Description

Technical Field

[0001] This invention relates to the field of lymphedema rehabilitation technology, and more particularly to an electrostimulation-based lymphedema rehabilitation device. Background Technology

[0002] Lymphedema massage is the core of treatment. It uses gentle, targeted pushing techniques to guide stagnant lymph fluid back towards the heart, much like clearing a drain. This effectively reduces swelling, promotes the removal of metabolic waste, and lowers the risk of infection. Current methods use air-wave devices to apply pressure sequentially to the limbs, causing lymph fluid to flow back towards the heart. However, if the airbag positions remain unchanged, the pressure applied between multiple airbags will be less than at the center, leading to uneven pressure on the limbs. This uneven pressure can negatively impact the effectiveness of lymph fluid drainage. Summary of the Invention

[0003] This invention proposes an electrostimulation-based lymphedema rehabilitation device to address the aforementioned shortcomings of the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An electrically stimulated lymphedema rehabilitation device includes a housing and further includes:

[0006] An electrical stimulation mechanism, mounted on top of a housing, includes multiple electrode pads;

[0007] A limb support mechanism, which is installed on both sides of the housing, includes collar one and collar two;

[0008] A multi-segment massage mechanism, installed inside the housing, includes multiple airbags, one side of which is connected to a solenoid valve;

[0009] A uniform pressing mechanism, which is connected to a multi-segment massage mechanism, including a downward anti-sticking mechanism and a translation switching mechanism.

[0010] The electrical stimulation mechanism also includes a controller fixed to the top of the housing, the controller being electrically connected to multiple electrode pads;

[0011] A storage box is fixed to the top of the housing, and a lid is rotatably connected to the top of the storage box. The electrode sheet is fitted inside the storage box.

[0012] The limb support mechanism also includes mounting ports on both sides of the housing, and the first collar and the second collar are respectively fixed inside the mounting ports;

[0013] Both collar one and collar two have rubber rings fixed to their inner walls.

[0014] The multi-segment massage mechanism also includes multiple support plates fixed to the bottom of multiple airbags, with three collars fixed on both sides of the multiple support plates, and two collars three being fixedly connected to the airbags located on both sides respectively, and the multiple airbags being fixedly connected to each other.

[0015] First, attach multiple electrode pads to the limb, then the limb enters through ring one, then through ring three and the inside of the airbag, and finally exits through ring two.

[0016] Then the controller starts the recovery program;

[0017] The controller controls multiple air pumps to operate in sequence, causing multiple airbags to inflate sequentially, gradually increasing pressure from the distal end to the proximal end, and guiding the lymph fluid to flow in one direction.

[0018] Two movable blocks are fixed between the two collars, and the two movable blocks are fixed to the top of the multiple airbags;

[0019] Multiple air pumps are fixed to the top of the housing, and each of the multiple air pumps is connected to a multiple solenoid valve.

[0020] The translation switching mechanism includes a slide groove on both sides of the housing, a slider is slidably connected inside the slide groove, a motor is fixed inside one of the sliders, a screw is fixed at the output end of the motor, and one end of the screw is rotatably connected to the other slider.

[0021] The shell has two sliding grooves on both sides, and two sliders are slidably connected inside the sliding grooves. A screw is rotatably connected between the two sliders.

[0022] Both screw one and screw three have a pulley fixed at one end, and the two pulleys are externally connected by a belt.

[0023] The screw one and screw three are respectively threaded inside the two moving blocks.

[0024] The starter motor drives screw one to rotate, and screw one drives another screw three to rotate through a pulley and belt, causing two moving blocks to move along screw one and screw three. During the movement, the airbag, collar three and support plate below move, and at the same time, the moving frame, screw two, motor two, guide rod and slider three above move. Slider three slides on the slide rod.

[0025] The downward anti-sticking mechanism includes two sliding rods fixed to the inner wall of the housing. A slider three is sleeved on the outside of the two sliding rods. A motor two is fixed inside the slider three. A screw two is fixed at the output end of the motor two. A movable frame is threaded on the outside of the screw two. A guide rod is sleeved on the top of the movable frame. The top end of the guide rod is fixedly connected to the slider three. The bottom of the movable frame is fixedly connected to two movable blocks.

[0026] After all the airbags have been used to press on the limbs, the solenoid valve is opened to release the gas inside the airbags. The second motor is started, which drives the second screw to rotate forward, causing the moving frame to move down along the guide rod. The downward movement of the moving frame will push the moving block, the first screw, the third screw, the pulley, the belt, the first slider, the second slider, the airbag, the third collar, and the support plate down a specified distance. When the first slider moves down, it slides inside the first slide groove, and when the second slider moves down, it slides inside the second slide groove.

[0027] The controller is electrically connected to motor one, motor two, solenoid valve and air pump respectively.

[0028] Compared with existing technologies, the beneficial effects of this invention are:

[0029] 1. This invention directly acts on lymphatic vessels by installing an electrical stimulation mechanism: low-frequency current can precisely stimulate the smooth muscle of the lymphatic vessel wall, causing it to contract and relax autonomously, thereby accelerating lymph fluid flow; at the same time, electrical stimulation can also indirectly activate the "muscle pump" effect—causing the muscles surrounding the lymphatic vessels to contract synchronously, squeezing the lumen to push the lymph fluid to flow proximally; in addition, this mechanism can effectively improve local circulation and overall blood circulation, help relieve tissue fluid stasis, and further assist lymphatic return; by simulating the natural contraction pattern of muscles, it continuously promotes lymph fluid return like a "biological pump," ultimately achieving the effect of reducing edema.

[0030] 2. This invention achieves uniform massage by installing a uniform pressing mechanism: First, motor two is started, driving screw two to rotate clockwise, causing the moving frame to move downwards along the guide rod, thereby pushing the moving block, screw one, screw three, pulley, belt, slider one, slider two, airbag, collar three, and support plate to move synchronously downwards to a specified distance—slider one slides along slide groove one, and slider two slides along slide groove two; then motor one is started, driving screw one to rotate, and screw one drives another screw three to rotate synchronously through the transmission of pulley and belt, causing the two moving blocks to move along screw one and screw three respectively. During the movement, the airbags, collar three, and support plate below are displaced, while the moving frame, screw two, motor two, guide rod, and slider three above are also moved. Slider three slides along the slide rod. Subsequently, the controller controls multiple air pumps to operate in sequence, causing multiple airbags to inflate sequentially, gradually applying pressure from the distal end of the limb to the proximal end. By repeating the above cycle, the airbag pressure position changes, ensuring uniform pressure on the limb as a whole, avoiding differences in pressure intensity across different parts of the limb, effectively solving the problem of uneven pressure on the entire limb, and thus promoting lymphatic circulation more efficiently.

[0041] Example: Refer to Figures 1-6 A device for the rehabilitation of lymphedema through electrical stimulation, comprising a housing 1, and further comprising:

[0042] An electrical stimulation mechanism 2, which is mounted on top of the housing 1, includes multiple electrode plates 23;

[0043] The limb support mechanism 3 is installed on both sides of the housing 1 and includes a first collar 31 and a second collar 32.

[0044] The multi-segment massage mechanism 4 is installed inside the housing 1 and includes multiple airbags 42, one side of which is connected to a solenoid valve 46.

[0045] The uniform pressing mechanism 5 is connected to the multi-segment massage mechanism 4, including a downward anti-sticking mechanism and a translation switching mechanism.

[0046] The electrical stimulation mechanism 2 also includes a controller 24 fixed to the top of the housing 1, and the controller 24 is electrically connected to a plurality of electrode plates 23;

[0047] A storage box 21 is fixed to the top of the housing 1, and a cover 22 is rotatably connected to the top of the storage box 21. The electrode sheet 23 is sleeved inside the storage box 21.

[0048] The limb support mechanism 3 also includes mounting ports on both sides of the housing 1, with collar one 31 and collar two 32 respectively fixed inside the mounting ports;

[0049] Both collar 31 and collar 32 have rubber rings fixed to their inner walls.

[0050] The multi-segment massage mechanism 4 also includes multiple support plates 41 fixed to the bottom of multiple airbags 42. The two sides of the multiple support plates 41 are fixed with collars 43. The two collars 43 are respectively fixedly connected to the airbags 42 located on both sides. The multiple airbags 42 are fixedly connected to each other.

[0051] First, attach multiple electrode pads 23 to the limb, then the limb enters through the first collar 31, then enters the interior of the third collar 43 and the airbag 42, and then exits through the second collar 32;

[0052] Then controller 24 starts the rehabilitation program;

[0053] The controller 24 controls multiple air pumps 45 to operate in sequence, causing multiple air bags 42 to inflate in sequence, gradually increasing pressure from the distal end to the proximal end, and guiding the lymph fluid to flow in one direction.

[0054] Two movable blocks 44 are fixed between the two collars 43, and the two movable blocks 44 are fixed to the top of the multiple airbags 42;

[0055] Multiple air pumps 45 are fixed on the top of the housing 1, and the multiple air pumps 45 are respectively connected to multiple solenoid valves 46.

[0056] The translation switching mechanism includes a slide groove 54 on both sides of the housing 1. A slider 55 is slidably connected inside the slide groove 54. A motor 56 is fixed inside one of the sliders 55. A screw 51 is fixed at the output end of the motor 56. One end of the screw 51 is rotatably connected to the other slider 55.

[0057] The shell 1 has two sliding grooves 515 on both sides, and two sliders 514 are slidably connected inside the sliding grooves 515. A screw 513 is rotatably connected between the two sliders 514.

[0058] Both screw 1 51 and screw 3 513 have a pulley 52 fixed at one end, and the two pulleys 52 are externally connected to a belt 53.

[0059] Screw 1 51 and screw 3 513 are respectively threaded inside the two moving blocks 44.

[0060] The start motor 56 drives the screw 51 to rotate. The screw 51 drives the other screw 513 to rotate through the pulley 52 and belt 53, causing the two moving blocks 44 to move along the screw 51 and screw 513. During the movement, the airbag 42, collar 43 and support plate 41 below move, and at the same time drive the moving frame 512, screw 510, motor 59, guide rod 511 and slider 58 above to move. Slider 58 slides on the slide rod 57.

[0061] The downward anti-sticking mechanism includes two sliding rods 57 fixed to the inner wall of the housing 1. A slider 3 58 is sleeved on the outside of the two sliding rods 57. A motor 2 59 is fixed inside the slider 3 58. A screw 2 510 is fixed to the output end of the motor 2 59. A movable frame 512 is threaded on the outside of the screw 2 510. A guide rod 511 is sleeved on the top of the movable frame 512. The top end of the guide rod 511 is fixedly connected to the slider 3 58. The bottom of the movable frame 512 is fixedly connected to two movable blocks 44.

[0062] After all the airbags 42 have been used to press on the limbs, the solenoid valve 46 is opened to release the gas inside the airbags 42. The motor 2 59 is started to drive the screw 2 510 to rotate forward, causing the moving frame 512 to move down along the guide rod 511. The downward movement of the moving frame 512 will push the moving block 44, screw 1 51, screw 3 513, pulley 52, belt 53, slider 1 55, slider 2 514, airbag 42, collar 3 43 and support plate 41 to move down by a specified distance. When slider 1 55 moves down, it slides inside the slide groove 1 54. When slider 2 514 moves down, it slides inside the slide groove 2 515.

[0063] The controller 24 is electrically connected to motor 1 56, motor 2 59, solenoid valve 46 and air pump 45 respectively.

[0064] Working principle:

[0065] First, attach multiple electrode pads 23 to the limb, then the limb enters through the first collar 31, then enters the interior of the third collar 43 and the airbag 42, and then exits through the second collar 32;

[0066] Then controller 24 starts the rehabilitation program;

[0067] The controller 24 controls multiple air pumps 45 to operate sequentially, causing multiple air bags 42 to inflate sequentially, gradually increasing pressure from the distal end to the proximal end, guiding the lymph fluid to flow in one direction and avoiding backflow. Through mechanical compression, the accumulated lymph fluid is pushed back into the blood circulation, reducing tissue swelling, promoting lymphatic return, improving local circulation, reducing the risk of fibrosis or infection caused by long-term edema, and preventing complications.

[0068] When the air bladder 42 inflates, the pressure applied to the limb varies, with greater pressure in the central area and less pressure at the edges, which can easily lead to uneven pressure. To effectively promote lymphatic circulation, it is necessary to ensure that the overall pressure applied to the limb remains uniform.

[0069] After all the airbags 42 have been used to press on the limbs, the solenoid valve 46 is opened to release the gas inside the airbags 42. The motor 2 59 is started to drive the screw 2 510 to rotate forward, causing the moving frame 512 to move down along the guide rod 511. The downward movement of the moving frame 512 will push the moving block 44, screw 1 51, screw 3 513, pulley 52, belt 53, slider 1 55, slider 2 514, airbag 42, collar 3 43 and support plate 41 to move down by a specified distance. When slider 1 55 moves down, it slides inside the slide groove 1 54. When slider 2 514 moves down, it slides inside the slide groove 2 515.

[0070] Because the muscles of the limbs will droop and fit excessively against the inner wall of the bottom of the airbag 42, when the airbag 42 moves down, the contact area between its inner wall and the skin will decrease. This will prevent the skin from rubbing due to excessive contact during movement, which will not only affect the service life of the airbag 42, but also cause discomfort to the patient.

[0071] Then, start motor 1 56 to drive screw 1 51 to rotate. Screw 1 51 drives another screw 3 513 to rotate through pulley 52 and belt 53, so that the two moving blocks 44 move along screw 1 51 and screw 3 513. During the movement, the airbag 42, collar 3 43 and support plate 41 below move, and at the same time drive the moving frame 512, screw 2 510, motor 2 59, guide rod 511 and slider 3 58 above to move. Slider 3 58 slides on slide rod 57.

[0072] Then the controller 24 controls multiple air pumps 45 to operate in sequence, causing multiple airbags 42 to inflate in sequence, gradually increasing pressure from the far end to the near end;

[0073] Repeat the above steps in a circular motion to apply even pressure to the limbs, ensuring uniform force distribution and effectively promoting lymphatic circulation.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
