  However, the tools disclosed in the above-mentioned patent documents have the following problems.

  In the devices disclosed in Patent Documents 1 to 7, all of the devices such as cushions are arranged so as to be wound or clamped from the ankle to the calf portion. In these configurations, the posture of the brace is easily shifted during posture change, turning over, or changing the rotational position of the foot, heel, or lower leg, and the pressure reducing effect of the heel cannot be obtained. Further, there is a possibility that the orthosis itself rotates and moves with respect to the ankle, and it is impossible to prevent pressure ulcers when the mounting tape portion, the binding portion, the separation portion, etc. come on the lower surface, that is, the load surface. Moreover, in these, there is no consideration for prevention of pressure ulcers and radial nerve palsy.

  In Patent Documents 8 to 11, a brace that is configured to wrap from below the knee to the toes is fixed to the leg, but the positional relationship between the brace and the ankle and ankle, and the lower leg and the brace is not always stable. If the strap is tightened to enhance stability, local pressure from the ankle to the lower leg becomes stronger, and a new pressure ulcer may occur. In the lateral position, pressure on the inner or outer heel or pressure ulcer development can be a problem.

  The cushion currently disclosed by patent documents 12-13 tries to prevent the pressure sore of the said heel part by arrange | positioning under a leg and making the heel part rise. However, all of these braces are structured like a splint that covers from the toes to above the knees, so they cannot handle the limb position when lying on the side, and there is a risk that the heel will fall off the pillow. It cannot be avoided.

  In addition, as shown in Non-Patent Documents 1 and 2, there is a risk of causing radial nerve palsy due to radial head compression in a swung limb position from the foot to the lower leg when turned into a lateral position due to turning over or changing position The problem of accompanies it has also been pointed out. For this reason, it is necessary to configure the brace so that it does not compress the ribs at a predetermined interval below the knee, and some of the braces described in the above-mentioned patent documents may cause this problem. include.

  Therefore, the technical problem to be solved by the present invention is that, even in a bedridden who is difficult to exercise spontaneously due to movement paralysis or bone joint disease of the lower limbs, limb position movement or rotation change due to body position change or rollover, Prevents heels, ankles, lower legs, radial heads and orthotics from shifting in position, prevents pressure ulcers on the heels, heels, and radial heads, and prevents radial nerve palsy, An object of the present invention is to provide a pressure ulcer prevention supporter which can be hygienically managed and can be effectively worn for the purpose of preventing edema, keeping warm and keeping cold.

  The pressure ulcer prevention supporter of the present invention provides a stretchable cylindrical cushion having a predetermined thickness from the ankle to the lower leg, via a toe, in a bedridden who is difficult to voluntarily exercise due to movement paralysis or bone joint disease of the lower limbs. Extrapolate to the top side. As a result, the heel rises from the floor surface, and the heel, which has a slightly lower protrusion than the heel, also rises from the floor surface along with the heel position by changing the posture to the lateral position or rotating the limbs. At the same time, the pressure ulcer prevention supporter covers the inner and outer upper and lower surfaces of the lower leg with appropriate load pressure or wearing pressure, so local overpressure is unlikely to occur, and the lower limb load below the knee can be received by being distributed in the calf area. Thus, pressure ulcer prevention effect is achieved.

  In addition, before installing the cylindrical cushion, an elastic cylindrical cushion cover having an ankle portion that is sewn with a relatively thin or relatively strong contractility compared to the lower leg part, via the heel, Wear extrapolated to the ankle and lower leg. At this time, the position of the cushion cover is stabilized by fitting the ankle portion of the cylindrical cushion cover to the ankle having a small diameter compared with the circumference of the user's heel or the lower leg. Next, the inner surface of the cylindrical cushion is covered by wrapping the outer surface from the openings of both ends of the cylindrical cushion by inverting the both end portions of the cushion cover ankle and the proximal portion of the lower leg. Both the outer surface and the outer surface are covered with a cushion cover, and the positional relationship between the cushion and the heel, ankle, and lower leg can be stabilized.

  In addition, the change in the pressure applied from the ankle to the calf due to the expansion and contraction of the cushion cover brings the wearing stability, and the subtle effect of changing the pressure applied in addition to the load pressure distribution by the cylindrical cushion can be applied to prevent edema. .

  In addition, by providing a relatively large number of cushion cover sizes and shapes, even if the size and shape of the cylindrical cushion itself are small, the size and shape of the physique such as the degree of calf swelling and leanness can be reduced. Adjustments for individual differences are possible.

  Here, the effect of decompressing the radial head and preventing radial nerve palsy is obtained by setting the cylindrical cushion to a length whose proximal end does not reach the radial head.

  In addition, by deforming and extending the tubular structure in accordance with the shape of the foot from the heel of the distal part of the ankle rather than the ankle, it is possible for users who are difficult to receive the load at the calf due to flexion contracture of the knee joint The load pressure on the heel can be dispersed. Then, by providing an opening in which the heel portion of the cushion material is hollowed out, the pressure relief of the heel can be obtained more reliably. Further, in order to adapt to this, good wearability can be obtained by changing the diameter of the distal part of the cushion cover from the heel according to the shape of the foot rather than the ankle part.

  In addition, by changing the color tone of the ankle portion of the cushion cover with a different color, it becomes easier to visually confirm the ankle portion when the cushion cover is mounted and the positions where the ankle portion is distal and proximal.

  Furthermore, by using a heat insulating material as the cylindrical cushion, it is expected that the heating agent or the cooling agent provided at the mounting portion of the pressure ulcer prevention supporter has a heat insulating and cooling effect.

  According to the present invention, by wearing a pressure ulcer prevention supporter, the portion beyond the calf is raised, venous perfusion is promoted, and an edema prevention effect is expected.

  The pressure ulcer prevention supporter can be freely attached and detached from the user's lower limbs, and the cushion cover and the cylindrical cushion can also be attached and detached.The cylindrical cushion is covered with the cushion cover so that it is difficult to get dirty. It can be washed and cleaned, and there are no problems with hygiene management.

  Hereinafter, the pressure ulcer prevention supporter according to each embodiment of the present invention will be described with reference to the drawings.

(First embodiment)
FIG. 1 is a view showing a state in which the pressure ulcer prevention supporter according to the first embodiment of the present invention is mounted. As shown in FIG. 1, the pressure ulcer prevention supporter 1 according to the present embodiment is used by being mounted on a user's lower limb 100. The pressure ulcer prevention supporter 1 includes a stretchable cylindrical cushion cover 2 that is extrapolated from the user's toes 101 to the ankle 103 and the lower leg 104 via the heel 102, and a cylindrical shape that is formed in a cylindrical shape that is open at both ends. A cushion 3 is provided.

  FIG. 2 is a diagram schematically illustrating a configuration of a cushion cover used in the pressure ulcer prevention supporter of FIG. 1. The cushion cover 2 is made of a cloth that is stretchable in the length direction and the radial direction, and is configured to be longer than the length of the user's lower leg 104. As the fabric used for the cushion cover 2, a woven fabric, a nonwoven fabric, a knitted fabric, and a mesh knitted fabric which are flexible and flexible and have elasticity are usable. When the cushion cover 2 is intended to be worn, the cushion cover 2 has a stretchability that can be opened to a larger diameter than the lower limbs, and the user's lower limbs are inserted through the upper opening 7a like a sock so that the heel 102 extends from the toes 101 to 102. It is mounted so as to come out from the lower opening 7b.

In addition, the cushion cover 2 is provided at a middle diameter portion of the ankle portion 4 that is elastic in the radial direction, and is positioned at both ends of the ankle portion 4 so as to be larger in diameter than the ankle portion 4 or in the radial direction. The side ends 5 and 6 are configured to be weakly stretched.

  The ankle portion 4 is intended to make it difficult for the cushion cover 2 to be displaced by tightening the user's ankle with an appropriate tightening force at the time of wearing, and generally matches the human physique. Configured. The length dimension L1 of the ankle portion 4 is preferably configured to have a width that can prevent the displacement of the cushion cover 2, and is specifically about 3 to 8 cm, and has a slight stretchability in the longitudinal direction. . In addition, the ankle portion 4 is preferably configured with a different appearance from the other parts in order to make it easy to visually recognize the mounting position to the user when worn, and specifically, the appearance of the appearance is differently colored. For example, it can be different.

  Both end portions 5 and 6 are preferably configured to be extensible so that they can be opened to a larger diameter than the lower limbs when attempting to wear, and to be extendable in the radial and longitudinal directions. In addition, the length may be different between the distal end 5 located below the ankle 103 and the proximal end 6 located above the ankle 103 at the time of wearing, for example, the distal end The length dimension L2 of the part 5 can be made shorter than the length dimension L3 of the proximal end 6.

  As will be described later, since the side end portions 5 and 6 are folded to cover and fix the surface of the cylindrical cushion 3, the radial expansion and contraction is at least the outer dimension R1 of the cylindrical cushion 3 (see FIG. 4). ) Is required to be stretchable to a greater extent.

  The tubular cushion 3 is a stretchable tubular cushion that can be extrapolated from the user's toes to the proximal lower leg via the ankles at the maximum extension, and penetrates the cylindrical main body portion 8 in the longitudinal direction. A lumen 9 is provided. The body should be made of a sponge material such as urethane molded into a cylindrical shape, a cylindrical air bag made of a stretchable urethane film, or a cylindrical cover filled with a cushioning filler. Can do.

  In addition, as a material used for the main body portion 8, by using a heat insulating material excellent in heat retaining properties (for example, foamed polyurethane, etc.), when the ankle portion is heated or cooled, the heat retaining property or the cold retaining property is maintained. Can do.

  The thickness B of the inner and outer diameter difference of the cylindrical cushion 3 is preferably larger than the difference in height between the rear surface of the user's heel 102 and the rear surface of the ankle 103. According to this configuration, the user's heel 102 when worn. The rear surface can be kept floating from the floor. Moreover, if the thickness dimension B is ensured over the entire circumference, the outer surface shape of the cylindrical cushion 3 may be a cylindrical shape or a polygonal cylindrical shape.

  Further, the outer dimension R1 of the cylindrical cushion 3 is derived from the proximal opening R3 of the lumen 9 and the thickness dimension B, and is configured to be approximately 20 to 30 centimeters.

  In the present embodiment, the lumen 9 of the cylindrical cushion 3 is configured to have the same diameter in the length direction. However, as shown in the example of FIG. The distal opening R2 may be configured to be smaller than the proximal opening R3. Further, the length dimension L4 of the cylindrical cushion 3 is preferably a length that does not reach the radial head 106 of the lower leg when worn and does not compress the radial nerve 107 that runs on the back side thereof. However, it is preferable that the length is about 30 centimeters. According to this configuration, radial nerve palsy as a complication that is likely to occur due to compression of the radial nerve 107 can be prevented.

  Next, a procedure for using the pressure ulcer supporter according to this embodiment will be described. FIG. 4 is a diagram showing a procedure for using the pressure ulcer prevention supporter of FIG. 1, and shows a state in which the cushion cover 2 is worn from the ankle 103 to the lower leg 104 via the toe 101. In order to wear the pressure ulcer prevention supporter according to this embodiment, first, the foot tip 101 is inserted into the proximal opening 7a of the cushion cover 2, and the lower limb is inserted into the lumen of the cushion cover. At this time, the ankle portion 4 of the cushion cover 2 is positioned on the ankle 103 of the user, and the approximate position is fixed. As described above, the ankle portion 4 has a relatively strong expansion / contraction force and is fastened with a certain amount of tension. Therefore, the ankle portion 4 is attached to the ankle 103, which is a thin portion of the lower limb 100, and is not easily displaced. Moreover, the anti-edema effect to a calf can be adjusted by making the change of the elasticity from the ankle part 4 to the proximal side edge part 6 via a calf part gradually.

  Next, as shown in FIG. 5, the cylindrical cushion 3 is extrapolated to the lower limb. FIG. 5 schematically shows a state in which the cylindrical cushion 3 is extrapolated and worn on the cushion cover 2. The cylindrical cushion 3 is inserted such that the lower limb 100 with the cushion cover covered in the inner cavity 9 is positioned so that the heel portion is typically the distal opening 9a. At this time, the radial head 106 is preferably located outside the proximal opening 9b. The positioning can be performed by appropriately adjusting the cushion cover 2 according to the length dimension of the cylindrical cushion 3 and the length of the user's lower leg. Accordingly, the pressure ulcer prevention supporter 1 according to the present embodiment can be mounted by adjusting and fixing the fixed state of the cylindrical cushion 3 with the cushion cover 2, so that even users of various physiques can use the cushion cover. By preparing a plurality of sizes and shape types, there is an advantage that the size and type of the cylindrical cushion itself can be reduced.

  Next, as shown by an arrow 90 in FIG. 5, the side ends 5 and 6 of the cushion cover 2 exposed to the outside of the aligned cylindrical cushion 3 are folded back. The side ends 5 and 6 folded back as described above are fixed by being placed on the outer surface 10 of the aligned cylindrical cushion 3. As described above, the cushion cover 2 is positioned on the user's lower limb by the ankle portion 4, and the both end portions 5 and 6 are folded back so as to cover the outer surface from both end openings 9 a and 9 b of the cylindrical cushion 3. As shown in FIG. 6, the two are combined, and the cylindrical cushion 3 is disposed around the lower leg 104. By arranging in this way, the inner surface 9 and the outer surface of the cylindrical cushion 3 are both covered with the cushion cover 2, and the pressure ulcer prevention supporter 1 having a stable positional relationship with the heel, ankle, and lower leg is worn. Complete.

  According to the pressure ulcer prevention supporter 1 according to the present embodiment, as shown in FIG. 7 and FIG. 8, the heel portion is arranged in a state of being lifted from the floor surface 102a in the supine state, thereby preventing pressure ulcers in the heel portion. it can. Further, even when the person is in a lying position due to turning over or the like, since the part of the heel 108 is lifted from the floor surface, the pressure ulcer on the part of the heel 108 can also be prevented. At the same time, the pressure ulcer prevention supporter covers the inner and outer upper and lower surfaces of the lower leg with appropriate pressure, so local overpressure is unlikely to occur, and the lower limb load below the knee will be received by pressure distribution in the calf part, A pressure ulcer prevention effect is achieved. Further, the radial head 106 also floats in the lateral position, avoiding the compression of the radial nerve 107 and preventing the radial nerve paralysis.

  As described above, according to the pressure ulcer prevention cover 1 according to the present embodiment, it is easy to wear, for example, in a nursing treatment performed in a hospital or the like, without spending the time required for wearing, and effectively, Pressure ulcers can be prevented.

  The pressure ulcer prevention supporter 1 according to the first embodiment is mounted in a state where the heel portion 102 is exposed from the cylindrical cushion 3 and is held in a state where the heel 102 is lifted, but the posture is such that the knee joint is straight. Limited to certain cases. The cylindrical cushion 23 according to the present embodiment is mounted so that the heel 102 is accommodated in the cushion 23 so that the heel 102 is not in direct contact with the floor surface so that it can cope with knee joint flexure contracture. is there.

  For this purpose, the cylindrical cushion 23 is configured to match the shape of the lumen 99 with the shape of the heel and heel to the tip of the foot. Specifically, a recess 24 for accommodating the heel 102 is provided in the vicinity of the distal opening 29 a of the lumen 29.

  The cylindrical cushion 23 according to this embodiment is attached so that the attachment position with the cushion cover 2 is slightly shifted downward and the heel 102 at the distal portion of the ankle is disposed in the recess of the cylindrical cushion 23. With this configuration, a cushion can be disposed on the heel 102 to prevent pressure sores, and even when the knee joint is in a slightly bent position, the crus 104 is supported and the heel 102 is supported. The pressure ulcer can be prevented without applying pressure to the skin.

  As a modification according to the present embodiment, as shown in FIG. 10, the same effect can be obtained by providing a through hole 25 in a part of the main body portion 23 b of the cylindrical cushion 23 a instead of the recess 24.

The main body 31 of the supporter has elasticity so that when the lower limb is inserted into the lumen 32 and the leg is placed on the floor at the time of wearing, the support body 31 is deformed by its own weight and changes to the shape of the lower limb. On the other hand, it is preferable that the thickness dimension B is maintained to be larger than the height difference between the rear surface of the user's heel 102 and the rear surface of the ankle 103 even after deformation due to the weight of the lower limb.

  Further, the lumen 32 is configured such that the diameter R3 of the proximal opening 32b is larger than the diameter R2 of the distal opening 32a in order to have a shape along the user's lower limb when the user's lower limb is inserted. Furthermore, it is preferable that the diameter is gradually reduced toward the distal side. In addition, the distal opening 32a is preferably configured to be smaller than the cross-sectional diameter of the user's lower limb including the user's heel or inner / outer buttock when contracted. Thus, problems such as displacement can be prevented by tightening on the lower limbs. In addition, the diameter change from the diameter R2 to the diameter R3 may be multimodal depending on the shape of the calf, and the edge corners of the distal opening 32a and the proximal opening 32b are A blunt shape is preferred to soften contact with the skin surface.

  Note that the inner surface of the lumen 32 may be covered with, for example, an inner patch such as a pile fabric in order to enhance the tactile sensation when contacting the lower limb.

(Fourth embodiment)
