Description

Technical Field

[0001] This invention relates to the field of biomedical technology, specifically to a fat reduction device and system utilizing low- to medium-frequency magnetic pulses. Background Technology

[0002] With economic development, scientific advancement, social progress, and intensified competition, more and more people hope to change their appearance through cosmetic surgery. In recent years, my country's cosmetic surgery industry has developed rapidly, demonstrating enormous market potential. Currently, the market size of cosmetic medical institutions in my country exceeds 450 billion yuan, with more than 30 million employees. my country's cosmetic surgery industry is growing at an annual rate of 20%, and cosmetic surgery procedures are growing at a rate of over 20% annually. Over the past 20 years, my country's medical aesthetics industry has developed into a vast, comprehensive industrial chain encompassing medical plastic surgery, medical aesthetics, and injectable cosmetic procedures.

[0003] In fact, patients demand rapid, non-invasive treatments and methods that deliver satisfactory results with minimal risk. The most common non-invasive cosmetic applications are mechanical wave methods, such as ultrasound or shockwave therapy; electromagnetic wave methods, such as radiofrequency therapy; and light therapy, such as intense pulsed light or laser therapy. The effects of mechanical waves on tissues are based on cavitation, vibration, or thermal induction effects. Electromagnetic wave therapy is based on the thermal effects of electromagnetic waves on biological structures, enhancing the visual appearance of the skin by increasing the production of collagen and elastin, smoothing the skin, or reducing cellulite and fat cells. However, mechanical treatments have significant drawbacks, such as the risk of panniculitis or heterogeneous results. Thermal therapy includes several disadvantages, such as the risk of overheating or thermal damage to the patient, panniculitis, or heterogeneous results. Mechanical wave or thermal treatments do not improve the visual appearance of muscles, such as muscle shaping, toning, or plumping effects.

[0004] Existing medical aesthetic fat reduction devices offer a poor user experience. Different users have different needs, and different people in different areas have different obesity conditions, resulting in a lack of targeted treatment. Summary of the Invention

[0005] The main technical problem solved by this invention is that the existing fat reduction devices have poor user experience and lack targeted treatment for specific areas.

The fat reduction device includes a communication module for communicating with the external terminal and acquiring control signals sent by the external terminal. The control module of the fat reduction device is used to acquire the control signals and control the low-frequency magnetic pulse generation module of the fat reduction device to work and / or control the medium-frequency magnetic pulse generation module of the fat reduction device to work under the triggering of the control signals.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings. Similar elements in different embodiments are referred to by associated similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of this application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to this application are not shown or described in the specification. This is to avoid obscuring the core parts of this application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0025] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0026] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0027] Transcranial magnetic stimulation (TMS) is a neurostimulation and neuromodulation technique based on the principle of induction of electromagnetic electric fields in the brain. In recent years, it has been expanded to the rehabilitation of the entire nervous system and peripheral tissues. The induced electric fields generated by the magnetic field have sufficient strength and density to depolarize neurons, and when TMS pulses are repeatedly applied, they can modulate cortical excitability, depending on the stimulation parameters, and even modulate cortical excitability throughout the stimulation period. This gives TMS the potential to modulate neural function.

[0028] Electric field stimulation, such as TTFields and transcranial alternating current (TCD), and TMS all essentially use electric fields to influence tissues or cells, but they differ in their specific applications. Electric field stimulation involves directly applying an alternating electric field between electrodes. This can lead to poor treatment efficacy due to impedance differences between different layers of body tissue, making it difficult to focus the stimulation on specific tissue layers and areas. It may also cause overstimulation of unrelated tissues, resulting in inflammation, pain, and damage. Electric field stimulation, such as TMS and MST, emphasizes using the induced electric field generated by the alternating magnetic field in body tissue to depolarize or hyperpolarize cells and regulate cell function. TTFields utilizes the ability of an electric field to deflect or displace polarized or charged particles in the electric field, thereby interfering with the division of cancer cells and causing them to die.

[0029] Existing mechanical wave fat reduction and beauty devices employ ultrasound or shock wave therapy, typically delivered via conventional ultrasound transducers composed of piezoelectric materials, such as lead zirconate titanate (PZT), where the applied potential causes mechanical displacement. Conventional ultrasound transducers are usually driven by resonant body wave mode, with frequencies typically ranging from a few kHz to a few MHz, and energy is coupled from the transducer to adjacent body tissues. However, this driving mode has several limitations: (1) The resonant body waves within the piezoelectric material dissipate some energy as heat, causing the ultrasound element to self-heat. This heating can irritate or even burn the skin, especially when the transducer is operating at high intensity, and also reduces device efficiency. (2) The size and enormous power requirements of conventional ultrasound transducers hinder their application as wearable or portable fat reduction and beauty devices for precise body contouring. (3) Natural nano / microbubbles in living body tissues oscillate with the application of ultrasound in the frequency range of a few kHz to a few MHz and can collapse rapidly, resulting in shock waves (i.e., inertial cavitation). The shockwaves caused by cavitation within tissues, especially nerve tissue in the skin, are dangerous to neurons in living tissue and can lead to nerve cell death. This limits the maximum safe operating power of ultrasonic fat reduction beauty devices, potentially limiting the efficiency and effectiveness of producing optimal weight loss and body shaping results.

[0030] In this application, the target area refers to the area or region where the user needs to achieve fat reduction and body shaping, such as the abdomen, legs, and chest; it can also be understood as human tissue. The detection image is an image taken directly at the target area, and the human eye or image recognition algorithm can determine which part of the human body the target area belongs to.

[0031] In this embodiment of the invention, a combination of low-frequency and medium-frequency magnetic fields is used to perform targeted fat reduction and cosmetic treatment on the treatment area, overcoming the traditional mechanical wave treatment method and improving the user experience and treatment effect (i.e., fat reduction effect).

[0032] Example 1:

[0033] Please refer to Figure 1 A fat reduction device utilizing low- and medium-frequency magnetic pulses includes: an image acquisition module 1, a low-frequency magnetic pulse generation module 2, a medium-frequency magnetic pulse generation module 3, and a control module 4.

[0034] Image acquisition module 1 is used to acquire detection images of the user's target area.

[0035] The low-frequency magnetic pulse generating module 2 generates a magnetic field with a first preset frequency and a first preset intensity; the medium-frequency magnetic pulse generating module 3 generates a magnetic field with a second preset frequency and a second preset intensity; wherein the first preset frequency is lower than the second preset frequency, and the first preset intensity is greater than the second preset intensity. In this embodiment, a coil is used to generate the magnetic field. The alternating therapeutic magnetic field combining medium and low frequencies can reduce the number or size of fat cells in the treated area, and strengthen the contraction of muscles in the treated area and adjacent areas, resulting in more aesthetically pleasing muscle strengthening and shaping.

[0036] The control module 4 is used to determine the action parameters of the target part based on the detected image. The action parameters include the action position, the first working parameter and the second working parameter. The first working parameter includes the first action time, the first preset frequency and the first preset intensity. The second working parameter includes the second action time, the second preset frequency and the second preset intensity. The control module 4 is also used to control the low-frequency magnetic pulse generation module 2 to work according to the first working parameter and to control the medium-frequency magnetic pulse generation module 3 to work according to the second working parameter.

[0037] The fat reduction device provided in this embodiment uses a low-frequency magnetic field below 1kHz to stimulate body tissues, such as the limbs, abdomen, buttocks, waist, and face. When the magnetic field strength is sufficiently high, reaching several Tesla, it will stimulate nerves, muscles, and other related tissues by causing membrane depolarization. The most obvious effect is that it causes involuntary tremors and vibrations of the muscles in the stimulated area, resulting in a large amount of energy consumption and localized weight loss. Moreover, this frequency range is also the operating frequency of conventional transcranial magnetic stimulation, which is a safe electromagnetic field frequency range and will not cause damage to body tissues, pain, or other adverse effects. At the same time, this electromagnetic field frequency range (i.e., the TMS frequency range) can stimulate related body nerve tissues, optimize the function of body nerve tissues, and achieve the effect of improving health.

[0038] On the other hand, mid-frequency magnetic pulses are used to stimulate superficial tissues of the body, such as the limbs, abdomen, buttocks, waist, and face. The frequency is between 500kHz and 1000kHz, and the intensity is between 1mT and 5mT. This generates an induced electric field in the skin layer and the shallow area under the skin that is basically the same as that generated by TTFields, achieving the same therapeutic effect. For example, it can prevent the disordered division of unconventional cells (e.g., the excessive growth and deposition of skin pigment cells, the pathological tendency of body tissues, the excessive growth of fat cells, etc.). The alternating electric field will exert alternating electric field force on substances with natural electrical properties in the tissue (mainly cellular proteins such as tubulin and diaphragm proteins), causing micro-vibrations in the corresponding tissue cells and intracellular structures. Combined with the body's self-repair mechanism, this allows the body tissues to migrate in the direction of body structure optimization, achieving body tissue remodeling and body shaping effects. Meanwhile, mid-frequency magnetic pulse stimulation can increase the permeability of cell membranes in body tissues and activate calcium channels, which can improve the delivery efficiency of bioactive drugs. If used in combination with potential topical weight loss and skin beautifying drugs, it can enhance the efficacy of weight loss drugs, such as greatly improving the efficiency and effect of skin hydration.

[0039] This invention provides a fat reduction device that utilizes low- and mid-frequency magnetic pulses for fat reduction, body shaping, and cosmetic purposes. On one hand, this device induces high-intensity and high-frequency muscle contractions, resulting in a more effective reduction in the number and volume of fat cells and a change in the visual appearance of the treated body area through targeted muscle contraction exercises. Furthermore, the magnetic pulse treatment achieves temperature uniformity at the target site, overcoming the risk of thermal damage. This tissue and method induces the remodeling and regeneration of collagen and elastin fibers in the treated tissue, leading to firmer and more youthful skin at the target site. This fat reduction device can be combined with other treatment methods such as heat treatment and light treatment. The combination of heating and cooling may increase the apoptosis index, increase muscle thickness, induce apoptosis, and cause necrosis of target biological structures (such as fat cells). The remodeling of target biological structures is more pronounced, significantly shortening treatment time. In addition, side effects such as swelling and inflammation can be reduced or eliminated.

[0040] On the other hand, the fat reduction device provided in this embodiment also acquires images of the target area through the image acquisition module 1, uses relevant algorithms to optimize the optimal placement of the treatment coil (corresponding to the first coil 21 or the second coil 31) and the optimal magnetic field generation mode, and provides image comparison evidence of the treatment effect.

[0041] Image recognition algorithms can be used to determine which part of the body the target area is by detecting the image. For example, template matching algorithms can be used. Users usually have their own expected body shape, corresponding to a specific height and body fat percentage. At this time, there can be a standard image (or expected body shape image) for this expected body shape. By comparing the detected image with the standard image, the size or degree of fat reduction to be achieved in the target area (i.e., the area to be treated) can be obtained. Then, appropriate treatment parameters can be used for fat reduction and body shaping. The low-frequency magnetic pulse generation module 2 and the medium-frequency magnetic pulse generation module 3 are controlled to generate appropriate low-frequency magnetic fields to achieve better fat reduction results.

[0042] Specifically, such as Figure 2 and Figure 3 As shown, control module 4 is also used to acquire the user's basic body information, which may include the user's height, weight, age, and gender. Based on the basic body information, a desired morphological image is obtained. Control module 4 is also used to match the detected image with images in a preset morphological image library to obtain the current morphological image of the target area. Based on the current morphological image and the desired morphological image, the action parameters of the target area are determined. The morphological image can be a simple contour image; the specific area and the degree of obesity can be determined through the outline.

[0043] In real life, the normal body fat percentage for men is 15%-18%, and for women it is 20%-25%. Based on a user's basic body information, their current body fat percentage can be calculated. However, because the human body can have localized areas of obesity, even at the same body fat percentage, the degree of obesity in the same area may vary between different people. For example... Figure 3 As shown, by setting multiple morphological images for a given body fat percentage, and using an image matching algorithm to match multiple morphological images corresponding to the same body fat percentage in the morphological image library, the current morphological image of a user's target area can be obtained. Furthermore, by setting a reasonable reference body fat percentage, the expected morphological image for the user's height, age, and gender can be obtained. The expected morphological image uses the morphological image corresponding to the standard model for each body fat percentage. For the same gender, age, and height, a standard morphological image can be preset at a given body fat percentage, which the user can select before undergoing fat reduction treatment. At this point, the morphological image library contains the morphological images corresponding to the aforementioned standard model.

[0044] In a practical application, the reference body fat percentage can be selected by the user. For example, some users require a body fat percentage below the normal range. In this case, control module 4 also acquires the user's selected expected body fat percentage and, based on the expected body fat percentage and basic body information, obtains the expected morphological image. By pre-setting standard morphological images corresponding to different body fat percentages, the system can obtain the corresponding expected morphological image when the user determines the desired body fat percentage. If the user does not select a reference body fat percentage, the system can use the median value of the normal body fat percentage as the reference body fat percentage.

[0045] Based on the user's basic body information and the requested expected body fat percentage, the difference between the user's current body fat percentage and the expected body fat percentage can be obtained, thus deriving the corresponding treatment parameters. The correspondence between the treatment parameters and the body fat percentage difference can be a preset one-to-one relationship. Different body fat percentage differences correspond to different first preset frequencies and first preset intensities of low-frequency magnetic fields, and different second preset frequencies and second preset intensities of mid-frequency magnetic fields. The preset relationship is not limited; for example, it can be based on a positive correlation, where the larger the body fat percentage difference, the higher the frequency and intensity can be.

[0046] In a practical application, such as Figure 3 As shown, for a target area, different application points yield different treatment effects. Generally, targeted fat reduction and body shaping are performed on the areas with the most obvious obesity. The control module 4 determines the location of the maximum deviation in the current shape image that exceeds the area of ​​the expected shape image based on the current shape image and the expected shape image. The application point covers the location of the maximum deviation. At this time, the control module 4 can also mark the location of the maximum deviation in the detection image to remind the operator so that the operator can focus on the location of the maximum deviation for fat reduction treatment.

[0047] like Figure 1 The weight loss device may further include a touch display module 5. This module generates basic body information of the user upon touch, and also generates a first activation signal and a second activation signal upon touch. The control module 4, triggered by the first activation signal, controls the low-frequency magnetic pulse generator 2 to operate, and triggered by the second activation signal, controls the medium-frequency magnetic pulse generator 3 to operate. The touch display module 5 can also display detection images, current morphology images, and expected morphology images. When the control module 4 marks the position of maximum deviation on the detection image, it can be displayed on the touch display module 5. The weight loss device can be operated via an app or operating system, using touch controls or other methods.

[0048] For example, the touch display module 5 can be a capacitive liquid crystal display screen, which can be touched by the operator. By touching a designated area, a first start signal and a second start signal can be generated, thereby controlling the start and stop of the low-frequency magnetic pulse generation module 2 and the medium-frequency magnetic pulse generation module 3.

[0049] For example, the touch display module 5 can also be used to display the operating status information of the magnetic pulse and surface acoustic wave fat reduction device. The operating status information includes the operating parameters, the first operating time of the low-frequency magnetic pulse generation module 2, and the second operating time of the medium-frequency magnetic pulse generation module 3.

[0050] The control module 4 is also used to obtain a first running time based on the duration of the first start signal and a second running time based on the duration of the second start signal. Thus, the user or operator can obtain the current treatment progress through the touch display module 5.

[0051] like Figure 1 As shown, this embodiment also provides a weight loss system, including an external terminal 7 and the aforementioned weight loss device. The weight loss device may include a communication module 6, which is used to communicate with the external terminal 7 and obtain control signals sent by the external terminal 7. The control module 4 of the weight loss device is used to obtain the control signals and, under the triggering of the control signals, control the low-frequency magnetic pulse generation module 2 of the weight loss device to work and / or control the medium-frequency magnetic pulse generation module 3 of the weight loss device to work. The control module 4 is also used to send the action parameters to the external terminal 7 through the communication module 6. The control module 4 is also used to obtain the user's basic body information sent by the external terminal 7 through the communication module 6.

[0052] like Figure 1 As shown, the weight loss device may further include a communication module 6, which is used to communicate with an external terminal 7 and acquire control signals sent by the external terminal 7. The control module 4 is also used to acquire control signals and, upon triggering the control signals, control the low-frequency magnetic pulse generator module 2 to operate and / or control the medium-frequency magnetic pulse generator module 3 to operate. The control signals may include a first start signal and a second start signal.

[0053] The control module 4 is also used to send the operating parameters to the external terminal 7 via the communication module 6. The control module 4 is also used to obtain the user's basic physical information sent by the external terminal 7 via the communication module 6.

[0054] Operators can send relevant user information (including but not limited to basic body information) to the fat reduction device via external terminals 7, such as mobile phones or computers. This information may include the user's expected body fat percentage, expected treatment cycle, or single treatment time. Users or operators can also obtain relevant treatment information, such as treatment parameters, and acquire detection images via external terminal 7, allowing users to assess the treatment effect. The fat reduction device can be controlled via an app using Bluetooth or Wi-Fi.

[0055] Example 2:

[0056] like Figures 4 to 6 As shown, this embodiment provides a low-frequency magnetic pulse generating module 2, which may include at least one first coil connector 22 and multiple first coils 21. The first coils 21 are detachably connected to the first coil connector 22, and the first coils 21 are electrically connected to the control module 4 through the first coil connector 22. The control module 4 may include a magnetic field control module 4, which is used to control the frequency, intensity, and timing of the magnetic field generated by the first coils 21 through the first coil connector 22. The frequency and intensity of the magnetic field generated by each first coil 21 are different, and the frequency and intensity of the magnetic field generated by all the first coils 21 cover a first preset frequency and a first preset intensity; and / or, the first preset frequency is 0-400Hz, and the first preset intensity is 0-8T.

[0057] Specifically, one coil of the low-frequency magnetic pulse generation module 2 can independently generate a first therapeutic magnetic field with a frequency of 0-50Hz and an intensity of 0-1T. Within the 0-50Hz range, the frequency of the first magnetic field follows a Gaussian distribution, and within the 0-1T range, the intensity of the first magnetic field also follows a Gaussian distribution. Another coil of the low-frequency magnetic pulse generation module 2 can independently generate a second therapeutic magnetic field with a frequency of 50-100Hz and an intensity of 1-2T. Within the 50-100Hz range, the frequency of the second magnetic field also follows a Gaussian distribution, and within the 1-2T range, the intensity of the second magnetic field also follows a Gaussian distribution. Finally, another coil of the low-frequency magnetic pulse generation module 2 can independently generate a third therapeutic magnetic field with a frequency of 100-150Hz and an intensity of 2-3T. Within the 100-150Hz range, the frequency of the third magnetic field also follows a Gaussian distribution, and within the 2-3T range, the intensity of the third magnetic field also follows a Gaussian distribution. One coil of the low-frequency magnetic pulse generation module 2 can independently generate a fourth therapeutic magnetic field with a frequency of 150-200Hz and an intensity of 3-4T. Within the 150-200Hz range, the frequency of the fourth magnetic field follows a Gaussian distribution, and within the 3-4T range, the intensity of the fourth magnetic field also follows a Gaussian distribution. Another coil of the low-frequency magnetic pulse generation module 2 can independently generate a sixth therapeutic magnetic field with a frequency of 250-300Hz and an intensity of 5-6T. Within the 250-300Hz range, the frequency of the sixth magnetic field follows a Gaussian distribution, and within the 5-6T range, the intensity of the sixth magnetic field also follows a Gaussian distribution. One coil of the low-frequency magnetic pulse generation module 2 can independently generate a seventh therapeutic magnetic field with a frequency of 300-350Hz and an intensity of 6-7T. Within the 300-350Hz range, the frequency of the seventh magnetic field follows a Gaussian distribution, and within the 6-7T range, the intensity of the seventh magnetic field also follows a Gaussian distribution. Another coil of the low-frequency magnetic pulse generation module 2 can independently generate an eighth therapeutic magnetic field with a frequency of 350-400Hz and an intensity of 7-8T. Within the 350-400Hz range, the frequency of the eighth magnetic field also follows a Gaussian distribution, and within the 7-8T range, the intensity of the eighth magnetic field also follows a Gaussian distribution. The two first coils 21 of the low-frequency magnetic pulse generation module 2 can be driven independently or in combination.

[0058] During the use of the aforementioned fat reduction device and fat reduction system, when selecting the first to eighth treatment magnetic fields of the low-frequency magnetic pulse generation module 2, one or more of them are selected in order from low to high according to the patient's urgency and willingness to lose weight and their physical tolerance. Only one first coil 21 can be placed in a weight loss area (corresponding to the target area).

[0059] The low-frequency magnetic pulse generating module 2 may include two first coil connectors 22 and multiple first coils 21 of different sizes. The first coil connectors 22 and the first coils 21 are connected by detachable snap-fit. The first coil connectors 22 are detachable and the first coils 21 are replaceable. Each first coil connector 22 is connected to the magnetic field generating drive module 42 through a separate special cable. It can be controlled and driven individually or the two first coil connectors 22 can be controlled and driven in conjunction. The effective diameter of a single first coil 21 can be 120mm, 100mm, 80mm, 60mm, or 30mm. The copper wire wound on the first coil 21 is 3mm square and has 30-60 turns.

[0060] The low-frequency magnetic pulse generator module 2 is positioned above the target area for fat reduction, such as the buttocks, legs, arms, waist, and abdomen, preferably 10mm-100mm away. It precisely generates a modulated alternating magnetic field in the area to be reduced and its adjacent areas, thereby inducing an alternating electric field in the area to be reduced and its adjacent areas. This alternating electric field can depolarize or hyperpolarize the nerve cells in the area to be reduced and its adjacent areas, inducing involuntary contraction and shaking of the muscles in the area to be reduced and its adjacent areas, consuming a large amount of energy. This can reduce the size and number of fat cells, exercise and shape the muscle tissue, open up the ion permeation channels in the fat tissue area, stimulate the ion permeability inside the fat tissue cells, and accelerate the consumption of fat tissue cells.

[0061] Example 3:

[0062] like Figures 6 to 8 As shown, the intermediate frequency magnetic pulse generating module 3 may include at least one second coil connector 32 and multiple second coils 31. The second coils 31 are detachably connected to the second coil connector 32, and the second coils 31 are electrically connected to the control module 4 through the second coil connector 32. The control module 4 may include a magnetic field control module 4, which is used to control the frequency, intensity, and timing of the magnetic field generated by the second coils 31 through the second coil connector 32. The frequency and intensity of the magnetic field generated by each second coil 31 are different, and the frequency and intensity of the magnetic field generated by all the second coils 31 cover a second preset frequency and a second preset intensity; and / or, the second preset frequency is 500KHz-1000KHz, and the second preset intensity is 0-5mT.

[0063] Specifically, one coil of the intermediate frequency magnetic pulse generation module 3 can independently generate a 9th therapeutic magnetic field with a frequency of 500-600 kHz and an intensity of 0-1 mT. Within the 500-600 kHz range, the frequency of the 9th magnetic field follows a random non-Gaussian distribution, and within the 0-1 mT range, the intensity of the 9th magnetic field follows a random non-Gaussian distribution. Another coil of the intermediate frequency magnetic pulse generation module 3 can independently generate a 10th therapeutic magnetic field with a frequency of 600-700 kHz and an intensity of 1-2 mT. Within the 600-700 kHz range, the frequency of the 10th magnetic field follows a random non-Gaussian distribution, and within the 1-2 mT range, the intensity of the 10th magnetic field follows a Gaussian distribution. One coil of the intermediate frequency magnetic pulse generation module 3 can independently generate an 11th therapeutic magnetic field with a frequency of 700-800 kHz and an intensity of 2-3 mT. Within the 700-800 kHz range, the frequency of the 11th magnetic field follows a random non-Gaussian distribution, and within the 2-3 mT range, the intensity of the 11th magnetic field also follows a random non-Gaussian distribution. Another coil of the intermediate frequency magnetic pulse generation module 3 can independently generate a 12th therapeutic magnetic field with a frequency of 800-900 kHz and an intensity of 3-4 mT. Within the 800-900 kHz range, the frequency of the 12th magnetic field also follows a random non-Gaussian distribution, and within the 3-4 mT range, the intensity of the 12th magnetic field also follows a random non-Gaussian distribution. One coil of the intermediate frequency magnetic pulse generation module 3 can independently generate a 13th therapeutic magnetic field with a frequency of 900-1000KHz and an intensity of 4-5mT. Within the range of 900-1000KHz, the frequency of the 13th magnetic field satisfies a random non-Gaussian distribution, and within the range of 4-5mT, the intensity of the 13th magnetic field satisfies a random non-Gaussian distribution. The two second coils 21 of the low frequency magnetic pulse generation module 2 can be driven independently or in combination.

[0064] During the use of the aforementioned fat reduction device and fat reduction system, when selecting the 9th to 13th therapeutic magnetic fields generated by the second coil 31 of the intermediate frequency magnetic pulse generation module 3, one or more of the therapeutic magnetic fields can be selected in order from low to high according to the patient's urgency and willingness to lose weight and their physical tolerance. Only one second coil 31 can be placed in one weight loss area.

[0065] The intermediate frequency magnetic pulse generating module 3 may include two second coil connectors 32 and multiple second coils 31 of different sizes. The second coil connectors 32 and the second coils 31 are connected by detachable snap-fit. The second coil connectors 32 are detachable and the second coils 31 are replaceable. One second coil connector 32 is connected to the magnetic field generating drive module 42 through a separate special cable. It can be controlled and driven independently, or the two second coil connectors 32 can be controlled and driven in conjunction. The effective diameter of a single second coil 31 is 100mm or 80mm. The copper wire wound on the second coil 31 is 3mm square and has 10-30 turns.

[0066] The mid-frequency magnetic pulse generator module 3 is positioned above the target area for fat reduction, such as the buttocks, legs, arms, waist, and abdomen, preferably 10mm-100mm in diameter. It precisely generates a modulated mid-frequency alternating magnetic field in the area to be reduced and adjacent areas, thereby inducing a mid-frequency alternating electric field in the area to be reduced and adjacent areas. The alternating electric field causes muscle cells in the area to be reduced and adjacent areas to contract at a higher frequency, resulting in a more aesthetically pleasing arrangement of muscle tissue and a better visual appearance. The mid-frequency magnetic pulse further improves the uniformity of the thermal effect of the magnetic field stimulation, which can reduce pain, promote the regeneration and remodeling of collagen and elastin fibers, improve skin elasticity and texture, tighten the skin, improve blood and lymph circulation, and improve the metabolism of local and / or adipose tissue.

[0067] Example 4:

[0068] like Figure 6 As shown, in the aforementioned fat reduction device and system, the control module 4 controls the operation of the fat reduction device, controls and drives the low-frequency magnetic pulse generating module 2 to generate a low-frequency therapeutic magnetic field according to a preset mode, controls and drives the medium-frequency magnetic pulse generating module 3 to generate a medium-frequency therapeutic magnetic field according to a preset mode, receives the detection image information acquired by the image acquisition module 1, and calculates the preferred driving and control modes of the low-frequency magnetic pulse generating module 2 and the medium-frequency magnetic pulse generating module 3. The control module 4 may include a magnetic field control module 41 and a magnetic field generation driving module 42.

[0069] like Figure 5 and Figure 8 As shown, in the fat reduction device and system, the magnetic field control module 41 may include a timing control module, an intensity control module, and a frequency control module to generate preset driving modes for a single coil or multiple coils. Different driving modes generate magnetic fields with different timings, frequencies, and intensities.

[0070] like Figure 5 As shown, in the fat reduction device and fat reduction system, the magnetic field generating drive module 42 generates a preset drive current for a single first coil 21 or multiple first coils 21 according to a preset drive mode, so as to drive the first coil 21 to generate a therapeutic magnetic field of preset frequency and intensity. The drive modes between the two coils of the low-frequency magnetic pulse generating module 2 can be the same or different.

[0071] like Figure 8As shown, in the fat reduction device and fat reduction system, the magnetic field generating drive module 42 generates a preset drive current for a single second coil 31 or multiple second coils 31 according to a preset drive mode, so as to drive the second coils 31 to generate a therapeutic magnetic field of preset frequency and intensity. The drive modes between the two coils of the intermediate frequency magnetic pulse generating module 3 can be the same or different.

[0072] In a practical application, such as Figure 9 As shown, the magnetic field control module 4 and the magnetic field generating drive module 42 can be configured as a PWM chip + push-pull structure drive circuit. The magnetic field control module 4 can use an integrated circuit SG3525 as the push-pull control circuit 43. The magnetic field generating drive module 42 can include a push-pull drive circuit 44, a transformer rectifier circuit 45, and a magnetic field generating main circuit 46. The push-pull drive circuit 44 is composed of transistors Q1-Q6. The transformer rectifier circuit 45 includes an isolation transformer and a high-voltage rectifier circuit. The isolation transformer Tr1 provides the second stage of reinforced insulation for the device. The magnetic field generating main circuit 46 can include a high-voltage energy storage capacitor C100 and a silicon controlled rectifier (SCR) 1. The magnetic field generating main circuit 46 is electrically connected to coil L1, which can be either a first coil 21 or a second coil 31.

[0073] like Figure 1 , Figure 5 , Figure 6 , Figure 8 and Figure 9 As shown, in the fat reduction device and system provided in this embodiment, the control module 4 may further include a processing module, which is responsible for the operation of the fat reduction device. In practical applications, the fat reduction device can obtain control signals through the touch display module 5, or it can receive input commands through physical buttons or knobs.

[0074] Specifically, the operator can input an intensity signal by adjusting a rotary switch. When the switch is turned on, a start signal is input to the processing module; when it is turned off, a stop signal is input. The processing module receives the input commands from the rotary switch, sets and stores the stimulation intensity, and outputs start / stop information. The operator can select the corresponding timing and frequency of the magnetic field, such as a sine wave or square wave, by pressing buttons. The processing module responds to the signal triggered by the buttons. Based on the intensity, frequency, and timing of the magnetic field selected by the operator, the processing module outputs the signals to the magnetic field control module 4. The magnetic field control module 4 then drives the coil to generate a magnetic field through the magnetic field generation drive module 42. Simultaneously, the fat reduction device can also be equipped with temperature and voltage sensors to obtain the coil's operating temperature and driving voltage, ensuring the coil operates only after the set voltage and other conditions are met. Using a physical rotary switch and button operation, manual operation is possible when image acquisition of the target area is impossible or treatment parameters cannot be obtained from the detected images.

[0075] In the aforementioned fat reduction device and system, the low-frequency magnetic pulse generation module 2 and the medium-frequency magnetic pulse generation module 3 are driven by independent cables. The treatment coils driven by the low-frequency magnetic pulse generation module 2 and the medium-frequency magnetic pulse generation module 3 cannot be used simultaneously on the same treatment site of the same patient, and must be used at different times.

[0076] like Figure 10 As shown, in the fat reduction device and system, the magnetic field generation drive module 42 generates a specific drive current for a single coil or multiple coils according to a specific drive mode, so as to drive the coil to generate a therapeutic magnetic field of a specific frequency and intensity. The modes between the two first coils 21 of the low-frequency magnetic pulse generation module 2 can be the same or different, and the modes between the two second coils 31 of the medium-frequency magnetic pulse generation module 3 can be the same or different.
