Description

Technical Field

[0001] This utility model relates to the field of lumbar support technology, specifically a portable lumbar support traction device. Background Technology

[0002] Lumbar spondylosis is a common and frequently occurring disease, mainly caused by degenerative changes in the lumbar spine, decreased elasticity and increased fragility of the annulus fibrosus, which ruptures. The nucleus pulposus bulges outward from the ruptured annulus fibrosus, compressing the spinal cord or nerve roots, leading to a series of pathological symptoms such as lumbar facet joint dysfunction, lumbar muscle pain, spasm or tension.

[0003] Lumbar traction is currently a relatively safe and effective method for prevention and treatment. Existing lumbar traction devices mainly include supine traction beds or support frames, lumbar-abdominal traction supports, and upper arm suspension traction devices. The supine traction method involves using a lumbar belt to fix one end to the waist, with the force point located at the upper end of the hip bone. This belt applies downward tension to the body through a connected traction band. The other end uses a chest belt tightly wrapped around the chest, applying upward tension to the body through a connected traction band. To generate sufficient friction to prevent the chest belt from slipping or shifting during support, the binding force must be significant, creating considerable pressure on the chest and rib area. The binding and traction... The discomfort during the process mainly includes squeezing pain and difficulty breathing, and female users find it even more difficult to bear the pressure on their chest. Another type of abdominal traction support uses a waist belt at the lower end, which is tightly wrapped around the upper hip bone, and an abdominal belt at the upper end, which is tightly wrapped around the lower ribs. There is a retractable support device on each side of the body with both belts. By adjusting the length of the support device, a traction force is generated on the lumbar spine. Its main drawback is that the force point of the abdominal belt is located at the lower ribs. When the support force is large, it will generate a large pulling force on the lower ribs, which will cause more serious discomfort.

[0004] Patent CN203861524U, entitled "Lumbar Traction Therapy and Health Care Device," discloses a lumbar support traction therapy and health care device. It includes a left upper support, a left lower support, a left double-ended screw, a left upper support lifting nut, a left lower support lifting nut, a right upper support, a right lower support, a right double-ended screw, a right upper support lifting nut, a right lower support lifting nut, a chest strap, a waist belt, and a lumbar positioning plate. The upper end of the left double-ended screw is screwed with the left upper support lifting nut, and the lower end of the left double-ended screw is screwed with the left lower support lifting nut. The upper support lifting nut is fixedly connected to the upper left support, and the lower left support lifting nut is fixedly connected to the lower left support. The upper end of the right double-ended screw is screwed with the upper right support lifting nut, and the lower end of the right double-ended screw is screwed with the lower right support lifting nut. The upper right support lifting nut and the lower right support lifting nut are fixedly connected. The chest strap is inserted through chest strap adjustment holes one and two, and the waist belt is inserted through waist belt adjustment holes one and two. A lumbar spine positioning plate is installed in the middle of the waist belt for lower lumbar spine positioning and protection. Besides these, many similar devices use axillary supports for support, but the application of support force is always rigid, which makes the support force value uncontrollable and therefore poses a certain risk of strain. Patent number CN219963204U, entitled "A Lumbar Traction Chair," discloses a lumbar traction chair. This invention uses underarm straps to fix the chest, underarm support devices to limit the shoulders, and lower straps to fix the buttocks, placing the body in a traction and stretching state, effectively reducing pressure on the lumbar spine when sitting. However, this technical solution also uses rigid mechanical support, which carries the risk of uncontrollable support force. On the other hand, there are some publicly disclosed multi-functional support chair technologies, including rehabilitation and health care supports or multi-purpose chairs for office and home use. These all claim to be usable as both seats and lumbar support chairs, but the armrest spacing is not adjustable, thus failing to achieve conversion between uses or accommodate people with different chest widths.
