[Industrial applications]

 INDUSTRIAL APPLICABILITY The present invention relates to a wearing tool used for the prevention and treatment of low back pain, and particularly, "handling heavy objects", "bad posture such as middle waist", "restrained sitting posture such as vehicle driving" and "whole body such as special vehicle". The present invention relates to a lumbar orthosis for prevention and treatment of occupational low back pain caused by work modes such as "vibration".

[0002]

[Prior Art]

 BACKGROUND ART Conventionally, various lumbar spine corsets have been proposed as a main therapeutic device for low back pain, which is known as a low back pain corset.

For example, an elastic core material is used for the back of the waist, and the improvement of the adhesion and the fit property by tightening and compressing the entire waist is embodied. JP-B-58-50900 and JP-B-58-54096. Is mentioned.

[0004] In addition, as a low back pain belt with a pelvic belt, and the effect of this combination is embodied as a low back pain treatment device, there is JP-B-61-43474, which discloses compression of abdominal oblique muscle and improvement of wearability. As an example, there is Jitsukaihei 2-82322.

Further, regarding improvement of wearability such as prevention of sliding up, JP-B-60-38979 and JP-B-60-38980 can be mentioned.

On the other hand, regarding the preventive effect of low back pain by a belt, a corset and the like, “internal and external oblique muscles and transverse abdominal muscles are important as muscle groups involved in the decompressing effect of the lumbar spine by intraperitoneal pressure. [Morris, JM et al .: Role of the trunk in stability of the spine, J. Bone and Joint Surg. 43-A (1961) pp.327-351] The average intra-discal pressure is reduced by 26-35% when the corset is worn compared to when the corset is not worn. ”[Hiroshi Kanematsu, et al .: Measurement of inter-vertebral disc internal pressure (3rd report), Journal of the Journal, 45 (1971). pp.855-856] In addition, “When a pelvic belt is worn and a spinal column function test is performed, the abdominal muscle test using the upper abdominal muscle group is significantly improved. It is useful to wear the pelvic belt at the pelvic position. Improvement in low back pain is observed when used. ”[Yoki Taniguchi, et al .: Industrial clinical medicine for lower back disorders] Study (Part 1), there is a Japan Society for Occupational Health lecture Collection (1982) pp.198-199] pointed out, such as.

Common examples that affirm these findings include the abdominal band of weight-lifting athletes, the “exposed” abdominal band when the waist is sprained, and the pelvic belt of Taniguchi et al.

[0008]

[Problems to be solved by the device]

 Thus, with regard to the treatment and prevention of low back pain, the corset effect of the above-mentioned known examples as a therapeutic device is not excluded in the preventive effect, but when the low back pain preventive effect of the device is more important, The following problems still remain. 1. Disuse atrophy of the trunk muscles occurs due to the fixation of the lower back. 2. Poor mobility and workability. 3. Tighten your belly. 4. It's hot. Therefore, the wide corsets that are often seen in conventional cases are used only when hospitalized or at home, and there is a difficulty in using them when working.

In recent years, occupational low back pain has been increasing due to an increase in work density accompanying mechanization of work, and preventive measures against it have been strongly demanded. As the causes of this occupational low back pain, "handling of heavy objects", "bad posture such as middle waist and forward leaning posture", "long restrained sitting posture" and "whole body vibration" are important. Among the preventive measures, the back pain prevention belt has been considered as a part of the “work management” measures that are important according to the improvement of the “environmental management”.

There, “the back of the waist has a large amount of muscle and has strong bony support, but the front abdominal wall is weak. Therefore, the back of the waist does not need to be reinforced with cloth, and only the columns are used to wrap the abdominal wall. It has a meaning. ”[Yoshio Oi: Spinal support device (trunk instrument), back pain (medical and dental drug edition; Tokyo, 1979) pp.223-231] From the viewpoint of industrial hygiene, it is expected that a back pain prevention belt suitable for the work mode will be proposed.

The present invention has been made in view of the above circumstances, and provides a lumbar orthosis that solves the above problems, has a sufficient abdominal pressure, and has a minimum movement restriction during work. It is intended to be provided. At the same time, it is an object of the present invention to obtain a lumbar orthosis which is constantly effective as a therapeutic device.

[0012]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention relates to a lumbago worn on the pelvis, in which a waist belt main body having a predetermined band width in consideration of mobility is sewn on a non-stretchable mesh fabric. Members and a waist back with rubber slip-up prevention pads, armpits with elastic pads on both sides that are sewn to elastic cloth for wrapping the pelvis, and shape-retaining bone members. It is composed of abdominal parts extending to both ends of the belt, one pair of upper and lower tightening belts is provided at one end thereof, and abdominal wall abutting part of another member is provided at the locking through ring side at the other end. In other words, the lumbar device is secured by the tightening belt, which has a face tape having male and female switched from the middle on one side thereof and is fixed by being folded back through the through ring.

[0013]

[Action]

 Each part (material) of the lumbar spine brace configured as described above has the following functions. The elastic fabric on the side part applies planar compression along the body shape in the length direction of the waist belt, and assists the stabilization of the lumbar spine and good wearability. The locking by the tightening belt has a degree of freedom because it is the fastening of the surface tape, which enables the stepless adjustment of the tightening force. The abdominal wall abutment is a compression support of the abdomen, which promotes reduction of intra-discal pressure due to abdominal pressure and prevents the lumbar / sacral vertebra junction from stumbling. The anti-slip rubber pad and the tightening belt assist the fit without shifting to the pelvis position and reduce the movement restriction when wearing.

【Example】

 An embodiment of the present invention will be described with reference to the accompanying drawings. 1 is a front view of a lumbar orthosis according to the present invention, and FIG. 2 is a rear view of the same. As shown here, the waist belt body (1) is a belt-shaped body having a predetermined width in consideration of movability, and when worn, the waist back part (2) is slightly wider in the center of the length direction and both sides thereof. Side portions (3) and (3) and abdominal portions (4) and (5) at both ends, and a pair of upper and lower tightening belts (6), ( 7), and the other end (5) is provided with locking tools (9), (9) and locking through rings (8), (8), and an abdominal wall abutting part (10). Has been done. About 10 to 15 cm is effective as the predetermined band width, but it is acceptable as long as it covers the pelvic position and does not press the seasonal ribs when bending forward.

The waist back (2) is composed of a column member (11) sewn on a non-stretchable mesh material, for example, a nylon mesh, and an anti-slip rubber pad (16), and is mounted symmetrically around the spine. Preferably.

The armpits (3), (3) are made of an elastic cloth that expands and contracts only in the length direction and a rubber-repelling prevention rubber pad (16), (16) of the same quality as the rubber pad sewn on the elastic cloth. It is preferable to wear it so as to wrap around the pelvis. Here, the above-mentioned anti-slip rubber pads (16), (16) are made of a wart-like rubber material, but have a large friction coefficient and can be appropriately sewn to fabrics. Any material can be used.

The abdominal parts (4) and (5) are made of non-stretchable mesh material which is the same as the back of the waist through the shape-retaining bone members (12) and (12) and reach both ends of the belt. Is. The tightening belts (6) and (7) at one end (4) of the abdominal position have face tapes (13) and (14), one side of which is switched between male and female. The other surface may be made of the same material as the bone member (12). Further, the other end (5) is provided with locking tools (9), (9) and locking through rings (8), (8), which are provided by tightening belts (6), (7). The locking is performed by fastening the surface tapes (13) and (14) by folding back through the through rings (8) and (8).

The abdominal wall abutting portion (10) is made of a material having a high shape retention property and having a vent hole (15), and forms a compression surface for supporting abdominal pressure. For example, a leather product having punched holes on one surface is preferable.

FIG. 3 is a front view of the lumbar spine brace according to the present invention, and FIG. 4 is a rear view of the same. The lumbar orthosis described above is such that the lumbar back (2), the side parts (3), (3), the abdominal positions (4), (5) and the abdominal wall contact part (10) are located at each body part, Although it is worn by wrapping it around the waist pelvis, it is preferable to adjust and adjust the tightening position and tightening force of each pair of upper and lower tightening belts (6) and (7).

In particular, it is desired that the lower belt (7) has a tightening position in the lower iliac region and has a slightly stronger tightening force than the upper belt (6). In this way, it is possible to apply an appropriate compression force and advantageously prevent the climbing during movement.

The effect of improving the lower back pain by wearing the above-mentioned lumbar orthosis has been demonstrated in the industrial field, and an example of the survey result is that it is worn for 7 months to 10 tons per day by a heavy load carrier for 6 months. The effect of improving low back pain was 60 to 70%.

[0022]

[Effects of the Invention] As described in detail above, the lumbar orthosis according to the present invention takes into consideration the working mode in order to prevent occupational low back pain. It has excellent wearability such as prevention of swelling and has the advantage that it can easily exert voluntary back muscle strength and easily apply abdominal pressure, reducing the load on the lumbar region due to work operations, stabilizing the lumbar spine and protecting the lumbar spine. It has a remarkable low back pain prevention effect. In particular, the effect of preventing the onset of acute low back sprains is great, and it can be expected to contribute to the reduction of absenteeism due to low back pain.

Further, by mounting the pelvis at the pelvic position, it is possible to eliminate the pressure on the ribs due to the upper end of the waist belt when the waist is bent forward, and to eliminate the discomfort of tightening. It is also very effective as a therapeutic device for coping with lumbago beyond the above-mentioned preventive effect on lumbago, especially for stabilizing the lumbar-sacral joint and reducing the intervertebral disc pressure, and for relieving lumbago and protecting the lumbar spine. Highly effective therapeutic effect.
