Description

SUPPORT STRUCTURE FOR PREVENTING OR TREATING DISEASE ASSOCIATED WITH DEFORMITY OF FOOT}

The present invention relates to a support structure for preventing or treating a disease associated with foot deformation. Specifically, the present invention includes a foot portion covering the foot of the front foot, a foot portion covering the bottom of the forefoot, and at least one pair of non-slip means for holding the inner and outer sides of the forefoot, wherein the foot portion and the sole portion are connected together. When the support structure is worn on the foot, the boundary between the instep and the sole of the foot is aligned with the inner and outer sides of the forefoot, and the non-slip means for catching the inner and outer sides of the forefoot is the cylindrical structure. In each part which comes into contact with the inner and outer sides of the forefoot is attached to the inner surface of the cylindrical structure, the instep portion has a greater elongation than the sole part when measured in a direction corresponding to the width direction of the foot on which the support structure is worn Having a support structure for preventing or treating a disease associated with foot deformation. The use of such a support structure of the present invention not only maintains the transverse arch formed by wearing the support structure on the foot even when the user's weight is loaded, but also suppresses the clothing pressure applied to the instep by the support structure to a relatively low level. This can prevent the occurrence of edema and paralysis. Accordingly, the present invention does not cause discomfort and pain to the user, but is caused by the deterioration of the arch of the foot due to foot deformation (flat foot, valgus valgus, posterior tibial tendon dysfunction (hereinafter often abbreviated as "PTTD")) It allows for comprehensive and effective prevention and treatment of various diseases associated with peace) and heel valgus). In addition, the above-described superior effects of the present invention can be obtained by using a thin material and a simple structure, so that the support structure of the present invention can be easily worn on the foot and can also be used with outdoor and indoor foot wear. . This means that the present support structure is easy to use on a daily basis and therefore the excellent prophylactic and therapeutic effects of the present invention described above can be easily improved to a large extent with the daily use of the support structure.

The human foot has three arches, ie a transverse arch that connects the base of the first toe (ie, the big toe or the big toe) with the base of the fifth toe (ie, the small toe or the young toe), the heel and the big toe. Medial longitudinal arches connecting the base of the lateral and lateral longitudinal arches connecting the base of the heel and toe. The arch of the foot acts as a spring while moving with the weight carried on the foot, and therefore the arch is important for alleviating and absorbing shocks from the ground and maintaining body balance. In particular, the transverse arch is like a spring consisting of the metatarsal ligaments and muscles, and it is important to disperse the impact on the tip of the toes while walking and to balance the whole body. But nowadays, the number of flat people is increasing due to the collapse of the transverse arch. Specifically, the flat foot is a state in which the lateral arch collapses (ie, flattened), and the foot spreads in a fan shape when viewed from above. This condition is caused, for example, by weakening of the muscles due to lack of exercise and weight gain and relaxation of the metatarsal ligaments caused by the use of high-heeled shoes. Symptoms of flat foot include pain caused by contact between the inner surface of the shoe and the bases of the first and fifth toes. Especially flat feet occur in women who wear long, high-heeled shoes for a long time, and in many cases flat feet cause big toe valgus, ie the first toe bends from his base to the second toe and also the joint at the base of the first toe It is fixed while protruding outward from the inner side of the foot. Flatfoot and toeval valgus cause pain as well as unnatural walking posture, causing back pain and fatigue throughout the body.

In addition, for the tibial tendon having a function of maintaining the arch of the foot, foot deformation may be caused by tendon dysfunction due to aging or the like. This dysfunction of the tibial tendon is called "PTTD", and has attracted attention as a cause of various foot deformations such as heel valgus and flat foot.

Noting the importance of foot arches, various socks and supports have been developed to improve athletic performance. Patent Document 1 discloses a pair of socks each having a continuous high elastic portion and a separate low elastic portion, wherein the continuous high elastic portion has a portion of the socks corresponding to the area across the sole arch and the area across the upper part of the calcaneus. And the separate low elastic portion comprises the rest of the sock. This sock can raise the sole arch of the foot without causing excessive tightening of the instep, thus reducing fatigue and improving the user's athletic performance by correcting the longitudinal arch. However, Patent Document 1 does not describe the transverse arch and its importance.

Patent document 2 also discloses a sock for smooth foot movement during walking. The socks are manufactured by changing the design and material of the knitting according to the position of the socks so that the angle between the longitudinal axis of the sole and the transverse axis of the toe is greater than 0 ° and less than 80 °. In addition, the instep portion of the sock is made of a material in which the elongation in the direction corresponding to the longitudinal direction of the foot on which the sock is worn decreases. Patent Document 2 describes, in particular, the use of a locking area surrounding each part of the sock that is opposed to the metatarsal and / or metatarsal joints of the foot on which the sock is worn. This locking area prevents the development of the big toe valgus by appropriately compressing the metatarsal and / or metatarsal joints to spread the toes of the user. However, this patent document does not describe the recovery of the transverse arch or the improvement of flat foot.

Various supports and socks have been proposed to tighten the metatarsal ligaments and restore the transverse arch to correct flatfoot and valgus valgus. For example, Patent Document 3 discloses a support for correcting the big toe valgus, which supports a hole in each portion of the support that is opposed to a joint at the base of the large toe and the small toe of the foot on which the support is worn. Perforated openings, conical cushions protruding from the point of the foot that faces the meridian point called the "yongcheon" of the foot, and a cylindrical joint wrap that covers the entire metatarsal bone and wraps around the soles of the foot and the foot to achieve compression and acupressure effects. And a pad that is individually fitted between the large toe and the second toe and between the small toe and the fourth toe to correct the transverse arch by applying a corrective force in the opposite direction of the compression force. Since the support of Patent Document 3 has a structure covering all metatarsal bones and compressing the metatarsal ligaments, the compressive force applied from the inner and outer ends of the metatarsal ligaments toward the center of the foot facilitates the formation of the transverse arch. At the same time, however, the support exerts a tightening force on the metatarsal ligament in the direction from the instep to the sole, which may lead to the collapse of the transverse arch. In particular, when the user's weight is not carried on the foot, the effect of the pad is reduced and arch formation is not satisfactory. In addition, the use of this support is accompanied by the risk of edema and paralysis due to particularly strong tightening of the instep.

Patent Document 4 discloses a support having a toe receptacle and an adjustment belt, wherein the large toe and the small toe of the foot are fitted to the toe receptacle, respectively, and the extent of outward spreading of the large toe and the small toe is the big toe valgus and the little toe. The adjustment belt is adjusted based on each symptom of the varus. This support is intended for use with fashionable shoes such as pumps. Thus, in order to obtain a design suitable for this purpose, the instep of this support is designed with a thin line extending along the base of the toe. The support of Patent Document 4 does not cause collapse of the transverse arch because it does not tighten the metatarsal ligament in the direction from the instep to the sole of the foot, but this support is tightened from the inside and outside of the metatarsal ligament in the direction toward the center of the foot (this force is the transverse arch). It is not necessary to have a structure to apply). Therefore, this support is not suitable for improving flatfoot.

Patent document 5 discloses a pair of functional socks for recovering collapsed transverse arches. The sock is made of a high elastic material in the sole covering the metatarsal ligament of the sole and the inner and outer portions of the sole of the sole, while the instep portion of the sock covering the metatarsal ligament of the instep has a lower elasticity than the high elastic material. Has a structure made of. According to the description of Patent Document 5, when the functional socks are worn, the feet are tightened in their width direction so that the inner and outer ends of each calcaneal ligament are pulled closer to each other, while the feet are in the thickness direction from the instep to the sole of the foot. By not tightening, the metatarsal ligaments effectively recover to the desired transverse arch form. According to a particular embodiment of the functional socks disclosed in Patent Document 5, the low elastic material is a cotton used to make a conventional sock, and the high elastic material is a cotton material on which urethane rubber is woven. The cotton material containing urethane rubber cannot exert the tightening force necessary to support the force point of the elastic region, and the cotton for socks used as the low elastic material is stretched together with the high elastic region of the socks. Thus, when the inventors re-manufactured and tested the socks of Patent Document 5, the socks showed a slight effect of forming a small lateral arch before weight was put on the foot, but the lateral arch forming effect was obtained when the weight was loaded on the foot. Lost.

In addition, as a therapeutic guard for the "PTTD", a shoe insert (so-called "UCBL shoe insert") developed by the University of California Biomechanics Laboratory (UCBL) is known. This UCBL shoe insert is made of a rigid plastic material (such as polyurethane) and includes an inner and outer longitudinal arch support and a heel with depressions that hold the calcaneus at an appropriate height. The shoe insert is used to be fixed to the shoe by a belt or the like. UCBL shoe inserts are made of hard material and cover a large area of the foot, giving the user restraint and discomfort. In general, UCBL shoe inserts are custom made in molding using molds having cavities with a negative image of each patient's foot, which is disadvantageous in that the manufacturing is laborious and expensive.

Guards such as those manufactured and sold under the trade name "Aircast" (one of its specific examples being "AirLift" (registered trademark)) are known, which cover not only the sole but also the entire ankle part. The sole of the guard is provided with a metatarsal pad in the form of an air pump through which air can be blown. However, such guards have the problem of pressing the entire ankle portion of the foot and causing poor blood circulation and pain and discomfort to the user.

Richie Brace, Inc. "Richie Brace" (registered trademark), which is manufactured and sold by, is also known. This protector has a structure that strongly restricts the movement of the joints of the foot, except for instep flexion and sole flexion. In other words, the guard functions like a cast that holds the foot firmly, except for instep flexion and sole flexion. Since these guards are large and custom made, they are expensive and difficult to purchase.

In addition, all conventional guards for treating PTTD have little effect of preventing or correcting flat foot.

As is evident from the foregoing, a comprehensive and effective prevention of various diseases that can be used daily and is also associated with foot deformities such as flat feet, big toe valgus, deterioration of the arch of the foot due to PTT (flattening of the soles) and heel valgus. And no socks or supports to allow for treatment.

As described above, not only can the lateral arch formed by wearing the support on the foot even when the user's weight is loaded, but also does not cause discomfort and pain to the user, and deforms the foot (flat, toe valgus, PTTD) There has been a need for supports or socks that enable comprehensive and effective prevention and treatment of various diseases associated with deterioration of the foot arch (flattening of the sole) and heel valgus).

In this situation, the inventors have conducted extensive and in-depth studies to solve the above problem. As a result, the present invention includes an instep portion covering the instep of the forefoot, a sole covering the bottom of the forefoot, and at least one pair of non-slip means for holding the inner and outer sides of the forefoot, wherein the instep and the sole are connected together to form a cylindrical shape. When the support structure is worn on the foot, the boundary between the instep and the sole of the foot is aligned with the inner and outer sides of the forefoot, and the at least one pair of non-slip means for catching the inner and outer sides of the forefoot The cylindrical structure is attached to the inner surface of the cylindrical structure at each part in contact with the inner and outer sides of the forefoot, and the instep is larger than the sole when measured in a direction corresponding to the width direction of the foot on which the support structure is worn. It was unexpectedly found that a support structure having an elongation could solve this problem. In addition, noting that there is a correlation between the various diseases involved in foot deformation (flat feet, valgus valgus, lowering of the arch of the foot due to PTTD (flattening of the paw) and heel valgus), the inventors We found the same thing: by adding an ankle support band worn around the ankle around the ankle and surrounding the ankle to the support structure, it was possible to correct the three-dimensional structure of the entire foot from front to back. The prophylactic and therapeutic effect of the support structure is improved. The ankle support band includes a front ankle portion and a heel portion covering the front part of the ankle, wherein the front ankle portion and the heel portion, when the ankle support band is worn around the ankle, between the front ankle portion and the heel portion The boundary is connected together to align with the inside and outside of the ankle, and the ankle support band further comprises at least a pair of anti-slip means for holding the ankle, the anti-slip means being attached to the inner surface of the ankle support band, One of these non-slip means is attached to the portion of the ankle support band that is in contact with the internal body of the foot, and the other of the non-slip means is provided at the portion of the ankle support band that is in contact with the foot in the intermediate position between the foot's surgery and the heel. Attached. In addition, the present invention is a flexible toe toe valgus flexible plate attached to the inner surface of the sole, extending along the portion in contact with the edge of the medial portion of the forefoot in the support structure, the thickness is continuously reduced from the top to the bottom It was found that the support structure includes the flexible toe valgus correction flexible plate having a wedge-shaped cross section, thereby effectively preventing and correcting the rotation of the big toe phalanx, which is the cause of the big toe valgus. The present invention has been completed based on this finding.

The foregoing and other objects, features and advantages of the present invention will become apparent from the following detailed description and claims in conjunction with the accompanying drawings.

By using the support structure of the present invention, not only can the lateral arch formed by wearing the support structure on the foot even when the user's weight is loaded, but also the garment pressure applied to the instep by the support structure can be suppressed to a relatively low level. The occurrence of edema and paralysis can be prevented. Accordingly, the present invention provides a comprehensive and comprehensive range of diseases that are accompanied by foot deformity (flat, big toe valgus, lowering of the arch of the foot due to PTTD (flattening of the sole) and heel valgus) without causing discomfort and pain to the user). Enable effective prevention and treatment. In addition, the above-described superior effects of the present invention can be obtained by using a thin material and a simple structure, so that the support structure of the present invention can be easily worn on the foot and can also be used with outdoor and indoor foot wear. .

Hereinafter, the present invention will be described in detail.

The normal foot shown in FIG. 1A has a transverse arch (indicated by broken lines) connecting the base of the first toe (head of the first metatarsal bone) and the base of the fifth toe (head of the fifth metatarsal bone). On the other hand, the flat foot shown in FIG. 1B collapses and shows symptoms of a flat transverse arch.

The support structure of the present invention is used to correct flatfoot by restoring the collapsed transverse arch shown in FIG. 1B to the normal transverse arch shown in FIG. 1A.

In the present invention, the term "support structure" means a foot brace having a structure of a support, and not only the support itself, but also other foot braces, such as in the form of socks or stockings, as long as they have the structure defined in the present invention. It is to include. In addition, in the present invention, the "side" of the foot does not mean only the inner and outer sides of the foot, but also means both sides of the instep of the foot.

2 is a perspective view of one embodiment of the support structure of the present invention worn on a flat foot. 3 is a cross-sectional view of the foot of FIG. 2, taken along the line Ι-Ι of FIG. 2.

The support structure of the present invention shown in FIG. 2 has the shape of a support. The support 6 in FIG. 2 has an instep 7 covering the instep of the forefoot (ie the top of the forefoot) and a sole 8 covering the bottom of the forefoot (ie the bottom of the forefoot). 7) and the sole 8 are connected together to form a cylindrical structure, so that when the support structure is worn on the foot, the boundary between the instep 7 and the sole 8 is aligned with the inner and outer sides of the forefoot. The instep portion 7 has a greater elongation than the sole portion 8 when measured in a direction corresponding to the width direction of the foot on which the support structure is worn. Further, at least one pair of anti-slip means 9, 9 (shown in broken lines) for holding the inner and outer portions of the forefoot are attached to the inner surface of the cylindrical structure at each part in contact with the inner and outer portions of the forefoot in the cylindrical structure. have. When the support 6 is worn on the foot, the non-slip means 9, 9 for holding the inside and the outside of the forefoot are supported by the support (with reference to Fig. 3) in the state where the sole 7 tightens the foot in its width direction (see Fig. 3). 6) to fix the inside and outside of the foot to the foot. In the support structure of the present invention, as described above, the elongation of the instep portion 7 is greater than the elongation of the sole 8 when measured in the direction corresponding to the width direction of the foot on which the support structure is worn. With this structure, the garment pressure applied to the instep is reduced, and the tightening force that forms the transverse arch while acting in the width direction of the foot is effectively applied to the foot. In addition, by using the non-slip means 9 and 9 for holding the inner and outer sides of the forefoot, not only the tightening force can be effectively obtained, but also the tightening force can be maintained while the weight is carried on the foot. On the other hand, a support such as that disclosed in Patent Document 5 having no anti-slip means for holding the inner and outer sides of the forefoot becomes larger than the elongation of the sole 8 when the elongation of the instep 7 is measured in the width direction of the foot. Even when present, they slide off the inside and outside of the foot. As a result, the tightening force exerted on the sole is balanced with the tightening force exerted on the instep so that the desired transverse arch correction is not achieved.

There is no particular limitation on the materials for these instep and soles as long as the above-mentioned relationship between the elongation of the instep 7 and the elongation of the sole 8 can be satisfied, and there is no particular limitation in the manufacture of supports, stockings and socks. It can select from the material used suitably. In order to improve comfort during the use of the support structure of the present invention, it is desirable to use a material having breathability, hygroscopicity and quick drying. Specific examples of the material for the instep portion 7 and the sole portion 8 include the materials described in Patent Documents 1 and 2 above. These patent documents also describe methods for making different elongation areas in socks and the like, which methods can be applied to the present invention for controlling the elongation rate. Typical examples of the materials used are mixed fabrics of polyurethane and nylon. Since the sole 8 can be made of a material which is substantially inelastic, a nonwoven fabric of polypropylene or the like can also be used in the present invention.

As for the material for forming the anti-slip means 9 for holding the inner and outer sides of the forefoot, when the support structure of the present invention is worn on the foot, the material can fix the support structure to the forefoot at the inner and outer sides of the forefoot. There is no special limitation as long as there is. Materials and adhesives having a high coefficient of friction can be used to form the non-slip means 9 for catching the inside and the outside of the forefoot. Specific examples of materials with high coefficient of friction include synthetic rubbers such as ethylene-propylene-diene rubber (EPDM), chloroprene rubber (CR) and silicone rubber and natural rubber (NR).

No. 5,948,707 discloses water and vapor permeability with materials used to prevent slipping of casts (supports) used for legs and arms (eg, discontinuous elastomeric layers formed in polytetra-fluoroethylene films). Materials), which may also be used in the present invention. As for the adhesive, there is no particular limitation as long as it is appropriate to simultaneously realize satisfactory adhesion to the skin of the foot and also easy removal from the skin when the support structure is detached from the foot, and various conventional adhesives can be used. For example, a conventional double-sided adhesive tape can be used as the anti-slip means for holding the inside and the outside of the forefoot, and the support double-sided adhesive tape is replaced each time it is worn on the user's foot after removing the support structure. However, it is preferable to use an adhesive material in which adhesive strength is restored by washing. An adhesive material whose adhesive strength is restored by cleaning is an adhesive material which can be washed with water or a neutral detergent to restore the adhesive force when the adhesive force is lowered due to the adhesion of dust and oil during use of the adhesive material. Examples of such adhesive materials include a silicone gel adhesive layer described in JP-A-11-323616 and a urethane adhesive layer described in JP-A-2000-247061. Conventional adhesive elastic bandages can also be used.

The appropriate size of each of the instep 7 and the sole 8 of the support structure of the present invention varies with the size of the foot. It is desirable to select a suitable size so that satisfactory tightening force can be applied in the width direction of the foot and the garment pressure applied to the foot can be reduced. For example, with respect to the width of the support structure, the width of the sole may be about 1.0 to 1.5 times the width of the foot, and the width of the instep may be about 0.2 to 1.0 times the width of the foot because the instep is made of a material having a relatively high elasticity. have.

In the present invention, it is preferable that the support structure has an opening formed in a portion which comes into contact with the boundary between the metatarsal bone and the phalanx at the side of the foot (especially the medial part), for the following reason. In flat feet, the joints at the base of the first toe and the joints at the base of the fifth toe protrude outward from the medial and lateral sides of the foot, and even a slight increase in the thickness of the support or the socks increases friction and causes pain. . Also, in a foot with big toe valgus, swollen synovial sac or bunion can develop around the joint at the base of the first toe. In these cases, it is particularly desirable to form a bunion opening 10, 10 (shown in FIG. 2) at the portion that comes into contact with the joint to reduce friction between the support structure and the joint. There is no particular limitation on the size and shape of the bunion openings 10 and 10. For example, the bunion opening may be a circular or elliptical hole having a diameter or long axis of about 1.5-4 cm.

In the present invention, in order to obtain a satisfactory tightening force in the width direction of the foot and satisfactorily reduce the garment pressure applied to the instep, the elongation rate A of the instep part 7 is made larger than the elongation rate B of the sole part 8. (Ie, (A)> (B)), where each elongation is measured in a direction corresponding to the width direction of the foot on which the support structure is worn. The ratio (A) / (B) of the elongation rate (A) of the instep portion 7 to the elongation rate B of the sole portion 8 is preferably 1.2 or more, more preferably 2 to 200, and most preferably Is 2.5-100. Although the elongation B of the sole 8 may be 0%, in such a case, it is preferable that the elongation A of the instep 7 falls within the range mentioned below.

In the present invention, the elongation (A) of the instep 7 measured under a load of 4.9 N (500 gf) is generally 5 to 200%, preferably 35 to 180%, more preferably 75 to 155% The elongation (A) measured under a load of 17.7 N (1800 gf) is generally 10 to 300%, preferably 115 to 250%, more preferably 160 to 210%, and the elongation is It is measured in a direction corresponding to the width direction of the foot to be worn. When the elongation rate A of the instep 7 is smaller than the above range, the tightening of the instep becomes too strong (that is, the clothing pressure becomes too high), which may cause problems such as swelling, numbness, pain, and redness of the instep. . The elongation (B) of the sole 8 measured under a load of 4.9 N (500 gf) is generally 0 to 150%, preferably 1 to 100%, more preferably 5 to 75%, and 17.7 N The elongation (B) measured under a load of (1800 gf) is generally 0 to 180%, preferably 5 to 150%, more preferably 10 to 120%, and the elongation is the width of the foot on which the support structure is worn. It is measured in the direction corresponding to the direction. When the elongation B of the sole portion 8 is larger than the above range, the widthwise tightening force of the foot may become unsatisfactory. The elongation rates (A) and (B) were measured for an area having a length of 3 cm and a width of 2 cm.

Further, in order to form the instep portion 7 and the sole portion 8 of the support structure of the present invention, if a satisfactory tightening force can be obtained in the width direction of the foot and the garment pressure applied to the foot can be satisfactorily reduced, Combinations of different materials with elongation can be used. In particular, for the sole 8, in order to relieve the burden on the foot of the user, a material having a large elongation rate may be used for a portion where a strong tightening force is not required (for example, a portion far from the boundary between the metatarsal bone and the phalanx). Can be. Even in such a case, it is preferable that all of the elongation rates (A) and (B) and the ratio (A) / (B) are in the above ranges. The average of the elongation values for all parts of the instep 7 is used as the elongation rate (A), and the average of the elongation values for all the parts of the sole 8 is used as the elongation (B). It is preferable that the elongation rates (A) and (B) and the ratio (A) / (B) at least in the region around the boundary between the metatarsal bone and the phalanx be in the above ranges. Here, the "area around the boundary between the metatarsal bone and the phalanx" is 1 cm up and 1 cm down the border between the metatarsal bone and the phalanx, preferably 2 cm down and 2 cm above the border, more preferably up 3 cm. It is an area that is 3 cm down.

The ratio (A) / (B) used in the present invention may be a ratio of elongation measured under a load of 4.9 N (500 gf) or an elongation measured under a load of 17.7 N (1800 gf), among which One must be within the above range. More preferably both ratios are within each of the above ranges.

When the support structure of the present invention is worn on the foot, it is preferable that the garment pressure at the back of the foot is 0 to 25.0 kPa.

As for the shape and size of the anti-slip means 9 and 9 for holding the inner and outer sides of the forefoot, there is no particular limitation as long as the anti-slip means can fix the paper structure of the present invention to the forefoot at the inner and outer sides of the forefoot. For example, a non-slip means of a rectangular or pseudo rectangle having a length of 3 to 10 cm and a width of 0.5 to 3 cm is mentioned. Further, when the bunion openings 10 and 10 are formed as shown in Fig. 2, the anti-slip means may have a cutout that fits the opening. In addition, a plurality of non-slip means 9 can be attached to each part of the support structure which comes into contact with the inner and outer sides of the forefoot. For example, each part or one of the support structures which are brought into contact with the inner and outer sides of the forefoot may have two strips of anti-slip means 9 and 9 extending in the longitudinal direction of the foot, respectively, or side by side in a direction corresponding to the longitudinal direction of the foot. A number of square, round or elliptical anti-slip means 9, 9 arranged can be attached.

In the support structure of the present invention, the anti-slip means 9, 9 for holding the inner and outer portions of the forefoot are attached to each part of the supporting structure which comes into contact with the inner and outer edges of the foot and / or the inner and outer edges of the foot, and is non-slip The means may extend to the portion that comes into contact with the inner and outer edges of the sole.

In the present invention, before wearing the support structure on the foot, the non-slip means 9, 9 for holding the instep 7, the sole 8 and the inner and outer sides of the forefoot are shown, for example, with these components shown in FIG. 2. It can be stitched together in the shape of the support structure and combined together. Alternatively, the components can be combined together when the support structure is worn on the foot. For example, the support structure of the present invention uses an instep 7 and a foot 8 that can be combined with each other by a loop and a hook fastener, and anti-slip means 9 and 9 for holding the inside and outside of the forefoot. It can be formed by a method including the following steps (1) to (3) using a double-sided tape as a.

(1) A double-sided tape is attached to each edge of the inner and outer sides of the foot as anti-slip means for holding the inner and outer sides of the forefoot.

(2) Using the double-sided tape attached to each edge of the inner and outer sides of the foot, the sole of the foot provided with a hook fastener (attached to the outer surface of the sole of the foot at both edges of the sole of the foot) is fixed to the foot, At this time, the sole is fixed so that the foot is tightened in the width direction thereof.

(3) Attach the instep to the sole by hooking the loop fasteners provided on the instep (attached from the edges of both sides of the instep to the inner surface of the instep) to the corresponding hook fasteners of the sole (of course, the loop fastener It can be used on the sole and hook fasteners can be used on the instep).

A support structure having two or more bag parts (the back parts are described in Patent Document 5) in which the toes are located is one of the preferred embodiments of the present invention. The presence of such a back allows the user to pull the first and fifth toes towards the central axis of the sole to form a transverse arch when the user places the toes in each back to secure the support structure to the foot. Therefore, the non-slip means 9, 9 for holding the inner and outer portions of the forefoot can be easily fixed to the desired position of the inner and outer sides of the foot while maintaining the formed transverse arch.

In addition, the pad can be attached to the inner surface of the sole 8 at the portion opposite the metatarsal bone of the foot. This pad can improve the effectiveness of the support structure, which corrects the transverse arch, especially when weight is carried on the foot. For the material and the manufacture of the metatarsal pad, reference can be made to, for example, Patent Document 3.

Although the embodiment shown in FIG. 2 is the support itself, the support structure of the present invention may be in the form of socks or stockings. When the support structure of the present invention is in the form of socks or stockings, other parts other than the non-slip means 9 and 9 for holding the instep 7, the sole 8 and the inner and outer sides of the forefoot produce socks and stockings. It may be prepared by conventional materials and methods commonly used to.

4 is a perspective view of one embodiment of the support structure of the present invention in the form of a sock before it is worn on the foot, and FIG. 5 is a state worn on the foot in a perspective view of the support structure of FIG. In the support structure 6 'of the present invention in the form of both feet, other portions than the non-slip means 9 and 9 for holding the instep 7, the sole 8 and the inner and outer sides of the forefoot are as described above. The additional portions 11a and 11b can be made in a conventional manner using materials commonly used to make conventional socks or stockings.

6 shows a medial malleolus side in a perspective view of another embodiment of the support structure of the present invention in the form of a sock, and FIG. 7 shows a lateral malleolus side in a perspective view of the support structure of FIG. 6. The support structure 6 ′ of the embodiment shown in FIGS. 6, 7 further comprises an ankle support band, which is worn around the ankle, surrounding the ankle and the front of the ankle. The ankle support band has a front ankle part 12 covering the front part of the ankle and a heel part 13 covering the heel. The front ankle 12 and the heel 13 are connected together so that the boundary between the front ankle and the heel is aligned with the inside and outside of the ankle when the ankle support band is worn around the ankle. In addition, anti-slip means 14, 14 (shown by broken lines) for holding the ankle are attached to the inner surface of the ankle support band, one of which is the portion of the ankle support band that comes into contact with the internal body of the foot. And other non-slip means are attached to the portion of the ankle support band that comes into contact with the foot at an intermediate position between the foot's surgery and the heel. In addition, the ankle portion 12 has a greater elongation than the heel portion 13 when measured in the direction corresponding to the width direction of the foot on which the support structure is worn. With this structure, the ankle support band is effective in preventing and treating PTTD while preventing unnecessary pressure on the blood vessels and nerves in the ankle and without excessively obstructing the movement of muscles and ligaments around the ankle. As mentioned above, there are interrelationships between various diseases involving foot deformity (eg flatfoot, big toe valgus and PTTD), with the addition of the ankle support band to the support structure of the present invention, thereby providing a more comprehensive And effective prevention and correction are possible. In addition, as shown in FIG. 7, the metatarsal pad 15 can be attached to the inner surface of the sole 8 at the portion opposite the metatarsal bone of the foot. By attaching this metatarsal pad 15, the preventive and corrective effect of the present invention will be remarkably improved. Materials and methods for manufacturing the metatarsal pad 15 are as described above.

The ankle support band will be described in detail below. This ankle support band can be manufactured integrally with the support structure in the form of a sock. Alternatively, a separately prepared ankle support band may be attached to the body of the support structure. With respect to the shape and size of the ankle support band, there is no particular limitation as long as the support structure is worn on the foot so that the ankle support band can wrap around the front and heel of the ankle and can be held in the desired portion of the foot without slipping out. For example, a strip having a width (length in the longitudinal direction of the foot) of 1 to 8 cm, preferably 2 to 5 cm, can be used as the front ankle 12. The heel portion 13 preferably has a width (length in the longitudinal direction of the foot) sufficient to be firmly fixed to the heel. For example, the width of the heel portion 13 is preferably 5 to 12 cm, more preferably 6 to 10 cm. As shown in Figs. 6 and 7, the heel portion 13 preferably has a circular or elliptical opening formed in the portion which comes into contact with the center of the heel and the periphery of the center thereof.

The ankle 12 and heel 13 may be formed separately by the same materials and methods used to form the instep and sole. As in the case of the instep and the sole, the ankle 12 is greater than the elongation B 'of the heel 13 when measured in the direction corresponding to the width direction of the foot on which the support structure is worn. It is necessary to have (ie, (A ')> (B')). The ratio (A ') / (B') of the elongation rate (A ') of the ankle portion to the elongation rate (B') of the heel portion is 1.2 or more, preferably 2 to 200, and most preferably 2.5 to 100. . In addition, it is preferable that both the elongation rate A 'and the elongation rate B' are within the ranges described above in relation to the elongation rate A and elongation rate B described above. The elongation rate B 'of the heel portion 13 may be 0%, but in such a case, the elongation rate A' is preferably within the above range.

The non-slip means 14, 14 for catching the ankle may be formed of the same materials and methods used to form the non-slip means for catching the inside and outside of the forefoot. As described above, the anti-slip means 14 for holding the ankle on the inner side are attached to the portion of the support structure which comes into contact with the inner side of the foot. The position and size of the non-slip means 14 for holding the ankle on the internal side is preferably such that the non-slip means 14 completely cover the internal body when the support structure of the present invention is worn on the foot. On the other hand, the non-slip means 14 for holding the ankle on the surgical side are attached to the portion of the support structure which comes into contact with the intermediate position between the surgery and the heel of the foot. By arranging the non-slip means 14 and 14 for holding the ankle in the manner described above, it is possible to easily suppress the occurrence of the valgus (outward angulation of the foot) while preventing excessive suppression of the valgus (inward angulation of the foot). Therefore, effective prevention and treatment of PTTD is possible without excessively restricting foot movements. In addition, it is preferable that the anti-slip means 14 (for holding the ankle) are attached to the portion where the entire anti-slip means 14 are located below the surgical bottom (indicated by the dashed line in FIG. 7). Alternatively, the non-slip means 14 for holding the ankle may be attached to a portion that allows a portion of the non-slip means 14 to cover the lower part of the surgery. In this case, the area of the anti-slip means 14 in the part covering the lower part of the surgery is preferably 50% or less, more preferably 30% or less, most preferably of the total area of the anti-slip means 14 for catching the ankle. Preferably it is 20% or less.

As for the specific shape and size of the non-slip means 14 and 14 for holding the ankle, there is no particular limitation as long as the desired effect of the present invention can be obtained. For example, the shape of the non-slip means can be appropriately selected from the group consisting of square, rectangular, round and oval. Regarding the size, the length of the square side, the length of the long side of the rectangle, the diameter of the circle or the length of the long axis of the ellipse is 2 to 10 cm, preferably 2.5 to 7 cm, more preferably 3 to 5 cm.

As in the case of the non-slip means for holding the forefoot, the non-slip means 14, 14 for holding the ankle are preferably made of an adhesive material. Specific examples of this adhesive are as described above in connection with the anti-slip means for holding the forefoot.

In one of the preferred embodiments of the support structure of the invention, the sole and heel are connected via a connection made of a material of low elongation that is the same or similar to the material used to form the sole and the heel. The connection is called the "foot sole connection band"). It is desirable to use such midfoot plantar linking bands because this band further enhances the effectiveness of the present invention in preventing or correcting the valgus of the big toe and heel. For the material, elongation, and the like of the midfoot sole connection band, reference may be made to the above description with respect to the sole and the heel portion.

8 is a perspective view of another embodiment of a support structure of the present invention. This support structure has a toe opening that is separated into an opening for the first toe and another opening for the remaining toes. In the embodiment shown in Fig. 8, a big toe valgus correction flexible plate 16, which extends along the portion which comes into contact with the edge of the inner portion of the forefoot, is attached to the inner surface of the sole of the foot. As shown in FIG. 9, this big toe valgus correction flexible plate 16 has a wedge-shaped cross section whose thickness decreases continuously from the top to the bottom.

In many cases, the big toe valgus involves rotation of the first metatarsal bone and the first toe (thumb toe). For example, in the case of the right foot, the big toe often rotates clockwise when viewed from the toe tip. The big toe valgus correction flexible plate 16 can prevent or correct rotation of the big toe by giving a wedge effect to the big toe. A more detailed explanation of this is provided below. In the present invention, by the above-described configuration of the support structure, prevention or correction of flat foot is achieved by maintaining or correcting the position of the metatarsal interstitial (MTP) joint of the big toe at the intermediate position (normal position). However, when the MTP joint is fixed in the intermediate position, the inward muscles of the big toe relax. In this situation, when the big toe valgus straightening flexible plate 16 is positioned as shown in Figs. 8 and 10, the reaction force is effectively applied to the big toe by the wedge effect of the big toe valgus straightening flexible plate 16. It is thus possible to prevent and correct medial rotation of the big toe phalange (i.e., the big toe phalange is twisted so that the toenail faces the medial side).

As for the size of the big toe valgus correction flexible plate 16, the dimensions of the flexible plate 16, i.e. the length of the flexible plate from the stunning head to the middle of the metatarsal bone, and the wedge effect It is desirable to have a width sufficient for. Specifically, the size of the flexible plate 16 depends on the size of the foot and the like, but may be, for example, 3 to 15 cm in length and 1.5 to 5 cm in width. Moreover, it is preferable that the thickness in the top part of a flexible board is 1-8 mm, More preferably, it is 2-6 mm.

As shown in Figs. 9 and 10, in order to prevent the compression of the first toe on the MTP joint, it is preferable that the toe valgus correction flexible plate 16 has a cutout that matches the shape of the joint. The shape of this cutout is not particularly limited as long as the compression on the MTP joint of the first toe can be avoided. For example, as shown in FIG. 10, the flexible plate 16 in the big toe valgus correction flexible plate 16 is brought into contact only with a narrow area at the boundary between the bottom and the sides of the foot. It is preferable that the width of (16) be narrowed in the said part. There is no particular restriction on the width of the big toe valgus correction flexible plate 16 at this cutout (the minimum width of the flexible plate when the cutout is bent as shown in FIG. 9 or FIG. 10). However, the width of the toe valgus correction flexible plate 16 at this cutout is preferably 0.2 to 1.5 cm, more preferably 0.3 to 1.3 cm.

As shown in FIG. 9, it is preferable that the big toe valgus correction flexible plate 16 includes a shape memory alloy plate 17 extending in the longitudinal direction of the flexible plate. This shape memory alloy plate 17 enhances the effect of preventing and correcting foot deformation when weight is carried on the foot. The shape memory alloy plate 17 may be embedded in the big toe valgus flexible plate, or may be attached to the surface of the big toe valgus flexible plate.

When the big toe valgus straightening flexible plate 16 is used, it is advisable that the big toe valgus straightening flexible plate 16 is attached to the inner surface of the sole of the support structure in a position to come into contact with the foot in the manner shown in FIG. desirable. In particular, the flexible plate preferably extends along the boundary between the bottom and sides of the foot and also contacts the area from the stunning head to the middle of the metatarsal bone.

The big toe valgus straightening flexible plate 16 may be made of a conventional flexible resin. For example, at least one resin selected from the group consisting of vinyl chloride, polyethylene, polypropylene, polyethylene terephthalate, fluorocarbon resin, acrylic resin, ABS resin and urethane resin can be used.

Hereinafter, the present invention will be described in more detail with the following examples and comparative examples, but this is not intended to limit the scope of the present invention.

Example  One

The flat foot calibration was carried out using the support 6 shown in FIG. The patient was a 53-year-old woman with symptoms including deterioration of the longitudinal and transverse arches, the formation of feces in the second and third MTP joints, and the swelling of the big toe MTP joint (tongue formation), redness and pain. . The HV angle (thumb toe) was 25 ° (the HV angle is the angle between the big toe pelvis and the first metatarsal bone), and the M1M2 angle was 15 °. (M1M2 angle is the angle between the bone axis of the first metatarsal bone and the bone axis of the second metatarsal bone, which is indicative of the first metatarsal bone).

Hereinafter, the support 6 is explained in full detail. An elastic synthetic fiber cloth (73% polyurethane, 27% nylon) with the shape of an isometric trapezoid (short parallel side: 2 cm, long parallel side: 4 cm, and the remaining two sides: 8 cm) ), And a rectangular polypropylene nonwoven fabric (width: 16 cm, length: 8 cm) was used as the sole 8. The elongation (A) of the elastic synthetic fibrous fabric used as the instep 7 was 75% when measured under a load of 4.9 N (500 gf) and 160% when measured under a load of 17.7 N (1800 gf). , Where the elongation is measured in a direction corresponding to the width direction of the foot on which the support structure is worn. The elongation (B) of the polypropylene nonwoven used as the sole 8 was 5% when measured under a load of 4.9 N (500 gf) and 10% when measured under a load of 17.7 N (1800 gf). , Where the elongation is measured in a direction corresponding to the width direction of the foot on which the support structure is worn. Therefore, the ratio A / (B) of the elongation A of the instep 7 to the elongation B of the sole 8 was 15 when measured under a load of 4.9 N (500 gf), 17.7. It was 16 when measured under the load of N (1800 gf).

Both sides of 8 cm of the elastic synthetic fiber cloth used as the instep 7 were sewn to the corresponding 8 cm sides of the polypropylene nonwoven, respectively, to form a cylindrical support structure. The rectangular polypropylene nonwoven used as the sole 8 had two elliptical openings (dry flow openings 10 and 10), each having a major axis of 3 cm. The elliptical opening was formed in each part of the sole of the foot, which came into contact with the boundary between the metatarsal bone and the phalanx in the inner and outer sides of the forefoot.

A strip of a conventional double-sided tape was cut into the shape shown in Fig. 2 and used as a pair of anti-slip means 9 and 9 for holding the inner and outer portions of the forefoot.

The width of the patient's foot (measured with the patient's weight) at the boundary between the metatarsals and phalanges was 10.5 cm before the support was worn on the foot, but this value was reduced to 9.5 cm after the support was worn on the foot. . Also, after the support was worn on the foot, the HV angle of the foot was reduced from 25 ° to 18 ° and the M1M2 angle of the foot was reduced from 15 ° to 9 ° (both HV and M1M2 angles were measured with weight on the foot). will be). Eight hours after the support was worn on the foot, the patient's foot was observed and the foot width, HV angle, and M1M2 angle were all maintained at the above values obtained from the measurement immediately after the support was worn on the foot. The feet did not show any disease such as swelling, paralysis, pain and redness.

Comparative example  One

The support was produced in substantially the same manner as in Example 1, except that a pair of anti-slip means 9 for holding the inner and outer portions of the forefoot were not used. Calibration of the flatfoot was carried out in the same manner as in Example 1 using the prepared support. When measuring the width of the foot on which the support was worn, without placing the weight on the foot (ie, keeping the foot in the air), the width was reduced from 10.5 cm to 10.0 cm. However, the foot width returned to 10.5 cm in the patient's weight.

In addition, when the HV angle and the M1M2 angle of the foot were measured with the patient's weight loaded, there was almost no change in the HV and M1M2 angles of the foot before and after the support was put on the foot. 24 ° and about 14 °).

Industrial availability

By using the support structure of the present invention, not only can the lateral arch formed by wearing the support structure on the foot even when the user's weight is loaded, but also the garment pressure applied to the instep by the support structure can be suppressed to a relatively low level. The occurrence of edema and paralysis can be prevented. Accordingly, the present invention provides a comprehensive and comprehensive range of diseases that are accompanied by foot deformity (flat, big toe valgus, lowering of the arch of the foot due to PTTD (flattening of the sole) and heel valgus) without discomfort and pain to the user). Enable effective prevention and treatment. In addition, the above-described superior effects of the present invention can be obtained by using a thin material and a simple structure, so that the support structure of the present invention can be easily worn on the foot and can also be used with outdoor and indoor foot wear. . This means that the present support structure is easy to use on a daily basis and therefore the excellent prophylactic and therapeutic effects of the present invention described above can be easily improved to a large extent with the daily use of the support structure.
