Description

An ankle rehabilitation training device for gout patients Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to an ankle rehabilitation training device for gout patients. Background Technology

[0002] Gout is a recurrent inflammatory disease caused by increased purine biosynthesis and metabolism, excessive uric acid production, or poor uric acid excretion, leading to elevated blood uric acid levels and the deposition of urate crystals in the synovial membrane, bursae, cartilage, and other tissues of the joints. Since gout can cause pain, swelling, and inflammation in the ankle, affecting patients' daily life and walking function, rehabilitation training for the ankle is necessary to help patients restore normal ankle function, reduce pain, and prevent further deterioration of the condition.

[0003] Existing ankle rehabilitation training equipment for gout patients typically consists of a support bar, elastic ropes, a placement board, and straps. Patients place their feet on the placement board and secure them with straps, then twist their feet in multiple directions (front, back, left, and right) while using the elastic ropes to swing them back and forth for ankle rehabilitation training. Since each gout patient's situation may differ during ankle rehabilitation training, the required force varies. However, the fixed length of the elastic ropes in current gout patient ankle rehabilitation training equipment limits the use of the equipment and makes it inconvenient to adjust the tension of the ropes. Summary of the Invention

[0004] In view of the problems existing in the prior art, since each gout patient may have different conditions when performing ankle rehabilitation training, the amount of force required during training may vary. However, the current ankle rehabilitation training equipment for gout patients is limited in use due to the fixed length of the elastic rope, and it is inconvenient for gout patients to adjust the strength of the rope. The purpose of this invention is to provide an ankle rehabilitation training device for gout patients.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0018] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0019] In the above scheme, by setting an adjustment unit, when the patient needs different strength training, the tension of the elastic rope needs to be adjusted. By rotating the cross block, the first connecting shaft and the drum can be rotated. The rotation of the drum can wind the elastic rope onto its surface or release the elastic rope from its surface, thereby adjusting the tension of the elastic rope to adjust the pulling force of the elastic rope on the placement plate. Before adjustment, the first pull block needs to be raised to pull the limiting post out of the ratchet's tooth groove. During this process, the first spring is compressed and its elastic potential energy increases. After adjustment, the first pull block is released, and the limiting post is re-inserted into the new tooth groove of the ratchet under the action of the first spring, limiting the ratchet and preventing it from rotating arbitrarily.

[0020] By setting up a lifting component, when the patient needs to adjust the height of the device, rotating the screw block can drive the rotating shaft and gear to rotate. The rotation of the gear can drive the rack plate, causing the two second connecting plates to move inward respectively. Since the upper end of the second connecting plate is rotatably connected to the I-beam plate, the second connecting plate can adjust the height of the device when the two moving blocks are close to each other. The higher the placement plate is when the second connecting plate is closer to a vertical state, the easier it is to adjust the height of the device, further improving ankle rehabilitation training for patients of different heights.

[0021] By setting up suction cups, the device is placed on a smooth surface before use, with the support block in contact with the ground. When the patient steps on the device, it exerts downward pressure on the suction cups. The suction cups are completely in contact with the ground through the sealing ring, creating a sealed space between the suction cups, the sealing ring, and the ground. The suction cups can adhere to the ground. During the use of the device, the suction effect of the suction cups prevents the device from shifting. Furthermore, by pressing down on the second connecting rod, the moving plate is moved, compressing the fourth spring. This increases the space above the moving plate and creates negative pressure, allowing air to be drawn from the suction cups through the hollow rod, further enhancing the adhesion between the suction cups and the ground.

[0022] By setting up a U-shaped plate, insertion holes, and insertion rods, when it is necessary to lock the height of the device, pressing down on the U-shaped plate will cause the insertion rod to be inserted into the corresponding insertion hole, thereby locking the gear and achieving the purpose of locking the height of the device. The U-shaped plate can also drive the second connecting rod to move downwards, thereby further enhancing the adsorption between the suction cup and the ground. Attached Figure Description

[0042] As shown in Figures 1 to 10, this embodiment of the invention provides an ankle rehabilitation training device for gout patients, including a main unit 100 and an adjustment unit 200. The main unit 100 includes an I-beam plate 101, with a connecting block 106 rotatably connected to the upper end of the I-beam plate 101. A support rod 102 is rotatably connected to the upper end of the connecting block 106. A fixing rod 107 is symmetrically fixedly connected to the top of the support rod 102. A placement plate 103 is fixedly connected to the top of each fixing rod 107. Straps 104 are fixedly connected to each of the two placement plates 103. The ends of the straps 104 that are close to each other slide through the corresponding placement plates 103. Four elastic ropes 105 are provided between the bottom of the fixing rod 107 and the I-beam plate 101.

[0043] The adjustment unit 200 includes four first connecting plates 201, all of which are disposed at the lower end of the fixed rod 107. A drum 202 is rotatably connected to the lower end of the four first connecting plates 201. The elastic rope 105 is wound around the surface of the drum 202. A circular shell 203 is fixedly connected to the lower end of the first connecting plates 201. The drum 202 is rotatably inserted into the middle of the circular shell 203. A ratchet 204 is fixedly connected to one end of the drum 202. A first connecting shaft 205 is fixedly connected to the outer side of the ratchet 204. A cross block 206 is fixedly connected to the outer side of the first connecting shaft 205.

[0044] By adopting the above technical solution, the cross block 206 is turned, causing the cross block 206 to drive the first connecting shaft 205 to rotate. The first connecting shaft 205 drives the ratchet 204, and the ratchet 204 drives the drum 202 to rotate. The first connecting shaft 205 can be wound onto the surface of the drum 202 or the elastic rope 105 can be released from the surface of the drum 202 to adjust the tension of the elastic rope 105. This allows for adjustment of the tension of the elastic rope 105 on the placement plate 103, adjusting the elastic rope 105 to a force suitable for the patient's rehabilitation training. After adjustment, the patient places their foot on the placement plate 103, and then pulls the strap 104 to fix the foot. By twisting in multiple directions (front, back, left, and right), the patient uses the tension of the elastic rope 105 to swing back and forth to perform rehabilitation training on the ankle.

[0045] As shown in Figures 3 and 4, a hollow column 207 is fixedly connected to the circular shell 203. A first connecting rod 208 is slidably connected to the middle of the hollow column 207. The first connecting rod 208 is slidably inserted into the hollow column 207. A first pull block 209 is fixedly connected to the upper end of the first connecting rod 208. A limiting post 210 is fixedly connected to the lower end of the first connecting rod 208. The limiting post 210 is inserted into the tooth groove of the ratchet 204. A first spring 211 is fixedly connected between the inner top wall of the hollow column 207 and the limiting post 210. The first spring 211 is sleeved on the outside of the first connecting rod 208. A lifting assembly 400 for lifting and lowering the placement plate 103 is provided on the I-beam plate 101.

[0046] When the ratchet 204 needs adjustment, pull the first pull block 209, causing the first pull block 209 to drive the first connecting rod 208. The first connecting rod 208 drives the limiting post 210, causing the first spring 211 to compress. After the limiting post 210 leaves the tooth groove on the ratchet 204, the restriction on the ratchet 204 is released, and the ratchet 204 can then be adjusted. After the adjustment is completed, release the first pull block 209, and the first spring 211 rebounds, causing the limiting post 210 to insert into the tooth groove of the ratchet 204 to re-restrict the ratchet 204 and prevent the strap 104 from rotating freely.

[0047] As shown in Figure 3, T-shaped sliders 212 are symmetrically fixedly connected to the upper and lower ends of the elastic rope 105. The upper end of the first connecting plate 201 is fixedly connected to the T-shaped slider 212. The elastic rope 105 is inserted into the first connecting plate 201. T-shaped grooves 213 that cooperate with the T-shaped slider 212 are provided on both the fixing rod 107 and the I-beam plate 101. A disassembly assembly 300 for disassembling the elastic rope 105 is provided on the upper T-shaped slider 212.

[0048] When the elastic rope 105 needs to be installed, since both the upper and lower ends of the elastic rope 105 are fixedly connected to T-shaped sliders 212, the elastic rope 105 is installed by sliding the two T-shaped sliders 212 into the T-shaped grooves 213 on the I-beam plate 101 and the support rod 102 respectively. When the elastic rope 105 needs to be disassembled, the T-shaped sliders 212 at both the upper and lower ends of the elastic rope 105 can be slid out of the T-shaped grooves 213 to disassemble the elastic rope 105.

[0049] As shown in Figures 3 and 5, the disassembly assembly 300 includes multiple sliding blocks 301. Multiple sliding grooves 302 are symmetrically provided on both the I-beam plate 101 and the support rod 102. The multiple sliding blocks 301 are slidably connected to the inner walls of the corresponding sliding grooves 302. A third spring 303 is fixedly connected between the inner top wall of the sliding groove 302 and the sliding block 301. A second connecting shaft 304 is fixedly connected to the outer side of the sliding block 301. An elliptical groove 305 that cooperates with the second connecting shaft 304 is provided on the support rod 102. A second pull block 306 is fixedly connected to the outer side of the second connecting shaft 304. A pin 307 is fixedly connected to the inner side of the sliding block 301. A slot 308 that cooperates with the pin 307 is provided on the T-shaped slider 212.

[0050] When it is necessary to release the restriction on the T-shaped slider 212, pull the second pull block 306, causing the second pull block 306 to drive the second connecting shaft 304 to slide along the elliptical groove 305. The second connecting shaft 304 drives the sliding block 301 to move, causing the third spring 303 to compress. The sliding block 301 drives the pin 307 to leave the slot 308 on the T-shaped slider 212, thus releasing the restriction on the T-shaped slider 212. When it is necessary to fix the T-shaped slider 212, release the second pull block 306, and the third spring 303 will rebound, causing the sliding block 301 to drive the pin 307 to insert into the slot 308 on the T-shaped slider 212, thus fixing the T-shaped slider 212. This facilitates the installation and removal of the elastic rope 105.

[0051] As shown in Figures 6, 7, and 9, the lifting assembly 400 includes a base plate 401, which is fixedly connected to the outer side of the I-beam 101. A guide rod 402 is fixedly connected to the inner wall of the base plate 401. Moving blocks 403 are symmetrically slidably connected to the guide rod 402. A second connecting plate 404 is symmetrically rotatably connected to both moving blocks 403. The upper end of the second connecting plate 404 is rotatably connected to the I-beam 101. A rack plate 405 is fixedly connected to both moving blocks 403. A rotating shaft 406 is rotatably connected to the guide rod 402. The rotating shaft 406 passes through the guide rod 402. A screw block 407 is fixedly connected to the upper end of the rotating shaft 406. A gear 408 is fixedly connected to the surface of the rotating shaft 406. The gear 408 meshes with the rack plate 405. A U-shaped plate 409 is provided on one side of the rotating shaft 406. The U-shaped plate 409 slides through the base plate 401. A plug rod 410 is fixedly connected to the lower end of the U-shaped plate 409. A plurality of insertion holes 411 are provided on the gear 408 to cooperate with the plug rod 410. A limit rod 412 is slidably connected to the upper end of the base plate 401.

[0052] When the height of the placement plate 103 needs to be adjusted, the screw block 407 is turned, causing the screw block 407 to drive the rotating shaft 406 to rotate. The rotating shaft 406 drives the gear 408, causing the gear 408 to simultaneously drive the two rack plates 405. The two rack plates 405 drive the two moving blocks 403 to move closer to each other. While the moving blocks 403 are moving, they also drive the second connecting plate 404. Since the upper end of the second connecting plate 404 is rotatably connected to the I-beam plate 101, when the moving blocks 403 move closer to each other, the second connecting plate 404 drives the I-beam plate 101 to move closer to each other. The plate 101 moves upward to adjust the height of the placement plate 103. When the placement plate 103 is adjusted to a suitable position, the U-shaped plate 409 is pulled downward so that the insertion rod 410 on the U-shaped plate 409 is inserted into the insertion hole 411 on the gear 408 to restrict the gear 408. Then, the limiting rod 412 is pulled so that the limiting rod 412 slides backward to the upper end of the U-shaped plate 409 to prevent the U-shaped plate 409 from moving upward, thereby completing the height adjustment of the placement plate 103 to accommodate patients of different heights.

[0053] As shown in Figure 8, support blocks 214 are fixedly connected to the four corners at the lower end of the base plate 401. Suction cups 215 are fixedly connected to the inner walls of the multiple support blocks 214. A sealing ring 216 is fixedly connected to the lower end of the suction cups 215. An auxiliary component 500 for driving the suction cups 215 is provided at the lower end of the base plate 401.

[0054] The support block 214 can stabilize the device, and the suction cup 215 and the sealing ring 216 can improve the stability of the device. The suction cup 215 can generate an adsorption force on the ground, making the device less prone to displacement and increasing the tight contact between the suction cup 215 and the ground.

[0055] As shown in Figures 7 and 8, the auxiliary component 500 includes a fixing block 501, which is fixedly connected to the lower end of the base plate 401. A cavity 502 is formed in the middle of the fixing block 501. A moving plate 503 is slidably connected to the inner wall of the cavity 502. Two fourth springs 504 are fixedly connected between the inner bottom wall of the cavity 502 and the moving plate 503. Hollow rods 505 are fixedly connected to each of the multiple suction cups 215. The other ends of the multiple hollow rods 505 are fixedly connected to the fixing block 501. A second connecting rod 506 is fixedly connected to the upper end of the moving plate 503. The second connecting rod 506 slides through the top of the fixing block 501. The upper end of the second connecting rod 506 is fixedly connected to the U-shaped plate 409.

[0056] When it is necessary to improve the stability of the device, pulling down the U-shaped plate 409 can drive the second connecting rod 506, which in turn drives the moving plate 503. When the moving plate 503 moves downward, it can absorb the gas in the sealing ring 216 through the hollow rod 505, thereby compressing the sealing ring 216 and adsorbing it to the ground through the suction cup 215, thereby further improving the stability of the device.

[0057] As shown in Figures 1 and 10, a soft pad 217 is fixedly connected to the upper end of the placement plate 103. A plurality of protrusions 218 are provided on the upper end of the placement plate 103. The plurality of protrusions 218 penetrate the soft pad 217. A heating wire 219 is embedded in the soft pad 217. The heating wire 219 is wound in a curve between the plurality of protrusions 218.

[0058] The pad 217 increases patient comfort during ankle rehabilitation training. The protrusions 218 massage the soles of the feet during training, promoting blood circulation and improving ankle rehabilitation. The heating wire 219 heats the feet during training, especially in winter or cold weather, further enhancing ankle rehabilitation.

[0059] As shown in Figure 10, a second spring 220 is fixedly connected to the lower end of the protrusion 218. A plurality of circular grooves 221 are provided on the placement plate 103. The lower end of the second spring 220 is fixedly connected to the inner bottom wall of the circular groove 221. A plurality of vent holes 222 are provided at the upper end of the protrusion 218. All of the vent holes 222 are circular and arranged in a circumferential manner.

[0060] When patients use the device in the summer, during training, they step on the protrusion 218 and twist in multiple directions (forward, backward, left, and right). The protrusion 218 is stepped into the circular groove 221. When the patient twists, their foot will leave part of the protrusion 218. Under the action of the second spring 220, the protrusion 218 will return to its original position. When the patient steps the protrusion 218 into the circular groove 221 again, the air in the circular groove 221 will be discharged from the vent 222, which can blow air onto the patient's feet and prevent the hot weather from affecting the patient's ankle rehabilitation.

[0061] As shown in Figure 1, a velvet plate 223 is fixedly connected to the inner side of the left strap 104, and a hook plate 224 is fixedly connected to the inner side of the right strap 104. The velvet plate 223 and the hook plate 224 are bonded to each other. Pull-out openings 225 are provided on the strap 104, the hook plate 224 and the pull opening 225.

[0062] The patient places their foot on the placement board 103, then puts their hand through the pull opening 225 and pulls the strap 104 upwards to a suitable position for the patient's foot. The patient then attaches the velvet plate 223 on the inside of the strap 104 to the hook plate 224 to fix the patient's foot, making it easy for the patient to quickly fix their foot.

[0063] The working process provided by this invention is as follows:

[0064] In use, when the height of the placement plate 103 needs to be adjusted, the screw block 407 is turned, causing the screw block 407 to drive the rotating shaft 406 to rotate. The rotating shaft 406 drives the gear 408, causing the gear 408 to simultaneously drive the two rack plates 405. The two rack plates 405 then drive the two moving blocks 403 to move closer to each other. Simultaneously, the moving blocks 403 move, driving the second connecting plate 404. Since the upper end of the second connecting plate 404 is rotatably connected to the I-beam 101, when the moving blocks 403 move closer together, the second connecting plate 404 drives the I-beam 101 to move upwards, adjusting the height of the placement plate 103. When the placement plate 103 is adjusted to a suitable position, the U-shaped plate 409 is pulled downwards, causing... The insertion rod 410 on the U-shaped plate 409 is inserted into the insertion hole 411 on the gear 408 to restrict the gear 408. Then, the limiting rod 412 is pulled, causing the limiting rod 412 to slide backward to the upper end of the U-shaped plate 409, preventing the U-shaped plate 409 from moving upward, thus completing the height adjustment of the placement plate 103. At the same time, pulling the U-shaped plate 409 downward can drive the second connecting rod 506, causing the second connecting rod 506 to drive the moving plate 503. When the moving plate 503 moves downward, it can absorb the gas in the sealing ring 216 through the hollow rod 505, thereby compressing the sealing ring 216. It is then adsorbed to the ground through the suction cup 215, thereby further improving the stability of the device. When the patient needs different During strength training, the tension of the elastic rope 105 needs to be adjusted. Pulling the first pull block 209 causes it to drive the first connecting rod 208, which in turn drives the limiting post 210, compressing the first spring 211. After the limiting post 210 disengages from the toothed groove on the ratchet 204, it releases the ratchet 204. Then, turning the cross block 206 causes it to drive the first connecting shaft 205 to rotate. The first connecting shaft 205 drives the ratchet 204, which in turn drives the drum 202 to rotate. This allows the first connecting shaft 205 to be wound onto the surface of the drum 202 or the elastic rope 105 to be released from the surface of the drum 202, thus adjusting the tension of the elastic rope 105 and achieving the desired elasticity. The tension of the elastic rope 105 on the placement plate 103 is adjusted. When the elastic rope 105 is adjusted to a suitable strength for the patient's rehabilitation training, the first pull block 209 is released, and the first spring 211 rebounds, causing the limiting post 210 to insert into the tooth groove of the ratchet 204 to restrict the ratchet 204 and prevent the strap 104 from rotating freely. Then, the patient places their foot on the placement plate 103, then passes their hand through the pull opening 225 and pulls the strap 104 upwards to a suitable position for the patient's foot. Then, the felt plate 223 on the inner side of the strap 104 is attached to the hook plate 224 to quickly fix the patient's foot. Subsequently, the patient's foot twists in multiple directions (front, back, left, and right), using the tension of the elastic rope 105 to swing back and forth to perform ankle rehabilitation training.When it is necessary to disassemble or replace the elastic cord 105, since both the upper and lower ends of the elastic cord 105 are fixedly connected to T-shaped sliders 212, the second pull block 306 is then pulled, causing the second pull block 306 to drive the second connecting shaft 304 to slide along the elliptical groove 305. The second connecting shaft 304 drives the sliding block 301 to move, causing the third spring 303 to compress. The sliding block 301 drives the pin 307 to disengage from the slot 308 on the T-shaped slider 212, releasing the restriction on the T-shaped slider 212 and freeing the upper and lower ends of the elastic cord 105. The T-shaped slider 212 slides out of the T-shaped groove 213 to disassemble the elastic rope 105. After disassembly, the T-shaped sliders 212 at both ends of the elastic rope 105 to be replaced are slid into the T-shaped grooves 213 on the I-beam plate 101 and the support rod 102 respectively to install the elastic rope 105. Then, the second pull block 306 is released, and the third spring 303 rebounds, causing the sliding block 301 to drive the pin 307 to insert into the slot 308 on the T-shaped slider 212 to fix the T-shaped slider 212, facilitating the installation and disassembly of the elastic rope 105.
