Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to an elastic bandage containing bacterial fibers and ultrafine alloy copper wires and its preparation method. Background Technology

[0002] Currently, bacterial cellulose has a large market share in medical dressings due to its extremely high hydrophilicity, biocompatibility, and purity. Existing research shows that using this biological dressing in scar treatment can maximize the maintenance of scar surface moisture and drug concentration, effectively reducing the likelihood of scar hyperplasia. However, due to the high production cost and complex process of bacterial cellulose, and the fact that bacterial cellulose dressings do not offer a significant advantage over ordinary gauze, and because bacterial cellulose is mostly produced by pressing into films rather than being drawn into fibers for textile processing, the variety of finished bacterial cellulose dressings is very limited. Therefore, it has not been widely adopted in clinical practice.

[0003] As people's quality of life continues to improve, there is a growing demand for more comfortable, convenient, and systematic treatment for scars. There is an urgent need to develop a multi-physical coupling elastic dressing product that integrates antibacterial, moisturizing, negative pressure, electrical, and magnetic therapy. Currently, there is no therapeutic dressing product that combines antibacterial bacterial cellulose, pressure, electrical stimulation, and pulsed magnetic field therapy.

[0004] Elastic bandages are widely used for external bandaging of various parts of the body, outdoor training, and first aid for injuries. The fabric should be highly elastic, non-shrinking, allow for unrestricted movement around joints, not impede blood circulation, and be non-allergenic, without affecting the user's daily life. Common elastic bandages include self-adhesive elastic bandages, spandex elastic bandages, and 100% cotton elastic bandages.

[0005] Scars undergo remodeling both during and after their formation, and external factors can influence this process, with pressure being one such factor. Pressure reduces blood supply to scar tissue, causing relative ischemia and ultimately leading to softening and thinning of the scar. Therefore, using elastic pressure bandages is highly effective in treating hypertrophic scars. Furthermore, anti-scar treatment also requires medications such as silicone gel; therefore, maintaining epidermal moisture, inhibiting bacteria, and ensuring effective coverage of the medication are also crucial considerations in dressing design.

[0006] Numerous studies have shown that low-frequency electrical stimulation can effectively promote collagen rearrangement, thereby achieving the therapeutic effect of softening scars.

[0007] Based on the above analysis, the problems and shortcomings of the existing technology are as follows:

[0008] (1) Existing bacterial cellulose processing methods do not include metal wire-linked textile products, which cannot maximize the antibacterial and moisturizing effects of bacterial cellulose.

[0009] (2) Existing elastic compression bandage treatments cannot simultaneously perform negative pressure, scar surface moisturizing, electrical stimulation, magnetic field irradiation and other treatments.

[0010] (3) Existing stimulation therapy methods are mostly single electric field stimulation, without multi-physical field coupling stimulation, resulting in limited therapeutic effects and failing to leverage the effects of physical field therapy. Summary of the Invention

[0011] To address the problems existing in the prior art, this invention provides a method for preparing an elastic bandage scar treatment system containing bacterial fibers, ultra-fine alloy copper wire, FPC flexible coil, and a pulsed magnetic field emitting device.

[0012] The present invention is achieved by using an elastic bandage containing bacterial fibers and ultra-fine alloy copper wires, which are interwoven to form a bandage. The elastic bandage is covered with a secondary receiving coil dressing to receive external primary pulse magnetic field signals.

[0013] Furthermore, the secondary receiving coil dressing is a double-layer dressing, with an FPC flexible induction coil, a positive conductive gel strip, and a negative conductive gel strip fixed in the middle of the double-layer dressing. A micro rectifier patch is fixed at the positive terminal of the FPC flexible induction coil. The positive and negative terminals of the FPC flexible induction coil are respectively fixed on both sides of the secondary receiving coil dressing and connected to the positive and negative conductive gel strips respectively.

[0014] Furthermore, the primary magnetic field emitting device is a Helmholtz magnetic field emitting device with 150 turns of coil and a diameter of 15cm, as well as a small high-frequency coil emitting device.

[0015] Furthermore, the primary magnetic field transmitting device comprises a high-power 1. Helmholtz magnetic field coil, 11. frequency converter and voltage converter control box, 2. coil support, and 4. wireless induction coil.

[0016] Furthermore, the magnetic field transmitting device includes a Helmholtz coil for generating a unidirectional pulsed magnetic field, and a high-frequency, low-power wireless induction coil for generating a low-power, high-frequency alternating magnetic field to power the FPC flexible coil in the elastic bandage.

[0017] Furthermore, the 1. Helmholtz coil is made of two equal-sized coils with a radius distance of 150 turns.

[0018] Furthermore, the high-frequency, low-power 4. wireless induction coil is a small 25-turn coil with a frequency of 2MHz and a magnetic field strength of 0 to 100µt.

[0019] Another object of the present invention is to provide a method for preparing an elastic bandage containing bacterial fibers and ultrafine alloy copper wire, wherein the method for preparing the elastic bandage containing bacterial fibers and ultrafine alloy copper wire includes:

[0020] Wet spinning is used to prepare bacterial cellulose into a spinning solution; different spinnerets with different orifice sizes are used according to different fiber production requirements, and the spun filaments pass through 3 solid baths and are simultaneously drawn to complete the production.

[0021] Furthermore, the method for preparing the elastic bandage containing bacterial fibers and ultrafine alloy copper wire further includes:

[0022] Metallic bacterial fiber thread made by twisting ultra-fine alloy copper wire with bacterial cellulose, and metallic elastic thread made by twisting ultra-fine alloy copper wire with elastic fiber, are used to make an elastic bandage by knitting equal amounts of warp and flat interlacing of metallic bacterial fiber thread and metallic elastic thread.

[0023] Furthermore, all twisting processes involve strong twisting, which forms the basis of a textile structure with good elasticity.

[0024] Based on the above technical solutions and the technical problems solved, please analyze the advantages and positive effects of the technical solution to be protected by this invention from the following aspects:

[0025] First, addressing the technical problems existing in the prior art and the difficulty in solving them, this paper closely analyzes, in conjunction with the technical solution to be protected by this invention and the results and data obtained during the research and development process, how the technical solution of this invention solves the technical problems, and the inventive technical effects brought about by solving these problems. The specific description is as follows:

[0026] This invention relates to a method for manufacturing an elastic bandage containing alloyed copper wires using bacterial cellulose as raw material, and to the field of non-contact electromagnetic thermal coupling physical field transmission technology. It discloses a method for producing bacterial cellulose and a method for manufacturing a multifunctional elastic pressure bandage integrating high moisturizing, elastic compression, antibacterial, electromagnetic thermal field stimulation, and copper ion antibacterial properties. The bacterial fiber elastic alloyed copper wire bandage dressing of this invention has functions such as high moisturizing, long-lasting maintenance of silicone gel scar coverage, continuous scar compression, non-contact electrical stimulation, magnetic stimulation, accelerated blood circulation, reduced scar congestion, antibacterial properties, and relief of itching. This invention is convenient and comfortable to use, provides comprehensive and systematic treatment for scars, greatly reduces the probability of hypertrophic scars, and has low production costs. The bacterial fiber elastic alloyed copper wire bandage of this invention will be a major breakthrough in the treatment of hypertrophic scars and has great market value in clinical applications.

[0027] Second, considering the technical solution as a whole or from a product perspective, the technical effects and advantages of the technical solution to be protected by this invention are specifically described as follows:

[0028] This invention relates to a medical bandage made of bacterial fiber elastic containing copper wire, and more particularly to an elastic electromagnetic stimulation bandage that integrates moisturizing, negative pressure, electrical stimulation, and pulsed magnetic field. This elastic bandage combines bacterial cellulose moisturizing, copper ion conductive anti-inflammatory, electrical stimulation, and pulsed magnetic field therapy into one.

[0029] This invention proposes a three-step solid bath method for processing bacterial cellulose, significantly improving its tensile strength and toughness, enabling textile processing beyond film formation. This invention can simultaneously treat scars with moisturizing, negative pressure, electrical stimulation, and pulsed magnetic fields, reducing the complexity and cost of treatment. After breast augmentation surgery, when this elastic bandage is used for fixation, a primary energy field generator can be used alone; the generated pulsed magnetic field and heat can relieve pain and reduce edema.

[0030] This invention relates to the fabrication of an FPC flexible coil, which is attached to the surface of an elastic bandage in the form of a thin film. The flexible coil is soft, thin, and foldable, and at the same time receives energy from a high-frequency, low-power small coil to generate a pulse current. By utilizing the conductivity of the bacterial fiber elastic bandage containing extremely fine copper wires, electrical stimulation of the skin surface is achieved.

[0031] Third, as supplementary evidence of the inventive step of the claims of this invention, it is also reflected in the following important aspects:

[0032] (1) The expected benefits and commercial value of the technical solution of this invention after transformation are as follows:

[0033] Bacterial cellulose elastic bandage coupled with electromagnetic field therapy, once put into production, can reduce the cost of treating hypertrophic scars from the original 200 yuan / cm². 2 The price has been reduced from 50 yuan per session to 50 yuan per session.

[0034] (2) The technical solution of this invention fills a technical gap in the industry both domestically and internationally:

[0035] Currently, there are no materials in the preparation methods of elastic bandages that combine bacterial cellulose with copper wire, and there are no reports on treatment methods that combine multiple physical fields such as electricity, magnetism, and heat with positive pressure. This invention fills a gap in current treatment techniques.

[0036] (3) The technical solution of the present invention solves a technical problem that people have long wanted to solve but have never been able to solve successfully:

[0037] This invention solves the long-standing problem of cumbersome treatment for hypertrophic scars, and can simultaneously couple multiple physical therapy methods, greatly saving treatment time and costs. Attached Figure Description

The elastic bandage combines bacterial cellulose moisturizing, copper ion conductive anti-inflammatory, electrical stimulation, and pulsed magnetic field therapy into one.

[0057] To address the problem that bacterial cellulose could only be pressed into films but not drawn into fibers for textile processing, this invention employs wet spinning.
