[Industrial applications]

 The present invention is a lumbar band used for the prevention and treatment of low back pain, especially a lumbar band that is advantageous to be used during sports training and competition for the purpose of early recovery for athletes and for the purpose of preventing recurrence, and further engages in heavy labor. It relates to a waist belt suitable for use by a person to prevent back pain and prevent recurrence.

[0002]

[Prior art]

 There are several methods for preventing and treating low back pain, and one of them is to attach a lumbar band to the lower back pain. The purpose of this lumbar band is to correct and prevent lumbar misalignment to support the lumbar spine in the correct position and to reduce the pressure load on the intervertebral disc. Therefore, the waist band is required to have the following functions. (1) The entire lumbar region is pressed evenly to tense the muscles of the lumbar region, such as the back muscles, rectus abdominis muscles, and external oblique muscles, resulting in a reduction of the weight load on the lumbar spine. (2) The lower abdomen is pressed to increase the abdominal pressure, and as a result, the anterior displacement of the lumbar spine is prevented or corrected. (3) A supporting stay is closely attached to the vicinity of the spine to fix the lumbar spine, and as a result, the lumbar spine is prevented from bending and is held or corrected in the correct position. (4) Tighten the pelvis to stabilize it and, as a result, stabilize the sacrum from the lower lumbar spine. (5) Insulate the lumbar region to prevent a decrease in body temperature, improve blood circulation as a result, and activate various organ activities. Conventionally existing waist belts have the functions (1) to (5) above, depending on the material and structure, depending on the disease state.

Further, the conventional lumbar band is roughly classified from the functional aspect: (a) the lumbar vertebra is fixed so that the lumbar vertebra is not bent at all (b) the lumbar vertebra is restricted to prevent excessive flexion (c) ) There is one that compresses the entire lumbar region to increase the tension of muscle groups and reduce the load applied to the lumbar spine.

(A) is mainly worn when performing rehabilitation after performing lumbar spine surgery, and there are cast corsets, custom-made damen corsets, and the like. The main purpose of these is to fix the lumbar spine immovably, and the feeling of wearing is unfavorable because it gets stuffy during wearing and there is partial pressure.

[0005] (b) is intended for moderate back pain diseases and is called a flexible corset. It is a material and structurally designed in terms of how it has similar functions to (a) despite being an off-the-shelf product. However, these also have the same drawbacks as (a).

[0006] (c) is intended for mild low back pain diseases, and is made of a stretchable or soft stretchable material in the form of a belt, but it is functionally insufficient for preventing or treating low back pain.

On the other hand, there has been a recent change in medical coping methods for prevention and treatment of low back pain, and when the inflammatory period has passed, the body is actively moved, and as a result, deterioration of various muscles supporting the lower back is prevented. , On the contrary, they tend to encourage proper exercise to strengthen. For such medical coping methods, conventional lumbar band materials and structural designs cannot follow the movements of the lumbar spine, and when athletes with low back pain are exercising or those with low back pain are seriously injured. When working, the amount of exercise is much higher than usual, so you sweat a lot, you feel uncomfortable, and you cannot get a satisfactory product.

[0008]

[Problems to be solved by the device]

 The object of the present invention is a lumbar band used for the treatment and prevention of low back pain, which is particularly suitable for people with low back pain to wear during sports and heavy work. It allows anteflexion and suppresses dorsiflexion during spinal movements. It is to provide a highly permeable waist belt that has a support function and does not get stuffy even if a large amount of sweat is generated.

[0009]

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the present invention, a stretchable member that is made of a material that is difficult to stretch and has a breathability of 50 cc / cm ² · sec or more when it is not stretched and is connected to both ends of the back portion, respectively. It is made of a ventral part made of a material that has a breathability of 15 cc / cm ² · sec or more when not stretched, and a surface fastener is provided at the end of at least one abdominal part so that both ends of the abdominal part can be locked. Main body belt and elastic material that is fixed to the outer surface at the center of the back of the main body belt and extends in a V shape toward both ends of the main body belt, and has breathability of 15 cc / cm ² · sec or more when not stretched. An auxiliary belt with surface fasteners is provided at each end, and the width of the abdomen of the main body belt is made narrower than the width of the back.

[0010]

[Action]

In the present invention, the abdominal portion of the body belt is made of an elastic material and has a narrow width, which facilitates forward bending movements and allows abdominal breathing. Is made of difficult-to-stretch material and has a large width to prevent excessive flexion against dorsiflexion, and the breathability of the back part of the main body belt is 50 cc / cm ² · sec or more when not stretched, the main body belt The ventilation of the abdomen and the auxiliary belt is set to 15cc / cm ² · sec at no stretch and 50cc / cm ² · sec at 20% stretch, so the wearer's exercise amount is large and sweating is intense. In such a case, sweat permeates the main body belt and auxiliary belt and quickly diffuses to the outside. The air permeability in the present invention is the value obtained by the air permeability measurement method using the Frazier type tester specified in JIS L1096.

【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 waist band according to the present invention. The body belt 1 includes a dorsal position 2 that comes to the back when worn on the waist, and abdominal positions 3 and 4 that are connected to both ends of the dorsal part 2 and come to the belly when worn on the waist. Has been formed. The dorsal part 2 has a large width and is large enough to cover a large area on the back of the waist. The width of the abdominal portions 3 and 4 following the left and right of the dorsal portion 2 is selected to be smaller than the width of the dorsal portion. When the maximum width a of the back part 2 is, for example, 25 cm, the width b at the connecting portion between the back part 2 and the abdominal parts 3, 4 is, for example, 15 cm, and the width c near the tips of the abdominal parts 3, 4 is, for example, It is 9 cm.

A surface fastener 5 is provided at the end of one abdominal part 4 so as to be superposed on the other abdominal part 3 and engageable with it. The V-shaped open ends 8 and 9 of the two V-shaped auxiliary belts 6 and 7 are fixed to the left and right of the center of the back position 2, and the V-shaped end ends are fixed. Reference numerals 10 and 11 extend toward the abdominal portions 3 and 4 at both ends, and sharp end portions 10 and 11 are provided with surface fasteners 12 and 13, respectively. The sharp ends 10 and 11 are designed to be above the center of the abdominal positions 3 and 4. Stay covers 14 and 15 are attached to the left and right sides of the center of the back position 2, and stays 16 and 17 are held therein.

The material of the main belt which is difficult to stretch in the back position is 50 mm in width and length and has an elongation of 1% or more when 1 kg is loaded, preferably 2% or more, and 10% or less when 5 kg is loaded. It is preferably 8% or less, and it is preferable that it is flexible and flexible, has less fatigue even after long-term use, and has good air permeability. A double-sided knitted fabric is particularly suitable, and for example, a double Russell knitted fabric (so-called laminated Russell knitted fabric) can be used. Nylon, polyester, or a mixture of these is suitable as the type of fiber, and it is advantageous to use a structure in which both fabrics are connected with a 300d x 7 nylon monofilament yarn using nylon. . The texture and hardness of the double-sided knitted fabric are almost determined by the properties of the yarn in the thickness direction connecting the knitted fabrics on both sides, and the mesh size can be freely determined by selecting the knitting pattern, for example, 184 cc / It has a breathability of cm ² · sec and is several times as thick as the conventional breathable laminated fabric. The length is preferably such that the back side between the left and right iliac can be covered, and the width is 20 cm or more, preferably about 25 cm. The back surface of the waist is a region where sweating is particularly likely to occur, and if the breathability is less than 50 cc / cm ² · sec when not stretched, stuffiness is strong.

As the elastic material for the abdominal portion of the main body belt, it is preferable to use a material which is flexible, has a waist, has little fatigue even after long-term use, and has good air permeability. The surface is made of a material having a looped raised surface to which a hook-and-loop fastener is attached, and examples thereof include stretch nylon nylon / polyurethane nonwoven / cotton pile, stretch nylon pile / neoprene foam / stretch polyester three-layer laminate. The right and left sides are preferably overlapped with each other from the iliac to the abdomen, and the width is preferably 20 cm or less at the connecting portion with the dorsal part and about 8 cm at the center of the abdomen. The abdomen does not sweat much from the back, but if the breathability is less than 15 cc / cm ² · sec when it is not stretched, it does not provide a comfortable fit.

As a material for the auxiliary belt, a material having strong stretchability and good air permeability is used. For example, a kalami woven fabric using warp ester yarn 100d / 2, polyurethane yarn 1680d, and cotton nylon monofilament No. 3 yarn has expanded mesh spaces when stretched, and breathability is 38cc / cm ² · sec, 20% when not stretched. It becomes extremely large at 128 cc / cm ² · sec during extension. A width of 50 to 100 cm is suitable. If it is too narrow, it will bite into the body and cause pain, while if it is too wide, it will be larger than the width of the abdominal part of the body belt and will stick out. It is preferable that the modulus at 10 to 50% of the total of the two V-shaped belts is 1.8 to 4.0 kg, and preferably the modulus at 10 to 30% is 1.8 to 3.0 kg. 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, a sudden increase in modulus will not be obtained when a large load is applied, and the fixing force will be weak. In addition, there is a problem that the modulus value is not fixed outside this range and it cannot be sufficiently extended by the power of the aged. The auxiliary belt overlaps the dorsal and abdominal parts of the main body belt.If the ventilation is poor, the effect will be diminished even if a material with good ventilation is used for the dorsal and abdominal positions. Will end up. Therefore it is possible to breathability to the favorable wearing comfort of the whole lumbar zone by using more than a non-extended at ^{15cc / cm 2 · sec, 20} % elongation at 50cc / cm ² · sec. Further, by arranging the sharp ends 10 and 11 to be located above the center of the abdominal parts 3 and 4, a force for fitting the upper part of the dorsal part to the body when worn can be obtained.

2A and 2B are explanatory views of a mounted state of the waist belt of the present invention. Place the inside of the back part 2 of the main body belt 1 (the side opposite to the side where the auxiliary belts 6 and 7 are provided) on the back, and wrap it around the waist with the lower end of the main body belt 1 positioned just below the iliac bone. The other abdominal portion 4 is superposed on the abdominal portion 3 of the main body belt 1, and the surface fastener 5 of the abdominal portion 4 is fixed on the abdominal portion 3 by tightening. Next, both ends 10 and 11 of the auxiliary belts 6 and 7 are pulled and wound around the abdominal portions 3 and 4, and fixed on the abdominal portions 3 and 4 by hook-and-loop fasteners 12 and 13, respectively.

Generally, the greatest cause of low back pain is the displacement between the lumbar vertebra and the sacral vertebrae, but the body belt and the auxiliary belt press the abdomen to increase the abdominal pressure, and the force to push back the lumbar vertebra that is displaced forward To add.

According to the present invention, the width of the back part of the body belt is widened and the width of the abdominal part is narrowed, so that the forward bending can be facilitated and the increase in breathing due to the exercise can be facilitated. It is possible to perform abdominal inhalation, and the auxiliary belt attached to the center of the dorsal region ensures that the upper part of the dorsal region fits well to the body, and the dorsal part made of non-stretchable material prevents dorsiflexion. It has a sufficient supporting force to prevent excessive dorsiflexion, and since both the body belt and the auxiliary belt are made of highly breathable material, they do not cause stuffiness and feel comfortable to wear. It is extremely good and can be used comfortably even when returning to society or during sports.
