Description

  The present invention relates to a wrist joint supporter, and particularly to a wrist joint supporter suitably used as a supporter for ganglion compression, a supporter for tendonitis, or a wrist supporter during exercise such as tennis or golf.

Conventionally, various types of supporters or braces for wrist joints have been reported and have been put to practical use, but all of them support the ankle of the wrist (ulnar pedicle process) when worn. It was a natural assumption.
On the other hand, the wrist joint has dorsiflexion, palm flexion, buckling, crookedness, rotation, and its movable direction in all directions, and its movable region is also quite wide.
However, as described above, since the conventional supporters are attached so as to cover the wrist ankle, the movement of the wrist joint is likely to cause a shift in the arm side direction, and the entire supporter often has an ankle on the wrist. There was a problem of getting over.

In order to prevent this displacement, it is conceivable to tighten the supporter or the brace strongly (see, for example, Patent Document 1), but excessive compression may cause a blood circulation disorder, and also covers all from the middle hand part to the forearm part. If this happens, there is a problem that the movement of the wrist joint is obstructed and it becomes difficult to play golf and tennis and even daily life.

  The present invention has been made in view of the conventional problems as described above, and ensures that the wrist joint is movable enough not to interfere with golf or tennis play or daily life, and no slippage occurs when worn. It is an object to provide a wrist joint supporter.

  As a result of various studies to solve the above-mentioned problems, the present inventor has found that an excellent result can be obtained by covering and attaching except for the ankle portion of the wrist, and the present invention has been completed.

  That is, the present invention provides a wrist joint supporter in which a portion corresponding to an ankle of the wrist of a supporter body having at least a wrist back surface covering portion and a wrist palm surface covering portion is provided with an excision portion that exposes the ankle without covering it. This solves the above problem.

  By using the wrist joint supporter of the present invention, it is possible to fix the wrist joint part while securing the mobility of the wrist joint so as not to interfere with daily life, and the wrist ankle is removed without being covered when worn. Therefore, even when the supporter tries to shift in the arm side direction during movement of the wrist joint, the exposed wrist ankle becomes an obstacle, and the shift movement is prevented.

  Therefore, the wrist joint supporter of the present invention is particularly suitably used as a supporter for ganglion compression, a supporter for tendonitis, or a supporter for wrist stabilization during exercise such as tennis or golf.

  In the present invention, the excision part may be formed in the support body in the shape of a hole, but the support body is excessively wide if it is formed in the shape of a concave bay at the edge in the arm side direction of the support body. This is more desirable because it can ensure the mobility of the wrist joint. In this case, it is more advantageous for the support body to prevent the ankle from climbing over the concave bay-shaped cutout portion so as to surround the ankle of the wrist about a half circumference. In addition, as a concrete shape of a concave bay shape here, a square bay and an arc bay are not ask | required. In addition, the back end surface of the concave bay-shaped cut-out part is an inclined surface that gradually becomes thinner upward, improving the adhesion with the ankle of the wrist and preventing displacement movement more effectively. This is desirable.

  In addition, if a cut is provided at the edge of the excision part of the supporter body from the cut part toward the finger side, even if the maximum dorsiflexion of the wrist joint is forced, It is more desirable because the supporter body can be prevented from getting over the wrist ankle. In general, the length of the cut is preferably 3 to 5 mm.

  In the present invention, the supporter body has a shape in which the side edge in the arm side direction of the wrist back side covering portion and the side edge portion in the arm side direction of the wrist palm surface side covering portion are in a straight line, and the wrist palm surface side covering In order to make the wrist flexion smoother, the finger edge side edge of the wrist part is set back in the arm side direction from the finger side edge part of the wrist back side cover. desirable.

  In this case, the width of the wrist back side covering portion is preferably a width that can cover from the second to the fifth metacarpal base to the lower end of both forearms, and the width of the wrist palm surface side covering portion is A width that can cover from the carpal bone to the lower ends of both forearm bones is preferable. The specific width dimension of the wrist back side covering portion is usually 4 to 6 cm, although there are individual differences. Similarly, the specific width dimension of the wrist palm surface side covering portion is the wrist back side covering portion. It is preferable that the width is usually 0.5 to 1.5 cm, particularly 1 cm narrower than the width of the part.

  Further, in the present invention, the arm side direction edge of the wrist back side covering portion of the supporter main body and the arm side direction edge of the wrist palm surface side covering portion are not aligned, and the wrist back side covering portion If the edge in the arm side direction is configured to recede in the finger side direction from the edge in the arm side direction of the wrist palm surface side covering portion, it is possible to make the wrist dorsiflexion smooth and more desirable. .

  In this case, the width of the wrist back side covering portion is preferably a width that can cover from the base portion of the second to fifth metacarpal bones to the lower edge of the radius, and there are individual differences in specific width dimensions. However, usually 2.5 to 5.5 cm, particularly 3 to 5 cm is preferable.

  In the present invention, the support body is not limited to a cylindrical body or a belt-like body, but is preferably a belt-like body, particularly a belt-like body made of a non-stretchable material, in order to obtain a stronger fixing force. In this case, it is more desirable to attach a fixing belt provided with, for example, a hook-and-loop fastener to the outer surface of the belt-like body in order to obtain mounting operability and a strong fixing action.

  The present invention will be further described below with reference to the drawings showing examples.

FIG. 1 is a schematic plan view showing a first embodiment of the wrist joint supporter of the present invention.
In FIG. 1, reference numeral 10 denotes a support body, which is composed of a belt-like body in which a wrist back side covering portion 11 and a wrist palm surface side covering portion 12 are coupled. The wrist palm surface side covering portion 12 has a length that covers not only the wrist palm surface when worn but also covers the wrist back surface by winding.

  Reference numeral 13 denotes an excision portion, which is formed in a square bay shape at the side edge of the supporter body 10 corresponding to the ankle of the wrist, and is exposed without covering the ankle when worn. The shift action of the support body 10 is prevented by the locking action of the edge of the cut portion 13 and the ankle of the exposed wrist. Further, as shown in FIG. 2, the end face of the rear side region of approximately ½ of the cut portion 13 becomes an inclined surface S that gradually becomes thinner toward the top, and the close contact with the ankle of the wrist is enhanced. Thus, the displacement is prevented more effectively.

  13a is a cut and is provided at the innermost edge of the cut portion 13 from the cut portion 13 toward the finger side. Even when the wrist joint is maximally dorsiflexed, the support body is expanded by the expanding action of the cut 13a. 10 will not get over the wrist ankle.

  The side edge portion 11b of the wrist back side covering portion 11 in the arm side direction and the side edge portion 12b of the wrist palm surface side covering portion 12 in the arm side direction are in a straight line, and the finger side direction of the wrist palm surface side covering portion 12 The side edge portion 12 a is slightly retracted in the arm side direction from the finger side side edge portion 11 a of the wrist back side covering portion 11. In other words, the width of the wrist palm surface side covering portion 12 is slightly narrower than the width of the wrist back side covering portion 11, whereby the wrist can be bent more smoothly.

  The finger outer surface side covering portion 11 has a width that can cover from the base portions of the second to fifth metacarpal bones to the lower end portions of both forearms, and the wrist palm surface side covering portion 12 extends from the carpal bones to both forearm bones. It has a width that can cover up to the lower end portion, and this allows the wrist joint portion to be fixed while maintaining the mobility of the wrist joint that does not interfere with daily life.
