TECHNICAL FIELD OF THE INVENTION
The present invention relates to a waist fixing band wound around the waist from the back of the human body to the waist abdomen, and more particularly, to a waist fixing band including a reinforcing piece having rigidity and moderate flexibility.
[0002]
[Prior art]
When suffering from a lumbar disease such as a lumbar sprain, a lumbar fixing band for fixing the affected lumbar region is often used. The waist fixing band is, for example, a belt belt wound around the trunk axis from the waist back to the waist abdomen of the human body, as shown in Patent Literature 1. The height of the waist was compressed to fix the waist.
[0003]
By the way, this kind of waist fixing band is generally formed of a cloth base material having a part of elasticity for tightening the waist abdomen. However, in the case of a cloth base material, the belt itself easily deforms along the shape of the waist, and the pressure in the abdominal cavity is absorbed by the deformation of the cloth.
[0004]
Therefore, in many of the waist fixing bands of this type, a plurality of reinforcing pieces for posture correction are arranged at predetermined intervals on the back of the waist. As a reinforcing piece, a metal plate such as aluminum or a hard synthetic resin plate is often used, and by this, the reinforcing piece functions as a rib, so that it is possible to receive intra-abdominal pressure on the entire belt surface, A reduction in compression force is prevented.

[Problems to be solved by the invention]
However, the above-mentioned reinforcing pieces still have the following problems to be solved. That is, in the case where the reinforcing piece is made of metal, there is a problem in that since the reinforcing piece is tough, the discomfort given to the patient increases. Further, in order to prevent the reinforcing piece from damaging the base material, it is necessary to carefully remove burrs and the like generated on the end face.
In particular, in the case of iron, there is a possibility that rust or the like may occur.
[0007]
In order to solve the above-mentioned problem, the reinforcing piece may be made of a synthetic resin. According to this, the ability to follow the deformation of the body is improved, but the supporting force (holding force) is reduced this time. Therefore, in order to securely fix the waist, it is necessary to increase the thickness of the plate, and the discomfort to the patient increases.
[0008]
Therefore, the present invention has been made to solve the above-described problem, and an object of the present invention is to provide a waist fixing band having a reinforcing piece that has a better followability to the body and can be securely fixed. Is to provide.
[0009]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a waist fixing comprising a belt-shaped belt wound around the trunk axis from the waist back to the waist abdomen and having a rectangular reinforcing piece on the waist back side. In the belt, the reinforcing piece is made of a synthetic resin, a cross-sectional shape along the trunk axis is formed in an S-shape along the waist back, and the plate thickness is both ends in the trunk axis direction from the center. Characterized by being formed so as to gradually decrease toward.
[0010]
According to this, the reinforcing piece is formed in an S-shape along the waist, and its plate thickness decreases toward both ends, so that the followability to the body is improved toward both ends, and the affected part is removed. The holding force of the holding central portion can be secured.
[0011]
As a more preferred embodiment, it is preferable that a reinforcing rib protrude from the back side of the reinforcing piece. According to this, the reinforcing degree can be effectively increased by providing the reinforcing rib only in the portion where the holding force is required without increasing the overall thickness.
[0012]
It is preferable that the reinforcing rib is provided at a position centered on an inflection point of the reinforcing piece. According to this, by providing the reinforcing rib at the inflection point where the greatest deformation force is applied, the rigidity of the central portion is reliably increased. As the preferable shape of the reinforcing rib, it is most preferable to protrude in a rhombic pyramid shape (pyramid shape), but it may be a hemispherical shape or a linear shape.
[0013]
The above-mentioned reinforcing ribs are preferably arranged in the waist fixing band so as to protrude from the back side, that is, from the back to the outside, and if arranged in reverse, the reinforcing ribs press the human body. Feel uncomfortable. Therefore, it is preferable that a discriminating portion for discriminating upside down and front and back is provided on the reinforcing piece. Examples of the discriminating unit include an arrow display for discriminating up and down and a carved letter for discriminating front and back.
