Description

Technical Field

[0001] The utility model belongs to the technical field of lumbar traction devices, in particular to a portable self-service lumbar traction device. Background Art

[0002] The treatment methods for lumbar spondylosis are divided into two types: non-surgical treatment and surgical treatment. Traction is the main means of relieving symptoms of cervical spondylosis in non-surgical treatment. Effective traction can relieve neck muscle spasms, relieve pain symptoms, enlarge intervertebral spaces and intervertebral foramina, help stabilize the protruding nucleus pulposus and annulus fibrosus tissue, relieve and relieve nerve root compression and irritation, promote the absorption of nerve root edema, relieve the compression of the vertebra on the vertebral artery, promote blood circulation, help local congestion, swelling and hyperplasia to subside, loosen adhesions of the joint capsule, improve and restore the uncovertebral joint, adjust small joint dislocations and vertebral slippage, adjust and restore the damaged internal and external balance of the cervical spine, and restore the normal function of the cervical spine. Lumbar traction devices are designed based on this principle and are convenient for patients to use at home for the treatment of lumbar spondylosis. Most existing lumbar traction devices are frame structures with a fixed height design, which makes it difficult to adjust the height of the lumbar support to meet different needs.

[0003] Publication number CN217723838U describes a lumbar traction device for treating traditional Chinese medicine bone injuries. By providing a first threaded rod and a second threaded rod, the device achieves optimal traction force, enhancing the therapeutic effect. Furthermore, the threaded rods' ability to move upward and downward during force application and reduction allows for uniform, impact-free movement, protecting the patient's lumbar spine and providing increased safety. Furthermore, the device includes an ice pack, cushioning pad, and traditional Chinese medicine bag, alleviating back and waist pain and effectively protecting and treating lumbar injuries. However, the device still lacks the ability to adjust the height of the lumbar support. Utility Model Content

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] Most of the existing lumbar traction devices are in a frame structure. For patients with different body types and diseases, the required height for supporting the waist is different. Since the existing lumbar traction devices are only fixed protrusions, their height and curvature cannot be adjusted. In view of this, a lumbar traction device with another structure is designed, and the specific structure is as follows.

[0027] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0028] Unless otherwise defined, the directions such as up, down, left, right, front, back, inside and outside involved in this article are based on the up, down, left, right, front, back, inside and outside directions in the figures shown in this utility model, and are hereby explained together.

[0029] Please refer to Figures 1 to 5 , the portable self-service lumbar traction device includes a bottom plate 1, a top arc cover 2 and two side arc plates 3. The top arc cover 2 is located at the center of the top of the bottom plate 1, and the bottom plate 1 is fixed to an external bed body or installation position by means such as bolts.

[0030] Please refer to Figures 1 to 5 , in order to achieve height adjustment, a structure for lifting the top arc cover 2 needs to be used. The lifting structure can be an electric device such as a hydraulic rod or a telescopic rod. Using an electric device can indeed play a role in lifting. However, since the telescopic movement of an electric device such as a hydraulic rod or a telescopic rod requires a certain amount of telescopic space margin, for example, if it is a hydraulic rod, enough space must be left at the bottom to store the length of the fixed part of the hydraulic rod, which leads to a waste of space and is likely to increase the volume of the device. For this point, another lifting structure is designed as follows;

[0031] Two extension plates 14 are fixed to the top of the bottom plate 1. A double lead screw 5 is rotatably arranged between the two extension plates 14 through bearings. Threads with opposite helical directions are provided at both ends of the double lead screw 5. Nut seats 6 are sleeved on both outer ends of the double lead screw 5. The bottom of the nut seat 6 is designed to be in contact with the top of the bottom plate 1. A traction rod 8 is arranged between the top of each of the two nut seats 6 and the top arc cover 2. The two traction rods 8 and the nut seats 6 are designed to be symmetric about the center of the top arc cover 2. A rotary motor 7 is installed on one side of the extension plate 14. The driving end of the rotary motor 7 is connected to the end of the double lead screw 5 through a coupling;

[0032] Due to the design of the nut seats 6 and the traction rods 8 at both ends of the double lead screw 5, the distance between the two nut seats 6, the length of the two traction rods 8 themselves, and the distance between the two traction rods 8 form an isosceles trapezoidal force structure, and the two traction rods 8 are the isosceles sides. Due to the symmetric distribution, when the nut seats 6 move synchronously in opposite directions, a regular movement will further occur, enabling the top arc cover 2 to be lifted and lowered stably.

[0033] Please refer to Figures 1 to 5 , in order to achieve the arc adjustment on both sides, inner grooves are provided on both sides of the top arc cover 2. A plurality of laminated plates 4 are arranged between the top arc cover 2 and the side arc plates 3. The lowermost laminated plates 4 at both ends are fixedly connected to the corresponding side arc plates 3. The plurality of laminated plates 4 are designed to be close to each other. The laminated plates 4 located above are adapted to the inner grooves. At least two strands of string 10 are strung in the plurality of laminated plates 4 on the same side;

[0034] A fixed plate 9 is fixed to the side of the topmost laminated plate 4 and the connecting rope 10. There is a through hole at the bottom of the top arc cover 2. Two side plates 11 are connected to both sides of the bottom of the top arc cover 2. A winding roller 12 is rotatably connected between the two side plates 11. A winding motor 13 is installed on one side of the side plate 11. The driving end of the winding motor 13 penetrates through the side plate 11 and is connected to the end of the winding roller 12. The outer circumference of the winding roller 12 and one end of the connecting rope 10 are designed for winding.

[0035] Two chutes 15 are opened at the top of the bottom plate 1. A sliding part 16 is limited and slid inside the chute 15. The sliding part 16 is fixed to the bottom of the side arc plate 3. A plurality of threaded holes are opened at the inner bottom of the chute 15. A fixing pin 17 is arranged on the sliding part 16. The fixing pin 17 passes through the corresponding threaded hole for fixation.

[0036] In order to improve the aesthetics and safety, a covering cotton layer 18 with elasticity is adhesively fixed to the outer periphery of the device.

[0037] The above connection methods can adopt existing methods such as bonding, welding, bolt connection, etc., subject to actual needs.

[0038] The above components and electrical equipment are all existing technologies or technologies that can be realized currently. Their working principles, sizes and models have nothing to do with the functions of this application, so no more descriptions are made, and they are all controlled by a remote control switch.

[0039] Working Principle

[0040] When the portable self-service lumbar traction device is needed, fix the bottom plate 1 to the bed body or others. Slide the side arc plate 3 to move the sliding part 16 along the chute 15 to the required position, and then use the fixing pin 17 to fix the sliding part 16.

[0041] While pulling the side arc plate 3, start the winding motor 13 to drive the winding roller 12 to rotate, wind and unwind the connecting rope 10, so that the laminated plate 4 is drawn out or pulled into the inner groove of the top arc cover 2. Due to the close design of the multiple laminated plates 4, it can provide a certain support.

[0042] When the height needs to be adjusted, start the rotating motor 7 to drive the double lead screw 5 to rotate. Due to the thread design of the double leads at both ends, the two nut seats 6 can move synchronously, so that the traction rod 8 moves synchronously, and further the top arc cover 2 is lifted or lowered, thereby adjusting the height, and thus the function of adapting to different patients can be realized.

[0043] It should be noted that, in this text, relational terms such as "one" and "two" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variation thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising one..." does not exclude the existence of additional identical elements in the process, method, article or device comprising said element.

[0044] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
