Description

Technical Field

[0001] The present invention relates to the technical field of rapid leg rehabilitation training, in particular to a rapid leg rehabilitation training system. Background Art

[0002] In modern medicine, leg rehabilitation training plays a vital role for patients who have been injured, have undergone surgery, or have other motor function limitations. The legs are important motor organs in the human body and are responsible for multiple functions such as walking, standing, and exercising. Whether it is due to trauma such as fractures, joint injuries, muscle strains, or leg dysfunction caused by long-term bed rest, nerve damage, etc., scientific and effective rehabilitation training is needed to restore its normal function. However, traditional leg rehabilitation training methods have many limitations.

[0003] The existing Chinese patent with publication number CN117815036A includes a support mechanism; a linear drive mechanism is installed on the upper part of the support mechanism; a seat is vertically installed on the linear drive mechanism; a leg circular rotation mechanism is installed on one side of the seat; a leg up and down swing mechanism is connected to the leg up and down swing mechanism; and a leg forward and backward movement mechanism is connected to the leg up and down swing mechanism.

[0004] When the above device is in use, the leg circular rotation mechanism is used to drive the patient's legs to rotate in a compass-like manner, and the leg up and down swing mechanism can be used to drive the patient's legs to move up and down through the leg circular rotation mechanism. At the same time, after the leg circular rotation mechanism and the leg up and down swing mechanism have stopped moving, the leg forward and backward movement mechanism can be used to drive the patient's legs to move forward and backward, thereby achieving the movement of the patient's hip joints, knee joints and ankle joints. However, in actual use, simulated cycling movements are an effective rehabilitation training method that can promote the recovery of knee and hip joint mobility, enhance leg muscle strength, and improve blood circulation. The movement trajectory and rhythm of traditional training equipment are inconsistent with the natural cycling movements of the human body, causing patients to feel uncomfortable during training, and even easily cause secondary damage to joints and muscles, affecting the rehabilitation effect. Therefore, it is difficult to assist patients in lower limb simulated cycling movements for rehabilitation training.

[0005] To this end, we proposed a rapid leg rehabilitation training system. Summary of the Invention

[0010] Preferably, the arc-shaped splint is provided with a massage mechanism for pressing the patient's calf muscles, and the massage mechanism includes an air bag fixedly connected to the inner wall of the arc-shaped splint on each side for pressing the patient's calf muscles, and a ventilation tube is passed through and fixedly connected to the two air bags on each side, and one end of the track rod on each side is fixedly connected to a cylindrical shell, and the ventilation tube on each side is passed through the inner wall of the cylindrical shell on the adjacent side away from the end of the air bag and is fixedly connected.

[0011] Preferably, one end of the track rod on each side close to the cylindrical shell is penetrated and connected to a moving rod for horizontal movement, and the end of the moving rod away from the cylindrical shell is fixedly connected to the moving block, and the end of each moving rod away from the moving block is penetrated to the inner wall of the cylindrical shell and fixedly connected to a piston plate for inflating or deflating the interior of the airbag.

[0012] Preferably, the moving block is provided with an auxiliary mechanism for assisting the patient's ankle in rehabilitation training, and the auxiliary mechanism includes two racks fixedly connected at symmetrical positions on one side of the two moving blocks to drive the foot rest to rotate back and forth, and one end of the foot rest on each side close to the rack is coaxially fixed with a third gear that meshes with the teeth on the rack for transmission.

[0013] Preferably, the footrest is provided with a sensing mechanism for stimulating the soles of the patient's feet, and the sensing mechanism includes a support groove and a support groove both provided on the two footrests, a cylindrical rod passing through the inner walls of the support groove and the movable groove and connected thereto for lifting and moving, the ends of the two cylindrical rods are fixedly connected to a rectangular plate, and the rectangular plate is movably supported on the inner wall of the support groove, and each of the rectangular plates is fixedly connected to a plurality of evenly placed extrusion blocks.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Through the meshing transmission of the first gear and the second gear, the crank can be driven to rotate on a fixed axis, thereby assisting the patient's legs in simulating cycling movements, ensuring the stability and continuity of the movement, and avoiding jamming or unnatural movement of the patient's legs due to poor power transmission. This mode of movement is more in line with the physiological movement laws of the human body. Compared with traditional rehabilitation training equipment, it can effectively avoid secondary damage to the patient's legs due to unnatural movement patterns, reduce discomfort in the joints and muscles, and simulated cycling exercises can fully activate the knee and hip joints, enhance leg muscle strength, improve blood circulation, and accelerate the recovery process.

[0017] 2. Utilizing the inflation and exhaust functions of the airbag to dynamically press the patient's calf muscles can effectively massage and relax the calf muscles while the patient is exercising their legs, relieve muscle tension and fatigue, promote blood circulation, and accelerate the recovery of leg muscles. Through the linkage design of the piston plate and the moving rod, the massage mechanism can be synchronized with the leg movement, further improving the effect of rehabilitation training. In addition, the airbag massage has the characteristics of soft and uniform pressing, which can provide patients with a comfortable massage experience, reduce the interruption of rehabilitation training caused by pressing discomfort, and improve patient compliance.

[0018] 3. Through the meshing transmission of the rack and the third gear, the footrest is driven to rotate back and forth, thereby assisting the patient's ankle in rehabilitation training. In the process of simulating riding movements, the patient's ankle can be driven to rotate back and forth synchronously, so that the ankle joint can be fully active, the flexibility and stability of the ankle are enhanced, and ankle stiffness and functional degradation caused by long-term lack of exercise are prevented. At the same time, the movement of the auxiliary mechanism is closely integrated with the leg movement, which can ensure the consistency and coordination of the patient's movements during rehabilitation training, which is closer to the natural riding movement state and helps promote the overall functional recovery of the patient's legs and ankles.

[0019] 4. Through the coordination of the cylindrical rod, rectangular plate, extrusion block and the first and second protrusions, the soles of the patient's feet are rhythmically squeezed and stimulated, which can enhance the patient's perception of the sole muscles, promote blood circulation in the soles, and relieve sole fatigue during the patient's simulated cycling movements. At the same time, it stimulates the nerve endings in the soles, activates the proprioception of the feet, and improves the patient's perception of the foot position and movement state, which helps to improve the patient's sense of balance and gait stability, and promotes the overall functional recovery of the feet and legs.

[0020] The coordinated use of the above-mentioned structure solves the problem that in actual use of existing devices, simulated cycling movements are an effective rehabilitation training method, which can promote the recovery of knee and hip joint mobility, enhance leg muscle strength, and improve blood circulation. The movement trajectory and rhythm of traditional training equipment are inconsistent with the natural cycling movements of the human body, causing patients to feel uncomfortable during training and even easily causing secondary damage to joints and muscles, affecting the rehabilitation effect. Therefore, it is difficult to assist patients in lower limb simulated cycling movements for rehabilitation training. BRIEF DESCRIPTION OF THE DRAWINGS

[0050] The footrest 6 is provided with a sensing mechanism for stimulating the sole of the patient's foot. The sensing mechanism includes two support grooves 601 and support grooves 601, which are both opened on the two footrests 6. A cylindrical rod 21 passes through the inner walls of the support grooves 601 and the movable grooves 602 and is connected to the cylindrical rod 21 for lifting and movement. The ends of the two cylindrical rods 21 are fixedly connected to rectangular plates 22, and the rectangular plates 22 are movably supported on the inner walls of the support grooves 601. Each of the rectangular plates 22 is fixedly connected to a plurality of evenly placed extrusion blocks 23.

[0051] The bottom ends of the lifting rods 5 on both sides are fixedly connected to an arc-shaped shell 26, and the inner wall of each arc-shaped shell 26 is fixedly connected to a plurality of second protrusions 27 that push the rectangular plate 22 to move up and down and back and forth. The bottom ends of the two columnar rods 21 are fixedly connected to a first protrusion 24 that cooperates with the second protrusion 27, and each of the first protrusions 24 is fixedly connected to the opposite surface of the movable groove 602 with a second spring 25 that guides the rectangular plate 22 to reset and move.

[0053] By means of the arc-shaped shell 26 provided on the lifting rod 5, the arc-shaped shell 26 is fixedly supported on the lifting rod 5, so that the arc-shaped shell 26 can be sleeved on the outer contour of the bottom of the footrest 6. As the footrest 6 performs a fixed-axis reciprocating swing on the lifting rod 5, the footrest 6 can drive the first protrusion 24 to synchronously reciprocate along the arc surface of the arc-shaped shell 26.

At the same time, the nerve endings of the plantar are stimulated, the proprioception of the foot is activated, and the patient's perception of the foot position and movement state is improved, which helps to improve the patient's sense of balance and gait stability, and promote the overall functional recovery of the foot and leg.

[0054] As the first protrusion 24 drives the rectangular plate 22 to move in the upward direction, the second spring 25 is in a contracted state under the action of the first protrusion 24. When the first protrusion 24 moves and disengages from the second protrusion 27, the first protrusion 24 can drive the rectangular plate 22 to reset in the downward direction under the elastic force of the second spring 25.
