Description

Spinal column load-free auxiliary tool

Technical Field

The application relates to the technical field of rehabilitation assistive devices, in particular to a spinal load-free assistive device.

Background

The spine is a central shaft skeleton of a human body, is a support of the human body, and has the functions of loading, shock absorption, protection, movement and the like, wherein the loading of the spine is the sum of weight, muscle tension and external loading of a certain section or more. The spinal segments in different locations bear different loads. These loads require corresponding joints, ligaments and muscles to maintain. Because the lumbar vertebra is positioned at the low position of the spine, the load is quite large, and the lumbar vertebra is the junction of the movable section and the fixed section of the human body, so the lumbar vertebra has more chances of being damaged and becomes the most frequent part of the lumbago and backache. Low back pain is a group of syndromes with low back pain as the main manifestation. It is widely accepted by the modern medical community that aging of muscles and lack of movement results in weakening of the muscular strength and thus deterioration of the muscular strength supporting the spine, which is the root cause of lumbago. In addition, four physiological curvatures of the neck, chest, waist and sacrum are visible in the normal spine, with the cervical and lumbar curvatures convex forward, the thoracic and sacral curvatures convex rearward, which should be a straight line when viewed from the rear, and the torso bilaterally symmetrical. Teenagers are critical to growth and development, and some teenagers and children have three-dimensional deformities with abnormal sequences in the coronal, sagittal and horizontal positions of the spine, namely scoliosis. The above two groups and other spinal disease groups need to reduce spinal load as much as possible. In addition to self-load, in daily life, people inevitably need to carry some articles with them, namely, external load, whether the load is carried by hands or shoulders and backs, the weight of the articles is transmitted to pelvis through the spine and finally reaches the ground from lower limbs, so that the load of the spine is increased, and the requirement for reducing the load of the spine cannot be realized.

In this embodiment, the front of the sagittal plane of the human body is the abdominal pressure pad 31, and the back is the bionic spine 21 and the partitioned bag 22, so that the intra-abdominal pressure can be increased to generate the longitudinal traction force to reduce the longitudinal load of the spinal column 200 of the human body, but the motion of the spinal column 200 of the human body can not be completely fixed, the motion in a certain direction and a certain angle can be allowed, and the comfort can be kept. And the balance weight of the physiological curvature guiding subarea packet 22 of the bionic spine 21 is attached to the center line of the human body as much as possible, so that the distance from an external load acting point to the human body is reduced to the maximum extent, the force arm is reduced, and the moment is reduced.

As shown in fig. 6, the coronal plane of the human body is combined by the use of the externally weighted weight and the strap, so that the downward negative gravity F1, the tension F3 of the inward first connecting strap 41 to the shoulder, and the tension F2 of the third connecting strap 43 under the armpit and the pelvic support force F4 act on the human spine 200 to generate the resultant corrective force. Thus, the back side of the horizontal plane of the human body is the resultant force of correction, the side surface is the pulling force F2 of the third connecting belt 43 under the armpit, the center of the human body also has the outward expansion force under the action of abdominal pressure, the comprehensive effect of thoracic anti-rotation is achieved, and the load of the spinal column 200 of the human body is reduced.
