Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a sacroiliac joint fixation belt for preventing sacroiliac joint sway.

[0002]

2. Description of the Related Art A conventional sacroiliac joint fixing belt comprises a belt body 1 and a splint portion 2 as shown in FIGS.
The splint portion 2 has a velvet fastener 3 provided on the back side thereof.
It is fixed to the inner surface of the belt body 1 via.

A buckle 4 is provided at one end of the belt main body 1, and the buckle 4 is locked and attached to any one of a plurality of small holes 5 provided at the other end of the belt main body 1. . Therefore, it is necessary to prepare the belt main body 1 having various lengths corresponding to the waist circumference of the wearer.

Further, the splint portion 2 serving as a fixed portion of the sacroiliac joint
Is a synthetic resin plate, a hard member 6 such as hard polyurethane covered with a cloth 7, and therefore does not match the elasticity of the muscles of the lower back and has a strong feeling of pressure and wearing, and the splint portion 2 is fixed from the fixed position. There was a problem that the motility such as coming off was reduced, and because the breathability was poor, sweat accumulated on the splint and the waist cooled.

When the position of the splint portion 2 is not appropriate at the time of mounting, it is necessary to once dismount the belt main body portion 1 to remove the splint portion 2 and then move it to a desired position and mount it again. It took extra effort and time.

SUMMARY OF THE INVENTION It is an object of the present invention to obtain a sacroiliac joint fixation belt that can be easily worn and has a comfortable fit.

[0007]

A belt main body having a buckle at one end and a velvet fastener at the other end, and a splint attached to the belt main body via a belt loop, The main body is made of neoprene rubber covered with bi-directional stretchable pile fabric, and the splint part is made of polyester fiber felt containing far-infrared radiation ceramics, polyurethane foam, polyethylene foam three-layer structure, polyester fiber. A belt loop was provided on the polyethylene foam layer side of the three-layer structure by covering with a felt and a bi-directional stretchable pile fabric.

[0008]

Since the sacroiliac joint fixing belt of the present invention has the above-mentioned structure, the belt main body portion is stretchable, and the locking position of the velvet fastener provided at the end portion is changed.
The tightening pressure on the body can be adjusted at will, and the splint part can circulate the synovial fluid of the sacroiliac joint by buffering the body pressure of the wearer during exercise and the pumping action based on the cushioning property of the exercise and splint part. It does not absorb moisture to the inside of the splint even if it stimulates sweat,
It releases moisture and relieves sacroiliac joint pain.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings.

The sacroiliac joint fixation belt 10 of this invention is shown in FIG.
As shown in FIG. 3, it comprises a belt body 11 and a splint portion 2, and the splint portion 12 is attached to the inner surface of the belt body portion 11 via a belt loop 13 provided on the back side thereof.

A buckle 14 composed of a square ring is provided at one end of the belt main body 11, and a velvet fastener 15 is provided on the outer surface at the other end of the belt main body 11 so that the belt main body 11 other than the belt main body 11 inserted into the buckle 14 is inserted. The end is bent and brought into contact with the outer surface side, and is locked by the velvet fastener 15.

The belt body 11 is made of a neoprene rubber 16 having a high elasticity and durability as a core material, and the entire surface of the belt is a pile fabric 17 which expands and contracts in both horizontal and vertical directions, for example, nylon 80.
%, Polyurethane 20% bi-directionally stretchable pile fabric 17 is used as the side material, resulting in a waist circumference of 110.
It can handle up to about 50 cm or less.

As the splint portion 12, a polyester fiber felt 21 is formed on the entire surface of a three-layer structure composed of a polyester fiber felt layer 18 containing a mixture of far-infrared radiation ceramics, a polyurethane foam layer 19 and a polyethylene foam layer 20. The entire surface is covered with a pile fabric 22 having bidirectional stretchability similar to that of the side of the belt main body 11, and the belt loop 13 is provided with the polyethylene foam layer 20 side of the three-layer structure as the back surface. It is provided.

As a result of various studies on the splint portion 12, however, as the polyester fiber felt layer 18 mixed with far-infrared radiation ceramics, a polyurethane foam layer 19 having a thickness of about 2 mm having heat retention and cushioning properties is used. Polyethylene foam layer 2 has a thickness of approximately 8 mm and is highly elastic.
0 means compressive strength 0.8 kg / cm ² , compression set 3%
Approximately 13 mm, which does not deform even when used for a long time
A thick three-layer structure is suitable, the entire surface of which is covered with an elastic polyester fiber felt 21 having a thickness of approximately 3 mm, and the entire surface thereof is bi-directionally stretchable pile fabric 22. It was found that the size of 8 cm × 28 cm, which was covered with, was suitable for the sacroiliac joint of any person.

[0015]

As described above in detail, the sacroiliac joint fixing belt of the present invention is attached to the belt main body through the belt loop and the belt main body having the buckle at one end and the velvet fastener at the other end. The belt body is made of neoprene rubber covered with bi-directionally stretchable pile fabric, and the splint portion is made of polyester fiber felt containing far-infrared radiation ceramics, polyurethane foam, A three-layer structure of polyethylene foam is covered with a polyester fiber felt and a bidirectional stretchable pile fabric, and a belt loop is provided on the polyethylene foam layer side of the three-layer structure. The bi-directional stretchable pile fabric used for the splint has excellent hygroscopicity at the part that directly contacts the skin, and the belt body has its elasticity. It can be adjusted tightening put pressure on the body at will by changing the locking position of the velvet fastener provided on the part.

Further, when the splint portion is moved to a proper position after being mounted, the splint portion can be easily slid to change its position by loosening the belt body. The splint is prevented from being deformed due to tightening or skeleton irregularities caused by wearing for a long period of time, and the body pressure during exercise of the wearer is buffered. It promotes the circulation of synovial fluid in the sacroiliac joint, and even during sweating, it diffuses moisture without absorbing moisture inside the splint, and since the splint retains heat due to the presence of far-infrared radiation ceramics, Low back pain from the iliac joint deviation and radiation pain to the lower limbs, as well as hip joint pain due to the deviation of the iliac joint fossa and femoral head from the sacroiliac joint deviation, and physiological pain due to the strain of the large and small psoas muscles It was found that it was effective against chronic low back pain by alleviating the above symptoms and preventing lowering of the lumbar region.
