Description

Technical Field

[0001] This utility model relates to the field of rehabilitation and physiotherapy technology, and in particular to a low-temperature thermoplastic functional pulsed magnetic and thermotherapy device. Background Technology

[0002] In the field of rehabilitation physiotherapy, especially in fracture treatment, patients require stable support and fixation during the recovery period to avoid secondary damage. Traditional fixation methods usually use plaster casts or metal braces, but these methods have certain limitations. For example, plaster casts are heavy, have poor breathability, and patients cannot bathe or engage in activities involving water during treatment. While metal braces provide good fixation, they are not lightweight and may restrict the patient's range of motion. Fracture patients need stable support and fixation of the affected area during the recovery period to avoid secondary damage. At the same time, rehabilitation treatment is also needed for common complications such as delayed fracture healing, nonunion, and pain to promote fracture healing, accelerate the reduction of swelling, pain, callus formation, and fracture healing. Currently, there are various types of treatment devices on the market, but they also have some limitations and shortcomings. Traditional fixation braces often do not fit the patient's body well and may cause discomfort after prolonged use, affecting the patient's rehabilitation experience and treatment effect.

[0003] Currently, low-temperature thermoplastic plates are used in the field of external fixation of the human body due to their low-temperature plasticity. They play a certain role in the protection and support of bone injury rehabilitation. However, due to the long rehabilitation cycle of bone healing, the need for other physical therapy at the fracture site, and the need to remove the molded external fixation brace before treatment can begin, secondary damage to the affected tissue and fracture site is easy to occur. Therefore, there are certain limitations in the comprehensive rehabilitation treatment of fracture healing, and the patient compliance is not high.

[0004] Currently, pulsed electromagnetic field therapy has shown positive effects in clinical practice in treating common complications such as delayed fracture healing, nonunion, and pain. However, this therapy requires at least 6 hours of treatment per day, with a treatment cycle of 1 to 3 months. Most fracture healing treatment devices on the market are large-scale, which is insufficient for home rehabilitation, limiting the convenience and continuity of treatment. Some physical therapy devices may also pose an overheating risk during treatment, and their treatment efficiency needs improvement. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a pulse magnetic and thermotherapy device with low temperature thermoplastic functionality.

[0006] To achieve the above objectives, this utility model provides a low-temperature thermoplastic functional pulsed magnetic and thermotherapy device, comprising:

[0007] First heat dissipation low-temperature thermoplastic material layer, graphene heating film layer, mesh fabric layer one, mesh fabric layer two, plastic electromagnetic excitation device, temperature sensing coating;

[0008] The first heat dissipation low-temperature thermoplastic material layer has a graphene heating film layer on one side and a mesh fabric layer on the other side.

[0009] The graphene heating film layer is laminated with a mesh fabric layer on the other side, which is used to radiate heat and emit far-infrared light waves for phototherapy.

[0010] The malleable electromagnetic excitation device is disposed below the second layer of mesh fabric.

[0011] The temperature-sensitive coating is applied to one side of the malleable electromagnetic excitation device to display different colors according to different temperature ranges, thereby monitoring the temperature.

[0012] The malleable electromagnetic excitation device includes a second heat-dissipating low-temperature thermoplastic material layer and one or more flexible electromagnetic excitation coils disposed within the second heat-dissipating low-temperature thermoplastic material layer.

[0013] Preferably, one side of the mesh fabric layer is further coated with a plurality of porous medicated patches.

[0014] Preferably, the low-temperature thermoplastic functional pulsed magnetic and thermal therapy device further includes an electromagnetic excitation temperature controller. The electromagnetic excitation temperature controller includes an MCU, a magnetic stimulation coil temperature detection unit, a multi-channel flexible magnetic excitation coil control unit, a magnetic stimulation power circuit, a graphene temperature control circuit, and a signal control port one. The corresponding terminals of the MCU are electrically connected to one end of the magnetic stimulation coil temperature detection unit, the multi-channel flexible magnetic excitation coil control unit, the magnetic stimulation power circuit, and the graphene temperature control circuit, respectively. The other ends of the magnetic stimulation coil temperature detection unit, the multi-channel flexible magnetic excitation coil control unit, and the graphene temperature control circuit are all electrically connected to one end of the signal control port one. The other end of the signal control port one is also connected to a signal control port two, which is also electrically connected to the plastic electromagnetic excitation device and the graphene heating film, respectively.

[0015] Preferably, the materials of the first heat-dissipating low-temperature thermoplastic material layer and the second heat-dissipating low-temperature thermoplastic material layer both include low-temperature thermoplastic material and thermally conductive filler.

[0016] Preferably, both the first and second heat-dissipating low-temperature thermoplastic material layers have multiple holes for ventilation.

[0017] Preferably, the temperature-sensitive coating has a multi-layer structure, and each layer is composed of a temperature-sensitive material, with each layer corresponding to a different temperature change range.

[0018] The technical solution of this utility model has the following beneficial effects:

[0019] This invention relates to a low-temperature thermoplastic functional pulsed magnetic and thermal therapy device. It features far-infrared light and heat functions. Through a plastic electromagnetic exciter undergoing low-temperature thermoplasticization, it can tightly conform to a conformal, plastic fixation bracket on the affected area of ​​the human body. This creates a non-uniform, omnidirectional magnetic field or a rotating magnetic field in the surrounding space. This provides conformal support and protection during the recovery period of bone injury healing, while also improving the therapeutic effect of bone injury healing. It can also be used for local physiotherapy of limbs or other parts of the body. Under the control of the electromagnetic excitation temperature controller, it can achieve the functions of graphene far-infrared light therapy, pulsed electromagnetic field or rotating magnetic field as a single therapy, or the combined biological effects of two therapies, or the combined effects of multiple biological and pharmacological effects from a porous medicated patch, thereby improving the therapeutic effect and ease of use of fracture healing and tissue damage rehabilitation.

[0020] This utility model uses a heat-dissipating low-temperature thermoplastic plate as a fracture molding material. A graphene heating film is laminated on one side of the material, and a mesh fabric is laminated on the other side of the heating film. A mesh fabric is laminated on the other side of the material to form a low-temperature malleable plate for bone injury rehabilitation. After being heated at low temperature, the contour of the bone injury is molded at low temperature, which plays a role in fixation and support.

[0021] This utility model employs a heat-dissipating, low-temperature thermoplastic material to wrap the electromagnetic excitation coil as a malleable electromagnetic excitation device. The heat generated by the electromagnetic excitation coil is dissipated through the heat-dissipating, low-temperature thermoplastic material. A temperature-sensitive coating is sprayed on one side of the malleable electromagnetic excitation device. The temperature-sensitive coating can display different colors in different temperature ranges, and different colors indicate different temperature values, indicating the safety hazards caused by overheating. The malleable electromagnetic excitation device uses at least one or more flexible electromagnetic excitation coils arranged individually or in multiple ways according to the therapeutic needs, implementing single alternating magnetic field stimulation or rotating alternating magnetic field stimulation, thus broadening the application range of magnetic therapy for various diseases and simultaneously addressing the therapeutic effects of different diseases.

[0022] This invention utilizes an MCU in an electromagnetic excitation temperature controller to send commands to a multi-channel flexible magnetic excitation coil control unit, enabling control of one or more flexible magnetic excitation coils. This allows for the application of two different magnetic therapy techniques—rotational magnetotherapy and magnetotherapy—in a flexible, malleable physical therapy device, achieving beneficial therapeutic effects on the human body. The graphene heating film signal control port and the malleable electromagnetic excitation device control port are connected to the electromagnetic excitation temperature controller. The multi-channel flexible magnetic excitation coil control unit in the electromagnetic excitation temperature controller applies electromagnetic excitation to the excitation coils at different frequencies, generating an alternating magnetic field around the coils. This field penetrates external fixation devices (such as steel plates or plaster casts) and clothing at the patient's fracture or sprain site, achieving a series of magnetobiological effects on bones, muscles, and soft tissues through pulsed electromagnetic field (PEMF) therapy, thus treating fracture sites and soft tissue injuries.

[0023] The fourth aspect of this invention involves further bonding a porous medicated patch to one side of a fabric with a composite mesh made of a low-temperature thermoplastic composite material that has heat dissipation function. This allows the heat from the graphene heating film to heat the porous medicated patch, and through the combined effects of heat and medicine, it promotes the healing and treatment of bone injuries.

[0024] This invention utilizes the dual characteristics of graphene heating film—far-infrared spectral radiation and heating—and combines it with a low-temperature thermoplastic composite material that has heat dissipation capabilities. This solves the problem of the dual therapeutic effects of far-infrared spectral radiation and thermotherapy on tissues. Furthermore, the low-temperature thermoplastic composite material with heat dissipation function encapsulates a malleable electromagnetic excitation coil. The electromagnetic exciter then possesses malleable properties while simultaneously dissipating heat generated by the excitation coil. This provides a beneficial application for wearable, malleable, human-body-fitting electromagnetic stimulation and far-infrared thermotherapy devices in orthopedic treatment and rehabilitation.

[0025] This utility model has multiple functions: under the control of an electromagnetic excitation temperature controller, it can realize the single or superimposed functions of graphene far-infrared phototherapy, pulsed electromagnetic field therapy, rotary magnetic alternating magnetic field therapy, and extracorporeal drug therapy.

[0026] This invention is portable: traditional thermotherapy, phototherapy, and electromagnetic therapy devices are usually bulky, inconvenient to carry and store, which limits their use at home or while traveling.

[0027] This invention features a fit and wearability: traditional devices cannot accurately fit different parts of the human body, resulting in poor treatment effects.

[0028] This invention has a memory property: once a treatment area is completed, it can be restored to its original shape using the memory characteristics of the thermoplastic material, making it convenient for the next use.

[0029] This invention features comfort: the outer layer is bonded with a fabric layer, which increases comfort.

[0030] This invention has heat dissipation properties:

[0031] (1) By modifying the material of thermoplastic sheet and drilling holes, the heat dissipation and air permeability of the structure are improved;

[0032] (2) By modifying the heat dissipation properties of the thermoplastic sheet, the heat generated by the electromagnetic excitation device is dissipated, thereby improving the efficiency of generating the electromagnetic field and reducing the safety hazards to human tissue caused by excessive temperature.

[0033] This invention features safety: the temperature-sensitive coating can display different colors within different temperature ranges, with different colors representing different temperature values. When the temperature exceeds the set safety threshold, the temperature-sensitive coating will quickly change color and issue a warning signal to remind people of potential safety hazards.

[0039] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figures 1 to 5 This utility model provides a low-temperature thermoplastic functional pulse magnetic and thermal therapy device, comprising: a first heat dissipation low-temperature thermoplastic material layer 100, a graphene heating film layer 200, a mesh fabric layer 1 300, a mesh fabric layer 2 400, a plastic electromagnetic excitation device 500, and a temperature-sensitive coating.

[0041] The first heat dissipation low-temperature thermoplastic material layer 100 has a graphene heating film layer 200 on one side and a mesh fabric layer 400 on the other side.

[0042] The graphene heating film layer 200 has a mesh fabric layer 300 laminated on the other side for radiating heat and emitting far-infrared light waves for phototherapy. The graphene heating film layer 200 is used to radiate heat and emit far-infrared light waves for phototherapy. The far-infrared light is generated by the graphene heating film layer 200. These particles can emit far-infrared wavelengths of light under the action of electric current. The main wavelengths are concentrated in the range of 4μm-20μm, which is very close to the range of human body thermal radiation of 4μm-17μm. This light energy penetrates deep into muscle tissue, helping to promote blood circulation and cell regeneration. The flexible graphene heating film features electrothermal conversion: efficiently converting electrical energy into heat energy, which is then used to emit far-infrared rays for thermotherapy. It also emits far-infrared rays: when powered on, it emits far-infrared rays with wavelengths matching the absorption of human tissue, helping to promote blood circulation and wound healing. Furthermore, the flexible graphene heating film is flexible: it can bend and conform to the natural shape of the human body, increasing comfort. It is also transparent: it can be designed to be transparent or translucent, allowing visible and near-infrared light to penetrate for phototherapy effects. The flexible graphene heating film has a high thermal conductivity, contributing to uniform heat distribution. Its temperature can be adjusted via control circuitry to meet different treatment needs. Finally, the flexible graphene heating film is combined with a temperature-sensitive coating to monitor and display the operating temperature.

[0043] The malleable electromagnetic excitation device 500 is disposed below the mesh fabric layer 400; wherein the light-transmitting mesh fabric serves as the outer layer, providing comfort when in contact with the human body and protecting the durability of the inner layer; the light-transmitting mesh fabric has the following characteristics: light transmittance: allowing light of specific wavelengths (such as visible light and near-infrared light) to pass through to achieve phototherapy effects; softness: providing a soft touch when in contact with the skin, increasing user comfort; breathability: allowing air circulation, reducing stuffiness and moisture accumulation when wearing; durability: having a certain degree of abrasion resistance and tensile strength to adapt to daily use and repeated wear, and able to withstand wear and stretching during daily use; decorative: different colors, patterns, or textures can be used according to design requirements to enhance the appearance of the product; the light-transmitting mesh fabric is made of skin-friendly materials to reduce potential skin irritation;

[0044] The temperature-sensitive coating (not shown in the figure) is applied to one side of the malleable electromagnetic excitation device 500 to display different colors according to different temperature ranges, thereby monitoring the temperature. The temperature-sensitive coating has a multi-layer structure, with each layer composed of temperature-sensitive material and each layer corresponding to a different temperature range. The color change of the temperature-sensitive coating is reversible, allowing the coating to return to its original color state after the temperature decreases. The color change of the temperature-sensitive coating can be directly observed with the naked eye without the need for additional equipment or tools. The color change of the temperature-sensitive coating provides an intuitive means of temperature monitoring, enhancing the user's understanding of the device's operating status. The color change of the temperature-sensitive coating includes, but is not limited to, changing from colorless to colored, or changing from one color to another, and the color change is reversible when the temperature drops below a threshold. The temperature-sensitive coating comprises at least two temperature-sensitive layers. The first layer changes color within a lower temperature range to indicate a safe temperature state, while the second layer changes color within a higher temperature range to issue an overheat warning. When the temperature exceeds a preset threshold of the second layer, the temperature-sensitive coating rapidly changes from the color of the first layer to the color of the second layer to provide an immediate visual warning. The temperature-sensitive coating is applied directly to the lower surface of the flexible PCB board layer via spraying, coating, or other similar coating techniques. The color change of the temperature-sensitive coating is unaffected by external light conditions, ensuring clear visibility under various lighting environments.

[0045] The flexible electromagnetic excitation device 500 includes a second heat-dissipating low-temperature thermoplastic material layer 501 and one or more flexible electromagnetic excitation coils 502 disposed within the second heat-dissipating low-temperature thermoplastic material layer 501. The one or more flexible electromagnetic excitation coils 502 can be arranged individually or in multiple configurations according to the therapeutic needs, implementing single alternating magnetic field stimulation or rotating alternating magnetic field stimulation. This broadens the application range of magnetotherapy for various diseases and simultaneously addresses the therapeutic effects of different conditions. When there is only one flexible electromagnetic excitation coil 502, single alternating magnetic field stimulation is used for treatment; when there are multiple flexible electromagnetic excitation coils 502, rotating alternating magnetic field stimulation is used for treatment. The flexible electromagnetic excitation coils 502 are controlled by a multi-channel flexible magnetic excitation coil control unit 604 to achieve different magnetic field stimulation modes. The flexible electromagnetic excitation coils 502 are designed to generate single alternating magnetic fields or rotating alternating magnetic fields to adapt to different therapeutic purposes.

[0046] In this embodiment, a first heat-dissipating low-temperature thermoplastic material layer 100 is used as the fracture molding material. A graphene heating film layer 200 is laminated on one side of the first heat-dissipating low-temperature thermoplastic material layer 100, and a mesh fabric layer 300 is laminated on the other side of the graphene heating film layer 200. A second mesh fabric layer 400 is laminated on the other side of the first heat-dissipating low-temperature thermoplastic material layer 100 to form a low-temperature malleable plate for bone injury rehabilitation. After being heated at low temperature, the contour of the bone injury site is formed at low temperature, which plays a role in fixation and support.

[0047] The second type uses a flexible electromagnetic excitation coil 502 wrapped with a second heat dissipation low-temperature thermoplastic material layer 501 as a plastic electromagnetic excitation device 500. The heat generated by the flexible electromagnetic excitation coil 502 is dissipated through the second heat dissipation low-temperature thermoplastic material layer 501. A temperature-sensitive coating is sprayed on one side of the plastic electromagnetic excitation device 500. The temperature-sensitive coating can display different colors in different temperature ranges. Different colors indicate different temperature values ​​and indicate the safety hazards caused by overheating.

[0048] The malleable electromagnetic excitation device 500 employs at least one or more flexible electromagnetic excitation coils 501 arranged individually or in multiple ways to meet the therapeutic needs, implementing single alternating magnetic field stimulation or rotating alternating magnetic field stimulation, thereby broadening the application range of magnetotherapy for a variety of diseases and simultaneously addressing the therapeutic effects of different diseases.

[0049] Furthermore, both the first heat-dissipating low-temperature thermoplastic material layer 100 and the second heat-dissipating low-temperature thermoplastic material layer 501 are provided with multiple holes 301 for ventilation, which can further improve the heat dissipation and ventilation performance of the board.

[0050] Furthermore, the surface of the mesh fabric layer 300 is also coated with several porous medicated patches (not shown in the figure), which allow the heat from the graphene heating film layer 200 to heat the porous medicated patches. Through the combined effects of heat and medication, this promotes bone injury healing. The mesh fabric layer 300 provides good breathability, helping to maintain skin respiration at the treatment site, reducing moisture and heat accumulation, and improving wearing comfort. As a carrier for the porous medicated patches, the mesh fabric layer 300 can stably fix the patches, ensuring that the medication acts directly on the treatment area. The softness and elasticity of the mesh fabric layer 300 allow it to adapt to different body shapes, providing a more fitting treatment experience. In this embodiment, the porous medicated patch serves the following functions: Sustained drug release: The porous medicated patch is designed to contain the required medication and has a porous structure, allowing for controlled and gradual release of the drug, prolonging its duration of action; Local treatment: The porous medicated patch can be applied directly to the affected area, reducing systemic side effects and improving treatment efficacy; Enhanced absorption: The porous structure helps the drug components penetrate the skin better, improving absorption rate and bioavailability. The combination of the mesh fabric layer 300 and the porous medicated patch provides a comprehensive treatment method, combining electromagnetic stimulation and drug therapy to enhance therapeutic effects. The type and dosage of medication in the porous medicated patch can be adjusted according to different treatment needs, achieving personalized treatment. The controlled release mechanism of the porous medicated patch can avoid drug overdose, reduce adverse reactions, and improve treatment safety.

[0051] Furthermore, the low-temperature thermoplastic functional pulsed magnetic and thermal therapy device also includes an electromagnetic excitation temperature controller. The electromagnetic excitation temperature controller 600 includes an MCU 601, a magnetic stimulation coil temperature detection unit 602, a multi-channel flexible magnetic excitation coil control unit 604, a magnetic stimulation power circuit 603, a graphene temperature control circuit 605, and a signal control port 606. The corresponding terminals of the MCU are electrically connected to one end of the magnetic stimulation coil temperature detection unit 602, the multi-channel flexible magnetic excitation coil control unit 604, the magnetic stimulation power circuit 603, and the graphene temperature control circuit 605. The magnetic stimulation coil temperature detection unit 602, the multi-channel flexible magnetic excitation coil control unit 604, the graphene temperature control circuit 605, and the graphene temperature control circuit 606 are all electrically connected to one end of each of these components. The other end of the graphene temperature control circuit 605 is electrically connected to one end of signal control port 606. The other end of signal control port 606 is also connected to signal control port 520, which is also electrically connected to the plastic electromagnetic excitation device 500 and the graphene heating film 200. The electromagnetic excitation temperature controller 600 also includes a lithium battery 608 and a lithium battery management circuit 607. The lithium battery 608 is electrically connected to the corresponding end of the MCU through the lithium battery management circuit 607 to supply power to the MCU.

[0052] The MCU 601 (Microcontroller Unit) acts as the brain of the entire electromagnetic excitation temperature controller, responsible for receiving input signals, executing program instructions, and controlling the working status of other components. Precise control by the MCU 601 ensures the stability and reliability of the treatment process, while improving energy efficiency and therapeutic effect. The magnetic stimulation coil temperature detection unit 602 monitors the temperature of the flexible magnetic excitation coil 502, ensuring it operates within a safe temperature range to prevent tissue damage caused by overheating and improve treatment safety. The multi-channel flexible magnetic excitation coil control unit 604 controls the current and frequency of one or more flexible magnetic excitation coils 502 to generate the required electromagnetic field, allowing the treatment device to adapt to different treatment needs and improving treatment flexibility and effectiveness. The magnetic stimulation power circuit 603 provides stable and adjustable power to the flexible magnetic excitation coil 502, ensuring the electromagnetic field strength meets treatment requirements. Precise control of the electromagnetic field strength... This design optimizes treatment effectiveness while reducing unnecessary energy consumption. The graphene temperature control circuit 605 controls the temperature of the graphene heating film 200 to provide appropriate thermotherapy. Precise temperature control of the graphene heating film helps improve the safety and effectiveness of thermotherapy. Signal control port 1 606 serves as the communication interface between the electromagnetic excitation temperature controller 600, the malleable electromagnetic excitation device 500, and the graphene heating film 200. Through signal control port 1 606, remote control and monitoring of the treatment device can be achieved, improving operational convenience. Signal control port 2 520 connects the malleable electromagnetic excitation device 500 and the graphene heating film 200, enabling precise control of these devices and ensuring they work synchronously with the controller 600. The use of signal control ports allows the controller to precisely control the operating status of each component, including temperature, power, and operating mode, thereby providing a personalized and optimized treatment experience. Through the access of external signals, users or medical professionals can more easily interact with the treatment device to monitor and adjust the treatment process. In this embodiment, the MCU in the electromagnetic excitation temperature controller 600 sends commands to the multi-channel flexible magnetic excitation coil control unit 604 to control one or more flexible magnetic excitation coils 502. This enables the flexible and malleable physical therapy device to achieve the beneficial effects of two different magnetic therapy techniques, rotational magnetotherapy and magnetotherapy, on the human body. The graphene heating film signal control port 2 and the malleable electromagnetic excitation device control port 2 are connected to the electromagnetic excitation temperature controller 600. The multi-channel flexible magnetic excitation coil control unit 604 electromagnetically excites the flexible magnetic excitation coils 502 at different frequencies, generating an alternating magnetic field around the coil. This magnetic field penetrates the fixation objects (such as steel plates, plaster casts) and clothing outside the patient's fracture or sprain site, achieving a series of magnetobiological effects on bones, muscles, and soft tissues through pulsed electromagnetic field (PEMF) therapy, thus achieving the therapeutic effect on fracture sites and soft tissue injuries.

[0053] Furthermore, both the first heat-dissipating low-temperature thermoplastic material layer 100 and the second heat-dissipating low-temperature thermoplastic material layer 501 are composed of low-temperature thermoplastic materials and thermally conductive fillers. The low-temperature thermoplastic material is made of a special polymer material and has shape memory properties. It can soften and be shaped according to the user's shape within a temperature range of 40℃-60℃, and retain its shape after cooling. The thermally conductive filler is selected from graphite, silicon carbide, silicon nitride, carbon nanotubes, graphene, etc., all of which have high thermal conductivity and extremely high thermal conductivity. When these materials are used as fillers in plastic modification, they can significantly improve the thermal conductivity of composite materials. Compared with traditional thermoplastic materials, low-temperature thermoplastic materials are generally lighter and suitable for wearable devices.

[0054] This embodiment also provides a method for preparing a low-temperature thermoplastic functional pulsed magnetic and thermotherapy device, comprising the following steps:

[0055] Step S1: After uniformly mixing the low-temperature thermoplastic material with the thermally conductive filler, the mixture is extruded through a twin-screw extruder to obtain a heat-dissipating low-temperature thermoplastic material layer. Alternatively, after uniformly mixing the low-temperature thermoplastic material with the thermally conductive filler, the mixture is extruded through a twin-screw extruder and then uniformly extruded with a three-dimensional mesh fabric to obtain a thermally conductive low-temperature thermoplastic material layer. The weight ratio of the thermally conductive filler is 5-20% of the low-temperature thermoplastic material. In step S1, the addition of the thermally conductive filler can significantly improve the thermal conductivity of the low-temperature thermoplastic material. The improved thermal conductivity helps to more effectively transfer heat to the body parts that need treatment, enhancing the therapeutic effect. As a result, improved thermal conductivity helps to dissipate heat generated by the light source more effectively, preventing equipment overheating and improving safety; it forms a uniform composite material: the blending process ensures that the thermally conductive filler is evenly distributed in the low-temperature thermoplastic material, thereby obtaining a composite material with consistent performance. By adjusting the proportion of thermally conductive filler, customized materials with specific thermal conductivity requirements can be manufactured to optimize the softness and comfort of the material, making it more suitable for wearing; using a twin-screw extruder enables continuous production, improving production efficiency and reducing costs. The blending and extrusion processes can be carried out under controlled conditions, ensuring the quality and consistency of each batch of products;

[0056] Step S2: The first heat-dissipating low-temperature thermoplastic material layer 100 and the graphene heating film layer 200 are bonded together by hot pressing using a hot press. This step S2 uses hot pressing to bond the first heat-dissipating low-temperature thermoplastic material layer 100 and the graphene heating film layer 200. This hot pressing ensures heat transfer between the low-temperature thermoplastic material layer and the heating film. The hot pressing conditions are precisely controlled according to the material properties of the first heat-dissipating low-temperature thermoplastic material layer 100 and the graphene heating film layer. The resulting bonded structure has high durability and stability, suitable for long-term wear and repeated use, enabling the graphene heating film layer 200 to provide a uniform heat therapy effect. The bonded heat-conducting layer can quickly and uniformly transfer the heat generated by the graphene heating film to the entire surface, improving heat conduction efficiency. The addition of the graphene heating film layer 200 provides a soft and adaptable heat therapy layer, increasing comfort during wear. Optimized heat therapy effects provide uniform and effective heat therapy, helping to relieve pain, promote blood circulation, and accelerate the healing process.

[0057] Step S3: The first heat-dissipating low-temperature thermoplastic material layer 100 and the second heat-dissipating low-temperature thermoplastic material layer 501 are perforated to facilitate ventilation and heat dissipation. The perforation process forms holes in the heat-dissipating low-temperature thermoplastic material layer, allowing air to circulate, improving breathability and comfort when wearing. By removing some material through the perforation, the total weight of the device can be reduced, making it more suitable for wearing. The holes increase the discharge of hot air, which helps to dissipate heat and improve heat dissipation efficiency.

[0058] Step S4: The second heat-dissipating low-temperature thermoplastic material layer 501 wraps the flexible electromagnetic excitation coil 502, and the heat generated by the flexible electromagnetic excitation coil 502 is dissipated through the second heat-dissipating low-temperature thermoplastic material layer 501. The method of wrapping the flexible electromagnetic excitation coil 502 using the second heat-dissipating low-temperature thermoplastic material layer 501 includes the following steps: Material preparation: Ensure that the surfaces of the second heat-dissipating low-temperature thermoplastic material layer 501 and the flexible electromagnetic excitation coil 502 are clean and undamaged, suitable for subsequent wrapping operations; Wrapping structure design: Design the layout and shape of the second heat-dissipating low-temperature thermoplastic material layer 501 according to the shape and size of the flexible electromagnetic excitation coil 502 to achieve the best wrapping effect; Heating and softening. The process involves: heating the second heat-dissipating low-temperature thermoplastic material layer 501 to its softening point to give it sufficient flexibility and plasticity for wrapping the coil; precise wrapping: attaching the heated and softened second heat-dissipating low-temperature thermoplastic material layer 501 to the surface of the flexible electromagnetic excitation coil 502 according to a predetermined shape; ensuring that the material layer evenly covers every part of the coil without gaps to achieve optimal heat dissipation and protection; curing and shaping: maintaining the coil under certain pressure and temperature for a period of time to allow the second heat-dissipating low-temperature thermoplastic material layer 501 to cure and shape, tightly adhering to the coil; cooling and inspection: after cooling, inspecting the wrapped flexible electromagnetic excitation coil 502 to ensure that the uniformity of the wrapping layer, adhesion strength, and heat dissipation performance meet the design requirements. Functions and benefits: Enhanced heat dissipation: Due to its heat dissipation characteristics, the second heat-dissipating low-temperature thermoplastic material layer 501 can effectively dissipate the heat generated by the flexible electromagnetic excitation coil 502 during operation, improving the thermal stability and safety of the entire treatment device; Protection of the electromagnetic coil: The wrapping layer not only dissipates heat but also provides physical protection for the coil, preventing external impacts and wear, and extending the coil's service life; Improved wearing comfort: The softness and plasticity of the second heat-dissipating low-temperature thermoplastic material layer 501 allow it to comfortably conform to the wearer's body, improving comfort during treatment; Optimized electromagnetic field distribution: Through precise wrapping, the electromagnetic field distribution generated by the flexible electromagnetic excitation coil 502 can be optimized, improving the treatment effect.

[0059] Step S5: Adhere the second mesh fabric layer between the first heat-dissipating low-temperature thermoplastic material layer and the second heat-dissipating low-temperature thermoplastic material layer;

[0060] Step S6: Then, adhere the first mesh fabric layer to the surface of the graphene heating film layer, and composite the porous medicated patch onto the first mesh fabric layer;

[0061] Step S7: Finally, spray a temperature-sensitive coating onto the second heat-dissipating low-temperature thermoplastic material layer.

[0062] This embodiment presents a low-temperature thermoplastic functional pulsed magnetic and thermal therapy device with far-infrared light and heat functions. After low-temperature thermoplasticization via a plastic electromagnetic exciter, it can closely conform to a conformal plastic fixation frame on the affected area of ​​the human body. This creates a non-uniform, non-directional magnetic field or a rotating magnetic field in the surrounding space. This fulfills the function of conformal support and protection during the rehabilitation period of bone injury healing, while simultaneously improving the therapeutic effect of bone injury healing. It can also be applied to local physiotherapy of limbs or other parts of the body. Under the control of the electromagnetic excitation temperature controller 600, it can achieve the functions of graphene far-infrared light therapy, pulsed electromagnetic field or rotating magnetic field single therapy, or the combined biological effects of two therapies, or the combined effects of multiple biological and pharmacological effects from porous medicated patches. This improves the efficacy and ease of use of fracture healing, tissue damage rehabilitation treatment.

[0063] Working principle of this utility model:

[0064] The treatment device should be tailored to the needs of the treatment area;

[0065] The cut treatment device was softened in an environment of 40℃-70℃.

[0066] Apply the softened treatment device to the area requiring treatment;

[0067] After the material hardens, apply it to the body part.

[0068] Trim off any excess material to ensure the treatment device fits snugly against the skin;

[0069] Connect to an electromagnetic excitation temperature controller for physiotherapy.

[0070] As can be seen from the above embodiments, the present invention provides a low-temperature thermoplastic functional pulsed magnetic and thermal therapy device with far-infrared light and heat functions. After low-temperature thermoplasticization via a plastic electromagnetic exciter, it can closely conform to a conformal plastic fixation bracket on the affected area of ​​the human body. This results in a non-uniform, non-directional magnetic field or a rotating magnetic alternating magnetic field generated in the surrounding space. This fulfills the function of conformal support and protection during the rehabilitation period of bone injury healing, while simultaneously improving the therapeutic effect of bone injury healing. It can also be applied to local physiotherapy of limbs or other parts of the human body. Under the control of the electromagnetic excitation temperature controller, it can achieve the functions of graphene far-infrared light therapy, pulsed electromagnetic field or rotating magnetic alternating magnetic field as a single therapy, or the combined biological effects of two therapies, or the combined effects of multiple biological and pharmacological effects of porous medicated patches, thereby improving the therapeutic effect and ease of use of fracture healing and tissue damage rehabilitation.

[0071] This utility model uses a heat-dissipating low-temperature thermoplastic plate as a fracture molding material. A graphene heating film is laminated on one side of the material, and a mesh fabric is laminated on the other side of the heating film. A mesh fabric is laminated on the other side of the material to form a low-temperature malleable plate for bone injury rehabilitation. After being heated at low temperature, the contour of the bone injury is molded at low temperature, which plays a role in fixation and support.

[0072] This utility model employs a heat-dissipating, low-temperature thermoplastic material to wrap the electromagnetic excitation coil as a malleable electromagnetic excitation device. The heat generated by the electromagnetic excitation coil is dissipated through the heat-dissipating, low-temperature thermoplastic material. A temperature-sensitive coating is sprayed on one side of the malleable electromagnetic excitation device. The temperature-sensitive coating can display different colors in different temperature ranges, and different colors indicate different temperature values, indicating the safety hazards caused by overheating. The malleable electromagnetic excitation device uses at least one or more flexible electromagnetic excitation coils arranged individually or in multiple ways according to the therapeutic needs, implementing single alternating magnetic field stimulation or rotating alternating magnetic field stimulation, thus broadening the application range of magnetic therapy for various diseases and simultaneously addressing the therapeutic effects of different diseases.

[0073] This invention utilizes an MCU in an electromagnetic excitation temperature controller to send commands to a multi-channel flexible magnetic excitation coil control unit, enabling control of one or more flexible magnetic excitation coils. This allows for the application of two different magnetic therapy techniques—rotational magnetotherapy and magnetotherapy—in a flexible, malleable physical therapy device, achieving beneficial therapeutic effects on the human body. The graphene heating film signal control port and the malleable electromagnetic excitation device control port are connected to the electromagnetic excitation temperature controller. The multi-channel flexible magnetic excitation coil control unit in the electromagnetic excitation temperature controller applies electromagnetic excitation to the excitation coils at different frequencies, generating an alternating magnetic field around the coils. This field penetrates external fixation devices (such as steel plates or plaster casts) and clothing at the patient's fracture or sprain site, achieving a series of magnetobiological effects on bones, muscles, and soft tissues through pulsed electromagnetic field (PEMF) therapy, thus treating fracture sites and soft tissue injuries.

[0074] The fourth aspect of this invention involves further bonding a porous medicated patch to one side of a fabric with a composite mesh made of a low-temperature thermoplastic composite material that has heat dissipation function. This allows the heat from the graphene heating film to heat the porous medicated patch, and through the combined effects of heat and medicine, it promotes the healing and treatment of bone injuries.

[0075] This invention utilizes the dual characteristics of graphene heating film—far-infrared spectral radiation and heating—and combines it with a low-temperature thermoplastic composite material that has heat dissipation capabilities. This solves the problem of the dual therapeutic effects of far-infrared spectral radiation and thermotherapy on tissues. Furthermore, the low-temperature thermoplastic composite material with heat dissipation function encapsulates a malleable electromagnetic excitation coil. The electromagnetic exciter then possesses malleable properties while simultaneously dissipating heat generated by the excitation coil. This provides a beneficial application for wearable, malleable, human-body-fitting electromagnetic stimulation and far-infrared thermotherapy devices in orthopedic treatment and rehabilitation.

[0076] This utility model has multiple functions: under the control of an electromagnetic excitation temperature controller, it can realize the single or superimposed functions of graphene far-infrared phototherapy, pulsed electromagnetic field therapy, rotary magnetic alternating magnetic field therapy, and extracorporeal drug therapy.

[0077] This invention is portable: traditional thermotherapy, phototherapy, and electromagnetic therapy devices are usually bulky, inconvenient to carry and store, which limits their use at home or while traveling.

[0078] This invention features a fit and wearability: traditional devices cannot accurately fit different parts of the human body, resulting in poor treatment effects.

[0079] This invention has a memory property: once a treatment area is completed, it can be restored to its original shape using the memory characteristics of the thermoplastic material, making it convenient for the next use.

[0080] This invention features comfort: the outer layer is bonded with a fabric layer, which increases comfort.

[0081] This invention has heat dissipation properties:

[0082] (1) By modifying the material of thermoplastic sheet and drilling holes, the heat dissipation and air permeability of the structure are improved;

[0083] (2) By modifying the heat dissipation of the thermoplastic board material, the heat generated by the electromagnetic excitation device is dissipated, and the efficiency of generating the electromagnetic field is improved, while reducing the safety hazards to human tissue caused by excessive temperature.

[0084] This invention features safety: the temperature-sensitive coating can display different colors within different temperature ranges, with different colors representing different temperature values. When the temperature exceeds the set safety threshold, the temperature-sensitive coating will quickly change color and issue a warning signal to remind people of potential safety hazards.

[0085] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
