Chair for relieving lumbago symptoms of lumbar disc herniation patient

Abstract

The invention relates to the technical field of seats, in particular to a chair for relieving lumbago symptoms of lumbar disc herniation patient. The chair comprises a backrest used for supporting thesternum and the chest wall and consists of a back cushion, a third pin column, a backrest bracket and a sleeve; wherein a base and a cushion are used for supporting the buttocks and the thighs, the ends of the base and the thighs are far away from the backrest bracket, an acute included angle is formed between the base and the horizontal plane, and the angle of the base and the cushion is adjustable. The base is supported by a base support rod and a base bracket fixed on a base tray parallel to the horizontal plane. The chair effectively supports the sternum and the front chest wall, so thatthe pressure load of the body above the lumbar intervertebral disc borne by the lumbar intervertebral disc can be reduced; the whole lumbar intervertebral disc can bear longitudinal pressure uniformlyafter the lumbar spine naturally straightens, the load on the lumbar intervertebral disc caused by muscle contraction to maintain the sitting and forward bending posture can be eliminated, the pressure load borne by lumbar intervertebral disc process is relieved from multiple angles, and the lumbago symptom of a patient suffering from lumbar intervertebral disc protrusion is relieved.

Description

technical field [0001] The invention relates to the technical field of seats, in particular to a seat for relieving low back pain symptoms of patients with lumbar disc herniation. Background technique [0002] The intervertebral disc is composed of the upper and lower cartilage plates, the central nucleus pulposus and the surrounding fibrous ring. The nucleus pulposus is a jelly-like collagen substance, which is elastic and expansive, and can be deformed under pressure. The fibrous annulus is thicker in front and on both sides, so it has a stronger ability to withstand longitudinal pressure; the posterolateral side is weak, and the nucleus pulposus tends to protrude posterolaterally when it is compressed. [0003] In the standing position, the nucleus pulposus bears the weight of the trunk above the level of the intervertebral disc, and the entire intervertebral disc bears the longitudinal pressure evenly. [0004] Through the lumbar intervertebral disc manometry, it was f...

AI Technical Summary

Problems solved by technology

[0008] The technical problem to be solved by the present invention is to design a seat that can reduce the pressure load on the nucleus pulposus of the lumbar intervertebral disc from multiple angles as much as possible, and alleviate the symptoms of low back pain in patients with lumbar disc herniation: by reducing the nucleus pulposus of the intervertebral disc being squeezed forward to reduce the direction of the nucleus pulposus The posterior deformation is prominent, reducing the pressure load on the body above the intervertebral disc borne by the lumbar intervertebral disc, and eliminating the pressure load on the lumbar intervertebral disc caused by muscle contraction to maintain the sitting and forward bending posture
