Description

Technical Field

[0001] The embodiments of the present disclosure relate to the field of medical device technology, and in particular to a flexible brace for spinal electrical stimulation. Background Art

[0002] The goal of scoliosis treatment is to correct the deformity and halt its progression, restoring the natural curvature of the spine. Scoliosis is a three-dimensional spinal deformity characterized by lateral curvature of one or more segments of the spine, possibly accompanied by vertebral rotation. There are many treatment options for scoliosis, including bracing, a conservative approach. Braces are currently categorized as either integral or segmental. Braces provide external support to halt or slow the progression of scoliosis.

[0003] However, when using the above brace, the following technical problems often occur:

[0004] First, most integral and segmented braces are 3D-printed products, with high material hardness, low comfort, and poor user experience. In addition, the braces need to be worn for a long time, and the harder material leads to low user compliance.

[0017] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: the spinal electrical stimulation flexible brace disclosed herein uses a flexible tight-fitting exoskeleton suit that fits the user's body curve, thereby improving user compliance. While exercising the strength of the paraspinal muscles through electrode patches, it can also allow users to have some understanding of their scoliosis conditions. Specifically, the reasons for the low user compliance, the failure to improve the strength of the user's paraspinal muscles, and the inability for users to have a clear understanding of their scoliosis conditions are that most of the integral and segmented braces are 3D printed products, with high material hardness, low comfort, and poor user experience. When worn for a long time, user compliance is low, especially for children and adolescents who need to correct deformities more, the compliance problem is even greater. When treating users, users cannot have any understanding of their scoliosis conditions. Users are passively treated, without subjective awareness to drive lifestyle adjustments, and are unable to exercise the strength of their paraspinal muscles. Based on this, the spinal electrical stimulation flexible brace disclosed in the present invention uses a flexible tight-fitting exoskeleton suit with a soft material that fits the user's body curve, thereby improving the user's compliance. The concave and convex paraspinal muscle areas of the user's scoliosis are exercised and relaxed through at least one partitioned electrical stimulation electrode patch on the back of the flexible tight-fitting exoskeleton suit. By adjusting the balance of the concave and convex paraspinal muscles, the purpose of adjusting scoliosis is achieved. At the same time, point electrical stimulation is performed through at least one top vertebra point stimulation electrode patch on the back of the flexible tight-fitting exoskeleton suit as a prompt function, so that the user has a correct understanding of his or her own scoliosis condition during use, and the user consciously pays attention to the posture and body posture in daily life. Therefore, the spinal electrical stimulation flexible brace disclosed in the present invention improves the user's compliance, and can achieve the purpose of adjusting scoliosis by adjusting the balance of the concave and convex paraspinal muscles. At the same time, it can also prompt the user's scoliosis position, so that the user has some understanding of his or her own scoliosis condition, and the subjective understanding drives the adjustment of lifestyle.

[0026] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Figure 1 Schematic diagram of the front structure of a flexible spinal electrical stimulation brace according to some embodiments of the present disclosure. Figure 1 It includes a flexible tight-fitting exoskeleton suit 1, a first positioning member 2, a second positioning member 3, a fixing member 4, and a control device 5.

[0028] Figure 2 Schematic diagram of the back structure of the spinal electrical stimulation flexible brace according to some embodiments of the present disclosure. Figure 2It includes a positioning line 6, an electrode patch 7 corresponding to the top of the concave side of the apical vertebra, an electrode patch 8 corresponding to the bottom of the concave side of the apical vertebra, an electrode patch 9 corresponding to the top of the convex side of the apical vertebra, an electrode patch 11 corresponding to the bottom of the convex side of the apical vertebra, and an apical vertebra point stimulation electrode patch 10.

[0029] In some embodiments, the above-mentioned spinal electrical stimulation flexible brace includes a flexible tight-fitting exoskeleton suit 1, at least one partitioned electrical stimulation electrode patch, at least one top vertebrae stimulation electrode patch, a positioning piece, a control device 5 and a fixing piece 4. The above-mentioned flexible tight-fitting exoskeleton suit 1 is worn on the torso of a user with spinal deformity. The above-mentioned flexible tight-fitting exoskeleton suit 1 can be a customized flexible tight-fitting vest that fits the torso of a user with spinal deformity. The above-mentioned flexible tight-fitting exoskeleton suit 1 can be divided into two layers, the outer layer can be made of a high-elasticity textile material, and the above-mentioned high-elasticity textile material can be made of a blend of spandex, nylon and polyester fibers, with high ductility, breathability and durability. The inner layer can be a cotton-spandex blend (such as spandex 5%-10% + cotton 95%-90%) to ensure softness and comfort and reduce skin friction. In practice, before making the above-mentioned flexible tight-fitting exoskeleton suit 1, the body circumference of the user with spinal deformity can be measured first. For example, the three measurements and scoliosis angle of a user with spinal deformity are measured, and the sizes of the inner and outer layers are cut out according to the measured data. Suture grooves for the at least one partitioned electrical stimulation electrode patch and the at least one apical vertebra stimulation electrode patch are reserved in the inner layer, and interface grooves for the corresponding connecting wires are reserved in the outer layer. The above-mentioned suture grooves can match the shapes of the at least one partitioned electrical stimulation electrode patch and the at least one apical vertebra stimulation electrode patch. The above-mentioned interface grooves can be circular holes that can pass through the connecting wires of the at least one partitioned electrical stimulation electrode patch and the at least one apical vertebra stimulation electrode patch. The suture groove area of the inner layer can be bonded to the electrode patch using hydrocolloid. The interface groove area of the outer layer can be sealed with silicone material to prevent friction and sweat penetration. The inner and outer layers can be sutured using elastic sutures (such as Lycra thread) to ensure ductility.

[0030] In some embodiments, at least one partitioned electrical stimulation electrode patch is disposed on the inner side of the back of the flexible tight-fitting exoskeleton suit 1 and distributed in the paraspinal muscle areas on the concave and convex sides of the scoliosis of the user with spinal deformity. The at least one partitioned electrical stimulation electrode patch may include a flexible base layer, a conductive layer, and an insulating isolation layer. The flexible base layer may be made of a polyurethane film, with a microporous array on the surface to enhance breathability. The conductive layer may be composed of a conductive carbon film, covering the surface of the base layer to form an electrode active area. The insulating isolation layer may be made of medical-grade TPU material, covering the non-working area of the conductive layer. The distribution area of the at least one partitioned electrical stimulation electrode patch on the inner side of the back inner layer of the flexible tight-fitting exoskeleton suit 1 can be determined based on the imaging data of the user with spinal deformity. The imaging data may be an image of the spinal bone structure of the user with spinal deformity obtained by an X-ray imaging device in a hospital. For example, a doctor uses an X-ray imaging device to obtain an image of the spinal bone structure of a user with spinal deformity, and determines the distribution area of the at least one partitioned electrical stimulation electrode patch around the scoliosis based on the spinal bone structure image, and marks it on the flexible tight-fitting exoskeleton suit 1 to facilitate the installation of the at least one partitioned electrical stimulation electrode patch. In addition, the at least one partitioned electrical stimulation electrode patch can be designed with a certain curvature according to the shape of the scoliosis to fit the concave and convex side paraspinal muscle areas of the scoliosis. After the at least one partitioned electrical stimulation electrode patch is activated, the concave side paraspinal muscle area of the user with spinal deformity can generate high-frequency, low-pulse width electrical stimulation (such as neuromuscular electrical stimulation (NMES)) through the electrode patch to activate the concave side paraspinal muscles, causing them to contract periodically, which can increase the volume and strength of the concave side paraspinal muscles. The paraspinal muscle area on the convex side of users with spinal deformity can generate low-frequency, wide-pulse electrical stimulation (such as transcutaneous electrical nerve stimulation (TENS)) through electrode patches to reduce the tension of the paraspinal muscles on the convex side, thereby achieving the purpose of relaxing the paraspinal muscles on the convex side. By electrically stimulating the paraspinal muscles at a certain frequency, the muscles can be relaxed or contracted rigidly, the paraspinal muscles on the convex side can be relaxed, and the paraspinal muscles on the concave side can be exercised. By adjusting the balance of the paraspinal muscles on the concave and convex sides, the purpose of regulating scoliosis can be achieved. For example, electrical stimulation treatment is performed three times a day, each time for 2 hours. At least one partitioned electrical stimulation electrode patch located on the concave side can be set to a frequency of 50Hz, a pulse width of 200μs, and a current intensity gradually increased from 30mA to 60mA, preferably with rigid muscle contraction, but avoiding pain, so as to achieve the effect of exercising the paraspinal muscles on the concave side. At least one partitioned electrical stimulation electrode patch located on the convex side can be set to a frequency of 4 Hz, a pulse width of 500 μs, and a current intensity of 30 mA, preferably with slight vibration to avoid tetanic contraction, so as to achieve the effect of relaxing the paraspinal muscles on the convex side.

[0031] In some embodiments, at least one apical vertebra stimulation electrode patch is positioned on the inner back side of the flexible, tight-fitting exoskeleton suit 1, at the projected location corresponding to the apical vertebra of scoliosis. The apical vertebra stimulation electrode patch 10 may include a flexible base layer, a conductive layer, and an insulating isolation layer. The flexible base layer may be made of a polyurethane film with a microporous array on its surface to enhance breathability. The conductive layer may be a conductive carbon film, covering the base layer to form an active electrode area. The insulating isolation layer may be made of medical-grade TPU material, covering the inactive area of the conductive layer. The body surface location corresponding to the apical vertebra of scoliosis can be determined based on the imaging data and marked on the back side of the flexible, tight-fitting exoskeleton suit 1 to facilitate installation of the at least one apical vertebra stimulation electrode patch. For example, a doctor can determine the body surface location corresponding to the apical vertebra based on the imaging data and mark it on the flexible, tight-fitting exoskeleton suit 1 to facilitate installation of the at least one apical vertebra stimulation electrode patch. When the user with spinal deformity activates the at least one zoned electrical stimulation electrode patch, the at least one apical vertebra stimulation electrode patch can also be activated simultaneously. The at least one top vertebrae stimulation electrode patch can serve as a reminder function through point electrical stimulation, for example, intermittent stimulation (once every 30 seconds, with a current intensity of 5 mA), to remind the user that this part is a scoliotic part during each exercise and daily life, so that the user can consciously pay attention to the posture and body posture in daily life.

[0032] In some embodiments, the positioning member is provided on the front of the flexible tight-fitting exoskeleton suit 1. The positioning member may be an arc-shaped soft silicone block. The positioning member is provided between the inner layer and the outer layer of the flexible tight-fitting exoskeleton suit 1, and may be located on the left chest and / or the right chest, or may be located at the navel. The positioning member can be used by the user to verify the wearing position when wearing the suit, so that the position of the electrode patch after wearing is more accurate, thereby increasing the therapeutic effect of electrical stimulation. The shape of the positioning member can be customized by the doctor based on the chest circumference data or navel shape of the user with spinal deformity, so as to better fit the body curve of the user with spinal deformity.

[0033] In some embodiments, the control device 5 is connected to the partitioned electrical stimulation electrode patch and the apex vertebra stimulation electrode patch 10 via a connecting line. The control device 5 is fixed to the flexible tight-fitting exoskeleton suit 1 via the fixing member 4. The control device 5 can control the start and stop of any partitioned electrical stimulation electrode patch and any apex vertebra stimulation electrode patch, and adjust parameters (such as duration, current intensity, frequency, pulse width), and can also control the start and stop of the operating mode. The operating modes may include but are not limited to relaxation mode, treatment mode, and do not disturb mode. The relaxation mode can be to relieve muscle tension or promote relaxation through low-intensity, low-frequency electrical stimulation. For example, the electrode patches of the concave and convex paraspinal muscle areas and the apex vertebra stimulation electrode patch 10 are all set to a frequency of 10 Hz, a pulse width of 1 ms, a current intensity of 5 mA, and a duration of 30 minutes, which are used to relax the concave and convex paraspinal muscle areas and relieve fatigue. The apex vertebra stimulation electrode patch 10 is used to prompt the user of the apex vertebra position, so that the user has a correct understanding of their own scoliosis condition. The above-mentioned treatment mode can be that the electrode patch in the concave paraspinal muscle area is stimulated by high-frequency, low-pulse width electricity to cause it to contract periodically to increase the volume and strength of the paraspinal muscles. The electrode patch in the convex paraspinal muscle area is stimulated by low-frequency, wide-pulse width electricity to promote the relaxation of the paraspinal muscles. By adjusting the balance of the concave and convex paraspinal muscles, the purpose of regulating scoliosis is achieved. For example, the electrode patch in the concave paraspinal muscle area can be set to a frequency of 50Hz, a pulse width of 200μs, and a current intensity gradually increased from 30mA to 60mA (preferably with muscle tetanic contraction, but avoiding pain) for 2 hours to achieve the effect of exercising the concave paraspinal muscles. The electrode patch in the convex paraspinal muscle area can be set to a frequency of 4Hz, a pulse width of 500μs, and a current intensity of 30mA (preferably with slight tremor to avoid tetanic contraction) for 2 hours to achieve the effect of relaxing the convex paraspinal muscles. The above-mentioned top vertebra point stimulation electrode patch 10 is set to a frequency of 10Hz, a pulse width of 1ms, a current intensity of 5mA, and a duration of 2 hours. It is used to prompt the user's top vertebra position so that the user can have a correct understanding of his or her own scoliosis condition. The above-mentioned do not disturb mode can be used to prohibit the activation of any electrode patch to reduce disturbance to the user. For example, when sleeping at night, in order to prevent the accidental activation of any electrode patch and affect the user's sleep, you can choose to activate the do not disturb mode, set eight hours or a custom duration, and prohibit the activation of any electrode patch. After starting the above-mentioned operating mode, you can close the activated operating mode in advance by selecting the operating mode again, or select another operating mode to overwrite the current operating mode. The above-mentioned fixing part 4 can be a ring-shaped structure. For example, it can be a waist belt. The above-mentioned fixing part 4 can be adjusted in tightness by Velcro. A mother Velcro is provided on the inner side of one end and a child Velcro is provided on the outer side of the other end. The child Velcro can be extended to the middle part of the above-mentioned fixing part 4 to ensure stable fit for different waist circumferences. The above-mentioned fixing part 4 can fix the above-mentioned control device 5 through a card slot.The slot can be a stepped groove structure, with the upper layer being a wide guide area to guide the horizontal insertion of the control device 5. The wide guide area can be a rectangular device with a width slightly larger than the outer shell of the control device 5 (for example, the outer shell size + 0.5mm), guiding the initial positioning of the control device 5. The lower layer uses elastic snaps to engage and lock with the bottom groove of the control device 5, combined with an asymmetric structure to prevent misinsertion. The asymmetric structure can be designed with a raised edge on one side of the outer shell of the control device 5, and a limiting notch at the corresponding position of the slot to prevent reverse insertion.

[0034] Optionally, the at least one partitioned electrical stimulation electrode patch may include: an electrode patch 7 corresponding to the upper side of the concave side of the apical vertebra, an electrode patch 8 corresponding to the lower side of the concave side of the apical vertebra, an electrode patch 9 corresponding to the upper side of the convex side of the apical vertebra, and an electrode patch 11 corresponding to the lower side of the convex side of the apical vertebra. The distribution positions and shapes of the electrode patch 7 corresponding to the upper side of the concave side of the apical vertebra, the electrode patch 8 corresponding to the lower side of the concave side of the apical vertebra, the electrode patch 9 corresponding to the upper side of the convex side of the apical vertebra, and the electrode patch 11 corresponding to the lower side of the convex side of the apical vertebra can all be determined by the doctor based on the imaging data.

[0035] Optionally, a positioning line 6 is provided on the back of the flexible tight-fitting exoskeleton suit 1. This positioning line 6 may be a reflective strip. Based on the spinal morphology of a user with spinal deformity, this positioning line 6 may be attached to a body surface projection area on the back of the flexible tight-fitting exoskeleton suit 1 to observe the user's scoliosis. The body surface projection area represents the location on the back of the flexible tight-fitting exoskeleton suit 1 where the spinal morphology of the user with spinal deformity is mapped.

[0036] Optionally, the at least one partitioned electrical stimulation electrode patch and the at least one apical vertebrae stimulation electrode patch can both be flexible patches. The at least one partitioned electrical stimulation electrode patch and the at least one apical vertebrae stimulation electrode patch are both adhesively connected to the flexible tight-fitting exoskeleton suit 1. The flexible patch may include an upper flexible base layer, a conductive layer, and an insulating isolation layer. The flexible base layer may be made of a polyurethane film, and a microporous array is provided on the surface to enhance air permeability. The conductive layer may be composed of a conductive carbon film, which covers the surface of the base layer and is used to form an electrode active area. The insulating isolation layer may be made of medical-grade TPU material, covering the non-working area of the conductive layer.

[0037] Optionally, the positioning member may include a first positioning member 2 and a second positioning member 3. The first positioning member 2 may be located on the left chest of the flexible tight-fitting exoskeleton suit 1. For example, it may correspond to the nipple position of the left chest. The second positioning member 3 may be located on the right chest of the flexible tight-fitting exoskeleton suit 1. For example, it may correspond to the nipple position of the right chest. The first positioning member 2 and the second positioning member 3 may be arc-shaped silicone blocks, which may reduce the local sense of pressure and enhance the wearing comfort of the flexible tight-fitting exoskeleton suit 1. The first positioning member 2 and the second positioning member 3 are bonded to the flexible tight-fitting exoskeleton suit 1. For example, the bonding connection may be performed by bonding the positioning member 2 between the outer layer and the inner layer using medical glue.

[0038] Optionally, the flexible tight-fitting exoskeleton suit 1 may include individual compression fabric slices corresponding to the body trunk. The flexible tight-fitting exoskeleton suit 1 is manufactured by dividing the trunk into a plurality of functionalized compression fabric slices. For example, it is divided into the waist and back, abdomen, chest and side waist regions. The outer layer of the waist and back region uses high elastic fiber, and the inner layer uses a high spandex ratio blend, which can provide a certain gradient pressure (such as 20-30 mmHg) to assist in spinal stability. The outer layer of the side waist region is embedded with a breathable mesh structure, and the inner layer increases the cotton content (such as increased to 80%), taking into account free stretching and sweat extraction. The abdomen and chest regions use a low-compression cotton-spandex blend to ensure a soft touch. The production of the flexible tight-fitting exoskeleton suit 1 utilizes the elasticity of the material and the structural design to maintain the comfort of wearing and freedom of movement.

[0039] Optionally, the fixing member 4 may include an elastic waistband. The elastic waistband is designed to be worn around the user's waist. The elastic waistband may be made of a highly elastic blended fabric (e.g., 80% polyester + 20% spandex) with anti-slip silicone stripes on the inside and a high-density nylon outer layer for enhanced wear resistance and waterproofing.

[0040] Optionally, the control device 5 may include a circuit board, a battery compartment, and a remote control. The circuit board may include a communication unit, a controller, a power management unit, and a cable interface. The communication unit is communicatively connected to the remote control and is configured to receive control signals from the remote control. The communication unit may receive control signals (e.g., a 2.4 GHz carrier signal) transmitted by the remote control via a radio frequency receiving module. The radio frequency receiving module may include an nRF52832 chip and a 2.4 GHz microstrip antenna. For example, the control signals may include, but are not limited to, the operating mode, the current intensity, pulse width, and duration of any partitioned electrical stimulation electrode patch or any vertex point stimulation electrode patch. The controller may include a microcontroller chip and a patch driver circuit. The microcontroller chip may be an STM32F4 (with integrated ADC, DAC, and PWM modules), configured to process control signals received by the radio frequency receiving module and transmit the processed control signals to the patch driver circuit. The patch driver circuit may include an H-bridge driver chip (e.g., a DRV2605). The patch driver circuit may drive the corresponding electrode patch to operate according to the processed control signals transmitted by the microcontroller chip. Specifically, the RF receiving module can transmit the original control signal to the microcontroller chip via the SPI interface. The microcontroller chip can process the control signal and send the processed control signal to the patch drive circuit. The patch drive circuit drives the corresponding electrode patch to operate. The power management unit can include a dedicated chip and a charging chip. The dedicated chip can generate a pulse current to control the current intensity of the electrode patch. For example, the dedicated chip can be MAX1945. The charging chip is used to manage battery charging and discharging and can support 5V / 2A fast charging. For example, the charging chip can be TIBQ25601. The remote control can be made of ABS plastic with an anti-slip coating sprayed on the surface and contain multiple physical buttons. The remote control can send control signals (such as a 2.4GHz carrier signal) via a RF transmitter module. The RF transmitter module can include an nRF52832 chip and a 2.4GHz microstrip antenna. The nRF52832 chip of the RF transmitting module of the above-mentioned remote control is used to generate a control signal for the function corresponding to the physical button pressed by the user, and send the control signal to the RF receiving module of the above-mentioned communication unit through the microstrip antenna of the above-mentioned RF transmitting module to realize the transmission of the control signal. The functions of the multiple physical buttons of the above-mentioned remote control may include but are not limited to adjusting the current intensity (such as 1-12 gears, each gear can be set with a difference of 5mA), selecting an operating mode (such as treatment mode, relaxation mode and do not disturb mode), and setting a countdown (such as 10-60 minutes). The above-mentioned connection interface can be a GPIO pin, which is used for signal transmission between the above-mentioned control device 5 and the electrode patch. The above-mentioned battery box is detachably connected to the above-mentioned circuit board, and the above-mentioned battery box is electrically connected to the above-mentioned power management unit.The battery box can be a plastic shell (PC+ABS alloy) with spring contacts (2mm stroke) and anti-reverse polarity bosses inside the shell, suitable for 18650 lithium-ion batteries. The positive and negative poles of the battery box can use spring pins (2mm stroke, lifespan >100,000 times), which are connected to the positive and negative poles of the circuit board by squeezing the spring pins to achieve a detachable connection. The power management unit can include a charging port. For example, the charging port can be a USB-C port (supporting the PD protocol) with an input voltage of 5-20V and a maximum charging current of 2A. The remote control is placed in the remote control storage cavity of the control device 5, which is provided in the housing of the control device 5. The remote control storage cavity can be a dedicated space reserved in the housing of the control device 5 for storing the remote control. The inner side of the housing of the control device 5 is grooved, the size of which is adapted to the shape of the remote control, and the inner wall is affixed with a silicone anti-slip pad. The remote control storage cavity can secure the remote control by magnetic attraction, reducing the risk of the remote control falling out of the remote control storage cavity. For example, neodymium iron boron magnets (such as 4mm diameter, 1mm thickness, N52 grade) are embedded in the four corners of the remote control, and magnetic conductive sheets (such as Permalloy) are buried in the corresponding positions of the remote control storage cavity to reduce the risk of the remote control falling from the remote control storage cavity through magnetic attraction.

[0041] Furthermore, in the process of adopting a technical solution to solve the technical problems mentioned in the background art, the inventor discovered that when the above-mentioned spinal electrical stimulation flexible brace is activated, point electrical stimulation can be performed as a prompt function through at least one top vertebrae point stimulation electrode patch, so that the user can have a correct understanding of their own scoliosis during use and pay attention to adjusting their posture. However, when the above-mentioned spinal electrical stimulation flexible brace is not activated, it cannot prompt the user whether the posture is correct. In order to enable the user to pay attention to whether his posture is correct even when the spinal electrical stimulation flexible brace is not activated, combined with the technology owned by the inventor's unit, it can be decided to adopt the following solution.

[0042] Optionally, the apical vertebra stimulation electrode patch 10 in the at least one apical vertebra stimulation electrode patch may include a vibration device and a pressure sensor. The vibration device may be a linear resonant actuator (LRA). The pressure sensor may be a piezoresistive sensor (e.g., FlexiForce A201). The vibration device includes a vibration source and a drive circuit. The vibration source may include a mass block and an electromagnetic coil. The mass block may be a ferromagnetic alloy, configured to achieve linear reciprocating motion in an alternating magnetic field, thereby achieving a vibration effect. The electromagnetic coil drives the mass block to linearly reciprocate using alternating current, generating vertical vibration. The alternating current may be generated by the drive circuit. The drive circuit may include an H-bridge driver chip, such as the DRV2605, configured to receive control signals processed by the controller and output alternating current to drive the vibration source to generate vibration. The vibration source is fixed to the edge of the apical vertebra stimulation electrode patch 10 via a support structure and perpendicular to the skin surface. The support structure can be a cantilever beam, with one end fixed to the edge of the electrode patch and the other end connected to the vibration source, allowing the vibration source to vibrate vertically. Furthermore, high-damping silicone particles can be embedded within the support structure to absorb lateral vibration energy and ensure that the vibration direction is perpendicular to the skin surface. A hemispherical vibration focusing head can be provided at the end of the support structure. For example, the hemispherical vibration focusing head can have a diameter of 5 mm and be made of stainless steel for enhanced durability. The hemispherical vibration focusing head can concentrate the vibration energy and transmit it to the skin surface. The surface of the hemispherical vibration focusing head is covered with a silicone cushion (0.5 mm thick) to distribute contact pressure and prevent localized skin damage. The drive circuit is embedded in the control device 5 and is in communication with the control device 5. The vibration source is in communication with the drive circuit. The pressure sensor is embedded in the apical vertebra stimulation electrode patch 10 and is configured to detect pressure data at the apical vertebra. The pressure sensor is located in the central non-conductive area of the apical vertebra stimulation electrode patch 10, covering the apical vertebra area, and detects vertical pressure in the apical vertebra area. The pressure sensor is communicatively connected to the control device 5 .

[0043] Optionally, the circuit board of the control device 5 may further include a timer and a memory. The timer is configured to execute a set countdown task. For example, if the user sets the relaxation mode to run for 30 minutes via the control device 5, the timer will execute the 30-minute countdown task and stop the relaxation mode after the countdown task ends. The memory is configured to store preset threshold information, preset pressure threshold, user parameter information, and countdown task information. The preset threshold information may be a customized, pre-set range of parameters such as current intensity, frequency, pulse width, and duration, used for safety verification. For example, a doctor may first perform electrical stimulation on the user's paraspinal muscle area at a certain current intensity, analyze the current stimulation intensity to determine the current intensity range that the user can adapt to, and thus set the preset threshold information in a targeted manner. The preset threshold information may include threshold range information corresponding to each scoliosis area. For example, the preset threshold information may include, but is not limited to, threshold range information corresponding to the apical vertebra area, threshold range information corresponding to the concave side of scoliosis, and threshold range information corresponding to the convex side of scoliosis. For example, the threshold range information corresponding to the apical vertebra area can be: current intensity <10mA, frequency <20Hz, pulse width >500μs, and single duration does not exceed 2 hours. The threshold range information corresponding to the concave side of scoliosis can be: current intensity <70mA, frequency <60Hz, pulse width >100μs, and single duration does not exceed 2 hours. The threshold range information corresponding to the convex side of scoliosis can be: current intensity <50mA, frequency <50Hz, pulse width >200μs, and single duration does not exceed 2 hours, and the frequency of the vibration device is less than 200Hz. The above-mentioned preset pressure threshold can be a pre-set pressure parameter for safety verification. For example, the above-mentioned preset pressure threshold can be set to 50N. The above-mentioned user parameter information can be a parameter set by the user through the above-mentioned control device 5. For example, the above-mentioned user parameter information can include the operating time (such as 60 minutes), current intensity (such as 10mA), frequency (such as 10Hz), and pulse width (such as 500μs) of any partitioned electrical stimulation electrode patch or any apical vertebra point stimulation electrode patch. The countdown task information may include a user-defined runtime (e.g., 60 minutes) and a preset countdown (e.g., 30 minutes). For example, after the user starts any electrode patch, if the user does not select a runtime, the countdown task is the preset countdown (e.g., 30 minutes). If the user selects a custom runtime (e.g., 60 minutes), the countdown task is the user-defined runtime (e.g., 60 minutes). The controller is configured to perform the following steps:

[0044] The first step is to obtain the control signal of the remote controller through the communication unit, wherein the communication unit can transmit the control signal through the SPI interface.

[0045] The second step is to parse the control signal to obtain parsed information. The parsed information includes target electrode patch information and operation information. The control signal can be transmitted in a fixed format (e.g., synchronization header + target ID + operation type + parameter information + CRC checksum). The target ID can be the target electrode patch ID (e.g., electrode patch 7 corresponding to the upper concave side of the apical vertebra). The operation type can indicate the type of operation corresponding to the control signal. For example, operation types may include, but are not limited to, "adjust current intensity" and "start treatment mode." The parameter information can be the operation-related parameters corresponding to the control signal. For example, parameter information may include, but is not limited to: current intensity 10mA, frequency 10Hz, pulse width 500μs, and operation duration 10 minutes. In practice, first, the synchronization header of the control signal can be verified to be a preset synchronization header (e.g., 0xAAAA). Then, the target ID, operation type, and parameter information can be separated from the control signal as parsed information. Finally, the data integrity of the CRC checksum included in the control signal can be verified. Specifically, the number of bits in the CRC checksum can be determined to be a preset number of bits. For example, the preset number of bits can be 16 bits. The target electrode patch information may include the target ID. The operation information may include the operation type and the parameter information.

[0046] The third step is to perform security verification on the above-mentioned parsed information based on the preset threshold information to obtain the first verification information. In practice, the above-mentioned controller can first obtain parameter information from the parsed information. Then, determine the scoliosis area corresponding to the target electrode patch information included in the above-mentioned parsed information. Next, compare the obtained parameter information with the threshold range information corresponding to the above-mentioned scoliosis area in the above-mentioned preset threshold information to obtain the first verification information. Specifically, in response to determining that each parameter in the above-mentioned parameter information is within the range corresponding to the above-mentioned threshold range information, the information representing that the security verification has been passed can be determined as the first verification information. In response to determining that any parameter in the above-mentioned parameter information is not within the range corresponding to the above-mentioned threshold range information, the information representing that the security verification has not been passed can be determined as the first verification information. For example, the information representing that the security verification has been passed can be "passed". The information representing that the security verification has not been passed can be "failed".

[0047] In the fourth step, in response to the above-mentioned first verification information characterization being passed, the above-mentioned parsed information is converted into a control signal corresponding to the target electrode patch corresponding to the above-mentioned target electrode patch information, and the target electrode patch control signal and the first timing task information are obtained. In practice, the current intensity, frequency and pulse width included in the above-mentioned parsed information can be standardized first. For example, the current intensity is mapped to the digital register value of the DAC module (such as the digital register value corresponding to the current intensity of 10mA can be 0x0A), and the frequency and pulse width are calculated as the period of the timer (such as the period corresponding to the frequency of 10Hz can be 100ms) and the duty cycle (such as the duty cycle corresponding to the pulse width of 500μs can be 5%). Then, the connection line interface corresponding to the above-mentioned target electrode patch information is matched through the pre-stored configuration table. The connection line interface corresponding to the target electrode patch can be the interface of the connection line connected to the electrode patch in the patch drive circuit. The above-mentioned pre-stored configuration table can be a correspondence table between the electrode patch and the corresponding connection line interface. The above-mentioned pre-stored configuration table can include the ID of each group of electrode patches and the unique number of the corresponding connection line interface. For example, the connection line interface corresponding to the "electrode patch 7 above the concave side of the corresponding top vertebra" can be "interface 3", and the connection line interface corresponding to the "electrode patch 9 above the convex side of the corresponding top vertebra" can be "interface 4". Then, the standardized current intensity is converted into an analog voltage signal through the DAC module, and a constant current can be output to the connection line interface corresponding to the target electrode patch through the above-mentioned power management unit, and a square wave signal corresponding to the standardized frequency and pulse width is generated through the PWM module. Secondly, the above-mentioned analog voltage signal and the above-mentioned square wave signal can be determined as the target electrode patch control signal. At the same time, the countdown task is set according to the running time included in the above-mentioned analysis information to obtain the first timing task information. For example, the above-mentioned first timing task information includes a preset countdown (such as 30 minutes) or a user-defined running time (such as 20 minutes).

[0048] Step 5: Based on the target electrode patch control signal, the target electrode patch is driven to perform the operation corresponding to the operation information. In practice, the controller can drive the target electrode patch to perform the operation via the patch drive circuit. For example, the target electrode patch driven by the patch drive circuit is "electrode patch 7 corresponding to the upper side of the concave side of the top vertebra," and the operation to be performed is to set the current intensity to "10mA", the frequency to "10Hz", the pulse width to "500μs", and the operation duration to "20 minutes."

[0049] Step 6: In response to the completion of the first timing task corresponding to the first timing task information, a first shutdown signal is generated. The first timing task can be a running time set by the user, for example, 20 minutes. The first shutdown signal can be a low-level signal (such as 0V).

[0050] Step 7: Based on the first shutdown signal, the target electrode patch is controlled to stop operating. The patch driving circuit turns off all switches to reduce the current intensity of the target electrode patch to 0 mA.

[0051] In step 8, in response to determining that any subarea electrical stimulation electrode patch, any vertex point stimulation electrode patch, and the vibration device are not activated, the following steps are performed:

[0052] The first sub-step is to obtain pressure data from the pressure sensor. For example, the pressure data output by the pressure sensor (e.g., a differential input channel) can be acquired using the ADC module of an STM32. The pressure data can be serialized information acquired continuously in chronological order (e.g., 10 times per second at 10 Hz), with each data point associated with a timestamp.

[0053] In the second sub-step, the pressure data is filtered to obtain enhanced data. The controller may first low-pass filter the pressure data using an IIR filter (e.g., Butterworth, with a cutoff frequency of 10 Hz) to eliminate high-frequency noise (>10 Hz). The filtered data is then interpolated (e.g., linear interpolation) to improve the resolution and obtain enhanced data. The enhanced data may be pressure data that has been filtered to eliminate high-frequency noise and interpolated.

[0054] In the third sub-step, the enhanced data is subjected to pressure safety verification based on a preset pressure threshold to obtain second verification information. In practice, if the enhanced data is determined to be greater than the preset pressure threshold, the preset information indicating a pass can be determined as the second verification information. If the enhanced data is determined to be less than or equal to the preset pressure threshold, the preset information indicating a failure can be determined as the second verification information. For example, the preset pressure threshold can be 50N.

[0055] The fourth sub-step is to generate a vibration device control signal and a second timing task information in response to the above-mentioned second verification information being characterized as passed. In practice, the above-mentioned controller may first determine the ID and vibration parameters of the vibration device. The vibration parameters may include vibration frequency and vibration duration. The above-mentioned vibration frequency and vibration duration may be pre-set in the above-mentioned memory. For example, the vibration frequency is 150Hz and the vibration duration is 10 seconds. Then, the corresponding connection line interface may be matched through a preset vibration device configuration table. The above-mentioned preset vibration device configuration table may be a correspondence table between the vibration device and the corresponding connection line interface. The above-mentioned preset vibration device configuration table may include the ID of each group of vibration devices and the unique number of the corresponding connection line interface. Then, a PWM signal of the corresponding vibration frequency is generated as a vibration device control signal through the PWM module. At the same time, the countdown task is set according to the above-mentioned vibration duration to obtain the second timing task information.

[0056] The fifth sub-step is to drive the vibration device to perform a vibration operation based on the vibration device control signal. In practice, the controller can drive the vibration device to generate vibrations according to the vibration device control signal via the drive circuit. For example, the vibration device can generate vibrations with a frequency of 150 Hz and a duration of 10 seconds. The vibration generated by the vibration device reminds the user to adjust their posture even when not undergoing treatment to prevent worsening of scoliosis.

[0057] In a sixth sub-step, in response to the second timing task corresponding to the second timing task information ending, generating a second shutdown signal. The second timing task may be a preset running time, for example, 10 seconds. The second shutdown signal may be a low-level signal (e.g., 0V).

[0058] In the seventh sub-step, based on the second shutdown signal, the vibration device is controlled to stop operating. The driving circuit disconnects all switches, reducing the current intensity of the vibration device to 0 mA, and the vibration device stops operating.

[0059] The above optional embodiment, as an inventive point of the embodiment of the present disclosure, solves the technical problem that "when the traditional electrical stimulation brace is not activated, the user cannot notice whether his posture is correct, which may cause excessive force on the apical vertebra, reducing the therapeutic effect of scoliosis." The factors that lead to reduced therapeutic effect of scoliosis are often as follows: when the traditional electrical stimulation brace is not activated, the user cannot notice whether his posture is correct, which may cause excessive force on the apical vertebra, reducing the therapeutic effect of scoliosis. If the above factors are solved, the effect of electrical stimulation treatment can be improved. In order to achieve this effect, the present disclosure embeds a vibration device and a pressure sensor in the electrode patch at the apical vertebra. When any electrode patch and vibration device are not activated, the pressure sensor detects the force condition at the apical vertebra. If the pressure at the apical vertebra exceeds the preset pressure threshold, the vibration device will be activated to remind the user to pay attention to adjust his posture, which helps to improve the therapeutic effect of scoliosis.

[0060] The above-mentioned various embodiments of the present disclosure have the following beneficial effects: the spinal electrical stimulation flexible brace disclosed herein uses a flexible tight-fitting exoskeleton suit 1, which fits the user's body curve, improves the user's compliance, and while exercising the strength of the paravertebral muscles through the electrode patches, it can also allow the user to have some understanding of the scoliosis condition. Specifically, the reasons for the low user compliance, the failure to improve the strength of the user's paravertebral muscles, and the inability to allow the user to have a clear understanding of their scoliosis condition are: most of the integral and segmented braces are 3D printed products, with high material hardness, low comfort, and poor user experience. When worn for a long time, the user compliance is low, especially for children and adolescents who need to correct deformities more, the compliance problem is even greater. When treating the user, the user cannot be made aware of his or her scoliosis condition. The user is treated passively, without subjective awareness to drive lifestyle adjustments, and is unable to exercise the strength of the paravertebral muscles. Based on this, the spinal electrical stimulation flexible brace disclosed herein uses a flexible tight-fitting exoskeleton suit 1, which is made of soft material and fits the user's body curve, thereby improving the user's compliance. The strength of the user's paraspinal muscles is exercised through at least one partitioned electrical stimulation electrode patch on the back of the flexible tight-fitting exoskeleton suit 1. At the same time, point electrical stimulation is performed as a prompt function through at least one top vertebra point stimulation electrode patch on the back of the flexible tight-fitting exoskeleton suit 1, so that the user can have a correct understanding of his or her own scoliosis during use, and the user can consciously pay attention to the posture and body posture in daily life. Therefore, the spinal electrical stimulation flexible brace disclosed herein improves the user's compliance, and can achieve the purpose of adjusting scoliosis by adjusting the balance of the concave and convex side paraspinal muscles. At the same time, it can also prompt the user's scoliosis position, so that the user can have some understanding of his or her own scoliosis, and the adjustment of lifestyle is driven by subjective understanding.
