Description

Technical Field

[0001] The present invention belongs to the technical field of cardiovascular medicine rehabilitation, specifically a rehabilitation training device. Background Art

[0002] Cardiovascular medicine is a clinical department specializing in the diagnosis and treatment of heart and blood vessel diseases. In order to promote the recovery of heart function, rehabilitation training devices are often used to conduct rehabilitation training on patients, accelerating recovery through exercise training and reducing the risk of complications.

[0003] Existing cardiovascular medicine rehabilitation training devices are divided into various types, including upper limb and lower limb training devices. When cardiovascular disease patients use a pedal - type training device to conduct rehabilitation training on the lower limbs, it can help patients complete safe and controllable lower limb movements, promote blood circulation in the lower limbs, and avoid muscle disuse atrophy at the same time.

[0004] When the above - mentioned pedal - type rehabilitation training is in use, the connection between the patient's feet and the pedals is generally adjusted manually by straps. To prevent the feet from slipping off the pedals, patients often adopt compensatory postures such as tiptoeing or shrinking the legs to drive the pedals to rotate. Compensatory postures disrupt the neuromuscular control chain and exacerbate joint stress concentration, thereby reducing the rehabilitation training effect. In addition, due to the uncertainty of the user's foot size, the time for adjusting the straps increases, resulting in a problem of reduced training efficiency. Summary of the Invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. For the rehabilitation training device described in the present invention, by providing a support plate and a placement groove, when the user needs to use the rehabilitation device for training, place the toe part inside the placement groove and the foot plate part on the support plate, and then drive the pedal to rotate to perform training operations on the lower limbs. By fixing the toe part through the placement groove and supporting the foot plate part by the support plate, there is no need to manually adjust the straps, reducing the operation time for fixing the feet, thereby improving the training efficiency.

[0018] 2. In the rehabilitation training device of the present invention, by providing a push plate assembly and a support plate, when the user places the foot on the support plate, the foot presses down on the support plate, causing the support plate below the foot to descend. After the support plate descends, the pushing assembly pushes the remaining support plates that have not descended to slide horizontally, causing multiple support plates to move and abut against the instep of the user's foot for a limiting operation. This device can automatically perform a limiting operation on the rear of the user's foot according to the size of the user's foot, without manually adjusting the straps, reducing the operation time for fixing the foot, thereby improving the training efficiency. At the same time, it can maintain the natural posture of the foot, prevent the foot from sliding off the pedal, and avoid the user adopting compensatory postures such as tiptoeing or shrinking the legs, which weakens the rehabilitation training effect.

[0019] 3. In the rehabilitation training device of the present invention, by providing a driving assembly, a support assembly, and a support plate, when the user finishes exercising, the pedal can be driven to slide horizontally on the support assembly. Subsequently, the user uses the foot to drive the pedal to rotate reciprocally on the support assembly. At this time, the driving assembly can push the support plate to drive the massage protrusions to slide horizontally reciprocally to massage the sole of the user's foot. Through the horizontal sliding of the massage protrusions, the plantar blood vessels can be mechanically squeezed, enhancing the blood return efficiency. At the same time, it can relieve the stiffness of the muscles after exercise, and massaging the foot not only avoids the excessive cardiorespiratory load caused by excessive active movement but also stimulates acupoints to improve the rehabilitation training effect.

[0039] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0040] Embodiment 1

[0041] As Figures 1 to 10As shown in the figure, the rehabilitation training device described in this embodiment includes a base assembly 10. A support assembly 30 is provided on the base assembly 10, and a foot pedal assembly 20 is provided on the support assembly 30. The foot pedal assembly 20 includes a pedal 21. A placement groove 211 is provided on the pedal 21. A plurality of support plates 23 are slidably connected inside the pedal 21. A plurality of massage protrusions 231 are provided on each support plate 23. A pushing assembly 22 and a driving assembly 25 are provided inside the pedal 21. When the user steps on the support plate 23 with their foot and it descends, then according to the foot size, the driving assembly 25 is used to push the support plates 23 that have not been stepped on to move, so that the support plates 23 limit the rear of the foot. Then the pedal 21 is driven to slide and rotate on the foot pedal assembly 20. Subsequently, the driving assembly 25 drives the support plates 23 and the massage protrusions 231 to slide horizontally under the foot for massage treatment;

[0042] As Figure 1 shown in the figure, the base assembly 10 includes a support base 11. A seat cushion 12 is fixedly connected to the support base 11 by a screw. A handle 13 is fixedly connected to the support base 11. A rotating rod 14 is rotatably connected inside the support base 11. One end of the rotating rod 14 is fixedly connected to one end of a fixed rod 31.

[0043] As Figures 2 to 5 shown in the figure, a connecting frame 232 is provided on the lower surface of the support plate 23. Fixed frames 24 are slidably connected to both sides of the connecting frame 232. The fixed frames 24 are fixedly connected inside the pedal 21. A horizontal groove 242 is provided inside the fixed frame 24. A vertical groove 241 is provided inside the horizontal groove 242. Both the vertical groove 241 and the horizontal groove 242 are slidably connected to one side of the connecting frame 232.

[0044] As Figure 5 and Figure 7 shown in the figure, a magnetic plate 243 is fixedly connected to the upper surface of the fixed frame 24. A magnetic block 233 is fixedly connected inside the connecting frame 232. The magnetism between the magnetic block 233 and the magnetic plate 243 attracts each other. A plug rod 234 is fixedly connected below the connecting frame 232.

[0045] Specifically, existing cardiovascular medicine rehabilitation training devices are divided into various types, including upper limb and lower limb training devices. When cardiovascular disease patients use a pedal - type training device to perform rehabilitation training on the lower limbs, in order to prevent the feet from sliding off the pedal 21, patients may adopt compensatory postures such as standing on tiptoe or shrinking the legs, weakening the rehabilitation training effect. Therefore, medical staff need to fix the user's feet and the pedal 21. Generally, a manual - adjustment strap is used for connection. Due to the uncertainty of the user's foot size, the time for adjusting the strap increases, thus causing the problem of reduced training efficiency;

[0046] To solve the problems raised above, the present device is used as follows: First, adjust the height of the seat cushion 12, then sit on the seat cushion 12, place the hand on the grip 13 and hold it, then place the foot on the pedal 21, with the toes inside the placement groove 211, and the sole of the foot in contact with the support plate 23. The sole of the foot exerts a downward pressure on the support plate 23 in contact with it, causing the support plate 23 in contact with the sole of the foot to slide inward towards the pedal 21. The support plate 23 drives the lower connecting frame 232 to slide downward in the vertical groove 241 of the fixed plate, causing the connecting frame 232 to drive the magnet 233 away from the magnetic plate 243. Under normal conditions, the magnet 233 and the magnetic plate 243 are magnetically adsorbed, causing the connecting frame 232 to be at the junction between the vertical groove 241 and the horizontal groove 242. At this time, there is a dislocation between the downward-moving support plate 23 and the support plate 23 not in contact with the sole of the foot, causing the pushing component 22 to work. The pushing component 22 pushes the non-contact support plate 23 towards the heel direction. The non-contact support plate 23 drives the connecting frame 232 to slide in the horizontal groove 242 and stop at the heel, enabling the foot to be limited. At this time, the user can drive the pedal 21 to rotate for lower limb rehabilitation training.

[0047] The present device can automatically limit the rear of the user's foot according to the size of the foot, without manual adjustment of the strap, reducing the operation time for fixing the foot, thus improving the training efficiency. At the same time, it can maintain the natural posture of the foot, prevent the foot from sliding off the pedal 21, and avoid the patient adopting compensatory postures such as tiptoeing or shrinking the legs, which weakens the rehabilitation training effect.

[0048] As Figure 9 and Figure 10 shown, the pushing component 22 includes a bracket 221 fixedly connected inside the pedal 21. A push plate 222 is slidably connected inside the bracket 221. A first spring 223 is fixedly connected between the push plate 222 and the pedal 21. A limit block 224 is slidably connected inside the bracket 221 through a second spring 225. Several limit grooves 226 are provided below the push plate 222. The limit block 224 and the limit grooves 226 have one-way limiting. The driving component 25 includes a slide bar 252 fixedly connected inside the pedal 21. A moving plate 251 is slidably connected on the slide bar 252 through a third spring 253. Several jacks 255 are provided inside the moving plate 251. The size of the jacks 255 matches the size of the insertion rods 234.

[0049] Specifically, the pushing component 22 is used as follows: When there is a dislocation between the downward-moving support plate 23 and the support plate 23 that does not contact the sole of the foot, the first spring 223 drives the push plate 222 to move. The push plate 222 pushes the support plate 23 to slide, so that the support plate 23 performs a limiting operation on the foot. At the same time, when the push plate 222 drives the limiting groove 226 to move towards the heel direction, the limiting groove 226 squeezes the limiting block 224 to move downward at this time. When the limiting block 224 moves downward, it squeezes the second spring 225, and then drives the limiting block 224 to reset into the limiting groove 226 through the second spring 225 and cooperate with the limiting groove 226, so that the push plate 222 performs a limiting operation;

[0050] After use, the medical staff pulls the limiting block 224 downward, and the limiting block 224 moves away from the limiting groove 226. Subsequently, the user's foot moves towards the side of the push plate 222, and the foot pushes the plurality of non-contact support plates 23 to slide towards the side of the push plate 222. At the same time, the toe end disengages from the placement groove 211. The plurality of non-contact support plates 23 push the push plate 222 to squeeze the first spring 223 to reset. When the push plate 222 is reset, the user lifts the foot, and the magnetic plate 243 adsorbs the magnetic block 233, so that the connecting frame 232 drives the support plate 23 to slide towards the outside of the pedal 21. The magnetic plate 243 contacts and adsorbs the magnetic block 233. At the same time, the moving limiting plate resets to the initial position and squeezes and limits the non-contact limiting plate, so that each support plate 23 is kept in the normal position. Finally, the medical staff releases the limiting block 224, and the limiting block 224 contacts the limiting groove 226, and the foot can be disengaged.

[0051] Embodiment 2

[0052] As Figures 6 to 8 shown, compared with Embodiment 1, another implementation manner of the present invention is: The driving component 25 includes a sliding rod 252 fixedly connected inside the pedal 21. A moving plate 251 is slidably connected to the sliding rod 252 through a third spring 253. A plurality of jacks 255 are provided inside the moving plate 251. The size of the jacks 255 matches the size of the insertion rods 234. A limiting rod 254 is fixedly connected to the lower surface of the moving plate 251. One end of the limiting rod 254 is arc-shaped. The supporting component 30 includes a fixed rod 31. The fixed rod 31 is slidably connected to the pedal 21. A torsion spring 33 is fixedly connected between the fixed plate and the pedal 21. A chute 32 is provided on the fixed rod 31. The chute 32 is slidably connected to one end of the limiting rod 254. The chute 32 includes a horizontal section 321, and an inclined section 322 is provided on one side of the horizontal section 321.

[0053] Specifically, when the user finishes training, the sole muscles become stiff due to long-term exercise, resulting in the accumulation of metabolic wastes, delaying recovery, and prolonging the muscle recovery time, increasing the problem of muscle soreness;

[0054] To avoid the above problems, the present device is used as follows: when the support plate 23 drives the connecting frame 232 to descend, the connecting frame 232 drives the insertion rod 234 to descend, and the insertion rod 234 enters the insertion hole 255 inside the moving plate 251. After use, the user can drive the pedal 21 to slide horizontally on the fixed rod 31 and stretch the torsion spring 33. The pedal 21 pushes the moving plate 251 to slide through the third spring 253. The moving plate 251 drives the limiting rod 254 to slide in the chute 32. At this time, the limiting rod 254 slides in the horizontal section 321 of the chute 32. After the pedal 21 slides to one end of the fixed rod 31, the user drives the pedal 21 to rotate with the foot. The pedal 21 drives the moving plate 251 to rotate. The moving plate 251 drives the limiting rod 254 to rotate. The limiting rod 254 slides from the horizontal section 321 to the inclined section 322, so that the limiting rod 254 is squeezed and drives the moving plate 251 to slide. The moving plate 251 drives the insertion rod 234 to slide. The insertion rod 234 drives the support plate 23 at one end of the connecting frame 232 to slide. The support plate 23 drives the massage protrusion 231 to slide horizontally, so that the massage protrusion 231 massages the sole of the foot.

[0055] Through the horizontal sliding of the massage protrusion 231, the present device can mechanically squeeze the blood vessels on the sole of the foot, enhance the blood return efficiency, and at the same time relieve the stiffness of the muscles after exercise. Moreover, massaging the feet can not only avoid the cardiopulmonary load caused by excessive active exercise, but also stimulate acupoints to improve the rehabilitation training effect.

[0056] Working principle: First, use it to adjust the height of the seat cushion 12. Then, sit on the seat cushion 12, place your hands on the grips 13 and hold them. Next, place your feet on the pedals 21, with your toes inside the placement grooves 211, and the soles of your feet in contact with the support plates 23. The soles of the feet exert a downward pressure on the support plates 23 in contact with them, causing the support plates 23 in contact with the soles of the feet to slide inward on the pedals 21. The support plates 23 drive the connecting frames 232 below to slide downward in the vertical grooves 241 of the fixed plates, causing the connecting frames 232 to drive the magnetic blocks 233 away from the magnetic plates 243. Under normal conditions, the magnetic blocks 233 and the magnetic plates 243 are magnetically adsorbed, causing the connecting frames 232 to be at the junction between the vertical grooves 241 and the horizontal grooves 242. When there is a dislocation between the downward-moving support plates 23 and the support plates 23 not in contact with the soles of the feet, the first spring 223 drives the push plate 222 to move. The push plate 222 pushes the support plates 23 to slide, enabling the support plates 23 to limit the movement of the feet. At the same time, when the push plate 222 drives the limit groove 226 to move towards the heel direction, the limit groove 226 squeezes the limit block 224 to move downward. When the limit block 224 moves downward, it squeezes the second spring 225. Subsequently, the second spring 225 drives the limit block 224 to reset into the limit groove 226 and cooperate with the limit groove 226, making it difficult for the push plate 222 to reset and slide, thus enabling the feet to be limited. At this time, the user can drive the pedals 21 to rotate for lower limb rehabilitation training;

[0057] When the support plates 23 drive the connecting frames 232 to descend, the connecting frames 232 drive the insertion rods 234 to descend. The insertion rods 234 enter the insertion holes 255 inside the moving plates 251. When the use is completed, the user can drive the pedals 21 to slide horizontally on the fixed rods 31 and stretch the torsion springs 33. The pedals 21 push the moving plates 251 through the third springs 253. The moving plates 251 drive the limit rods 254 to slide in the sliding grooves 32. At this time, the limit rods 254 slide in the horizontal sections 321 of the sliding grooves 32. When the pedals 21 slide to one end of the fixed rods 31, the user uses their feet to drive the pedals 21 to rotate. The pedals 21 drive the moving plates 251 to rotate. The moving plates 251 drive the limit rods 254 to rotate. The limit rods 254 slide from the horizontal sections 321 to the inclined sections 322, causing the limit rods 254 to be squeezed and driving the moving plates 251 to slide. The moving plates 251 drive the insertion rods 234 to slide. The insertion rods 234 drive the support plates 23 at one end of the connecting frames 232 to slide. The support plates 23 drive the massage protrusions 231 to slide horizontally, enabling the massage protrusions 231 to massage the soles of the feet;

[0058] After use, the medical staff pulls the limit block 224 downward. The limit block 224 moves away from the limit groove 226. Then, the user's foot moves towards one side of the push plate 222. The foot pushes multiple uncontacted support plates 23 to slide towards one side of the push plate 222. At the same time, the toe part disengages from the placement groove 211. The multiple uncontacted support plates 23 push the push plate 222 to squeeze the first spring 223 for reset. After the push plate 222 is reset, the user lifts the foot. The magnetic plate 243 adsorbs the magnetic block 233, so that the connecting frame 232 drives the support plate 23 to slide towards the outside of the pedal 21. The magnetic plate 243 and the magnetic block 233 come into contact and adsorb. At the same time, the moving limit plate resets to the initial position and squeezes and limits the uncontacted limit plate, so that each support plate 23 remains in the normal position. Finally, the medical staff releases the limit block 224, and the limit block 224 contacts the limit groove 226, and the foot can be disengaged.
