Gradient individually-adjustable three-dimensional air cushion structure for sectional backbone drawing bed

Abstract

The invention relates to a gradient individually-adjustable three-dimensional air cushion structure for a sectional backbone drawing bed. The three-dimensional air cushion structure comprises an air cushion arranged on the body of the sectional backbone drawing bed, and a plurality of column structures. A plurality of latticed meshes are uniformly distributed in the air cushion. The upper ends of the plurality of column structures are fixedly connected to the plurality of meshes, and the lower ends of the plurality of column structures are mounted on the bed body respectively. The plurality of column structures are driven by a power medium source to stretch and retract independently in the vertical direction. When the plurality of column structures stretch and retract independently respectively, the corresponding parts of the air cushion are driven to rise and fall to adjust the gradient of the air cushion and the bracketing forces for different parts of a human body. The three-dimensional air cushion structure of the invention is applied to the sectional backbone drawing bed; in the treatment process of drawing the backbone of a human body, the stability, anti-deformation capability and use comfort of the air cushion may be improved, and the gradient of each part of the air cushion may be individually adjusted according to different parts of a human body, so that different parts of the human body can be effectively supported.

Description

technical field [0001] The invention relates to the technical field of air cushions, in particular to a three-dimensional air cushion structure for a segmented spinal stretching bed, which can be individually adjusted in curvature. Background technique [0002] In recent years, a large number of studies have proved that the degree of relaxation of the patient's muscles during spinal traction or spinal decompression has a significant impact on the treatment of spinal diseases, and because the lumbar spine is curved, whether there is support during treatment will affect the curvature of the spine and affect The location of the lesion in the spine may cause injury. During some treatments, the doctor will put a pillow on the patient's waist, but the height and size cannot be adjusted. The lumbar curve of each patient is different, so it cannot be different from person to person. [0003] The traditional spinal stretching bed used for the treatment of spinal diseases is generall...

[0002] In recent years, a large number of studies have proved that the degree of relaxation of the patient's muscles during spinal traction or spinal decompression has a significant impact on the treatment of spinal diseases, and because the lumbar spine is curved, whether there is support during treatment will affect the curvature of the spine and affect Lesion spine localized or prone to injury

During some treatments, the doctor will place a pillow on the patient's waist, but the height and size cannot be adjusted. The lumbar curve of each patient is different, so it cannot be different from person to person.

[0003] The traditional spinal stretching bed used for the treatment of spinal diseases is generally a rigid structure, which mainly pulls the spine through pulling force. The upper traction frame and the foot fixing frame, the two ends of the bed body are provided with movable bed boards, the head traction frame is arranged on the movable bed board, the foot fixing frame is arranged on the movable bed board, the bed body There is a traction frame on one side; although the corrective force distribution of the spinal traction bed is reasonable, it has a good corrective effect on the spine, and the two-way traction and stretching can avoid fatigue caused to a certain position of the spine, but this rigid structure The method of correcting and pulling the human spine cannot stretch every bone in the human spine, and the therapeutic effect on spinal diseases is not obvious; at the same time, during the treatment process, the human body does not feel comfortable in contact with the rigid structure , even pain

In view of this problem, at present, there is a waist pressing traction bed with the patent number of ZL200720102239.5 on the market, which has a bed board, a bed frame at its bottom and a traction mechanism, and an air cushion is placed at the waist position in the middle of the bed board, which can be inflated Adjust to different heights, cushion the back, and relax the muscles of the lower back; however, although it can solve the technical problem of the soft contact between the human body and the air cushion, the air cushion may be displaced or deformed with inflation and deflation during repeated use. And it is easy to make the air cushion fold when it shrinks, causing uneven inflation or gas flow after inflation is completed, causing discomfort to the patient, and because of the high fluidity of the gas, when the gravity in one place is greater, the gas will be squeezed to other places, such as , because the air cushion spreads all over the middle of the bed body, the waist of the human body mainly focuses on the middle of the air cushion, and more gas will be lost to the sides, which cannot concentrate on the waist of the human body. The supporting force cannot be controlled and adjusted
