Description
本発明は、脹脛に巻装される身体着用具であって、足の疲れ、むくみ、冷え症等の症状の予防又は改善に有効な身体着用具に関する。 The present invention relates to a body-worn device that is wound around a calf and is effective in preventing or improving symptoms such as fatigue, swelling, and coldness of feet.
現代社会では、車社会によって歩く機会が減り、運動量が減少傾向にあり、また長時間の立ち仕事やデスクワーク等に従事している人が多いこともあって、脚の疲れ、むくみ、冷え症等の症状に悩まされている人が増加している。 In modern society, there are fewer opportunities to walk due to the automobile society, the amount of exercise tends to decrease, and there are many people who are engaged in long standing work or desk work, etc., such as leg fatigue, swelling, coldness, etc. An increasing number of people are suffering from symptoms.
従来、足の疲れ、むくみ、冷え症等の症状の予防又は改善を目的として、脹脛における筋ポンプ作用を増強させるためのストッキングやレギンス等の下腿部用の弾性衣類が種々提案されている。例えば、特許文献１には、脚の各部位毎に段階的に着圧を変化させることによって脚部の血行を促進させ得るパンティストッキングが開示されている。また、特許文献２には、少なくとも下腿部を含む脚部を有する衣類において、脚部を足長方向に緊締力が異なる複数の輪状の部位から構成し、着用時の着用者の脚部表面への着圧が下腿部最大径部において最大となるように設定し、且つ下腿部最大径部、立位大腿最小部、及び下腿部最小径部を所定の範囲に設定することにより、脚部のむくみや血行障害を軽減させ得ることが開示されている。 Conventionally, various elastic garments for the lower leg such as stockings and leggings for enhancing the muscle pump action in the calf have been proposed for the purpose of preventing or improving symptoms such as fatigue, swelling, and coldness of the feet. For example, Patent Literature 1 discloses a pantyhose that can promote blood circulation of the leg by changing the wearing pressure in stages for each part of the leg. Further, in Patent Document 2, in a garment having at least a leg part including a lower leg part, the leg part is composed of a plurality of ring-shaped parts having different tightening forces in the foot length direction, and the wearer's leg surface when worn By setting the maximum pressure at the crus maximum diameter part and setting the crus maximum diameter part, standing thigh minimum part, and crus minimum diameter part within a predetermined range It is disclosed that leg swelling and blood circulation disorder can be reduced.
一方、脚の疲れ、むくみ、冷え症等の症状は、下腿部の静脈圧が増加し、血行が悪化することが一因となっていることが分かっている。そのため、これらの症状の予防又は改善には、下腿部の筋肉収縮により血管を圧迫し、静脈環流を促進させる筋ポンプ作用を増強させることが重要である。特に、脹脛における筋ポンプ作用は静脈環流の促進に大きく寄与しているため、前記症状の予防又は改善には、脹脛における筋ポンプ作用を効果的に増強することが有効になると考えられている。 On the other hand, it is known that symptoms such as leg fatigue, swelling, and coldness are caused by increased venous pressure in the lower leg and worsening blood circulation. Therefore, in order to prevent or ameliorate these symptoms, it is important to enhance the muscle pump action that presses blood vessels by muscular contraction of the lower leg and promotes venous perfusion. In particular, since the muscle pump action in the calf greatly contributes to the promotion of venous perfusion, it is considered that effectively enhancing the muscle pump action in the calf is effective in preventing or improving the above symptoms.
しかしながら、前記症状の予防又は改善を目的として開発されている従来の下腿部用の弾性衣類では、静脈環流の促進効果がある程度認められるものの、近年、前記症状の予防又は改善効果をより強く実感したいという使用者の要望が高まっており、従来の下腿部用の弾性衣類では、このような使用者の要望を必ずしも満足できなくなっている。 However, the conventional elastic clothing for the lower leg developed for the purpose of preventing or ameliorating the above symptoms has a certain effect of promoting venous perfusion, but in recent years, the effect of preventing or ameliorating the above symptoms has become stronger. The user's desire to do so has increased, and the conventional elastic garment for the lower leg cannot always satisfy such a user's request.
このような従来技術を背景として、身体に着用するという簡便な手法により、前記症状を効果的に予防又は改善効できる製品の開発が切望されている。 With such a conventional technology as a background, development of a product that can effectively prevent or ameliorate the above symptoms by a simple method of wearing on the body is eagerly desired.
本発明は、静脈環流を促進させ、足の疲れ、むくみ、冷え症等の症状を効果的に予防又は改善できる身体着用具を提供することを目的とする。 An object of the present invention is to provide a body wear device that promotes venous perfusion and can effectively prevent or ameliorate symptoms such as foot fatigue, swelling, and coldness.
本発明者らは、前記課題を解決すべく鋭意検討を行ったところ、伸長率が１０〜３０％である素材を選択し、これを下腿部の周囲に当接させ装着することによって、静脈環流を促進させ、足の疲れ、むくみ、冷え症等の症状を効果的に予防又は改善できることを見出した。本発明は、かかる知見に基づいて、更に検討を重ねることにより完成したものである。 The inventors of the present invention have intensively studied to solve the above-mentioned problems. As a result, a material having an elongation rate of 10 to 30% is selected, and the material is placed in contact with the periphery of the lower leg, thereby attaching the vein. The present inventors have found that it is possible to promote reflux and effectively prevent or ameliorate symptoms such as foot fatigue, swelling and coldness.

本発明の身体着用具は、下腿部に装着される身体着用具であって、下腿部の周囲に当接される本体部と、前記本体部を下腿部の周囲に当接した状態で保持させる取付部とを備え、前記本体部の伸長率が１０〜３０％であることを特徴とする。以下、本発明の身体着用具について詳述する。 The body wearing device of the present invention is a body wearing device to be attached to the lower leg part, and a state in which the body part is brought into contact with the circumference of the lower leg part and the body part is brought into contact with the circumference of the lower leg part And an extension part of the main body part is 10 to 30%. Hereinafter, the body wear tool of the present invention will be described in detail.
本発明の身体着用具において、前記本体部は、着用者の下腿部の周囲に当接される部位であり、その形状については、下腿部の周囲に当接できる形状であればよく、着用者の年齢や性別等に応じて適宜設定される。 In the body wear device of the present invention, the main body part is a part that comes into contact with the circumference of the lower leg of the wearer, and the shape thereof may be any shape that can come into contact with the circumference of the lower leg, It is set as appropriate according to the age and sex of the wearer.
また、前記本体部は、伸長率が１０〜３０％であり、このような伸長率を充足することにより、静脈環流を効果的に促進して、足の疲れ、むくみ、冷え症等の症状を予防又は改善することが可能になる。静脈環流をより一層効果的に促進させ、足の疲れ、むくみ、冷え症等の症状の予防又は改善効果をより一層高めるという観点から、前記本体部の伸長率は、好ましくは１５〜３０％、更に好ましくは２０〜３０％が挙げられる。ここで、伸長率は、チャック幅３０ｍｍ、チャック間距離Ｌを１００ｍｍとして、試験片を引張速度５００ｍｍ／分で荷重４．０ｋｇをかけて引っ張った際の伸びＥを測定し、測定された伸びＥ（ｍｍ）とチャック間距離Ｌ（ｍｍ）を用いて、下記式（１）に従って算出される。
伸長率（％）＝（Ｅ／Ｌ）×１００ （１）
In addition, the body part has an elongation rate of 10 to 30%, and by satisfying such an elongation rate, venous perfusion is effectively promoted to prevent symptoms such as foot fatigue, swelling and coldness. Or it becomes possible to improve. From the viewpoint of promoting venous perfusion more effectively, and further enhancing the effect of preventing or improving symptoms such as foot fatigue, swelling, and coldness, the elongation rate of the main body is preferably 15 to 30%, and more preferably Preferably 20-30% is mentioned. Here, the elongation rate was measured by measuring the elongation E when the test piece was pulled with a load of 4.0 kg at a tensile speed of 500 mm / min with a chuck width of 30 mm and a distance L between chucks of 100 mm. Using (mm) and the distance L (mm) between chucks, it is calculated according to the following formula (1).
Elongation rate (%) = (E / L) × 100 (1)
また、前記本体部において、その伸び硬度（stiffness）については、特に制限されないが、静脈環流をより一層効果的に促進させるという観点から、収縮・弛緩期圧差が１２〜１５ｍｍＨｇ、好ましくは１３〜１５ｍｍＨｇ、更に好ましくは１４〜１５ｍｍＨｇが挙げられる。ここで、伸び硬度とは、２０歳代女性標準体型データに基づいた足ダミーの下腿部の踝よりも上の部位（周囲長２１．５ｃｍ）に、圧迫圧測定初期値が１０ｍｍＨｇを超えない範囲で、試験片（縦１９０ｍｍ、横４８０ｍｍ）を包囲して固定し、該足ダミーの周径を１ｃｍ増大させた際に生じる圧迫圧の増加分（ｍｍＨｇ）である。具体的には、図１に示す装置を用いて計測され、圧迫圧は衣服圧測定器を用いて測定される。 In the main body, the elongation hardness (stiffness) is not particularly limited, but from the viewpoint of more effectively promoting venous perfusion, the systolic / relaxation pressure difference is 12 to 15 mmHg, preferably 13 to 15 mmHg. More preferably, 14-15 mmHg is mentioned. Here, the elongation hardness means that the initial value of the pressure measurement does not exceed 10 mmHg at a site (periphery length: 21.5 cm) above the lower leg of the leg dummy based on the standard body shape data of women in their 20s. This is an increase (mmHg) in the compression pressure generated when the test piece (190 mm long and 480 mm wide) is surrounded and fixed and the circumference of the leg dummy is increased by 1 cm. Specifically, it is measured using the apparatus shown in FIG. 1, and the compression pressure is measured using a clothing pressure measuring device.
また、静脈環流をより一層効果的に促進させるという観点から、本発明の身体着用具を下腿部に装着した際の収縮・弛緩期圧差が１２〜１５ｍｍＨｇ、好ましくは１３〜１５ｍｍＨｇ、更に好ましくは１４〜１５ｍｍＨｇとなるように設定されていることが望ましい。ここで、収縮・弛緩期圧差とは、足関節最大背屈運動を行った際に下腿内側で収縮期と弛緩期の圧迫圧の差であり、本発明の身体着用具を脹脛部に圧迫圧が１０ｍｍＨｇ以下となるように装着した状態で足関節最大背屈運動を行って、収縮期と弛緩期の圧迫圧を衣服圧測定器にて測定することにより求められる値である。具体的には、図２に示す装置を用いて計測され、圧迫圧は衣服圧測定器を用いて測定される。 Further, from the viewpoint of more effectively promoting venous perfusion, the contraction / relaxation pressure difference when the body wearing device of the present invention is attached to the lower leg is 12 to 15 mmHg, preferably 13 to 15 mmHg, more preferably It is desirable to set it to be 14 to 15 mmHg. Here, the contraction / relaxation pressure difference is the difference between the compression pressure of the contraction phase and the relaxation phase on the inner side of the lower leg when the ankle joint maximum dorsiflexion is performed. This is a value obtained by performing ankle maximal dorsiflexion while wearing so that the pressure becomes 10 mmHg or less, and measuring the compression pressure during the systole and relaxation periods with a clothing pressure measuring instrument. Specifically, it is measured using the apparatus shown in FIG. 2, and the compression pressure is measured using a clothing pressure measuring device.
