Description

[0001] Apparatus for spine traction and support [0002]

The present invention can support the spinal column of the upper body by pulling tension between the axilla and the pelvis in a direction opposite to each other and alleviate the load applied to the spinal column and the pelvis, thereby alleviating the pain of the poor spinal column and pelvis The present invention relates to a spinal support and traction device that can suppress the incidence of spinal and pelvic disease and maintain the upper body posture properly so that the cardiopulmonary function is maintained smoothly.

BACKGROUND ART [0002] Conventionally, various devices have been proposed as devices for pulling back the waist or pulling the spine to relieve back pain.

Such a device is disclosed in Korean Patent No. 10-1370518, in which both belts are attached to the pelvis and the waist respectively, and are pulled in opposite directions to each other by a pulling device between the two belts, thereby treating the disc or relieving the pain. . In this case, a belt is put on each of the pelvis and the waist and tension is applied between the belts. Therefore, when the belt is loosely worn, the belt and the body are outwardly turned, and when the belt is tightly tightened, the blood circulation is hindered. Moreover, there is a problem that the desired effect can not be achieved by stretching only the skin rather than stretching the spine.

As another device, Korean Patent Registration No. 10-0495750 discloses a spinal assist device for a spinal patient that enables daily living in the case of a patient who has injured the thoracic and lumbar spine, has a disk damage, or is in recovery period after surgery have. This vertebral orthosis is equipped with a compression spring and an air pump to double the working pump to absorb the instantaneous impact as well as the weight of the upper body. This means that the function of the compression pump to lift the upper body is not moving, Direction, that is, the higher the movement is, the more the action is performed, the stronger the action becomes, so that the function can be performed more.

In the case of the spinal orthosis, the compression pole is configured to be straight so as to be insertable into the pump body of the compression pump. When the wearer moves his / her body back and forth and right and left, the compression pole is bent, There is a problem that it is lost. Furthermore, when the wearer moves his body deeply and continuously for a long period of time, the contact between the compression pole and the pump body of the compression pump is broken. When the contact portions between the compression pole and the pump body of the compression pump are broken and separated from each other, the compression pole pierces the side of the wearer, thereby causing a serious safety accident.
