Description

  The present invention relates to a meniscus correction belt that moderately presses a meniscus to protect the meniscus, and alleviates knee pain caused by meniscus displacement and corrects the position of the meniscus.

  In the knee joint between the femur and tibia, there are two meniscuses on the inside and outside of the knee to absorb the impact received from the thigh and stabilize the knee joint for smooth movement Yes. The meniscus is easily displaced due to aging, sports injury, etc. When the joint space narrows with the displacement of the meniscus, the bone may harden or osteophytes and bone crests may cause pain in the knee. In particular, when stress is applied to the outer muscle group due to aging or sports injury, the tibia is distorted, so-called `` Knee out Toe in '', and the meniscus is displaced forward of the knee in an attempt to correct this distortion. It was. With this displacement, the medial joint space narrowed, and pain often occurred in the medial joint.

Conventionally, various orthoses have been proposed in order to protect and correct knee joints and relieve pain in knee joints. For example, an elastic patella fixing portion having a hole for exposing the patella, and a connecting belt provided at both ends of the patella fixing portion, the patella fixing portion being applied to the patella, and the connecting belt being applied to the patella with an appropriate pressure (See Patent Document 1), and the two band pieces attached to the upper and lower knees are connected to the longitudinal center of the band piece and applied to the back of the knee. It is composed of a rubber base with a knee backing to be peeled off, a hook-and-loop fastener that detachably connects both ends of each band piece, and a magnet disposed on the inner surface of the band piece. In some cases, blood circulation is promoted by attaching the magnet to the periphery of the knee joint (see Patent Document 2).

  However, although the thing of the above-mentioned patent document 1 can fix a patella and can correct a knee joint, it does not press a meniscus directly and cannot protect or correct a meniscus. Moreover, although the thing of patent document 2 is suitable for improving the blood circulation around a knee joint and relieving the pain of a knee joint, like the patent document 1, it protects and corrects a meniscus. There was no effect to do.

  Therefore, the present invention provides a meniscus correction belt that protects the meniscus and prevents and corrects meniscus displacement, and suppresses or alleviates knee pain caused by meniscus displacement. The purpose is to provide.

  In order to achieve the above object, the meniscus correction belt of the present invention is a first elastic pressing member that presses the inner meniscus against a knee contact surface disposed in front of the knee of a belt-like body attached to the lower part of the patella. A member and a second elastic pressing member that presses the outer meniscus are attached, and the band-shaped body is formed of an elastic rubber sponge, and the longitudinal direction of the band-shaped body is formed at both ends of the band-shaped body. A long hook-and-loop fastener is attached to the belt, and the fastening strength of the belt-like body and the pressing strength of the first elastic pressing member and the second elastic pressing member are obtained by expanding and contracting the belt-like body and changing the connection position of the hook-and-loop fastener. Adjustment is preferred.

  By forming as described above, the inner meniscus and the outer meniscus can be directly pressed by the elastic pressing members, and the displacement of the meniscus can be effectively prevented and corrected. In particular, since the first and second elastic pressing members are disposed in front of the knee where the meniscus is easily displaced and presses the inner meniscus and the outer meniscus respectively, the two meniscuses are effectively structured with a simple structure. Can be protected and straightened.

  In addition, the band-shaped body is formed of a rubber sponge that can be expanded and contracted, and the knee fastening strength of the belt-shaped body and the meniscus pressing strength of each elastic pressing member can be adjusted by changing the connection position of the hook-and-loop fastener, and the state of the meniscus Accordingly, the optimum tightening strength and pressing strength can be obtained.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a perspective view of a meniscus correction belt showing one embodiment of the present invention, and FIG. 2 is an explanatory view of a state in which the meniscus correction belt is attached.

  The meniscus correction belt 1 includes a belt-like body 2 attached to the lower portion of the patella 20, and a first elastic pressing member 3 a and a second elastic pressing member 3 b attached to the knee contact surface 2 a of the belt-like body 2. ing.

  The belt-like body 2 is formed of a rubber sponge that can be expanded and contracted, and is formed so that the width gradually increases from both ends toward the center, and the width gradually increases from the center that becomes the widest toward the center. Is formed to be narrow.

  A hook-and-loop fastener 4 is attached to both ends of the belt-like body 2 so as to detachably connect the both ends. The hook-and-loop fastener 4 is a well-known one composed of a first cloth piece 4a having a hook-like protrusion on one surface and a pile-like second cloth piece 4b. The first cloth piece 4a is formed in a rectangular shape, It is attached to one end of the belt-like body 2 on the knee contact surface 2a side. The second cloth piece 4b is formed in a rectangular shape that is longer in the longitudinal direction of the belt-like body 2 than the first cloth piece 4a, and is attached to the other end of the belt-like body 2 on the outer surface 2b side.

  The first elastic pressing member 3a and the second elastic pressing member 3b are formed of a rectangular sponge or urethane having appropriate flexibility, and have a predetermined interval at the center of the knee contact surface 2a of the belt-like body 2. Can be installed after emptying.

  As shown in FIG. 2, the meniscus correction belt 1 formed as described above abuts the first elastic pressing member 3a on the inner meniscus 21a and the second elastic pressing member 3b on the outer meniscus 21b. The first and second cloth pieces 4a and 4b of the hook-and-loop fastener 4 attached to both ends of the belt-like body 2 are used, the first elastic pressing member 3a is the inner meniscus 21a, and the second elastic pressing member 3b. Are attached to the lower side of the patella 20 by being connected on the back side of the knee so as to press the outer meniscus 21b.

  As described above, the meniscus correction belt 1 according to the present embodiment can be easily attached to the lower part of the patella 20 and can be attached even in a state in which shoes are worn. Further, the belt-like body 2 is formed so that the width gradually increases from both ends toward the center side, and is formed so that the width gradually decreases from the center side where the width is widest toward the center portion. Therefore, when the meniscus correction belt 1 is attached, the upper end 2c of the belt-like body 2 is arranged so as to follow the curvature of the patella 20, and even after the meniscus correction belt 1 is attached, It can be bent and stretched easily. Furthermore, since the belt-like body 2 is formed of a rubber sponge that can be expanded and contracted, and the connection position of the hook-and-loop fastener 4 can be changed, the tightening strength of the belt-like body 2 and the first elastic pressing member 3a and the second elastic pressing member 3b can be changed. The pressing strength can be adjusted, and the optimum tightening strength and pressing strength can be easily obtained according to the state of the meniscus 21a, 21b.

  Note that the width of the belt-like body may be set as appropriate, the width may be formed wide, the knee joint may be covered widely, and a cushion that contacts the back of the knee may be provided. Further, the material and shape of the belt-like body and the elastic pressing member are not limited to the above-described embodiments, and any material can be used as long as it can press the meniscus satisfactorily.

It is a perspective view of the meniscus correction belt showing an embodiment of the present invention. It is explanatory drawing of the state which mounted | wore the meniscus correction belt.
