Description

This belt corrects the intracapsular movement of the sacroiliac joint and promotes normal intracapsular movement. Specifically, by applying a certain pressing force to the area between the upper posterior iliac spine and the lower posterior iliac spine, it acts directly on the sacroiliac joint, resulting in a normal fitting state in the sacroiliac joint and the pelvis the stabilize the sacroiliac joints as a base of the spine by inducing the normal position, there is provided a belts to form an ideal S-shaped curvature in the spine.

In addition, the bell that presses in an effective direction in consideration of the angle of the joint surface at the sacroiliac joint, in addition to always exerting a pressing force in synchronism with the movement of the sacroiliac joint while wearing, without obstructing the movement it is to provide a door.

Conventionally, many kinds of pelvic correction tools worn around the waist and hips have been devised. Among them, a belt-like elastic belt with a small expansion / contraction rate is attached to the protrusion of the upper part of the pelvis of the pelvis with a locking device such as a buckle, and the pelvis is restored to its normal state by tightening the pelvis, and the state is maintained. On the other hand, there has been proposed an adjuster that prevents the pelvic distortion from returning to the original distorted state by forging the muscles around the pelvis with good balance (see Patent Document 1).
JP 2005-304645 A

  The invention according to Patent Document 1 aims to attach a belt-like elastic belt to the upper part of the iliac bone of the pelvis with a locking tool such as a buckle, uniformly tighten the pelvis with the belt-like elastic belt, and return the pelvis to a normal position. And The user then trains the muscles that support the pelvis while maintaining its normal state, that is, the abdominal muscles, back muscles, quadriceps, hamstring muscles, gluteal muscles, adductor muscles, etc. It is advocated not to return to a distorted state.

The sacrum that makes up the pelvis and the left and right iliac bones are connected by a sacroiliac joint, but this sacroiliac joint is called an immobile joint in anatomy, and is actually in the joint capsule in units of several millimeters. It has been confirmed to exercise. And although it is protected by a strong ligament, the joint surface is easy to shift due to a flat ear surface.
Generally, 60% of the weight of the human body is considered to be the weight of the upper body, and the weight of the upper body is converted into a lateral force in the pelvis and is constantly subjected to a force that is spread outward. The force antagonizing this force is the ligament and muscle force around the pelvis, and the sacroiliac movement is composed of a balance of these two forces. However, if the balance of these two forces is lost due to lack of exercise, lifestyle, aging, or other factors, a fitting error occurs in the sacroiliac joint surface, causing three-dimensional displacement of the pelvis, that is, pelvic distortion. This gives an abnormal load on the muscles and ligament tissue around the pelvis, causing pain and numbness, as well as forming an inappropriate S-shaped curvature of the spine, so when correcting the pelvis, A direct and effective action on this sacroiliac joint is desirable.

  However, the invention described in Patent Document 1 is merely to wrap the belt-like elastic belt around the waist of the human body, and does not aim at correcting the displacement of the sacroiliac joint, but applies pressure uniformly in the trunk axis direction. Since there is no out-of-the-box concept, there is room for improvement in terms of direct and effective action on the sacroiliac joint.

  In view of the above problems, the present invention aims to correct the displacement of the sacroiliac joint rather than simply tightening the waist circumference uniformly, and obtains a direct and effective action on the sacroiliac joint It is an object of the present invention to provide a sacroiliac intra-capsular movement correction belt comprising:

In order to solve the above problems, the present invention is configured as follows. That is, the sacroiliac joint movement correction belt according to claim 1 is a belt-shaped belt made of a non-stretchable material or a non-stretchable material at both ends of a belt-like body α made of a stretchable material or a stretched material. The front anterior iliac spine of the iliac that extends either the body β or the belt-like body β, the stretchable material having a lower stretch rate than the belt-like body α, or the belt-like body β subjected to the same stretch processing is formed. The belt is an adjustable belt that is wound and tightened around the body side of the substantially lower position, and at the time of wrapping, the belt is substantially in contact with the region portion between the upper posterior iliac spine and the lower posterior iliac spine. Rutotomoni provided a pair of right and left pressing members which are spaced from one another on the back surface of the strip alpha, a locking member provided on the belt ends, the pressing member, the pressing direction of the human body in the sagittal plane The surface in contact with the human body is a left and right pressing member so that the angle is within a range of 30 ° to 60 °.
