Description

Technical Field

[0001] The present invention relates to the technical field of ankle and foot rehabilitation, and in particular to an ankle and foot orthotic exercise rehabilitation device. Background Art

[0002] The ankle and foot are important movement and support structures of the human body, consisting of the ankle joint and the foot. Its functions include walking, running, jumping, and maintaining body balance. The stability of the ankle joint is crucial for the normal function of the foot, and the complex structure of the foot provides support and cushioning capabilities for the human body. However, the ankle and foot are susceptible to injuries, such as ankle sprains, fractures, tendon injuries, etc. These injuries may lead to problems such as ankle instability, foot drop, and muscle atrophy, seriously affecting the patient's walking ability and quality of life. After an ankle and foot injury, an ankle-foot orthosis is a commonly used assistive device that provides external support, limits abnormal movement of the ankle joint, relieves pain, promotes healing, and helps patients restore normal gait. However, current ankle-foot orthoses mainly focus on providing physical support and protection, but lack the function of rehabilitation training for the ankle and foot. After searching, the Chinese patent with the announcement number CN220213174U discloses an ankle-foot orthosis exercise rehabilitation device, which includes a base, a main housing, two calf support plates and two ankle-foot support plates. The main housing is fixedly installed on the upper middle part of the base, and the two calf support plates are arranged on both sides of the main housing. The calf support plates are adjustable and installed on the base. The driver of the main housing is connected to the output shaft, and the two ankle-foot support plates are connected to the corresponding output shafts respectively. A telescopic swing arm is connected between the ankle-foot support plate and the output shaft, and the telescopic swing arm is used to adjust The distance between the ankle-foot support plate and the output shaft is such that the patient's ankle joint is coaxial with the rotation center of the output shaft. The ankle-foot support plate is also connected to a foot strap. The above technical solution mainly uses a driver to drive the output shaft to rotate, and drives the ankle-foot support plate to rotate through the output shaft and the telescopic swing arm. The ankle-foot support plate rotates around the rotation center of the output shaft, thereby realizing plantar flexion, dorsiflexion, plantar flexion stop and dorsiflexion stop functions, thereby achieving the purpose of ankle and foot rehabilitation training. However, the above technical solution still has shortcomings in actual use: The device mainly uses a driver to drive the ankle-foot support plate to rotate and achieve plantar flexion and dorsiflexion movements. However, functional recovery of the ankle and foot requires not only joint mobility training, but also muscle strength training. The device can only provide single joint mobility training and cannot meet the patient's needs for comprehensive rehabilitation. The rehabilitation training function is single and the rehabilitation effect is poor.

[0003] In order to solve the above problems, this application proposes an ankle-foot orthosis exercise rehabilitation device. Summary of the Invention

[0004] The present invention proposes an ankle-foot orthosis exercise rehabilitation device, which solves the problem that the training device in the related art can only provide single joint movement training, cannot meet the patient's needs for comprehensive rehabilitation, has a single rehabilitation training function, and has poor rehabilitation effect.

[0005] The present invention provides an ankle-foot orthosis rehabilitation device, comprising a box, an elastic member, a piston module, a pedal training member, and two foot-punching members; A fixing seat is installed in the box body, and a downward-inclined slide is provided in the fixing seat.

[0007] As a further optimization scheme of the present invention, the piston module includes a loading tube and a piston member. The loading tube is installed on the side of the fixed seat and is located at the downward inclined end of the slide. The piston member is slidably arranged in the loading tube and connected to the pedal training member. The foot-punching member is connected to the loading tube.

[0008] As a further optimization solution of the present invention, the piston member includes a piston body, the piston body is slidably arranged in the loading tube, and a connecting rod connected to the pedal training member is installed on the piston body.

[0009] As a further optimization scheme of the present invention, the foot-washing piece includes a liquid flow tube and a conduit. The end of the loading tube away from the fixed seat is connected to two conduits, and the ends of the two conduits away from the loading tube are both connected to liquid flow tubes. The two liquid flow tubes are symmetrically arranged along the fixed seat, and both of the liquid flow tubes are provided with a plurality of spaced liquid flow holes, and the liquid flow holes are facing the area where the pedal training piece is located.

[0010] As a further optimization scheme of the present invention, the limiting member includes an electric push rod, which is installed on the side of the fixed seat and located at the downward inclined end of the slide, and the electric push rod is located above the piston module. The driving end of the electric push rod is connected to a limiting block located in the slide, and the limiting block is used to limit the sliding position of the pedal training piece in the slide. A pressure sensor is installed on the limiting block, an indicator light is installed on the box body, and the pressure sensor is connected to the indicator light.

[0011] As a further optimization scheme of the present invention, the pedal training piece includes a hollow block, which is slidably arranged in the middle of the slide, and the hollow block is connected between the first insertion rod and the connecting rod. A dual-axis motor is installed in the hollow block, and the two output ends of the dual-axis motor are connected to the center block. The two center blocks are connected to connecting arms, and the pedal body is rotatably installed on the end of the connecting arm away from the center block. The pedal body is connected to an elastic strap, and two liquid flow tubes are respectively located under the two pedal bodies.

[0012] As a further optimization solution of the present invention, a controller is installed on the side of the box, and the indicator light, dual-axis motor, electric push rod, and pressure sensor are all connected to the controller.

[0013] As a further optimization solution of the present invention, a lifting handle is installed on the fixing seat; The lifting handle member includes a vertical tube, which is installed on the top of the fixing seat. A lifting rod is inserted into the vertical tube. A bolt that is threadedly connected to the vertical tube and pressed against the lifting rod is provided. Two handle bars are symmetrically connected to the lifting rod.

[0014] As a further optimization solution of the present invention, a seat plate is installed on the box body, and a drain pipe is connected to the bottom of the box body.

[0015] The above technical solution of the present invention has the following beneficial technical effects: 1. When using the present invention, a blood-activating and blood-stasis-removing medicinal liquid is first injected into the box. Then the patient can sit on the box and step on the pedal training piece with both feet. The pedal training piece drives the feet to perform pedaling motion, similar to riding a bicycle, thereby achieving rehabilitation training for the ankle and foot positions. After training for a period of time, in order to perform strength training on the feet, the patient can use the force of the foot to push the pedal training piece to slide in the slideway and stretch the elastic piece. When the foot retracts the force, the elastic action of the elastic piece can return the pedal training piece to its original position. Through the elastic action of the elastic piece, strength training for the ankle and foot positions of the feet is achieved, overcoming the deficiency of the existing technology that can only provide single joint movement training, meeting the comprehensive rehabilitation needs of the patient and effectively improving the rehabilitation effect. 2. The present invention uses the force of the foot to push the pedal training piece to slide in the slideway, which can make the components in the piston module move accordingly, so that the medicine in the piston module is pushed into the foot-washing piece, and then discharged through the foot-washing piece, and the medicine flows to the position of the pedal training piece, accelerating the flow of the medicine at the ankle and foot position, and also preventing the precipitation of the medicine. When the pedal training piece returns to its original position, the components in the piston module follow and return to their original position, and the medicine can return to the piston module along the foot-washing piece. Such a cycle allows the ankle and foot to better contact and absorb the medicine, fully exerting the effect of the blood-activating and blood-stasis-removing medicine, further promoting the rehabilitation of the ankle and foot, and also preventing the precipitation of the medicine, ensuring the therapeutic effect. The above design not only provides a mechanical rehabilitation training function, but also realizes the combination of drug therapy and physical therapy through drug impact. This multi-dimensional rehabilitation method can simultaneously act on the muscles, joints and soft tissues of the ankle and foot, promote rehabilitation from multiple aspects, and make the rehabilitation training effect better; 3. Because different patients require different training intensities, the present invention uses a limiter to limit the distance the pedal training piece can slide within the slideway. The elastic member connected to the pedal training piece can only be stretched to a certain extent. This allows for providing foot strength training of appropriate intensity to each patient based on their physical condition and rehabilitation stage, implementing personalized rehabilitation training programs, improving the relevance and effectiveness of rehabilitation training, and helping patients better restore ankle and foot function. 4. In order to facilitate patients and medical staff to observe the training results more conveniently, when the patient's foot exerts force to push the pedal training piece to slide in the slide, the present invention is provided with a pressure sensor on the limit piece. Only when the pedal training piece hits the pressure sensor each time, the indicator light on the box will flash. This design allows patients and medical staff to intuitively understand whether the patient's foot strength training meets the requirements each time, timely grasp the training situation, facilitate monitoring and adjustment of the training process, ensure the quality and effect of rehabilitation training, and also enhance the patient's confidence and enthusiasm for rehabilitation training.

[0018] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0019] like Figure 1-10 As shown, the ankle-foot orthosis rehabilitation device proposed by the present invention includes a box body 1, an elastic member 3, a piston module 4, a pedal training member 5 and two foot-punching members 7; A fixing base 2 is installed in the box body 1, and a downward-inclined slide 21 is provided in the fixing base 2. An elastic member 3 is installed in the slide 21. A piston module 4 is installed on the side of the fixing base 2 and is located at the downward-inclined end of the slide 21. A pedal training piece 5 is slidably matched with the slide 21, and the pedal training piece 5 is respectively connected to the elastic member 3 and the piston module 4. Two foot-flushing pieces 7 are arranged in the box body 1 and are respectively located on both sides of the fixing base 2. Both foot-flushing pieces 7 are connected to the piston module 4 and are used to discharge liquid to the area of ​​the pedal training piece 5. A limiting piece 6 for limiting the position of the pedal training piece 5 is installed on the fixing base 2. When pressure is applied to the pedal training piece 5 and it slides along the slideway 21 , the elastic piece 3 is stretched, pushing the liquid in the piston module 4 into the foot flushing piece 7 and discharged through the foot flushing piece 7 to the area where the pedal training piece 5 is located.

[0020] The patient can sit on the box 1, step on both sides of the pedal training piece 5 with both feet, and then inject a blood-activating and blood-stasis-removing liquid into the box 1 until the patient's feet are submerged in the liquid. When pressure is applied to the pedal training piece 5, the pedal training piece 5 will slide along the downward inclined end of the slide 21. During this process, the elastic piece 3 connected to the pedal training piece 5 is stretched, which can provide resistance for foot strength training. At the same time, the pedal training piece 5 pushes the components in the piston module 4 to move, so that the liquid in the piston module 4 is squeezed, and the liquid enters the foot-washing piece 7 through the connecting structure and is discharged toward the opening of the pedal training piece 5 through the foot-washing piece 7, forming a liquid impact flow. Acting on the ankle and foot area, when the foot retracts its force, the elastic part 3 drives the pedal training part 5 to slide in the opposite direction along the slide 21 and reset, and the parts in the piston module 4 are reset accordingly. The medicine liquid flows back to the piston module 4 through the foot-washing part 7 under the action of negative pressure, completing a cycle. During this process, the limiter 6 can limit the sliding position of the pedal training part 5 to control the training intensity. This design realizes the stretching and resetting of the elastic part 3 through the sliding of the pedal training part 5. Combined with the liquid flow of the piston module 4 and the foot-washing part 7, it not only provides mechanical resistance for strength training, but also assists rehabilitation through the impact of the medicine liquid, enriching the form and effect of rehabilitation training.

[0021] like Figure 2 、 Figure 4 and Figure 5 As shown, in this embodiment, the elastic member 3 includes a fixed tube 31, a spring 32 and a first insertion rod 33. The fixed tube 31 is installed in the slide 21, and the spring 32 is installed in the fixed tube 31. The first insertion rod 33 slides through the end of the fixed tube 31 close to the pedal training piece 5 and is connected to the spring 32, and the end of the first insertion rod 33 away from the fixed tube 31 is connected to the pedal training piece 5.

[0022] When the pedal training piece 5 slides, the first insertion rod 33 is subjected to tension and slides outward along the fixed tube 31 close to the end of the pedal training piece 5, stretching the spring 32 in the fixed tube 31, and generating resistance to the sliding of the pedal training piece 5, thereby increasing the load of the foot strength training. When the foot unloads the force, the spring 32 returns to its original position, pushing the first insertion rod 33 to reset, driving the pedal training piece 5 back to its initial position. The above design can adapt to the strength training needs of different patients. At the same time, its reset process can assist patients in completing training movements and improve the continuity and comfort of training.

[0023] like Figure 3 and Figure 6 As shown, in this embodiment, the piston module 4 includes a loading tube 41 and a piston member 42. The loading tube 41 is installed on the side of the fixed seat 2 and is located at the downward inclined end of the slide 21. The piston member 42 is slidably set in the loading tube 41 and is connected to the pedal training member 5. The foot-punching member 7 is connected to the loading tube 41.

[0024] When the pedal training piece 5 slides, the piston piece 42 connected to it slides in the loading tube 41. The sliding of the piston piece 42 squeezes the liquid in the loading tube 41, and the liquid is discharged through the foot-washing piece 7 connected to the loading tube 41, forming a directional flow of medicine. When the pedal training piece 5 is reset, the piston piece 42 slides in the opposite direction, and a negative pressure is formed in the loading tube 41. The medicine is sucked into the loading tube 41 through the foot-washing piece 7, realizing the circulation of the medicine. The reciprocating sliding of the piston piece 42 acts like a pump body, forcing the medicine to circulate between the piston module 4 and the foot-washing piece 7, ensuring that the medicine can continuously and stably impact the ankle and foot area, enhancing the drug penetration effect, and at the same time, through the resistance of liquid flow, further increasing the load when the pedal training piece 5 slides, strengthening the strength training effect.

[0025] like Figure 6 As shown, in this embodiment, the piston member 42 includes a piston body 421, which is slidably arranged in the loading tube 41, and a connecting rod 422 connected to the pedal training piece 5 is installed on the piston body 421; when the pedal training piece 5 slides along the slide 21, the piston body 421 is driven to make a linear motion in the loading tube 41 through the connecting rod 422. When the piston body 421 slides forward, the liquid in the loading tube 41 is pressed into the foot-washing piece 7 and sprayed out through the foot-washing piece 7. When the piston body 421 slides backward, a negative pressure is generated in the loading tube 41, and the liquid flows back to the loading tube 41 along the foot-washing piece 7. The connecting rod 422 converts the mechanical motion of the pedal training piece 5 into the reciprocating motion of the piston body 421, realizing the conversion of mechanical energy into hydraulic energy. This structural design is simple and reliable, can accurately transmit motion, and ensure the stability and effectiveness of the medicine circulation. At the same time, the sealing cooperation between the piston body 421 and the loading tube 41 ensures that the liquid will not leak, maintaining the normal operation of the hydraulic system.

[0026] like Figure 2 and Figure 3 As shown, in this embodiment, the foot-washing member 7 includes a liquid flow tube 71 and a conduit 72. The end of the loading tube 41 away from the fixed seat 2 is connected to the two conduits 72. The ends of the two conduits 72 away from the loading tube 41 are both connected to the liquid flow tube 71. The two liquid flow tubes 71 are symmetrically arranged along the fixed seat 2. A plurality of spaced liquid flow holes 73 are provided on the two liquid flow tubes 71, and the liquid flow holes 73 are oriented toward the area where the pedal training member 5 is located.

[0027] When the liquid flows into the liquid flow tube 71, it is ejected from the liquid flow hole 73 to form multiple fine streams of liquid medicine, which evenly impact the pedal training piece 5 and the ankle and foot parts located above the liquid flow tube 71. The symmetrically arranged liquid flow tubes 71 can simultaneously impact the ankle and foot parts of both feet with liquid medicine to ensure the consistency of the rehabilitation effect on both sides. The spacing and orientation design of the liquid flow holes 73 enable the liquid medicine to act comprehensively and accurately on the key parts of the ankle and foot, such as the area around the ankle joint and the sole muscles, thereby enhancing the contact area and action intensity between the drug and the tissue. At the same time, the mechanical stimulation generated by the impact of the liquid medicine can help relax muscles, promote blood circulation, and cooperate with mechanical training to enhance the overall rehabilitation effect.

[0028] like Figure 3 、 Figure 4 and Figure 7 As shown, in this embodiment, the limiter 6 includes an electric push rod 61, which is installed on the side of the fixed seat 2 and located at the downward inclined end of the slide 21, and the electric push rod 61 is located above the piston module 4. The driving end of the electric push rod 61 is connected to a limit block 62 located in the slide 21, and the limit block 62 is used to limit the sliding position of the pedal training piece 5 in the slide 21. A pressure sensor 63 is installed on the limit block 62, an indicator light 101 is installed on the box body 1, and the pressure sensor 63 is connected to the indicator light 101.

[0029] During use, the telescopic length of the electric push rod 61 can be pre-set, and the position of the limit block 62 within the slide 21 can be adjusted to limit the maximum sliding distance of the pedal training piece 5. When the pedal training piece 5 slides into contact with the limit block 62, the pressure sensor 63 detects a pressure signal and transmits the signal to the controller 102. The controller 102 controls the indicator light 101 to flash, prompting the patient or medical staff that the set training intensity has been reached. This structure achieves personalized adjustment of the training intensity through the precise control of the electric push rod 61 to meet the needs of patients at different stages of rehabilitation. The combination of the pressure sensor 63 and the indicator light 101 provides intuitive feedback for the training process, making it easier for patients to grasp the training rhythm, ensuring that each training session reaches an effective intensity, avoiding insufficient or excessive training, and improving the scientific nature and safety of rehabilitation training.

[0030] like Figure 2 、 Figure 8 and Figure 9As shown, in this embodiment, the pedal training piece 5 includes a hollow block 51, which is slidably arranged in the middle of the slide 21, and the hollow block 51 is connected between the first insertion rod 33 and the connecting rod 422. A dual-axis motor 52 is installed in the hollow block 51, and the two output ends of the dual-axis motor 52 are connected to the center block 53. The two center blocks 53 are connected to connecting arms 54. The pedal body 55 is rotatably installed at one end of the connecting arm 54 away from the center block 53. The pedal body 55 is connected to an elastic strap 56, and the two liquid flow tubes 71 are respectively located under the two pedal bodies 55.

[0031] When the dual-axis motor 52 drives the central block 53 to rotate, the central block 53 drives the pedal body 55 to rotate around the end of the connecting arm 54 through the connecting arm 54, simulating the action of riding a bicycle to achieve ankle and foot joint mobility training. The elastic strap 56 fixes the patient's foot on the pedal body 55 to ensure the stability and accuracy of the movement. The two liquid flow tubes 71 are located below the pedal body 55. During the joint activity training process, the medicine is sprayed out from the liquid flow hole 73, and the ankle and foot parts in motion are continuously impacted with the medicine to promote blood circulation and drug absorption. The dual-axis motor 52 provides active movement power and can adjust the speed and rotation angle according to the patient's rehabilitation condition to achieve switching between passive, active or resistance training, enriching the training mode. The rotational movement of the pedal body 55 is combined with the sliding movement of the slide 21, so that the ankle and foot can perform joint activity training such as flexion and extension, as well as strength training, realizing multi-dimensional rehabilitation.

[0032] like Figure 1 As shown, in this embodiment, a controller 102 is installed on the side of the box 1, and the indicator light 101, the dual-axis motor 52, the electric push rod 61, and the pressure sensor 63 are all connected to the controller 102; when the patient is training, the pressure sensor 63 transmits the detected pressure signal to the controller 102, and the controller 102 determines whether to trigger the indicator light 101 to flash according to the preset program. Medical staff can set the operating parameters of the dual-axis motor 52 through the controller 102, such as speed, rotation direction, training time, etc., to control the training rhythm of the ankle and foot joint activities. At the same time, the controller 102 adjusts the extension and contraction amount of the electric push rod 61, changes the position of the limit block 62, and sets the sliding distance of the pedal training piece 5, thereby adjusting the strength training intensity. The controller 102 realizes intelligent control and coordinated work of various components of the device, so that the rehabilitation training process can be accurately adjusted and monitored in real time, thereby improving the degree of automation and personalization of rehabilitation training, and ensuring the scientific nature and effectiveness of the training plan.

[0033] like Figure 1 and Figure 10As shown, in this embodiment, a lifting handle member 8 is installed on the fixing base 2; the lifting handle member 8 includes a vertical tube 81, which is installed on the top of the fixing base 2, and a lifting rod 82 is inserted into the vertical tube 81. A bolt 83 that is threadedly connected to the vertical tube 81 and is pressed against the lifting rod 82, and two handle bars 84 are symmetrically connected to the lifting rod 82; the patient or medical staff adjusts the height of the lifting rod 82 in the vertical tube 81 up and down according to the height or training posture requirements, and tightens the bolt 83 to fix it after appropriate adjustment. The two symmetrical handle bars 84 on the lifting rod 82 provide grip support for the patient.

[0034] like Figure 1 As shown, in this embodiment, a seat plate 103 is installed on the box body 1 to provide a support surface for the patient's sitting training. The patient sits on the seat plate 103 and places both feet on the pedal training piece 5 to facilitate ankle and foot rehabilitation training. A drain pipe 104 is connected to the bottom of the box body 1. A valve is installed on the drain pipe 104 for discharging the liquid medicine in the box body 1. When the liquid medicine needs to be replaced or the box body 1 needs to be cleaned, the valve of the drain pipe 104 is opened and the liquid medicine can be discharged from the box body 1, which is convenient and quick.

[0035] The specific working principle of the present invention is as follows: First, a blood-activating and blood-stasis-removing medicine liquid is injected into the box body 1. The patient sits on the seat plate 103, with both feet fixed to the pedal body 55 by elastic straps 56, and holds the handlebar 84 with both hands to maintain balance. According to rehabilitation needs, the operating parameters of the dual-axis motor 52 are set through the controller 102 to drive the pedal body 55 to rotate and perform ankle and foot joint mobility training. When strength training is needed, the patient exerts force with his feet to push the hollow block 51 to slide downward along the slide 21, stretching the first insertion rod 33 and the spring 32, and at the same time driving the piston body 421 to slide in the loading tube 41 through the connecting rod 422, pressing the medicine liquid in the loading tube 41 into the liquid flow tube 71 through the catheter 72 and spraying it toward the foot position. When the hollow block 51 slides to contact the limit block 62, the pressure sensor 63 triggers the indicator light 10 1 flashes, indicating that the training intensity has been reached. After the foot is retracted, the spring 32 resets and drives the hollow block 51 to return, the piston body 421 resets synchronously, and the medicine flows back to the loading tube 41, completing a strength training cycle. During the training, the position of the limit block 62 can be adjusted by the electric push rod 61 to change the sliding distance of the hollow block 51 and adjust the strength training intensity. The height of the handle 84 can be adjusted by the lifting rod 82 to adapt to the body shape requirements of different patients. After the training, the medicine in the box 1 is discharged through the drain pipe 104 for cleaning or replacement. The entire device combines mechanical training with medicine impact to achieve multi-dimensional rehabilitation of joint range of motion training, strength training and drug treatment. At the same time, through intelligent control and personalized adjustment, the effect and safety of rehabilitation training are improved.
