Description

Chiropractic device {SPINE CALIBRATION APPARATUS}

The present invention relates to a chiropractic device.

The spine is the bone that keeps the main skeleton from the person's neck, back, waist, hips and tail. The spine may have seven cervical vertebras (cervical vertebra), 12 thoracic vertebrae (thoracic vertebrae, thoracic vertebra) and 5 lumbar vertebrae (lumbar, lumbarvertebral), and 5 sacrum (sacral, Sacrum), four tailbones (michu,, coccyx) can be added. In addition, the occipital bone is the upper cervical vertebrae and the cervical vertebrae (first cervical vertebrae) and the axial vertebrae (second cervical vertebrae) are involved in the movement of the cervical spine.

Recently, as people spend more time sitting and living, the number of patients whose spinal joints are misaligned due to poor posture is increasing rapidly. In addition, chronic shoulders such as neck, shoulder, waist and knee due to malalignment syndrome The pain is increasing.

In particular, bad posture (see Fig. 1 (2)) compared to normal posture (see Fig. 1 (1)) causes misalignment of the lumbar spine, thoracic vertebrae and cervical spine due to changes in pelvic tilt, resulting in thoracic kyphosis, round shoulders, and head forward position.

Accordingly, various orthodontic instruments have been released for correcting misalignment of vertebral joints due to bad posture. In one example, orthodontic and massage instruments are used to selectively drive a plurality of points of a pad on which a patient rests in a vertical direction, thereby bending an unaligned spine to a normal state.

Medically, correcting the vertebrae after aligning the vertebrae with the normal curve formed in each area of the spine may improve the correction effect. Nevertheless, in the general orthodontic appliance, the upper surface of the pad is flat, and the patient's misaligned vertebrae are seated on a flat pad so that the correction is performed in an uncomfortable state, and thus the correction is not effectively performed. Moreover, this misinvention has the problem of causing misalignment or worsening of the spine.

In addition, patients have different body types, and accordingly, the lengths of the cervical, thoracic and lumbar spine are different. Nevertheless, a general orthodontic appliance does not consider the patient's body shape, and there is a problem in that normal correction is not performed as the correction is performed according to the average body shape.

At least a portion of the lumbar spine may be seated.

Each of the first pad 1, the second pad 2, and the third pad 3 may include a top surface, a bottom surface, and a side surface disposed between the top surface and the bottom surface to connect the top surface and the bottom surface. At least one of the upper surfaces of the first pad 1, the second pad 2, and the third pad 3 may be changed in a vertical phase by the driving module 4. In this case, at least some of the upper surfaces of the first pad 1, the second pad 2, and the third pad 3 may be changed in phase in the vertical direction.

That is, the upper side of the longitudinal section of the first pad 1 may be formed along the first curve 1-1. In addition, the first curve 1-1 of the upper surface of the first pad 1 may be continuously formed along the width direction. The first curve 1-1 of the upper surface of the first pad 1 may correspond to at least a portion of the curve of the cervical spine of the normal spine. Therefore, the cervical spine of the patient seated on the first pad 1 may be aligned with the curve of the cervical spine of the normal spine.

That is, the upper side of the longitudinal section of the third pad 3 may be formed along the third curve 3-1. In addition, the third curve 3-1 of the upper surface of the third pad 3 may be continuously formed along the width direction. The third curve 3-1 of the upper surface of the third pad 3 may correspond to at least a portion of the curve of the lumbar vertebra of the normal spine. Therefore, the lumbar spine of the patient seated on the third pad 3 can be aligned with the curve of the lumbar spine of the normal spine.

The driving module 4 may change a vertical phase of at least a portion of the upper surface of the first pad 1. As a result, the curvature and / or flatness of the first curve 1-1 on the upper surface of the first pad 1 may be changed. The driving module 4 may change the vertical phase of at least a portion of the upper surface of the second pad 2.

The driving module 4 may change the vertical phase of at least a portion of the upper surface of the third pad 3. As a result, the curvature and / or flatness of the third curve 3-1 on the upper surface of the third pad 3 may be changed. In this case, the driving module 4 may independently drive the top surfaces of the first pad 1, the second pad 2, and the third pad 3.

Various drive machines can be used for the drive module 4. For example, the driving module 4 injects or discharges fluid (air, carbon dioxide, water, oil, etc.) into the internal spaces of the first pad 1, the second pad 2, and the third pad 3. It may be a pump that creates a positive or negative pressure. To this end, the drive module 4 may be a hydraulic or pneumatic or electronically controlled cylinder.

In the first embodiment, the first pad 1, the second pad 2 and the third pad 3 withstand the weight of the patient so that the patient's spine is aligned with the normal spine. Therefore, the first pad 1, the second pad 2 and the third pad 3 should secure a certain level or more of rigidity. As a result, in order to change the vertical phase of the upper surface of the 1st pad 1, the 2nd pad 2, and the 3rd pad 3, the drive module 4 which ensures the drive force more than a predetermined level is needed.

As described above, a cylinder is preferably used for the drive module 4 of the first embodiment.

On the other hand, it is effective to start the correction in the lumbar spine, which is located at the lower part of the spine and supports a lot of weight load due to gravity, and then sequentially corrects the thoracic and cervical vertebrae. As a result, as shown in FIG. 3, it is preferable to repeat the driving of the third cylinder 4-3, the second cylinder 4-2, and the first cylinder 4-1 sequentially. That is, after changing the 3rd curve 3-1 of the upper surface of the 3rd pad 3 convexly upward, it returns to the original position, and makes the 2nd curve 2-1 of the upper surface of the 2nd pad 2 upward. After the convex change, the original position is changed, and the first curve 1-1 of the upper surface of the first pad 1 is changed to the upper side, and then the original position may be repeated.

As described above, in the first embodiment, only the first pad 1 may exist or only the first pad 1 and the second pad 2 may exist. When only the first pad 1 is present, the first curve 1-1 of the upper surface of the first pad 1 may correspond to a curve of at least a portion of the cervical spine, the thoracic spine, and the lumbar spine of the normal spine. When only the first pad 1 and the second pad 2 are present, the first curve 1-1 of the upper surface of the first pad 1 may correspond to at least some curves of the cervical spine of the normal spine and The second curve 2-1 of the upper surface of the second pad 2 may correspond to a curve of at least a portion of the thoracic vertebra of the normal spine. In contrast, the first curve 1-1 of the upper surface of the first pad 1 may correspond to a curve of at least a portion of the thoracic vertebrae of the normal vertebrae, and the second curve 2 of the upper surface of the second pad 2 may have different shapes. -1) may correspond to a curve of at least a portion of the lumbar spine of the normal spine.
