Description

Elastic Neutral Ankle Foot Orthosis

The present invention relates to an elastic neutral ankle assistor.

Paralyzed patients due to cerebrovascular disease have weakened muscle activity around the ankle joint due to paralysis of the nervous system. That is, due to the stiff paralysis of plantar flexors, the foot heel does not touch the ground in the early standing phase, and thus the foot drop phenomenon occurs.

Foot drop is a paralysis of the nervous system that can not lift the foot due to the decrease or loss of muscle activity around the ankle. The cause of the foot drainage is caused by inadequate activity of the tibialis anterior around the ankle due to paralysis of the central and peripheral nervous system, especially in patients with convulsive paralysis. That is, in order to compensate for this, the paralyzed patient walks on a circumduction gait, resulting in an inefficient gait pattern such as a slow walking speed and a large increase in energy consumption. Ankle foot orthosis, which is worn as a physical aid to improve the walking of such foot and foot patients, has been widely used.

Korean Registered Patent Publication No. 10-1682450, Korean Registered Patent Publication No. 10-1531203, and Korean Registered Patent Publication No. 10-1767996 disclose an ankle assist device in which a foot support part and a leg support part are formed of plastic.

The conventional ankle assist device is formed of an elastic material of the foot support portion and the leg support portion integrally formed, or connected to each of the foot support portion and the leg support portion formed of plastic to the joint portion and the structure to elastically support the relatively rotated angle with the spring Have.

However, since the support is formed three-dimensionally by plastic, the weight is heavy and bulky, which causes inconvenience to the user. In addition, it is difficult for the patient to actively carry out the walking training because the plastic foot support restricts the unique water solubility of the sole in the walking training.

Meanwhile, the inversion refers to a state in which the talus and the middle bone face outward, and when the foot is viewed from above, the heel enters the inside of the tibia. Eversion is a state where the talus and the middle bone are directed inwards, and when viewed from the top, the heel is outward.

When walking, the walking of the varus and valgus occurs sequentially while walking, in the case of the average person, the degree of valgus and valgus is small within a predetermined range. However, if the inner or outer valgus is severe, the foot is inclined to be inclined, so that the weight bearing capacity becomes small and the impact divergence becomes difficult.

Korean Utility Model Publication No. 20-0202448 discloses a low flexion foot foot brace. The conventional low buckling varus brace is provided with a first fixing band portion which is installed to be riveted or sealed in one end fastening ring and coupling ring to be fastened to the knee joint portion; A second fixing band part installed at one end such that the fastening ring and the hook are riveted or sealed so as to be fastened to the metatarsal bone of the foot; The upper side is coupled to the engaging ring of the first fixed band portion, the lower side is provided with a fixing ring and an adjustment ring is fastened to the hook of the second fixing band portion includes an elastic band portion connecting the first fixed band portion and the second fixed band portion do.

However, the conventional low buckling varus brace has a problem that the two fixing bands fixed to the legs and feet hardly press the legs and feet to give discomfort and loosely fixed on the contrary.

Moreover, since the elastic band portion only exerts an elastic force upward from the outside of the metatarsal bone, there is a problem that it is difficult to fully support the gait of the inner foot patient.

It is an object of the present invention to provide an ankle assistor, which is very easy to manufacture, carry, detach and use and can easily adjust the elastic force.

In particular, it is an object of the present invention to provide a neutral neutral ankle assistor that can fully support the active movement of muscles when the varus or valgus patients walk.

The elastic neutral ankle assistant of the present invention includes a fabric belt 10 having a predetermined width, length and thickness, and an elastic band 40 having one end fixed to the fabric belt.

The fabric belt 10 is literally made of fabric paper and may have a rectangular shape having a length of 50 to 70 cm and a width of 10 to 20 cm.

Since the fabric belt 10 is made of a woven paper having a predetermined thickness, it can be easily bent or folded. Thus, since the fabric belt 10 has sufficient tensile strength when the leg is wound around the fabric belt 10, it can be fixed by pulling strongly, and the fabric belt 10 can be fixed so as not to move after being fixed.

In order to fix the fabric belt 10 in a state of being wound tightly on the leg, an attachment strap 20 may be provided.

Attachment strap 20 is fixed to the front or back of the fabric belt 10 can be fixed to the fabric belt 10 wound around the human leg. Specifically, the attachment strap 20 is preferably fixed between the knee and the calf muscle.

Attachment strap 20 may be fixed by winding the strap to the fabric belt 10 and the both ends of the strap by a buckle, in this case, it is necessary to provide a plurality of straps, and when detaching it requires a plurality of operations and the fabric belt (10) ), It is necessary to pull the strap so hard that the leg is tightened too much.

Thus, in the present invention, the attachment strap 20 is preferably made of a Velcro tape. That is, the attachment strap 20 may be attached to the female strap portion and the male strap portion in the form of velcro.

Attachment strap 20 is the first strap portion 22 provided on the front of the fabric belt 10, the second strap portion provided on the back of the fabric belt 10 and coupled to the first strap portion ( 24).

The back of the fabric belt 10 shown in Figure 1 forms an inner circumferential surface that contacts the leg when the fabric belt 10 is wound on the leg, the front of the fabric belt 10 shown in Figure 2 is visible from the outside when wound on the leg It forms the outer circumference.

The first strap portion 22 is a female velcro tape portion and may be coupled to the rear end portion of the fabric belt 10 (near the left end portion in FIG. 1). That is, the first strap portion 22 may be provided with a plurality of hooks on one surface of the strap.

The second strap portion 24 is a male velcro tape portion and may be coupled to one end portion of the back of the fabric belt 10 by sewing. That is, the second strap portion 24 may be provided with a plurality of hooks on one surface of the strap.

The first strap portion 22 may be formed to a length of about 1/4 of the length of the fabric belt 10, the second strap portion 24 is equal to or slightly larger than the length of the first strap portion 22 It can be formed in length.

Since the attachment strap 20 is made of male / female velcro tape, the user can easily fix the fabric belt 10 by winding it on the leg.

Elastic band 40 is a band of elastic and elastic material can be fixed by sewing one end to the fabric belt (10).

Elastic band 40 may be formed so that one end is coupled to the back of the fabric belt 10 and the other end is wrapped around the front end of the foot of the person. Middle portion of the elastic band 40 may be rotated to wrap more than 360 degrees on the leg.

Elastic band 40 has a width of about 5 ~ 15cm, as shown in Figure 1 can be fixed by sewing one end to extend downward on the back of the fabric belt (10). As shown in Figure 3, one end of the elastic band 40 can be fixed by sewing slightly above the middle of the longitudinal length of the fabric belt (10).

Elastic band 40 provides an elastic force to pull the front heel of the foot to the side when walking. For example, when the varus patient steps on the foot, the elastic band 40 may provide an elastic force that pulls the ankle of the foot outward. In the case of valgus patients, the elastic band 40 may provide an elastic force to pull the forefoot of the foot inward.

The elastic band 40 is worn so as to be wound around the legs to provide the elastic force to be pulled to the side, the lower end of the elastic band 40 is first hooked to the toe side, the middle part is wound around the legs, and the fabric belt 10 is wound around the legs. It is fixed by the attachment strap 20.

The size of the elastic force of the elastic band 40 may be appropriately adjusted according to the elastic modulus and the length of the elastic band 40 according to the material of the elastic band 40.

Elastic band 40 may be formed in the form of a rubber band having a predetermined width, has a sufficiently large elastic force and good elasticity, it is good to be made of a material excellent in durability without tearing well when sewing.

It is preferable to have an elastic band adjuster 50 to adjust the length of the elastic band 40. The elastic band adjuster 50 is provided on the back of the fabric belt 10, it may be disposed in the portion where the elastic band 40 is coupled.

Elastic band adjuster 50 is coupled to both ends of the back of the fabric belt 10, the plurality of support members 52, 54, 56 that can be fixed by inserting the elastic band 40 between the fabric belt and selectively It is preferable to include).

Since each support member 52, 54, 56 is coupled to the fabric belt 10 by only its both ends, the elastic band 40 may be inserted between the support member and the fabric belt 10.

In the embodiment shown in FIG. 3, the elastic band adjuster 50 includes a first support member 52, a second support member 54, and a third support member 56. Increasing the number of supporting members further, the length of the elastic band adjuster 50 can be further subdivided and adjusted, but the configuration may be more complicated and more difficult to use.

The first support member 52 is fixed in the left and right direction by sewing both ends on the fixed one end of the elastic band 40 in the fabric belt 10, and the second support member 54 is the first support member 52. Both sides of the right and left under the sewing can be fixed in the left and right directions. The third support member 56 may be fixed in the left and right directions by sewing both ends at the bottom of the second support member 54.

Each support member 52, 54, 56 may be spaced apart from the elastic band 40 except for both ends sewn to the fabric belt 10 so that the elastic band 40 may be inserted therebetween. To this end, each support member 52, 54, 56 is formed with a length larger than the width of the elastic band (40).

Each support member 52, 54, 56 may include a support bar (not shown) made of a hard material such as plastic therein so as not to bend when pulled by the elastic band 40.

Since the elastic band 40 is mainly made of a rubber material, when the elastic band 40 pulls the support member, the support member is bent so that the elastic band 40 can be driven to the center portion of the support member. Then, since the length of the elastic band 40 is increased, each support member (52, 54, 56) is provided with a rigid support bar therein so as not to be deformed even when pulled by the elastic band (40).

On the other hand, when the elastic ankle aid is wound on the leg is provided with a elastic close band 30 on the back of the fabric belt 10 in contact with the leg, it is preferable to close the fabric belt 10 to the human leg and prevent movement. .

The elastic close band 30 may be made of a rubber material similar to the elastic band 40, but may have a different elastic modulus from the elastic band 40. In addition, the elastic close band 30 may be formed of a length of about 3/4 of the fabric belt 10, the back of the fabric belt 10 is coupled to the side of the first strap portion 22 by sewing Can be.

Fabric belt 10 is provided with an attachment strap 20 can be fixed to maintain the state wound on the leg, but because the elastic band 40 is pulled in use, the fabric belt 10 can be moved relative to the leg.

The elastic close band 30 allows the fabric belt 10 to be pressed onto the leg and provides friction between the leg and the fabric belt 10, thereby preventing the fabric belt 10 from moving against the leg.

Elastic contact band 30 is shown on the back of the fabric belt 10 by a pair of first sewing lines (L1) at both ends and a pair of second sewing lines (L2) in the middle as shown in FIG. Can be combined. The first sewing line L1 and the second sewing line L2 are both sewing lines in the longitudinal direction, and the elastic contact band 30 is sewn only in the vertical direction and not sewn in the horizontal direction so that the elastic contact band 30 is in the longitudinal direction. Can be stretched.

The distance between the first seam L1 and the second seam L2 adjacent thereto may be coupled such that the elastic tight band 30 is smaller than the fabric belt 10. That is, when the fabric belt 10 is wound around the leg, the elastic close band 30 may be in close contact with the leg.

And, because the distance between the pair of second sewing line (L2) is disposed larger than the width of the elastic band 40, the elastic band 40 when adjusting the length of the elastic band 40 through the elastic band adjuster 50 It can be easily inserted between the elastic close band 30 and the fabric belt (10).

Referring to Figures 3 and 4 will be described a method of adjusting the length of the elastic band of the elastic ankle assistor of the present invention. 4 shows an example of adjusting the length of the elastic band.

First, referring to FIG. 3, the upper fixing part of the elastic band 40 is disposed between the first support member 52 and the second support member 54. As will be described later, since the lower end of the elastic band 40 is formed asymmetrically, the elastic band 40 should be arranged to always face downward after the length adjustment.

In the case of FIG. 4, the elastic band 40 is passed upward by passing down the third support member 56, and then passed downward through the second support member 54. Then, the elastic band 40 may be reduced in length by twice the distance between the upper end of the second support member 54 and the lower end of the third support member 56. Of course, since the elastic band 40 is elastically stretched, the decreasing length is based on the length of the elastic band 40 is increased.

Unlike FIG. 4, the elastic band 40 may be passed upward by passing below the second support member 54, and then downward by passing below the first support member 52. At this time, the elastic band 40 falling down again may pass down the third support member 56 to be lowered downward.

In addition, the elastic band 40 may be passed upward by passing down the third support member 56, and then passed downward through the first support member 52 to be lowered downward.

As such, the elastic band 40 may not only be formed to have an appropriate elastic modulus and an appropriate length according to the material, but may also be applied to the appropriate elastic force by variously adjusting the length of the elastic band 40.

On the other hand, the other end of the elastic band 40, that is, the lower end preferably comprises a pocket portion 45 is inserted into the toes. The pocket 45 may be formed such that the front end of the foot can be inserted, including the toe, by cutting and sewing the elastic band as shown in FIG. 5.

The lower end of the elastic band 40 is stitched by folding about a diagonal of a square. At this time, the bottom of the elastic band 40 is to be stitched along a line perpendicular to the diagonal in order to form bluntly. The portion to be stitched in the elastic band 40 is formed with an extension so that one side edge portion can be superimposed on the other edge portion.

Here, a portion stitched perpendicular to the diagonal may be referred to as a horizontal stitching portion 41, and a portion stitched perpendicular to the horizontal stitching portion 41 may be referred to as a vertical stitching portion 43.

In other words, the bag portion 45 is a horizontal stitching portion 41 padding the first support 42 and a horizontal stitching, and a vertical stitching vertically stitching from the middle of the horizontal stitching portion with the second support 44. It is preferable to include the portion 43.

As shown in FIG. 7, when the elastic neutral ankle assistant is worn, the horizontal stitching portion 41 is disposed at the front end portion of the toe from the big toe to the middle toe, and the vertical stitching portion 43 is the horizontal stitching portion ( 41) from the middle to the center of the instep.

Since the first support 42 is a portion in contact with the front of the toes, it is preferable that the first support 42 is made of a fabric material that can be bent freely. The first support 42 can prevent the horizontal stitching portion 41 from being unwound or torn, and prevents the toes from being exhausted.

The second support 44 is preferably made of a thin bar so that the elastic band 40 can transmit the force to pull the front end of the foot in the lateral direction. The second support 44 may be made of a plastic material through which the stitching needle passes, or needle through holes may be formed in a thin plastic bar. In addition, the second support 44 may be stitched together in a padded fabric to protect the second support 44 from direct evacuation to the instep.

On the other hand, as shown in Figure 3 and 5, the elastic band 40 is gradually reduced in width from the top to the top of the bag portion 45 may be formed inclined one side. That is, as shown in Figure 5, to form the bag portion 45, the lower end of the elastic band 40 is folded along the diagonal, the left side that extends from the upper left of the diagonal to the imaginary line parallel to the right side It may be formed to be inclined at a predetermined angle (θ).

1 and 2 illustrate an embodiment in which the elastic band 40 has a constant width, but FIGS. 3 and 5 illustrate embodiments in which the elastic band 40 becomes smaller in width.

As such, when the width of the elastic band 40 is formed to become smaller and smaller, the length of the elastic band 40 can be more easily adjusted at the upper end, and the elastic band 40 is more efficient in elasticity pulling the foot laterally. Can be added.

7 shows a state in which the elastic neutral ankle assistant is worn from the foot to the leg. Figure 7 shows that the varus patient wore an elastic neutral ankle brace on the left leg.

When wearing the elastic neutral ankle assist, after adjusting the length of the elastic band 40, as described in Figure 4, the foot stitching portion 43 in the bag 45 of the elastic band 40 to the foot of the foot Insert the front end and hang it.

Thereafter, the elastic band 40 is wound around the leg while pulling in the outward direction of the foot so as to provide an elastic force for pulling the front end of the foot outward.

Subsequently, while maintaining the state of pulling the elastic band 40, the fabric belt 10 is fixed by the attachment strap 20 directly under the knee.

On the other hand, when the elastic neutral ankle assistant is worn on the right foot of the varus patient, the pocket portion 45 may be formed to be symmetrical compared to FIG. Thus, the elastic band 40 provides an elastic force in the direction to rotate the right foot outward.

And, if the valgus patient wears an elastic neutral ankle assist on the left leg, the elastic band 40 provides an elastic force to pull the front end of the foot inward.

In addition, when the valgus patient wears an elastic neutral ankle assistor on the right leg, the elastic band 40 provides an elastic force to pull out the front end of the foot.

According to the elastic neutral ankle assist device of the present invention, the structure is simple, easy to manufacture, easy to carry and very convenient to use.

Although the preferred embodiment of the present invention has been described above, the scope of the present invention is not limited only to this specific embodiment, and those skilled in the art are appropriately within the scope described in the claims of the present invention. Changes will be possible.
