Description

Technical Field

[0001] This invention relates to the field of medical rehabilitation, and in particular to a lumbar disc rehabilitation device based on exoskeleton dynamic support and seated traction. Background Technology

[0002] Lumbar disc herniation is a common spinal disease, often caused by prolonged poor posture, strain, or degenerative changes, leading to rupture of the annulus fibrosus and protrusion of the nucleus pulposus, which compresses nerve roots and causes symptoms such as pain and numbness. Traditional treatments include medication, physical traction, and surgery. Traction therapy is an important conservative treatment method, relieving symptoms by stretching the intervertebral space and reducing pressure on the intervertebral disc.

[0003] Currently, most lumbar traction devices on the market are horizontal traction beds or vertical traction devices, requiring users to lie down or stand. This makes it impossible to continuously perform traction rehabilitation in everyday sitting positions such as while working or driving, leading to difficulties in balancing treatment with daily life and work. Furthermore, some existing sitting traction devices use rigid support or binding fixation, such as fixing the pelvis or shoulder with straps before traction. Prolonged use can easily cause local pressure discomfort and poor blood circulation, resulting in a poor user experience and making long-term use difficult.

[0004] On the other hand, physiotherapy devices targeting the lumbar spine (such as massagers and heating pads) typically have limited functionality. While they can relieve muscle fatigue, they lack continuous and precise traction support, failing to fundamentally improve the stress state of the intervertebral discs. How to organically combine seated traction with physiotherapy functions to achieve comfortable, dynamic, and sustainable rehabilitation support has become a pressing technical problem to be solved in this field.

[0005] Based on this, the present invention proposes a lumbar disc rehabilitation device based on exoskeleton dynamic support and seated traction, aiming to provide users with a rehabilitation device that is suitable for daily seated scenarios, has both dynamic traction and physiotherapy functions, is highly comfortable, and is easy to adjust. Summary of the Invention

[0006] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, one object of the present invention is to provide a lumbar disc rehabilitation device based on exoskeleton dynamic support and seated traction.

[0007] The technical solution of the present invention is as follows: a lumbar intervertebral disc rehabilitation device based on exoskeleton dynamic support and seated traction, characterized in that it includes: a foldable support frame and a massage and heat therapy device that can be detachably installed on the support frame; The support frame includes a horizontal support rod and two vertical support components; the horizontal support rod is adjustable in length and retraction; the two vertical support components are respectively connected to the left and right sides of the horizontal support rod. Each vertical support assembly includes a vertical support rod and an underarm support member; the bottom of the vertical support rod is connected to the horizontal support rod via a universal damping hinge structure, allowing the vertical support rod to rotate in multiple directions with damping relative to the horizontal support rod; the vertical support rod itself can extend and retract along its own length, and the vertical support rod has an elastic element inside, so that the top of the vertical support rod can provide elastic floating support; the underarm support member is detachably connected to the top of the vertical support rod, and the underarm support member can rotate left and right with damping relative to the vertical support rod; The massage and heat therapy unit includes a lifting rod and a massage and heat therapy device body; the lifting rod can extend and retract along its own length, and the bottom of the lifting rod is detachably mounted on the horizontal support rod; the massage and heat therapy device body is located at the top of the lifting rod, and the massage and heat therapy device body is provided with a massage and heat therapy element for vibration massage and heat therapy, a controller and a display screen, and the massage and heat therapy element and the display screen are electrically connected to the controller.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Dynamic adaptive traction: Through a vertical support rod with multi-directional damping rotation and built-in elastic elements, combined with a universal damping hinge structure, flexible and dynamic traction of the human lumbar spine is achieved in a sitting position. The support can be adaptively adjusted with slight body movements, improving the comfort of long-term use and solving the problems of strong restraint and poor user compliance of traditional rigid traction equipment.

[0009] 2.

Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of the indicated features.

[0020] Please refer to the attached diagram below. Figures 1-3 This invention describes a lumbar disc rehabilitation device based on exoskeleton dynamic support and seated traction according to an embodiment of the present invention.

[0021] like Figure 1 As shown, the lumbar disc rehabilitation device includes a foldable support frame 1 and a massage and heat therapy device 2 that is detachably mounted on the support frame 1.

[0022] The support frame 1 includes a horizontal support rod 11 and two vertical support components. The horizontal support rod 11 is adjustable along its length to accommodate different user body widths or seat widths. The two vertical support components are connected to the left and right sides of the horizontal support rod 11 respectively to provide underarm support.

[0023] Each vertical support assembly includes a vertical support rod 12 and an underarm support 13. The bottom of the vertical support rod 12 is connected to the horizontal support rod 11 via a universal damping hinge structure, allowing the vertical support rod 12 to rotate in multiple directions with damping relative to the horizontal support rod 11. That is, when the user leans forward, backward, or moves slightly to the left or right, the support rod can swing accordingly, while providing a certain amount of damping feedback to prevent excessive swaying.

[0024] The vertical support rod 12 is extendable along its length to accommodate users of different heights. An elastic element, such as a spring, is incorporated within the vertical support rod 12, allowing the top of the rod to provide flexible, floating support rather than rigid support. This creates a flexible, dynamic support effect that follows subtle movements of the body when the user leans against it under their armpits, enhancing comfort.

[0025] The underarm support 13 is detachably connected to the top of the vertical support rod 12, and the underarm support 13 can rotate left and right with damping relative to the vertical support rod 12, so that the underarm support can better fit the user's shoulder curve.

[0026] The massage and heating unit includes a lifting rod 21 and a massage and heating device body 22. The lifting rod 21 is extendable along its length to accommodate different lumbar spine positions of users. The bottom of the lifting rod 21 is detachably mounted on a horizontal support rod 11, typically located in the middle area of ​​the horizontal support rod 11. The massage and heating device body 22 is located at the top of the lifting rod 21 and includes a massage and heating element 23 for vibration massage and heating, a controller, and a display screen. The massage and heating element 23 and the display screen are electrically connected to the controller, allowing the user to select massage modes, adjust heating temperature, set usage time, etc., via the controller; relevant information is displayed on the display screen.

[0027] When using this rehabilitation device, the support frame 1 is placed behind the seat, with the horizontal support rod 11 positioned horizontally behind the user's hip bone, and the two vertical support components extending upwards to the user's armpits. The user rests their armpits on the armpit support 13, achieving lumbar traction in a seated position through their own body weight. Simultaneously, the massage and heat therapy device body 22 is adjusted via the lifting rod 21 to fit snugly against the user's lumbar spine, activating the vibration and heat therapy functions to provide physical therapy to the lumbar intervertebral discs and surrounding muscles. The elastic floating support and omnidirectional damping rotation structure of the vertical support rod 12 allow the user to move their body slightly in scenarios such as office work and driving, while the support frame 1 can dynamically adjust accordingly, maintaining the traction effect while avoiding stiffness and discomfort.

[0028] Therefore, the lumbar disc rehabilitation device provided in this embodiment, through the foldable, multi-directional damped rotation and elastic floating support frame 1, achieves continuous, dynamic and comfortable traction of the lumbar spine in a sitting position; through the height and position adjustable massage and heat therapy unit, it achieves precise physiotherapy of the lumbar lesion site; the overall structure is compact and easy to use in daily scenarios such as office work and driving, which helps users to adhere to long-term rehabilitation training and effectively relieve and prevent lumbar disc diseases.

[0029] In some embodiments, the top of the underarm support 13 has a downwardly recessed arc-shaped support groove. The shape of this arc-shaped support groove conforms to the contour of the lower part of the human shoulder, which can better support the underarm area, increase the contact area, distribute pressure, and improve support comfort and stability.

[0030] In some embodiments, the underarm support 13 is provided with an adjustable shoulder strap 14. The shoulder strap 14 can pass over the user's shoulder to more securely fit the underarm support 13 under the armpit, preventing the support from slipping during body movement, which is especially suitable for driving or use scenarios with a large range of body movements.

[0031] In some embodiments, the underarm support 13 has a mounting hole at its bottom, and a first rubber ring is fitted onto the top of the vertical support rod 12. The underarm support 13 is detachably fitted onto the top of the vertical support rod 12 through the mounting hole. The first rubber ring provides a certain amount of frictional damping, allowing the underarm support 13 to rotate left and right relative to the vertical support rod 12 with damping after being fitted onto it.

[0032] In some embodiments, the vertical support rod 12 includes a vertical outer tube 121 and a vertical inner rod 122. The elastic element is a spring disposed within the vertical outer tube 121, and the vertical inner rod 122 is inserted into the vertical outer tube 121 and connected to the spring. By adjusting the depth to which the vertical inner rod 122 extends into the vertical outer tube 121, the overall length of the vertical support rod 12 can be changed. The spring provides elastic restoring force in both compressed and extended states, achieving vertical elastic floating support.

[0033] In some embodiments, the transverse support rod 11 includes a transverse outer tube 111 and a transverse inner rod 112. A second rubber ring is fitted on a portion of the transverse inner rod 112, and a thread is provided on the other portion. The transverse inner rod 112 is inserted into the transverse outer tube 111, and the two are threadedly connected with the second rubber ring pressed between them, so that the relative extension length and relative damping rotation of the transverse outer tube 111 and the transverse inner rod 112 can be adjusted. By screwing the transverse inner rod 112, its insertion depth into the transverse outer tube 111 can be changed, thereby adjusting the overall width of the transverse support rod 11. The frictional force generated by the compression of the second rubber ring can provide a certain rotational damping after adjustment, so that the transverse support rod 11 will not easily rotate under slight force, maintaining structural stability.

[0034] In some embodiments, the universal damping hinge structure includes a first connector 15, a second connector 16, and a damping plate 17. The first connector 15 is located at the bottom of the vertical support rod 12, and the second connector 16 is located at one end of the transverse outer tube 111 or one end of the transverse inner rod 112. The two ends of the damping plate 17 are respectively damped hinged to the first connector 15 and the second connector 16 via bolts and nuts. By adjusting the tightness of the bolts and nuts, the frictional force at the hinge can be changed, thereby adjusting the damping magnitude when the vertical support rod 12 rotates relative to the transverse support rod 11, achieving adjustable multi-directional damping rotation.

[0035] In some embodiments, the bottom of the lifting rod 21 has an open arc-shaped retaining sleeve 211, and the retaining sleeve 211 is provided with a fastening bolt 212. The retaining sleeve 211 can be detachably locked onto the transverse support rod 11, and the fastening bolt 212 is used to adjust the rotational damping force between the retaining sleeve 211 and the transverse support rod 11. This structure allows the massage and heating unit to slide left and right along the transverse support rod 11 to adjust its position, and can also lock its position by the fastening bolt 212. It also allows for the adjustment of the pitch angle of the lifting rod 21 relative to the transverse support rod 11 to accommodate the lumbar curvature of different users.

[0036] In some embodiments, the massage heat therapy device body 22 is provided with an elastic strap for connecting to the body. In summer or when clothing is thin, the elastic strap can be used to more tightly bind and fix the massage heat therapy device body 22 to the lumbar spine to ensure the therapeutic effect; in winter or when using the support frame 1, the elastic strap can be omitted, and the device can be positioned directly through the support frame 1.

[0037] In some embodiments, the massage heating element 23 is equipped with a vibration motor and a heating element, and the massage heating element 23 is connected to the massage heating device body 22 via a telescopic soft rubber component. The telescopic soft rubber component has a certain degree of elasticity and deformation capability, allowing the massage heating element 23 to float slightly, better conforming to the curve of the human lumbar spine, while buffering vibration and improving user comfort.

[0038] In summary, this device has the following characteristics: 1. Dynamic adaptive traction: The vertical support rod 12, which can rotate in multiple directions with built-in elastic elements, combined with the universal damping hinge structure, realizes flexible and dynamic traction of the human lumbar spine in a sitting position. The support can be adaptively adjusted with slight body movements, improving the comfort of long-term use and solving the problems of strong restraint and poor user compliance of traditional rigid traction equipment.

[0039] 2. Seated integrated physiotherapy: Through a detachable, height- and position-adjustable massage and heat therapy unit, it can perform vibration massage and heat therapy on lumbar spine lesions while performing seated traction. It has a high degree of functional integration and meets the needs of users to work and rehabilitate at the same time in daily scenarios such as office work and driving.

[0040] 3. Strong human-machine adaptability: Through multi-level telescopic adjustment of the horizontal, vertical and lifting rods 21, as well as the adjustable angle and position design of the underarm support 13 and massage and heat therapy unit, the rehabilitation device can flexibly adapt to users of different heights, body widths and sitting postures, improving the universality of the product and user experience.

[0041] 4. Compact and portable structure: The foldable support frame 1 and detachable unit design allow the entire device to be folded up when not in use, reducing its size and making it easy to carry and store, suitable for use in multiple scenarios.

[0042] Although some embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations of these embodiments without departing from the principles and spirit of the present invention are within the scope of protection of the claims of the present invention.
