Description

Technical Field

[0001] This invention relates to the field of medical supplies technology, and in particular to a functional plaster base fabric. Background Technology

[0002] Functional plasters typically consist of medication, a base, and excipients. They exert their therapeutic effects through skin absorption or stimulation, and can be used to relieve symptoms of various conditions such as muscle strain, arthritis, neuralgia, and skin infections. The drug components are selected based on therapeutic needs, such as analgesics, anti-inflammatory agents, and blood-activating and stasis-removing agents. The base, typically made of non-woven fabric, petrolatum, or rubber, is used to carry and fix the medication. Excipients are used to adjust the plaster's consistency, viscosity, and other properties. The mechanisms of action of functional plasters mainly include drug penetration and absorption, local stimulation, and thermal effects. The medication penetrates the skin to exert its therapeutic effect; local stimulation promotes blood circulation and relieves pain; and the thermal effect relaxes muscles and increases local blood flow. Electromagnetic fields can promote ulcer healing because they stimulate intracellular metabolic processes, promoting cell repair and regeneration, altering neuronal excitability, and reducing inflammatory responses, thereby relieving pain and inflammation-related symptoms. They also promote blood circulation, increasing local blood flow and oxygen supply, providing necessary nutrients and oxygen for ulcer repair. However, traditional electromagnetic field therapy requires complex, bulky, and expensive equipment, necessitates external power supply, requires professional operation, and cannot provide real-time treatment. To address these issues, a functional plaster base fabric was designed. When continuously rubbed, patted, or pressed, the polymer membrane generates Maxwell's pulse electric field and pulsed current under the influence of force. This activates cells, promotes blood circulation, raises the temperature of local tissues, accelerates cell metabolism, and produces a synergistic effect when used in conjunction with the plaster, enhancing drug absorption and improving the plaster's efficacy. 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 functional plaster base fabric that, under continuous friction, patting, or pressing, generates a Maxwell pulsed electric field and pulsed current to activate cells, promote blood circulation, raise local tissue temperature, accelerate cell metabolism, and thus enhance drug absorption and improve the efficacy of the plaster. The functional plaster base fabric, subjected to continuous force, generates a Maxwell pulsed electric field and pulsed current, which are targeted, helping the drug to precisely act on the target area and regulate drug release for the treatment of tumors and cytotoxic tumors.

[0004] To achieve the above objectives, the present invention provides the following technical solution: the functional plaster base cloth is composed of one or more polymer films selected from polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), and perfluoroethylene propylene copolymer (FEP), or a composite film formed by them and one or more other materials. When the functional plaster base cloth is continuously rubbed, patted, or pressed, the polymer film is subjected to continuous force to generate a Maxwell pulse electric field and pulse field current, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the effect of the plaster.

[0005] The functional plaster base fabric is subjected to continuous force to generate Maxwell pulse electric field and pulse field current, which are targeted and help the drug act precisely on the target area, regulate drug release, and are used to treat tumors and cytomas.

[0006] Other materials in the composite membrane include one or more of nonwoven fabric, silicone rubber, polyester, polyethylene, polypropylene, polyethylene terephthalate, and polyimide. The addition of these materials not only enhances the mechanical properties and durability of the base fabric but also improves its breathability and comfort, thereby further enhancing the therapeutic effect.

[0007] The functional plaster base fabric can be composed of a polymer film and a non-woven fabric. When the functional plaster base fabric is subjected to continuous external force, the polymer film and the non-woven fabric continuously interact, generating a Maxwell pulse electric field and a pulse current. This structure is both simple and effective, fully utilizing the electrical properties of the polymer film and the breathability of the non-woven fabric.

[0008] The functional plaster base fabric has a multi-layer structure, consisting of two layers of non-woven fabric sandwiching one or more layers of polymer film. This multi-layer structure can further enhance the electrical properties and durability of the base fabric, while maintaining its excellent mechanical strength and breathability.

[0009] The manufacturing method of the functional plaster base fabric includes compounding a polymer film with other materials through processes such as hot pressing, bonding, and coating. These processes ensure a good interfacial bond between the polymer film and other materials, thereby producing a functional plaster base fabric with excellent performance.

[0010] To further improve the electrical properties and biocompatibility of the functional plaster base fabric, this invention can use nanotechnology to modify the polymer membrane.

[0011] In order to prolong the drug release time and improve drug utilization, the present invention can design a drug sustained-release layer in the functional plaster base fabric.

[0012] The beneficial technical effects of this invention are as follows: Compared with existing technologies, the functional plaster base fabric of this invention does not require an external power source. Under continuous friction, patting, or pressing, it can generate Maxwell's pulsed electric field and pulsed current to activate cells, promote blood circulation, raise local tissue temperature, and accelerate cell metabolism. When used in conjunction with the plaster, it produces a synergistic effect, enhancing drug absorption and improving the plaster's efficacy. The technical solution requires no external instruments or equipment, is simple to operate, highly safe, and has a simple preparation process. The functional plaster base fabric provided by this invention not only improves the therapeutic effect of plasters but also provides a new solution for targeted drug therapy and the treatment of specific diseases.

Detailed Implementation

[0029] 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.

[0030] 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.

[0031] This invention provides a functional plaster base fabric, which is composed of one or more polymer films selected from polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), and perfluoroethylene propylene copolymer (FEP), or a composite film formed by these and one or more other materials. When the functional plaster base fabric is continuously rubbed, patted, or pressed, the polymer film generates a Maxwell pulse electric field and pulsed current under the action of force. This can activate cells, promote blood circulation, raise the temperature of local tissues, and accelerate cell metabolism. When used in combination with the plaster, the functional plaster base fabric produces a synergistic effect, enhancing drug absorption and improving the efficacy of the plaster. The Maxwell pulse electric field and pulsed current generated by the continuous force acting on the functional plaster base fabric have targeting properties, which helps the drug to act precisely on the target area and regulate drug release, making it suitable for the treatment of tumors and cytotoxic tumors.

[0032] Figure 1-11 These are schematic diagrams of a functional plaster base fabric. Figure 15 This is a photograph of a functional plaster base fabric. The functional plaster base fabric is composed of one or more polymer films selected from polytetrafluoroethylene (PTFE), polyvinylidene fluoride (PVDF), and perfluoroethylene propylene copolymer (FEP). The polymer film is composited with one or more other materials such as nonwoven fabric, silicone rubber, polyester, polyethylene, polypropylene, polyethylene terephthalate, and polyimide through processes such as hot pressing, bonding, and coating. When the functional plaster base fabric is continuously rubbed, patted, or pressed, the polymer film generates a Maxwell pulse electric field and pulsed current under the action of force. This can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, and produce a synergistic effect when used in conjunction with the plaster, enhancing drug absorption and improving the efficacy of the plaster. Figure 12 This diagram illustrates the principle of how a functional plaster base fabric generates a Maxwell pulse electric field under continuous force. Any contact, friction, or collision between substances will generate a Maxwell displacement electric field and a Maxwell displacement current. This is a completely new discovery. The functional plaster base fabric 12 can be applied to the surface of the skin 13. When a person's hand 11 continuously presses or rubs the functional plaster base fabric on the skin, the polymer membrane is subjected to continuous force, or there is continuous interaction between the polymer membrane and the non-woven fabric, generating a Maxwell pulse electric field and a pulse current. This can be vertical, horizontal, or inclined, and the force includes, but is not limited to, friction, contact, vibration, collision, or patting. Since the human body is conductive, the Maxwell pulse electric field and pulse current generated by the functional plaster base fabric can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, and produce a synergistic effect when used in conjunction with the plaster, enhancing drug absorption and improving the plaster's efficacy. Figure 13 As shown, a functional plaster base fabric can generate a 60 microamp pulsed current under continuous friction. Through continuous friction or pressing of the functional plaster base fabric, the generated Maxwell pulsed electric field can stimulate and activate cells, causing them to migrate in a directed manner. Figure 14 (This is an experimental photograph illustrating electromigration of cells under the influence of an electric field.) Furthermore, pulsed electric fields can guide charged particles (such as ions or charged groups in drug molecules). The charged portion of the drug molecule is guided by the electric field, thus moving directionally towards the target region. Pulsed current can also stimulate surrounding tissues, promoting drug absorption and penetration, making it easier for the drug to reach the target area and reducing damage to surrounding normal tissues. By regulating drug release, continuous and stable treatment of tumors or cytomas can be achieved, improving treatment efficacy.

[0033] The following description, in conjunction with specific embodiments, illustrates this point.

[0034] Example 1

[0035] like Figure 1 As shown, in this embodiment, a functional plaster base fabric includes polytetrafluoroethylene (PTFE) 1, preferably a polytetrafluoroethylene (PTFE) polymer membrane with a microporous structure. This membrane can convert mechanical energy into electrical energy under continuous external force (such as continuous friction, patting, or pressing by a human hand), generating a Maxwell pulse electric field that promotes cell regeneration and tissue repair. This generates a Maxwell pulse electric field and pulse field current, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the effect of the plaster.

[0036] Example 2

[0037] like Figure 2 As shown, in this embodiment, a functional plaster base fabric comprises polytetrafluoroethylene (PTFE) 1, polyvinylidene fluoride (PVDF) 2, and a PTFE polymer film and a PVDF polymer film bonded together using an adhesive process to ensure structural stability and fully utilize the properties of both materials. The functional plaster base fabric can be further integrated with the plaster. When a continuous external force is applied to the functional plaster base fabric, it generates a Maxwell pulse electric field. This electric field can penetrate the skin, activate cells, promote blood circulation, raise the temperature of local tissues, and accelerate cell metabolism, thereby significantly enhancing the absorption efficiency of the active ingredients in the plaster and improving the therapeutic effect.

[0038] Example 3

[0039] like Figure 3 As shown, a functional plaster base fabric in this embodiment includes polytetrafluoroethylene (PTFE) 1, polyvinylidene fluoride (PVDF) 2, and perfluoroethylene propylene copolymer (FEP) 3. A coating process is used to coat PTFE, PVDF, and FEP sequentially or simultaneously onto the surface of a substrate. By precisely controlling the coating thickness and curing conditions, the three layers are ensured to bond tightly, forming a functional plaster base fabric with excellent mechanical and electrical properties. The PTFE layer provides the main structural support and chemical stability of the base fabric, the PVDF layer exhibits piezoelectric effect, and the FEP layer enhances its electrostatic properties. When continuous external force is applied to the functional plaster base fabric, it can generate a Maxwell pulse electric field, which can penetrate the skin, activate cells, promote blood circulation, raise the temperature of local tissues, and accelerate cell metabolism, thereby significantly enhancing the absorption efficiency of the active ingredients in the plaster and improving the therapeutic effect.

[0040] Example 4

[0041] like Figure 4As shown, a functional plaster base fabric in this embodiment includes polytetrafluoroethylene (PTFE) 1 and nonwoven fabric 4. During the manufacturing process, PTFE is first uniformly coated or bonded to the surface of the nonwoven fabric using processes such as hot pressing, bonding, or coating. By precisely controlling process parameters, such as temperature, pressure, and time, a tight bond between PTFE and the nonwoven fabric is ensured, forming a functional plaster base fabric with excellent mechanical and electrical properties. The functional base fabric can be further combined with a plaster to form the final functional plaster patch. When a continuous external force is applied to the functional plaster base fabric, it generates a Maxwell pulse electric field, which is targeted and can precisely act on the target area, activating cells, promoting blood circulation, raising the temperature of local tissues, and accelerating cell metabolism, thereby significantly enhancing the absorption efficiency of the active ingredients in the plaster and improving the therapeutic effect. Importantly, the targeting capability of this functional plaster base fabric also helps to regulate drug release, allowing it to act more precisely on target areas such as tumors and cytokines.

[0042] Example 5

Using advanced processes such as hot pressing, bonding, or coating, a PVDF film is uniformly coated or bonded to the surface of the silicone rubber substrate. By precisely controlling the hot pressing temperature, pressure, and time, as well as the type and amount of adhesive, a strong and uniform composite structure is ensured between PVDF and silicone rubber. This composite structure not only inherits the piezoelectric effect of PVDF but also the excellent elasticity and biocompatibility of silicone rubber. When continuous external force is applied to the functional plaster base fabric, it can generate a Maxwell pulse electric field, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the effect of the plaster.

[0045] like Figure 6As shown, a functional plaster base fabric in this embodiment includes polytetrafluoroethylene (PTFE) 1, perfluoroethylene propylene copolymer (FEP) 3, nonwoven fabric 4, and PTFE. First, a hot-pressing process is used to initially composite the PTFE film and FEP film onto the nonwoven fabric 4. By precisely controlling the hot-pressing temperature, pressure, and time, a good interfacial bond is ensured between the two fluoropolymer films and the nonwoven fabric. Subsequently, the composite structure is further processed using bonding or coating processes to enhance its overall strength and durability, while ensuring the uniformity and continuity of the fluoropolymer layers. When continuous external force is applied to the functional plaster base fabric, it generates a Maxwell pulse electric field, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the effect of the plaster.

[0046] Example 7

[0047] like Figure 7 As shown, a functional plaster base fabric in this embodiment comprises polytetrafluoroethylene (PTFE) 1, polyester 6, and polyethylene 7. First, a hot-pressing process is used to initially composite the PTFE film with the polyester substrate. By precisely controlling the hot-pressing temperature, pressure, and time, a good interfacial bond is ensured between the PTFE layer and the polyester layer, while maintaining the electrical properties of the PTFE layer. Subsequently, using an adhesive or coating process, the composite layer is uniformly coated or adhered to the surface of the polyethylene, further enhancing the weather resistance, chemical stability, and electrical properties of the base fabric. When continuous external force is applied to the functional plaster base fabric, it can generate a Maxwell pulse electric field, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the effect of the plaster.

[0048] Example 8

[0049] like Figure 8 As shown, in this embodiment, a functional plaster base fabric comprises polytetrafluoroethylene (PTFE) 1, perfluoroethylene propylene copolymer (FEP) 3, polypropylene 8, and polyethylene terephthalate 9. PTFE, FEP, polypropylene, and polyethylene terephthalate are composited through processes such as hot pressing, bonding, and coating, and then combined with the plaster to form the functional plaster base fabric. When continuous external force is applied to the functional plaster base fabric, it generates a Maxwell pulse electric field, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the efficacy of the plaster.

[0050] Example 9

[0051] like Figure 9As shown, in this embodiment, a functional plaster base fabric comprises polytetrafluoroethylene (PTFE) 1, polypropylene 8, and polyimide 10. PTFE, polypropylene, and polyimide are composited through processes such as hot pressing, bonding, and coating, and then treated to combine with the plaster to form the functional plaster base fabric, which can be further bonded to the plaster. When continuous external force is applied to the functional plaster base fabric, it can generate a Maxwell pulse electric field, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the effect of the plaster.

[0052] Example 10

[0053] like Figure 10 As shown, in this embodiment, a functional plaster base fabric includes polytetrafluoroethylene (PTFE) 1 and non-woven fabric 4. PTFE is laminated between two layers of non-woven fabric through processes such as hot pressing, bonding, and coating to form a multi-layered functional plaster base fabric, which can be further bonded to the plaster. When continuous external force is applied to the functional plaster base fabric, it generates a Maxwell pulse electric field, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, thereby enhancing drug absorption and improving the effect of the plaster.

[0054] Example 11

[0055] like Figure 11 As shown, a functional plaster base fabric in this embodiment includes polytetrafluoroethylene (PTFE) 1, perfluoroethylene propylene copolymer (FEP) 3, and nonwoven fabric 4. First, a hot-pressing process is used to initially composite the PTFE film with a layer of nonwoven fabric. By precisely controlling the hot-pressing temperature, pressure, and time, a good interfacial bond is ensured between the PTFE layer and the nonwoven fabric layer, while maintaining the electrical properties and mechanical strength of the PTFE layer. Subsequently, an FEP layer is uniformly coated or bonded onto the PTFE / nonwoven fabric composite structure using an adhesive or coating process. Next, another layer of nonwoven fabric is bonded to the FEP layer through a hot-pressing or adhesive process, forming a multi-layered functional plaster base fabric that can be further integrated with the plaster. This multi-layered structure not only possesses the excellent electrical properties and chemical stability of PTFE and FEP, but the addition of nonwoven fabric also improves the breathability and comfort of the base fabric. When a continuous external force is applied to the functional plaster base fabric, the base fabric generates a Maxwell pulsed electric field, which can activate cells, promote blood circulation, raise the temperature of local tissues, accelerate cell metabolism, and thus enhance drug absorption and improve the efficacy of the plaster. Simultaneously, the generated Maxwell pulsed electric field and pulsed current also have targeting properties, helping the drug to precisely act on the target area and regulate drug release, making it suitable for treating tumors and cytokines.
