Description

Detailed Description of the Invention (Industrial Field of Application) The present invention is characterized in that the big toe is placed outward (on the adjacent second toe side).
This invention relates to a supporter for correcting a big toe valgus that is bent and deformed so as to return it to its normal state.

(Prior art) As shown in Fig. 4, the big toe valgus is a deformation in which the big toe 1 remains bent toward the second toe 2 (outward). The first phalanx 3 is bent and deformed toward the second toe 2, and as a result, the first metatarsal phalanx 4 opens inward (to the side opposite to the second toe 2), and the first metatarsal phalanx 5 moves inward. It slips out.

The big toe is everted (curved outward and deformed)
The main cause is that recently, we have not had the opportunity to directly walk on hard ground such as dirt or stones, and since we were born we have been wearing soft-soled shoes, so there is no need to use the thumb anymore, and the thumb gradually degenerates. It is believed that it bends when pushed outward. Another cause is narrow width,
Because they wear pointy shoes that tend to hurt the toes, they are said to tighten the feet and bend the big toes outward.

When this happens, not only does the first metatarsal joint 5 of the big toe 1 cause pain on the sole of the foot, but the walking strength of the foot becomes poor and the balance of the foot becomes unstable, leading to falls and injuries. It becomes easier to do.

In order to correct this valgus big toe, conventionally, as shown in FIG. A fixing band 6 for tightening and fixing the joint 5, a thumb wrapping band 7 connected to the fixing band 6 and wrapping around the thumb 1, and a second thumb wrapping band 7 inside the thumb wrapping band 7.
A velvet fastener band 8 has one end attached with a velvet fastener on the side (on the opposite side of the finger), and a velvet fastener band 8 with a velvet fastener attached to the fixed band 6 at the other end so that the thumb 1 opens inward. It was starting to open towards the side.

In addition, as shown in Japanese Utility Model Publication No. 60-144414, one end of two elastic belts is fixed to the bag part placed over the big toe, and one belt is stretched diagonally across the surface of the foot. Wrap the first half of the belt, bring it back to the front, and secure it to the surface of the foot with a hook-and-loop fastener.Turn the other belt from the back of the foot to the front, wrap the second half of the leg, and use the hook-and-loop fastener to secure the belt to the appropriate position. Hallux valgus braces that are fixed to the body are known.

Further, as shown in Japanese Utility Model Application Publication No. 60-71213, a band body made of stretchable fabric and having a substantially truncated conical shape, and a band body extending obliquely from the proximal edge of the large diameter side of the band body. It consists of a band-shaped fixing belt with a locking part at the tip, and is characterized by having a sole support part that can accommodate a flexible patch plate on the inner peripheral surface of the band body on the opposite side of the fixing belt. Foot adjustment retention bands are also known.

(Problems to be Solved by the Invention) In the above-mentioned prior art, in the first example, the first metatarsal joint (hereinafter referred to as the first joint) 5 of the valgus big toe is held in the normal position by the fixation band 6. Although it is commendable in that it can be fixed, since only the velvet fastener band 8 is used to open the valgus thumb 1 inward, the tension is weak and it is unstable (displacement). Furthermore, in order to wrap the two places with one unfolded thick cloth,
It requires skill to attach it to the foot, and the separate velvet fastener band 8 is easily dusted off. Furthermore, this supporter tends to fall off from the tip of the foot when it is attached to the foot for a long time or when taking off the shoe. If they were made of rubber cloth to prevent them from falling off, there was a problem in that they were too thick to be worn with shoes.

In the second case, the hallux is pulled and valgus as shown by the arrow in Figure 6, and the hallux valgus cannot be recovered and maintained on the extension line of the first metatarsal bone (normal position), causing the hallux valgus to progress further. There is a problem that this is particularly dangerous for people with long big toes, and there is a strong possibility that the cushioning member 6 will be compressed and the pain will increase when the shoes are worn for a long time.

In case 3, the bag is not covering the big toe, so case 7
As shown by the dotted line in the figure, there was a problem in that the force to hold the hallux in the normal position was extremely weak, making it difficult to recover from the bunion.

(Means for Solving the Problems) The present invention aims to solve the above problems, and includes a joint fixation band having a width and length that can wrap around the entire first metatarsal joint of the toe. a big toe enveloping part connected to the joint fixation band and capable of enveloping the big toe; one end fixed to the outer side surface of the big toe enclosing part; A tensioning band that is wound around the hook and has a length that reaches any point on the outer surface of the joint fixation band through the other side of the joint fixation band, and is fixed to the outer surface of the joint fixation band. , a part where the pulling band contacts the lower part of one side of the joint fixing band, and a part where the end part contacts the joint fixing band, which can be freely attached to and detached from both the pulling band and the joint fixing band. It is characterized by the attachment of adhesive tape.

Hereinafter, the present invention will be specifically explained with reference to embodiments illustrated in the drawings. In Fig. 1, reference numeral 11 denotes a joint fixation band made of cloth that is wrapped around the first joint of the other four fingers in order to fix the first joint of the thumb in its normal position. It is pasted and the winding terminal 1
Also attached to la is a mating velvet fastener which can be fixed to the velvet fastener on the outer surface. Reference numeral 12 denotes a cloth thumb encasing part that is connected to the joint fixation band 11 and can completely enclose the thumb; 13, one end 13a of which is fixed to the outer side surface of the thumb encasing part 12; A tensioning band made of cloth having a length that extends from the foot through one outer side of the foot, wraps around the foot, and reaches the joint fixation band 11 through the other outer side. 13 is the joint fixation band 11. The part 13b that comes into contact with the lower part of one side of the joint fixation band 11 and the end part 13c are the joint fixation band 11.
Velvet fasteners are attached to both the tension band 13 and the joint fixation band 11 in the portions that come into contact with the joint.

When in use, first place the thumb encasement 12 completely over the big toe 1 of a bare foot or a socked foot, then wrap it tightly together with the first joints of the other four toes with the joint fixation band 11, and then Tighten so that one joint is in the normal position and fix the winding end 11a to the velvet fastener on the outer surface. Next, while pulling the pulling band 13 so that the valgus thumb opens inward, first pull the 13b part of the joint fixing band 1
Fix a velvet fastener to 1, hook it to 14, turn it, and attach the other end 13c to joint fixation band 11.
Fix the velvet fastener at the best suitable location. The attached state is as shown in Figures 2 and 3, and is compatible with either the left or right foot.

(Effects) The present invention provides a joint fixation band that has a width and length that can wrap around the entire first metatarsal joint of a toe, and a joint fixation band that is connected to the joint fixation band and that wraps around the big toe. one end is fixed to the lateral side of the thumb accommodating part, and the joint is fixed by wrapping the thumb from the fixing point through one lateral side of the foot, passing through the other lateral side, and fixing the joint. The joint fixation band has a length that can reach any point on the outer surface of the joint fixation band, and the tension band is fixed to the outer surface of the joint fixation band, and the tension band is in contact with the lower part of one side of the joint fixation band. Since a fixing tape that can be freely attached and detached is attached to both the tension band and the joint fixation band in the part where they touch and the part whose end abuts on the joint fixation band, (1) the joint fixation band 11 can be used Anti-thumb 1st
With the joint fixed in the normal position, the pulling band 13 applies a pulling force from the most efficient direction to bend the valgus thumb back inward, making normal correction only possible. The correction effect is greatly improved.

(2) Joint fixation band 1 of tension band 13
The fixing points on 1 are 2 of 13b and 13c.
This allows the valgus big toe to be corrected and maintained in the normal position, on the extension line of the first metatarsal bone as shown by the dotted line in Figure 7, and has a significant immobilizing effect when weight is lifted during walking. The firmness and fixation are extremely stable and reliable, and can withstand long-term use.

In addition, the fixation location of the terminal 13c of the tension band 13 on the joint fixation band 11 can be selected at the most convenient arbitrary position, and
Fixation becomes easier.

(3) Since the material of the supporter is a soft material made by laminating velvet fasteners on cloth, it can be attached over socks and can also be worn with shoes.

(4) Installation is easy and requires no skill. Moreover, since the structure is simple, it can be provided at low cost.
