Abstract
Description
Technical Field
[0001] This invention relates to the field of biological rehabilitation technology, specifically a spinal rehabilitation device suitable for people of different weights. Background Technology
[0002] Currently, there are many methods for treating lumbar spine diseases in clinical practice. Treatment beds can not only be used for the rehabilitation of shoulder and back pain, numbness in the limbs, or pain after the period of lumbar disc herniation, but are also particularly suitable for people who lack exercise, cannot exercise actively, or are older or in a sub-healthy state.
[0003] Existing treatment beds lack components such as tension sensors and floor scales, making it impossible for them to make timely angle limits and locks based on people of different weights during self-traction. Summary of the Invention
[0004] The purpose of this invention is to provide a spinal rehabilitation device to solve the problem that it is impossible to make timely positioning and angle locking according to people of different weights during self-traction.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a spinal rehabilitation device, comprising a bed frame with a bed board, an arc-shaped plate for positioning the bed frame and a shell, wherein the arc-shaped plate and the shell cooperate with each other, and further comprising a lying-flat assist mechanism, a lying-flat movement mechanism and a locking mechanism, wherein a floor scale is provided at the bottom of the shell.
[0006] Compared with the prior art, the beneficial effects of the present invention are:
[0007] Through self-weight dynamic traction, fan-shaped spinal rotation and swaying, restoration of physiological curvature, repositioning and cyclic inversion, and aerobic passive exercise, relative traction and twisting are performed, massaging the nerve roots, clearing the meridians and blood circulation and nerve conduction, opening the meridians, straightening the intervertebral joint relationship, and restoring the normal physiological curvature of the spine to slow down the degenerative changes of the spine, promote the oxygenation function of the heart and lungs and blood circulation, accelerate metabolism and delay the aging of various tissues and organs in the body. It can be used for people of different weights.
[0008] When a heavier person lies down, the bed frame tilt angle is set within a range of maximum rotation angles based on their weight. Therefore, when a heavier person is in an inverted tilted position, if the curved plate rotates to the maximum tension range but the angle has not reached the specified value, the electric rotating rod will lock at the angle to achieve a limiting effect, thus ensuring safety during treatment.

[0019] Please see Figure 1-9 This invention provides a technical solution: a spinal rehabilitation device, comprising a bed frame 1 with a bed board 2, an arc-shaped plate 3 for positioning the bed frame 1, and a housing 4 for adjusting the position of the arc-shaped plate 3. The arc-shaped plate 3 is installed on the bottom surface of the bed frame 1. Slots 30 for installing the arc-shaped plate 3 are provided on both side walls of the housing 4, making the housing 4 U-shaped overall. The arc-shaped plate 3 is entirely placed within the slots 30 and can rotate within the housing 4. A floor scale 29 is fitted at the bottom of the housing 4 to support the bed frame 1 and to measure the overall weight.
[0020] The spinal rehabilitation device also includes a lying-down assist mechanism 6, a lying-down movement mechanism 7, and a locking mechanism 8.
[0021] The lying-down assistive mechanism 6 includes an ankle fixator 9. A tension sensor 31 is installed inside the ankle fixator 9. When one side of the ankle fixator 9 is raised and the user's ankle is secured, the tension sensor 31 measures the tension applied to the ankle fixator 9. The ankle fixator 9 is mounted on the rear end of the bed frame 1, away from the bed board 2. Symmetrical positioning grooves 10 conform to the shape of the ankle are provided on the ankle fixator 9, and locking straps 11 are provided on the positioning grooves 10 that can be adjusted according to the size of the ankle. A swing motor 5, model 57BL120L2, is installed on the bottom surface of the bed frame 1 to rotate the ankle fixator 9, thereby driving the patient's legs to swing left and right.
[0022] The patient lies on the bed board 2, placing their ankles in the positioning slots 10 of the ankle fixator 9. The locking straps 11 are adjusted and locked according to different ankle sizes. After securing both feet, the ankle fixator 9 swings in a fan-shaped motion from side to side, moving the feet upwards through the lumbar, thoracic, and cervical vertebrae. This causes each vertebra to undergo a semi-rotational twist, correcting facet joint disorders, relieving soft tissue contractures around the spine, repositioning intervertebral discs, and traction on the nerve roots in the intervertebral foramina. This utilizes the patient's own weight to traction the spine, naturally relaxing muscles and ligaments, relieving muscle stress, widening the intervertebral space, and reducing the load on the intervertebral joint structures. The locking straps 11 are made of nylon and have adjustable elasticity to accommodate patients with different foot shapes.
[0023] The lying-flat moving mechanism 7 includes a bed board 2 composed of multiple bed rods 12 with equal spacing. The bottom wall of the bed rods 12 is symmetrically provided with a first slide rail 13 about the central axis of the bed rods 12. The bottom of the first slide rail 13 is provided with sliders 14 at equal intervals. The upper end of the slider 14 is provided with a first slide groove 15 that is slidably connected to the first slide rail 13. The lower end of the slider 14 is provided with a second slide groove 16. The first slide groove 15 and the second slide groove 16 are intersected on different horizontal planes. The multiple second slide grooves 16 are connected by a second slide rail 17. The inner walls of the bed frame 1 are provided with grooves 18 that limit the bed board 2.
[0024] The second slide groove 16 under the bed board 2 can slide on the second slide rail 17, and the first slide rail 13 can slide on the first slide groove 15, satisfying the slight movement of the bed rod 12 during self-weight dynamic traction and spinal rotation. The swinging gradually widens the intervertebral space, slowly realigning the misaligned spine. After increasing the activity of the soft tissues around the intervertebral discs, it improves the blood circulation of the soft tissues, increases the water content of the nucleus pulposus of the lumbar intervertebral discs, restores the normal alignment of the spine, and strengthens the stability of the spine.
[0025] The cross-sectional shape of the first slide rail 13, the second slide rail 17, the first slide groove 15, and the second slide groove 16 is all designed as an I-shape, specifically a structure that is wider at the top and bottom and narrower in the middle. This ensures the stability of the first slide rail 13 and the second slide rail 17 when sliding under the bed board 2.
[0026] The locking mechanism 8 includes a central shaft 19, which extends through the center of the arc-shaped plate 3 to both sides of the interior of the housing 4, and bearings are provided at the connection points with the housing 4, allowing the central shaft 19 to rotate along the housing 4 while remaining fixed relative to the arc-shaped plate 3. A cross-shaped insert 20 passes through the interior of the central shaft 19, and a cross groove 21 for mounting the cross-shaped insert 20 is provided at the center of the central shaft 19. A housing 22 is provided at the rear of the housing 4, and an electric rotating rod 23 for driving the cross-shaped insert 20 to rotate is provided inside the housing 22. By activating the electric rotating rod 23, the cross-shaped insert 20 drives the arc-shaped plate 3 and the bed frame 1 to rotate.
[0027] The cross-shaped insert 20 can be selected with other numbers of protruding inserts depending on the actual situation. At the same time, the shape of the slot also needs to be adjusted according to the actual selected insert.
[0028] The main unit is first configured on a PC, including using the weighbridge 29 to calculate the maximum traction force and adjust the traction angle. The main unit connects to the electrical components of the device. During the use of the main unit, the inverted tilt angle of the device is adjusted by the electric rotating rod 23 and the swing motor 5 through preset programs or manual operation. By changing various postures from horizontal to different inverted angles and back to horizontal, the venous blood return of the lower limbs is enhanced, the blood supply to the brain is increased, and the elasticity of blood vessels is improved through continuous expansion and contraction, promoting blood circulation. The curved plate 3 drives the bed frame 1 to rotate to different angles under the rotation of the central axis 19, and the mechanical power and gravity can easily increase the oxygen content of the brain. When people of normal weight use the device, the locking mechanism will not be activated. When a heavier person lies flat, the tilt angle of the bed frame 1 has a maximum rotation angle range according to the weight. Therefore, when a heavier person is in the tilted inverted state, when the curved plate 3 rotates to the maximum traction force of the tension sensor 31, but does not reach the specified angle, the electric rotating rod 23 locks.
[0029] A leg heating support 24 is installed on the bed frame 1 near the bed board 2 and the ankle fixation device 9. A lumbar heating pad 25 and a neck heating pad 26 are respectively installed at both ends of the bed board 2. The leg heating support 24, lumbar heating pad 25, and neck heating pad 26 are all made of graphene heating material. Under the conditions of warmth, traction, osteopathy, and movement provided by the leg heating support 24, lumbar heating pad 25, and neck heating pad 26, the undesirable state of the spine is fundamentally corrected, assisting in the restoration of the spine's normal physiological curvature. The necessary warm environment is provided to support the restoration of the spine's normal physiological curvature. A special ceramic silica powder far-infrared generator filters out harmful and useless rays, generating beneficial far-infrared rays that can penetrate 3 cm into the human body, which can reduce inflammation, relieve pain, promote blood circulation, and improve the body's immunity.
[0030] An emergency button 27 is installed on one side wall of the bed frame 1. The emergency button 27 is connected to an external power source and the main unit for power outage. A human-machine interface 28 is installed on the side away from the emergency button 27. The human-machine interface 28 can be operated via a computer platform, mobile APP, WeChat official account, or remote control. It can collect and summarize other health information such as changes in heart rate, blood pressure, and blood sugar. By analyzing the changes in health information during the treatment process, the differences in individual recovery can be analyzed.
[0031] This device is suitable for people of all weights. The scale 29 is located at the bottom of the bed and is used for weighing the user. Its main function is to calculate the maximum traction force (e.g., at 30 degrees) for people of different weights. When the user uses the device, it can rotate to the maximum angle of 30 degrees and record the measured value of the tension sensor 31. When the user actually uses the device, if the device rotates to 28 degrees but has not reached 30 degrees, and the tension sensor 31 has already reached the maximum tension value, the user's traction angle will be automatically adjusted to 28 degrees, and the maximum angle and maximum traction force will not exist simultaneously for a specified time.
[0032] In custom mode, a fixed traction force (e.g., 30 Newtons) can be preset. The system will calculate the approximate angle to be raised or lowered based on the user's weight, and then make fine adjustments through the tension sensor 31 to achieve the traction force of 30 Newtons. The tension sensor 31 is located behind the foot strap and mainly displays the user's current traction force in real time.
[0033] Working principle: Through mechanical power, the body is driven to perform passive aerobic exercise in a reverse posture. Each combing is equivalent to the exercise of jogging 2 to 3 kilometers, which better consumes accumulated fat and carbohydrates and promotes the body's metabolism. According to biomedical principles, through mechanical power, the body is driven to perform passive aerobic exercise. The amount of exercise in one spinal combing is equivalent to jogging 2,000 to 3,000 meters, which better consumes accumulated fat and carbohydrates and promotes the body's metabolism.
[0034] When using the main unit for massage, the change in body position, combined with passive aerobic exercise, allows the internal organs to passively peristalse and pat within the cavities. This is a gentle "massage" of the internal organs, which is both comfortable and improves their function, directly enhancing blood circulation.
[0035] It dilates capillaries, improves microcirculation, and nourishes peripheral nerves.
[0036] From a biomechanical perspective, when the head is down and the feet are up, blood flow to the brain increases due to gravity, causing blood vessels in the head to dilate and increasing blood oxygen levels in the brain. When the body lies flat, blood returns to the heart, allowing the capillaries in the brain to return to normal. This repeated expansion and contraction fully exercises the capillaries, increasing their elasticity. The blood vessel walls are flushed and cleansed, improving the elasticity and microcirculation of the blood vessels in the head and increasing the nutrition to the peripheral nerves in the head, hands, and feet.
[0037] Relax and exercise your waist and abdominal muscles
[0038] Research from the Department of Mechanobiology and Biomechanics at Beijing University of Aeronautics and Astronautics has found that when the host is inverted by 1-27 degrees and the swing speed is below 120 times per minute, it can fully exercise the muscles on both sides of the spine, restore their elasticity and tension, and thus better hold the spine and joints.
