Description

  The present invention relates to a joint support stay and a method of manufacturing the same.

  In the case of various diseases in joint sites, such as osteoarthritis, rheumatoid arthritis, tendonitis, etc., joint supporters are generally used in order to relieve the pain or prevent its occurrence.

  Thus, as an example of such a joint supporter, a thumb supporter for a hand is given. As shown in FIG. 7, conventionally, as shown in FIG. 7, a cylindrical part a for inserting and fixing a thumb and a lower thumb abductor tendon are provided. And the covering part b for the short thumb extension muscle tendon part are integrally coupled with the supporter fabric, and the attachment belt c is already attached. However, even if a supporter fabric having a strong stretching force is used, a sufficient holding and fixing action cannot be obtained with the fabric alone.

  Therefore, there is a commercially available support with a plate-like stay attached to the supporter as described above. However, when the plate-like stay is flexible, a satisfactory holding and fixing action is not yet obtained, and the other plate-like stay is not obtained. When is hard, there is a problem that the movement of the thumb is strongly restricted.

  In addition, a product in which the cylindrical part a and the covering part b are integrally molded with a synthetic resin instead of a supporter cloth is already on the market, but because of the integral molded body, the size is fixed and lacks fit. There was a problem.

  The present invention has been made in view of the conventional situation and problems as described above. In addition to obtaining a sufficient holding and fixing action, the joint has little trouble with the movement of the thumb and the like and has excellent fit. It is an object of the present invention to provide a stay for a joint supporter that can obtain a supporter.

Joint supporter stay according to the present invention, flexible and have a, and by brought one another twist joining straight lower portions of the open both outer edges of the horseshoe shape of the synthetic resin flat plate stay having viewed horseshoe shape Further, the present invention is characterized in that a cylindrical portion for inserting and fixing the thumb and a covering portion for the long thumb abductor tendon and the short thumb extension muscle tendon are provided .

A method of manufacturing a joint supporter stay according to the present invention, flexible and have a substantially horseshoe shape and a synthetic resin plate-stay with a plan view horseshoe shape, and slightly larger in cut to cover the stay, after forming the trimmed part over edging and allowed sandwiched between two supporters fabric, combined twist straight lower portions of both outer edges which is open of the horseshoe shapes, cylindrical thumb inserted and fixed And a covering portion for the long thumb abductor tendon portion and the short thumb extensor muscle tendon portion, and then the edge portion of the twisted portion between the lower portions of the outer edge portions is stitched.

  If a joint supporter is manufactured using the joint supporter of the present invention, the flexible horseshoe-shaped stays are twisted together at the lower part of both outer edges, so that it is suitable for insertion and fixing of thumbs and the like. The supporter is excellent in scooping fit and sufficient holding and fixing action due to the torsional action and flexibility of the stay, while the movement of the thumb etc. is not so difficult. Absent.

  FIGS. 1 to 3 show an example of a stay of the present invention suitable as a stay for a thumb supporter, which will be described below with reference to FIG.

  10 is a horseshoe-shaped flat stay, and any material can be used as long as it has flexibility. For example, a synthetic resin such as polyethylene is preferably used. The thickness is also selected as appropriate, but usually 1 to 2 mm is sufficient. The specific method of forming such a horseshoe-shaped flat stay 10 is not particularly limited, but punching from a synthetic resin plate is simple.

  Since 11a and 11b form the three-dimensional stay 20 mentioned later by twisting this part mutually in the lower part of the outer edge of the flat plate stay 10a, both the parts 11a and 11b are linear with the same dimensions. This is desirable in terms of ease of twisting.

  Reference numeral 20 denotes a three-dimensional stay, and the flat plate stay 10 is twisted to each other at both outer edge lower portions 11a and 11b to thereby extend the cylindrical portion 20a for thumb insertion fixation, the long abductor abductor tendon portion, and the short thumb extension. It is comprised from the coating | coated part 20b for muscle tendons.

  The twisted portions 11 of the outer edge lower portions 11a and 11b may be directly joined by an adhesive or an adhesive tape. However, as shown in the embodiments described later, the support portions are held between the support fabrics and stitched at the edge portions. Such an indirect joining is advantageous in that it provides a better fit and makes the thumb move more smoothly. In addition, as a supporter fabric, it does not matter whether it is a stretchable fabric or a non-stretchable fabric.

  Thus, the joint support stay according to the present invention has the three-dimensional stay 20 as the main feature as described above, and can be widely applied not only to the thumb supporter of the hand but also to the supporter attached to other joint parts. Can do.

Example A method of manufacturing the stay of the present invention used for the thumb supporter of the hand will be described with reference to FIG.
First, a horseshoe-shaped flat plate stay 10 having flexibility, and two supporter fabrics 30 that are substantially the same shape as the flat plate stay 10 and are cut with a slightly larger dimension (see FIG. 4 (1)). . In addition, 31 is a fastening piece and is integrally formed on the upper side of the supporter fabric 30 at the time of cutting.

Next, as shown in FIG. 4 (1), after the flat plate stay 10 is placed on the first supporter fabric 30a, the second supporter fabric 30b is further stacked as shown in FIG. 10 was sandwiched between two supporter fabrics 30a and 30b.
Next, as shown in FIG. 4 (3), the two supporter fabrics 30 a and 30 b were edged in the holding state to form an edge portion 32.

  Next, the lower portions of both outer edges are twisted together, and the edge portions 32a and 32b are stitched together to form a stitched portion 33. As shown in FIG. 4 (4), the tubular portion 40a for inserting and fixing the thumb and the long thumb abduction The suture solid stay 40 of the present invention in which the covering portion 40b for the muscle tendon portion and the short thumb extension muscle tendon portion was integrally formed was manufactured. Incidentally, a solid stay 20 as shown in FIG. 2 exists inside the stitched solid stay 40. In addition, a hook-and-loop fastener (not shown) is attached to the fastening piece 31 and the tubular portion 40a so that the fastening piece 31 is freely removable.

Application Example FIG. 5 shows an example of a thumb supporter provided with the stay of the present invention. A mounting belt 40c for winding and fixing to the wrist is attached to the covering portion 40b of the suture solid stay 40 manufactured in the embodiment. It is configured. In addition, 41 is a hook-and-loop surface fastener, and 42 is a belt loop. Thus, such a thumb supporter for the hand is mounted and used at the thumb joint of the hand as shown in FIG.
