Description

Technical Field

[0001] This invention belongs to the field of medical device and rehabilitation engineering technology, specifically relating to a portable low-frequency magnetic stimulation rehabilitation device for pelvic floor muscles. Background Technology

[0002] The pelvic floor muscle low-frequency magnetic stimulation rehabilitation device is a new type of pelvic floor function rehabilitation treatment device. Its core working principle is to use an external pulsed magnetic field to penetrate the soft tissue and bones of the human body, and induce a weak current in the target neuromuscular tissue. Without invading human tissue, it can non-invasively activate the sacral nerve that controls pelvic floor function, and at the same time mobilize the deep and superficial pelvic floor muscle groups to achieve precise control of the passive contraction and passive relaxation state of the pelvic floor muscles, ultimately achieving the therapeutic effect of improving pelvic floor function. This type of device is currently mainly used to treat various pelvic floor dysfunction diseases such as urinary incontinence, pelvic organ prolapse, pelvic floor pain, and sexual dysfunction.

[0003] Currently, most pelvic floor muscle rehabilitation devices used in clinical practice suffer from excessive size and weight, hindering their mobility and making them inconvenient to carry. These devices are typically confined to treatment rooms in medical institutions. This means patients requiring pelvic floor rehabilitation must schedule appointments and travel to the hospital for each treatment, preventing them from conducting rehabilitation exercises at home. Frequent hospital visits not only consume significant personal time but also increase the burden on patients in terms of time and transportation. Furthermore, long-term treatment can easily lead to patient resistance and poor adherence, making these existing devices unsuitable for home use based on individual rehabilitation needs. To address this industry pain point and resolve the aforementioned issues with existing devices, we propose developing a portable low-frequency magnetic stimulation rehabilitation device for pelvic floor muscles. Summary of the Invention

[0004] The purpose of this invention is to provide a portable low-frequency magnetic stimulation rehabilitation device for pelvic floor muscles to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a portable pelvic floor muscle low-frequency magnetic stimulation rehabilitation device, comprising a carrying case, a cushion installed inside the carrying case, and a magnetic stimulation head module located at the center of the bottom of the cushion. The carrying case is externally connected to a controller, which includes a control switch, indicator lights, a PLC main control board, and a Bluetooth module. The cushion is installed at the top of the carrying case, and a receiving box is located at the bottom of the cushion. The receiving box contains the magnetic stimulation head module, which includes a magnetic core, an excitation coil, and a magnetic shielding layer. The magnetic shielding layer covers the magnetic core and the excitation coil, and the excitation coil is evenly wound around the outer periphery of the magnetic core. The receiving box also contains a low-frequency pulse magnetic field generating unit and an NTC thermistor. An embedded electromyography (EMG) signal acquisition unit is mounted on the top of the receiving box. A rechargeable lithium battery pack is located on one side of the carrying case. The embedded EMG signal acquisition unit includes surface electrode pairs and a preamplifier. The rechargeable lithium battery pack is connected to a power management unit.

[0006] Preferably, the portable case includes a handle, an anti-slip silicone pad, a first electromagnetic plate, a lid, a second electromagnetic plate, a recess, and a support column. One end of the support column is fixed to both sides of the middle of the interior of the portable case, and the other end supports the seat. The seat is embedded in the recess. The handle is fixedly installed on the middle of one side of the exterior of the portable case. The anti-slip silicone pad is fixed to the bottom of the portable case. The lid connects to the top of one side of the portable case, making the overall structure of the portable case stable, the handle convenient to carry, the anti-slip silicone pad ensuring stable placement of the device, the support column providing reliable support for the seat, and the seat embedded in the recess to prevent displacement.

[0007] Preferably, the first electromagnetic plate is fixedly embedded around the top of the portable case, and the second electromagnetic plate is fixedly embedded around the bottom outer periphery of the case lid. The positions of the first and second electromagnetic plates are corresponding, and the case lid is tightly closed by mutual attraction of the electromagnetic plates, preventing accidental opening during carrying or storage, and enhancing the sealing and portability of the device.

[0008] Preferably, the anti-slip silicone pad is fixedly attached to the bottom outer surface of the portable case to increase the friction between the device and the placement surface, prevent slippage, and ensure that the device will not slide back and forth or left and right when in use, especially when pressure is applied on the seat cushion, thereby improving the safety and comfort of use.

[0009] Preferably, the low-frequency pulse magnetic field generating unit is electrically connected to the excitation coil of the magnetic stimulation head module and the PLC main control board of the controller, respectively, and is used to generate a low-frequency pulse excitation signal of a set frequency. The unit generates a pulse current of a specific frequency and intensity according to the instructions of the PLC main control board, drives the excitation coil to generate a magnetic field, and realizes precise magnetic stimulation treatment for the pelvic floor muscles.

[0010] Preferably, the NTC thermistor is embedded inside the memory foam of the cushion and electrically connected to the PLC main control board. It is used to collect temperature data of the working area of ​​the device in real time. When the temperature exceeds the preset safety threshold, the PLC main control board automatically reduces or stops the magnetic stimulation output through control commands to prevent harm to the user due to overheating and ensure the safety and reliability of the treatment process.

[0011] Preferably, the embedded electromyography (EMG) signal acquisition unit acquires the user's pelvic floor muscle EMG signals through surface electrodes, amplifies them by a preamplifier, and transmits them to the PLC main control board. These EMG signals are used to assess the real-time activity status of the pelvic floor muscles, provide a basis for adjusting treatment parameters, realize closed-loop feedback therapy, and improve rehabilitation effects.

[0012] Preferably, the Bluetooth module is electrically connected to the PLC main control board, transmitting the collected electromyographic signals and treatment parameters to an external smart terminal device. Users or doctors can view treatment data and historical records through mobile APP and other terminals, and remotely adjust treatment plans, improving the convenience and intelligence of use.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. By specially setting up a support column and sink structure inside the portable case, combined with a customized seat cushion embedding installation method, and additionally designing a handle for easy gripping and movement, as well as an anti-slip silicone pad to increase contact friction, the entire pelvic floor rehabilitation device is not only structurally stable, but also easy to lift and move, and not easy to slip or tip over when placed. This greatly improves the overall portability and safety of daily use of the device, and directly solves the problem of the large size and inconvenience of moving and transporting traditional pelvic floor rehabilitation devices from the structural design level.

[0014] 2. By using the first electromagnetic plate and the second electromagnetic plate respectively set on the portable case and the case lid, the magnetic attraction between the two plates works together to achieve a tight closed connection between the case lid and the case. This effectively prevents the case lid from accidentally opening during the transport or storage of the device, further enhancing the overall airtightness of the portable case. This provides better protection for the various precision electronic and structural components placed inside the case, and significantly improves the overall reliability of the device during use and storage.

[0015] 3. Through the coordinated operation of multiple functional modules, including the low-frequency pulse magnetic field generator, PLC main control board, Bluetooth module, embedded electromyography signal acquisition unit, and NTC thermistor, the device successfully achieves closed-loop feedback therapy based on real-time electromyography signal acquisition and analysis of pelvic floor muscles. It can dynamically adjust various treatment parameters according to the patient's current muscle state. At the same time, the temperature monitoring function of the NTC thermistor ensures temperature safety during the treatment process. Furthermore, it can transmit treatment-related data to an external smart terminal via the Bluetooth module, thereby improving the accuracy, safety, and overall intelligence level of pelvic floor rehabilitation therapy from multiple dimensions.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-5This invention provides a portable pelvic floor muscle low-frequency magnetic stimulation rehabilitation device: It includes a portable case 1 for storage and support, a therapeutic cushion 3 that can be installed and stored inside the portable case 1, and a magnetic stimulation head module 5 fixedly positioned at the center of the bottom of the cushion 3. A controller 2 for unified control of the entire device is connected and installed externally to the portable case 1. This controller 2 integrates a control switch 21 for start / stop and parameter adjustment, an indicator light 22 for displaying the device's operating status, a PLC main control board 23 for core calculation and control functions, and a Bluetooth module 24 supporting wireless data transmission. The therapeutic cushion 3 is fixedly installed at the top inside the portable case 1. A dedicated receiving box 4 is carved out and installed at the bottom of the cushion 3. The receiving box 4 is used to house the magnetic stimulation head module 5, and the magnetic stimulation head module 5 includes a magnetic core 51 for magnetic conduction. The device includes an excitation coil 52 for generating a biomagnetic field and a magnetic shielding layer 53 for reducing stray magnetic field diffusion. The magnetic shielding layer 53 completely covers the outside of the magnetic core 51 and the excitation coil 52, while the excitation coil 52 is wound evenly around the outer surface of the magnetic core 51. Inside the housing 4, a low-frequency pulse magnetic field generating unit 6 and an NTC thermistor 7 for temperature acquisition are also provided. An embedded electromyography (EMG) signal acquisition unit 8 is mounted on the top of the housing 4. A rechargeable lithium battery pack 9 that powers the entire device is located on one side of the interior of the portable case 1. The embedded EMG signal acquisition unit 8 is further provided with a surface electrode pair 81 for contacting the acquired signal and a preamplifier 82 for amplifying weak electrical signals. The rechargeable lithium battery pack 9 is connected to a power management unit 91 for stabilizing output and managing power supply status.

[0020] Specifically, the portable case 1 is equipped with a handle 11, an anti-slip silicone pad 12, a first electromagnetic plate 13, a lid 14, a second electromagnetic plate 15, a recess 16, and a support column 17. One end of the support column 17 is fixedly connected to both sides of the middle of the interior of the portable case 1, and the other end extends upward to provide stable support for the seat 3. The seat 3 is embedded in the recess 16 for positioning and installation. The handle 11 is fixedly installed at the middle position on one side of the exterior of the portable case 1. The anti-slip silicone pad 12 is fixedly connected to the bottom outer surface of the portable case 1. The lid 14 is hinged to the top of one side of the portable case 1. This structural design makes the overall structure of the portable case stable. The pre-set handle makes it convenient for users to grip and carry the transfer device. The anti-slip silicone pad can increase the friction of the contact surface to ensure that the device remains stable during use and will not move at will. The support column provides stable and reliable support for the seat above. The seat embedded in the recess can further limit horizontal displacement and prevent the seat from shifting or misaligning during use.

[0021] Specifically, the first electromagnetic plate 13 is fixedly embedded around the top of the portable case 1, and the second electromagnetic plate 15 is fixedly embedded around the bottom of the case lid 14. The installation positions of the first electromagnetic plate 13 and the second electromagnetic plate 15 correspond one-to-one. Through the mutual magnetic attraction between the two electromagnetic plates, the case lid and the case body can be tightly closed and locked, preventing the case lid from being accidentally opened during the process of carrying, transferring or storing the device. This not only avoids the internal components from falling out and being damaged, but also enhances the overall sealing and reliability of the device for portable movement.

[0022] Specifically, the anti-slip silicone pad 12 is fixedly attached to the bottom outer surface of the portable case 1 to increase the friction between the bottom of the device and the placement surface, preventing the device from sliding and shifting. This design ensures that the device will not slide or shift in the front-back or left-right directions when in use, especially when the user's weight applies pressure to the case through the seat cushion, effectively improving the safety of the device during use and the comfort of the user.

[0023] Specifically, the low-frequency pulse magnetic field generating unit 6 is electrically connected to the excitation coil 52 of the magnetic stimulation head module 5 and the PLC main control board 23 of the controller 2, respectively. It is used to generate a low-frequency pulse excitation signal of a set frequency according to the treatment requirements. After receiving the control command issued by the PLC main control board, the unit generates a pulse current with a specific frequency and output intensity that meets the parameter requirements. The pulse current is then sent to the excitation coil to drive the coil to generate a bio-stimulation magnetic field that meets the treatment requirements, and finally achieves precise magnetic stimulation treatment for the pelvic floor muscle area.

[0024] Specifically, the NTC thermistor 7 is embedded inside the memory foam 32 of the cushion 3 and is electrically connected to the PLC main control board 23. It is used to collect temperature change data of the working area of ​​the device in real time. When the collected temperature value exceeds the preset safety threshold, the PLC main control board can automatically send control commands to reduce the output power of magnetic stimulation or directly stop the magnetic stimulation output to prevent local overheating during the operation of the device from causing burns or other accidental injuries to the user. This ensures the safety and reliability of the entire treatment process from the hardware level.

[0025] Specifically, the embedded electromyography (EMG) signal acquisition unit 8 acquires the native EMG signals of the user's pelvic floor muscles through surface electrodes 81 attached to the corresponding positions. The weak raw signals are amplified and noise-reduced by the preamplifier 82 and then transmitted to the PLC main control board 23 for analysis and processing. These acquired EMG signals can be used to assess the activity status and contraction ability of the pelvic floor muscles in real time, providing objective data for adjusting output parameters during treatment, realizing closed-loop feedback treatment based on the user's real-time status, and effectively improving the rehabilitation effect of the pelvic floor muscles.

[0026] Specifically, the Bluetooth module 24 establishes an electrical connection with the PLC main control board 23, which can wirelessly transmit the user's electromyographic signals and the current treatment parameters collected by the device to an external smart terminal device. Users or attending physicians can intuitively view real-time treatment data and historical treatment records through smart terminals such as mobile APPs. They can also remotely adjust the treatment plan according to the user's actual recovery situation, effectively improving the convenience of using the device and the overall level of intelligence in treatment.

[0027] The working principle of this implementation scheme is as follows: The user sits on the cushion 3 provided with the pelvic floor rehabilitation device. After confirming that the device is connected normally, the user starts the entire treatment device through the control switch 21 set on the controller 2. After the device is started, the PLC main control board 23 will output corresponding control signals according to the preset treatment plan stored in the system or the personalized treatment plan received from the external smart terminal via Bluetooth module 24. This precisely controls the low-frequency pulse magnetic field generating unit 6 to generate an excitation signal that meets the requirements of the plan. Subsequently, the excitation signal is transmitted to the magnetic stimulation head module 5, driving the excitation coil 52 inside the module to generate a low-frequency pulse magnetic field with stable parameters. This allows the magnetic field to act precisely on the pelvic floor muscle area of ​​the human body, completing the magnetic stimulation treatment process. At the same time, the embedded electromyography signal acquisition unit 8 on the device will collect the electromyography signals generated during the contraction and relaxation of the pelvic floor muscles in real time through the arranged surface electrode pairs 81. The acquired raw weak electromyographic signals are filtered and amplified by the preamplifier 82 before being fed back to the PLC main control board 23. The PLC main control board can monitor the pelvic floor muscle response to stimulation based on the acquired real-time electromyographic signals, dynamically adjust the output treatment parameters, and adapt to the real-time status of different users. During the operation of the device, the NTC thermistor 7 located in the working area continuously monitors the working temperature of the core components. Once an abnormal temperature occurs, it will trigger safety regulation to ensure the safety and stability of the treatment process. The entire pelvic floor rehabilitation device is powered by a rechargeable lithium battery pack 9. The matching power management unit 91 manages the charging and discharging process efficiently and safely, extending the device's battery life and battery life. After a treatment is completed, the device can upload all the data of this treatment to the bound external smart terminal via the Bluetooth module 24 for subsequent rehabilitation effect evaluation and treatment record recording.
