Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training equipment technology, and in particular to a portable ankle joint training device. Background Technology

[0002] With the increasing aging of my country's population and the rise in the number of long-term bedridden patients due to stroke, spinal cord injury, hip / knee replacement surgery, and multiple fractures, clinical studies have shown that long-term bedridden patients are prone to motor dysfunction such as joint range of motion and muscle weakness in various joints of the limbs. As an important joint for bearing weight and maintaining balance, the ankle joint directly affects the patient's upright and walking functions after rehabilitation. Ankle rehabilitation training can effectively improve the ankle joint function of such patients.

[0003] As the only end joint in the human body that bears the triple functions of weight-bearing, shock absorption, and balance in both the sagittal and coronal planes and directly affects a patient's ability to stand and walk after rehabilitation, dysfunction of the ankle joint not only delays the timing of standing, weight transfer, and gait training, but also significantly increases the risk of secondary complications such as falls, pressure sores, and deep vein thrombosis, thus prolonging the average length of hospital stay. Therefore, the concept of early bedside rehabilitation advocates starting ankle pump exercises, joint mobilization, and resistance training as soon as the patient's vital signs stabilize.

[0004] However, existing ankle rehabilitation equipment generally adopts a floor-standing rigid exoskeleton and servo motor solution, which takes up a lot of space and needs to be fixed in the rehabilitation hall. The bottom universal casters have small wheel diameters, no shock absorption, and a high center of gravity, making it difficult to turn in narrow corridors, door sills, and elevator cars, and they are prone to tipping over. They cannot be moved conveniently between beds or wards, causing great inconvenience to users. Utility Model Content

[0037] refer to Figures 1 to 5 A portable ankle joint training device according to a preferred embodiment of the present invention will be described in detail below:

[0038] The portable ankle joint training device includes a housing 10 and a training component 20. The housing 10 has an irregular rectangular shape and forms an installation space 11 inside. The training component 20 includes a support member 21 and a power component 22. The support member 21 is fixedly installed on one side of the housing 10 and is located away from the power component 22. The support member 21 can provide some support for the portable ankle joint training device during rehabilitation training, allowing the rehabilitation personnel to perform training smoothly and thus improving rehabilitation efficiency. The power component 22 is fixedly installed in the installation space 11. The power component 22 includes a motor 221 and a reducer 222. Both the motor 221 and the reducer 222 are fixedly installed in the installation space 11, and the reducer 222 is fixedly connected to the motor 221. An output shaft 2221 is provided on the reducer 222. Both ends of the output shaft 2221 pass through the housing 10 and communicate with the outside of the housing 10, so as to provide stable rotational power or resistance for rehabilitation personnel to exercise their ankle joints and improve the training efficiency of the portable ankle joint training device.

[0039] It is worth mentioning that the housing 10 is also provided with a handle 12, which makes it convenient for rehabilitation personnel to carry and move the portable ankle joint training device, thereby enhancing the mobility of the portable ankle joint training device.

[0040] Specifically, the support member 21 includes a connecting base 211, which is fixedly installed on the housing 10. In this embodiment, the connecting base 211 is U-shaped and has multiple sets of threaded through holes 2111, which facilitates the fixing of the connecting base 211 to the housing 10 with bolts or other fasteners through the multiple sets of threaded through holes 2111. Connecting ears, namely a first connecting ear 212 and a second connecting ear 213, are provided on both sides of the connecting base 211. The first connecting ear 212 and the second connecting ear 213 are symmetrically designed with respect to the connecting base 211, and both the first connecting ear 212 and the second connecting ear 213 are semi-circular arc-shaped.

[0041] Furthermore, the support member 21 also includes a first hinge 214, a first bracket 215, a second hinge 216, and a second bracket 217. One end of the first hinge 214 is rotatably mounted to the first connecting ear 212, and the other end of the first hinge 214 is fixedly connected to the first bracket 215 and is located away from the connecting base 211. One end of the second hinge 216 is rotatably mounted to the second connecting ear 213, and the other end of the second hinge 216 is fixedly connected to the second bracket 217. The first hinge 214, the first bracket 215, the second hinge 216, and the second bracket 217 are symmetrically designed about the connecting base 211. With this design, the first bracket 215 and the second bracket 217 can provide good support for the housing 10.

[0042] Specifically, mounting holes are provided in both the first connecting ear 212 and the second connecting ear 213 to facilitate the rotatable mounting of the first hinge 214 and the second hinge 216 on the connecting base 211, thereby enabling the opening and closing of the first bracket 215 and the second bracket 217.

[0043] Furthermore, a first limiting groove 218 and a second limiting groove 219 are provided at the arc-shaped cross-section of the first connecting ear 212 and the second connecting ear 213. The first limiting groove 218 and the second limiting groove 219 are open, and the preset positions of the first limiting groove 218 and the second limiting groove 219 are set at a vertical angle, which facilitates the limiting and fixing of the first bracket 215 and the second bracket 217.

[0044] Specifically, both the first hinge 214 and the second hinge 216 are provided with limiting shafts and switch pieces. The switch pieces are fixedly connected to the limiting shafts, and the limiting shafts can be moved through the switch pieces. The limiting shafts are adapted to the first limiting groove 218 and the second limiting groove 219. With this configuration, when rehabilitation personnel use the portable ankle joint training device for exercise, they can move the switch piece. At this time, the limiting shafts will move away from the first limiting groove 218. Then, the first bracket 215 and the second bracket 217 will be rotated away from the housing 10 until the first bracket 215 and the second bracket 217 are in a horizontal line. At this time, the limiting shafts of the first bracket 215 and the second bracket 217 will be locked into the second limiting groove 219. At this time, the opening and closing angle of the first bracket 215 and the second bracket 217 will be locked, which can improve the stability of the support assembly 40.

[0045] When the portable ankle joint training device is no longer in use, the switch is flipped, at which point the limiting shaft moves away from the second limiting groove 219. Then, the first bracket 215 and the second bracket 217 are rotated toward the housing 10 until they are in contact with the side of the housing 10. At this point, the limiting shafts of the first bracket 215 and the second bracket 217 are precisely engaged in the first limiting groove 218, which can prevent the first bracket 215 and the second bracket 217 from being accidentally opened, thus improving the portability and flexibility of the portable ankle joint training device.

[0046] In this embodiment, the rehabilitation component 23 is provided in two sets, and the two sets of rehabilitation components 23 are respectively fixed at both ends of the output shaft 2221 of the reducer 222. This design allows rehabilitation personnel to perform rehabilitation training on both feet at the same time, thus broadening the application scenarios of the portable ankle joint training device.

[0047] Specifically, the rehabilitation component 23 includes a connecting end 231, a first guide rail 232, a first slider 233, a first knob 234, and an adapter 235. The connecting end 231 is fixedly mounted on the output shaft 2221, and the first guide rail 232 is fixedly mounted on the connecting end 231. The first guide rail 232 is set at a perpendicular angle to the output shaft 2221 to prevent interference between the housing 10 and the rehabilitation component 23 during rehabilitation training, thus preventing secondary injury to the rehabilitation personnel. A first slide rail 23 is provided on the first guide rail 232. 21, and the first slide 2321 is adapted to the first slider 233. One end of the first slider 233 is slidably installed in the first slide 2321 of the first guide rail 232, and the other end of the first slider 233 is fixedly connected to the adapter 235. The first knob 234 is rotatably installed on the adapter 235. With this setting, the position of the first slider 233 in the first slide 2321 can be adjusted by turning the first knob 234 according to the leg length of the rehabilitation person, thereby adjusting the vertical height of the rehabilitation piece 23.

[0048] Furthermore, the rehabilitation component 23 also includes a second slider 236, a second knob 237, a second guide rail 238, and a pedal 239. One end of the second slider 236 is fixedly mounted on the adapter 235, and the mounting angle of the second slider 236 is perpendicular to the adapter 235. The second knob 237 is rotatably mounted on the second slider 236, and the second knob 237 is mounted on the side near the second guide rail 238. A second slide rail 2381 is provided on the second guide rail 238. The other end of the second slider 236 is slidably mounted. Within the second slide rail 2381 of the second guide rail 238, the pedal 239 is fixedly mounted on the second guide rail 238, and the pedal 239 is mounted on the side away from the second slide rail 2381. The side of the pedal 239 closest to the second slider 236 has an arc-shaped protrusion 2391 designed according to ergonomics, and this protrusion 2391 is perpendicular to the pedal 239, allowing it to fully conform to the rehabilitation user's foot, thus forming a storage space. This provides good coverage for the ankle, preventing the foot from slipping off the pedal during rehabilitation training and causing secondary ankle injury. With this configuration, the movement position of the second slider 236 in the second slide rail 2381 can be adjusted via the second knob 237, thereby adjusting the horizontal length of the rehabilitation component 23.

[0049] Specifically, the portable ankle joint training device also includes a control component 30, which is fixedly installed on the housing 10 and electrically connected to the motor 221. The control component 30 includes a control panel 31, which is fixedly installed on the housing 10. This allows rehabilitation personnel to easily set the power, speed and other exercise parameters of rehabilitation training through the control panel 31, greatly improving the user experience.

[0050] Furthermore, the portable ankle joint training device also includes a fixing component 40, which further includes a strap 41 and a strap pressure plate 42. The strap 41 and the strap pressure plate 42 are both fixedly installed in the storage space of the pedal 239. The strap 41 can completely cover the foot of the rehabilitation personnel, thereby fixing the ankle. The strap pressure plate 42 can effectively shape and fix the strap 41, preventing the strap 41 from exerting excessive pressure on the sole of the rehabilitation personnel's foot and improving wearing comfort. At the same time, the strap 41 can also fix the instep of the rehabilitation personnel, improving the safety of using the portable ankle joint training device.

[0051] Furthermore, the strap 41 is entirely made of Velcro with a rough surface, which can be effectively attached to the hook side of Velcro, making it convenient for rehabilitation personnel to quickly wear the portable ankle joint training device.

[0052] With the above setup, when rehabilitation personnel use the portable ankle joint training device, they can place the device on a bed or in a suitable location, input training parameters through the control panel, turn on the support, adjust the position of the device according to their own height, place their foot on the pedal, secure it with the straps, and turn on the power. The device will then move under the drive of the power unit, thereby performing rehabilitation training on the ankle joint, greatly improving the convenience for rehabilitation personnel to use the portable ankle joint training device.

[0053] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
