This medical bandage is constructed by using an adhesive layer coated with medical-grade pressure-sensitive adhesive as its outermost layer. When wrapping the bandage around a wound, the pressure-sensitive adhesive provides the first layer of self-adhesion and fixation. A second layer of self-adhesion and fixation, further reinforced by the combination of the plush and burr sides of Velcro, is then achieved. This application solves the problem of poor self-adhesion and fixation in medical bandages, achieving double self-adhesion and reinforcement, thus facilitating their use. Attached Figure Description

[0021] Reference Figure 1-3The present invention discloses a self-adhesive elastic medical bandage, comprising a bandage body 1, a hook and loop fleece surface 2, a hook and loop burr surface 3, and a protective film layer 4; the bandage body 1 is provided with a first gauze layer 11, an antibacterial layer 12, a second gauze layer 13, and an adhesive layer 14 from the inside to the outside. The first gauze layer 11 fits the wound and is densely covered with pores to allow the wound to breathe and prevent inflammation. Velcro loops 2 are provided on the front and rear edges of the first gauze layer 11 for reinforcement by using Velcro to adhere to the edges. The antibacterial layer 12 is a nano-silver ion antibacterial layer that can inhibit bacteria and improve the medical value of the medical bandage. The second gauze layer 13 is both breathable and serves to block the antibacterial layer 12 and the adhesive layer 14. The adhesive layer 14 is an elastic fabric coated with medical pressure-sensitive adhesive, which mainly functions as a self-adhesive due to the adhesive effect of the medical pressure-sensitive adhesive. Velcro burrs 3 are provided at the corresponding positions of the front and rear edges of the adhesive layer 14 and the Velcro loops 2. The Velcro burrs 3 and the Velcro loops 2 of suitable specifications are used together to achieve self-adhesion and reinforcement of the first gauze layer 11 and the adhesive layer 14 at the edges.

[0022] In an optional embodiment, a protective film layer 4 is provided on the inner surface of the first gauze layer 11, which can play a protective and barrier role when not in use, and can also prevent dust; it can be torn off and used when in use.

[0023] In an optional embodiment, the Velcro plush surface 2 is evenly distributed at equal intervals on the front and rear edges of the first gauze layer 11. On the one hand, the area where the Velcro plush surface 2 is not provided on the edge of the first gauze layer 11 can be breathable while maintaining high elasticity. On the other hand, it is convenient to cut the bandage at the area where the Velcro plush surface 2 is not provided after the medical bandage is wrapped, thus improving convenience.

[0024] In an optional embodiment, the first gauze layer 11, the antibacterial layer 12, the second gauze layer 13, and the adhesive layer 14 are all densely covered with pores to improve the breathability of the medical bandage and prevent wound inflammation.

[0025] The process of using this utility model: Apply the medical bandage close to the wound, peel off the protective film layer 4, and then apply the first gauze layer 11 to the wound and wrap it around. After wrapping once, the second layer of the bandage body 1 presses on the first layer of the bandage body 1, that is, the first gauze layer 11 of the second layer of the bandage body 1 presses on the adhesive layer 14 of the first layer of the bandage body 1. The medical pressure-sensitive adhesive coated in the middle of the adhesive layer 14 achieves the first layer of self-adhesion and fixation of the medical bandage to the first gauze layer 11 of the second layer of the bandage body 1 under pressure. At the same time, the Velcro plush surface 2 on the front and rear edges of the first gauze layer 11 of the second layer of the bandage body 1 and the Velcro burr surface 3 on the front and rear edges of the adhesive layer 14 of the first layer of the bandage body 1 work together to achieve the second layer of self-adhesion and fixation of the medical bandage and reinforce it.

[0026] Of course, the embodiments described in this specific implementation are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
