Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of rehabilitation physiotherapy devices for patients with lumbar disc herniation. BACKGROUND
[0002] The intervertebral disc is composed of upper and lower cartilage plates, a central nucleus pulposus, and a fibrous ring around it. Through lumbar disc pressure measurement, it is found that the nucleus pulposus bears a pressure load of 100% in standing position, 150% in vertical sitting position, and up to 270% in sitting forward bending position (i.e. the usual sitting working posture). SUMMARY
[0003] People want to lean on other objects for rest when standing for a long time, and leaning is to reduce the tension on the waist and back. When working in a sitting position, the tension in the sitting forward bending position is very large. If a forward chest wall is provided for leaning in a forward leaning sitting position, the waist and back are relaxed, achieving the effect of leaning on other objects for rest when standing for a long time, which is beneficial to patients with lumbar disc herniation who sit for a long time.
[0004] The present application is a leaning support device for the front chest wall when working in a forward leaning sitting position, which is composed of a vacuum suction cup that can be fixed on the desktop, a support rod with adjustable length, a hinge structure fixed on the suction cup and linked with the support rod, a shallow arc-shaped front chest wall support frame fixed on the other end of the support rod, a device for adjusting the angle between the support rod and the horizontal plane linked between the suction cup and the support rod, etc.
[0005] The aforementioned shallow arc-shaped front chest wall support frame can be adjusted to a rectangular sternum support frame for female users.
[0006] The aforementioned device for adjusting the angle between the support rod and the horizontal plane linked between the suction cup and the support rod can be a rod-shaped object with adjustable length and a clamping groove at the lower part of the support rod.
[0007] The present application is creative: for patients with lumbar disc herniation, a leaning support is provided for the front chest wall when working in a forward leaning sitting position, the waist and back are relaxed, which is beneficial to patients with lumbar disc herniation who sit for a long time.
