TECHNICAL FIELD OF THE INVENTION
The present invention relates to a medical or sports ankle joint which is fixed to an ankle for prevention of occurrence, relapse prevention and treatment of trauma such as varus or valgus sprain in an ankle joint, and correction or rehabilitation for contracture. About supporters.
[0002]
[Prior art]
There are various methods for the prevention, recurrence prevention and treatment of trauma such as sprains in the ankle joint, and correction and rehabilitation for contractures caused by congenital or acquired diseases. , A taping tape, a bandage, a supporter, and the like are used, and a plurality of these may be used in some cases. Each of these means has its own characteristics, and is selected according to the condition of the affected part of the user, the situation of use, and the like. Among them, the supporter has the following advantages, and is therefore used in various situations as a useful means for preventing the occurrence of traumatic injury, preventing recurrence and treating. First, the supporter can be mounted easily and in a short time without requiring special skills or an auxiliary person having the same, for example, a cast or a taping tape. In addition, when it is preferable to wear the supporter for a long time depending on the condition of the affected part, the supporter has better stability and durability for continuous use than taping tape and bandage, and as a result, running cost at the time of use is low. Yes.
[0003]
There are various types of ankle supporters currently used. One of them is a tubular body that covers the periphery of the ankle joint, and a supporter that is provided on the outer surface and includes a belt that fastens and fixes the ankle joint. As a specific structure of this type of supporter, a tubular body covering the circumference of the ankle joint, one end is attached to the outer surface of the inner and ankles of the tubular body, and an elastic belt extending from the sole to the upper part of the heel through the back of the foot. A supporter (for example, see Patent Document 1), a tubular body covering the upper and lower periphery of the ankle joint, a belt extending from the outer surface of the tubular body through the sole to the outer surface on the opposite side, and a tubular body. A supporter provided with a belt extending from the portion corresponding to the Achilles tendon at the rear to the outside surface around the sole (for example, see Patent Document 2), a tubular body covering around the ankle joint, and covering the ankle inside the tubular body There is a plate-like member, a supporter provided with a belt connected to the lower part of the plate-like member or the sole of the tubular body and passing through the sole to the outer surface of the tubular body (for example, see Patent Document 3).
[0004]
All of these supporters try to fix the ankle joint by applying force from a specific direction around the ankle joint by using a belt or support plate that winds around the back of the foot or the sole. However, it was not possible to sufficiently prevent the supporter from shifting and swaying, and to sufficiently maintain the stability of the sole. In other words, the sole has a large contact area with the supporter, and is a part where the overall weight of the user is concentrated, and because it generally has an uneven arch shape, it is a part where the displacement of the supporter is very likely to occur. However, conventional supporters did not have a particularly advantageous structure to suppress it. As a result, the shift and twist of the supporter that occurred at the sole part spread further around the foot due to the movement of the foot, so the supporter will be fixed at a position shifted from the appropriate position, and the supporter's original function will be sufficiently Can not demonstrate. In addition, this type of supporter generally uses a plurality of belts to more firmly fix the circumference of the ankle joint, and tightens the affected part two or three times. However, those who are not accustomed to wearing the ankle supporter In addition, for an elderly person or a person with a disability, the operation becomes complicated, and the belt may be fixed at an inappropriate position.
[0005]
Further, as a method of stabilizing the sole, a supporter in which a sole plate is integrally attached to a portion corresponding to the sole of a tubular body that covers the entire ankle joint has been proposed (for example, Patent Literature 4, Patent Literature 4). 5, see). However, since the shape of the sole varies greatly between individuals, when using this type of supporter, it takes time to adjust the appropriate sole plate according to the user, and when using shoes, It was necessary to consider compatibility with shoes. In addition, by attaching the sole plate to the tubular body integrally, there is an advantage that the displacement between the sole plate and the tubular body is prevented, but there is a special configuration that prevents the supporter itself from shifting from the affected part. Therefore, even if the sole plate fits the user, there is a possibility that the supporter may gradually shift with use.
[0006]
Furthermore, in order to correct the function of the lower limb damaged by disorders such as stroke hemiplegia and peroneal nerve palsy, an elastic body is inserted between the first wearing body attached to the foot and the second wearing body attached to the thigh. There has also been proposed an orthosis in which the toes are lifted upward by the elastic force of the stretchable body (for example, Patent Document 6). According to this brace, the toes can be lifted upward without blocking the movement of the feet, and the toes can be prevented from being caught on the floor or a step when walking, but two wearing bodies are used. Therefore, the wearing is troublesome, and since the elastic body applies a local force between the two wearing bodies, the function of the damaged foot cannot be sufficiently protected. In addition, in the case of an injury due to paralysis, the tip of the foot is lowered, and the foot is liable to varus, which may cause a sprain. However, this supporter does not have a function to sufficiently suppress the varus.

[Problems to be solved by the invention]
An object of the present invention is to provide an ankle supporter which can fix an ankle joint at an appropriate position so as not to be displaced, apply stable support and appropriate compression, and is easy to operate and easy to handle. It is in. In particular, it is an object of the present invention to provide an ankle supporter that sufficiently suppresses varus or valgus movement without excessively hindering the sole dorsiflexion movement of the foot and maintains the stability of the sole.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, in the present invention, the ankle, a tubular member covering a part of the sole and a part of the back of the foot, and from one outer surface of the tubular member to the sole of the tubular member. Tension applying means for applying tension in a direction reaching the other outer surface of the cylindrical member through the corresponding portion, and the width of one end of the cylindrical member of the tension applying means located on one outer surface and the one end thereof are installed. The ratio of the width of the cylindrical member to be formed is in the range of 0.4: 1.0 to 1.0: 1.0, and an upward force can be applied to the forefoot by the tension applying means.
[0010]
Further, in the present invention, the tubular member covering the ankle, a part of the sole, and a part of the back of the foot, and a part corresponding to the sole of the tubular member passing from the part corresponding to the sole of the tubular member. Tension applying means for applying tension in a direction reaching one of the outer surfaces of the tubular member, and the width and one end of one end located at a portion corresponding to the sole of the tubular member of the tension applying means are installed. The ratio of the width of the tubular member is in the range of 0.4: 1.0 to 1.0: 1.0, and an upward force can be applied to the forefoot by the tension applying means.
[0011]
The width of one end located on one outer surface of the tubular member of the tension applying means, or the width of one end located on a portion corresponding to the sole of the tubular member of the tension applying means is formed wider than the width of the other end. Is preferred.
[0012]
The tubular member can be formed by using a woven fabric, a knitted fabric, a nonwoven fabric, a pile fabric, a foam material, or the like made of natural fibers and chemical fibers alone or in any combination. Specific examples thereof include, for example, warp knit or weft knitted jersey fabric, power net made by appropriately combining fibers such as cotton, wool, wool, rayon, acrylic, polyamide, polyester, polyurethane, and polyvinylidene chloride. And three-dimensional knitted fabric of double Raschel fabric. Further, a composite material obtained by laminating a foam material such as a rubber foam (chloroprene rubber, natural rubber, butyl rubber, styrene / butadiene rubber, isoprene rubber, etc.) or a urethane foam (compressed urethane) can be used.
[0013]
The tubular member can be formed from a single piece of continuous cloth of the above-described materials, but can also be formed by cutting and cutting the pieces to an appropriate size by sewing or bonding. In particular, in areas with many irregularities such as the upper back of the foot and the heel, it is necessary to follow the body surface, and a stretchy cloth is used partially or entirely to improve moderate compression and operability. Is preferred. The elasticity of the fabric of the tubular member can be freely adjusted by the characteristics of the fibers used in the fabric, the blend ratio thereof, the combination pattern of the fabrics, and the like. In addition, a surface fabric made of a pile of a material such as polyamide, polyester, or polyvinylidene chloride can be used as a hook-and-loop fastener, and is used for attaching and detaching between cylindrical members or between a cylindrical member and another member, and adjusting their positions. It is advantageous.
[0014]
The tubular member can be formed in a substantially cylindrical shape with an appropriate size so as to cover the ankle, a part of the sole, and a part of the back of the foot. In addition to the sewn one, a part of or the entirety of the tubular member provided with an open portion can be used. The open part may be provided on the anterior side (dorsal side) or the posterior side (Achilles tendon side) or on any side side, and the cut of the opening may be straight, curved, or a combination of both. Can be used. When an open portion is provided, one open side piece is attached to the other side piece with a hook-and-loop fastener or the like so that it can be formed into a cylindrical shape. By providing such an open portion, the manner of attachment of the hook-and-loop fastener or the like can be adjusted, and the most appropriate compression force can be applied to the affected part having individual differences. The tubular member only needs to cover at least a part of the ankle, a part of the sole, and a part of the sole of the foot, and can cover a part of the lower leg in consideration of a disease state or a use condition. Alternatively, slits or holes may be formed as appropriate to improve air permeability.
[0015]
The tension applying means installed on the tubular member is not particularly limited, but specifically, one end of a stretchable or non-stretchable strip-shaped material is attached to the outer surface of the tubular member or the sole of the tubular member. Attach to the corresponding portion and install so that the other end can be pulled up to the opposite outer surface, from the portion corresponding to the outer surface of the tubular member or the sole of the tubular member to the sole of the tubular member There is a method of installing a material having a higher elasticity than the material of the tubular member in a region passing through the portion and extending in the direction of the outer surface opposite to the tubular portion. The method of installing the elastic material can be appropriately selected depending on the form of the elastic material. For example, if the material is a band-like or sheet-like material, the material is placed on the cylindrical material (when the material has a laminated structure, 2) Attachment is performed by sewing, bonding, welding, or the like, and a thread-like material is sewn into a tubular member to apply tension. Further, a method of impregnating and applying a synthetic resin having elasticity to a cloth in a liquid state, and then drying the resin can also be used. Of course, these elastic materials themselves may constitute part or all of the above-mentioned region of the tubular member, and may be applied with tension. Particularly preferably, the tension applying means is a method of installing a band-shaped material, and by attaching and detaching an engaging means such as a hook-and-loop fastener to the end of the band so as to be detachable from the cylindrical member, it is possible to adjust the pressing and fixing force. Become like In addition, since the pressure and the fixing force can be easily changed by appropriately selecting the properties of the material used for the band-shaped member, the supporter can be applied to a wide range of patients. In other words, the use of a non-stretchable material or a material with a high elasticity is advantageous in firmly and stably fixing the limb position, and a stretchy material or a material with a low elasticity is used. If there is, a certain degree of mobility is required for an affected part such as an athlete or a patient performing rehabilitation, and the present invention can be applied.
[0016]
Further, the tension applying means is attached to the outer surface of the tubular member or a portion corresponding to the sole of the tubular member in order to apply a balanced force to the sole and to support and stabilize the sole as a whole. The ratio of the width of the end to the width of the tubular member on which it is installed is preferably in the range of 0.4: 1.0 to 1.0: 1.0, preferably 0.5: 1.0 to 0.1. More preferably, the ratio is in the range of 8: 1.0. If the width of one end of the tension applying means is 0.4 or less with respect to the width of the tubular member, it becomes difficult to obtain stability of the sole portion, and it becomes easy for the local pressure to be applied. And the cylindrical member may be easily worn. On the other hand, if it is 1.0 or more, that is, if the width of the tension applying means is wider than the width of the cylindrical member, the bulk of the entire supporter increases, which deteriorates the feeling of wearing and is economically disadvantageous. In addition, when one end is attached to the outer surface of the tubular member, the tension applying means effectively applies an upward force to the forefoot and sufficiently suppresses varus or valgus movement. The other end is installed at a position higher than the position of the tubular member at the one end on the other outer surface of the tubular member, and one end is attached to a portion corresponding to the sole of the tubular member, When the tension applying means is provided in a direction passing through a portion corresponding to the sole of the tubular member and reaching one of the outer surfaces of the tubular member, the position at which the tension applying means can pass through at least a half or more portion of the sole. It is preferable that one end is installed and the other end is installed at a position higher than the sole on the outer surface of the tubular member. Further, this tension applying means may pass through a position corresponding to the vicinity of the heel portion of the sole, in order to suppress the lateral sway of the heel movement which triggers the varus or valgus movement. preferable. At this time, the width of one end located on the outer surface of the tubular member or the portion corresponding to the sole of the tubular member of the tension applying means is formed to be wider than the width of the other end, or from one end to the other end. Is formed so that the width generally decreases toward. By doing so, the vicinity of one end of the wide tension applying means can sufficiently support the sole portion, while the other end having a narrower width improves the followability between the supporter and the foot. At the same time, the feeling of wearing is improved because the movement of the foot is not unnecessarily restricted. In particular, when a belt-shaped member is used as the tension applying means, it is easy to hold the narrower end width, and the position of the belt-shaped member is easily adjusted. Further, the belt-shaped member may be formed by joining a plurality of belt members. One end of the belt member is installed in a portion that needs to be particularly tensioned (for example, near a heel or a toe), and the other end is joined together so as not to be separated. Further, if the materials used for the plurality of belt members are formed of materials having different properties, the applied tension can be partially changed, and the application according to the condition of the affected part can be performed. Although the number of belt members is not particularly limited, it is preferable that two belt members are formed in a substantially V-shape, and since a gap is formed between the two belt members, a portion that does not cover the tubular member is formed, so that the belt can follow. It is economically advantageous as well as improving the performance. In addition, if the belt member is appropriately provided with slits and holes, air permeability can be secured, and the ability to follow the foot can be further enhanced.
[0017]
When a belt-like member is used as the tension applying means, a contact side can be provided near a portion where the belt-like member is attached to the tubular member. By providing the contact side, wrinkles and warping are less likely to occur in the tubular member, and the attachment of the belt-shaped member to the tubular member can be reinforced. It is sufficient that the contact side covers at least the portion of the belt-shaped member attached to the tubular member, and the shape and size are not limited. However, it is preferable that the contact side is installed so as to be parallel to the axial direction of the tubular member. As the contact side, the same material as that used for the tubular member can be used.
[0018]
Furthermore, if the tension applying means is a belt-shaped member, the portion extending from left to right from the portion corresponding to the sole of the tubular member, crossing the figure of 8 on the portion corresponding to the back of the foot, and A band-shaped member may be formed so that the band-shaped member can be wound and fixed so as to reach the vicinity of the upper portion. By fixing the band-shaped member around the cylindrical member, both plantar flexion and dorsiflexion can be restricted, and a stronger fixing force can be obtained. Is obtained. This band-shaped member may be configured such that one end of each of the two band-shaped members is attached to the sole of the foot, and the band-shaped member is raised from the left and right, and the other end is detachably formed on the tubular member. May be attached to a portion corresponding to the sole of the tubular member, and the both ends may be detachably formed on the tubular member by rising from the left and right of the portion corresponding to the sole. The belt-shaped member is preferably elastic, and it is preferable to provide an engaging means such as a hook-and-loop fastener at an end thereof so that the belt-shaped member can be attached to and detached from the tubular member.
[0019]
By providing the surface of the tension applying means with a non-slip property, even if the shoe is worn while the supporter is attached, the supporter is unlikely to slip in the shoe, and appropriate support and fixation can be maintained. In addition, even when the shoes are taken off, the floor and the slippers are less likely to slip, and it is possible to prevent a person with weak legs such as the elderly from slipping and falling. As a means for imparting anti-slip properties, a conventional method can be used. In particular, it is preferable to use an elastomer material processed into various forms. Specifically, a material obtained by processing an elastomer material into a form such as a thread, a sheet, or a foam is installed on a part or all of the surface of the tension applying means, or a liquid elastomer material is partially applied to the tension applying means. Or, it is applied to all to impart anti-slip properties. Preferably as an elastomer material, natural rubber, isoprene rubber, chlorinated rubber, butadiene rubber, butyl rubber, styrene rubber, styrene-butadiene rubber, chloroprene rubber, nitrile rubber, acrylic rubber, polysulfide rubber, silicone rubber, polyethylene rubber, fluorine rubber Raw rubbers such as polyurethane rubber, ABS and epichlorohydrin rubber, and thermoplastic elastomers such as polystyrene, polyolefin, polyurethane, polyester, polyamide, polyvinyl chloride, and ethylene-vinyl acetate can be used.
[0020]
For the purpose of suppressing varus or valgus of the ankle joint, a support made of metal or plastic may be provided on both side surfaces of the tubular member. As a method of attaching the support to the tubular member, a pocket is provided in the tubular member, inserted into the inside, sewn into the fabric of the tubular member, or attached and detached to the outer surface of the tubular member by a hook-and-loop fastener or the like. Can be mounted freely.
[0021]

In this way, the tubular member 1 is securely fixed to each part of the back and sole of the foot, and then the band-shaped member 6 passes through the sole 34 from one outer surface of the tubular member 1 and the outside of the other. By reaching the side surface and being engaged on the tubular member, the portion corresponding to the sole of the tubular member 1 is pressed against the sole by the band-shaped member 6 so that the tubular member 6 does not deviate from the foot, Moreover, an upward force is applied to the forefoot.
[0025]
3 and 4 show different embodiments of the present invention, wherein a is a left side view, b is a perspective view in a mounted state, and the same parts as those in FIG. 1 are denoted by the same reference numerals. The embodiment of FIG. 3 is different from the embodiment of FIG. 1 in that a belt-shaped member 11 is formed by joining two belt members 12 and 13 into a substantially V-shape as a tension applying means. That is, one end 14, 15 of the two belts is attached to the outer surface of the tubular member 1, and the other ends of the belts are joined to each other so that the belt fastener 16 can be engaged on the tubular member 1. . In mounting, the same method as the engaging method described in the embodiment of FIGS. 1 and 2 is applied. The embodiment of FIG. 4 is different from the embodiment of FIG. 1 in that the belt-like member 17 is formed by joining two belt members 18 and 19 into a substantially V-shape. The difference is that two are attached to the. The width W of the portion of the two belt-shaped members 18 and 19 fixed to the sole of the foot ₁ It is also preferable to select the ratio between the width and the width L of the cylindrical member 17 at the portion to be fixed in the range of 0.4: 1.0 to 1.0: 1.0. At the time of mounting, two band-like members 17 extending from the center of the sole are attached to the back of the foot, and stretched to the opposite side so as to intersect each other at the top of the back of the foot in a figure of eight, and near the upper part of the heel. It is engaged on the tubular member 1 by the surface fastener 20.
[0026]
FIGS. 1 and 3 of the above-described embodiment show an example in which the band-shaped member is attached in a direction to prevent inversion of the foot. However, the band-shaped member is attached to the outer surface on the opposite side to FIGS. It is also possible to prevent eversion, and there is basically no change in the configuration other than the mounting position of the band-shaped member in that case.
[0027]
FIGS. 5 and 6 each show still another embodiment of the present invention, in which a is a left side view, b is a perspective view in a mounted state, and the same parts as those in FIG. These embodiments differ from the embodiment of FIG. 1 in the configuration of the tension applying means. That is, the tension applying means 21 in the embodiment of FIG. 5 extends from the outer surface of the tubular member through the portion corresponding to the sole portion, extends in the direction of the opposite outer surface, passes through the portion corresponding to the back of the foot, and passes through the heel portion. The cloth which has higher elasticity than the cloth of the cylindrical member is sewn to a region reaching the vicinity of the upper part of the portion corresponding to. The elasticity of the fabric used for the tension applying means can be appropriately selected in consideration of the disease state of the user of the supporter and the state of use (sports, rehabilitation, etc.). In addition, the tension applying means 22 in the embodiment of FIG. 6 extends from the outer surface of the tubular member through the portion corresponding to the sole and in the direction of the opposite outer surface, passes through the portion corresponding to the back of the foot, and The region reaching the vicinity of the upper portion of the portion corresponding to the portion is configured to have a knitting structure having higher elasticity than other regions of the tubular member. As a method of forming a highly elastic knitting structure, knitting can be performed with an elastic material such as polyurethane fiber, or the number of yarns used for knitting can be increased compared to other regions. According to this method, it is not necessary to overlap another material on the tubular member, so that the thickness of the tension applying means can be reduced. In the embodiment shown in FIGS. 5 and 6, since the adjustment of the strength of the tension required when the belt-shaped member is used as the tension applying means is not particularly required, it can be easily attached and detached, and the degree of application of the tension every time it is used. A constant tension can be obtained every time without changing the tension.
