Description

本発明は、繊維補強ポリカプロラクトンを軟化させて装着部位に沿わせて変形してなるポリカプロラクトン製装具、及び、その製造方法に関する。さらに詳しくは、装着者の装着部位に直に又は衣服等を介して間接にあてがって形をとることができる成形材料を用いた、成形後にも形状調節が容易な装具、及び、石膏型等の型取り工程が不要なプラスチック製装具の製造方法に関する。   TECHNICAL FIELD The present invention relates to a polycaprolactone orthosis formed by softening fiber-reinforced polycaprolactone and deforming it along an attachment site, and a method for manufacturing the same. In more detail, a molding material using a molding material that can be applied directly to the wearer's wearing site or indirectly through clothing, etc., and can be easily adjusted after molding, such as a plaster mold, etc. The present invention relates to a method for manufacturing a plastic orthosis that does not require a molding process.

プラスチック製装具は装着者の治療、更生、矯正、歩行、運動等の支援や補助等の目的で使用されており、ポリプロピレンやポリエチレン等の熱可塑性樹脂が広く使用されている。しかしながら、このようなプラスチックを材料とした場合、強度が不足するため、肉厚の材料を使用したり、材料を褶曲させてリブを設ける等の工夫が必要であった。そのため、装具が嵩高となり、例えば、一方の下肢に装具を装着すると両方の足に同じサイズの靴を履く事ができず、装着性が悪かったり、外観を損ねることがあった。   Plastic orthoses are used for the purpose of assisting and assisting wearer's treatment, rehabilitation, correction, walking, exercise, etc., and thermoplastic resins such as polypropylene and polyethylene are widely used. However, when such a plastic is used as a material, the strength is insufficient, and therefore, it is necessary to devise such as using a thick material or bending the material to provide a rib. For this reason, the brace becomes bulky. For example, if the brace is worn on one leg, it is impossible to wear shoes of the same size on both feet, and the wearability may be poor or the appearance may be impaired.

また、従来、熱可塑性樹脂を加熱可塑化して装具を成形するには少なくとも150℃程度、又はそれ以上の加熱が必要であった。従って、装具を装着者の装着部位に合わせるためには、装着部位の石膏型等を採取し、この型に沿わせて変形させることが必要であり、型の製造に伴う手間や時間が必要で、装具の完成に時間がかかった。また、肉厚材料を使用する場合は、変形作業が困難で、踵等に沿わせて変形するような深い加工の自由度が制約されたり、伸展による厚みが均一になりにくい等の加工の困難があった。   Further, conventionally, heating of at least about 150 ° C. or more has been required to form a brace by heat plasticizing a thermoplastic resin. Therefore, in order to match the brace to the wearing part of the wearer, it is necessary to collect a gypsum mold etc. of the wearing part and deform it along this mold, and labor and time involved in mold production are required. It took time to complete the brace. In addition, when using thick materials, it is difficult to perform deformation work, which limits the degree of freedom of deep processing that deforms along wrinkles, etc., and makes processing difficult, such as difficult to achieve uniform thickness due to extension. was there.

例えば、特許文献1には、炭素繊維とプラスチック樹脂との複合材料からなる膝装具の製造において、患者の脚の輪郭に応じた形状に成形するために、およそ200℃の加熱が必要であることが記載されている。一方、加熱をしないで支持対象の形状に個別成形される装具が特許文献2に記載されているが、湿気硬化性樹脂を使用しており、成形後の形状等の調節は困難である。
特開平9−313512号公報 特表2006−514863号公報
For example, in Patent Document 1, in manufacturing a knee brace made of a composite material of carbon fiber and plastic resin, heating at about 200 ° C. is required in order to form a shape corresponding to the contour of a patient's leg. Is described. On the other hand, a device that is individually molded into a shape to be supported without heating is described in Patent Document 2, but a moisture curable resin is used, and it is difficult to adjust the shape after molding.

本発明における成形材料(以下、とくに断らないかぎり、補強用成形材料を含む。)は、ポリカプロラクトンを有機又は無機の繊維に含浸させてなる。ポリカプロラクトンは、ε−カプロラクトンの重合体であり、融点は60℃である。ポリカプロラクトンは、ε−カプロラクトンを、重合開始剤(例えば、アルキレングリコール、芳香族ジオール、脂環式ジオール、ポリエチレングリコール等)、必要に応じて、触媒(例えば、テトラブチルチタネート、ジブチルスズオキシド、オクチル酸スズ、塩化第一スズ等)を使用しつつ、公知の方法で重合することにより製造できる。   The molding material in the present invention (hereinafter including a reinforcing molding material unless otherwise specified) is formed by impregnating organic or inorganic fibers with polycaprolactone. Polycaprolactone is a polymer of ε-caprolactone and has a melting point of 60 ° C. Polycaprolactone is obtained by converting ε-caprolactone into a polymerization initiator (eg, alkylene glycol, aromatic diol, alicyclic diol, polyethylene glycol, etc.), and optionally a catalyst (eg, tetrabutyl titanate, dibutyltin oxide, octylic acid). Tin, stannous chloride, etc.) can be used for polymerization by a known method.

本発明において、ポリカプロラクトンをワニスとして得ることが好ましく、ワニス中のポリカプロラクトンの数平均分子量は2万〜10万であることが好ましく、より好ましくは2.5万〜8万である。数平均分子量2万未満であると、樹脂自体に備わっていなければならない機械的強度や耐熱性が充分でないおそれがあり好ましくない。数平均分子量10万を超えると、たとえ溶剤で溶かしても粘性係数が大きいため有機又は無機の繊維に充分に含浸しなくなるおそれがあり好ましくない。   In the present invention, it is preferable to obtain polycaprolactone as a varnish, and the number average molecular weight of the polycaprolactone in the varnish is preferably 20,000 to 100,000, more preferably 25,000 to 80,000. If the number average molecular weight is less than 20,000, the mechanical strength and heat resistance which must be provided in the resin itself may not be sufficient, which is not preferable. If the number average molecular weight exceeds 100,000, the viscosity coefficient is large even if dissolved in a solvent, and therefore, the organic or inorganic fiber may not be sufficiently impregnated, which is not preferable.

ポリカプロラクトンワニスを得るための溶剤としては、例えば、酢酸エチル、酢酸プロピル、酢酸ブチル、テトラヒドロフラン、セロソルブアセテート、メチルセロソルブ、ブチルセロソルブ、メチルカルビトール、プロピレングリコールメチルエーテルアセテート等を挙げることができる。   Examples of the solvent for obtaining the polycaprolactone varnish include ethyl acetate, propyl acetate, butyl acetate, tetrahydrofuran, cellosolve acetate, methyl cellosolve, butyl cellosolve, methyl carbitol, propylene glycol methyl ether acetate and the like.

本発明において、ポリカプロラクトンワニスに有機過酸化物をポリカプロラクトン100重量部に対して、好ましくは0.1〜10重量部含有させ、ポリカプロラクトンが未架橋のワニスを繊維基材に含浸させプリプレグ材とし、その後、プリプレグ材の溶剤を揮発させる加熱・乾燥工程、あるいはプリプレグ成形材料を加熱加圧することにより、ポリカプロラクトンを架橋(例えば、微架橋)させることもできる。有機過酸化物を含有させなければ、補強成形材料を強固に自着させることができ、有機過酸化物を含有させれば、成形材料の強度を向上させることができる。   In the present invention, a polycaprolactone varnish contains an organic peroxide in an amount of preferably 0.1 to 10 parts by weight with respect to 100 parts by weight of polycaprolactone, and a fiber base material is impregnated with an uncrosslinked polycaprolactone varnish. Then, polycaprolactone can be crosslinked (for example, micro-crosslinked) by heating / drying step for volatilizing the solvent of the prepreg material, or by heating and pressurizing the prepreg molding material. If the organic peroxide is not contained, the reinforcing molding material can be firmly adhered, and if the organic peroxide is contained, the strength of the molding material can be improved.

有機過酸化物としては、例えば、オクタノイルパーオキサイド、ラウロイルパーオキサイド、ステアロイルパーオキサイド、アセチルパーオキサイド、ベンゾイルパーオキサイド、t−ブチルパーオキシマレイン酸、t−ブチルパーオキシイソブチレート、メチルエチルケトンパーオキサイド、ジクミルパーオキサイド、2,5−ジメチル−2,5−ビス(t−ブチルパーオキシ)ヘキシン−3等を挙げることができる。   Examples of the organic peroxide include octanoyl peroxide, lauroyl peroxide, stearoyl peroxide, acetyl peroxide, benzoyl peroxide, t-butyl peroxymaleic acid, t-butyl peroxyisobutyrate, and methyl ethyl ketone peroxide. , Dicumyl peroxide, 2,5-dimethyl-2,5-bis (t-butylperoxy) hexyne-3, and the like.

本発明に使用される成形材料は、例えば、ポリカプロラクトンワニスを繊維基材に含浸させた後、例えば、90〜220℃で加熱乾燥し溶剤を揮発させて得ることができる。なお、ポリカプロラクトンワニスに有機過酸化物を含む場合は、有機過酸化物の活性化温度以下で、例えば130℃以下の温度で加熱乾燥することが好ましい。この場合、130℃超過の温度で溶剤を揮発させると、ポリカプロラクトンの架橋が進行してしまい、成形材料同士を自着、すなわち、接着剤を使用することなく、軟化させた材料同士を接着させること、をさせにくくなる。   The molding material used in the present invention can be obtained, for example, by impregnating a fiber base with a polycaprolactone varnish and then drying by heating at 90 to 220 ° C. to evaporate the solvent. In the case where the polycaprolactone varnish contains an organic peroxide, the polycaprolactone varnish is preferably heated and dried at a temperature not higher than the activation temperature of the organic peroxide, for example, 130 ° C. or lower. In this case, if the solvent is volatilized at a temperature exceeding 130 ° C., the crosslinking of polycaprolactone proceeds, and the molding materials are self-attached, that is, the softened materials are bonded to each other without using an adhesive. It becomes difficult to do that.

本発明における成形材料中の繊維基材は長繊維基材である。かかる長繊維基材の形態としては、織物若しくは編物、又は長繊維のステッチ基材を挙げることができる。これらの長繊維基材を用いることにより、本発明における成形材料は適度の柔軟性、伸縮性、引張強度、通気性等の特性を備えることができる。そのため、長繊維基材の形態としては編物がより好ましい。   The fiber base material in the molding material in the present invention is a long fiber base material. Examples of the form of the long fiber base material include a woven fabric or a knitted fabric, or a long fiber stitch base material. By using these long fiber base materials, the molding material in the present invention can have characteristics such as appropriate flexibility, stretchability, tensile strength, and air permeability. Therefore, a knitted fabric is more preferable as the form of the long fiber base material.

本発明における成形材料中の繊維基材の繊維としては、ポリカプロラクトンを含浸させて複合材料とすることができるものであれば特に限定されず、例えば、ガラス繊維、ケナフ繊維、竹繊維、綿繊維、アラミド繊維、ポリ乳酸(PLA)繊維、ポリエステル繊維、又はビニロン繊維等の有機又は無機の繊維を挙げることができる。なお、本発明において、繊維はポリカプロラクトンとの密着性を向上させるために、表面処理されていてもよい。例えば、ガラス繊維であれば、シランカップリング剤で処理してもよい。   The fiber base fiber in the molding material in the present invention is not particularly limited as long as it can be impregnated with polycaprolactone to form a composite material. For example, glass fiber, kenaf fiber, bamboo fiber, cotton fiber And organic or inorganic fibers such as aramid fiber, polylactic acid (PLA) fiber, polyester fiber, or vinylon fiber. In the present invention, the fiber may be surface-treated in order to improve the adhesion with polycaprolactone. For example, if it is glass fiber, you may process with a silane coupling agent.

上記繊維基材は、単位面積当たりの質量が100〜500g/mであることが好ましく、200〜350g/mであることがより好ましい。さらに、繊維基材の総面積のうち繊維と繊維の間隙である穴の占める面積の比である開口率は、15〜60%であることが好ましく、20〜50%であることが更に好ましい。尚且つ繊維と繊維の間隙である穴の代表寸法は、0.5〜5.0mmであることが好ましく、1.0〜3.0mmが更に好ましい。本発明において開口率とは、4mm角の繊維基材試料20個について、画像処理機(日本アビオニクス社製TVイメージプロセッサEXCEL)を用いて、Image Command4198のソフトウエアにより実体顕微鏡(倍率67倍)で測定し、穴部の画素数比を求めた夫々の繊維基材試料についての値の平均値である。また、上記穴の代表寸法とは、開口率と同様の測定方法により、夫々の繊維基材試料の穴における繊維と繊維の間隙が最も大きい方向の長さを測定し、夫々の試料についての最大値を平均して求めた値である。 The fiber base material preferably has a mass per unit area of 100 to 500 g / m 2 , and more preferably 200 to 350 g / m 2 . Furthermore, the opening ratio, which is the ratio of the area occupied by the holes that are the gaps between the fibers in the total area of the fiber base material, is preferably 15 to 60%, and more preferably 20 to 50%. In addition, the representative dimension of the hole which is the gap between the fibers is preferably 0.5 to 5.0 mm, and more preferably 1.0 to 3.0 mm. In the present invention, the aperture ratio is a stereomicroscope (67 times magnification) of 20 4 mm square fiber substrate samples using an image processing machine (TV Image Processor EXCEL manufactured by Nippon Avionics Co., Ltd.) using Image Command 4198 software. It is the average value of the values for the respective fiber base samples that were measured and the pixel number ratio of the holes was determined. In addition, the representative dimension of the hole is determined by measuring the length in the direction in which the fiber-to-fiber gap is the largest in the hole of each fiber base sample by the same measurement method as the aperture ratio, and measuring the maximum dimension for each sample. It is a value obtained by averaging the values.

長繊維基材を上記のような範囲の単位面積当たりの質量、開口率、穴の代表寸法にすることにより、樹脂含浸性、剛性が一層優れ、より一層優れた特性を有する成形材料を得ることができる。   By making the long fiber base material have the mass per unit area in the above range, the aperture ratio, and the representative dimensions of the holes, a molding material having even better resin impregnation properties and rigidity and further excellent characteristics can be obtained. Can do.

本発明において、成形材料中の繊維基材の質量は、成形材料総質量に対し、繊維の種類により異なり得るが、例えば、ガラス繊維の場合には、成形材料全重量に対して、繊維20〜60重量%が好ましく、30〜50重量%がより好ましい。繊維の重量が20重量%未満であると、成形品の物性が低下したり、そりやうねりが大きくなる傾向にあり、60重量%を超すと、繊維に樹脂が未含浸となる傾向にある。その他の種類の繊維であっても、上記値を参考にしつつ、適宜配合割合を求めることができる。   In the present invention, the mass of the fiber base material in the molding material may vary depending on the type of fiber with respect to the total mass of the molding material. For example, in the case of glass fiber, the fiber 20 to 60 weight% is preferable and 30-50 weight% is more preferable. If the weight of the fiber is less than 20% by weight, the physical properties of the molded product tend to be reduced or warpage or undulation tends to increase. If the weight exceeds 60% by weight, the fiber tends to become unimpregnated. Even with other types of fibers, the blending ratio can be determined as appropriate with reference to the above values.

上記成形材料の形状は、装具本体を形成する場合には一般には板状である。例えば、平面又は曲面の板状である。また、一つ又は複数の穴を設けた板状であってもよい。なお、装具を補強するための補強用成形材料としては、板状又は棒状であってもよく、その形態は、例えば、扇状、テープ状、輪状、円弧状、円盤状等であってよい。上記成形材料の厚みは0.5〜5mmが好ましく、より好ましくは1〜3mmである。このため、非常に薄い材料で装具を作製することが可能であり、従来のプラスチック材料を使用した装具と異なり、装着性や意匠に優れている。しかも、後述するように、局所的に補強することが容易であるので、機能の点でも充分な性能を確保することができる。   The shape of the molding material is generally plate-shaped when the orthosis body is formed. For example, it is a flat or curved plate. Moreover, the plate shape provided with the 1 or several hole may be sufficient. The reinforcing molding material for reinforcing the brace may be a plate shape or a rod shape, and the form may be, for example, a fan shape, a tape shape, a ring shape, an arc shape, a disk shape, or the like. The thickness of the molding material is preferably 0.5 to 5 mm, more preferably 1 to 3 mm. For this reason, it is possible to produce a brace with a very thin material, and it is excellent in wearability and design unlike a brace using a conventional plastic material. In addition, as will be described later, since it is easy to reinforce locally, sufficient performance can be ensured in terms of function.

つぎに、本発明の製造方法を説明する。本発明の製造方法は、(a)上記成形材料(以下、本発明の製造方法の説明において、補強用成形材料をふくまない。)をポリカプロラクトンの融点以上、かつ120℃未満の温度に加熱して軟化させる工程、及び(b)上記工程(a)を経た成形材料を軟化状態を保ちつつ100℃以下の温度にて装着者の装着部位に沿わせることにより装着部位の形状に合わせて変形する工程、を含む。上記軟化させる工程(a)においては、軟化させる温度は、ポリカプロラクトンの融点以上で、かつ、120℃未満であり、上限は115℃程度がより好ましい。軟化させる温度が120℃を超えると成形材料を素手で取り扱うことが困難となり、また、加熱方法や加熱時間の観点から簡易に現場で実施することが困難となる。   Next, the production method of the present invention will be described. The production method of the present invention comprises: (a) heating the molding material (hereinafter not including the reinforcing molding material in the description of the production method of the present invention) to a temperature not lower than the melting point of polycaprolactone and lower than 120 ° C. And (b) the molding material that has undergone the above-mentioned step (a) is deformed according to the shape of the wearing part by keeping the softened state along the wearing part of the wearer at a temperature of 100 ° C. or lower. Process. In the softening step (a), the softening temperature is not less than the melting point of polycaprolactone and less than 120 ° C, and the upper limit is more preferably about 115 ° C. When the temperature for softening exceeds 120 ° C., it becomes difficult to handle the molding material with bare hands, and it is difficult to carry out it easily on site from the viewpoint of the heating method and the heating time.

上記変形する工程(b)は、100℃以下の温度で成形材料が軟化した状態で行うので、装着者の身体に直接又は衣服を介して間接に成形材料をあてがって形をとることができる。その際、曲げ、伸展等を含む変形が可能であり、踵等の深い変形であっても充分可能である。またその際、繊維自体も伸縮性の編物等を使用する等により、複合材料であっても変形の自由度が損なわれることはない。軟化した状態を保つための温度は、例えば、45℃程度(例えば、43℃〜47℃)、又はそれ以上、例えば、50℃程度(例えば、48℃〜52℃)又はそれ以上(例えば、80℃程度)、であってよく、必要に応じて100℃以下の温度範囲内で加熱することができる。なお、装着者の身体にあてがう前に、例えば、型等にあてて、予め大まかな変形を施しておくことも可能である。このような変形材料を予め作成しておき、現場にて装着者に合わせて成形するようにすれば、病院等の施設において多数の患者のために調製するうえで好都合である。   Since the deforming step (b) is performed in a state where the molding material is softened at a temperature of 100 ° C. or lower, the molding material can be applied directly to the wearer's body or indirectly through clothing. At that time, deformation including bending, extension and the like is possible, and even deep deformation such as wrinkles is sufficiently possible. At that time, the degree of freedom of deformation is not impaired even if the fiber itself is a composite material by using a stretch knitted fabric or the like. The temperature for maintaining the softened state is, for example, about 45 ° C. (for example, 43 ° C. to 47 ° C.) or more, for example, about 50 ° C. (for example, 48 ° C. to 52 ° C.) or more (for example, 80 ° C. The temperature may be about 0 ° C.), and may be heated within a temperature range of 100 ° C. or less as necessary. In addition, before applying to a wearer's body, it is also possible to apply a rough deformation | transformation beforehand, for example by applying to a type | mold. If such a deformable material is prepared in advance and molded in accordance with the wearer at the site, it is convenient for preparation for a large number of patients in a facility such as a hospital.

上記工程(a)及び工程(b)において、加熱は、任意の方法が適用できるが、熱風(例えば、ドライヤー等による)又は熱水等の加熱した液体や液体を含浸させた吸水性材料、ゲル等を利用することが可能であり、特別な加熱装置は不要である。例えば、熱水を利用する場合、流れる熱水(例えば、蛇口から流下する熱水)、容器に溜めた熱水、又は布等の吸水性材料に染み込ませた湿布等によれば、材料を全体に加熱することも、局所的に加熱することも容易である。また、ドライヤー等の熱風を利用する場合は、局所的に加熱することが容易である。このように、熱風や熱水を利用する場合は特別な装置は不要である。従って、現場で実施する場合に好適である。また、本発明の製造方法において、加熱のための装置、例えば、オーブン装置等を利用することも可能である。   In the step (a) and the step (b), any method can be applied for heating, but a heated liquid such as hot air (for example, with a dryer) or hot water or a water-absorbing material impregnated with a liquid, gel Etc., and a special heating device is not necessary. For example, when using hot water, according to the flowing hot water (for example, hot water flowing down from a faucet), hot water stored in a container, or a wet cloth soaked in a water-absorbing material such as cloth, the entire material It is easy to heat up locally or locally. Moreover, when using hot air, such as a dryer, it is easy to heat locally. Thus, no special device is required when hot air or hot water is used. Therefore, it is suitable when implemented on site. In the manufacturing method of the present invention, it is also possible to use an apparatus for heating, for example, an oven apparatus.

Even if a plurality of materials are locally laminated, the surface unevenness is slight.

本発明の製造方法を適用する装具としては特に限定はなく、下肢装具[例えば、短下肢装具(例えば、後面支持式、湯之児式、Teufel型、オルトップOMC型等)、キャストブレース等の整形外科的治療装具等]、上肢装具[例えば、肘固定装具、末梢神経損傷装具(例えば、正中神経麻痺装具、尺骨神経麻痺装具等)、マレット装具等]、又は、体幹装具(例えば、頸椎装具、側湾症装具等)等をあげることができる。   There are no particular limitations on the orthosis to which the production method of the present invention is applied, such as lower limb orthoses (for example, short lower limb orthoses (for example, rear support type, Yunoko type, Teufel type, Oltop OMC type, etc.), cast braces, etc. Orthopedic treatment devices, etc.], upper limb devices [eg, elbow fixation devices, peripheral nerve injury devices (eg, median nerve palsy devices, ulnar nerve palsy devices, etc.), mallet devices, etc.] or trunk devices (eg, cervical vertebrae) Such as orthoses, side bay orthoses, etc.).

本発明の下肢装具は、ポリカプロラクトンを有機又は無機の繊維に含浸させてなる板状又は棒状成形材料を加熱し軟化させた上記補強用成形材料を、ポリカプロラクトンと有機又は無機の繊維とからなり下肢の後面を固定支持する一体成形装具の内側又は外側表面の補強箇所に自着させ、上記一体成形装具を局所的に補強してなる下肢装具である。上記一体成形装具としては、本発明の製造方法で製造された後面支持式の短下肢装具等が挙げられる。このような下肢装具においては、筋肉や関節の動きに対応して、装具の撓み性や変形性を調節することが好ましい。そのために、本発明の下肢装具においては、板状又は棒状成形材料、好ましくはテープ状の上記補強用成形材料を、上記下肢装具の踵、ふくら脛及びくるぶしからなる群の少なくとも一つの部位に自着させ、局所的に補強用成形材料を追加的に積層する。その際、テーピング技術を応用して、力のかかる方向や変形を抑制したい方向に対応するように、踵、ふくら脛、くるぶし等の部位に貼り付けることが好ましい。テーピング技術は、関節、筋肉、靱帯、腱などの身体部位(例えば、手や足の指、手首、肩、肘、腰、大腿部、膝、足首、アキレス腱、踵、土踏まず等)に適用し、正常可動範囲を超えないようにテープで可動範囲外の動きを制限する手法である。この手法には、Xサポート(X字型に貼る方法)、フィギュアエイト(数字の8の字を描くように巻く方法)、スパイラル(らせん状に貼る手法)、ヒールロック(踵の内側と外側を斜めに横切るように貼る方法)等の公知の貼り方がある。また、スターアップ(アブミ型のテープ)、ホースシュー(馬蹄形のテープ)等の形状のテープも知られている。従って、装具の変形を抑制したい場合、動きを制限するこれらのテーピング技術を利用して、装具の局所的補強をすることが効果的である。   The lower limb orthosis of the present invention comprises the above-mentioned reinforcing molding material obtained by heating and softening a plate-like or rod-like molding material impregnated with polycaprolactone in organic or inorganic fibers, and comprising polycaprolactone and organic or inorganic fibers. The lower limb orthosis is formed by self-attaching to a reinforcing portion on the inner or outer surface of an integrally molded brace that fixedly supports the rear surface of the lower limb and locally reinforcing the integrally molded brace. Examples of the integrally molded orthosis include a back-supported short leg prosthesis manufactured by the manufacturing method of the present invention. In such lower limb orthosis, it is preferable to adjust the flexibility and deformability of the orthosis according to the movement of muscles and joints.

Self-adhering and locally laminating a reinforcing molding material locally. In that case, it is preferable to apply a taping technique to a part such as a heel, a calf, an ankle or the like so as to correspond to a direction in which force is applied or a direction in which deformation is desired to be suppressed. Taping technology is applied to body parts such as joints, muscles, ligaments, and tendons (eg, hands and toes, wrists, shoulders, elbows, hips, thighs, knees, ankles, Achilles tendons, heels, arches, etc.). This is a technique of limiting movement outside the movable range with tape so as not to exceed the normal movable range. This method includes X support (method of sticking in X shape), Figure Eight (method of winding like drawing the figure 8), spiral (method of sticking spirally), heel lock (inside and outside of the heel) There are known methods of pasting such as a method of pasting so as to cross diagonally. Tapes of shapes such as star-up (abumi-type tape) and horseshoe (horse-shoe-shaped tape) are also known. Therefore, when it is desired to suppress the deformation of the brace, it is effective to reinforce the brace locally using these taping techniques that limit the movement.

本発明の下肢装具は、補強用成形材料を局所的に、好ましくはテーピング技術を応用して増設することにより、可動域の違いや強度の違いを持つことができ、必要な部位を厚く、それ以外の部位は薄く成形することが容易にできる。   The lower limb orthosis of the present invention can have a difference in range of motion and a difference in strength by locally adding a reinforcing molding material, preferably by applying a taping technique, thickening a necessary part, Other parts can be easily formed thin.

(板状成形材料の作製)
つぎに、上記製造例1及び製造例2のワニスを夫々含浸槽に満たし、アクリルシラン処理を施した単位面積当たりの重量が240g/mのラッセル縦編みのガラス繊維編物を含浸槽内に浸してガラス繊維編物に前記ワニスを含浸させた。その後、乾燥機にて150℃で10分間乾燥させて、製造例1及び製造例2のシート状の成形材料を得た。このシート状の成形材料の厚みは1.5mmであった。また、上記シート状の成形材料の単位面積当たりの重量は、550g/mであり、シート状の成形材料の繊維含有率は44重量%であった。本製造例のガラス繊維編み物は繊維と繊維の間隙である穴の代表寸法が1.3mmであり、開口率は23%であり充分な通気性及び伸縮性を有していた。なお、シート状の成形材料の繊維含有率が20重量%未満になると、編み物の繊維と繊維の間隙は完全に樹脂でふさがり、逆にシート状の成形材料の繊維含有率が60重量%を超えると、樹脂が含浸していない箇所が発生した。
(Production of plate-shaped molding material)
Next, the impregnation tank is filled with the varnishes of Production Example 1 and Production Example 2, respectively, and a glass fiber knitted raschel warp knitted with an acrylic silane treatment and having a weight per unit area of 240 g / m 2 is immersed in the impregnation tank.

実施例1
製造例1及び製造例2で得られた成形材料を用いて、それぞれについて下記装具を作製した。
(1)シート状の成形材料を1層で使用した短下肢装具の製作
加熱温度:約80℃
加熱方法:上記温度の流水
装着部位に沿わせて変形させる際の材料の温度:約50℃
上記条件で成形材料を加熱し、下肢に沿わせて伸展変形させた。その後、材料の周囲をトリミングして後面支持式一体成形装具を成形した。
Example 1
Using the molding materials obtained in Production Example 1 and Production Example 2, the following appliances were produced.
(1) Production temperature of ankle foot orthosis using sheet-shaped molding material in one layer Heating temperature: about 80 ° C
Heating method: Temperature of the material when deforming along the flowing water mounting part at the above temperature: about 50 ° C
The molding material was heated under the above conditions and stretched and deformed along the lower limbs. Thereafter, the periphery of the material was trimmed to form a back support type integrally molded appliance.

従来、熱可塑性樹脂板を使用して成形した場合、作業者による肉厚のばらつきが生じたが、上記材料を使用した場合、均質な肉厚を得られた。また、熱可塑性樹脂のみを使用した場合に、冷却時に変形することが多く補正が必要であったが、上記材料を使用した場合は形状の変形がなかった。   Conventionally, when molding was performed using a thermoplastic resin plate, the thickness of the worker varied, but when the above materials were used, a uniform thickness was obtained. Further, when only the thermoplastic resin was used, it often deformed during cooling, and correction was necessary. However, when the above materials were used, there was no deformation of the shape.

(2)補強した短下肢装具の製作
装具の温度:約60℃の湿布で加温
補強材の加熱温度:約80℃
加熱方法:流水にて加温
自着させた方法:手掌の圧力程度の加圧
上記条件で、上記(1)で製作した後面支持式一体成形装具の踵から上部にかけて扇形の成形材料(補強材)を自着させた。
(2) Production of reinforced short leg orthosis Temperature of the orthosis: Heating temperature of the reinforcing material heated by a compress of about 60 ° C: About 80 ° C
Heating method: Method of heating and self-adhesion with running water: Pressurization of about the pressure of the palm Under the above conditions, a fan-shaped molding material (reinforcing material) from the heel to the upper part of the rear-supporting integrally molded device manufactured in (1) ).

その結果、足部には柔らかさを残したまま、ふくら脛部だけを補強することができた。この方法により、従来、経験則で行っていた強度補正を、正確で容易に再現可能な方法で実現可能であることがわかった。   As a result, it was possible to reinforce only the calf shin part while leaving the foot part soft. By this method, it has been found that the intensity correction that has been conventionally performed based on the empirical rule can be realized by an accurate and easily reproducible method.

(3)テーピングを応用して補強した短下肢装具の製作
装具の温度:約60℃の湿布で加温
補強材の加熱温度:約80℃
加熱方法:流水にて加温
自着させた方法:手掌の圧力程度の加圧
上記条件で、上記(1)で製作した後面支持式装具の踵周り、ふくら脛、下肢側面を、テーピング技術を応用してテープ状の補強用成形材料を自着させた。図1にその様子を示した。図1左図に示すテープ状補強用成形材料(輪状と馬蹄形を示した。)と後面支持式下肢装具を使用し、図1右図は補強した状態を示す。

This is shown in FIG. A tape-shaped reinforcing molding material (shown in a ring shape and a horseshoe shape) and a rear support lower limb orthosis shown in the left diagram of FIG. 1 are used, and the right diagram of FIG. 1 shows a reinforced state.

補強部分と非補強部分で撓りと支持性に明らかな違いがあった。この方法により、例えば、筋肉の動きに対してより一層制限をかけたい箇所を局所的に補強することにより、左右への捩れの制限に違いを持たせることができた。その結果、従来では単一素材で、方向性の不明な撓りを応用して人体の動きに合わせていたが、局所的に容易に補強可能なこの方法により、可動域の違いや強度の違いという機能を付与した装具を作製可能となった。しかも、それを、湯を使用して、簡易容易に実施可能であった。   There was a clear difference in flexure and support between the reinforced and non-reinforced parts. By this method, for example, by locally reinforcing a portion where it is desired to further restrict the movement of muscles, it was possible to make a difference in the restriction of twisting to the left and right. As a result, in the past, a single material was used to adapt to the movement of the human body by applying bending with unknown directionality, but with this method that can be easily reinforced locally, differences in range of motion and differences in strength It became possible to produce an orthosis with the function. Moreover, it could be easily and easily performed using hot water.

(4) Manufacturing heating temperature of mallet orthosis: about 80 ° C
Heating method: Temperature of material when deforming along flowing fingers with running water: about 45 ° C
Under the above conditions, a brace was created to prevent the right-hand index finger from bending. A square plate-shaped molding material was deformed so as to be wrapped along the index finger. After cooling and solidification, the surroundings were trimmed, and the part where the joint on the ventral side of the finger hit was removed. Fig. 2 shows the manufactured orthosis.

出来上がった装具は、ポリプロピレン製やポリエチレン製、又は、ポリカプロラクトン単独製に較べて狭面積での支持が可能であった。
なお、製造例1で得られたワニスを使用した成形材料の場合は成形時の加熱による自着に優れ、製造例2で得られたワニスを使用した場合は、成形時の加熱による表面の粘着感がなく、強度に優れた装具を得ることができた。
The finished orthosis could be supported in a smaller area than polypropylene, polyethylene, or polycaprolactone alone.
In addition, in the case of the molding material using the varnish obtained in Production Example 1, it is excellent in self-adhesion by heating at the time of molding, and in the case of using the varnish obtained in Production Example 2, surface adhesion by heating at the time of molding. There was no feeling and an appliance with excellent strength could be obtained.
