Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, and in particular to a self-generating adhesive bandage. Background Technology

[0002] Band-aids are one of the most commonly used surgical medications in daily life. They are applied to wounds to prevent bacteria, dust, and other contaminants from contacting the wound, thus reducing the risk of infection. For minor bleeding wounds, band-aids can help stop bleeding through their adhesive properties and pressure. They also provide pressure to the wound, helping to reduce pain and discomfort. A band-aid typically consists of a long strip of adhesive tape with a small piece of medicated gauze attached in the middle. Due to its structural limitations, band-aids are generally only used for emergency treatment of small wounds, providing temporary hemostasis and wound protection. Electromagnetic field energy can promote cell repair and regeneration. Its main mechanisms include: promoting cell metabolism, promoting vasodilation to increase local blood flow and oxygen supply, thereby accelerating tissue repair, regulating the number and activity of immune cells, and affecting the concentration and distribution of intracellular calcium ions. Low-frequency electromagnetic fields are mainly used to promote fracture healing and soft tissue injury repair, high-frequency electromagnetic fields are mainly used to promote nerve regeneration and reduce inflammation, and pulsed electromagnetic fields are mainly used to promote fracture healing and nerve injury repair. Electromagnetic field repair technology has advantages over other repair methods, including non-invasiveness, safety, high efficiency, and wide applicability. However, traditional electromagnetic field repair equipment is complex, bulky, expensive, requires external power supply, and necessitates operation by professional personnel, making real-time treatment impossible. To address these issues, a self-generating adhesive bandage has been designed that can generate Maxwell pulse electric and current fields under external force for real-time treatment. Summary of the Invention

[0003] The technical problem this invention aims to solve is to address the shortcomings of the existing technology by providing a self-generating adhesive bandage. Under continuous external force, this bandage generates a Maxwell pulse electric field, accelerating cell regeneration and tissue repair, thereby promoting wound healing. Therefore, this bandage not only possesses the basic functions of a traditional bandage, such as wound protection and infection prevention, but also generates a Maxwell pulse electric field and a Maxwell pulse current under continuous external force. This characteristic enables it to significantly accelerate cell regeneration and tissue repair processes, effectively promoting wound healing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: the self-generating adhesive bandage consists of a power-generating layer and a regular adhesive bandage, wherein the regular adhesive bandage consists of an adhesive layer, an absorbent pad, and a release liner or a barrier membrane. When the self-generating adhesive bandage is continuously rubbed and pressed, the power-generating layer is subjected to continuous force to generate a Maxwell pulse electric field and a pulsed current, which can accelerate cell regeneration and tissue repair, thereby promoting wound healing.

[0005] The power generation layer can be independently disposed between the adhesive layer, the absorbent pad, and the isolation membrane or release paper, or it can be integrated with one or more of the three.

[0006] The power generation layer is composed of one or more films selected from polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), and perfluoroethylene propylene copolymer (FEP), or a composite film composed of them and other materials.

[0007] The power generation layer can be used as an adhesive layer or combined with an adhesive layer. The adhesive layer is made of a flexible material, including one or more of the following: medical tape, medical-grade nonwoven fabric, PTFE membrane, PVDF membrane, FEP membrane, polyester fiber cloth, nylon fiber cloth, polyurethane foam, or silicone.

[0008] The power generation layer can be combined with an absorbent pad, which is made of a high-molecular absorbent material or a composite absorbent material containing PTFE, PVDF, or FEP. The absorbent material includes one or more of sodium polyacrylate, polyvinyl alcohol, or sodium alginate.

[0009] The power generation layer can be combined with an isolation permeation membrane or release paper. The isolation permeation membrane or release paper is made of a breathable and waterproof material or a composite material containing PTFE, PVDF, or FEP, including one or more of PTFE microporous membrane, polyurethane (PU) waterproof and breathable membrane or polyethylene (PE) waterproof and breathable membrane.

[0010] The self-generating adhesive bandage can be a multi-layered or staggered structure. The power-generating layer can be sandwiched between different structural layers of a commonly used adhesive bandage, and the layers are fixed together by adhesive or heat pressing.

[0011] The beneficial technical effects of the present invention: The self-powered adhesive bandage of the present invention does not require an external power source. It can stably and efficiently generate Maxwell pulse electric field and pulse field current under the action of external force, thereby accelerating cell regeneration and tissue repair, thus achieving the effect of promoting wound healing and bringing patients a faster recovery experience.

[0012] Compared to existing technologies, the self-generating adhesive bandage provided by this invention requires no external power source. It generates a Maxwell pulse electric field and pulsed current through simple external force, thereby accelerating cell regeneration and tissue repair, and promoting wound healing. This not only reduces usage costs but also significantly improves the product's portability and ease of use. Furthermore, the manufacturing process of this invention is relatively simple, facilitating large-scale production and widespread adoption, providing patients with a more economical treatment option. In addition, since no external power source is required, safety hazards caused by power failure or improper operation are avoided, providing patients with a safer and more reliable treatment guarantee.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0028] Conversely, this invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of the invention as defined in the claims. Furthermore, to provide a better understanding of the invention, certain specific details are described in detail below. However, those skilled in the art will fully understand the invention even without these detailed descriptions.

[0029] This invention provides a self-generating adhesive bandage, comprising a power-generating layer and a conventional adhesive bandage. The conventional adhesive bandage consists of an adhesive layer, an absorbent pad, and a release liner or insulating membrane. The power-generating layer is made of membrane materials such as polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), and perfluoroethylene propylene copolymer (FEP), or is composited with other materials. The power-generating layer can be independently disposed between the adhesive layer, absorbent pad, and release liner or insulating membrane, or it can be integrated with one or more of these three components. When the self-generating adhesive bandage is continuously rubbed and pressed, the power-generating layer is subjected to continuous force, generating a Maxwell pulse electric field and a pulsed current, which can accelerate cell regeneration and tissue repair, thereby promoting wound healing.

[0030] Figure 1-8 These are schematic diagrams of a self-generating adhesive bandage. Figure 10 and Figure 11This is a physical image of a self-generating adhesive bandage. The self-generating adhesive bandage consists of a generating layer and a regular adhesive bandage. The regular adhesive bandage comprises an adhesive layer, an absorbent pad, and a release liner or insulating membrane. The generating layer can be independently positioned between the adhesive layer, absorbent pad, and release liner, or it can be integrated with one or more of these three components. When the self-generating adhesive bandage is continuously rubbed and pressed, the generating layer is subjected to continuous force, generating a Maxwell pulse electric field and pulse current, which can accelerate cell regeneration and tissue repair, thereby promoting wound healing. The self-generating layer is made of one or more of polyvinylidene fluoride (PVDF), polytetrafluoroethylene (PTFE), and perfluoroethylene propylene copolymer (FEP). The regular adhesive bandage comprises an adhesive layer, absorbent pad, and release liner, and the generating layer can be independently positioned between the adhesive layer, absorbent pad, and release liner, or it can be integrated with one or more of these three components, or it can be composed of a composite film of these components and other materials. Figure 9 This is a schematic diagram illustrating the principle of a self-generating adhesive bandage that uses a Maxwell's electric field to accelerate cell regeneration and tissue repair. Any contact, friction, or collision between substances will generate a Maxwell's displacement electric field and a Maxwell's displacement field current. This is a completely new discovery, a leap from zero to one. The self-generating adhesive bandage 13 can be applied to the surface of the skin 14. During the process of pressing or rubbing the self-generating adhesive bandage with a hand 12, the generating layer is subjected to continuous force or interacts continuously with a regular adhesive bandage. This force can be vertical, horizontal, or inclined, including but not limited to friction, contact, vibration, collision, or patting. The human body is conductive; the Maxwell's pulsed electric field and pulsed field current generated by the self-generating adhesive bandage can accelerate cell regeneration and tissue repair, thereby promoting wound healing. Through continuous friction or pressing of the self-generating adhesive bandage, the generated Maxwell's pulsed electric field can stimulate and activate cells, causing them to migrate in a directed manner. Figure 13 (Experimental photograph showing cell electromigration under the influence of an electric field)

[0031] The following description, in conjunction with specific embodiments, illustrates this point.

[0032] Example 1

[0033] like Figure 1As shown, a self-generating adhesive bandage in this embodiment includes a power-generating layer 1 and a conventional adhesive bandage layer 2. The power-generating layer is preferably a polyvinylidene fluoride (PVDF) membrane with a microporous structure. This membrane not only converts mechanical energy into electrical energy under external force (such as friction or pressure during human activity), generating Maxwell's pulse electric field and pulsed field current that promote cell regeneration and tissue repair, but also ensures good breathability due to its microporous design, helping to keep the wound dry and reducing the risk of infection. The conventional adhesive bandage layer consists of an adhesive tape layer, preferably medical tape. The bottom layer is a fiber substrate providing strength, the middle layer is medical-grade polypropylene pressure-sensitive adhesive ensuring a firm adhesion between the bandage and the skin with low allergenicity, and the surface layer is a protective film that is easy to remove before use. The power-generating layer is fixed to the surface of the conventional adhesive bandage layer by using polypropylene pressure-sensitive adhesive to form a self-generating adhesive bandage, ensuring a strong bond between the two while maintaining overall thinness, portability, and breathability. When the self-generating adhesive bandage is continuously rubbed and pressed, the power generation layer is subjected to continuous force to generate Maxwell pulse electric field and pulse field current, which can accelerate cell regeneration and tissue repair, thereby promoting wound healing.

[0034] Example 2

[0035] like Figure 2As shown, a self-generating adhesive bandage in this embodiment includes a power-generating layer of polytetrafluoroethylene (PTFE) 6, a conventional adhesive bandage layer 3, a conventional absorbent pad 4, and an insulating membrane or release paper 5. The PTFE can be configured with a breathable structure or pores to ensure good breathability, helping to keep the wound dry and reduce the risk of infection. Under external force (such as friction or pressure during human activity), the membrane converts mechanical energy into electrical energy, generating Maxwell's pulse electric field and pulsed field current that promote cell regeneration and tissue repair. The adhesive bandage layer is made of a soft and elastic material, including one or more of medical-grade nonwoven fabric, polyester fiber cloth, nylon fiber cloth, polyurethane foam, or silicone. It is coated with medical-grade polypropylene pressure-sensitive adhesive to ensure a firm fit between the bandage and the skin and low allergenicity. The surface is a protective film that is easy to remove before use. The absorbent pad is made of a superabsorbent polymer material, including one or more of sodium polyacrylate, polyvinyl alcohol, or sodium alginate. The release membrane or paper is made of breathable and waterproof materials, including one or more of polytetrafluoroethylene (PTFE) microporous membranes, polyurethane (PU) waterproof and breathable membranes, or polyethylene (PE) waterproof and breathable membranes. PTFE is bonded to the adhesive layer surface using polypropylene pressure-sensitive adhesive to form a self-generating adhesive bandage, ensuring a strong bond while maintaining overall thinness, portability, and breathability. Different bandage layers can be constructed into multi-layered or staggered structures to form a composite multi-layered self-generating adhesive bandage. When the self-generating adhesive bandage is continuously rubbed and pressed, the generating layer is subjected to continuous force, generating Maxwell's pulse electric field and pulsed current, which can accelerate cell regeneration and tissue repair, thereby promoting wound healing. Figure 10 This is a picture of a self-generating adhesive bandage.

The power-generating layer is preferably made of polyvinylidene fluoride (PVDF) 7. PVDF can be configured with a breathable structure or pores to ensure good breathability, helping to keep the wound dry and reduce the risk of infection. Under external force (such as friction or pressure during human activity), this membrane converts mechanical energy into electrical energy, generating a Maxwell pulse electric field that promotes cell regeneration and tissue repair. The adhesive layer is made of a soft and elastic material, coated with medical-grade polypropylene pressure-sensitive adhesive to ensure a firm fit between the bandage and the skin with low allergenicity. The surface is a protective film that is easy to remove before use. The absorbent pad is made of a superabsorbent polymer, and the release liner or insulating membrane is made of a breathable and waterproof material. Polyvinylidene fluoride (PVDF) is bonded to the surface of an absorbent pad using polypropylene pressure-sensitive adhesive to form a self-generating adhesive bandage. This self-generating bandage can be combined with other bandage layers to create a multi-layered or interlaced structure, forming a composite multi-layered self-generating adhesive bandage. When the self-generating bandage is continuously rubbed and pressed, the generating layer experiences continuous force, producing Maxwell's pulse electric field and pulsed current, which can accelerate cell regeneration and tissue repair, thereby promoting wound healing.

[0039] like Figure 4As shown, a self-generating adhesive bandage in this embodiment includes a power-generating layer and a conventional adhesive bandage. The power-generating layer is preferably made of polyvinylidene fluoride (PVDF) 7 or fluorinated ethylene propylene copolymer (FEP) 8, both of which can be configured with a breathable structure or pores to ensure good breathability, helping to keep the wound dry and reduce the risk of infection. Under external force (such as friction or pressure during human activity), this membrane converts mechanical energy into electrical energy, generating a Maxwell pulse electric field that promotes cell regeneration and tissue repair. The self-generating layers are fixed together by adhesive bonding or hot pressing to construct a composite multilayer self-generating layer. The conventional adhesive bandage isolation membrane or release paper 5 is made of breathable and waterproof materials. The composite multilayer self-generating layer is fixed to the surface of the isolation membrane or release paper by adhesive bonding or hot pressing to form the self-generating adhesive bandage. The adhesive layer 3 is made of a soft and elastic material, with a medical-grade polypropylene pressure-sensitive adhesive layer to ensure a firm fit between the bandage and the skin and low allergenicity. The surface layer is a protective film that is easy to remove before use. The absorbent pad 4 is made of a super absorbent polymer material. The adhesive layer is fixed to the absorbent pad using polypropylene pressure-sensitive adhesive, forming a composite multi-layered bandage. The self-generating bandage can be combined with other different bandage layers to form a multi-layered or interlaced structure, creating a composite multi-layered self-generating bandage. When the self-generating bandage is continuously rubbed and pressed, the generating layer is subjected to continuous force, generating a Maxwell pulse electric field and pulsed current, which can accelerate cell regeneration and tissue repair, thereby promoting wound healing.

Under external force (such as friction or pressure during human activity), the two membranes convert mechanical energy into electrical energy, generating Maxwell's pulse electric field and pulsed field current that promote cell regeneration and tissue repair. The self-generating layers are fixed together by adhesive bonding or hot pressing to construct a composite multilayer self-generating layer. The adhesive layer is made of a soft and elastic material, with a medical-grade polypropylene pressure-sensitive adhesive applied to ensure a firm fit between the bandage and the skin and low allergenicity. The surface layer is a protective film that is easy to remove before use. The composite multilayer self-generating layer is fixed to the surface of the adhesive layer using polypropylene pressure-sensitive adhesive to form a self-generating adhesive bandage. The absorbent pad is made of a super absorbent polymer material, while the insulating membrane or release paper is made of a breathable and waterproof material. The absorbent pad is fixed to the insulating membrane or release paper by adhesive bonding or heat pressing to form a composite multilayer adhesive bandage.
