Description

Technical Field

[0001] This invention relates to the field of fascia care equipment technology, specifically a mechanically integrated pulsed electrical stimulation intervention device with independent stimulation channels for the fascial chain. Background Technology

[0002] With increasing health awareness, myofascial chain-related discomfort has become a common health problem, leading to a growing market demand for myofascial chain intervention devices. Existing myofascial care devices are mainly divided into mechanical massage devices and pulsed electrical stimulation devices. Mechanical massage devices often use a single massage head or a simple transmission structure, resulting in fixed massage angles and poor fit, making it difficult to accurately cover different parts of the myofascial chain. Pulsed electrical stimulation devices are mostly designed with planar electrodes, lacking synergy with mechanical massage, thus limiting their intervention effects.

[0003] Existing EMS electrical stimulation devices are mostly designed with planar electrodes, which can only act on the surface of muscles within 3mm and lack synergistic logic with mechanical massage. The pulsed electrical stimulation of this invention differs from traditional EMS. Through the customization of independent channel parameters and targeted arrangement design, it achieves full-chain activation of the fascial chain. At the same time, it is combined with the physical stimulation of mechanical massage to form a dual intervention of physical and electrophysiological methods, which solves the problem of limited intervention effect of traditional devices. Therefore, those skilled in the art provide a mechanically integrated pulsed electrical stimulation intervention device with independent stimulation channels for the fascial chain to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to provide a mechanically integrated pulsed electrical stimulation intervention device with an independent stimulation channel for the fascial chain, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0008] As a further embodiment of the present invention: the intervention mechanism includes a fixed frame, a transmission component, an intervention component, a linkage rod, a driving component, a transmission wheel, a drive motor, a drive wheel, a fixed plate, a movable groove, a mounting block, and a movable block. The massage pad is provided with a fixed frame in a ring shape. The fixed frames are connected to the transmission components in an L-shaped structure. A fixed plate is fixedly connected to one side of the fixed frame. A drive motor is provided on the fixed plate. The output end of the drive motor is fixedly connected to the drive wheel. The side of the massage pad closest to the drive wheel is movably connected to the transmission wheel. A protrusion is provided on the transmission wheel. A driving component is slidably connected to the fixed plate. A transmission groove is provided on the driving component. The protrusion is located on the transmission groove.

[0009] As a further embodiment of the present invention: each of the fixed frames is movably connected to a movable block, the movable blocks are fixedly connected to an intervention member, an installation block is fixedly connected to the intervention member, and the transmission member is provided with a movable groove, with the installation block located in the movable groove of the transmission member.

[0010] As a further aspect of the present invention: a massage protrusion is provided on one side of the intervention component, the massage protrusion is made of medical silicone, and a pressure sensor is also provided between the intervention component and the movable block, the pressure sensor being electrically connected to the control module inside the host.

[0011] As a further embodiment of the present invention: the adjustment mechanism includes a rotating seat, an extension seat, a first damping shaft, a transmission rack, a second damping shaft, a guide frame, a limiting groove, and a limiting block. The main body is movably connected to both sides of the first damping shaft. The main body is movably connected to the rotating seat through the first damping shaft. A guide frame is provided on one side of the rotating seat. The rotating seat is movably connected to the extension seat through the guide frame. A transmission rack is fixedly connected to one side of the extension seat. A third damping shaft is provided inside the rotating seat. A limiting wheel is movably connected to the rotating seat through the third damping shaft. The limiting wheel and the transmission rack cooperate with each other.

[0012] As a further embodiment of the present invention: a second damping shaft is provided on the side of the extension seat away from the transmission rack, and a massage pad is movably connected to the second damping shaft.

[0013] As a further embodiment of the present invention: a limiting groove is formed on the transmission rack, and a limiting block is fixedly connected inside the rotating seat, with the limiting block located inside the limiting groove of the transmission rack.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] After receiving the operation command, the host control module sends a start signal to the drive motor. The drive motor is powered on and runs, and the drive wheel fixed at its output end rotates synchronously. The drive wheel drives the transmission wheel that it cooperates with to rotate. The protrusion on the transmission wheel is embedded in the transmission groove of the drive component. When the transmission wheel rotates, the protrusion slides eccentrically along the transmission groove, pushing the drive component to perform reciprocating linear motion on the fixed plate. The drive component is hinged at one end to the nearest L-shaped transmission component. The reciprocating motion of the drive component drives the transmission component to swing around the movable connection point of the fixed frame. The transmission components are synchronously linked by the linkage rod connected by ball joints. When the transmission component swings, the mounting block moves along the movable groove. The intervention component fixed between the movable blocks rises and falls synchronously with the transmission component. The medical silicone massage protrusions on its surface repeatedly contact and press the human fascia chain area to achieve mechanical massage.

[0016] The pressure sensor between the intervention component and the moving block detects the pressure applied by the massage protrusions to the human body in real time. The pressure sensor transmits the detected pressure electrical signal to the control module of the main unit. The control module displays the current pressure value in real time on the display screen. If the pressure value is lower than the preset threshold, the control module increases the speed of the drive motor and increases the output torque of the drive wheel, thereby increasing the extension and retraction stroke of the intervention component and enhancing the pressure. If the pressure value is higher than the preset threshold, the control module decreases the speed of the drive motor and reduces the extension and retraction stroke to avoid excessive pressure and discomfort. The main unit control module can synchronously or alternately start mechanical massage and pulsed electrical stimulation. The feedback signal from the pressure sensor can be used to adjust the intensity of the pulsed electrical stimulation.

[0017] Depending on the area of ​​application, the user first adjusts the left and right angles of the rotating seat using the first damping pivot, and then adjusts the pitch angle of the massage pad using the second damping pivot. This aligns the ring electrodes and intervention mechanism of the massage pad with the target fascial chain area. The user then manually extends the extension seat to adjust the distance between the massage pad and the main unit, adapting the length to different parts of the body. During the extension and retraction process, the limiting blocks and limiting grooves ensure stable movement. After adjustment, the massage pad can stably fit the target area of ​​the body, ensuring that the mechanical massage of the intervention mechanism and the pulsed electrical stimulation of the electrodes can accurately act on the fascial chain, avoiding a decrease in intervention effect due to poor fit.

[0027] 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.

[0028] Example 1

[0029] Reference Figures 1-8This embodiment provides a mechanically integrated pulsed electrical stimulation intervention device with an independent stimulation channel for the fascial chain, including a main unit 1, an adjustment mechanism 2, a massage pad 3, an intervention mechanism 4, and electrodes 5. The adjustment mechanism 2 is movably connected to both sides of the main unit 1, and the massage pad 3 is movably connected to the side of the adjustment mechanism 2 away from the main unit. The intervention mechanism 4 with gear transmission is set in the center of the massage pad 3, and the electrodes 5 are arranged in a ring around the intervention mechanism 4 in the massage pad 3.

[0030] The host 1 is equipped with an operation panel and a display screen. The display screen is electrically connected to the pulse electrical stimulation control module. The host 1 is also equipped with a rechargeable lithium battery. The host 1 has a charging interface on its side. The electrode 5 is an adjustable electrode and is electrically connected to the battery.

[0031] Among them, the independent stimulation channel of electrode 5 corresponds one-to-one with the pulse electrical stimulation control module of host 1. Users can select single channel stimulation or multi-channel synergistic stimulation through the operation panel. For the cervical fascia chain, the electrode channel corresponding to the platysma muscle node can be activated separately, and the square wave pulse with a frequency of 50Hz and an intensity of 10mA can be adjusted. Alternatively, three sets of electrode channels can be activated simultaneously, and different parameters can be set to adapt to the activation of different nodes of the fascia chain.

[0032] The intervention mechanism 4 includes a fixed frame 401, a transmission component 402, an intervention component 403, a linkage rod 404, a driving component 405, a transmission wheel 406, a drive motor 407, a drive wheel 408, a fixed plate 409, a movable groove 410, a mounting block 411, and a movable block 412. The massage pad 3 is provided with a fixed frame 401 in a ring shape. The fixed frames 401 are connected to the transmission components 402 in an L-shaped structure. A fixed plate 409 is fixedly connected to one side of the fixed frame 401. A drive motor 407 is provided on the fixed plate 409. The output end of the drive motor 407 is fixedly connected to the drive wheel 408. The side of the massage pad 3 closest to the drive wheel 408 is movably connected to the transmission wheel 406. A protrusion 414 is provided on the transmission wheel 406. The fixed plate 409 is slidably connected to the driving component 405. A transmission groove 413 is provided on the driving component 405. The protrusion 414 is located on the transmission groove 413.

[0033] Each of the fixed frames 401 is movably connected to a movable block 412, and an intervention member 403 is fixedly connected between the movable blocks 412. An installation block 411 is fixedly connected to the intervention member 403, and a movable groove 410 is opened on the transmission member 402. The installation block 411 is located in the movable groove 410 of the transmission member 402.

[0034] The intervention component 403 has a massage protrusion on one side, which is made of medical silicone. A pressure sensor is also provided between the intervention component 403 and the movable block 412. The pressure sensor is electrically connected to the control module inside the host 1.

[0035] After receiving the operation command, the control module of host 1 sends a start signal to the drive motor 407, energizing the drive motor 407. The drive wheel 408, fixed at its output end, rotates synchronously, driving the transmission wheel 406 that it cooperates with to rotate. The protrusion on the transmission wheel 406 is embedded in the transmission groove 413 of the drive component 405. When the transmission wheel 406 rotates, the protrusion 414 slides eccentrically along the transmission groove 413, pushing the drive component 405 to perform reciprocating linear motion on the fixed plate 409. The drive component 405 and the... One end of the adjacent L-shaped transmission component 402 is hinged. The reciprocating motion of the drive component 405 drives the transmission component to swing around the movable connection point of the fixed frame 401. The transmission components 402 are connected synchronously by the linkage rod 404 connected by ball joints. When the transmission component 402 swings, the mounting block 411 moves along the movable groove 410. The intervention component 403 fixed between the movable blocks 412 rises and falls synchronously with the transmission component 402. The medical silicone massage protrusions on its surface repeatedly contact and press the human fascia chain area to achieve mechanical massage.

[0036] The pressure sensor between the intervention component 403 and the movable block 412 detects the pressure applied to the body by the massage protrusions in real time. The pressure sensor transmits the detected pressure electrical signal to the control module of the host 1. The control module displays the current pressure value in real time on the display screen. If the pressure value is lower than the preset threshold, the control module increases the speed of the drive motor 407 and increases the output torque of the drive wheel 408, so that the extension stroke of the intervention component 403 is increased and the pressure is enhanced. If the pressure value is higher than the preset threshold, the control module reduces the speed of the drive motor and reduces the extension stroke to avoid excessive pressure and discomfort. The host control module can synchronously or alternately start mechanical massage and pulse electrical stimulation. The feedback signal of the pressure sensor can be used to adjust the intensity of pulse electrical stimulation.

[0037] Example 2

[0038] Reference Figures 1-4 This embodiment is based on the previous embodiment, but differs in that the adjustment mechanism 2 includes a rotating seat 201, an extension seat 202, a first damping shaft 203, a transmission rack 204, a second damping shaft 205, a guide frame 206, a limiting groove 207, and a limiting block 208. The first damping shaft 203 is movably connected to both sides of the main body 1. The rotating seat 201 is movably connected to the main body through the first damping shaft 203. A guide frame 206 is provided on one side of the rotating seat 201. The extension seat 202 is movably connected to the rotating seat 201 through the guide frame 206. A transmission rack 204 is fixedly connected to one side of the extension seat 202. A third damping shaft 209 is provided inside the rotating seat 201. A limiting wheel 210 is movably connected to the rotating seat 201 through the third damping shaft 209. The limiting wheel 210 and the transmission rack 204 cooperate with each other.

[0039] A second damping shaft 205 is provided on the side of the extension seat 202 away from the transmission rack 204, and a massage pad 3 is movably connected to the second damping shaft 205.

[0040] A limiting groove 207 is provided on the transmission rack 204, and a limiting block 208 is fixedly connected inside the rotating seat 201. The limiting block 208 is located inside the limiting groove 207 of the transmission rack 204.

[0041] The main unit 1 is connected to the rotating base 201 on both sides via the first damping shaft 203. When the rotating base is manually pushed, the internal damping structure of the first damping shaft provides friction. After rotating to the target angle, it can be directly fixed without additional locking parts. The side of the extension base 202 away from the transmission rack 204 is connected to the massage pad 3 via the second damping shaft 205. When the massage pad 3 is manually flipped, the electrodes 5 and intervention mechanism 4 of the massage pad 3 can conform to the curve of the human body. The damping friction resistance is used to keep the adjusted angle stable, avoiding the massage pad from shifting due to vibration or human movement during use. At the same time, no tools are required for manual adjustment, making the operation convenient.

[0042] The rotating seat 201 is movably connected to the extension seat 202 via the guide frame 206. The transmission rack 204 on one side of the extension seat 202 meshes with the limiting wheel 210 inside the rotating seat. When the extension seat is manually pulled or pushed, the transmission rack 204 slides along the guide frame 206, driving the limiting wheel 210 to rotate, thereby realizing the extension and retraction of the extension seat 202. The limiting groove 207 on the transmission rack 204 cooperates with the limiting block 208 inside the rotating seat. When sliding, the limiting block 208 is always stuck in the limiting groove 207, restricting the sliding trajectory of the transmission rack 204, preventing the extension seat 202 from coming out of the rotating seat 201, and ensuring the linearity of the extension and retraction movement.

[0043] According to the area of ​​application, the user first adjusts the left and right angles of the rotating seat 201 through the first damping pivot 203, and then adjusts the pitch angle of the massage pad 3 through the second damping pivot 205, so that the annular electrode 5 and the intervention mechanism 4 of the massage pad 3 are aligned with the target fascial chain area. Then, the user adjusts the distance between the massage pad 3 and the main unit 1 by manually extending the extension seat 202 to adapt to the length of different parts of the human body. During the extension and retraction process, the limiting block 208 and the limiting groove 207 ensure stable movement. After adjustment, the massage pad 3 can stably fit the target part of the human body, ensuring that the mechanical massage of the intervention mechanism 4 and the pulse electrical stimulation of the electrode 5 can accurately act on the fascial chain, avoiding the decrease in intervention effect due to poor fit.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
