Abstract
Description
Technical Field
[0001] This utility model relates to the field of ankle pump-assisted training technology, and more specifically, to an ankle pump exercise assistive training device. Background Technology
[0002] Ankle pump exercises are a type of lower limb functional exercise that promotes blood circulation and lymphatic flow through ankle flexion, extension, and circumduction movements. They play a crucial role in the functional recovery of patients who are bedridden for extended periods or have undergone lower limb surgery.
[0003] The main benefits of ankle pump exercises include: 1. Accelerating blood circulation: Preventing deep vein thrombosis in the legs caused by prolonged bed rest. 2. Promoting edema absorption: Blood circulation helps remove waste and transport nutrients, promoting edema absorption and reducing swelling. 3. Preventing thrombosis: Through rhythmic contractions of the gastrocnemius muscle during ankle pump exercises, the speed of venous blood flow within the gastrocnemius muscle is increased, reducing venous blood stasis and overcoming the risk of deep vein thrombosis caused by slow blood flow due to prolonged bed rest. 4. Enhancing muscle strength and preventing muscle atrophy: Ankle pump exercises help enhance muscle strength, prevent muscle atrophy, and improve limb function reconstruction.
[0004] Current ankle pump exercise devices (ankle pump assistive trainers) typically only have simple ankle flexion and extension exercises. Ankle pump exercise assistive trainers that have ankle circumduction exercises are usually too large or too expensive, while simple ankle pump exercise devices usually cannot properly train ankle flexion and extension exercises.
[0005] Simple ankle pump assist trainers typically involve performing ankle flexion and extension exercises with the entire foot. The key to ankle flexion and extension exercises is to forcefully flex and point the toes, and these two steps need to be held for a certain period of time before relaxing. Currently, these two movements cannot be achieved with simple ankle pump assist trainers. Utility Model Content
[0006] The purpose of this invention is to provide an ankle pump exercise assistive training device, a training device that can actively train a patient's ankle pump.
[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an ankle pump exercise assistive training device, comprising a support device, a fixing device, and a driving device;
[0008] The fixing device includes a thigh fixing sleeve fixedly mounted on the bearing device, a calf fixing sleeve fixedly mounted on the bearing device, a placement plate movably mounted on the bearing device, and a fixing plate hinged to the placement plate on the side away from the bearing device; the thigh fixing sleeve is hinged to one end of the calf fixing sleeve, and the placement plate is spaced apart at the end of the calf fixing sleeve away from the thigh fixing sleeve;
[0009] The driving device is mounted on the support device and includes a rocking drive assembly for rocking the placement plate and a bending drive assembly for rotating the fixed plate. The bending drive assembly includes a telescopic motor fixedly mounted on the back of the placement plate. The output end of the telescopic motor is provided with a flexible shaft guide rod. The end of the flexible shaft guide rod away from the telescopic motor is fixedly connected to the fixed plate through a fixing block. The flexible shaft guide rod is also provided with a guide ring for guiding the flexible shaft guide rod. The guide ring is fixedly mounted on the placement plate and located near the hinge point between the fixed plate and the placement plate.
[0010] The flexible shaft guide rod can be extended and retracted by the telescopic motor. One end of the flexible shaft guide rod is fixed to the fixed plate. When the guide rod is squeezed by the telescopic motor, it expands and forces the fixed plate to bend to the other side. In order to better guide the bending effect, a guide ring is set on the placement plate to further improve the guiding effect and prevent excessive bending and damage from bending to the left or right.
[0011] The present invention is further configured such that: the swing assembly includes a first motor fixedly mounted on the bearing device, a steering frame for horizontal steering is provided on the output end of the first motor, a steering ring for vertical steering is rotatably provided on the inner side of the steering frame, and the outer wall of the steering ring away from the steering frame is fixedly connected to the end of the placement plate away from the fixed plate by a connecting column.
[0012] The swing assembly also includes a second motor disposed next to the first motor. The output end of the second motor is provided with a first steering link for controlling the direction of rotation. The end of the first steering link away from the second motor is provided with a second steering link for transmitting force. The end of the second steering link away from the first steering link is mounted on the connecting column to control the rotation of the placement plate.
[0013] The horizontal steering of the steering frame creates a slight left-right rotation of the foot. The steering ring inside the steering frame rotates vertically in conjunction with the frame. As is well known, rotation in two directions can create a spherical disturbance effect, resulting in a 360° toe rotation. To control the force of rotation and the traction and guiding effects after rotation, the position of the connecting column is limited by the second motor, the first steering linkage, and the second steering linkage. Only a slight movement is needed to create a 360° rotation at the toe. The second motor provides the control force to achieve the ankle joint rotation effect. The holding time can be adjusted by changing the motor's rotation speed, and the holding force can be gradually increased.
[0014] The present invention is further configured such that: the first motor is a disc-shaped servo motor, the steering frame is a U-shaped structure, and the outer radial side of the steering ring is connected to the two end shafts of the steering frame.
[0015] The disc-shaped servo motor reduces the height, making it more physiologically appropriate for patients to use, and the U-shaped steering frame makes it easier to install and fix.
[0016] The present invention is further configured such that the first steering link and the second steering link are right-angle structures.
[0017] The right-angle structure ensures that the steering frame and steering ring will not be disturbed during steering adjustments, while the second steering link is mainly designed to extend the first steering link, thereby extending the control range.
[0018] The present invention is further configured such that: the second motor is fixedly mounted on the side of the first motor by a mounting plate fixedly mounted on the bearing device, and the axis of the output end of the second motor is collinear with the hinge axis of the steering ring and the steering frame;
[0019] The hinge axis of the hinge end of the first steering link and the second steering link is collinear with the axis of the steering ring.
[0020] By aligning the axis of the second motor with the same line, the rotation direction of the motor can be better corrected.
[0021] The present invention is further configured such that: the placement plate and the fixing plate are hinged together to form a full human foot structure, and the hinge point of the placement plate and the fixing plate is located between the toes and the sole of the foot.
[0022] When combined to form a structure that covers the entire foot, it achieves an ergonomic effect.
[0023] The present invention is further configured such that: the front of the fixing plate is provided with a fixing strap for fixing the foot, and the front of the placement plate is provided with a surrounding plate for foot limiting, and the surrounding plate can surround the three sides of the placement plate away from the fixing plate to form a limiting structure.
[0024] The toes are secured by the straps, which helps to straighten the foot, while the side panels further restrict the direction of foot movement.
[0025] The present invention is further configured such that: the supporting device includes a decorative box, the decorative box having a cuboid box-shaped structure with an opening on the top surface extending to one end, and the decorative box having a plurality of fixing platforms for supporting the lower leg fixing sleeve.
[0026] The decorative box facilitates the placement and movement of the equipment, and a fixed platform is added to keep the lower legs relatively fixed.
[0027] The present invention is further configured such that: the thigh fixing sleeve is a soft, open sleeve structure that can wrap around the thigh, and a fixing ring is provided on the outer side of the thigh fixing sleeve away from the thigh.
[0028] Setting the thigh position to be fixed is to ensure the fixation effect, and also to relatively loosen the calf position, so as to ensure that the calf and thigh form a relative curvature, which is more in line with the actual calf elevation effect in operation.
[0029] In summary, this utility model has the following beneficial effects: the telescopic motor enables the flexible shaft guide rod to extend and retract, and one end of the flexible shaft guide rod is fixed to the fixed plate. When the flexible shaft guide rod is squeezed by the telescopic motor, it expands, forcing the fixed plate to bend to the other side. In order to better guide the bending effect, a guide ring is set on the placement plate, which can further improve the guiding effect and prevent excessive bending and damage from bending to the left or right.
[0030] The horizontal steering of the steering frame creates a slight left-right rotation of the foot. The steering ring inside the steering frame rotates vertically in conjunction with the frame. As is well known, rotation in two directions can create a spherical disturbance effect, resulting in a 360° toe rotation. To control the force of rotation and the traction and guiding effects after rotation, the position of the connecting column is limited by the second motor, the first steering linkage, and the second steering linkage. Only a slight movement is needed to create a 360° rotation at the toe. The second motor provides the control force to achieve the ankle joint rotation effect. The holding time can be adjusted by changing the motor's rotation speed, and the holding force can be gradually increased. Attached Figure Description

[0049] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0050] The following is in conjunction with the appendix Figures 1-7 The present invention will be described in further detail below.
[0051] Example
[0052] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, an ankle pump exercise assistive training device includes a support device 1, a fixing device 2, and a driving device 3.
[0053] The supporting device 1 includes a decorative box 11, which is a rectangular box-shaped structure with an opening on the top extending to one end. The decorative box 11 is provided with several fixing platforms 12 for supporting the lower leg fixing sleeve 22. The decorative box 11 facilitates the placement and movement of the device. In order to keep the lower leg relatively fixed, the fixing platforms 12 are added.
[0054] The fixing device 2 includes a thigh fixing sleeve 21 fixedly mounted on the bearing device 1, a calf fixing sleeve 22 fixedly mounted on the bearing device 1, a placement plate 23 movably mounted on the bearing device 1, and a fixing plate 24 hinged to the side of the placement plate 23 away from the bearing device 1; the thigh fixing sleeve 21 is hinged to one end of the calf fixing sleeve 22, and the placement plate 23 is spaced apart at the end of the calf fixing sleeve 22 away from the thigh fixing sleeve 21.
[0055] The placement plate 23 and the fixing plate 24 are hinged together to form a full-foot structure, with the hinge point between the toes and the sole of the foot. This full-foot structure achieves an ergonomic effect.
[0056] The fixing plate 24 has a fixing strap 241 on its front for fixing the foot, and the placement plate 23 has a surrounding plate on its front for foot restraint. The surrounding plate can surround the three sides of the placement plate 23 away from the fixing plate 24 to form a restraining structure. The fixing strap 241 can fix the toes, thereby achieving a straightening effect, while the surrounding plate can further restrict the movement direction of the foot.
[0057] The thigh fixation sleeve 21 is a soft, open sleeve structure that can wrap around the thigh. A fixing ring 211 is provided on the outer side of the thigh fixation sleeve 21. The thigh position is fixed to ensure the fixation effect, and also to relatively loosen the lower leg position, so as to ensure that the lower leg and thigh form a relative curvature, which is more in line with the lower leg elevation effect in actual operation.
[0058] In this embodiment, a soft-covering material lining can also be provided inside the thigh fixation sleeve 21 to improve patient comfort, and a silicone anti-slip pad is provided on the lining where it contacts the thigh fixation sleeve 21.
[0059] The driving device 3 is mounted on the supporting device 1 and includes a rocking drive assembly 32 for rocking the placement plate 23 and a bending drive assembly 31 for rotating the fixed plate 24. The bending drive assembly 31 includes a telescopic motor 311 fixedly mounted on the back of the placement plate 23. The output end of the telescopic motor 311 is provided with a flexible shaft guide rod 313. The end of the flexible shaft guide rod 313 away from the telescopic motor 311 is fixedly connected to the fixed plate 24 through a fixing block 314. The flexible shaft guide rod 313 is also provided with a guide ring 312 for guiding the flexible shaft guide rod 313. The guide ring 312 is fixedly mounted on the placement plate 23 and located near the hinge point between the fixed plate 24 and the placement plate 23. The telescopic motor 311 enables the flexible shaft guide rod 313 to extend and retract. One end of the flexible shaft guide rod 313 is fixed to the fixed plate 24. When the flexible shaft guide rod is squeezed by the telescopic motor 311, it expands, forcing the fixed plate 24 to bend to the other side. To improve the guiding bending effect, a guide ring 312 is provided on the placement plate 23, which can further improve the guiding effect and prevent excessive bending and damage from bending to the left or right.
[0060] The swing assembly includes a first motor 321 fixedly mounted on the carrier device 1. A steering frame 322 for horizontal steering is provided on the output end of the first motor 321. A steering ring 323 for vertical steering is rotatably provided on the inner side of the steering frame 322. The outer wall of the steering ring 323 away from the steering frame 322 is fixedly connected to the end of the placement plate 23 away from the fixed plate 24 by a connecting post 324. The swing assembly also includes a second motor 327 disposed next to the first motor 321. A first steering link 326 for controlling the direction of rotation is provided on the output end of the second motor 327. A second steering link 325 for transmitting force is provided on the end of the first steering link 326 away from the second motor 327. The second steering link 325, which is sleeved on the connecting post 324 away from the first steering link 326, controls the amount of rotation of the placement plate 23. The horizontal steering of the steering frame 322 can create a slight left-right rotation effect on the sole of the foot. The steering ring 323, which is rotatably set inside the steering frame 322, can cooperate with the steering frame 322 to form a vertical rotation. As is well known, the rotatability in two directions can create a spherical disturbance effect, thereby forming a 360° toe rotation at the sole of the foot. In order to control the rotation force and the traction and guiding effect after rotation, the position of the connecting column 324 can be limited by the control of the second motor 327, the first steering linkage 326 and the second steering linkage 325. Only a slight movement is needed to form a 360° rotation at the toe of the foot. The second motor 327 provides the control force to achieve the ankle joint rotation movement effect. Furthermore, by adjusting the rotation speed of the motor, the holding time can be adjusted and the holding force can be gradually increased.
[0061] The first motor 321 is a disc-shaped servo motor, and the steering frame 322 has a U-shaped structure. The outer radial side of the steering ring 323 is connected to the two end shafts of the steering frame 322. The disc-shaped servo motor can reduce the height and make it more physiologically appropriate for patients to use, while the U-shaped steering frame 322 makes it easier to install and fix.
[0062] The first steering link 326 and the second steering link 325 are right-angled structures. The right-angled structure ensures that the steering adjustment will not interfere with the rotation of the steering frame 322 and the steering ring 323. The second steering link 325 is mainly designed to extend the first steering link 326, thereby extending the control range.
[0063] The second motor 327 is fixedly mounted beside the first motor 321 via a mounting plate 13 fixedly mounted on the carrier device 1. The axis of the output end of the second motor 327 is collinear with the hinge axis of the steering ring 323 and the steering frame 322; the hinge axis of the hinge end of the first steering link 326 and the second steering link 325 is collinear with the axis of the steering ring 323. The collinearity of the axis of the second motor 327 allows for better correction of the motor's rotation direction.
[0064] Working effect: The telescopic motor 311 enables the flexible shaft guide rod 313 to extend and retract. One end of the flexible shaft guide rod 313 is fixed to the fixed plate 24. When the flexible shaft guide rod is squeezed by the telescopic motor 311, it expands, forcing the fixed plate 24 to bend to the other side. In order to improve the guiding bending effect, a guide ring 312 is provided on the placement plate 23, which can further improve the guiding effect and prevent excessive bending and damage from bending to the left or right.
[0065] The horizontal steering of the steering frame 322 can create a slight left-right rotation effect on the sole of the foot. The steering ring 323, which is rotatably set inside the steering frame 322, can cooperate with the steering frame 322 to form a vertical rotation. As is well known, the rotatability in two directions can create a spherical disturbance effect, thereby forming a 360° toe rotation at the sole of the foot. In order to control the rotation force and the traction and guiding effect after rotation, the position of the connecting column 324 can be limited by the control of the second motor 327, the first steering linkage 326 and the second steering linkage 325. Only a slight movement is needed to form a 360° rotation at the toe of the foot. The second motor 327 provides the control force to achieve the ankle joint rotation movement effect. Furthermore, by adjusting the rotation speed of the motor, the holding time can be adjusted and the holding force can be gradually increased.
[0066] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
