Description

  Supports the three points of the sacroiliac joint and the left and right hip joints, controls the functional chain of the skeleton, and stabilizes the fitting state of the joints appropriately to improve the stability of the entire pelvis, especially when riding in a wheelchair, especially wheelchair competition An attachment device for forming a skeleton position of a trunk from a pelvis suitable for boarding in a car is provided.

  Conventionally, many kinds of pelvic correction wearing devices worn around the waist and hips have been devised. Among them, there has been proposed a pelvic correction belt with improved wearing stability for the purpose of preventing the belt being worn, including a sitting position, (see Patent Document 1).

  In addition, a medical corset with a devised exterior shape designed to reduce the burden on the waist and prevent displacement to the upper part of the body with the lumbar fixation band and pelvic fixation band while reducing the trouble in daily life due to wearing It has been proposed (see Patent Document 2).

On the other hand, when the applicant investigated, wheelchair athletes devised and used commercially available back pain belts for healthy people according to the degree of handicap, or fixed the body to the wheelchair. The current situation is. As a document related to the latter, a support system has been proposed in which a body is fixed by a plurality of belts provided in a wheelchair in order to ensure the stability of the chassis (Patent Document 3).
Japanese Patent No. 3530787 JP 2004-209050 A Abstract of Japanese Patent No. 5564786

  The invention according to Patent Document 1 is a pelvic correction belt that has been devised to ensure a wide area from the waist to the buttocks because the problem of preventing the belt from rising is a solution. In this document, the sacral correction block 26 made of silicon or the like carrying far-infrared radiation ceramics or the like is detachably provided. The block is intended to obtain a far-infrared effect, and the block is pressed. It is not intended to correct the sacrum. In fact, the sacrum forms a sacroiliac joint with the iliac bone, but the joint is also called a fixed joint, and the block alone does not have a correction force due to the general pressing.

In addition, the invention according to Patent Document 2 reduces the load applied to the spine and the lumbar region by tightening the periphery of the lumbar region with a lumbar fixation band to increase intra-abdominal pressure, and fixes the entire pelvis with the pelvis fixation band. An improvement on the “medical” corset. In this document, as a variation, a corset in which a reinforcing plate using a metal such as aluminum is provided on the waist and back is proposed.
However, according to the invention, even if improvement in wearability as a “medical” corset can be expected, the belt-shaped body is simply wound around the waist of the human body to uniformly apply pressure in the trunk axis direction. It is not out of the range of conventional ideas. Therefore, further improvement focusing on the viewpoint of pelvic correction of athletes who require special athletic ability in a sitting position called wheelchair competition has been desired.

  In terms of ensuring the stability of the body in the sitting position of a wheelchair, not only the idea based on the technical idea disclosed in Patent Document 1 and Patent Document 2, but also an idea from a different viewpoint is required. In other words, the skeletal chain of the hip joint and sacroiliac joint is a necessary function for biped walking, but in the sitting position, the part corresponding to the heel during walking, that is, the part that supports weight is the sciatic nodule part. The skeletal chain of the hip and sacroiliac joints exceeding a certain movable angle is a factor that brings about instability of the entire pelvis, and there has been a long-awaited improvement by experts in order to stabilize this effectively.

  Moreover, the invention according to Patent Document 3 aims to ensure the stability of the body in the sitting position within the normal living range. Therefore, when the invention described in this document is applied to, for example, a wheelchair used by a wheelchair basketball player or a wheelchair marathon player, the chassis is fixed to the wheelchair more than necessary, and the performance of necessary operations is hindered. It becomes.

  In view of the above-mentioned prior art and current problems, the present invention does not consider whether or not it is in an original fitting state, but only in a wide range and not simply tightening the waist around a double triple, It came to a conclusion that it was essential to develop a wearing device that would work effectively, taking into account the fitting state of the main joint sites.

  Then, after the sacroiliac joint is guided to the original correct fitting state, the fitting state is stabilized, and the hip joint, which is a ball joint, is applied to the greater trochanter part without dispersing a constant pressing force. Supporting the spinal column while simultaneously securing the stability of both joints, which stabilizes the fitting state, stabilizes the athlete's body in wheelchair competition and limits the body motion required instantaneously It is an object of the present invention to provide a wheelchair pelvis stable wearing tool that is not used.

  In order to solve the above problems, the present invention is configured as follows. That is, the pelvis stable wearing device for a wheelchair according to claim 1 mainly covers the iliac and hip joints from the sacroiliac joint, and is attached to a basic belt having locking means at both ends using an elastic material. It has a pressing pad that comes into contact with the greater trochanter part, a pressing protrusion that comes into contact with the sacroiliac joint part, and is provided with locking means at both ends.

  The wheelchair pelvis stable wearing device according to claim 2 mainly comprises a basic belt that covers the iliac and hip joints from the sacroiliac joint and uses a stretchable material, and has a locking means at both ends, and a part thereof A wearing device comprising an auxiliary band sewn on a basic belt and made of a material having a higher expansion / contraction rate than the basic belt, wherein the basic belt comprises a pressing pad that contacts the greater trochanter part of the femur, and a sacroiliac Each of the auxiliary bands is provided with pressing protrusions that come into contact with the joint parts, and the auxiliary band is sewn at the center part of the basic belt and the center part of the back side surface of the belt, extends in the left-right direction, and is tightened by turning forward from the hip joint. A large trochanteric pressing auxiliary band, and two sacral pressing auxiliary bands that are sewn at one end above the auxiliary band sewing part, extend in the left-right downward direction, rotate forward from the iliac, and tighten. Both child pressing auxiliary bands When, was characterized by having a locking means of the basic belt and the other end of each of the sacrum pressing auxiliary band.

  The wheelchair pelvis stable wearing device according to claim 3 is the configuration according to claim 2, wherein the greater trochanter auxiliary band is disposed at one end from the central portion of the back surface of the basic belt to the greater trochanter portion. Two great trochanter pressing assist bands that are sewn, stretched in the left-right direction, turned forward from the hip joint, and tightened.

The hip joint (12) is a ball joint composed of an acetabulum and a femoral head. The femoral head has a spherical shape larger than a hemisphere, and the acetabulum is deeply formed so as to accommodate the femoral head (FIG. 6).
Therefore, according to the pelvis stable wearing device for wheelchair according to claim 1, the force P1 pressed by the greater trochanter pressing pad directly acts on the greater trochanter portion of the femur without being dispersed, It is possible to appropriately stabilize the fitting state of the hip joint composed of the femoral head (FIG. 9).

On the other hand, the sacrum (10) forms the iliac bone (9) and the sacroiliac joint (11) (FIG. 6). The sacroiliac joint is generally called a fixed joint, but actually moves and performs joint movement. In the sitting position, the sciatic nodule is the part that supports the body weight, so the hip joint that is linked to the joint movement of the sacroiliac joint, and the mutual skeletal chain of the sacroiliac joint that is linked to the joint movement of the hip joint are unstable in the waist. Bring. Thus, appropriately stabilizing the sacroiliac joint is one of the necessary conditions for ensuring the stability of the entire pelvis. Here, “appropriately stabilizing” means that the sacroiliac joint is stabilized after being guided to the original fitting state.
Therefore, according to the pelvis stable wearing device for a wheelchair according to claim 1, an inward force P2 (FIG. 7) and a downward force P2 (FIG. 7) pressed by the sacroiliac joint pressing protrusion. 8, FIG. 10), together with the pressure P3 (FIG. 10) from the abdominal side, directly acts on the region from the upper posterior iliac spine to the lower posterior iliac spine of the left and right sacroiliac joints, After (11) is guided to the original fitting state, it is stabilized. In this respect, even if it is in an inappropriate fitting state, it is greatly different from the prior art which is simply tightened and fixed.

  As described above, when the fitting state of the hip joint and the sacroiliac joint is appropriately stabilized (FIGS. 9 and 10), the functional chain of the sacroiliac joint and the hip joint is effectively controlled, and the stability of the entire pelvis is improved. Let As a result, it is possible to support the vertebral column composed of the cervical vertebrae, the thoracic vertebrae, and the lumbar vertebrae based on the sacrum, and to form the trunk skeleton position from the pelvis suitable for riding in a wheelchair competition.

  According to the pelvis stable wearing device for a wheelchair according to claim 2, the greater trochanter pressing assist band applies the pressing force to the greater trochanter by the greater trochanter pressing pad, and the sacral pressing assist band includes the sacroiliac joint. The pressing force applied to the sacroiliac joint by the pressing protrusions is further increased, and the stability of the pelvis as a whole can be further improved.

  According to the pelvis stable wearing device for a wheelchair according to claim 3, since the fulcrum of the left and right large trochanter pressing auxiliary band is located on the left and right body side portions when worn, that is, in the vicinity of the greater trochanter, the auxiliary band The pressing force at the time of tightening acts more directly on the left and right greater trochanter part. With such a configuration, it is possible to further improve the stability of the entire pelvis described above.
