Description

Technical Field

[0001] This utility model relates to the field of rehabilitation and physiotherapy technology, specifically a foldable, dynamic guided swallow-flying lumbar disc physiotherapy bed. Background Technology

[0002] Lumbar disc disease, caused by disc degeneration and herniated nucleus pulposus compressing nerves, leads to lower back and leg pain. Traditional treatments primarily involve analgesic medication and surgical intervention, but these have limitations such as high recurrence rates and significant trauma risks. Medical research indicates that the "swallow flight" exercise, which generates negative pressure through lumbar extension, can promote nucleus pulposus retraction; however, its practicality is limited by the risk of secondary lumbar spine injury due to insufficient muscle strength or improper technique. Existing physiotherapy beds mostly employ fixed structures, are bulky, and cannot be folded, limiting their use at home. While some devices incorporate hydraulic drives, they suffer from complex operation and high maintenance costs. Furthermore, traditional physiotherapy beds lack dynamic guidance and adaptive adjustment functions, making them unsuitable for patients of different body types and resulting in inconsistent therapeutic effects.

[0003] Therefore, there is an urgent need for a physiotherapy device that combines safe dynamic traction, precise adaptation, and convenient storage to overcome traditional technical bottlenecks and achieve efficient home-based rehabilitation. Utility Model Content

[0004] In order to solve the problems of the prior art, this utility model provides a foldable, dynamically guided, swallow-flying lumbar disc physiotherapy bed.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: a foldable, dynamically guided, swallow-flying lumbar disc physiotherapy bed, comprising:

[0006] Box-type bed base;

[0007] Symmetrical lever-supported legs are mirror-symmetrically arranged on both sides of the four corners of the bed base. The upper end of the legs is equipped with guide wheels, the lower end with casters, and the middle part of the legs is hinged to the bed base through lever bearings.

[0008] The hinged three-body linkage frame includes a middle small platform, an upper frame and a lower frame. An electric push rod is fixedly connected to the bottom of the middle small platform. The upper frame and the lower frame are respectively hinged to the two ends of the middle small platform by hinges.

[0009] The bottom surfaces of the upper frame and the lower frame are equipped with reinforcing baffles, and guide holes are opened on the reinforcing baffles. The guide wheels of the symmetrical lever load-bearing legs are embedded in the guide holes.

[0010] When the electric push rod drives the three-body linkage frame to move continuously up and down, the guide wheel slides along the guide hole to resolve the small displacement between the support leg and the bottom surface of the frame.

[0011] In this application, a symmetrical lever-type support leg and a hinged three-body linkage frame are synergistically designed and combined with an electric push rod drive to achieve both precise physiotherapy and convenient storage for lumbar disc diseases. Its core function is to passively complete the "swallow flight" movement through mechanical guidance, simulating the natural undulating motion of the lumbar spine, dispersing the load on the lumbar spine and generating a negative pressure effect to promote the return and repair of the nucleus pulposus. Simultaneously, the support leg guide wheels slide along guide holes to dissipate displacement, ensuring smooth and safe movement. When the device is folded up, the support legs stand side by side and the casters touch the ground, forming a compact box structure that saves space and facilitates movement. The telescopic frame, sliding mask, and gently sloping end design adapt to different body types, and the screen control system supports intelligent parameter adjustment, balancing personalized physiotherapy with ease of operation. This bed empowers traditional rehabilitation exercises with technology, avoiding the risks of active exercise and overcoming the limitations of traditional physiotherapy equipment such as large footprint and limited functionality, significantly improving the efficiency of home rehabilitation for lumbar disc diseases.

[0012] In one specific implementation, load-bearing protrusions are fixedly connected to both sides of the bed base, and leg limiting blocks are fixedly connected to the lower ends of both sides of the bed base. When the symmetrical lever load-bearing legs are extended, their lower ends abut against the load-bearing protrusions. When the symmetrical lever load-bearing legs are retracted, the three-body linkage frame is lifted to make the legs stand side by side and abut against one side of the leg limiting block, while the casters touch the ground.

[0013] The reinforced baffle is also equipped with positioning holes. When retracted, the outrigger position is locked by inserting a pull rod into the positioning hole.

[0014] In one specific embodiment, a guide rectangular hole is provided in the middle of the upper frame, on which a face mask that can slide longitudinally is installed. A straight row of needle roller bearings is provided on the lower outer side of the face mask, and a guide limiting baffle is provided on the lower inner side.

[0015] In one specific implementation, the distal ends of the upper frame and the lower frame are respectively provided with telescopic adjustment parts, and the telescopic adjustment parts are fixed in position by telescopic rods below the frames.

[0016] The lower body frame has a diffuse arc-shaped structure at its ends.

[0017] In one specific implementation, the top of the upper frame is equipped with a tilting screen control box, which integrates speed, amplitude, and time control modules as well as dynamic sensing display function.

[0018] In one specific implementation, the electric push rod has a safety margin of mm at both ends of its stroke, and a support pad is provided at the fastening connection with the central small platform.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses an electric push rod to drive a three-body linkage frame to simulate the "swallow flying" movement, achieving passive dynamic traction of the lumbar spine at a constant frequency (1-3Hz) and adjustable amplitude (10°-30°), creating an intermittent negative pressure effect in the lumbar and abdominal region (measured negative pressure values ​​reach -50 to -100Pa), which promotes the return of the herniated nucleus pulposus to the intervertebral space. Clinical trials show that after 4 weeks of use for an average of 20 minutes per day, the average reduction rate of lumbar disc herniation volume reached 42%. Zero-load physiotherapy design: when the patient lies prone, the upper body and lower limb frame bear the entire movement load, and the force on the lumbar spine is <5N, which is only 1 / 80 of that of the traditional active "swallow flying" movement, completely avoiding the risk of secondary injury caused by excessive tension in the lumbar spine.

[0021] 2. Through the linkage and folding mechanism of symmetrical lever legs, the size of the bed after folding is only 40% of the unfolded state. It can be stored upright against the wall or placed in the gap of a regular wardrobe. Lifting the frame triggers the legs to stand up automatically. After the casters touch the ground, it can be pushed by one person. It breaks through the limitations of traditional physiotherapy equipment that is bulky and difficult to move, and is suitable for diverse scenarios such as home and community clinics.

[0022] 3. The tilting screen control box integrates preset speed, amplitude, and time parameters (such as "relaxation program for the elderly" and "enhancing program for young adults"), supports voice guidance and real-time motion data feedback (such as lumbar curvature and pressure distribution), reducing the operating threshold by 80%; the telescopic adjustment section covers a height range of 140-200cm, the mask sliding mechanism (displacement ±90mm) precisely matches the torso length, and the gentle arc end relieves foot pressure, ensuring that more than 95% of users obtain a comfortable fit with "zero adjustment error".

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0029] like Figures 1 to 4 The foldable, dynamically guided, swallow-flying lumbar disc therapy bed shown includes:

[0030] Box-type bed base 1;

[0031] Symmetrical lever-bearing support legs 2 are mirror-symmetrically arranged on both sides of the four corners of the bed base 1. The upper end of the support leg 2 is provided with a guide wheel 21, the lower end is provided with a caster 22, and the middle part of the support leg 2 is hinged to the bed base 1 through a lever bearing 23.

[0032] The hinged three-body linkage frame 3 includes a middle small platform 31, an upper frame 32 and a lower frame 33. An electric push rod 4 is fixedly connected to the bottom of the middle small platform 31. The upper frame 32 and the lower frame 33 are respectively hinged to the two ends of the middle small platform 31 through hinges 34.

[0033] The bottom surfaces of the upper frame 32 and the lower frame 33 are provided with reinforcing baffles 35, and the reinforcing baffles 35 are provided with guide elongated holes 351. The guide wheels 21 of the symmetrical lever load-bearing legs 2 are embedded in the guide elongated holes 351.

[0034] When the electric push rod 4 drives the three-body linkage frame 3 to move continuously up and down, the guide wheel 21 slides along the guide hole 351 to resolve the small displacement between the support leg 2 and the bottom surface of the frame.

[0035] When the symmetrical lever load-bearing support leg 2 is extended, its lower end abuts against the load-bearing protrusion 9 of the bed base 1. When it is retracted, the support leg 2 is made to stand side by lifting the three-body linkage frame 3, and the caster 22 touches the ground.

[0036] The reinforced baffle 35 is also provided with a positioning hole 352. After being retracted, the position of the outrigger 2 is locked by inserting the pull rod 5 into the positioning hole 352.

[0037] The upper frame 32 has a guide rectangular hole 36 in the middle, on which a mask 6 that can slide longitudinally is installed. A straight row of needle roller bearings 61 is provided on the lower outer side of the mask 6, and a guide limit baffle 62 is provided on the lower inner side.

[0038] The upper frame 32 and the lower frame 33 are respectively provided with telescopic adjustment parts 37 at their far ends. The telescopic adjustment parts 37 are fixed in position by telescopic rods 7 below the frame.

[0039] The lower body frame 33 has a diffuse arc-shaped structure 38 at its end.

[0040] The top of the upper frame 32 is equipped with a tilting screen control box 8, which integrates speed, amplitude, and time control modules as well as dynamic sensing display function.

[0041] The electric push rod 4 has a 10mm safety margin at both ends of its stroke, and a lifting reinforcement pad 41 is provided at the fastening connection with the small central platform 31.

[0042] In summary, this utility model has the following working principle:

[0043] Folding and storage process

[0044] Step-by-step instructions:

[0045] Confirm safe status

[0046] After the physiotherapy session, turn off the power via the control box 8 to ensure that the electric push rod 4 stops running and the small platform 31 in the middle is in the lowest position (the lifting pad 41 contacts the base, and the green indicator light illuminates).

[0047] Lifting the frame triggers the retraction of the outriggers.

[0048] Hold the far ends of the upper frame 32 and the lower frame 33 with both hands and lift them upwards at the same time, causing the folding three-body linkage frame 3 to fold upwards around the central small platform 31.

[0049] Linkage effect: The symmetrical lever-supported legs 2 are lifted and pulled by the frame, and mirror-close inward with the lever bearing 23 as the fulcrum. The casters 22 at the lower end of the legs automatically touch the ground and detach from the bed load-bearing protrusions 9.

[0050] Lock out the position of the outriggers

[0051] Observe the positioning hole 352 on the reinforcing baffle 35, insert the pull rod 5 into the corresponding positioning hole on both sides, and push it horizontally into the locked state to ensure that the support legs 2 stand firmly.

[0052] Check movement status

[0053] Gently push the bed to confirm that the casters 22 roll smoothly. Insert the limit rod 9 into the far-end limit hole 39 to prevent the frame from unfolding accidentally. The bed will then fold into a compact box.

[0054] Effects:

[0055] Space-efficient utilization: When folded up, it occupies only 40% of the area when unfolded, making it easy to store against a wall or place between furniture.

[0056] Easy to move: With the 22 casters on the ground, it can be easily pushed by a single person, adapting to the moving needs of various scenarios such as home and clinic.

[0057] Structural stability: The mechanical locking of the pull rod 5 and the positioning hole 352 prevents the outrigger 2 from shaking, and the limit rod 9 ensures that the frame is firmly folded.

[0058] Expand the usage process

[0059] Step-by-step instructions:

[0060] Release locking device

[0061] Pull out the pull rod 5 to disengage it from the positioning hole 352, remove the limit rod 9, and release the fixed constraint between the support leg 2 and the frame.

[0062] Deploy the outriggers and frame

[0063] With both hands supporting the middle of the three-body linkage frame 3, slowly lower it to a horizontal position. The symmetrical lever load-bearing legs 2 automatically unfold under the action of gravity, and the guide wheel 21 slides outward along the guide hole 351 of the reinforcing baffle 35.

[0064] Linkage effect: The lower end of the support leg 2 abuts against the load-bearing protrusion 9 of the bed frame to form rigid support, the caster 22 is lifted off the ground and hidden, and the entire bed is placed firmly on the ground.

[0065] Adjust adaptation parameters

[0066] Telescopic adjustment section 37: According to the user's height, pull out the telescopic parts of the upper frame 32 and the lower frame 33, and fix them to the appropriate length by telescopic rod 7 (with scale markings as aid).

[0067] Mask 6 positioning: The mask 6 slides along the guide rectangular hole 36, the straight roller bearing 61 reduces friction, and the guide limit baffle 62 prevents displacement, so that the center of the mask is aligned with the user's shoulder.

[0068] Set physiotherapy parameters

[0069] The speed (levels 1-5), amplitude (10°-30°), and time (10-30 minutes) can be set via the tilting screen control box 8, and the dynamic sensing function can be activated to monitor the motion status.

[0070] Start the physiotherapy program

[0071] The user lies prone with their waist and abdomen against the small platform 31 in the middle, and their limbs are naturally extended. The electric push rod 4 drives the frame to rise and fall continuously, starting the dynamic traction therapy.

[0072] Effects:

[0073] Rapid deployment: Folding and positioning can be completed within 3 minutes, and the mirror unfolding of the second outrigger ensures even weight distribution at four points (support force ≥150kg).

[0074] Precise fit: The telescopic adjustment part 37 and the sliding design of the mask 6 cover a height range of 140-200cm, and the gentle arc structure 38 relieves foot pressure.

[0075] Safe operation: The electric push rod 4 has a 10mm safety margin and a lifting reinforcement pad 41 to absorb impact, and the guide hole 351 resolves displacement and avoids mechanical jamming.

[0076] III. Overall Results of the Entire Process

[0077] Seamless switching between folding and unfolding: Through the mechanical linkage between the lever leg 2 and the three-body frame 3, the "working state - moving state" can be switched with one click. No tools are required for operation and it can be completed by a single person.

[0078] Maximizing therapeutic effect: The rigid support of the unfolded frame and the precise control of the electric push rod 4 ensure a constant "swallow flight" movement trajectory, uniform force on the lumbar spine (<5N), and 20 minutes of use per day can significantly relieve pain.

[0079] User-friendliness: The integrated design of the screen control box 8 lowers the operating threshold, while the casters 22 and telescopic structure make the equipment both professional and home-friendly, promoting the implementation of the "proactive health" concept.

[0080] In summary, this bed, through its ingenious folding and unfolding mechanism and intelligent control, extends lumbar disc therapy from professional medical settings to the home environment. With its high efficiency, safety, and convenience, it represents a revolutionary solution in the field of lumbar spine rehabilitation.
