[0017] The advantages of the present invention over the prior art are: 1. The present invention uses traction to restore the lumbar vertebrae, which have deviated from their normal curvature, to their normal physiological curvature. The user lies prone on a support bed. One end of a first lumbar traction belt is tied and fixed to the user's chest, and the other end is tied and fixed to a corresponding traction bracket. A second lumbar traction belt is then tied and fixed to the user's waist at one end. Each end is connected to a traction device, and both traction devices are mounted on another traction bracket. The traction devices are controlled to apply traction to the second lumbar traction belt. The two traction devices can apply the same or different traction forces, which allows for better alignment of the user's lumbar vertebrae and helps restore their normal physiological curvature. Furthermore, the traction force can be directly read from the traction device, allowing for quick determination of the applied force and effective control to prevent damage to the lumbar vertebrae caused by excessive traction. The traction device also features an adjustable inclination, allowing for adjustment to the appropriate inclination based on the user's lumbar curvature. Adjusting the inclination of the traction device also changes the inclination angle of the traction force, thereby gradually adjusting the user's lumbar vertebrae to their normal physiological curvature.

[0018] 2. The present invention also adds a neck traction device, which is correctly worn on the user's neck, and one end of the second lumbar traction belt is tied and fixed to the user's waist and connected to a traction device on both sides. The two traction devices are installed on another traction bracket. The traction device is controlled to apply traction to the second lumbar traction belt. The user's waist is acted upon by the traction force, and the torso is pulled toward the traction device, so that the neck traction belt pulls the user's neck in the opposite direction, and the user's cervical spine is pulled, thereby relieving muscle tension, reducing nerve compression, and improving the cervical spine structure.

[0019] 3. The support bed of the present invention is adjustable in length. To shorten the support bed, turn the adjustment screw clockwise. The adjustment screw screws into the adjustment support and extends toward the second spliced bed, pushing the second spliced bed away from the first spliced bed, thereby increasing the length of the support bed. To lengthen the support bed, turn the adjustment screw counterclockwise. The adjustment screw screws out of the adjustment support and move the second spliced bed closer to the first spliced bed, thereby shortening the support bed. Therefore, the support bed can be adjusted in length according to the height of different patients, making it more flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to enable people skilled in the art to better understand the technical solutions in this application, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only part of the embodiments of this application. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0023] Example 1: like Figures 1 to 9As shown, a prone lumbar traction bed comprises a support bed 1 and a traction device, the traction device comprising a first lumbar traction belt 9, a second lumbar traction belt 14, two traction devices 20, and a traction bracket 6; the two traction brackets 6 are fixedly arranged in parallel at both ends of the support bed 1 at intervals; the first lumbar traction belt 9 is tied to one traction bracket, and two traction devices 20 with adjustable inclination and directly readable traction force are installed on the other traction bracket, and the two traction devices are respectively connected to the two sides of the second lumbar traction belt 14, and apply traction force respectively.

[0024] The first and second lumbar traction belts 9, 14 are each equipped with a first adjustment strap 10 and a second adjustment strap 11. The first and second lumbar traction belts 9, 14 are secured to the user via the second adjustment straps. The first adjustment strap on the first lumbar traction belt 9 is secured to the traction support. The first adjustment strap on the second lumbar traction belt is connected to the traction device.

[0025] The first adjustment strap 10 includes a fixing strap 101, a first buckle 102, and a first adjustment strap 103. One end of the fixing strap 101 is fixedly connected to the lumbar traction strap, and the other end is equipped with the first buckle 102. One end of the first adjustment strap 103 is fixedly connected to the lumbar traction strap, and the other end is free. When the first adjustment strap 103 is required to be tied, the first adjustment strap 103 is engaged with the first buckle 102.

[0026] The second adjustment strap 11 includes a second buckle 111 and a second adjustment belt 112. The second adjustment belt 112 is connected to the lumbar traction belt. One end extends from the lumbar traction belt and is connected to the second buckle, and the other end is a free end for adjusting the width of the binding.

[0027] One structure of the first lock buckle 102 and the second lock buckle 111 includes two square frames. One structure in which the two square frames are attached to the adjustment strap can be: one end of the adjustment strap passes through the two square frames, then bends and secures to the adjustment strap body. The two square frames can move relative to the adjustment strap.

[0028] The adjusting belt is locked to the two square frames: the adjusting belt passes through the two square frames, and then the two square frames are staggered and stacked, and then the adjusting belt is bent and passed through the gap formed by the staggered two square frames, and the adjusting belt is tightened, and the two square frames clamp and fix the adjusting belt.

[0029] It should be noted that the first lumbar traction belt and the second lumbar traction belt are both existing lumbar traction belts. Lumbar traction belts are commercially available. The traction belts can be in the form of a belt and can be directly tied and fixed, or can be fixed with Velcro or other fixing methods.

[0030] The tractor can be installed at an angle of 10 to 60 degrees. You can select the appropriate angle according to your needs. The angles can be 10 degrees, 15 degrees, 20 degrees, 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, or 60 degrees. In actual use, the commonly used angles are 25 degrees, 30 degrees, 35 degrees, 40 degrees, and 45 degrees. Adjust according to different situations.

[0031] When the tractor applies traction force, the magnitude of the traction force can be viewed in real time.

[0032] A connection structure between the traction device and the second lumbar traction belt 14 is provided. A buckle 18, a pulley 19, and a traction rope 17 are added. One end of the buckle 18 is connected to the second lumbar traction belt 14, and the other end is connected to the pulley 19. One end of the traction rope 17 is connected to the traction device 20, and the other end is connected to the pulley 19 after being wound around the pulley. When the traction device applies traction, the traction rope 17 is tightly wound around the traction device.

[0033] In order to provide a comfortable feeling for the user lying on the support bed 1 , a mattress 7 is additionally installed and laid on the support bed 1 .

[0034] In some optional embodiments, a neck traction member is additionally installed. Figure 2 、 3 As shown, the neck traction member is installed at one end of the support bed 1.

[0035] like Figure 2 As shown, the neck traction device includes a support vertical rod 21, an adjustment bolt 23, a transverse rod 25, and a neck traction strap 28. An adjustment slot 22 is defined along the height of the support vertical rod 21; the adjustment bolt 23 passes through the adjustment slot 22 to clamp and secure the support vertical rod 21. The transverse rod 25 is mounted at the top of the support vertical rod 21, with hooks 26 mounted at each end. The ends of the neck traction strap 28 are connected to corresponding hooks 26.

[0036] The neck traction member is installed at the end of the support bed 1, and the height of the support vertical rod relative to the top surface of the support bed can be adjusted.

[0037] A connection structure between the support rail and the bed: a screw hole 24 is provided at the end of the bed. An adjustment bolt 23 passes through an adjustment slot 22 and is threadedly connected to the screw hole 24. When the adjustment bolt 23 is tightened, it squeezes the support rail and secures it to the bed. To adjust the height of the support rail, loosen the adjustment bolt to move the support rail vertically.

[0038] The adjusting bolt 23 may be a knob screw, and one structure of the knob screw may be a plum blossom thumb screw, a cross knob screw, or the like.

[0039] In this embodiment, in order to facilitate the connection between the neck traction belt 28 and the hook, a hanging ring 27 is additionally installed. Both ends of the neck traction belt 28 are provided with a hanging ring 27, and the neck traction belt is hung on the hook 26 through the hanging ring 27. The neck traction belt and the hanging ring can be quickly connected.

[0040] This embodiment further incorporates a reinforcement plate 33 to enhance support for the support vertical rod 21. The reinforcement plate 33 is positioned above the screw hole 24 and fixedly mounted to the end surface of the support bed. The support vertical rod 21 can be flexibly engaged with the reinforcement plate 23. When the support vertical rod 21 is subjected to tension, the reinforcement plate 23 provides support for the support vertical rod, further enhancing its stability.

[0041] In some optional embodiments, a structure in which the length of the support bed is adjustable is provided. The support bed 1 includes a first spliced bed 111, an adjusting screw 31 and a second spliced bed 112. The first spliced bed 111 is provided with a first support rod 118, a first spliced leg 115 is installed at the bottom, a first support rod 116 is installed on the first spliced leg 115, and an adjusting support 30 is installed on the first support rod 116; the second spliced bed 112 is provided with a second support rod 117, a second spliced leg 112 is installed at the bottom, the second support rod 117 is movably inserted into the first support rod 118, and a supporting base 29 is installed on the second spliced leg 112; the adjusting screw 31 is screwed together with the adjusting support 30, and then rotatably connected with the supporting base 29.

[0042] The adjusting screw 31 and the support base 29 can be connected via a bearing. The bearing can support the adjusting screw to rotate relative to the support base.

[0043] In order to facilitate the operation of the adjusting screw 31, a handle plate 32 is additionally installed, and the handle plate 32 is installed on the adjusting screw 31. By rotating the handle plate, the adjusting screw can be driven to rotate.

[0044] One way to adjust the length of the support bed: The adjusting screw 31 is rotated clockwise, and the adjusting screw 31 extends outward relative to the adjusting support 30. The adjusting screw 31 pushes the second spliced bed 112 to move, and the second spliced bed 112 drives the second support rod 117 to extend outward from the first support rod 118, thereby increasing the length of the support bed.

[0045] The adjusting screw 31 is rotated counterclockwise, and the adjusting screw 31 contracts inward relative to the adjusting support 30, and the adjusting screw 31 drives the second spliced bed 112 to move, and the second spliced bed 112 drives the second support rod 117 to extend inward toward the first support rod 118, thereby reducing the length of the support bed.

[0046] In some optional embodiments, a structure of a traction bracket is provided. The traction bracket 6 includes a crossbar 61, with two parallel and spaced vertical bars 62 mounted at spaced ends on the crossbar 61. One end of the vertical bar 62 extends upward to protrude above the top surface of the support bed 1, and the other end extends downward to connect with one end of a second reinforcing bar 64. The other end of the second reinforcing bar 64 is connected to a base plate 66, which is connected to the support bed 1 via a plurality of fourth bolts 65. The vertical bars 62 are clamped and fixed to the support bed 1 via third bolts 63.

[0047] The height that vertical rod 62 extends upward relative to the top surface of supporting bed can be 15~30cm. Commonly available height can be 15,20,25 or 30cm. It is understood that vertical rod can be height-adjusted relative to supporting bed.

[0048] It should be noted that when the support bed is installed with a mattress, the height of the vertical rod extending from the top surface of the support bed is added to the thickness of the mattress. If the thickness of the mattress is 10 cm, the height of the vertical rod extending from the top surface of the support bed is added with 10 cm to obtain the actual height of the vertical rod extending upward.

[0049] In order to facilitate placing items at the bottom of the support bed, an additional rack 5 is installed. The bottom of the support bed 1 is equipped with a rack 5, which can be used to support and place items.

[0050] In order to enhance the bearing capacity of the top of the bed, a first reinforcing rod 2 is additionally installed. A first reinforcing rod 2 is respectively installed on the side surfaces at both ends of the head of the bed.

[0051] like Figure 1 As shown, one end of the first reinforcing rod 2 is fixedly connected to the support leg of the support bed through a first bolt 3, and the other end is fixedly connected to the side of the support bed through a second bolt 4.

[0052] In some optional embodiments, a structure of a tractor is provided. Figure 4-8 As shown, the tractor 20 includes a traction force measuring piece, a rope tightener and a clamping fixture, and the two ends of the rope tightener are hingedly connected to the traction force measuring piece and the clamping fixture respectively.

[0053] The clamping fixture is used to clamp the traction bracket so that the tractor is integrally mounted on the traction bracket.

[0054] The traction force measuring piece displays the traction force value while traction is in progress.

[0055] The rope tensioner is used to pull and release the traction rope. When traction is required, the rope tensioner tightly wraps the traction rope, straightening it and increasing the outward traction force. When the rope tensioner releases the traction rope, the outward traction force is removed, allowing the traction rope to relax.

[0056] The rope tightener includes two spaced-apart support bodies 212, a winding drum 226, an anti-reversal member 218, a second pawl 227, a first torsion spring 215 and an operating rod 229. The winding drum 226 is placed between the two support bodies 212. One end of the two support bodies 212 is connected by a first limiting roller 211, and the other end is connected by a second limiting roller 219. The operating rod 229 is rotatably mounted on the support body 212. The winding drum 226 is provided with a ratchet 2262. The second pawl 227 is mounted on the operating rod 229 and is connected to the third torsion spring. 228 is connected and meshed with the ratchet 2262 for transmission connection; the anti-reversal member 218 is provided with a first pawl 2181, which is rotationally connected to the support body 212 and is elastically squeezed by the second torsion spring 225. The first pawl 2181 maintains an engaged link with the ratchet 2262 to prevent the ratchet 2262 from reversing; wherein, the two support bodies 212, the winding drum 226 and the operating rod 229 are connected through the first shaft 213; the first torsion spring 215 is installed on the first shaft 213, and its two torsion rods are elastically connected to the two ends of a support body 212 respectively.

[0057] The connection structure of the two torsion rods of the first torsion spring 215 and the support body: the first torsion rod 2151 is elastically connected to one end of the support body, and the other end of the support body is elastically connected to the second torsion rod 2152.

[0058] The third torsion spring 228 is installed on the operating rod 229 through the third shaft 230. The fifth torsion rod 2281 of the third torsion spring 228 is elastically connected to the operating rod 229. The sixth torsion rod 2282 is elastically connected to the second pawl 227. The sixth torsion rod squeezes the second pawl 227 and places it on the top of the ratchet 2262. When the operating rod 229 swings, the operating rod 229 drives the second pawl 227 to move and maintain an engaged transmission connection with the ratchet 2262, so that the second pawl can push the ratchet to rotate.

[0059] It should be noted that when the operating lever is reset, the second pawl is not located in the tooth groove of the ratchet, but is located on the top surface of the ratchet. Therefore, the second pawl does not prevent the ratchet from rotating in the opposite direction.

[0060] like Figure 8 As shown, one structure of the support body includes a first extension end 2121, a second extension end 2123, and a main body 2122. The main body 2122 can be a disc-shaped structure. The diameters of the first extension end 2121 and the second extension end 2123 are both smaller than the diameter of the main body 2122. The first extension end 2121 and the second extension end 2123 extend outward from the main body 2122 and gradually taper. A visual opening 2120 is defined at the connection between the first extension end 2121 and the main body 2122. The visual opening 2120 facilitates inspection of the working conditions of the components within the two support bodies.

[0061] like Figure 6As shown, a structure of a traction force-measuring piece is given, which includes a bracket 220, a pulling spring 221 and a traction plate 222. Slide grooves 2201 are provided on both sides of the bracket 220, and a sealing plate 2202 with a through groove 2203 is provided at one end, which is rotatably connected to the rope tightener; guide sliders 2221 are provided on both sides of one end of the traction plate 222, and are connected to one end of the pulling spring 221, and the other end passes through the through groove 2203, and the guide slider 2221 is inserted into the corresponding slide groove 2201 and extends outward from the side of the corresponding bracket 220; the other end of the pulling spring 221 is connected to the rope tightener; wherein, the traction plate 222 is provided with a force measuring scale 2222.

[0062] The length of the guide slide 221 extending outward relative to the bracket 220 can be 2 to 3 cm. The two guide slides can support the traction plate so that it will not separate from the guide groove when moving on the bracket.

[0063] The force scale 2222 allows the user to quickly determine the applied traction force. The force scale 2222 can range from 10 to 60 kg. The scales available are 10 kg, 20 kg, 30 kg, 40 kg, 50 kg, and 60 kg. The applicable traction force range is 20 to 30 kg. Options include 20, 25, or 30 kg. Of course, this is not a limitation; the appropriate traction force can be selected based on the curvature of the lumbar spine.

[0064] It should be noted that one way to read the force measuring scale on the traction plate is: the traction plate 222 moves out of the bracket 220, and when the traction plate stops moving, the sealing plate 2202 is perpendicular to the traction plate. At this time, the scale on the traction plate corresponding to the sealing plate is the traction tension value.

[0065] The traction plate 222 is provided with a hanging hole 2223 for connecting with a traction rope. In order to make it easier for the traction plate to be connected with the traction rope, a first pull ring 223 is additionally installed. The first pull ring 223 can facilitate the traction plate and the traction rope to be tied together and connected.

[0066] like Figure 4 、 5 As shown, one structure of the operating rod 229 includes two swing rods spliced together, and each swing rod is connected to the support body through a first shaft 213. The swing rod can swing relative to the support body 212 by means of the first shaft 213.

[0067] The swinging rod includes a first rod segment 2291 , a second rod segment 2292 and a third rod segment 2293 . The first rod segment 2291 and the third rod segment 2293 are connected via the second rod segment 2292 . The second rod segment 2292 is tilted.

[0068] When the two third rod segments 2293 are spliced together, the two third rod segments can be riveted together by rivets to achieve a fixed connection between the two third rod segments.

[0069] like Figure 4 、 5 As shown, the clamping fixing member includes a clamping body 201, an adjusting screw 207, a second support plate 206, a first support plate 204, a fifth bolt 205, a second clamping plate 209 and a first clamping plate 208. One end of the clamping body 201 is provided with a downwardly bent first leg 202, and the other end is provided with an inclined second leg 210; the first support plate 204 is installed on the first support leg 202, the second support plate 206 is fixedly connected to the first support plate 204 by the fifth bolt 205, and the adjusting screw 207 is screwed together with the second support plate 206 and then rotatably connected to the first clamping plate 208; the second clamping plate 209 is installed on the second leg 210, wherein the clamping body 201 is rotatably connected to the rope tightener.

[0070] The second clamping plate 209 and the first clamping plate 208 can be arc-shaped plates. A rotation connection between the adjusting screw 207 and the first clamping plate 208 can be: the adjusting screw and the first clamping plate can be connected via a bearing. The adjusting screw can rotate relative to the first clamping plate by means of the bearing.

[0071] In order to facilitate the operation of the adjusting screw 207 , a butterfly handle 203 is installed on the adjusting screw 207 . Turning the butterfly handle 203 can drive the adjusting screw 207 to rotate.

[0072] The working mode of lumbar traction of the present invention is as follows: The user lies prone on the support bed with their head naturally resting on the head breathing hole. The first lumbar traction belt is then secured to the user's chest via the second adjustment strap 11, resting against the user's armpits. The first adjustment strap 10 on the first lumbar traction belt is then tied to the traction bracket. The second lumbar traction belt is secured to the user's waist via the second adjustment strap 11 thereon. Two traction devices 20 are then used to apply traction tension to the user. The traction device displays the tension value while providing the traction tension, and the traction plate 222 on the traction device can be used to quickly obtain the traction tension value provided by the traction device.

[0073] The tractor 20 tightly winds the traction rope, providing outward traction. During operation, the fourth torsion rod 2252 of the second torsion spring 225 compresses the first pawl 2181 to maintain engagement with the ratchet 2262. The anti-reversal member 218 prevents the ratchet 2262 from rotating in the reverse direction, allowing the operating lever 229 to drive the second pawl 227 to push the ratchet 2262 in the forward direction. The rotation of the ratchet 2262 drives the winding drum 226 to rotate, tightly winding the traction rope around the winding drum. When the operating lever is stopped, the anti-reversal member 218 prevents the ratchet 2262 from rotating in the reverse direction.

[0074] Pulling the pull ring 223 drives the pull rope 217, which in turn pulls the anti-reversal member 218 to swing, causing the first pawl 2181 on the anti-reversal member 218 to disengage from the ratchet 2262, thus releasing the blockage preventing the ratchet from rotating in the opposite direction. During the pulling process, the pull spring 221 elastically deforms, generating elastic deformation potential energy. The pull spring pulls the traction plate in the opposite direction to reset itself, which in turn pulls the traction rope 17 outward from the winding drum 226, releasing the pulling action.

[0075] The present invention adopts a prone position when assisting in lumbar traction. When lying prone, the lumbar spine is facing upwards, which makes it easy to observe the changes in the user's lumbar spine and facilitates the cooperation of the traction device to carry out angle adjustment, so as to adjust the lumbar curvature to restore the normal curvature. During actual use, the traction force applied to the user is usually 20 to 30 kilograms, which is adjusted according to different situations. The number of times traction is used usually varies from three to seven times; through the adjustment of the device of the present invention, the discomfort will gradually be alleviated or eliminated, and the curvature of the lumbar spine will slowly return to normal.

[0076] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
