Description

  The present invention is a wearing device for compression such as a bandage, a supporter, a sleeve, a stocking, an underwear made of a stretchable fabric as a whole used in a compression method (such as wearing elastic stockings) that compresses a part of a human body, In particular, a medical device that can be used as a supporter for lymphedema treatment or a varicose vein support, or an elastic bandage that applies external pressure to the arm, leg, head, foot, hand, etc. The present invention relates to an elastic cylindrical bandage that can be used to improve and prevent edema of a limb trunk by applying a compressive force to a necessary part of the limb trunk.

As a known supporter for treating lymphedema, there is a technique described in Patent Document 1.
Patent Document 1 is a leg supporter for treating lymphedema that can be worn with a velvet fastener that covers from the ankle to the thigh while adjusting the pressure applied to the leg. In the leg supporter for treating lymphedema of Patent Document 1, two fabrics covering the inner and outer surfaces of the leg from the buttocks to the thigh are substantially matched to the leg curve at the rear center of the leg. It is a flat thing formed by wearing, and these two pieces of cloth are made of a stretchable material (stretch material made of elastic fiber), and the first and second cloths have a recess in the front knee. And the upper part and the lower part of the knee part are formed so as to overlap each other on the front surface when the supporter is attached to the leg, and the raised cloth is placed on the front surface of the first cloth. In a state where the velvet fastener (surface fastener) is attached to the back surface of the front portion of the second fabric and the velvet fastener is locked to the raised cloth, the knee head is shown. Ankle to thigh Whole overlying will not disclose the techniques that can be mounted.

In Patent Literature 1, when the ankle to thigh are covered with a velvet-type fastener, a single-wrapped portion and a double-wrapped portion are formed, and there is a sense of incongruity. Further, if the muscle moves during use, the tightening force varies, and the tightening cannot be maintained by the uniform tightening force. And in the site | part wound twice, air permeability cannot be ensured, but it sweats partially, and depending on the case, dermatitis may be caused and it may become itchy.
Therefore, in Patent Document 2, the bandage-shaped compression cloth material, the first surface of the compression cloth material, and the second surface opposed to the bandage-shaped compression cloth material can be releasable at a plurality of locations in the length direction of the compression cloth material. There is disclosed a medical device that applies a compression force to a limb trunk having locking means for locking to the limb.
According to this medical device, since the compression cloth material is in a bandage shape, it is easy to wrap the compression cloth so as to give a desired compression force to the extremities of the human body. The first surface and the second surface of the compression cloth material can be locked. Therefore, with respect to the human body part once wound, the pressing cloth material does not fall off from the human body even if the user releases his / her hand from the pressing cloth material, and the locking means can be freely released. The first surface and the second surface can be locked, and the winding can be easily performed again.

In particular, in Patent Document 2, the locking means is constituted by a male surface fastener and a female surface fastener respectively provided on the first surface and the second surface of the compression cloth material, and has a simple structure. The first surface and the second surface are releasably locked. Further, one of the male surface fastener and the female surface fastener is provided so as to extend over the length of the portion of the compression cloth material wound around the human body, and the other of the male surface fastener and the female surface fastener. However, a plurality of male surface fasteners and female surface fasteners are released to any one of the male surface fasteners and female surface fasteners. It can be freely locked.
Therefore, patent document 2 has the characteristics that even if there is no specialized technique, it can prevent slipping and can easily obtain an appropriate compression force.

This makes it difficult to reduce the compression force even if the muscle moves during use. However, when a pair of male surface fasteners and female surface fasteners are close to each other, when the thickness of the compression cloth material is overlapped and wound, a half overlap of the compression cloth material and the male surface fastener and the female The overlap of mold surface fasteners is added, and the effect of measures against ventilation does not occur. Moreover, in patent document 2, the freedom degree of a knee joint is lose | eliminated and it feels inconvenience by being wound on the said compression cloth material. Moreover, when the space | interval of the pair of the said male type | mold fastener and the said female type | mold fastener is widened, the situation where the winding force as required compression force cannot be obtained is assumed.
In the compression method, it is necessary to apply an appropriate compression force (for example, 5 to 60 mmHg) to the affected area (swelling) region by applying a dedicated wearing tool such as a compression bandage to these items. It is very difficult to adjust to the appropriate pressure according to the swelling and patient condition. This is described in Patent Document 3.

In Patent Document 3, the pressing time and the interval between the pressed parts in the affected area are also important for symptom improvement, but it is very difficult to set them optimally. For example, when inappropriate pressure (specifically, uniform and / or excessive pressure) is applied, the opposite effect (specifically, vein or lymphatic vessel occlusion, capillary leakage, lymphatic fluid migration, etc.) Symptom) and symptoms worsen. Thus, it is pointed out that it is necessary to leave it to an expert, a doctor, or a nurse when wearing a compression bandage or the like because precise control of pressure is difficult.
Furthermore, in Patent Document 3, when using a mounting tool such as a supporter, a sleeve, a stocking, an undergarment, etc., which is preliminarily molded according to the shape of the mounting part and can be adjusted to a desired pressure, it is attached and detached. He points out that there are difficulties and that the wearing feeling and the feeling of use are poor. In addition, for example, when a pair of compression stocking-like wearing devices are manufactured separately on the left and right under an appropriate design corresponding to the swelling of each foot, the problem that the cost of the wearing device increases is also pointed out. .

At present, there are no effective drugs for lymphedema, and the treatment is left to physical therapy. However, as described above, Patent Document 1 has a sense of incongruity for a user in a region where a compression material for treatment is wound in a single layer and double, and when muscles are active during use, uniform tightening is performed. The tightening cannot be maintained by the applied force. Not only that, air permeability cannot be secured at the portion wound twice.
Further, although Patent Document 2 can be worn without proper technical force without proper technical force, the male hook-and-loop fastener and female If the distance between the pair of mold surface fasteners is narrow, the degree of freedom of the knee joint is lost and inconvenience is felt. Moreover, if the space | interval of the pair of the said male type | mold fastener and the said female type | mold fastener is widened, required winding force will not be obtained.
In Patent Document 3, the pressing time and the interval between the pressed parts in the affected area are also important for symptom improvement. However, it is very difficult to set these optimally, and improper pressure is applied. If this happens, the opposite effect may occur and the symptoms may worsen. In addition, it is necessary to apply an arbitrary pressure to the affected area, but there is a need for a method that can be worn without leaving it to a skilled person, doctor, or nurse.

  Therefore, the present invention eliminates the problems pointed out in Patent Document 1 to Patent Document 3, provides a good feeling of wearing and feeling of use, and can receive a well-balanced pressing force during use. At times, there is no sense of incongruity, the user's movement does not unwind and the position does not move, and even if you are not an expert, you can easily attach and detach by applying a specific pressure in the mounting direction. An object is to provide an elastic cylindrical bandage having air permeability.

It said base is the body peripheral length information to the length direction of the site to be human body mounting _{(m 1, m 2, m} 3, ···) in accordance with, the seamless knit flat knitting machine according to the length A whole garment knitting machine (Whole garment is a registered trademark of Shima Seiki Seisakusho Co., Ltd.) is used to determine the shape of the full length of the wale by specifying an annular stitch density, Young's modulus E, and number of stitches. In addition, the inventor used MACH2X, MACH2S, and SWG of the whole garment flat knitting machine manufactured by Shima Seiki Seisakusho Co., Ltd. as the whole garment knitting machine.
Further, the auxiliary fixing portion is formed by forming a knitted fabric with less elasticity by increasing the number of stitches sequentially or at a time from the base to the direction side close to the heart, and has no strong tightening force. The pressing force due to the tightening of the abutting part is felt strongly, and there is no irritation and no irritation.

Further, the base portion, the auxiliary fixing portion, and the cutting portion are knitted by one spun yarn, the spun yarn is folded back on the auxiliary fixing portion side, and the start end and the end end of the spun yarn are positioned on the cutting portion side. To do.
Note that one spun yarn is specifically recognized as one spun yarn by garment knitting of a non-sewn knit flat knitting machine. In addition, the yarn is not limited to spun yarn, and filament yarn, monofilament yarn, bulky yarn, hollow yarn, coated yarn, core yarn yarn, composite yarn, flat yarn, irregular cross-section yarn, split yarn, lacquer yarn, etc. can be used. It is. The raw material of the yarn can be a yarn formed from a chemical material, a yarn formed from a metal, a yarn formed from a plant, a twisted yarn composed of a combination of two or more thereof, and in particular, mechanical. Even if the strength is high, the knitting method is given elasticity, and therefore it is desirable to use a material having a relatively high mechanical strength such as a tensile strength that is difficult to cut. Further, the knitting method may be a rib knitting, a mesh knitting, a pattern knitting or the like, and if necessary, a stretch knitting, a bare knitting, or a pearl knitting.

Further, the auxiliary fixing portion is formed by forming a knitted fabric with less elasticity by increasing the number of stitches sequentially or at a time from the base to the direction side close to the heart, and has no strong tightening force. The pressing force by tightening the abutting part is felt strongly, causing no irritation and no irritation.

Further, the base portion, the auxiliary fixing portion, and the cutting portion are knitted by one spun yarn, the spun yarn is folded back on the auxiliary fixing portion side, and the start end and the end end of the spun yarn are positioned on the cutting portion side. To do.

On the side of the elastic cylindrical bandage according to the present invention attached to the human body, there is a Young's modulus E on the wale side of the stitch row in which the spun yarn is knitted in an annular shape, and between the stitch rows in which the spun yarn is knitted in an annular shape. The relationship with the Young's modulus E ₀ on the course side is E ≧ E ₀ .
Here, a one-ring Young's modulus E on the wale side of the stitch row in which the spun yarn is knitted in an annular shape and a Young's modulus E ₀ on the course side between the stitch rows in which the spun yarn is knitted in an annular shape are the same. If there, both elongation is the same, easily pulling direction to be attached to the human body and the E> E _0. On the other hand, when E <E _0, it becomes difficult to handle because only the tension changes in the direction of mounting on the human body. Therefore, it is preferable that the Young's modulus E ₀ between the stitch rows in which the spun yarn is knitted in an annular shape is smaller than the Young's modulus E in the stitch row in which the spun yarn is knitted in an annular shape.

The elastic cylindrical bandage according to claim 1 is the human body position information (L ₁ , L ₂ , L ₃ ,...) In the length direction to be worn on the human body and the human body position information (L ₁ , L ₂ , L _3). ,...), An elastic cylindrical bandage to be worn in the wale length direction of a part of the human body, which is knitted as the perimeter length information (m ₁ , m ₂ , m ₃ ,...) In the human body circumference information (m ₁ , m ₂ , m ₃ ,...), The stitch density and Young's modulus E are fixed and set to approximate number of stitches.
Therefore, since the elastic cylindrical bandage of the present invention has a constant Young's modulus E, that is, the elongation of the circumference of the human body of the knitting row on the wale side in which the spun yarn is knitted in an annular shape can be made constant, the user is always elastic. A uniform compression force can be received from the entire cylindrical bandage.
In addition, since the stitch density of the elastic cylindrical bandage of the present invention is made constant and the number of annular stitches is variable, the physical properties of the fabric are measured, and the pressure distribution is determined by setting the number of stitches that approximates its Young's modulus E The elastic cylindrical bandage that is worn in the length direction of a part of the human body can respond to changes in the cross section of the human body even when the cross sectional shape of the human body differs from the length, such as legs and arms By changing the stitches, the entire wearing part is uniformly compressed, and it is possible to apply a custom-made compression force according to an individual case. Of course, it is also easy to create a standard that is a standard product from the user's data and the national average figure.
And since the elastic cylindrical bandage need only be worn against the elasticity in the length direction of a part of the human body, if an arbitrary pressure is applied to the length direction of a part of the human body without being an expert, If pressure is applied in the right-angle direction as needed, it is free to attach and detach, is easy to handle and carry, and has a single base that applies compression force. Is good. And since the elastic cylindrical bandage of this invention is knitted by the cylinder shape, winding cannot be unwound by a user's exercise | movement or the position to which it has mounted | worn does not move.

In this way, since the stitch density can be made constant, if the physical properties of the fabric are measured and the Young's modulus E is determined by determining the increase / decrease in the number of stitches, the pressure distribution can be stabilized at a desired value. In addition, since the number of annular stitches is determined by a non-sewn knit flat knitting machine and the shape of the entire length is determined, the end of a single spun yarn becomes one end, so that the entire management becomes easy.
Furthermore, since the elastic cylindrical bandage of the present invention is single, and the stitch density can be arbitrarily set by setting the number of stitches, the countermeasure for ventilation is perfect.
Therefore, the wearing feeling and the feeling of use are good, there is no sense of incongruity due to a well-balanced pressing force at the time of use, the wearing state is not released by the user's movement, and the movement of the position does not occur, Even if it is not an expert, it can be attached and detached without difficulty by applying a specific pressure, and air permeability can be secured.

The present invention, the body position information of the length direction of the part of the body is mounted object _{(L 1, L 2, L} 3, ···) and said human body position information _{(L 1, L 2, L} 3 ,...), An elastic cylinder mounted in the length direction of a part of the human body knitted using the perimeter information (m ₁ , m ₂ , m ₃ ,...) The human body perimeter information (m ₁ , m ₂ , m ₃ ,...) Has a constant stitch density and Young's modulus, a base set to an approximate number of stitches, stitch density and Young A fixed rate and an auxiliary fixing part set to an approximate number of stitches, and a plurality of fraying stoppers formed on the opposite side of the base to the auxiliary fixing part are arranged in an annular shape, and the stitches are formed from the base to the side closer to the heart. Human body perimeter information (m ₁ , m ₂ , m ₃ ,...) In which a small number of elastic knitted fabrics are formed in a ring shape. The stitch density and the Young's modulus are fixed, set to an approximate number of stitches, and have a cutting part that can be cut freely. The base part, the auxiliary fixing part, and the cutting part are knitted by one spun yarn. is there.

Therefore, the elastic tubular bandage of the present invention can always maintain the Young's modulus E on the wale side at a constant value, and the elongation of the circumference of the body of the waled stitch row in which the spun yarn is knitted in an annular shape can be made constant. The user can receive a uniform compression force from the entire bandage.
Further, since the stitch density of the elastic cylindrical bandage of the present invention is made constant and the number of annular stitches is variable, the physical properties of the fabric are measured, the Young's modulus E is selected, and the pressure is set by setting the number of stitches. The elastic cylindrical bandage that can be evenly distributed and worn in the length direction of a part of the human body can change the cross-section of the human body even when the cross-sectional shape of the human body with respect to the length is different, such as legs and arms. Correspondingly, the stitches are changed, and the entire body is uniformly compressed, and it is possible to apply a custom-made compression force according to an individual case. Of course, it is also easy to create a standard that is a standard product from the user's data and the national average figure.

The elastic cylindrical bandage according to the present invention may be attached in the length direction of a part of the human body, so even if it is not an expert, any pressure may be applied in the length direction of a part of the human body. Is easy to handle and carry, and since the base portion to which the pressing force is applied is formed in a single layer, the feeling of wearing and feeling of use are good. And since the elastic cylindrical bandage of this invention is knitted by the cylinder shape, winding cannot be unwound by a user's exercise | movement or the position to which it has mounted | worn does not move.
In this way, since the stitch density can be made constant, if the physical properties of the fabric are measured, and the Young's modulus E is determined by determining the increase / decrease in the number of stitches, the pressure distribution receiving the compression force can be stabilized to a desired value. Can do. In addition, since the number of annular stitches is determined by a non-sewn knit flat knitting machine and the shape of the entire length is determined, the end of a single spun yarn becomes one end, so that the entire management becomes easy.
Furthermore, since the elastic cylindrical bandage of the present invention is single, and the stitch density can be arbitrarily set by setting the number of stitches, the countermeasure for ventilation is perfect.

In addition, since the cutting portion is provided with a plurality of rows of fray stoppers formed on the opposite side of the auxiliary fixing portion of the base so as to be freely cut, for example, a standard based on compression force. When created, the cutting part can be resized according to the user's body, and can be selected based on the compression force, which is an important factor for the user, and the length of the leg or arm. Since it suffices to cut according to the situation, it is not necessary for the user to prepare special knowledge. Further, the elastic cylindrical bandage of the present invention is formed by one spun yarn, but is cut at the end side of the spun yarn, so that the mechanical strength is reduced by partial cutting. There is no.
In addition, the auxiliary fixing portion is a body circumference information (m ₁ , m ₂ , m ₃ ,...) Of a part to be worn in the length direction of a part of the human body with respect to the length direction of the part of the human body. ), The number of stitches is increased in the direction closer to the heart from the base portion formed by specifying the number of annular stitches, and a less elastic knitted fabric is formed in an annular shape. Since the elastic force is weaker than that of the base portion, the elastic cylindrical bandage of the present invention does not move without permission while maintaining an elastic force that maintains its position without biting into a part of the human body.
Therefore, the wearing feeling and the feeling of use are good, there is no sense of incongruity due to a well-balanced pressing force at the time of use, the wearing state is not released by the user's movement, and the movement of the position does not occur, Even if it is not an expert, it can be attached and detached without difficulty by applying a specific pressure, and air permeability can be secured.

And since it is only necessary to attach the elastic cylindrical bandage in the length direction of a part of the human body, even if it is not an expert, it is sufficient to apply arbitrary pressure to the length direction of a part of the human body, and it can be freely attached and detached. It is excellent in handling and carrying convenience, and since the base portion for applying a pressing force is formed in a single layer, the feeling of wearing and feeling of use are good. And since the elastic cylindrical bandage of this invention is knitted by the cylinder shape, winding cannot be unwound by a user's exercise | movement or the position to which it has mounted | worn does not move.
In this way, since the stitch density can be made constant, if the physical properties of the fabric are measured, and the Young's modulus E is determined by determining the increase / decrease in the number of stitches, the pressure distribution receiving the compression force can be stabilized to a desired value. Can do. In addition, since the number of annular stitches is determined by a non-sewn knit flat knitting machine and the shape of the entire length is determined, the end of a single spun yarn becomes one end, so that the entire management becomes easy.
Furthermore, since the elastic cylindrical bandage of the present invention is single, and the stitch density can be arbitrarily set by setting the number of stitches, the countermeasure for ventilation is perfect.

In addition, since the cutting portion is provided with a plurality of rows of fray stoppers formed on the opposite side of the auxiliary fixing portion of the base so as to be freely cut, for example, a standard based on compression force. When created, the cutting part can be resized according to the user's body, and can be selected based on the compression force, which is an important factor for the user, and the length of the leg or arm. Since it suffices to cut according to the situation, it is not necessary for the user to prepare special knowledge. Further, the elastic cylindrical bandage of the present invention is formed by one spun yarn, but is cut at the end side of the spun yarn, so that the mechanical strength is reduced by partial cutting. There is no.
Further, the auxiliary fixing part is formed by specifying the number of annular stitches according to the human body perimeter information with respect to the length direction of the part of the human body at the part to be worn in the length direction of the part of the human body. The knitted fabric with less elasticity is formed in an annular shape by increasing the number of stitches from the base to the side closer to the heart, and in particular, the auxiliary fixing part is less elastic than the base, On the other hand, the elastic force that maintains the position is maintained without biting in, and the elastic cylindrical bandage of the present invention does not move without permission.
Therefore, the wearing feeling and the feeling of use are good, there is no sense of incongruity due to a well-balanced pressing force at the time of use, the wearing state is not released by the user's movement, and the movement of the position does not occur, Even if it is not an expert, it can be attached and detached without difficulty by applying a specific pressure, and air permeability can be secured.

In addition, the cutting part is provided with a plurality of fraying stoppers formed on the side of the base opposite to the auxiliary fixing part in a ring shape so that it can be cut. For example, a standard is created based on the compression force. In this case, the size can be changed by the cutting part, and it is selected based on the compressive force that is an important factor for the user for use, and cut according to the length of the leg or arm. As a result, it is not necessary for the user to prepare special knowledge. Further, the elastic cylindrical bandage of the present invention is formed by one spun yarn, but is cut at the end side of the spun yarn, so that the mechanical strength is reduced by partial cutting. There is no.
In addition, the auxiliary fixing portion is a body circumference information (m ₁ , m ₂ , m ₃ ,...)

[Embodiment]
FIG. 1 is a plan view of a long one-leg supporter.
The positions of the human body position information L ₁ , L ₂ , L ₃ ,..., L ₆ , L ₇ as the leg length of the human body are determined as the positions of the dimensions to be measured as shown in Table 1. Therefore, depending on the use, pressure is applied from the outside, such as the supporter type, sleeve, stockings, underwear, supporter for lymphedema treatment or varicose veins, or the arm, leg, head, foot, hand, etc. The position to be measured is determined by the type of the elastic cylindrical bandage, and the circumference of the position is measured. However, in this embodiment, Table 1 is a numerical value as an embodiment, and is not directly related to the elongation shown in FIG.

The elastic cylindrical bandage of the present embodiment is an example in which the whole or only the base 10 is set to an approximate number of stitches with a constant stitch density and Young's modulus.
When the human body position information L ₁ , L ₂ , L ₃ ,..., L ₆ , L ₇ is determined according to the use, one circular stitch row in which spun yarn is knitted in an annular manner at the position, that is, an elastic cylinder In the following, the annular stitch row of the bandage is measured as the “wel side”. In addition, the row of loops arranged in the vertical direction of the knitted fabric is referred to as a course side, and the row of loops arranged in the horizontal direction is referred to as a wale side.
That is, when the position of the human body in the length direction, that is, the position information L ₁ , L ₂ , L ₃ ,... Changes, the corresponding body position information L ₁ , L ₂ , L ₃ ,. Corresponding to the body length information m ₁ , m ₂ , m ₃ ,... Corresponding to the thickness of the leg or arm. The human body perimeter information m ₁ , m ₂ , m ₃ ,... Can calculate the number of stitches based on the calculation result obtained by calculating the knit density and Young's modulus E on the wale side as uniform. As a result, the perimeter information m ₁ , m ₂ , m ₃ ,... Has a constant Young's modulus E on the wale side, and the number of stitches can be calculated.

When the positions of the human body position information L ₁ , L ₂ , L ₃ ,... As the leg length change, the human body perimeter information m ₁ , m ₂ , m ₃ ,. When the cross section of the part worn on the human body changes, the length on the wale side may change accordingly, but the Young's modulus E does not change. That is, the human body position information L ₁ , L ₂ , L ₃ ,... Of a part of the human body to be worn, and the human body position information L of one annular stitch row in which spun yarns are knitted in an annular shape. _The information of the elastic cylindrical bandage is measured using the human body perimeter information m ₁ , m ₂ , m ₃ ,... Of the perimeter in the vertical section with respect to ₁ , L ₂ , L ₃ ,.
Incidentally, the body position information _{L 1, L 2, L 3} , ···, L 6, L 7 is set the measuring point part there is a change in body shape or before and after.

However, the human body perimeter information m ₁ , m ₂ , m ₃ ,... With respect to the human body position information L ₁ , L ₂ , L ₃ ,. However, in this state, the one-round human body circumference information m ₁ , m ₂ , m ₃ ,... Is the circumference of the vertical section with respect to the human body position information L ₁ , L ₂ , L ₃ ,. It means that.
Therefore, the Young's modulus E on the wale side of the spun yarn used is calculated.

That is, the wale side calculated from the human body perimeter information m ₁ , m ₂ , m ₃ ,... With respect to the human body position information L ₁ , L ₂ , L ₃ ,. Represents the number of eyes. This calculation result calculates the number of scales, but the unit below the scale may be rounded off, rounded down, or rounded up. This selection of rounding, rounding up or rounding off can be determined by the physical properties of the spun yarn and the characteristics of the use of the elastic cylindrical bandage.
The Young's modulus E is that the cross-sectional area of the knitting on the wale side (physical property of the spun yarn) is S, the force applied to the cross-sectional area of the monocyclic knitting (physical property of the spun yarn) S is F, and the original length P is ΔP. When stretched
E = (F / S) / (ΔP / P)
It is represented by Here, F / S becomes a constant as a result. That is, the cross-sectional area S of the knitted yarn on the wale side is determined from the physical properties and the knitting method of the spun yarn, and the force F applied to the cross-sectional area (physical property of the spun yarn) S of the knitted yarn on the wale side is always constant at any place. Since it is desired to be a value, it becomes a fixed value, and F / S is a constant.

1 and 2 show the measurement of the relationship between the length information m ₁ , m ₂ , m ₃ ,..., M ₆ , m ₇ of the length. It is to be worn on the human body leg (part).
That is, the human body position information L ₁ , L ₂ , L ₃ ,..., And the human body perimeter information m ₁ , m ₂ , m ₃ ,. -It is an elastic cylindrical bandage that is knitted using and attached in the length direction of a part of the human body.
This is based on the human body circumference information m ₁ , m ₂ , m ₃ ,... Of the vertical section relative to the human body position information L ₁ , L ₂ , L ₃ ,. It can be set as the base 10 shown in FIG. 1 which set the number of eyes approximated so that it may become the calculation result which calculated E.

Further, the auxiliary fixing portion 20 in which the number of stitches is increased from the base portion 10 to the direction side close to the human heart and the knitted fabric with less elasticity is formed in an annular shape is at the top of the long one-leg supporter of the present embodiment, When the end portion is suddenly generated at 10, the Young's modulus E on the wale side is not affected by the adjacent unit, and there is a possibility that several times the elastic force is directly applied to the thigh. When used in such a state, the blood circulation is deteriorated due to individual differences, and the thigh which hits the end of the base 10 may be tightened and may become red or ugly.
Therefore, the auxiliary fixing portions 20 subsequent to the unit adjacent to the end portion of the base portion 10 are configured to sequentially decrease the Young's modulus E. Moreover, even if it bend | folds double, elasticity is made not to change a lot. As a result, the circulation of blood is not deteriorated, and the elasticity of the thigh hitting the end of the base portion 10 does not increase, and conversely, it does not become red or ugly.

Then, the cutting unit 30 which is freely cut with loose stopper that is arranged in a plurality annular opposite the auxiliary fixing portion 20 of the base 10 has a body peripheral length information m ₇ of perimeter around the ankle L ₇ The distance between the human body position information L _{1 to} L ₇ varies depending on the leg length of the person who uses it.
Therefore, in the present embodiment, during the production of the elastic cylindrical bandage, a synthetic resin adhesive is injected into one spun yarn to be supplied and applied to the spun yarn knitting the cutting portion 30. Is.
Further, the fraying prevention method can be formed by applying a synthetic resin adhesive in addition to the spun yarn for knitting the cutting portion 30.
Body position information L ₈ of Figure 1, the ring coated with synthetic resin adhesive double is formed in three places. That is, the human body position information L ₈₁ is formed of the human body position information L _81a and L _81b , the human body position information L ₈₂ is formed of the human body position information L _82a and L _82b , and the human body position information L ₈₃ is the human body position information L _83a , L _83b . Therefore, it is desirable to cut between the human body position information L _81a and L _81b with a scissors. Of course, the human body position information L _81, L _82, L _83, etc. may be formed in a single layer or a predetermined width.

Here, the base part 10, the auxiliary fixing part 20 and the cutting part 30 are knitted by one spun yarn, the spun yarn is folded back on the auxiliary fixing part 20 side, and the start end and the end of the spun yarn are cut parts. In the case of the one located on the 30th side, only one spun yarn needs to be processed, so that no fraying occurs.
Further, the base 10, the auxiliary fixing part 20, and the cutting part 30 are knitted by a single spun yarn, the spun yarn is folded back on the cutting part 30 side, and the start and end ends of the spun yarn are the auxiliary fixing part. Since the free end portion of one spun yarn is restrained by the cutting portion 30 in the one located on the side, fraying does not occur.
In any case, the base 10, the auxiliary fixing portion 20, and the cutting portion 30 are knitted by one spun yarn, the spun yarn is folded back on the auxiliary fixing portion 20 side, and the start end and the end of the spun yarn are cut. Since it is located on the part 30 side, fraying does not occur and the life can be extended.

FIG. 2 (a) is a measuring list of elastic cylindrical bandages as long leg supporters for legs, and FIG. 2 (b) is a pantyhose-shaped elastic cylindrical bandage for measuring the elastic cylindrical bandages of this embodiment. It is a measuring list.
These are not only measuring long one leg supporters, pantyhose, long stockings, high socks, girdle, but also knee supporters, ankle supporters, calf supporters, waist supporters, elbow supporters, etc. As a cylindrical bandage, they are basically the same, so only two cases are described.

If a measurement of the long leg supporter of the present embodiment shown in FIG. 2 (a), performing the measurements of ankle L ₈ from the groin L ₁ of the human body.
The positions of the human body position information L ₁ , L ₂ , L ₃ ,..., L ₆ , L ₈ as the leg length of the human body are specified. The dimensions around the legs at the positions of the specified human body position information L ₁ , L ₂ , L ₃ ,..., L ₆ , L ₈ are measured and recorded.
First, to measure the body peripheral length information m ₁ of the perimeter around the groin L _1. Next, to measure the body circumference length information m ₂ of the circumferential length around the center of the thigh L _2. The body circumference information m ₃ and m ₄ of the circumference around the vertical positions L ₃ and L ₄ of the knee is measured. Human body circumference information m ₅ , m _6, m ₇ of the circumference around the upper and lower positions L ₅ , L ₆ , L ₇ of the shin and calf is measured. Then, to measure the body circumference length information m ₈ of the perimeter around the ankle L _8.

Of the pantyhose type elastic cylindrical bandage and human body perimeter information m ₁ , m ₂ , m ₃ ,. The relationship is acquired.

Next, in FIG. 3, an outline comparison is made between the elastic cylindrical bandage according to the embodiment of the present invention and a conventional elastic stocking sold in a foreign country.
In the embodiment of the present invention, the overall stitch density and Young's modulus are constant, and the number of stitches (number of stitches) is changed. Further, as a conventional example, the elastic stockings (b) commercially available in foreign countries have the stitch density changed, the thigh has a coarse stitch density, and the ankle has a fine stitch density.

When the stitch density is changed without changing the conventional stitch number shown in FIG. 3B, the number n of the wales is constant, and the position in the length direction of the human body, that is, the human body position information L ₁ , When the positions change as L ₂ , L ₃ ,..., The corresponding positions are determined according to the human body perimeter information m ₁ , m ₂ , m ₃ ,. The This elongation is the sum of an elastic change component and a quantitative component.
That is, the change in the conventional example is Y = aX + B, and the quantitative component B, which should be a constant term, and the proportional multiplier a are always variables, so that the human body perimeter information m ₁ , m ₂ , m ₃ ,. The elasticity will change accordingly.

On the other hand, in the embodiment of the present invention shown in FIG. 3A, the stitch density is constant and the number of stitches is changed. Therefore, the number of stitches is set so that the Young's modulus E on the wale side becomes a constant value. The approximate number of eyes can be set so that the calculated result is obtained.
That is, when the position changes with the human body position information L ₁ , L ₂ , L ₃ ,... In the length direction of the human body, the corresponding positions make the entire stitch density uniform, and the human body position information L ₁ , Corresponding to L ₂ , L ₃ ,..., Human body perimeter information m ₁ , m ₂ , m ₃ ,. The human body perimeter information m ₁ , m ₂ , m ₃ ,... Can calculate the number of stitches based on the calculation result of calculating the stitch density and Young's modulus E on the wale side. As a result, the human body perimeter information m ₁ , m ₂ , m ₃ ,... Is expressed as the Young's modulus E on the wale side and the number of stitches.

When the position of the human body position information L ₁ , L ₂ , L ₃ ,... As the leg length changes, the body circumference information m ₁ , m ₂ , m ₃ ,. . When the cross section of the part worn on the human body changes, the length on the wale side changes accordingly, but its Young's modulus E does not change. That is, the human body position information L ₁ , L ₂ , L ₃ ,... Of a part of the human body to be worn and the human body position information L of the waled stitch row in which the spun yarn is knitted in an annular shape ₁ , L ₂ , L ₃ ,... In the length direction of a part of the human body knitted using the human body perimeter information m ₁ , m ₂ , m ₃ ,. An elastic cylindrical bandage, and the human body perimeter information m ₁ , m ₂ , m ₃ in the vertical section with respect to the human body position information L ₁ , L ₂ , L ₃ ,. Is set to an approximate number of stitches so as to obtain a calculation result obtained by setting the Young's modulus E on the wale side as a constant value, and only the number of stitches is changed.

As for the base 10 of the elastic cylindrical bandage of the present embodiment, there are some which do not require adjustment of the length to be worn on the human body, such as a bandage, a supporter, and a sleeve. In such a case, the elastic cylindrical bandage of the above-described embodiment is spinning with human body position information L ₁ , L ₂ , L ₃ ,... Specified as the length direction of a part of the human body to be worn. the human body position information _L 1 stitch row of yarn wale side woven into a _circular, L _{2, L} 3, the body length of the outer periphery length in the vertical cross section against ... information _{m 1, m 2, m 3} , ·· An elastic cylindrical bandage that is worn in the length direction of a part of the human body knitted by using the human body position information L ₁ , L ₂ , L ₃ ,. The perimeter of the vertical section with respect to the human body perimeter information m ₁ , m ₂ , m ₃ ,... Is set to an approximate number of stitches so as to obtain a calculation result of calculating the waled stitch density and Young's modulus E. Is.

The base 10 of the elastic cylindrical bandage according to the present embodiment includes length-direction human body position information L ₁ , L ₂ , L ₃ ,... A part of the human body formed by weaving the perimeter of the vertical section with respect to the human body position information L ₁ , L ₂ , L ₃ ,... In the row as human body perimeter information m ₁ , m ₂ , m ₃ ,. It is an elastic cylindrical bandage to be worn in the length direction, and the human body circumference information m ₁ , m ₂ , m ₃ ,... Approximates the calculation result of calculating the waled stitch density and Young's modulus E The number of stitches to be set was set.
Therefore, the elastic cylindrical bandage according to the embodiment of the present invention can always be used because the elongation of the perimeter of the body of the knitted yarn row in which the spun yarn is knitted in an annular shape can be made constant according to the Young's modulus E and the number of stitches. A person can receive a uniform compression force from the entire elastic cylindrical bandage.

In addition, since the stitch density of the elastic cylindrical bandage of the present embodiment is made constant and the number of annular stitches is variable, the physical properties of the fabric are measured and the number of stitches that approximate the Young's modulus E is set. The elastic cylindrical bandage that can make the pressure distribution uniform and is worn in the length direction of a part of the human body can change the cross section of the human body even when the cross sectional shape of the human body with respect to the length is different, such as legs and arms. Correspondingly, by changing the stitches, it is possible to uniformly press the entire wearing part and to apply a custom-made pressing force in accordance with an individual case. Of course, it is also easy to create a standard that is a standard product from the user's data and the national average figure.
And since the elastic cylindrical bandage need only be worn against the elasticity in the length direction of a part of the human body, if an arbitrary pressure is applied to the length direction of a part of the human body without being an expert, If pressure is applied in the right-angle direction as needed, it is free to attach and detach, is easy to handle and carry, and has a single base that applies compression force. Is good. And since the elastic cylindrical bandage of this invention is knitted by the cylinder shape, winding cannot be unwound by a user's exercise | movement or the position to which it has mounted | worn does not move.

In this way, since the stitch density can be made constant, if the physical properties of the fabric are measured and the Young's modulus E is determined by determining the increase / decrease in the number of stitches, the pressure distribution can be stabilized at a desired value. In addition, the number of stitches on the wale side is determined by a non-sewn knit flat knitting machine, and the shape of the entire length is determined, so the end of a single spun yarn becomes one end, making it easy to manage the whole .
Furthermore, since the elastic cylindrical bandage of the embodiment of the present invention is single and the stitch density can be arbitrarily set by setting the number of stitches, the countermeasure for ventilation is perfect.
Therefore, the wearing feeling and the feeling of use are good, there is no sense of incongruity due to a well-balanced pressing force at the time of use, the wearing state is not released by the user's movement, and the movement of the position does not occur, Even if it is not an expert, it can be attached and detached without difficulty by applying a specific pressure, and air permeability can be secured.

In addition, the elastic cylindrical bandage of the above-described embodiment includes the human body position information L ₁ , L ₂ , L ₃ ,... In the length direction of a part of the human body to be worn and the human body position information L ₁ , It is mounted in the length direction of a part of the human body knitted using the human body perimeter information m ₁ , m ₂ , m ₃ ,... Of the perimeter in the vertical section with respect to L ₂ , L ₃ ,. Human body circumference information m ₁ , m ₂ , m ₃ ,... Elastic cylinder bandage, which is the circumference length of the vertical section with respect to human body position information L ₁ , L ₂ , L ₃ ,. .., a base 10 in which the number of stitches approximated so as to obtain a calculation result of calculating the Wale-side Young's modulus E with a constant density of the stitches on the wale side, and the number of stitches on the side closer to the heart from the base 10 Auxiliary fixing part 20 in which a knitted fabric with less elasticity is formed in an annular shape and an auxiliary of base 10 And a cutting portion 30 that can be cut with fraying stoppers arranged in a plurality of rings on the opposite side of the fixed portion 20, and the base portion 10, the auxiliary fixing portion 20, and the cutting portion 30 are knitted by one spun yarn, It can be understood that the spun yarn is folded back on the auxiliary fixing portion side 20 and the start end and the end end of the spun yarn are located on the cutting portion 30 side.

The elastic cylindrical bandage of the above-described embodiment is the above-described one-line stitch row in which spun yarns are knitted in an annular shape and the human body position information L ₁ , L ₂ , L ₃ ,. The length direction of a part of the human body formed by weaving the perimeter of the vertical section with respect to the human body position information L ₁ , L ₂ , L ₃ ,... As human body perimeter information m ₁ , m ₂ , m ₃ ,. Is the elastic cylindrical bandage attached to the body, and the perimeter information m ₁ , m ₂ , m ₃ ,... Represents the number of stitches approximating the calculation result of calculating the Weil's Young's modulus E. Formed on the opposite side of the set base 10, the auxiliary fixing portion 20 in which the number of stitches is increased from the base 10 toward the direction of the heart to form a ring with less elasticity, and the auxiliary fixing portion 20 of the base 10. A plurality of fraying stoppers arranged in a ring and provided with a cutting section 30 that can be cut freely; Part 30 is organized by a single spun yarn, in which yarn is turned back at the auxiliary fixing unit 20 side, the end of the beginning and end of the spun yarn is positioned in the cutting portion 30 side.

Therefore, the elastic cylindrical bandage of the present embodiment can always keep the elongation of the circumference of the human body of the knitted row on the wale side in which the spun yarn is knitted in an annular shape according to the stitch density, Young's modulus and number of stitches. The user can receive a uniform compression force from the cylindrical bandage.
Further, since the stitch density of the elastic cylindrical bandage of the present embodiment is made constant and the number of annular stitches is variable, the physical properties of the fabric are measured, and the setting is made by setting the stitch density, Young's modulus, and number of stitches. The elastic cylindrical bandage that can make the pressure distribution uniform and is worn in the length direction of a part of the human body can change the cross section of the human body even when the cross sectional shape of the human body with respect to the length is different, such as legs and arms. Correspondingly, the stitches are changed, and the entire body is uniformly compressed, and it is possible to apply a custom-made compression force according to an individual case. Of course, it is also easy to create a standard that is a standard product from the user's data and the national average figure.

And since the elastic cylindrical bandage of the present embodiment may be attached in the length direction of a part of the human body, even if it is not a skilled person, any pressure can be applied in the length direction of a part of the human body. It is easy to attach and detach, is easy to handle and carry, and has a single base for applying a pressing force. And since the elastic cylindrical bandage of this invention is knitted by the cylinder shape, winding cannot be unwound by a user's exercise | movement or the position to which it has mounted | worn does not move.
In this way, since the stitch density can be made constant, if the physical properties of the fabric are measured, and the Young's modulus E is determined by determining the increase / decrease in the number of stitches, the pressure distribution receiving the compression force can be stabilized to a desired value. Can do. In addition, since the number of annular stitches is determined by a non-sewn knit flat knitting machine and the shape of the entire length is determined, the end of a single spun yarn becomes one end, so that the entire management becomes easy.
Furthermore, since the elastic cylindrical bandage of the present invention is single, and the stitch density can be arbitrarily set by setting the number of stitches, the countermeasure for ventilation is perfect.
In addition, the cutting portion 30 of the present embodiment is provided with a plurality of fraying stoppers formed on the opposite side of the auxiliary fixing portion 20 of the base portion 10 so as to be cut freely. When a standard is created on the basis of the size, the cutting unit 30 can change the size according to the user's body, and can be selected based on the compression force that is an important factor for the user. Or, it is only necessary to cut according to the length of the arm, so that it is not necessary for the user to prepare special knowledge. Further, although the elastic cylindrical bandage of the present embodiment is formed by one spun yarn, it is cut at the end side of the spun yarn, so that the mechanical strength is reduced by partial cutting. There is nothing to do.

Further, the auxiliary fixing portion 20 is formed by specifying the number of annular stitches according to the human body perimeter information with respect to the length direction of a part of the human body at the part to be worn in the length direction of a part of the human body. The knitted fabric with less elasticity is formed in an annular shape by increasing the number of stitches from the base to the direction side close to the heart. In particular, the auxiliary fixing part 20 has a lower elastic force than the base 10, so it is part of the human body. On the other hand, the elastic force sufficient to maintain the position is maintained without biting in, and the elastic cylindrical bandage does not move without permission.
Therefore, the wearing feeling and the feeling of use are good, there is no sense of incongruity due to a well-balanced pressing force at the time of use, the wearing state is not released by the user's movement, and the movement of the position does not occur, Even if it is not an expert, it can be attached and detached without difficulty by applying a specific pressure, and air permeability can be secured.

Therefore, the elastic cylindrical bandage according to the present embodiment can make the elongation of the circumference of the human body of the stitch row on the wale side in which the spun yarn is knitted in an annular shape constant by calculating the number of stitches based on the stitch density and Young's modulus E. The user can always receive a uniform compression force from the elastic cylindrical bandage.

In addition, since the stitch density of the elastic cylindrical bandage according to the present embodiment is made constant and the number of annular stitches is variable, the physical properties of the fabric are measured, and the Young's modulus E and the number of stitches are set to determine the distribution of contact pressure. The elastic cylindrical bandage that is worn in the length direction of a part of the human body can respond to changes in the cross section of the human body even when the cross sectional shape of the human body with respect to the length is different, such as legs and arms. The stitches are changed, and the whole is uniformly compressed, and it is possible to apply a custom-made compression force according to an individual case. Of course, it is also easy to create a standard that is a standard product from the user's data and the national average figure.
And since it is only necessary to attach the elastic cylindrical bandage in the length direction of a part of the human body, even if it is not an expert, it is sufficient to apply arbitrary pressure to the length direction of a part of the human body, and it can be freely attached and detached. It is excellent in handling and carrying convenience, and since the base portion for applying a pressing force is formed in a single layer, the feeling of wearing and feeling of use are good. And since the elastic cylindrical bandage of this Embodiment is knitted by the cylinder shape, winding cannot be unwound by a user's exercise | movement or the position which has mounted | worn does not move.
In this way, since the stitch density can be made constant, if the physical properties of the fabric are measured and the Young's modulus E is determined by determining the increase / decrease in the number of stitches, the pressure distribution can be stabilized at a desired value. In addition, since the number of annular stitches is determined by a non-sewn knit flat knitting machine and the shape of the entire length is determined, the end of a single spun yarn becomes one end, so that the entire management becomes easy.

Furthermore, since the elastic cylindrical bandage of this embodiment is single and the stitch density can be arbitrarily set by setting the number of stitches, the countermeasure for ventilation is perfect.
In addition, the cutting part 30 is provided with a plurality of fraying stoppers formed on the opposite side of the auxiliary fixing part 20 of the base part 10 in a ring shape so that it can be cut. For example, a standard is created based on the compression force. In this case, the size can be changed by the cutting unit 30, and it is selected based on the compression force, which is an important factor for the user, and cut according to the length of the leg or arm. As a result, it is not necessary for the user to prepare special knowledge. Further, although the elastic cylindrical bandage of the present embodiment is formed by one spun yarn, it is cut at the end side of the spun yarn, so that the mechanical strength is reduced by partial cutting. There is nothing to do.
In addition, the auxiliary fixing unit 20 has the human body perimeter information m ₁ , m ₂ , m ₃ ,... Of the perimeter of the part to be worn in the length direction of a part of the human body with respect to the length direction of the part of the human body. Depending on the shape, the number of stitches is increased from the base 10 formed by specifying the number of annular stitches to the side closer to the heart to form a knitted fabric with less elasticity, and in particular, the auxiliary fixing portion 20 Since the elastic force is weaker than that of the base, the elastic cylindrical bandage of the present embodiment can move without permission while maintaining an elastic force that maintains its position without biting into a part of the human body. Absent.

In the elastic cylindrical bandage of the present embodiment, it is formed by one spun yarn, but is cut at the turn-back side of the spun yarn, so that it is halved by partial cutting. The spun yarn will break. Although the mechanical strength is not immediately reduced by cutting the spun yarn, the predetermined durability can be maintained by a method of preventing fraying of the cut spun yarn, tying, or bonding with a synthetic adhesive.
Therefore, the wearing feeling and the feeling of use are good, there is no sense of incongruity due to a well-balanced pressing force at the time of use, the wearing state is not released by the user's movement, and the movement of the position does not occur, Even if it is not an expert, it can be attached and detached without difficulty by applying a specific pressure, and air permeability can be secured.

The fraying prevention of the elastic cylindrical bandage of the present embodiment is made by applying a synthetic resin adhesive to the spun yarn knitting the base 10, the auxiliary fixing part 20, and the cutting part 30 and knitting the whole. When the spun yarn is continuously fed, an adhesive is attached everywhere, so that the fraying can be prevented from spreading even if it is cut. In particular, by using a colored adhesive, it is possible to clearly indicate the cutting location.
Further, as fraying prevention, the cut portion 30 may be knitted and a synthetic resin adhesive may be applied thereto. Since this type of fray stopper is one in which a synthetic resin adhesive is printed on the spun yarn knitting the base 10, the auxiliary fixing portion 20, and the cutting portion 30, and can be colored and printed, Printing with a predetermined width is also possible. By this printing, the adhesive joins the fibers and functions as a fray stop. In particular, by using a colored adhesive, it is possible to clearly indicate the cutting location.

The Young's modulus E on the wale side of the stitch row in which the spun yarn of the present embodiment is annularly knitted is compared with the Young's modulus E ₀ on the course side between the stitch rows in which the spun yarn is knitted in an annular shape. _It is set to ₀ .
Therefore, when an external force is applied to or attached to the elastic cylindrical bandage, since there is little elastic deformation in the direction of mounting on the human body, any movement is possible with a pressing force in the direction of mounting on the human body. Become.

By the way, in the said embodiment, the base 10 is the human body circumference information on the wale side of the circumference of the vertical section with respect to the human body position information (L ₁ , L ₂ , L ₃ ,...) In the length direction of the human body ( m ₁ , m ₂ , m ₃ ,...)) is an example in which the stitch density and Young's modulus are fixed and set to approximate numbers of stitches. The human body circumference information (m ₁ , m ₂ , m ₃ ,...) On the wale side of the vertical section with respect to the human body position information (L ₁ , L ₂ , L ₃ ,. The stitch density and Young's modulus can be made constant and set to an approximate number of stitches. Similarly, the auxiliary fixing unit 20 or the cutting unit 30 also has a human body perimeter information on the wale side of the vertical section with respect to the human body position information (L ₁ , L ₂ , L ₃ ,...) In the length direction of the human body ( m ₁ , m ₂ , m ₃ ,...) can be set to an approximate number of stitches with constant stitch density and Young's modulus.

According to the embodiment of the present invention, for example, the problems of the conventional elastic stockings are solved, the problem that the elderly's grip strength is weak and cannot be worn well, and the skin is allergic to nylon because of poor air permeability. The problem of easy reaction was also eliminated. And when wrinkles were formed on the elastic cylindrical bandage, it was freed from the phenomenon that the pressure was concentrated. Moreover, the problem that conventional products such as elastic stockings are foreigner-specific and unsuitable for the Japanese body shape can be eliminated by adopting domestic standards. Of course, it can be an original product tailored to each person's body shape.
In particular, in the conventional elastic cylindrical bandage, since the inner diameter of the cylinder is constant, several sizes corresponding to the parts of the human body are connected to each part, and the pressure is not stable because it becomes a joint. Although there were problems, the present invention solved such problems. The problem of easy eczema due to poor air permeability, poor durability, and poor appearance has also been resolved. In particular, although one unit is inexpensive, there are cases where several types are required depending on the affected limb, and as a result, the problem of high cost for the patient has been solved.

That is, since the elastic cylindrical bandage of the present embodiment is single, it has air permeability, and it is possible to achieve both reflux and vaporization acceleration. Moreover, since it can be manufactured from a cotton material, it is possible to manufacture a complicated elastic tubular bandage in the shape of a stocking or pantyhose that is suitable for the Japanese size. Moreover, it is possible to use a thick cotton fabric that does not easily become wrinkles, and a compression force of 20 mmHG can be obtained with a stepping pressure specification. Nevertheless, insertion and removal are easy. Moreover, it has a feature that it does not lose its shape even after repeated washing.
Furthermore, when used as a medical device as a supporter for lymphedema treatment or varicose veins, it is worn from the ankle side as the lower position of the calf, the upper position of the calf, the shin, the lower position of the knee, and the upper position of the knee No external force is applied only to specific parts during use.

The elastic clothing used in the present specification is a general term for elastic stockings, elastic sleeves, and elastic bandages used to treat lymphedema of the extremities.
In general, elderly people often have weak grip and cannot wear elastic stockings well. It can be widely used for the treatment of
Lymphedema refers to lymph nodes and lymphatic vessels that have been compressed, constricted, or obstructed for some reason, causing lymphatic stagnation and excessive accumulation of water (including protein and lymphocytes) in tissues and cells. State. Currently, Japanese clothing industry's voluntary standards that require compression force of 30mmHG or higher are treated as elastic clothing.

The elastic cylindrical bandage is, for example, an elastic bandage used to reduce edema in patients with end-stage cancer, and several types may be necessary depending on the site of edema in the patient. Medical expenses are applied according to the doctor's wearing instructions. However, the elastic cylindrical bandage defined in the present invention is a bandage, supporter, sleeve, stocking, underwear, etc. wearing device made of a stretchable fabric that is used in a compression method that compresses a part of the human body. Can be used as a seamless molded elastic bandage, for example, it can be treated as a medical device that can also be used especially as a supporter for the treatment of lymphedema or varicose veins, or as an arm, leg, head, foot In some cases, it is used as an elastic cylindrical bandage that applies compression force from the outside of the hand, etc., and can be used to improve and prevent edema of the limb trunk by applying pressure to the necessary part of the limb trunk. It includes things.

In the above embodiment, only the base 10 has been described with an example in which the stitch density and Young's modulus are constant and set to an approximate number of stitches, but a wearing device for compression such as a bandage, supporter, sleeve, stocking, underwear, As a supporter for lymphedema treatment or a supporter for varicose veins, the whole part including the added part can be used as the base part, or the attached part can be removed.
