Description

The present invention relates to a medical or sports soft device worn on an ankle joint for the prevention or treatment of various diseases of the ankle joint.
In particular, in the condition where the foot hangs down due to paralysis and became unstable walking, so-called stroke hemiplegic patients are targeted for prevention of whispering and twisting, assisting in securing the height from the floor to the toe (toe clearance) during walking. Therefore, the present invention relates to a medical soft brace used by being fixed to an ankle.

  There are many ankle diseases and disorders. The ankle joint may become unstable due to trauma such as sprain due to external force or paralysis due to other diseases (such as cerebrovascular disorder). Many appliances are used for such prevention and treatment (see Patent Document 1).

However, there has been no orthosis that can be easily attached to the ankle joint, particularly with one hand.
In the case where the paralysis has occurred in the ankle joint, when the paralysis that has been injured is relatively light, as the degree of paralysis becomes a recovery trend or a plateau with time, a transition is made from a rigid orthosis to a soft orthosis.

  The conventional soft devices used at this time generally use a plurality of belts to more firmly fix the periphery of the ankle joint, and the affected part is clamped twice or three times. When the wearer wears, the operation is basically performed on the one-hand healthy side, which causes troubles such as complicated operation and fixing the belt at an inappropriate position. In addition, it is difficult to wear one-handed devices used for the treatment and prevention of diseases and sprains other than those described above (see Patent Document 2, Patent Document 3, and Patent Document 4).

  In addition, there is a problem that there is a risk that unstable walking continues with the height from the floor surface to the toe being inferior because the problem of QOL surface of difficulty in wearing the orthosis makes it impossible to wear the orthosis (patent) Reference 5).

State. The common parts of the embodiments will be described using the same numbers.

Embodiment 1
Fig.1 (a)-FIG.1 (c) show the perspective view of the ankle joint orthosis of each structure which concerns on Embodiment 1 respectively, The cylindrical member 1 which coat | covers an ankle joint, and the sole part of the said cylindrical member 7 or two cross belts 2a and 2b that extend from the side to the left and right, cross over the instep and on the front of the lower leg and can be wound and fixed to the lower leg, and the belt at the intersection of the belts 2a and 2b An embodiment including insertion means for collecting the belts so that 2a and 2b are held adjacent to each other is shown.
As an insertion means for grouping the belts, an example using slits 11 in FIG. 1A, an example using slits 11 provided between the split belts 16 in FIG. 1B, and FIG. The smell shows an example using the holes 15. 1 (a) to 1 (c), 5 is a cross belt fixing portion, 6a to 6c are hook-and-loop fasteners, 8 is a buttocks, 9 is an instep, 10 is a front part of the lower leg, and 12 is a lower leg. , 13 indicates the toes.

  According to the embodiment of FIG. 1 (a), a slit 11 is provided in at least one cross belt as a guide so that the two cross belts extending left and right from the sole do not separate from each other, and the other cross belt is passed therethrough. Cross. The slit 11 has a length sufficient to allow the other cross belt to pass through in the cross belt flow direction. A plurality of slits may be provided, and the cross belt may be passed through the plurality of slits.

  According to the embodiment of FIG. 1B, at least one of the cross belts is provided with a plurality of divided belts 16 and 16 having a narrower width than the cross belt, and the other cross belt is used as the plurality of divided belts.

In particular, when the target person is a handicapped person such as a mild hemiplegic person or an elderly person, the structure of the present brace is effective for handling.

  Furthermore, a walking support function is obtained by using a member capable of elastic deformation as the cross belt (details will be described later). Specifically, it allows bottom flexion of the ankle at the time of ground contact during walking, and assists in dorsiflexion of the ankle joint from the time of getting out of bed to the next time of contact, thereby contributing to securing toe clearance. In other words, it is possible to walk with sufficient expression of the functions of the lower limbs of the person without excessively restricting the movement of the sole dorsiflexion. In addition, since a certain amount of foot movement is allowed, for those who can bend ankles even slightly, walking can be performed in a manner that allows the function of the ankle, so that the function of the damaged lower limbs can be restored. It leads to rehabilitation and supports the approach to natural walking.

  Furthermore, since the cross belt has a structure in which the tension can be controlled on the left and right, it can appropriately cope with the type of symptoms and the stage of recovery. When strong fixation is required, it is possible to make a cross belt that is difficult to stretch. Further, it is convenient to provide surface fasteners on the cylindrical member and the cross belt so that the cross belt can be temporarily fixed to the cylindrical member.

  Furthermore, as described above, if a different color is used for the surface fastener at the tip of each cross belt, and the same color material as the surface fastener of the cross belt is used for the portion for fixing the cross belt, the order of winding and fixing on the back of the foot is fixed. The corresponding adhesive member becomes clear. In addition, by attaching the same symbol or mark to the part that fixes the surface fastener and the cross belt at the tip of the cross belt or displaying the number, the order of winding and fixing the cross belt around the crus, and the corresponding adhesive member It is also possible to clarify.

  Furthermore, it is good to give anti-slip | skid property to the surface of the part applicable to a sole part, when mounting | wearing. Even if you wear shoes, it is difficult for the brace to slip in the shoes, and you can maintain proper support and fixation. In addition, when the shoes are taken off, it becomes difficult for the floor and slippers to slip, and an unexpected fall can be prevented.

Further, the surface fastener 6b of the cross belt 2b can be connected to the surface fastener 6c of the cross belt 2a by turning the cross belt 2b around the upper rear surface 20 of the tubular member. In addition, the surface fastener 6a of the cross belt 2a can be connected to the crus rear part 18 by making the cloth of the crus rear part 18 into a female shape.

[Embodiment of mounting method]
Next, taking the ankle joint orthosis shown in FIGS. 7A and 7B as an example, a method for mounting the ankle orthosis will be described below (see FIGS. 7A to 7E).

  In the ankle joint orthosis shown in FIG. 7 (a) and FIG. 7 (b), the stretchable fabric that extends the heel part 8 in multiple directions, the instep part 9 to the lower leg front part 10, and the lower leg rear part in one direction The tubular member 1 in which the direction perpendicular to the stretch is hardly stretchable and the sole 7 is made of the hardly stretchable fabric, and the cross belts 2 a and 2 b are crossed with the tubular member 1 inside the sole 7. The length of the cross belt provided on one of the cross belts 2b, which is fixed by the belt fixing portion 5, passes through the sole 7 and passes through a belt loop 14a (see FIG. 7B) provided outside the foot. Both cross belts cross from the instep part 9 at the front part 10 of the lower leg through the slit 11 along the direction. In the crus front part 10 of the tubular member 1, a crus belt 4 with one end fixed is folded back through a can 3 provided at a fixed distance from the fixed end in the crus circumference direction. The other end is connected to the cross belt 2a extending to the side on which the crus belt 4 is fixed, so that the cross belt and the crus belt 4 are pulled simultaneously.

The mounting method using this is as follows.
(1) All surface fasteners are not bonded (FIGS. 7A and 7B). However, the surface fastener 6a of the cross belt 2a on the side to which the crus belt 4 is connected can be easily mounted if the surface fastener 6d of the crus belt 4 is temporarily fixed.
(2) Next, as shown in FIGS. 7B and 7C, the loop member 21 is held, and the foot is inserted into the ankle joint orthosis.
(3) Next, as shown in FIG. 7 (d), the cross belt 2a to which the crus belt 4 is connected is wound around the tubular member 1 so as to apply tension in the direction reaching the crus rear part 18. Connect the hook-and-loop fastener.
(4) Finally, as shown in FIG. 7 (e), the cross belt 2 b on the side where the slits 11 are provided is wound around the tubular member 1 so as to apply tension in the direction reaching the crus rear part 18. The surface fastener 6b of the cross belt 2b is connected to the surface fastener 6c of the cross belt 2a.

(Embodiment of cylindrical member)
Next, an embodiment of the cylindrical member will be described with reference to FIG. FIG. 8 shows the tubular member of the ankle joint orthosis according to FIG. 5 or FIG. 7 (a), and shows a state where the can 3 is attached.

  The cylindrical member may be a straight cylindrical shape, but is preferably L-shaped. There may be a part that is open in part, such as the buttocks and the front part of the ankle joint.

  The cylindrical member can be formed of woven fabrics, knitted fabrics, non-woven fabrics, pile fabrics, foam materials, or the like made of natural fibers or chemical fibers, alone or arbitrarily selected and combined. Specific examples of the material include warp knitted fabric or weft knitted fabric jersey fabric, power net, which is formed by appropriately combining fibers such as cotton, wool, wool, rayon, acrylic, polyamide, polyester, polyurethane, and polyvinylidene chloride. There are elastic yarn blended knitted fabrics, double raschel fabric solid knitted fabrics, and the like. Furthermore, composite materials obtained by laminating foam materials such as these fabrics and rubber foams (chloroprene rubber, natural rubber, butyl rubber, styrene / butadiene rubber, isoprene rubber, etc.) and urethane foams (compressed urethane) can be used.

  In addition, surface fabric made of a material such as polyamide, polyester, polyvinylidene chloride, and the like can be used as a hook and loop fastener, and can be used for attaching and detaching between cylindrical members or between a cylindrical member and other members and adjusting their positions. It is advantageous.

  The cylindrical member can be formed from a single continuous cloth made of the above-mentioned materials, but can also be formed by stitching or cutting them into an appropriate size by sewing or bonding.

  In particular, since the ankle joint is a site with many irregularities, it must be able to follow the body surface, and in order to improve moderate compression and operability, stretch fabric, hard stretch fabric, It is preferable to use it in combination as appropriate according to the application. The stretchable fabric can be stretched in one direction or stretched in multiple directions. The hardly stretchable fabric is a fabric that does not easily stretch in any direction.

  Since the heel part 8 needs to follow the body surface at a site with many irregularities, it is preferable to use a stretchable fabric. Preferably, a stretchable fabric that extends in multiple directions is preferable because it can suppress the occurrence of displacement and floating. In addition, when strong fixability is required, a fabric that is stretchable only in one direction, a hardly stretchable fabric, or the like is used. The collar 8 may be provided with an opening.

In order to flexibly adapt to the physical characteristics of the subject, the instep part 9 to the lower leg front part 10 may be made of stretchable fabric in one direction and hardly stretchable fabric in the orthogonal direction. Preferably, a direction having elasticity in the circumferential direction from the instep portion 9 to the front part 10 of the lower leg is brought in a direction having difficulty in stretching in the vertical direction.
Further, instead of the above-described configuration, a fabric that is stretchable in both the circumferential direction and the vertical direction is used, but a fabric that is less likely to extend in the vertical direction than the circumferential direction may be used.
By using the above-described configuration, it is possible to flexibly adapt to various insteps and lower leg circumferences, and size development can be minimized. Further, there is an advantage that the legs can be easily passed through the tubular member as if wearing socks.

Like the instep part 9 to the crus front part 10, the crus rear part 18 is flexible in one direction and stretchable in one direction and hardly stretched in the orthogonal direction. It is recommended to use sex cloth. Preferably, a direction having elasticity in the circumferential direction of the lower leg rear portion 10 and a direction having difficulty in elasticity in the vertical direction may be brought.
Further, instead of the above-described configuration, a fabric that is stretchable in both the circumferential direction and the vertical direction is used, but a fabric that is less likely to extend in the vertical direction than the circumferential direction may be used.
By using the configuration as described above, it is possible to flexibly adapt to various circumferences of the lower leg, and the size development can be minimized. Furthermore, since the vertical direction is difficult to extend, it can be mounted without buckling. In addition, a fabric that has elasticity such that the cylindrical shape is retained when the fabric is stretched in one direction and hardly stretched or stretched relatively in the orthogonal direction by hand when worn. When an auxiliary member is added along the circumferential direction in the upper end portion of the cylindrical member or in the vicinity thereof, the opening portion is held on the upper portion of the cylindrical member, so that the foot tip can easily enter. It is.
As the auxiliary member, various substrates, plastic or metal sheets or linear objects, resins (application or impregnation), tubes or packs containing fluid, and the like can be used.

  The sole 7 is preferably made of a hardly stretchable fabric for the purpose of supporting toe clearance. Although the cross belt is mainly used to secure the toe clearance, the use of a hardly stretchable fabric can exert an effect of supporting the toe clearance while supporting a relatively heavy foot weight. Preferably, it is a non-stretchable fabric and is more effective for supporting toe clearance.

  If a convex portion such as a tongue, a loop-shaped member, a hole, or the like is provided above the upper rear surface of the cylindrical member 1, it is easy to grip with a finger or to hook a finger when wearing it. When a loop-shaped member or hole is provided, even when a finger cannot be directly hung, it can be pulled with a hook or string. Further, considering that ordinary shoes can be worn, the maximum thickness of the fabric used is preferably 5 mm or less. Furthermore, when composing the tubular member, it is preferable to select a fabric for the breathable member in consideration of wearing comfort. Furthermore, it is good to give non-slip property to the surface of the sole 7. Even if you wear shoes, it is difficult for the brace to slip in the shoes, and you can maintain proper support and fixation. In addition, when the shoes are taken off, it becomes difficult for the floor and slippers to slip, and an unexpected fall can be prevented.

[Embodiments of cross belt and lower leg belt]
Cross belts and crus belts are elastic woven fabrics, elastic woven belts, non-woven fabrics such as polyurethane and SIS, elastic rubbers such as polyurethane, synthetic rubber (SBR, IR, acrylic rubber, silicone rubber, etc.), natural rubber, etc. It can be formed in a band shape, a sheet shape, or a thread shape using a body or the like. Particularly preferably, the belt or belt member is installed, and an engaging means such as a hook-and-loop fastener is attached to the front end of the belt member so as to be detachable from the tubular member so that the compression and fixing force can be adjusted. Become.
In order to improve the fit of the cross belt to the ankle joint, it is preferable to install the cross belt as follows.
(1) The cross belt fixing portion is installed with an angle in the direction in which the cross belt extends (direction toward the lower leg) with respect to the circumferential direction of the foot portion of the cylindrical member. Alternatively, the cross belt is extended in parallel to the circumferential direction of the leg portion of the cylindrical member, and the fixing line of the cross belt fixing portion is angled with respect to the belt width direction so as to be V-shaped so that the cross belt expands and contracts. The outside is made longer with respect to the width direction of the part. That is, the V-shaped closed side is the outside and the open side is the inside.
Also, (2) providing a cross-stretchable member at the end of the cross belt, or applying a process that makes it difficult to stretch so that the outer stretchable part becomes longer with respect to the width direction of the cross belt. Good. Further, (3) (1) and (2) may be used in combination.
A suitable means among the above can be used depending on the state of the foot joint part to be worn.
In addition, when a loop member, hole, or the like is provided at the tip of the cross belt, it is easy to operate by hooking a finger when wearing the cross belt. Even when a finger cannot be directly hung, it can be pulled with a hook or string.
