Description

  The present invention relates to a supporter used for alleviating symptoms of Osgood Schratter disease.

Osgood Schratter disease is a disease in which the rough surface of the tibia is raised or detached, and the quadriceps, which is the extensor muscle of the knee joint, is largely and frequently contracted by exercise, causing the patella and patella. The cause is that mechanical traction force is applied to the rough surface of the tibia through the ligament.
When it is desired to continue exercise while having such Osgood Schlatter disease, it is common to use a supporter that reduces the traction force applied to the rough tibial surface. Such a supporter is used for a portion up to the rough surface of the tibia as shown in the following patent document, and is a device that presses a pad made of an elastic material or a hard material directly under the patella, quadriceps, or patella. .

By the way, the sports in which Osgood Schlatter disease occurs are baseball, soccer, athletics, and volleyball, and do not occur in judo, swimming, and cycling. In these cases, the quadriceps muscle is large and frequently contracts, but it does not occur in the latter judo, swimming, or bicycle, so there are causes other than traction of the rough tibial surface by the quadriceps muscle. It is thought that there is. Considering the difference between the two, baseball, soccer, athletics, and volleyball received a strong impact from the ground, while judo, swimming, and bicycles did not receive a strong impact from the ground. It can be inferred that it contributes to the occurrence. That is, in order to improve Osgood Schlatter disease, it is important to reduce the impact on the rough tibial surface transmitted from the ground during exercise. It is not considered sufficient to reduce this impact.
In view of this, an object of the present invention is to provide a supporter for improving Osgood Schlatter disease that has a function of reducing the impact on the rough surface of the tibia.

In order to solve the above problems, the present invention has the following configuration.
According to the first aspect of the present invention, a hard material formed of a hard material having a back surface formed so as to be matched with a lower knee surface portion including a rough tibial surface portion of a leg worn by a user. Osgood Schlatter disease supporter comprising a pad and a fastening belt, which is made of a low-stretch or non-stretchable belt for holding the hard pad, for fixing the hard pad to the lower knee surface portion, and which can adjust a tightening force. It is.
According to a second aspect of the present invention, in the Osgood Schlatter supporter, a thin shock absorber is attached to the back surface of the hard pad.

The invention according to claim 1 pays attention to pressing a rough surface of the tibial bone, which is a lower part of the portion supported by the conventional supporter, and a hard pad covering the lower knee surface portion including the rough surface of the tibial molds. By being formed by this, the hard pad fits snugly on the surface below the knee, and by fixing this with a belt that does not expand and contract, a part of the impact transmitted through the tibia from the ground is dispersed to the hard pad side, The impact on the rough tibial surface can be reduced.
In addition, when actually tested by a plurality of patients with Osgood Schlatter disease, a marked improvement in symptoms was seen as compared with conventional Osgood supporters.
The invention according to claim 2 can alleviate the pain caused by friction when the hard plate directly touches the skin by sticking a thin shock absorber on the back surface of the hard pad.

It is a perspective view of the supporter for Osgood Schlatter disease which concerns on embodiment. It is sectional drawing which shows the use condition of the supporter for Osgood Schlatter disease which concerns on embodiment.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view of an Osgood Schlatter supporter X (hereinafter referred to as OS supporter X) according to the present embodiment. The OS supporter X includes a hard pad 10, an impact absorbing material 20, and a fastening belt 30.
The hard pad 10 is a plate made of hard plastic and has a thickness that cannot be easily deformed. The back side of the hard pad 10 is formed by molding so as to fit the surface of the lower knee part covering the rough tibial surface of the leg suffering from Osgood Schratter disease. The hard pad 10 can be formed of various materials such as metal and wood as long as it is a hard material that does not easily deform.
The shock absorber 20 is a thin sheet formed of silicon rubber, polyethylene foam, or the like, has a shape that substantially matches the back surface shape of the hard pad 10, and is bonded and fixed to the back surface of the hard pad 10.
In addition, elongated holes 21 and 22 that are elongated rectangular through holes for allowing the fastening belt 30 to pass therethrough are formed in the vicinity of both ends of the plate formed by the shock absorber 20 and the hard pad 10.
The fastening belt 30 is a flat flat belt formed by knitting nylon fibers. The belt is fastened to one end side, and a buckle 31 for adjusting the fastening force is fixed. As the fastening belt 30, various materials can be adopted as long as they are low stretchable or non-stretchable materials. In addition to the buckle 31, various fastening members can be used as long as they can be bound, and a hook-and-loop fastener or the like can also be used.

  Next, the usage method and operation of the OS supporter X having the above configuration will be described. First, as shown in the cross-sectional view of FIG. 2, the user brings the shock absorbing material 20 into contact with the position where the mold is taken so as to cover the tibial rough surface S portion that is the starting point of the patella ligament J. In this state, the fastening belt 30 is passed through the long hole 21 so that the buckle 31 is located on the surface side of the hard pad 10, wound around the upper part of the shin, and passed through the surface from the back side to the opposite long hole 22, The end is fastened to the buckle 30 so that it does not move. Thereby, the hard pad 10 with the shock absorbing material 20 attached to the back surface can be fixed so as to cover the tibial rough surface S as shown in FIG. The fastening belt 30 is formed of a material that does not substantially expand and contract, and by firmly fastening and fixing, the hard pad 10 does not shift due to movement and the pressing force does not decrease.

  In this way, when the OS supporter X is mounted and exercise is performed and an impact from the ground is received by the sole of the foot, the impact rises along the tibia B. The part is dispersed by being transmitted to the hard pad 10, and the impact transmitted to the tibial rough surface S portion is reduced. As a result, peeling or bulging of the tibial rough surface S hardly occurs, and the symptoms of Osgood Schlatter disease are alleviated. On the other hand, in the conventional supporter described in Patent Document 1 and the like, since the tibial rough surface S is pressed above the surface of the tibial rough surface S, the impact from the ground is directly transmitted to the tibial rough surface S. The relaxation is not good. Furthermore, although the belt-like supporters described in Patent Documents 1 to 3 can also press the tibial rough surface S portion, the pad portion fits snugly on the lower knee portion surface covering the tibial rough surface S as in the present invention. Since they do not match, the impact transmitted to the rough tibial surface cannot be well distributed to the pad even if used in this way. In this regard, in the present invention, the hard pad 10 is formed by molding the surface of the lower knee covering the rough tibial surface S for each user, so that the impact transmitted to the rough tibial surface is well dispersed in the hard pad 10. be able to.
