Description

【0001】
【発明の属する技術分野】
本発明はバンデ−ジに関し、特に外傷の発生予防、再発予防、患部の固定や圧迫等の応急処置、治療などに用いられる医療用、スポ−ツ用のバンデ−ジに関する。
【0002】
【従来の技術】
従来から、人体、特に足関節や手関節等の関節部の捻挫や大腿部等の肉離れなどの外傷の予防、これらの外傷を受傷したときの応急処置、受傷後から完全回復までのリハビリテ−ションの補助、外傷等の再発予防などの医療用の目的に対応するために、主としてバンデ−ジ、テ−ピングテ−プ、サポ−タ−などが使用されている。
粘着剤を使用しているテ−ピングテ−プやサポ−タ−にはそれぞれに利点があるけれども、バンデ−ジには、患部に追従し易く、自分で固定力を調整しながら巻付けることができ、体の動きに対して無理な力がかからず、安定した固定性が得られ、反復使用ができるという経済性もあって、有益なものの一つである。
【0003】
また、サッカ−、ラグビ−、アメリカンフットボ−ルなどの競技者間のコンタクトが多いスポ−ツでは、捻挫や肉離れなどが頻繁に起こるために、受傷した場合は勿論のこと、外傷の予防や再発防止のために、関節などの固定が有効であるといわれている。
特にサッカ−では足先の微妙な動きでボ−ルをコントロ−ルし、細かなカットを切るためには、足関節を固定する場合にも適度の固定性とフレキシビリティ−が必要であり、靴へのフィット性も必要とされる。
こうしたことから、バンデ−ジは、その適度の固定性、動きに対するフレキシビリティ−を有しており、特別の技術を必要とせずに巻付けでき、また洗って繰り返し使用できる経済性から今迄も広く使用されてきた。
【0004】
しかしながら、従来のバンデ−ジは多くが荷重時の下記する伸長率(JIS L1096に準ずる・以下同じ) が70〜100 %という高伸縮性のものである。このバンデ−ジは伸びが大きくて固定力が弱くなる傾向があり、また一旦固定しても徐々に元の状態に回復しようとして緩んだりするし、固定力を上げるために巻く回数を増やすと嵩高となって違和感が生じることもある。また、平織りとされた織り密度が比較的小さい物が多く、繰返し使用による劣化や伸長率が変わるなどの物性変化が起り易いものであった。
【0005】
また、平織りの織布で伸長率を30%程度としたものも一部知られているが、幅方向には殆んど伸長しないために、比較的フラットな患部に巻いたときには固定性が得られるが、足関節などの曲面形状部分には充分に追従することができずに巻きにくく十分な固定性が得にくいこともあった。
【0006】
【発明が解決しようとする課題】
本発明は、患部に対して充分な固定性を得ると共に、曲面形状部分に対しても追従性を向上させてずれ易さを防止し、使用中は患部を違和感なく確実に固定維持することができ、更に繰り返し使用することができるようなバンデ−ジを得ようとするものである。
【0007】
【課題を解決するための手段】
本発明は、長さ方向の伸長率を比較的低くすると共に幅方向にも若干の伸長率を与えるようにしてバンデ−ジを形成する。長さ方向の伸長率は約10〜40%程度で、幅方向の伸長率は約4〜15%程度にするとよい。
こうした長さ方向及び幅方向の伸長率は、織物を綾織にすることによって得ることができる。また、長さ方向の経糸と幅方向の緯糸の2.54cm(1インチ)当りの本数を制御し、糸に撚糸を使用することによって更に好ましいバンデ−ジを得ることができる。
【0008】
【発明の実施の形態】
本発明のバンデ−ジは、織物によって形成すると好ましく、編物では全体的に伸縮性が高く嵩高であるために、上記の如き低伸長率を得ることが難かしいことが多いし、巻き重ねによってボリュームが大きくなる。
織物は、各種の天然繊維、化学繊維の単体の糸、これらの繊維の適宜の混紡糸などによって形成し、好ましくは木綿、レ−ヨン、ナイロン、ポリエステル、アクリルなどの単体糸やこれらの混紡糸にするとよい。更に、吸湿性が高くて肌触りの良好な木綿、適当な腰があって安定性に優れており他の繊維との馴染みが良いポリエステル、軽くて柔らかく染色し易いアクリルなどを単体で、またはこれらを適当に組合せた混紡糸は良好に使用することができる。
【0009】
上記繊維を使用した織物は、平織よりも綾織とすることが好ましい。綾織は、1/2綾、2/2綾、1/3綾、2/3綾、3/3綾、1/4綾、2/4綾、3/4綾、4/4綾等とすれば、製造工程が簡単であって組織の安定性が良く、適当な強度が得られて好ましいことが多い。
【0010】
糸の太さは、10番手〜80番手程度のものがよく、好ましくは20番手〜40番手がよい。10番手未満のものを使用すると糸が太すぎてバンデ−ジがごわごわとし、組織も安定化せず縮れやゆがみが生じて、全体に硬い感じのものとなって好ましくない。また、80番手より上のものでは、糸が細いために表面にクレ−プが出来やすくなり、織物全体としての耐久性も低いものとなる。
【0011】
上記糸は強度が高く、織物にしたときに引締った感じのする双糸等の撚糸が好ましい。双糸を用いる場合、単糸をZ撚りし、その単糸2本をS撚りして双糸とするとよい。経糸では撚り回数を約1000〜2500回/m程度とするとよく、好ましくは約1200〜2000回/m程度とする。この場合、1000回未満だと伸縮性が十分でないし、糸の強度も低く、織物のへたりが生じ易くなる。また、2500回を越えると巻縮が発生し易く、糸も硬くなって肌触りが悪くなる。緯糸は、撚り回数を約 200〜1000回/m程度のものとすると、十分な糸強度と仕上り具合の良いものが得られる。
【0012】
糸の密度は、長さ方向の経糸、幅方向の緯糸の一方を他方の1〜1.7倍程度にするとよく、また、2.54cm当り25本以上の打込み本数として、余り疎な状態でない方が好ましい。例えば、20〜30番手の糸であれば2.54cm当り約30〜55本、40番手であれば40〜80本程度を目安とすればよい。
また、織物の目付量は約125〜460g/m程度にすると好ましいことが多い。
こうして、長さ方向の伸長率が10〜40%、幅方向の伸長率が4〜15%のバンデ−ジを得ることができる。
【0013】
【実施例】
経糸には綿糸100%の単糸を1700回/mでZ撚りし、その双糸を1900回/mでS撚りした40番手の双糸を使用した。緯糸には同じく綿糸100%の単糸を400回/mでZ撚りし、その双糸を400回/mでS撚りした20番手の双糸を使用した。
上記経糸を2.54cm当り54本、緯糸を41本の打込み本数とし、2/2の綾織としたもので、バンデ−ジを形成した。

上記経糸を2.54cm当り45本、緯糸を19本の打込み本数とし、平織りしたものでバンデ−ジを形成した。
【0015】
〔比較例2〕
経糸に綿糸100%の単糸を1700回/mでZ撚りし、その双糸を1900回/mでS撚りした30番手の双糸を使用した。緯糸には同じく綿糸100%の単糸を400回/mでZ撚りし、その双糸を400回/mでS撚りした20番手の双糸を使用した。
上記経糸を2.54cm当り45本、緯糸を41本の打込み本数とし、平織りしたものでバンデ−ジを形成した。

(物理特性の考察)
実施例のものでは伸長率が長さ方向に20〜35%であり、幅方向にも 5〜13%の伸長が見られ、厚みも薄くなって残留ひずみ率も低下している。
これに対し、比較例1では、長さ方向の伸長率が大きく、厚みも厚くなっており、残留ひずみ率が大きく、伸長率の低下も大きい。また、比較例2では、長さ方向の伸長率は実施例と同等であるが、幅方向の伸長率が小さく、厚みも厚くなっている。
【0019】
〔試用試験1〕
試用試験1として、現役大学男子サッカ−選手12名の12足を対象に、それぞれ上記実施例、比較例1(高伸長性)、比較例2(低伸長性)の3種類のバンデ−ジを用いて足関節を固定し、その固定力を比較した。比較内容は、足関節固定器テロスSEを用いたストレスX線撮影像より計測した固定前、固定直後、30分運動後の距骨傾斜角とした。
上記運動はサッカ−の競技特性を考慮してランニング、アジリティ−ドリル、ミニゲ−ムを組合せた内容とし、運動時平均心拍数が 150〜160 拍/min になるよう強度設定した。また固定方法は、フィギュアエイトとヒ−ルロックの繰り返し固定とした。
距骨傾斜角の変化率は次式によって求めた。
距骨傾斜角の変化率={(運動後の距骨傾斜角−固定直後の距骨傾斜角)/固定直後の距骨傾斜角}×100
(運動後にずれた距骨傾斜角が最初の固定状態に対しどれだけの割合があるか示す値。少ないほうが固定性が良いことを示す。)
計測値及び変化率を表2に示す。

【0021】
(結果の考察)
距骨傾斜角の測定の結果、実施例は固定直後、運動後の距骨傾斜角がともに比較例1、2の距骨傾斜角より小さく、実施例は固定力が高いことが判る。特に運動後の距骨傾斜角において、実施例は比較例1、2に比べて顕著に小さく、実施例は運動してもバンデ−ジが緩みにくく(距骨傾斜角の変化率が低い)、固定力を長時間維持していることが認められる。
【0022】
〔試用試験2〕
試用試験2として上記試用試験1と同内容の実験により、選手の主観的評価を比較した。対象の12名に対して3種類のバンデ−ジによる固定と運動を実施した後に、固定性、固定性の持続性、ずれにくさ、運動への悪影響という観点でどの固定法が最も良かったかを調査した。調査は、上記実施例、比較例1、比較例2の3種類のバンデ−ジの中で最も優れていると思うものを選んでもらった。

【発明の効果】
本発明によれば、上記したとおり、長さ方向には比較的低伸長性とし、かつ幅方向にもある程度の伸長性を持たせることによって、固定力を向上させると共に、患部への追従性を上げ、ずれを減少させて使用中の固定性の維持を図ることができ、外傷の予防、治療等に有効に使用することができる。[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bandage, and more particularly to a bandage for medical use and sports used for prevention of trauma occurrence, prevention of recurrence, emergency treatment such as fixation and compression of an affected part, and treatment.
[0002]
[Prior art]
BACKGROUND ART Conventionally, prevention of injuries such as sprains of human body, especially joints such as ankle joints and wrist joints and detachment of muscles in thighs, etc., emergency treatment when these injuries are injured, and rehabilitation from injuries to complete recovery Bandages, taping tapes, supporters, and the like are mainly used for medical purposes such as assisting in medical treatment and preventing recurrence of trauma.
Taping tapes and supporters that use adhesives have their own advantages, but the bandage can easily follow the affected area and can be wound by adjusting the fixing force by yourself. It is one of the useful ones, because it does not exert excessive force on the movement of the body, provides stable fixation, and has the economical efficiency of repeated use.
[0003]
Also, sports such as soccer, rugby, and American football have many contacts between athletes, and sprains and loosening occur frequently. It is said that fixation of joints and the like is effective for prevention.
Especially in the sucker, the ball is controlled by the delicate movement of the tip of the foot, and in order to cut the fine cut, even when fixing the ankle joint, appropriate fixation and flexibility are necessary, Fitting to shoes is also required.
For these reasons, the bandage has an appropriate degree of fixation and flexibility for movement, can be wound without requiring any special technique, and has been economically washed and used repeatedly. Widely used.
[0004]
However, most of conventional bandages have a high elasticity of 70 to 100% in the following elongation rate under load (according to JIS L1096, the same applies hereinafter). This bandage tends to have a large elongation and a weak fixing force. Also, once the bandage is fixed, it loosens in order to gradually recover to its original state. It may cause discomfort. In addition, many plain weaves having a relatively low weave density tended to undergo physical property changes such as deterioration and elongation due to repeated use.
[0005]
Some plain woven fabrics with an elongation ratio of about 30% are also known, but since they hardly elongate in the width direction, they have good fixation when wrapped around a relatively flat affected area. However, in some cases, it is difficult to follow a curved surface portion such as an ankle joint, so that it is difficult to wind up and obtain sufficient fixation.
[0006]
[Problems to be solved by the invention]
The present invention obtains sufficient fixability to the affected part, improves the followability also to the curved surface part, prevents easiness of displacement, and securely fixes and maintains the affected part without discomfort during use. An object of the present invention is to provide a bandage that can be used and can be used repeatedly.
[0007]
[Means for Solving the Problems]
According to the present invention, the bandage is formed so as to have a relatively low elongation in the length direction and a slight elongation in the width direction. The elongation rate in the length direction is preferably about 10 to 40%, and the elongation rate in the width direction is preferably about 4 to 15%.
Such elongation rates in the length and width directions can be obtained by making the woven fabric a twill weave. A more preferable bandage can be obtained by controlling the number of warps in the length direction and the number of wefts in the width direction per 2.54 cm (1 inch) and using a twisted yarn as the yarn.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
The bandage of the present invention is preferably formed of a woven fabric. Since the knitted fabric has high elasticity and bulkiness as a whole, it is often difficult to obtain the low elongation as described above. Becomes larger.
The woven fabric is formed by single yarns of various natural fibers and chemical fibers, and appropriate blended yarns of these fibers, preferably single yarns of cotton, rayon, nylon, polyester, acrylic and the like, and blended yarns thereof. It is good to In addition, cotton with good moisture absorption and good touch, polyester with a suitable waist, excellent stability and familiarity with other fibers, acrylic that is light, soft and easy to dye, etc. Properly blended blended yarns can be used successfully.
[0009]
The woven fabric using the above fibers is preferably a twill rather than a plain woven. The twill weave is 1/2, 2/2, 1/3, 2/3, 3/3, 1/4, 2/4, 3/4, 4/4, etc. In many cases, the manufacturing process is simple, the stability of the tissue is good, and appropriate strength is obtained.
[0010]
The thickness of the yarn is preferably about 10th to 80th, and more preferably 20th to 40th. If the yarn is less than 10th, the yarn is too thick and the bandage becomes stiff, and the structure is not stabilized, and shrinkage or distortion occurs. On the other hand, if the yarn is higher than 80, crepe is easily formed on the surface because the yarn is thin, and the durability of the whole woven fabric is low.
[0011]
The yarn is preferably a twisted yarn, such as a twin yarn, which has high strength and gives a tight feeling when woven. When a twin yarn is used, a single yarn is preferably Z-twisted, and two of the single yarns are S-twisted to form a twin yarn. In the case of a warp, the number of twists is preferably about 1000 to 2500 times / m, and more preferably about 1200 to 2000 times / m. In this case, if it is less than 1,000 times, the elasticity is not sufficient, the strength of the yarn is low, and the woven fabric is apt to set. On the other hand, when the number of times exceeds 2,500, crimping is liable to occur, the yarn becomes hard and the feel becomes poor. When the number of twists of the weft is approximately 200 to 1,000 times / m, a yarn having sufficient yarn strength and good finish can be obtained.
[0012]
The density of the yarn is preferably about 1 to 1.7 times that of one of the warp in the length direction and the weft in the width direction, and is not very sparse as the number of drivings is 25 or more per 2.54 cm. Is more preferred. For example, about 30 to 55 threads per 2.54 cm for a 20th to 30th thread, and about 40 to 80 threads for a 40th thread.
Further, it is often preferable that the basis weight of the woven fabric be about 125 to 460 g / m 2 .
Thus, a bandage having an elongation ratio in the length direction of 10 to 40% and an elongation ratio in the width direction of 4 to 15% can be obtained.
[0013]
【Example】
As the warp, a 40% double yarn in which a 100% cotton single yarn was Z-twisted at 1,700 times / m and the twin yarn was S-twisted at 1,900 times / m, was used. As the weft, a 20th-number twin yarn in which a 100% cotton single yarn was Z-twisted at 400 times / m and the twin yarn was S-twisted at 400 times / m.
A bandage was formed by using the above-mentioned warp yarns with a driving number of 54 per 2.54 cm and weft yarns of 41 and a 2/2 twill weave.
[0014]
[Comparative Example 1]
As the warp, a 100% cotton single yarn was Z-twisted at 1700 times / m and the twin yarn was S-twisted at 1900 times / m to use a 30th-number twin yarn. As the weft, a 20th-number twin yarn in which a 100% cotton single yarn was Z-twisted at 400 times / m and the twin yarn was S-twisted at 400 times / m.
A bandage was formed by plain weaving the above-mentioned warp yarns at 45 per 2.54 cm and weft yarns at 19 per unit.
[0015]
[Comparative Example 2]
As the warp, a 100% cotton single yarn was Z-twisted at 1700 times / m and the twin yarn was S-twisted at 1900 times / m to use a 30th-number twin yarn. As the weft, a 20th-number twin yarn in which a 100% cotton single yarn was Z-twisted at 400 times / m and the twin yarn was S-twisted at 400 times / m.
A bandage was formed by plain weaving the above-mentioned warp yarns at 45 per 2.54 cm and 41 weft yarns.
[0016]
The physical properties of the above Examples, Comparative Examples 1 and 2 were measured as follows.
○ Elongation rate: According to JIS L1096 (constant speed elongation method), grip the test piece at 20 cm (5 cm in the width direction), attach it to a tensile tester, and apply a load at a pulling speed of 100% of the grip interval per minute. Draw an elongation curve. The elongation ratio under a load of 14.71 N is determined from this curve and is represented by an average value of three times.
For the measurement in the length direction, a test piece having a length of 30 cm × width 5 cm and a length of 10 cm × width 5 cm was used in the width direction.
Elongation% = {(L1-L0) / L0} × 100
L0: gripping distance 20 cm (5 cm in the width direction), L1: length of gripping distance when a load of 14.71 N is applied (cm)
○ Thickness: In accordance with JIS L1096 (thickness), an initial load of 0.25 N / cm 2 (500 g load on a φ2.5 cm holder) was applied to five different portions of the sample using a thickness measuring device for 10 seconds. The thickness afterwards is measured and expressed as the average value.
○ Elongation recovery rate, residual strain rate: According to the constant load method of JIS L1096 (elongation recovery rate and residual strain rate), a test piece of 30 cm in length x 5 cm in width is marked at intervals of 20 cm, and a load of 14.71 N is applied. In addition, measure the length between labels one hour later. Then, the length between the labels 1 hour after debulking was measured, and the elongation recovery rate was determined by the following formula, and the average of three times was obtained. The higher the value, the better the recovery rate.
Elongation recovery rate (%) = {(L1-L1 ′) / (L1-L0)} × 100
Residual strain rate (%) = {(L1-L0) / L0} × 100
L0: length between the original signs 20 cm, L1: length between the signs after applying 1.5 kg of load for 1 hour (cm), L1 ′: when the initial load is applied 1 hour after de-weighting Length between signs (cm)
○ Decrease in elongation rate: Wear bandages on ankle joints of 12 persons for 3 hours and wash. This process is performed once, and the process is repeated 30 times under the same conditions, and the average value of the elongation ratio before and after use is compared.
Table 1 shows the measurement results.
[0017]
[Table 1]
Figure 0003603276
[0018]
(Consideration of physical properties)
In the example, the elongation rate is 20 to 35% in the length direction, and the elongation is 5 to 13% in the width direction. The thickness is reduced and the residual strain rate is reduced.
On the other hand, in Comparative Example 1, the elongation rate in the length direction is large and the thickness is large, the residual strain rate is large, and the decrease in the elongation rate is large. In Comparative Example 2, the elongation rate in the length direction is the same as that of the example, but the elongation rate in the width direction is small and the thickness is large.
[0019]
[Trial test 1]
As a trial test 1, three types of bandages of the above-described Example, Comparative Example 1 (high extensibility), and Comparative Example 2 (low extensibility) were respectively applied to 12 feet of 12 active college male suckers. Was used to fix the ankle joint, and the fixing force was compared. The content of comparison was the talus inclination angle before fixation, immediately after fixation, and after 30 minutes of exercise measured from stress X-ray images using the ankle fixation device Telos SE.
The exercise was performed by combining running, agility drill, and mini-game in consideration of the game characteristics of the sucker, and the intensity was set so that the average heart rate during exercise was 150 to 160 beats / min. The fixing method was to repeatedly fix figure eight and hill lock.
The change rate of the talus inclination angle was obtained by the following equation.
Rate of change of talus inclination angle = {(talar inclination angle after exercise-talus inclination angle immediately after fixation) / talus inclination angle immediately after fixation} x 100
(Value indicating how much the talus tilt angle shifted after exercise is relative to the initially fixed state. A smaller value indicates better fixation.)
Table 2 shows the measured values and the rate of change.
[0020]
[Table 2]
Figure 0003603276
[0021]
(Discussion of results)
As a result of the measurement of the talus inclination angle, it can be seen that the talus inclination angle of the example immediately after fixation and the talus inclination angle after exercise are both smaller than the talus inclination angles of Comparative Examples 1 and 2, and that the example has a high fixing force. In particular, the talus inclination angle after exercise is significantly smaller in the example than in Comparative Examples 1 and 2, and in the example, the bandage is less likely to loosen even when exercising (the rate of change in the talus inclination angle is low), and the fixing force is low. Is maintained for a long time.
[0022]
[Trial test 2]
As a trial test 2, the subjective evaluation of the players was compared by an experiment having the same contents as the trial test 1 described above. After performing fixation and exercise with three types of bandages on 12 subjects, it was determined which fixation method was the best in terms of fixation, persistence of fixation, difficulty in slipping, and adverse effects on exercise. investigated.
