Description

Technical Field

[0001] This application relates to the field of medical supplies technology, specifically a novel medical tape. Background Technology

[0002] Currently, medical tapes commonly found on the market can be mainly divided into four types based on the adhesive coating method of the backing material: full-coat, perforated, striped, and mesh. These types of medical tapes have their own application characteristics in different clinical situations. For example, full-coat tapes are widely used in outdoor emergency care due to their excellent waterproof performance, while perforated tapes are suitable for long-term use due to their better breathability. However, with the continuous advancement of medical technology and patient needs, existing medical tapes have gradually revealed some shortcomings, such as skin irritation and insecure fixation, which has spurred the research and development of new types of medical tapes.

[0003] Full-coat tape achieves strong adhesion by evenly applying a layer of pressure-sensitive adhesive to its surface. While this type of tape is highly adhesive, it can easily cause skin allergies or damage to users. Perforated tape increases breathability and comfort by creating tiny pores on the tape, but this reduces the overall strength and durability of the tape. Striped tape sets continuous or intermittent linear pressure-sensitive adhesive areas on the adhesive surface, attempting to balance adhesion and breathability, but it still cannot fully meet the needs of certain specific conditions in actual use. Mesh tape uses a mesh structure design to improve the breathability of the tape, but due to its structure, its fixing effect is often unsatisfactory.

[0004] In summary, various types of medical tapes on the market have their own advantages and disadvantages, but they generally have the following problems: First, they are not suitable for sensitive skin and can easily cause adverse reactions such as contact dermatitis; second, some products have poor fixation effects, especially in motion, where they are difficult to maintain stability; and third, due to limitations in materials or design, some types of tapes do not perform well in terms of breathability and moisture permeability. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a novel medical tape that significantly improves the breathability and moisture permeability of the medical tape, reducing potential skin problems during prolonged use.

[0006] To achieve the above objectives, this application provides the following technical solution: a novel medical tape, comprising a medical tape body, the medical tape body including an outermost breathable protective layer, the breathable protective layer being a layer made of polyester fiber and nylon blended fabric, a functional surface layer above the breathable protective layer, an intermediate buffer layer hot-pressed and laminated below the breathable protective layer, the intermediate buffer layer being made of EVA foam material, a bottom pressure-sensitive adhesive layer bonded below the intermediate buffer layer, the bottom pressure-sensitive adhesive layer being made of imported acrylic adhesive, and a removable release paper below the bottom pressure-sensitive adhesive layer.

[0007] Through the above-mentioned design, by setting a breathable protective layer and a bottom pressure-sensitive adhesive layer, this medical tape significantly improves breathability and moisture permeability, effectively reducing potential skin problems during prolonged wear. The introduction of an intermediate buffer layer not only ensures the strong fixing ability of the medical tape itself but also reduces impact and pressure on the skin, enhancing wearing comfort. For easy storage and transportation, it is also equipped with anti-stick paper to prevent the tape from sticking together when not in use. The functional surface layer optimizes waterproof and antibacterial properties, making it more practical.

[0008] Furthermore, the functional surface layer includes an antibacterial coating sprayed onto the upper surface of the breathable protective layer, wherein the antibacterial coating is a silver ion coating.

[0009] The above methods can kill or inhibit the survival of pathogenic microorganisms on the surface of the medical tape, reducing the risk of infection during use.

[0010] Furthermore, the upper surface of the antibacterial coating is coated with a waterproof coating, which is a fluoride coating.

[0011] The above solution provides additional waterproofing to the medical tape, making it suitable for medical environments requiring humidity isolation.

[0012] Furthermore, the thickness of the breathable protective layer is 0.1 mm.

[0013] The above solution limits the size of the breathable protective layer, ensuring it is lightweight while maintaining good moisture-wicking properties.

[0014] Furthermore, the density of the EVA foam material in the intermediate buffer layer is approximately 0.06 g / cm³.

[0015] The above solution ensures that the elastic recovery rate of the intermediate buffer layer is over 95%, thus optimizing the performance.

[0016] Furthermore, the interior of the intermediate buffer layer is filled with uniformly distributed micro-drug capsules.

[0017] The above approach can be used to slowly release anti-inflammatory or analgesic drugs, reducing the frequency of medication changes for patients.

[0018] Furthermore, the interior of the bottom pressure-sensitive adhesive layer contains aloe vera extract.

[0019] The above methods can reduce skin irritation from long-term use.

[0020] Furthermore, two pull strips are fixedly connected to the bottom surface of the release paper.

[0021] The above method allows for easy and quick removal of the release paper from the bottom of the pressure-sensitive adhesive layer, making it convenient to use.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This novel medical tape significantly improves breathability and moisture permeability by incorporating a breathable protective layer and a bottom pressure-sensitive adhesive layer, reducing potential skin problems during prolonged use. The aloe vera extract in the bottom pressure-sensitive adhesive layer effectively reduces skin irritation from long-term use. The introduction of a middle buffer layer design allows the tape to maintain strong adhesion while reducing pressure on the skin, enhancing the user's wearing experience. Micro-drug capsules in the middle buffer layer enable the slow release of anti-inflammatory or analgesic drugs, reducing local inflammation and pain. Finally, the included anti-stick paper facilitates easy storage and transportation of the medical tape. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a novel medical tape includes a medical tape body 1, which includes an outermost breathable protective layer 101 with a thickness of 0.1 mm. This design limits the size of the breathable protective layer 101, ensuring it is thin yet possesses good moisture-wicking properties. The breathable protective layer 101 is made of a blended fabric of polyester fiber and nylon. A functional surface layer 2 is located above the breathable protective layer 101. A middle buffer layer 102, made of EVA foam material, is heat-pressed and laminated below the breathable protective layer 101. The density of the EVA foam material in layer 102 is about 0.06 g / cm³, which can ensure that the elastic recovery rate of the middle buffer layer 102 is over 95%, effectively absorbing pressure, reducing pressure damage to the skin, and optimizing the use effect. The bottom pressure-sensitive adhesive layer 103 is bonded to the bottom of the middle buffer layer 102. The bottom pressure-sensitive adhesive layer 103 is made of imported acrylic adhesive, with an initial tack of ≥8N / 25mm and a holding power of >72 hours. The material of the bottom pressure-sensitive adhesive layer 103 ensures sufficient adhesion without easily falling off, while also avoiding skin discomfort caused by prolonged wear.

[0032] Please see Figure 2 , Figure 3 and Figure 4 The intermediate buffer layer 102 is filled with uniformly distributed micro-drug capsules 104. The encapsulation of the micro-drug capsules 104 can use biodegradable materials, such as polylactic acid-glycolic acid copolymer (PLGA), to microencapsulate the drug particles and form micro-drug capsules 104. This can improve the stability of the drug and enable it to be used for slow-release anti-inflammatory drugs or analgesics, reducing the frequency of medication changes for patients. The bottom pressure-sensitive adhesive layer 103 contains aloe vera extract 105. By adding aloe vera extract 105, the irritation to the skin from long-term use can be reduced. Below the bottom pressure-sensitive adhesive layer 103, there is a removable release paper 3. The release paper 3 makes it easy to store and transport the medical tape body 1. The bottom surface of the release paper 3 is fixedly connected to two pull strips 4. The pull strips 4 allow the release paper 3 to be easily and quickly peeled off from the bottom surface of the bottom pressure-sensitive adhesive layer 103 for convenient use.

[0033] Please see Figure 1 , Figure 2 and Figure 3 The functional surface layer 2 includes an antibacterial coating 201 sprayed onto the upper surface of the breathable protective layer 101. The antibacterial coating 201 is preferably a silver ion coating. By providing the antibacterial coating 201, pathogenic microorganisms can be killed or inhibited from surviving on the surface of the medical tape body 1, reducing the risk of infection during use. A waterproof coating 202 is sprayed onto the upper surface of the antibacterial coating 201. The waterproof coating 202 is preferably a fluoride coating. By providing the waterproof coating 202, the medical tape body 1 can be given additional waterproof performance, making it suitable for medical environments requiring humidity isolation. The waterproof coating 202 is located on top of the antibacterial coating. The waterproof coating 202 is placed on the outermost part of the whole above 201 because its waterproof properties can prevent liquids and pathogenic microorganisms from directly contacting the surface, reducing pollution at the source, reducing excessive contact between the antibacterial coating 201 and the outside world, and prolonging the service effect of the antibacterial coating 201. The antibacterial coating 201 is located on the second outermost part of the whole because if the waterproof coating 202 fails to completely block liquids or microorganisms, the antibacterial coating 201 can further inhibit their activity. When combined with the breathable protective layer 101, its molecules can penetrate into the surface fiber pores to enhance the antiviral effect.

[0034] In this embodiment, a novel medical tape significantly improves the breathability and moisture permeability of the tape body 1 by setting a breathable protective layer 101 and a bottom pressure-sensitive adhesive layer 103, reducing potential skin problems during prolonged use. Simultaneously, the aloe vera extract 105 filled in the bottom pressure-sensitive adhesive layer 103 effectively reduces skin irritation from long-term use. The introduction of an intermediate buffer layer 102 allows the medical tape body 1 to maintain strong fixation while reducing pressure on the skin, improving the user's wearing experience. The intermediate buffer layer 102 is filled with micro-drug capsules 104, enabling the slow release of anti-inflammatory or analgesic drugs, reducing local inflammation and pain. Finally, the anti-stick paper 3 facilitates the storage and transportation of the medical tape body 1.

[0035] The working principle of the above embodiment is as follows: When the product is needed, first tear the release paper 3 with the pull strip 4 to expose the bottom pressure-sensitive adhesive layer 103, lay it flat on the target area, and gently press it to make the product adhere tightly to the skin. During this process, the breathable protective layer 101 can continuously release air to prevent heat accumulation and local temperature rise. The intermediate buffer layer 102 can effectively disperse the external pressure and reduce local pressure. The bottom pressure-sensitive adhesive layer 103 is responsible for providing stable fixation and can maintain good adhesion even when the patient is active. The filled micro-drug capsules 104 can slowly release anti-inflammatory drugs or analgesics, reducing the frequency of medication changes and optimizing the use effect of the medical tape body 1. The aloe vera extract 105 can reduce the irritation to the skin with long-term use. When the product comes into contact with water, the waterproof coating 202 can ensure the waterproof performance of the medical tape body 1. The antibacterial coating 201 can effectively perform antibacterial work, making it more practical.
