[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a back pain band used for prevention and treatment of back pain.

[0002]

[Prior Art]

 There are several methods for treating low back pain, one of which is to attach a back pain band to the lower back. Back pain can be caused by a variety of causes, the greatest cause of which is the misalignment between the lumbar and sacral vertebrae. In order to prevent this deviation and to restore it, the lumbago band must have the following functions.

By uniformly pressing the entire lumbar region and making the muscles tense, the burden on the lumbar and sacral vertebrae is reduced. By supporting the stay on the spine, the dorsiflexion of the lumbar and sacral vertebrae is supported from the back. The pressure in the lower abdomen is applied to increase the pressure in the abdominal cavity and push back the displaced lumbar spine. Stabilize the sacrum by tightening the pelvis. Keeping the affected area warm improves blood circulation and reduces pain.

The conventional lumbago band is used for prevention or treatment by a resting patient or an outpatient or an inpatient, but it is a severe one for enhancing the effect by limiting the movement of the lower back as much as possible. When this type of low back pain belt is worn, the movement of the lower back and abdominal breathing are restricted, which makes it uncomfortable to wear for a long period of time, and continuing to wear it even after returning to society further limits daily activities. Also, when worn by athletes for rehabilitation, they could not bend forward and could not train their abdominal muscles, which was not desirable.

[0005]

[Problems to be solved by the device]

 The object of the present invention is a back pain band suitable for use in low back pain patients for rehabilitation or rehabilitation training, or a back pain band suitable for athletes for preventive or rehabilitation training, with free abdominal breathing and The object is to provide a device capable of flexing, limiting dorsiflexion, stabilizing the ilium and pelvis, and applying abdominal pressure.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, in the present invention, a main body belt formed of an abdominal part made of a stretchable material and a back part made of a non-stretchable material, and a central upper direction of the back part of the main body belt. A stretchable first auxiliary belt that further protrudes in a V-shape to the left and right and the tip reaches the abdominal position, and a second auxiliary belt that protrudes left and right from the lower center of the back position of the main body belt and can tighten the lower part of the iliac bone. The width of the abdominal part of the body belt is made narrower than the width of the dorsal part.

The elastic material for the abdominal part of the main body belt is flexible and has elasticity, has little fatigue even after long-term use, has breathability, hygroscopicity and elasticity, and has a modulus of 20. A value of 0.8 kg / inch or more and 2.0 kg / inch or less at the time of% elongation is suitable, and preferably 1.0 kg / inch to 1.5 kg / inch. The left and right sides are preferably overlapped with each other from the iliac to the abdomen, and the width is 20 cm or less, preferably gradually narrowed from the left and right iliacs to the center of the abdomen, and the narrowest center of the abdomen is 8 cm. The front and back are suitable.

As the non-stretchable material for the back part of the main body belt, it is flexible and has elasticity, has little fatigue even after long-term use, is breathable, absorbs moisture, and is non-stretchable. Is preferably a length capable of covering the dorsal side between the left and right iliac bones, and the width is 20 cm or more, preferably about 25 cm.

As the first auxiliary belt, a rubber woven tape having a width of 3 cm to 15 cm, a relatively thin thickness, a high back stretch, and a small settling is suitable. It is desirable that the length should reach the left and right sides of the front of the abdomen when extending approximately 15% through the left and right flanks from the center of the back.

As the second auxiliary belt, a belt having a width of 3 cm or more and less sagging is preferable, and one of the belts extending from the center of the back position is provided with a foot length adjustable ring and a ring through which the other belt can pass. A hook-and-loop fastener is provided at the tip of the other belt, and a hook-and-loop fastener is provided at an appropriate position of this belt, which can be joined to the hook-and-loop fastener at the tip after folding the belt through the ring provided on the belt. It is desirable that the length extends from the center of the dorsal part to the left and right, and that the front of the abdomen can be connected to each other. Further, inserting a high modulus expansion belt into a part of the second auxiliary belt is effective in preventing the shift and maintaining an appropriate fixing force.

[0011]

[Action]

 In the present invention, since the abdomen of the body belt is made of a stretchable material and has a narrow width, the forward bending movement can be easily performed, and abdominal breathing is also possible. Since the part is made of non-stretchable material and has a large width, excessive movement for dorsiflexion is prevented.

[0012]

【Example】

 Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a front view of an example of a back pain band according to the present invention. The body belt 1 is composed of abdominal portions 2 and 3 located at both ends of the body belt 1 that come to the abdomen when worn on the lumbar region, and a dorsal portion 4 that is located between them and comes to the dorsal region when worn on the lumbar region. There is. The dorsal portion 4 has a large width so that it can cover a wide area on the back surface of the waist. The widths of the abdominal portions 2 and 3 following the left and right of the back portion 4 are selected to be smaller than the width of the back portion 4, and gradually decrease toward the tip, and the maximum width b of the back portion 4 is, for example, 25 cm. In this case, the width a _{1 at} the connecting portion with the back position 4 is, for example, 15 cm, and the width a _{2 at} the tip is, for example, 9 cm.

A hook-and-loop fastener 5 is provided at the end of one abdominal position 3 so that it can be engaged with the other abdominal position 2 by overlapping. The two V-shaped first auxiliary belts 6 and 7 having the V-shaped open ends 8 and 9 are fixed to the left and right of the upper position substantially in the center of the back position 4, and the V-shaped is sharpened. One is directed to the abdominal portions 2, 3 at both ends, and the sharp ends 10, 11 are provided with hook-and-loop fasteners 12, 13, respectively. Second auxiliary belts 14 and 15 are fixed at one ends 16 and 17 to the left and right of a lower position of the center of the back portion 4, that is, below the first auxiliary belts 6 and 7, and one of the second auxiliary belts is fixed. 14 is provided with a length adjusting foot 18 and a ring 19 at the end, and the other second auxiliary belt 15 is provided with a surface fastener 20 at the end and a surface fastener 21 paired with the surface fastener 20 in the middle. Has been.

The stays 22 and 23 are covered and held by the stay covers 24 and 25, which are sewn around the periphery except the upper portion, on the left and right of the center of the back portion 4.

The abdominal portion of the main body belt is made of a material having high elasticity, shape retention, and breathability, and having a looped raised surface on which the surface fastener is attached, for example, an elastic nylon pile / polyurethane nonwoven fabric. / Three-layer stretch fabric of cotton pile, three-layer laminate of stretch nylon pile / neoprene foam / stretch polyester.

The dorsal part of the body belt is made of a material having high elasticity, breathability, and shape retention, for example, French pile / nonwoven polyester / cotton pile, nylon pile / compressed urethane / polyester material, etc. Be done.

The first auxiliary belt is made of a material having strong stretchability, particularly a stretch force stronger than that of the back portion of the main body belt. For example, a flat rubber belt having a width of 5 cm to 8 cm is suitable. This is because if the width is narrower than 5 cm, it will bite into the body and cause pain, and if it is too wide, it will be wider than the abdominal position of the body belt, and as a result, the surface fastener will protrude beyond the abdominal position. .. Further, the modulus of 10 to 50% of the total of the two belts of the first auxiliary belt is 1.8 to 4.0 kg, preferably the modulus of 10 to 30% at 1.8 to 3.0 kg. Preferably. This is because if the elongation is too small, it will not follow the changes in the waist circumference, and if it is too large, the modulus will not increase rapidly when a large load is applied, and the fixing force will be weak. If the modulus value is out of this range, there is a problem that the fixing force is insufficient and the strength of the elderly cannot be sufficiently extended.

The second auxiliary belt is made of a non-stretchable or slightly stretchable material and is flexible enough to fit the body, and is preferably a thin nylon belt. The width is preferably 3 to 10 cm, particularly preferably 5 to 7 cm. This is because if it is narrower than 3 cm, it may bite into the body and cause pain, and if it is wider than 10 cm, it is difficult to tighten only under the iliac bone.

As shown in FIGS. 2 a and 2 b, the back pain band according to the present invention is located inside the back part 4 of the main body belt 1 (on the side where the first auxiliary belts 6, 7 and the second auxiliary belts 14, 15 are provided). Put the other side) on your back and wrap it around your waist so that the second auxiliary belts 14 and 15 are located on the ilium, and stack the other abdomen 3 on the abdomen 2 of the main belt 1. The surface fasteners 5 of the abdominal part 3 are fixed on the abdominal part 2 by aligning and tightening. Then, both ends 10 and 11 of the first auxiliary belts 6 and 7 are stretched and wound around the abdominal portions 2 and 3, and fixed on the abdominal portions 2 and 3 by surface fasteners 12 and 13, respectively. The second auxiliary belts 14 and 15 are wound around the abdominal portions 2 and 3, folded back around the ring 19 of the second auxiliary belt 14 through the end of the second auxiliary belt 15, and the surface fastener 20 is superposed on the surface fastener 21. Fix together. The length of one of the second auxiliary belts 14 is adjusted in advance by using the footjob 18.

As described above, the biggest cause of low back pain is the displacement between the lumbar vertebra and the sacral vertebra, but the main body belt and the first auxiliary belt press the abdomen to increase the abdominal pressure and push the lumbar vertebrae. By returning, the second auxiliary belt stabilizes the sacrum by tightening the pelvis at the iliac position, and the main belt and both auxiliary belts can prevent changes between the lumbar spine and the sacrum. FIGS. 3a and 3b are conceptual views showing the mutual relation of the lumbar bones related to low back pain from the front and side, respectively. Of the five lumbar vertebrae 1 to 5, there are usually five, especially the fifth lumbar vertebrae. The movement between 26 and the sacral 31 is the largest, and problems are likely to occur here. According to the present proposal, the entire lumbar region including the lumbar vertebrae 26 to 30 and the sacral vertebrae 31 is compressed and fixed by the main body belt 1 and a force as indicated by a solid arrow is applied, and the first auxiliary belts 6 and 7 are applied to the abdominal cavity. By increasing the pressure and applying a force to push back the lumbar vertebra that has been displaced forward, the second assist belts 14 and 15 are tightened to the position of the ilium 32 and a force as indicated by a dashed arrow is applied to the iliac 32. Since the compression force is applied to the sacrum 31 located in the lower portion, it has an effect of surely preventing the deviation between the lumbar vertebra and the sacrum and restoring the deviation.

[0022]

[Effect of the device]
