Abstract
Description
Technical Field
[0001] This invention belongs to the field of exercise and rehabilitation technology, and in particular relates to a lumbar spine rehabilitation physiotherapy device. Background Technology
[0002] Lumbar spine rehabilitation physiotherapy equipment is an innovatively designed treatment device aimed at helping patients restore lumbar spine function. It is commonly used in physical therapy and rehabilitation processes. This equipment not only focuses on the rehabilitation of the lumbar spine itself but also recognizes the close link between lumbar spine health and lower limb function. Through planned physiotherapy programs, the equipment aims to enhance the strength, flexibility, and coordination of the patient's lumbar spine and lower limbs, and is particularly suitable for patients with limited lumbar spine and lower limb function due to injury, surgery, or neurological disorders.
[0003] In practical applications, existing lumbar spine and lower limb rehabilitation techniques have the following problems: In existing techniques for lumbar spine and lower limb rehabilitation, a common approach is to increase weight-bearing, requiring patients to perform lumbar flexion and extension, as well as leg lifting and lowering movements, to effectively exercise the muscles and joints. However, this method has limitations. When patients are unable to precisely and stably control the weight-bearing portion due to discomfort or injury, the weight-bearing device may become uncontrollable, moving or falling rapidly, causing significant damage to the lumbar spine and lower limbs. This is especially true when the weight is borne during lumbar flexion and leg lifting, and when the weight moves or falls freely during extension and lowering. In such cases, this exercise method often leads to uneven rehabilitation effects on both sides of the lumbar spine and the upper and lower sides of the legs, posing a certain degree of safety risk.
[0004] Based on this, the present invention designs a lumbar spine rehabilitation physiotherapy device to solve the above problems. Summary of the Invention

The fourth elastic components are fixedly connected to the outside of the second piston rod. The back side of the contact slide rod is tapered, and the contact slide rod is slidably disposed between the connecting racks.
[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This invention employs innovative designs including a drive mechanism, a flexion-extension support, a rotating contact frame, a rotating rod, an air storage cylinder, and a compression plate, achieving significant effects on lumbar spine rehabilitation. The drive mechanism allows the flexion-extension support to move smoothly up and down. Patients place their feet on the support and indirectly exercise the lumbar spine joints by controlling the bending and extension of their legs. During lumbar spine rehabilitation exercises, the rotating contact frame, by controlling the movement of the compression plate, compresses the gas in the air storage cylinder and discharges it through the connecting air hole. Because the exhaust speed of the air hole is limited, this increases the resistance when the rotating contact frame rotates, providing a safe weight-bearing exercise environment for lumbar spine rehabilitation. Whether the rotating contact frame rotates upward or downward, there is uniform resistance, ensuring the stability of the patient during exercise. In addition, when the patient's lumbar spine is weak or an accident occurs, the rotating contact frame, due to the air pressure limitation and the slow movement of the compression plate, ensures that the patient's lumbar spine is slowly reset, thus avoiding the injury that may be caused by rapid movement and greatly improving the safety of the exercise process.
[0017] 2. In this invention, a first piston frame, a first piston plate, a sealing plate, and a connecting air hole are employed. The increased air pressure inside the first piston frame can precisely control the movement of the first piston plate, thereby adjusting the sealing state of the connecting air hole by the sealing plate. This design effectively reduces the flow velocity of gas through the connecting air hole. By increasing the pressure required to squeeze and discharge gas from the storage cylinder, this invention can finely adjust the resistance during the rotation of the rotating contact frame. This feature allows the equipment to flexibly adjust the load according to the patient's lumbar spine rehabilitation needs, thereby achieving personalized rehabilitation training. Patients can adjust the difficulty of the exercise according to their own rehabilitation progress and intensity requirements, making the exercise process more flexible and varied. More importantly, through precise control of air pressure and resistance, this invention ensures that the patient's lumbar spine movement is always within a safe range during exercise. This design avoids potential injuries caused by excessive or unstable loads, providing patients with a safe and effective lumbar spine rehabilitation environment.
[0018] 3. In this invention, a second piston frame, a second piston plate, a second piston rod, and a control block are used. The patient can directly operate the control block with their hand, achieving intuitive control of the lumbar spine rehabilitation process and greatly improving the convenience of operation. When the control block moves to the left, the gas in the second piston frame is effectively squeezed through the linkage of the second piston rod and the second piston plate. The gas is then transferred to the first piston frame through the intermediate tube, thereby achieving precise adjustment of the air pressure. This design allows the device to provide precise air pressure support according to the patient's lumbar spine rehabilitation needs. In addition, the contact slide bar moves forward under the action of the control block through the squeezing of the connecting rack, and after passing the connecting rack, it is assisted in resetting by the fourth elastic component. This mechanism ensures that the movement range of the control block can be clearly judged, thereby ensuring the accuracy and repeatability of the operation. Through the above mechanism, this invention can accurately grasp the air pressure status in the second piston frame, making the operation and adjustment method more precise and convenient. This not only provides patients with a more detailed lumbar spine rehabilitation experience, but also ensures the safety and effectiveness of the rehabilitation process. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Please see the appendix Figure 1 -Appendix Figure 9This invention provides a lumbar spine rehabilitation physiotherapy device, comprising a support base 1 and a rotating contact frame 13. A side support 2 is fixedly connected to the upper surface of the support base 1. An adjustment mechanism 3 is fixedly connected to the left side of the side support 2. A movable plate 4 is fixedly connected to the right side of the adjustment mechanism 3. The movable plate 4 is slidably connected inside the side support 2. An extension frame 5 is fixedly connected to the right side of the movable plate 4. A mounting frame 6 is fixedly connected below the extension frame 5. A back plate 7 is installed on the inner wall of the mounting frame 6. A seat plate 8 is provided on the lower surface of the mounting frame 6. A drive mechanism 9 is provided on the lower surface of the seat plate 8. A flexion-extension bracket 10 is hinged to the end of the drive mechanism 9. The flexion-extension bracket 10 is hinged to the lower surface of the seat plate 8. The front of the seat plate 8 is fixedly connected to the back plate 8. A rotating support mechanism 11 is fixedly connected to the rotating contact frame 13. A sliding groove 12 is provided on the left side of the rotating contact frame 13. The rotating support mechanism 11 is slidably connected in the sliding groove 12. A rotating connecting mechanism 15 is provided on the lower surface of the rotating support mechanism 11. An installation rod 16 is fixedly connected to the lower surface of the rotating connecting mechanism 15. The other end of the installation rod 16 is fixedly connected to the lower surface of the seat plate 8. A movable sealing mechanism 17 is fixedly connected to the upper surface of the rotating connecting mechanism 15. An intermediate tube 18 is connected to the upper surface of the movable sealing mechanism 17. The other end of the intermediate tube 18 is connected to a movable adjustment mechanism 19 located outside the mounting frame 6. A connecting rack 20 is fixedly connected to the side of the mounting frame 6 corresponding to the position of the movable adjustment mechanism 19.
[0023] The system employs a drive mechanism 9 and a flexion-extension support 10. The use of the drive mechanism 9 enables the flexion-extension support 10 to move smoothly up and down. When the patient places their foot on the flexion-extension support 10, they can effectively control the bending and extension of their leg, thereby providing targeted exercise for the joint area.
[0024] Specifically, such as Figure 1-3 As shown, the rotating support mechanism 11 includes a rotating rod 111, a support pin 112 is hinged to the side of the rotating rod 111, the support pin 112 is hinged to the front of the seat plate 8, an intermediate rod 113 is fixedly connected to the bottom end of the rotating rod 111, a sliding block 114 is fixedly connected to the bottom end of the intermediate rod 113, and a rotating connection mechanism 15 is provided on the side of the rotating rod 111.
[0025] The sliding block 114 is slidably connected in the sliding groove 12. The front and rear sides of the inner wall of the sliding groove 12 are fixedly connected with magnetic blocks 14. The side of the sliding block 114 that is close to the magnetic block 14 has the same magnetism. The sliding block 114 is T-shaped.
[0026] The rotating rod 111 rotates around the supporting pin 112, so that the rotation center point of the rotating contact frame 13 is close to the patient's leg, allowing for smooth rotational exercises. The sliding block 114 and the sliding groove 12 allow the rotating contact frame 13 to slide back and forth along the slider. When using the flexion and extension bracket 10, the rotating contact frame 13 can be slid to the foremost position, making the position of the rotating contact frame 13 more flexible. Furthermore, the setting of the magnetic block 14 allows the rotating contact frame 13 to maintain a relatively stable state using magnetic force in both the foremost and rearmost positions.
[0027] Specifically, such as Figure 4-6 As shown, the rotary connection mechanism 15 includes an air storage cylinder 1501, a pressing plate 1502 is slidably connected inside the air storage cylinder 1501, a connecting rod 1503 is fixedly connected to the pressing plate 1502, a first pin 1504 is hinged to the end of the connecting rod 1503, a first bracket 1505 is hinged to the outside of the first pin 1504 and fixedly connected to the side of the rotating rod 111, and a first elastic component 1506 is fixedly connected to the bottom of the pressing plate 1502.
[0028] The other end of the first elastic component 1506 is fixedly connected to the inner wall of the gas storage cylinder 1501. Two second pins 1509 are hinged to the outside of the gas storage cylinder 1501. A second bracket 1510 is hinged to the outside of the second pins 1509. A fixing plate 1511 is fixedly connected to the bottom of the second bracket 1510. The fixing plate 1511 is fixedly connected to the outside of the mounting rod 16.
[0029] Two limiting rings 1508 are fixedly connected inside the gas storage cylinder 1501 to prevent the extrusion plate 1502 from moving. The two limiting rings 1508 are located on both sides of the extrusion plate 1502. Two connecting air holes 1507 are opened on the gas storage cylinder 1501. The two limiting rings 1508 are located between the two connecting air holes 1507. The movable sealing mechanism 17 is located outside the gas storage cylinder 1501.
[0030] As the rotating rod 111 drives the connecting rod 1503 to move, the extrusion plate 1502 moves upward. As the extrusion plate 1502 moves, it extrudes the gas on the upper side of the gas storage cylinder 1501 through the connecting air hole 1507. At the same time, because the size of the connecting air hole 1507 limits the flow speed of the gas, the movement of the extrusion plate 1502 is subject to resistance from the air pressure, which increases the load on the rotation of the rotating contact frame 13. Meanwhile, when the rotating contact frame 13 is slowly moved by the legs, its resistance will decrease. Specifically, such as Figure 6As shown, the movable sealing mechanism 17 includes a first piston frame 171 fixedly connected to the air storage cylinder 1501. Two first piston plates 172 are slidably connected inside the first piston frame 171. A first piston rod 173 is fixedly connected to the side of the first piston plate 172 near the connecting air hole 1507. A sealing plate 174 is fixedly connected to the end of the first piston rod 173 located outside the first piston frame 171.
[0031] The sealing plate 174 is slidably connected to the gas storage cylinder 1501. The size of the sealing plate 174 is larger than the size of the connecting air hole 1507. The first piston rod 173 is sleeved with a second elastic component 175. The two ends of the second elastic component 175 are fixedly connected to the inner walls of the first piston plate 172 and the first piston frame 171, respectively. The intermediate tube 18 is connected to the first piston frame 171 at the position between the two first piston plates 172.
[0032] The second elastic component 175 is used to ensure that when the air pressure inside the first piston frame 171 is normal, the sealing plate 174 and the connecting air hole 1507 are in a separated state. The increased air pressure inside the first piston frame 171 controls the two first piston plates 172 to move away from each other. The first piston plates 172 control the sealing plate 174 to move through the first piston rod 173. The movement of the sealing plate 174 blocks the connecting air hole 1507, thereby reducing the flow speed of the gas in the connecting air hole 1507. This can further increase the pressure required for the extrusion plate 1502 to expel the gas from the gas storage cylinder 1501. Specifically, such as Figure 7-9 As shown, the movable adjustment mechanism 19 includes a second piston frame 191 fixedly connected to the outside of the mounting frame 6, a second piston plate 192 slidably connected inside the second piston frame 191, a second piston rod 193 fixedly connected to the side of the second piston plate 192, a control block 195 fixedly connected to one end of the second piston rod 193 outside the second piston frame 191, the control block 195 slidably connected to the outside of the mounting frame 6, a third elastic component 194 fixedly connected to the side of the second piston plate 192, and the other end of the third elastic component 194 fixedly connected inside the second piston frame 191.
[0033] The second piston rod 193 has a sliding hole 196 on its outer side. A contact slide rod 197 is slidably connected in the sliding hole 196. A limit plate 198 is fixedly connected to the front side of the contact slide rod 197. Two fourth elastic components 199 are fixedly connected to the back side of the limit plate 198. The fourth elastic components 199 are fixedly connected to the outside of the second piston rod 193. The back side of the contact slide rod 197 is tapered. The contact slide rod 197 is slidably disposed between the connecting racks 20.
[0034] When the control block 195 moves to the left, it will compress the gas in the second piston frame 191 through the second piston rod 193 and the second piston plate 192. The gas is transferred to the first piston frame 171 through the intermediate tube 18, controlling the change of air pressure in the first piston frame 171. Under the action of the control block 195, the contact slide rod 197 moves forward by the compression of the connecting rack 20. After passing the connecting teeth, it is assisted by the fourth elastic component 199 to reset, so that the movement range of the control block 195 can be clearly judged.
[0035] Working principle and usage: The patient sits on the seat 8, placing both feet stably in the designated positions on the device. Through coordinated effort of the hands and legs, the patient controls the rotating contact frame 13 to perform targeted lumbar rehabilitation exercises. The rotating contact frame 13 precisely controls the rotation of the rotating rod 111 around the support pin 112 via the sliding block 114. This action drives the connecting rod 1503 to move synchronously, while the compression plate 1502 moves upward. During the movement of the compression plate 1502, the gas in the upper part of the compressed air storage cylinder 1501 is discharged through the connecting air hole 1507. Since the size of the connecting air hole 1507 limits the flow speed of the gas, the movement of the compression plate 1502 is subject to resistance from the air pressure, thus adding appropriate load to the lumbar rehabilitation exercises. When the patient performs the lumbar rehabilitation exercises slowly, the resistance will decrease accordingly, ensuring that it does not exceed the patient's tolerance limit and avoid causing injury. After completing one lumbar spine upward push rehabilitation exercise, as the compression plate 1502 moves downward, the gas in the lower air chamber of the air storage cylinder 1501 is discharged, which also increases the resistance to the downward movement of the compression plate 1502 and the rotating contact frame 13. This allows for effective weight-bearing exercise during the lumbar spine downward bending process, while preventing the rotating contact frame 13 from falling or shaking at will, ensuring the safety of the exercise. In addition, the patient can make fine adjustments by holding the control block 195. When the control block 195 moves to the left, the gas in the second piston frame 191 is squeezed by the second piston rod 193 and the second piston plate 192. The gas is transferred to the first piston frame 171 through the intermediate tube 18. The increased air pressure inside the first piston frame 171 controls the two first piston plates 172 to move away from each other, and then precisely controls the movement of the sealing plate 174 through the first piston rod 173. The movement of the sealing plate 174 blocks the connecting air hole 1507, further reducing the gas flow speed and increasing the pressure required for the extrusion plate 1502 to expel the gas from the air storage cylinder 1501. This allows the patient to flexibly adjust the load according to the needs of lumbar spine rehabilitation, ensuring that the rotation process of the rotating contact frame 13 is smooth and controllable. Even if there is a situation where it cannot be precisely controlled, it will not cause injury, thus achieving a more ideal safety performance.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
