Description

Technical Field

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

[0002] Ulcer patches are common treatments for localized defects or ulcers in the skin or mucous membranes. They effectively relieve pain and discomfort associated with oral ulcers and promote healing. Ulcer patches are primarily used to relieve and treat symptoms such as oral ulcers, canker sores, swollen and painful gums, and oral inflammation. They are suitable for people of all ages, including adults, children, and the elderly. Traditional ulcer patches are medicated, using added medications to relieve pain and promote wound healing. Electromagnetic fields can also 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, requires external power, necessitates professional operation, and cannot provide real-time treatment. To address these issues, a portable, self-generating ulcer patch has been designed. This patch can generate a Maxwell pulse electric field through external force for real-time ulcer treatment. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a self-generating ulcer patch that can generate a Maxwell pulse electric field under the continuous action of external force, thereby accelerating cell regeneration and tissue repair and promoting ulcer healing.

[0004] To achieve the above objectives, the present invention provides the following technical solution: the self-generating ulcer patch comprises a self-generating layer and a commonly used ulcer patch, wherein the commonly used ulcer patch comprises a drug-containing layer and a protective layer, the drug-containing layer contains medicinal ingredients, the protective layer is selected from one or more of polyacrylic acid resin, diethyl phthalate, or hydroxypropyl methylcellulose, the self-generating layer is composed of one or more membranes selected from polylactic acid, polarized cellulose dressing, and polyvinyl alcohol, or is composed of a composite membrane of these and other strongly electronegative biocompatible materials, the self-generating layer can serve as a protective layer or be combined with a protective layer, and the self-generating layer can be independent. The self-generating ulcer patch is positioned between the drug-containing layer and the protective layer, or it can be integrated with one or more layers of either layer. The self-generating layer can be a multi-layered or interlaced structure. The self-generating layer can be sandwiched between different component layers of a commonly used ulcer patch. The layers are connected or combined by coating, mixing, or pressing. When the self-generating ulcer patch is continuously rubbed and pressed, the generating layer is subjected to continuous force to generate a Maxwell pulse electric field and a pulse field current, which can activate cells, promote blood circulation, and work synergistically with ulcer medication to accelerate cell regeneration and tissue repair, thereby promoting the healing of ulcer wounds.

[0005] The beneficial technical effects of this invention are as follows: Compared with existing technologies, the self-generating ulcer patch of this invention does not require an external power source. It can generate a Maxwell pulse electric field through simple external force, thereby accelerating cell regeneration and tissue repair, and thus promoting ulcer healing. The self-generating ulcer patch of this invention has the advantages of simple operation, high safety, and simple preparation process. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] 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.

[0024] This invention provides a self-generating ulcer patch, which consists of a self-generating layer (1) and a commonly used ulcer patch (2). The commonly used ulcer patch consists of a drug-containing layer (3) and a protective layer (4). The self-generating layer (1) can be independently disposed between the drug-containing layer (3) and the protective layer (4), or it can be integrated with one or more of the two layers. The self-generating layer is composed of one or more films of polylactic acid, polarized cellulose dressing, and polyvinyl alcohol, or a composite film of them and other strongly electronegative biocompatible materials. When the self-generating ulcer patch is continuously rubbed and pressed, the self-generating layer is subjected to continuous force to generate Maxwell pulse electric field and pulse field current, which can activate cells, promote blood circulation, and work synergistically with ulcer drugs to accelerate cell regeneration and tissue repair, thereby achieving the effect of promoting ulcer wound healing.

[0025] Figure 1-10 These are schematic diagrams of a self-generating ulcer dressing. The self-generating ulcer dressing consists of a self-generating layer and a regular ulcer dressing. When the self-generating ulcer dressing is continuously rubbed and pressed, the self-generating layer is subjected to continuous force to generate a Maxwell pulse electric field and a pulse field current, which can activate cells, promote blood circulation, and work synergistically with ulcer medication to accelerate cell regeneration and tissue repair, thereby achieving the effect of promoting ulcer wound healing. The self-generating layer is composed of one or more membranes selected from polylactic acid, polarized cellulose dressing, and polyvinyl alcohol, or is composed of a composite membrane of these and other strongly electronegative biocompatible materials. The regular ulcer dressing consists of a drug-containing layer (3) and a protective layer (4). The self-generating layer (1) can be independently set between the drug-containing layer (3) and the protective layer (4), or it can be fused with one or more of the two layers. Figure 11 This diagram illustrates the principle behind a self-generating ulcer patch that uses a Maxwell's electric field to heal wounds. Any contact, friction, or collision between substances generates a Maxwell's displacement electric field, resulting in a Maxwell's displacement current. This is a groundbreaking discovery. The self-generating ulcer patch 13 is applied to the skin 14. When a person presses or rubs the patch, the self-generating layer experiences a continuous force, or interacts with a regular ulcer patch. 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 displacement electric field generated by this self-generating ulcer patch can accelerate cell regeneration and tissue repair, thereby promoting ulcer healing. Figure 14 As shown, the material constituting the structure of a self-generating ulcer patch can generate a 60 microamp pulsed current under continuous friction. Through continuous friction or pressure on the self-generating ulcer patch, the generated Maxwell pulsed electric field can stimulate and activate cells, causing them to migrate in a directed manner.

[0026] The following description, in conjunction with specific embodiments, illustrates this point.

The commonly used ulcer dressing layer 2 consists of a drug-containing layer and a protective layer. The drug-containing layer contains medicinal ingredients, and the protective layer is selected from one or more of polyacrylic acid resin, diethyl phthalate, or hydroxypropyl methylcellulose. The self-generating layer is connected or combined with the commonly used ulcer dressing by coating, mixing, or pressing, and then dried to form the self-generating ulcer dressing. When the self-generating ulcer dressing is continuously rubbed and pressed, the generating layer is subjected to continuous force to generate a Maxwell pulse electric field and pulse current, which can activate cells, promote blood circulation, and, synergistically with the ulcer medication, accelerate cell regeneration and tissue repair, thereby promoting ulcer wound healing.

[0030] like Figure 2 As shown, a self-generating ulcer patch in this embodiment includes a self-generating layer, preferably a polylactic acid (PLA) membrane 5, a drug-containing layer 3, and a protective layer 4. The protective layer is selected from one or more of polyacrylic acid resin, diethyl phthalate, or hydroxypropyl methylcellulose. Under external force (such as pressing or friction), the PLA membrane converts mechanical energy into electrical energy, generating a Maxwell pulse electric field that promotes cell regeneration and tissue repair. The PLA membrane, as the self-generating layer, is connected or combined with the drug-containing layer containing medicinal ingredients through coating, mixing, or tableting. The two are then bonded to the protective layer and dried to form the self-generating ulcer patch. When the self-generating ulcer patch is continuously rubbed and pressed, the generating layer is subjected to continuous force, generating a Maxwell pulse electric field and pulse current, which can activate cells, promote blood circulation, and, synergistically with the ulcer medication, accelerate cell regeneration and tissue repair, thereby promoting ulcer wound healing.

The polarized cellulose dressing film, as the self-generating layer, is connected or combined with the drug-containing layer containing medicinal ingredients through coating, mixing, or pressing. The two are then combined onto the protective layer and dried to form the self-generating ulcer patch. When the self-generating ulcer patch is continuously rubbed and pressed, the generating layer is subjected to continuous force, generating a Maxwell pulse electric field and pulse current, which can activate cells, promote blood circulation, and, synergistically with the ulcer medication, accelerate cell regeneration and tissue repair, thereby promoting ulcer wound healing.

The polarized cellulose dressing film and the polyvinyl alcohol film, as the self-generating layer, are connected or combined with the drug-containing layer containing medicinal ingredients through coating, mixing, or pressing. All three are then combined onto the protective layer and dried to form the self-generating ulcer patch. When the self-generating ulcer patch is continuously rubbed and pressed, the generating layer is subjected to continuous force, generating a Maxwell pulse electric field and pulse current, which can activate cells, promote blood circulation, and, synergistically with the ulcer medication, accelerate cell regeneration and tissue repair, thereby promoting ulcer wound healing.
