Description

Technical Field

[0001] This utility model belongs to the field of materials science and technology, and specifically relates to a water-repellent elastic breathable adhesive tape. Background Technology

[0002] Adhesive tape is often used to secure various dressings, such as gauze and bandages. It helps keep these items in place, reduces the risk of movement or falling off, protects wounds from external contamination, and promotes wound healing.

[0003] Existing adhesive tapes often suffer from poor water repellency, elasticity, and breathability. Adhesive tapes with poor water repellency are easily corroded by sweat or liquids, leading to decreased adhesion and affecting fixation or causing dressing failure. Adhesive tapes lacking sufficient elasticity cannot adapt well to body movements, which may cause them to fall off or cause discomfort when used on bending areas such as joints. Adhesive tapes with poor breathability can prevent the skin from breathing properly, easily causing stuffiness, sweat accumulation, and even skin problems. These problems often affect the effectiveness of the adhesive tape and the patient's comfort. Utility Model Content

Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention.

[0024] Example

[0025] Reference Figures 1-4 This embodiment of the present invention provides a water-repellent, elastic, and breathable adhesive tape that can achieve...

[0026] The main component 100 includes a protective layer 101, an antibacterial layer 102 fixedly connected to the bottom of the protective layer 101, a water-repellent layer 103 fixedly connected to the other side of the antibacterial layer 102, and a first adhesive layer 104 fixedly connected to the bottom of the water-repellent layer 103.

[0027] It should be noted that the PET polyester protective layer 101 can effectively prevent bacteria, viruses and other microorganisms from invading the wound and reduce the risk of infection. The antibacterial layer 102 of polyester fiber silver ion carrier material can effectively inhibit the growth and reproduction of bacteria, fungi and other microorganisms. When silver ions come into contact with the cell wall or cell membrane of microorganisms, they can penetrate the cell membrane and interfere with the cell metabolism process, leading to the death of microorganisms. The ePTFE expanded polytetrafluoroethylene microstructure of the water-repellent layer 103 has very fine pores. These pores are sufficient to block the penetration of liquid water, but allow water vapor molecules to pass through, thus effectively preventing moisture from entering while having good breathability. The first adhesive layer 104 of PSA pressure-sensitive material can quickly adhere to the skin surface under slight pressure without waiting for drying and curing time, thereby greatly improving the adhesion efficiency.

[0028] And, tensioning components 200 are provided on both sides of the main body component 100.

[0029] Furthermore, the stretching component 200 can effectively stretch each component in the main component 100, so that the adhesive strip can still maintain its adhesion even when it is stretched and deformed, ensuring that the adhesive strip will not fall off or shift due to stretching, thereby achieving the effect of maintaining stable adhesion of the adhesive strip.

[0030] Specifically, the protective layer 101 is made of PET polyester material, and the antibacterial layer 102 is made of polyester fiber silver ion carrier material.

[0031] Furthermore, the water-repellent layer 103 is made of ePTFE expanded polytetrafluoroethylene, and the first adhesive layer 104 is made of PSA pressure-sensitive adhesive.

[0032] Preferably, the main component 100 also includes an absorbent cotton 105 and a drug release layer 106 fixedly installed at the bottom of the first adhesive layer 104, with the drug release layer 106 located at the center of the absorbent cotton 105.

[0033] It should be noted that the absorbent cotton 105 is made of Rayon viscose fiber, and the drug release layer 106 is made of PCL polycaprolactone.

[0034] Among them, the Rayon fiber absorbent cotton 105 has good breathability and water absorption properties, which can quickly absorb moisture while allowing air to circulate, reducing the accumulation of moisture on the skin surface, thereby improving the comfort of use. The PCL polycaprolactone drug release layer 106 can achieve long-term drug release, thereby prolonging the time of drug action in the body, thereby reducing the frequency of administration and improving treatment compliance and effectiveness.

[0035] Furthermore, the stretching assembly 200 includes adhesive strips 201 fixedly connected to both sides of the antibacterial layer 102, a soft-textured surface 202 fixedly connected to the top of the adhesive strips 201, and a bristle surface 203 fixedly connected to both sides of the top of the protective layer 101 and used in conjunction with the soft-textured surface 202.

[0036] Specifically, the stretching assembly 200 also includes a second adhesive layer 204 fixedly connected to the bottom of the adhesive strip 201, and a V-shaped groove 205 opened on the outside of the protective layer 101, the V-shaped groove 205 extending to the outside of the first adhesive layer 104.

[0037] It should be explained that the adhesive strip 201 is made of TPE thermoplastic elastic material that can be stretched over a wide range and is not easy to break, in order to adapt to the application scenarios that require high elasticity. When the soft surface 202 and the bristle surface 203 are attached, the small hooks on the bristle surface 203 will embed into the fibers of the soft surface 202 to form a mechanical lock, thereby preventing the second adhesive layer 204 from sticking to the skin surface when not in use. The V-shaped groove 205 can reduce the stress concentration of the adhesive when stretched or bent, so that the adhesive strip can distribute stress more evenly when under force, thereby improving its extensibility.

[0038] During use, pulling the adhesive strip 201 expands the adhesive patch to a suitable size. The V-shaped groove 205 reduces stress concentration when the patch is stretched or bent, allowing the adhesive strip to distribute stress more evenly under force, thus improving its extensibility. After the patch expands to a suitable size, the first adhesive layer 104 and the second adhesive layer 204 are bonded to the skin surface. The protective layer 101 prevents bacteria, viruses, and other microorganisms from invading the wound, reducing the risk of infection. The antibacterial layer 102 penetrates the cell membrane of microorganisms and interferes with cell metabolism, leading to the death of microorganisms. The water-repellent layer 103 blocks the penetration of liquid water while allowing water vapor molecules to pass through. The absorbent cotton 105 quickly absorbs any water molecules that accidentally penetrate the water-repellent layer 103 and allows air circulation to reduce moisture accumulation on the skin surface. The drug release layer 106 enables long-term drug release, thereby prolonging the drug's action time in the body, reducing the frequency of administration, and improving treatment compliance and effectiveness.

[0039] In applications where stretching the adhesive patch is not required, the soft bristle side 202 and the bristle side 203 are bonded together to form a mechanical lock, thereby preventing the second adhesive layer 204 from adhering to the skin surface when not in use, which would reduce the breathability of the adhesive patch. Reducing the bonding area can further improve patient comfort.

[0040] In summary, the PET polyester protective layer 101 and the polyester fiber silver ion carrier antibacterial layer 102 work together to prevent bacterial invasion and reduce the risk of infection; the ePTFE expanded polytetrafluoroethylene water-repellent layer 103 can block liquid water penetration while maintaining breathability; the PSA pressure-sensitive adhesive first adhesive layer 104 provides fast and efficient adhesion to improve the safety of the adhesive; the cooperation of the various components in the stretching assembly 200 ensures that the adhesive maintains stable adhesion when stretched, and the V-groove 205 reduces stress concentration to improve the extensibility and user comfort of the adhesive.
