Lumbar supine hyperflexion device

Abstract

The invention provides a lumbar vertebra prone hyperflexion instrument, and belongs to the field of a medical appliance. The lumbar vertebra prone hyperflexion instrument comprises a plurality of cushion units, an air compressor, a plurality of electric control valves and a controller, wherein each cushion unit comprises an accommodating base and a regulating support block; an accommodating cavity with an opening formed in the top end is arranged in the accommodating base; the regulating support block is fixed in the accommodating cavity; the regulating support block and the accommodating cavity form a sealing cavity; the air compressor communicates with the sealing cavities of the cushion units through a plurality of electric control valves and an air conveying pipeline; the controller is in control connection with the air compressor and the plurality of electric control valves; one connecting part is arranged at each of the two opposite sides of the accommodating base; and the adjacent cushion units are detachably connected by two connecting parts. Compressed gas generated by the air compressor is conveyed to the sealing cavity of each cushion unit through the electric control valves and the air conveying pipe; the volume of the air entering the sealing cavities is controlled by controlling the opening and closing time of the electric control valves; the use height of each cushion unit is further regulated; and the radian of the human body support surface can be freely regulated.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a lumbar prone over-flexion device. Background technique [0002] Lumbar disease is one of the common orthopedic diseases. With the development of the economy and the improvement of people's living standards, the incidence of the disease is gradually increasing. [0003] Common lumbar spine diseases mainly include the following: [0004] Spinal degeneration: hypertrophic spondylitis, lumbar disc degeneration, lumbar instability and degenerative spondylolisthesis, lumbar spinal stenosis, hypertrophy of ligamentum flavum, calcification of posterior longitudinal ligament, etc.; [0005] Lumbar spinal stenosis: a clinical syndrome caused by bony or fibrous structural changes in the lumbar spinal canal due to some reasons, resulting in narrowing of one or more segments of the lumen and compression of the cauda equina nerve. [0006] Spinal injuries: spinal fractures, acute lumbar spra...

AI Technical Summary

Problems solved by technology

[0010] However, the above-mentioned lumbar prone over-bending apparatus is not flexible enough in height and radian adjustment, and can only be adjusted in a small range.

Moreover, the top surface of the inflatable cushion is a flexible structure with poor support performance; after the air pressure increases, the top surface has stronger support, but at this time, the central part of the inflatable cushion protrudes higher, and the contact area with the human body become smaller, resulting in uncomfortable contact

In addition, its length and width are difficult to adjust, which cannot meet the needs of patients with different body shapes
