Description

The present invention relates to a hip joint supporter.

One of athlete's hip joint injuries is femoroacetabular impingement (FAI). At present, surgery is the only cure for FAI, and many athletes continue to compete while enduring pain.

Patent Literature 1 describes a hip joint supporter for preventing lateral displacement of the femoral head due to hip joint disease. This supporter has a main body made of an elastic material, and the main body consists of a waist belt that is wrapped around the waist and a thigh belt that is wrapped around the thigh.

Japanese Patent No. 3986632

Since the main cause of FAI is the collision between the femur and pelvis that occurs during hip joint movement, limiting the range of motion of the hip joint (especially forward flexion) is effective in alleviating symptoms and preventing aggravation. is. However, since the supporter described in Patent Document 1 is attached so as to cover the entire pelvis and hip joints, it is possible to prevent the femoral head from moving outward, but since the main body is made of a stretchable material, the hip joints have a movable range. can hardly be restricted.

SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a hip joint supporter capable of limiting the movable range of the hip joint simply by wearing it.

The present invention is a hip joint supporter comprising a fixing part fixed to the body of a wearer and an inguinal belt formed so as not to be substantially stretchable and having both ends fixed to the fixing parts.

The hip joint supporter of the present invention can easily limit the range of motion of the hip joint by wearing it.

It is a figure which shows the supporter for hip joints which concerns on 1st embodiment of this invention. It is a figure which shows an example of the mounting state of the supporter for hip joints. It is a figure which shows the restriction|limiting effect|action of hip-joint flexion by the same hip-joint supporter. It is a figure which shows the modification of the supporter for same hip joints. FIG. 4 is a diagram showing a hip joint supporter according to a second embodiment of the present invention;

A first embodiment of the present invention will be described with reference to FIGS. 1 to 3. FIG. The hip joint supporter 1 of this embodiment includes a waist belt (fixed portion) 10 fixed to the body of the wearer and an inguinal belt 30 attached to the waist belt 10, as shown in FIG.

The waist belt 10 includes a strip-shaped main body 11 and a buckle 12 attached to the main body 11 . By passing one end of the main body 11 through the buckle 12, the waist belt 10 becomes looped and can be fixed to the wearer's waist. By changing the positional relationship between one end and the buckle 12, the size (diameter) of the annular shape can be changed, and the size can be adjusted according to the wearer's waist circumference. A hook-and-loop fastener (fixing portion) 13 is attached to a certain range in the longitudinal direction of the main body 11 to fix the end portion of the groin belt 30 .

The groin belt 30 has a main body 31 and hook-and-loop fasteners 32 provided at two locations on the main body 31 . The hook-and-loop fastener 13 and the hook-and-loop fastener 32 need only be detachable from each other, and either one may be on the hook side and the other on the loop side. The main body 31 is formed so as not to be substantially stretchable.
In the present invention, "substantially non-stretchable" means that the elongation rate is 5% or less when a force of 10 N is applied in the longitudinal direction of the main body 31 . Examples of materials that achieve such physical properties include natural and synthetic leathers and plain weave fabrics.

The operation of using the hip joint supporter 1 configured as described above will be described.
First, the hook-and-loop fasteners 32 on both ends of the groin belt 30 are attached to the hook-and-loop fasteners 13 of the waist belt 10 . As a result, both ends of the groin belt 30 are fixed to the waist belt 10, and the length of the groin belt between the fixed parts is adjusted. The length of the groin belt between the fixed parts is determined based on the range of motion of the hip joint to be set.

Next, the wearer passes the leg on the side limiting the movable range through the loop formed by a part of the waist belt 10 and the groin belt 30 between the fixed parts, and extends the waist belt 10 to the vicinity of the waist. move. Finally, one end of the main body 11 is passed through the buckle 12, and the waist belt 10 is fastened according to the size of the waist.

In the attached hip joint supporter 1, both ends of the groin belt 30 are fixed to a part of the hook-and-loop fastener 13 of the waist belt 10 on the back side. The intermediate portion of the groin belt 30 is arranged on the front side of the thigh. When the wearer bends the thigh forward in this state, as shown in FIG. Since the groin belt 30 does not substantially stretch and contract, it does not stretch to follow the flexion of the thigh, and limits the range of motion of the hip joint on the side to which the groin belt 30 is attached. The movable range limited by the groin belt 30 can be adjusted within a certain range by adjusting the fixing positions of both ends, the length of the intermediate portion, and the like.

As described above, when the hip joint supporter 1 is used with the groin belt 30 appropriately attached to the waist belt 10, it is possible to easily limit the range of motion of the hip joint and suppress the collision between the femur and the pelvis. . As a result, it can contribute to symptom relief and suppression of exacerbation of FAI. In addition, it can be worn over clothing, and exercise while wearing it is also possible.

In this embodiment, the manner in which the groin belt is attached to the waist belt is not limited to the hook-and-loop fastener described above.
In the modified hip joint supporter 1A shown in FIG. 4, the groin belt 40 has a first belt 41 and a second belt 42 fixed by sewing to the fixed portions 15 and 16 of the waist belt 10 at one end. A steplessly adjustable buckle 43 is attached to the first belt 41, and by passing the end of the second belt 42 through the buckle 43, the first belt 41 and the second belt 42 can be A single groin belt 40 is fixed to the waist belt. The length of the groin belt 40 between the fixing parts 15, 16 can be adjusted to a desired value by changing the fixing position of the second belt 42 to the buckle.

A second embodiment of the present invention will be described with reference to FIG. In the following description, the same reference numerals are given to the same configurations as those already described, and redundant descriptions will be omitted.

FIG. 5 is a diagram showing a hip joint supporter 51 of this embodiment. The hip joint supporter 51 includes a waist belt 52 and a groin belt 55 .
Four buttons are attached to the waist belt 52 as fixing portions. The four buttons consist of two buttons 53A and two buttons 53B. Button 53A is used to attach the groin belt to the right leg. Button 53B is used to attach the groin belt to the left leg.

Groin belt 55 has a plurality of buttonholes 56 and a rubber pad 57 . The buttonholes 56 are formed side by side at regular intervals on both ends of the groin belt 55 . The rubber pad 57 is attached to the central portion of the groin belt 55 in the longitudinal direction. The width dimension of the rubber pad 57 is larger than the width dimension of the groin belt 55 .

When using the hip joint supporter 51 , the user passes one of the buttons attached to the waist belt 52 through button holes at both ends of the groin belt 55 . For example, the button 53A is passed through the button hole 56 when the movable range of the right leg hip joint is desired to be restricted.
Groin belt 55 is fixed to waist belt 52 at a position through which button 53A or 53B is passed. Although the length of the groin belt 55 itself does not change, the length between the fixed parts of the groin belt can be adjusted by changing the button holes through which the buttons are passed.

The groin belt 55 is worn so that the rubber pad 57 contacts the leg. While the hip joint supporter 51 is being worn, the elastic deformation of the rubber pad enhances the adhesion to the contact portion and at the same time cushions the excessive pressure of the groin belt, thereby suppressing skin damage at the attachment site.

As with the hip joint supporter 1 of the first embodiment, the hip joint supporter 51 of the present embodiment can also easily limit the range of motion of the hip joint to suppress collision between the femur and the pelvis.

In addition, since the right leg button 53A and the left leg button 53B are provided as buttons for fixing the groin belt, one supporter can be applied to limit the range of movement of either leg. With two groin belts, it is also possible to limit the range of motion of the legs.

Furthermore, since a plurality of buttonholes 56 are provided, it is easy to adjust the length between the fixed parts of the groin belt.
In addition, in the groin belt 55, since the rubber pad 57 that presses the leg is wider than the groin belt 55 itself, the contact area with the leg is increased, and excessive local pressure can be prevented.

In this embodiment, an example in which the waist belt has buttons and the groin belt has buttonholes has been described, but the waist belt may have buttonholes and the groin belt may have buttons. The fixing means is also not limited to the button, and the hook-and-loop fastener described in the first embodiment may be used.
If the waist belt is provided with buttons, the buttons may be located on either side.

The rubber pad 57 may be the same width as the groin belt or may be omitted. Instead of the rubber pad 57, an elastomer pad may be used.
Adjacent buttons 53A and 53B may be combined into one common button and used both when worn on the right foot and when worn on the left foot.

Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the above embodiments. Various changes can be made to or deleted from components.

For example, the fixing portion to which the groin belt is fixed may not be provided on the waist belt described above. In other words, the waist belt is not essential if the leg can be compressed by the groin belt. Since the groin belt can stably press the legs by being fixed at both ends, instead of the waist belt, a belt to be fastened to the chest or a belt to be hung on the shoulder may be provided with a fixing part. Furthermore, instead of taking the form of a belt, only the fixing portion may be fixed to a certain position on the wearer's body surface using an adhesive pad or the like.

The groin belt in this embodiment may be made of a material that is elastically deformable as long as it meets the definition of "substantially non-stretchable" above. For example, the groin belt is made of a material that has an elongation of 2% when a force of 10N is applied in the longitudinal direction and an elongation of 10% when a force of 15N is applied in the longitudinal direction. may
