Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a dynamic electroacupuncture system for the rehabilitation of cerebrovascular diseases based on electromyographic signal feedback from spastic muscle groups. Background Technology

[0002] Acupuncture is often used in the rehabilitation of cerebrovascular diseases, including electroacupuncture rehabilitation for spastic muscle groups. This involves applying electrical current to acupoints using electroacupuncture, and the rehabilitation effect is achieved through electrical signal feedback from muscle contractions at the acupoints. While electroacupuncture rehabilitation for spastic muscle groups is widely used, existing rehabilitation systems have several structural design flaws that affect treatment effectiveness and patient experience. These flaws are detailed below: Traditional electroacupuncture systems often use alligator clips or plug-in interfaces to connect the electrical signal controller and electrodes. During the rehabilitation treatment of cerebrovascular diseases, the body parts are prone to frequent shaking, and the alligator clips and plug-in interfaces are prone to loosening. The alligator clips are prone to poor contact due to the patient's limb movements, and the plug-in interfaces lack an elastic locking structure, causing interruption of electrical signal transmission or noise interference, making it difficult to ensure the continuity and accuracy of electromyographic signal feedback. In addition, the connection between the power cord and the electrode is mostly a rigid plug without a buffer design, which can easily fall off when pulled by external force, causing the feedback mechanism to fail. In addition, when using alligator clips to hold electroacupuncture needles, the operator needs to press with both hands, which is cumbersome and time-consuming. Especially when treating multiple acupoints at the same time, the operation efficiency is extremely low. Furthermore, after the alligator clips are installed, the electroacupuncture needles will bend and deform, affecting the continuity and accuracy of electromyographic signal feedback. Summary of the Invention

[0003] This invention relates to a dynamic electroacupuncture system for cerebrovascular disease rehabilitation based on electromyographic signal feedback from spastic muscle groups. This dynamic electroacupuncture system achieves precise rehabilitation treatment through multi-structure synergy. The stabilizing structure utilizes a support spring and a stabilizing block to elastically engage the plug, ensuring stable electrical signal transmission. An adaptive electrode structure and an electrical signal feedback structure form a conductive circuit, and the power cord is locked in place by slots in the positioning seat and clamping plate, solving the problem of unstable conductivity in traditional systems. Acupoint positioning holes in the wearing cloth, combined with an extended positioning sleeve and a magnetic ring, enable precise positioning of the electroacupuncture needles. A vibration transmission spring provides elastic cushioning for the electrode pads, and the height of the support plate is adjustable, improving wearing comfort. The electroacupuncture needles are quickly installed via threads and the extended positioning sleeve, and the magnetic ring enables rapid magnetic engagement between the sleeve and the support plate. The overall structure balances stability, precision, and ease of operation, effectively improving the rehabilitation treatment effect for cerebrovascular diseases.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. Based on the described 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.

[0024] Example 1: Please refer to Figures 1 to 12 : This invention proposes a dynamic electroacupuncture system for cerebrovascular disease rehabilitation based on electromyographic signal feedback from spastic muscle groups. The system includes: an electrical signal controller 1; a set of sockets at the bottom of one side of the controller 1, with plugs 504 installed at these sockets for electrical connection; a set of parallel and evenly distributed positioning sleeves 101 on one side of the controller 1; a vertical sliding rod 201 inserted inside each positioning sleeve 101; a stabilizing block 202 at the bottom of each sliding rod 201; the sliding rod 201 and stabilizing block 202 are integrally formed, with the stabilizing block 202 being a semi-circular sleeve structure; and a support spring installed on the outer side of each sliding rod 201, positioned between the stabilizing block 202 and the positioning sleeves 101. The support spring elastically presses the stabilizing block 202 downwards. An annular groove is opened on the outer side of the plug 504, and the bottom of the stabilizing block 202 extends into the interior of the annular groove. A lifting block 203 is installed above the sliding rod 201. The lifting block 203 is located above the positioning sleeve 101. The sliding rod 201, the stabilizing block 202, and the lifting block 203 cooperate to form a stabilizing structure 2. Specifically, the support spring pushes the stabilizing block 202 into the annular groove of the plug 504 to form an elastic engagement, preventing the plug 504 from loosening and falling out of the socket of the electrical signal controller 1. The lifting block 203 makes it easy for the operator to lift the sliding rod 201 upwards, so that the stabilizing block 202 is disengaged from the annular groove, realizing the quick disassembly and installation of the plug 504, improving connection stability and ease of operation. In this embodiment, an electrode plate 401 is installed on one side of the power cord 503, and a wearing cloth 3 is installed at the bottom of the electrode plate 401. A set of straps 301 is provided on one side of the wearing cloth 3, and Velcro is provided at the bottom of the straps 301. A set of Velcro corresponding to the straps 301 is provided on the other side of the wearing cloth 3. The wearing cloth 3 is worn on the head and upper and lower limbs according to actual needs. The wearing cloth 3 is used in conjunction with the straps 301 and Velcro for binding and positioning. A power cord 503 is provided on one side of the plug 504. A set of alignment rings 303 is installed on the upper part of the wearing cloth 3. A set of positioning holes is opened at the edge of the alignment rings 303. A set of stabilizing pins 304 is installed between the wearing cloth 3 and the positioning holes. Specifically, the stabilizing pins 304 pass through the positioning holes of the alignment rings 303 and fix them to the wearing cloth 3, so that the alignment rings 303 are firmly installed on the wearing cloth 3. This provides an installation base for the components of the electrode plate 401 and the electrical signal feedback structure 5 and provides a quick positioning effect, thereby enhancing the connection strength and stability of the overall structure. In this embodiment, the electrode pad 401 is installed inside the alignment ring 303, with the inner positions of the electrode pad 401 and the alignment ring 303 corresponding. A double-sided adhesive is adhered to the bottom of the electrode pad 401, with the bottom of the double-sided adhesive adhering to the top of the wearing cloth 3 for positioning. A positioning seat 407 is provided on one side of the electrode pad 401, and an opening groove is provided on one side of the alignment ring 303. The positioning seat 407 passes through the interior of the opening groove. Specifically, the double-sided adhesive enables quick adhesion and fixation of the electrode pad 401 to the wearing cloth 3, facilitating installation and replacement; the positioning seat 407, passing through the opening groove of the alignment ring 303, further limits the electrode pad 401, preventing it from shifting on the wearing cloth 3 and ensuring stable acquisition of electromyographic signals by the electrode pad 401. A clamping plate 502 is installed above the positioning seat 407, and a vertical second positioning rod 501 is provided on one side of the positioning seat 407. The second positioning rod 501, clamping plate 502, power cord 503, and plug 504 are mutually compatible. Together, they form an electrical signal feedback structure 5. The second positioning rod 501 is a cylindrical structure. A positioning hole is opened on one side of the clamping plate 502. The second positioning rod 501 passes through the interior of the positioning hole. A support spring is installed on the outer side of the second positioning rod 501. A ring groove positioning snap ring is installed above the second positioning rod 501. The support spring is installed between the snap ring and the clamping plate 502. The support spring elastically presses the clamping plate 502 downward, stretches the clamping plate 502 upward, and then rotates it to one side. At this time, it is convenient to connect and disconnect the conductive head of the power cord 503 and the power cord 503. Specifically, the support spring keeps the clamping plate 502 elastically clamping the power cord 503, ensuring that the power cord 503 is stably connected to the electrode plate 401. By stretching and rotating the clamping plate 502, the power cord 503 can be quickly released or clamped, realizing convenient connection and separation of the power cord 503 and the electrode plate 401, which facilitates the overall assembly, maintenance, storage, and replacement of parts. In this embodiment, a positioning ring is provided on the outer side of the power cord 503. One side of the positioning ring has a chamfer. A slot corresponding to the positioning ring is opened at the top of the positioning seat 407 and the bottom of the clamping plate 502. The positioning ring and the power cord 503 extend into the slot. The positioning seat 407 and the clamping plate 502 cooperate with the slot to achieve the effect of quick locking of the electrode plate 401 and the power cord 503. Specifically, the positioning ring on the outer side of the power cord 503 precisely cooperates with the slot of the positioning seat 407 and the clamping plate 502. Under the pressure of the support spring, a mechanical locking structure is formed to prevent the power cord 503 from loosening or falling off during use. A transverse conductive groove is opened on one side of the conductive sleeve 403. One side of the power cord 503 extends into the conductive groove. A conductive sleeve is installed on the inner side of the conductive groove. The electric spring 408, electrode 401, vibration transmission spring 402, conductive sleeve 403, first positioning rod 404, lifting plate 405, locking bolt 406, positioning seat 407, and conductive spring 408 work together to form the adaptive electrode structure 4. After the positioning seat 407 and clamping plate 502 position the power line 503, the chamfer of the positioning ring on the outer side of the power line 503 is subjected to compressive force. At this time, one side of the power line 503 compresses the conductive spring 408, generating elastic pressure to ensure that a tight electrical connection is formed between the power line 503, the conductive sleeve 403, and the electrode 401. The adaptive electrode structure 4, through the collaboration of multiple components, realizes stable and reliable electrical signal transmission and feedback between the electrode 401 and the electrical signal controller 1, and at the same time has a certain adaptive adjustment capability to adapt to the patient's limb movement. In this embodiment, a vertical extension sleeve 6 is installed above the electrode plate 401, a magnetic ring 601 is installed at the bottom of the extension sleeve 6, and an electric needle 7 is installed inside the extension sleeve 6. A set of acupoint positioning holes 302 are made on the basis of the wearing cloth 3. The bottom of the electric needle 7 is inserted into the acupoint positioning hole 302. Specifically, the acupoint positioning hole 302 provides a precise insertion guide for the electric needle 7, ensuring that the electric needle 7 accurately pierces the target acupoint and avoids the acupuncture position deviation from affecting the treatment effect; at the same time, the wearing cloth 3 can help fix the electric needle 7 to prevent it from shifting or shaking during treatment. In this embodiment, a vibration transmission spring 402 is installed above the electrode plate 401, with its bottom extending to the inner side of the electrode plate 401. A conductive sleeve 403 is installed above the vibration transmission spring 402. The vibration transmission spring 402 achieves elastic positioning and elastic support for the electrode plate 401 and the conductive sleeve 403. A vertical first positioning rod 404 is provided on one side of the conductive sleeve 403, and a support plate 405 is installed on the outer side of the first positioning rod 404. A mounting hole is opened on one side of the support plate 405, through which the first positioning rod 404 passes. Inside, a locking bolt 406 is installed on one side of the mounting hole. Tightening the locking bolt 406 achieves a stable effect between the first positioning rod 404 and the support plate 405. After loosening the locking bolt 406, the support plate 405 can be adjusted up and down as needed. Specifically, the vibration transmission spring 402 provides elastic buffer for the electrode pad 401, reducing displacement of the electrode pad 401 or signal interference caused by the patient's limb movement. The support plate 405 is fixed to the first positioning rod 404 by the locking bolt 406 and can be flexibly adjusted in height to adapt to different patient body parts, providing stable support for the extension sleeve 6 and the electroacupuncture needle 7. In this embodiment, a stepped groove is provided on the inner side of the extension sleeve 6. The upper part of the magnetic ring 601 extends to the inner side of the stepped groove, and the bottom of the magnetic ring 601 extends to the inner side of the support plate 405. With the cooperation of the magnetic ring 601, the extension sleeve 6 and the support plate 405 can be quickly and stably connected. A sliding hole is opened on one side of the extension sleeve 6, and the first positioning rod 404 passes through the inside of the sliding hole. The sliding hole, in conjunction with the bottom position of the magnetic ring 601, positions the extension sleeve 6 circumferentially, ensuring that the direction of the electric needle 7 is stable during use and that the needle puncture accuracy is not affected by shaking. The magnetic ring 601 uses magnetic force to quickly attract and fix the extension sleeve 6 and the support plate 405. To simplify the installation process and improve assembly efficiency, the knob of the electric needle 7 has a threaded connecting block at its bottom. The threaded connecting block is installed on the inner side of the extension sleeve 6. After the electric needle 7 is installed, a slight rotation is performed. At this time, with the cooperation of the threaded connecting block, the electric needle 7 can be quickly positioned. This solves the problem that the traditional electric needle 7 requires electrical connection with alligator clips and electrical signal controller 1. Specifically, through the threaded engagement between the threaded connecting block and the extension sleeve 6, the electric needle 7 can be quickly screwed in and accurately positioned. Compared with the traditional alligator clip connection method, the operation is simpler, the connection is more stable, and the problem of unstable electrical signal transmission caused by poor contact is avoided.

[0025] Example 2, based on Example 1, such as Figures 1-11 As shown, the adaptive electrode structure 4, the extension sleeve 6, and the magnetic ring 601 are made of conductive materials. The conductive materials enable smoother signal interaction between the electric needle 7, the electrode plate 401, and the electrical signal controller 1, thereby enhancing the feedback control performance of the entire system.

[0026] The working principle of this embodiment: Align the plug 504 with the socket at the bottom side of the electrical signal controller 1 and press the plug 504 down. At this time, the support spring pushes the stabilizing block 202 into the annular groove on the outer side of the plug 504, completing the stable electrical connection between the plug 504 and the electrical signal controller 1. If you need to remove the plug 504, pull the lifting block 203 upward, which will cause the sliding rod 201 and the stabilizing block 202 to disengage from the annular groove. At this time, the plug 504 can be pulled out. Based on the patient's rehabilitation needs for cerebrovascular disease, determine the acupoints to be stimulated, such as the head and upper and lower limbs; cover the corresponding area with the cloth 3, wrap the limbs or head with the strap 301, and use the Velcro at the bottom of the strap 301 to tie and fix it to the other side of the cloth 3, and adjust the tightness to be comfortable and the cloth 3 will not slip. Remove the protective layer of the double-sided adhesive at the bottom of the electrode 401 and attach the electrode 401 to the inner side of the alignment ring 303 on the wearing cloth 3; at the same time, make the positioning seat 407 on one side of the electrode 401 pass through the opening groove of the alignment ring 303 to complete the initial fixation of the electrode 401. Pull the clamping plate 502 upward and rotate it to one side to release the clamping force. Insert the end of the power cord 503 with the conductive head between the positioning seat 407 and the clamping plate 502. Then rotate it in the opposite direction and lower the clamping plate 502. Use the elasticity of the support spring to press the clamping plate 502 and the slot of the positioning seat 407 to lock the power cord 503. At this time, the positioning ring on the outer side of the power cord 503 is pressed, and one side of it squeezes the conductive spring 408 to achieve a stable electrical connection between the power cord 503 and the electrode plate 401. The lifting plate 405 is placed on the outside of the first positioning rod 404. According to the actual acupoint position and limb condition of the patient, the lifting plate 405 is adjusted up and down to a suitable height, and then the locking bolt 406 is tightened to fix it. The magnetic ring 601 is aligned with the stepped groove on the inner side of the extension sleeve 6 and the inner side of the lifting plate 405 respectively. The magnetic force is used to make the extension sleeve 6 and the lifting plate 405 quickly and stably combine. At the same time, the sliding hole cooperates with the magnetic ring 601 to perform circumferential positioning of the extension sleeve 6. Align the threaded connecting block at the bottom of the electroacupuncture needle 7 with the inside of the extension sleeve 6, rotate the electroacupuncture needle 7 slightly, and screw the electroacupuncture needle 7 into the extension sleeve 6 through the threaded engagement to complete the installation and positioning; ensure that the tip of the electroacupuncture needle 7 passes through the acupoint positioning hole 302 on the wearing cloth 3, at which point the electroacupuncture needle 7 pierces the target acupoint; Turn on the power switch of the electrical signal controller 1. Based on the patient's condition and physical response, set appropriate electroacupuncture 7 stimulation parameters on the electrical signal controller 1, such as current intensity, frequency, and waveform. The system starts working. The electrode pad 401 collects electromyographic signals of the spastic muscle group and transmits them to the electrical signal controller 1 for analysis and processing via the power line 503. The controller adjusts the stimulation parameters of the electroacupuncture 7 in real time according to the feedback signal to perform dynamic electroacupuncture 7 treatment. After treatment, turn off the power to the electrical signal controller 1. If disassembly is required, reverse the above steps in sequence: first, adjust the parameters of the electrical signal controller 1 to the minimum and turn off the power; pull the clamping plate 502 upward and rotate to separate the power cord 503; loosen the locking bolt 406 to remove the lifting plate 405 and separate the magnetic ring 601 connection; rotate to remove the electrocautery needle 7; peel off the electrode plate 401; untie the strap 301 and remove the dressing cloth 3; finally, lift the lifting block 203, unplug the plug 504, and properly store all components.
