Abstract

This utility model relates to the field of adhesive technology and discloses a novel environmentally friendly, hypoallergenic, and breathable adhesive, comprising a first dressing, with second dressings fixedly fitted inside both sides of the first dressing. This utility model, by setting up the second dressing, a first extension strip, a C-shaped adhesive tape, and a first adhesive strip, allows for bending of the second dressing when the wound is on a finger or similar area. Because the first extension strip is made of aluminum, the second dressing remains fixed after bending and deformation, thus adapting to the area requiring adhesion. The C-shaped adhesive tape and the first adhesive strip then adhere to the skin for fixation. Even when the tip of the C-shaped adhesive tape detaches, the combination of the first adhesive strip and the side of the C-shaped adhesive tape prevents dust and bacteria from entering, thus preventing decreased adhesion strength and wound infection. Furthermore, the acrylic adhesive has low hypoallergenicity and strong weather resistance, making it suitable for long-term application.

Description

Technical Field

[0001] This utility model relates to the field of adhesive technology, and more specifically, to a novel environmentally friendly, hypoallergenic, and breathable adhesive. Background Technology

[0002] As a medical adhesive material specifically designed for wound care, adhesive dressings are mainly composed of a biocompatible adhesive layer and a functionalized substrate. Their core characteristics include: gentle adhesion, ensuring firm fixation while preventing tearing; breathability and moisture permeability, maintaining a balanced wound microenvironment; and differentiated design, such as a structure with high adhesion at the edges and low adhesion in the center to prevent wound adhesion. In wound dressings, adhesive dressings not only provide mechanical fixation but also integrate hemostatic, antibacterial, or healing-promoting functions, serving as a key intelligent interface connecting dressings and skin. Modern medical adhesive dressings must pass ISO 10993 biocompatibility certification and possess both low allergenicity and dynamic compliance.

[0003] In daily life and work, after minor cuts caused by accidents, medical adhesive tape is often used to cover the wound and apply medication. However, while existing adhesive tapes have basic functions of covering and applying medication, their simple structure, relying solely on the adhesive tape at the bottom to adhere to the skin, often leads to problems. This is because the tape cannot conform to the shape of the skin around the wound, causing wrinkles that allow dust and bacteria to enter through the gaps. This results in decreased adhesiveness, wound infection, and slow healing. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a new type of environmentally friendly, hypoallergenic, and breathable adhesive patch with the advantage of good skin compatibility.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel environmentally friendly, hypoallergenic, and breathable adhesive patch, comprising a first dressing, with second dressings fixedly sleeved inside the left and right sides of the first dressing, a first extension strip fixedly connected to the inner cavity of the second dressing, the first extension strip being made of aluminum, a C-shaped adhesive tape fixedly connected to the bottom of the second dressing, and a first adhesive strip fixedly installed on the bottom of the second dressing inside the C-shaped adhesive tape, both the C-shaped adhesive tape and the first adhesive strip being made of acrylic adhesive.

[0006] As a preferred embodiment of this utility model, an annular adhesive tape is fixedly connected around the bottom of the first dressing, and a second adhesive strip is fixedly connected to both the left and right sides of the bottom of the first dressing.

[0007] As a preferred embodiment of this utility model, a breathable and waterproof pad is fixedly connected to the inside of the top of the first dressing, and the breathable and waterproof pad is made of polyurethane.

[0008] As a preferred embodiment of this utility model, an absorbent pad is fixedly installed inside the first dressing. The absorbent pad is made of alginate, and the bottom of the absorbent pad is fixedly connected to the top of the breathable and waterproof pad.

[0009] As a preferred embodiment of this utility model, a medicated pad is fixedly connected to the bottom of the inner cavity of the first dressing, and the top of the medicated pad is fixedly connected to the bottom of the absorbent pad.

[0010] As a preferred embodiment of this utility model, a second extension strip is fixedly installed on both the front and rear sides inside the first dressing strip, and the outer surface of the second extension strip is fixedly sleeved with the inside of the absorbent pad.

[0011] As a preferred embodiment of this utility model, a reinforcing strip is fixedly connected to the top of the second dressing strip, and the inner side of the reinforcing strip is fixedly connected to the top of the first dressing strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a second dressing, a first extension strip, a C-shaped adhesive tape, and a first adhesive strip, allows the second dressing to bend when the wound is on a finger or other area. Since the first extension strip is made of aluminum, the second dressing remains fixed after bending and deformation, thus adapting to the area to be adhered to. Then, the C-shaped adhesive tape and the first adhesive strip are used to adhere to the skin for fixation. When the top of the C-shaped adhesive tape detaches, the combination of the first adhesive strip and the side of the C-shaped adhesive tape can also prevent dust and bacteria in the air from entering, thus preventing a decrease in adhesion strength and wound infection. At the same time, the acrylic adhesive has the characteristics of low allergenicity and strong weather resistance, making it suitable for long-term application.

[0013] 2. This utility model incorporates a medicated pad, an absorbent pad, a breathable and waterproof pad, and a second extension strip. When the wound surface is uneven, pressing the second extension strip causes it to bend the absorbent pad and the medicated pad, thus adapting to the shape of the wound. This ensures that the medicated pad and the absorbent pad cover the wound area while providing sufficient strength support. When the wound oozes fluid, the alginate in the absorbent pad undergoes ion exchange with the body fluid, forming a hydrophilic gel that activates platelets, accelerates thrombin generation, and helps the wound heal. The breathable and waterproof pad is made of polyurethane, whose micropores prevent water molecules from passing through while leaving water vapor molecules unaffected, achieving both breathability and excellent waterproof performance.

[0016] 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.

[0017] like Figures 1 to 6 As shown, this utility model provides a novel environmentally friendly, hypoallergenic, and breathable adhesive patch, including a first dressing 1. Second dressings 2 are fixedly sleeved inside both the left and right sides of the first dressing 1. A first extension strip 3 is fixedly connected to the inner cavity of the second dressing 2. The first extension strip 3 is made of aluminum. A C-shaped adhesive tape 4 is fixedly connected to the bottom of the second dressing 2. A first adhesive strip 5 is fixedly installed inside the C-shaped adhesive tape 4 at the bottom of the second dressing 2. Both the C-shaped adhesive tape 4 and the first adhesive strip 5 are made of acrylic adhesive.

[0018] Because the No. 1 extension strip 3 is made of aluminum, the second dressing 2 can be bent and deformed and remain fixed, thus adapting to the area to be pasted. Then, it is fixed to the skin by the C-shaped tape 4 and the first adhesive strip 5, preventing dust and bacteria in the air from entering, which would lead to a decrease in adhesion strength and wound infection. At the same time, the acrylic adhesive has the characteristics of good breathability, low allergenicity and strong weather resistance, making it suitable for long-term application.

[0019] Among them, the bottom of the first dressing 1 is fixedly connected with annular adhesive tape 6 around the perimeter, and the bottom of the first dressing 1 is fixedly connected with second adhesive strips 7 on both the left and right sides.

[0020] The ring tape 6 and the second adhesive strip 7 are made of silicone adhesive. This design, compared with traditional full-coverage adhesive, uses less adhesive while ensuring the same adhesive strength, thus improving environmental friendliness.

[0021] Among them, the top of the first dressing 1 is fixedly connected to a breathable and waterproof pad 10, which is made of polyurethane.

[0022] Polyurethane is characterized by its softness and high elasticity. Microporous films made from polyurethane can achieve excellent waterproof properties while maintaining good breathability.

[0023] The first dressing 1 has an absorbent pad 9 fixedly installed inside. The absorbent pad 9 is made of alginate, and the bottom of the absorbent pad 9 is fixedly connected to the top of the breathable and waterproof pad 10.

[0024] When in contact with wound exudate, alginate undergoes ion exchange with the body fluid, forming a hydrophilic gel while simultaneously activating platelets and accelerating thrombin production.

[0025] The bottom of the inner cavity of the first dressing 1 is fixedly connected to a medicated pad 8, and the top of the medicated pad 8 is fixedly connected to the bottom of the absorbent pad 9.

[0026] When the medicated pad 8 comes into contact with the wound, it will cover and seal the wound, preventing the wound from being directly exposed to the air. At the same time, the medicine contained in the medicated pad 8 will help the wound heal.

[0027] Among them, the front and rear sides of the first dressing strip 1 are fixedly installed with the second extension strip 11, and the outer surface of the second extension strip 11 is fixedly sleeved with the inside of the absorbent pad 9.

[0028] When the wound surface is uneven, pressing the second extension strip 11 can cause the second extension strip 11 to bend the absorbent pad 9 and the medicated pad 8, thereby adapting to the shape of the wound surface and ensuring that the medicated pad 8 and the absorbent pad 9 cover the wound area while providing a certain strength support.

[0029] The top of the second dressing 2 is fixedly connected to a reinforcing strip 12, and the inner side of the reinforcing strip 12 is fixedly connected to the top of the first dressing 1.

[0030] The design of the reinforcing strip 12 improves the connection strength between the left and right sides of the second tape 2, and avoids metal fatigue caused by repeated bending of the first extension strip 3 during long-term use.

[0031] Working principle and usage process of this utility model: When wound coverage and medication application are required, align the bottom of the medicated pad 8 with the wound and press lightly to fix the ring tape 6 and the second adhesive strip 7 to the skin around the wound. When the wound is uneven, such as at a joint, press the second extension strip 11 to cause the absorbent pad 9 and the medicated pad 8 to bend, thus adapting to the shape of the wound and ensuring that the medicated pad 8 and absorbent pad 9 cover the wound area while providing a certain strength support. When the wound oozes, the alginate in the absorbent pad 9 undergoes ion exchange with the body fluid, forming a hydrophilic gel while activating platelets, accelerating thrombin generation, and helping the wound heal. The breathable and waterproof pad 10 is made of polyurethane. The micropores of polyurethane prevent water molecules from passing through, while water vapor molecules are unaffected, achieving good waterproof performance while being breathable.

[0032] When the wound is on a finger or other area, press the left and right ends of the second dressing 2 to bend it. Since the first extension strip 3 is made of aluminum, the second dressing 2 remains fixed after bending and deforming, thus adapting to the area to be pasted. Then, it is fixed to the skin by the adhesion of the C-shaped tape 4 and the first adhesive strip 5. When the top of the C-shaped tape 4 detaches, the combination of the first adhesive strip 5 and the side of the C-shaped tape 4 can also prevent dust and bacteria in the air from entering, which would reduce the adhesion strength and cause wound infection. At the same time, acrylic adhesive has the characteristics of good breathability, low allergenicity and strong weather resistance, making it suitable for long-term application. Compared with traditional adhesive tape, it uses less adhesive and is more environmentally friendly.
