 しかしながら、上述のベルト型電極の場合、ベルト型電極の長手方向において電気抵抗が異なるため、電極端子から離隔する程電流密度が小さくなり、得られる電気刺激が弱くなってしまう。ベルト型電極の端部において良好な電気刺激を得るためには、出力を上げる必要があるが、出力が上がると、電極端子付近での電気刺激が強くなり、使用者に不快感を与える。そこで、本願発明は、人体に電気刺激を付与する帯状の電気刺激用装着具において、電流密度のバラツキを抑制することを目的とする。 However, in the case of the above-described belt-type electrode, since the electric resistance is different in the longitudinal direction of the belt-type electrode, the current density decreases as the distance from the electrode terminal decreases, and the obtained electrical stimulation becomes weak. In order to obtain good electrical stimulation at the end of the belt-type electrode, it is necessary to increase the output, but when the output increases, the electrical stimulation in the vicinity of the electrode terminal becomes strong, giving the user unpleasant feeling.

An R-shaped portion 13 a is formed at a location where the long main body portion 11 and the second protruding piece portion 13 are connected. By forming these R- shaped portions 12a and 13a, the rigidity of the metal plate 10 can be increased. Titanium can be used for the metal plate 10.
 図5を参照して、金属板10の前記長尺方向における略中央には、外周面にネジ溝を有するネジ部(突出部に相当する)14が形成されている。ネジ部14は、金属板10の板厚方向に延びており、電極端子15が締結されている。電極端子15がネジ部14に締結されることにより、金属板10及び電極端子15が導通する。なお、ネジ部14はネジ溝を有しない突出部であってもよい。この場合、カシメ手段を用いて該突出部及び電極端子15を固定することができる。 Referring to FIG. 5, a screw portion (corresponding to a protruding portion) 14 having a screw groove on the outer peripheral surface is formed at substantially the center in the longitudinal direction of the metal plate 10.

 保持層20の一方の面には、小面ファスナー60が設けられており(図1参照)、保持層20の他方の面には、大面ファスナー70が設けられている(図3参照)。小面ファスナー60の大面ファスナー70に対する脱着位置を調整することにより、電気刺激用装着具1を所望の刺激部位に装着することができる。 A small surface fastener 60 is provided on one surface of the holding layer 20 (see FIG. 1), and a large surface fastener 70 is provided on the other surface of the holding layer 20 (see FIG. 3). By adjusting the attachment / detachment position of the small surface fastener 60 with respect to the large surface fastener 70, the electrical stimulation attachment device 1 can be attached to a desired stimulation site.
 次に、電気刺激用装着具1の使用方法について説明する。本実施形態の電気刺激用装着具1は、正極タイプと、負極タイプとが対になって使用される。正極タイプの電気刺激用装着具1を刺激部位に装着し、負極タイプの電気刺激用装着具1を他の刺激部位に装着し、これらの電気刺激用装着具1の各電極端子15に電気信号出力装置(不図示)から延びるコードを接続することにより、電気刺激を付与することができる。刺激部位は、例えば、足首、膝上、腰であってもよい。また、刺激部位は、複数箇所であってもよい。例えば、4個の電気刺激用装着具1を用いて、左右の足首、左右の膝上を刺激することができる。また、3個の電気刺激用装着具1を用いて、それぞれを腰部、膝上及び足首に装着してもよい。この場合、膝上に装着される電気刺激用装着具1の極性を正極、腰部及び足首に装着される電気刺激用装着具1の極性を負極にすることができる。 Next, how to use the electrical stimulation wearing device 1 will be described. The electrical stimulation wearing device 1 of the present embodiment is used in pairs of a positive electrode type and a negative electrode type. The positive-type electrical stimulation wearing device 1 is attached to a stimulation site, the negative-type electrical stimulation wearing device 1 is attached to another stimulation site, and an electrical signal is applied to each electrode terminal 15 of these electrical stimulation wearing devices 1. Electrical stimulation can be applied by connecting a cord extending from an output device (not shown). The stimulation site may be, for example, an ankle, above the knee, or waist. Further, the stimulation site may be a plurality of locations. For example, it is possible to stimulate the left and right ankles and the left and right knees using the four electrical stimulation wearing devices 1. Moreover, you may mount | wear each with a waist | hip | lumbar part, a knee top, and an ankle using the three mounting devices 1 for electrical stimulation. In this case, the polarity of the electrical stimulation wearing device 1 mounted on the knee can be the positive polarity, and the polarity of the electrical stimulation mounting device 1 mounted on the waist and ankle can be the negative polarity.
 ここで、本実施形態の金属板10は、第1突出片部12及び第2突出片部13を互い違いに形成した千鳥形状に構成されているため、電気刺激用装着具1の柔軟性を高めることができる。これにより、電気刺激用装着具1を屈曲させて、所望の刺激部位に密着させやすくすることができる。 Here, since the metal plate 10 of this embodiment is configured in a staggered shape in which the first protruding piece portions 12 and the second protruding piece portions 13 are alternately formed, the flexibility of the electrical stimulation wearing device 1 is increased. be able to. Thereby, the mounting device 1 for electrical stimulation can be bent and it can be made to adhere | attach easily on a desired stimulation site | part.
 金属板10を千鳥状に形成して電流経路を狭めた場合、電気抵抗が上昇して発熱するおそれがあるため、通常、導電板としての金属板10は平板形状に形成される。しかしながら、EMSの場合、出力が低いため、金属板10を千鳥状に形成しても、使用者に不快感を与える程の発熱は起こらない。すなわち、本願発明は、金属板10を千鳥状に形成するという技術常識から容易に想到できない知見に基づき、創作されている。 When the current path is narrowed by forming the metal plates 10 in a zigzag shape, the electrical resistance may increase and heat may be generated. Therefore, the metal plate 10 as a conductive plate is usually formed in a flat plate shape. However, in the case of EMS, since the output is low, even if the metal plates 10 are formed in a staggered pattern, heat generation that causes discomfort to the user does not occur. That is, the present invention has been created based on the knowledge that cannot be easily conceived from the technical common sense that the metal plates 10 are formed in a staggered pattern.
 また、ゴム電極の代わりに帯状に延びる金属板10を用いることにより、長尺方向における電気抵抗のバラツキが抑制される。これにより、長尺方向における電気刺激が安定化して、良好な電気刺激を付与することができる。 Further, by using the metal plate 10 extending in a strip shape instead of the rubber electrode, variation in electric resistance in the longitudinal direction is suppressed. Thereby, the electrical stimulation in the elongate direction is stabilized and a favorable electrical stimulation can be provided.
 また、図2に図示するように、寸法X1及び隙間Y0を略等しく、寸法Y1及び隙間X0を略等しく形成することにより、金属板10の短尺方向の寸法が全ての領域において略等しくなるため、長尺方向のみならず短尺方向の電気抵抗のバラツキをも抑制することができる。これにより、より良好な電気刺激を付与することができる。 Further, as shown in FIG. 2, by forming the dimension X1 and the gap Y0 substantially equal and the dimension Y1 and the gap X0 substantially equal, the dimension in the short direction of the metal plate 10 becomes substantially equal in all regions. Variations in electrical resistance not only in the long direction but also in the short direction can be suppressed. Thereby, better electrical stimulation can be provided.
 また、図2に図示するように、凹凸の位相をずらして金属板10を打ち抜くことにより、金属材料のロスを無くしてコストを削減することができる。 Further, as shown in FIG. 2, the metal plate 10 is punched by shifting the phase of the projections and depressions, so that the loss of the metal material can be eliminated and the cost can be reduced.
 また、人体に接触する面に不織布シート30が配置されることにより、親水性の膜が形成されるため、刺激感覚をソフトにすることができる。不織布シート30を挟圧部50に対して着脱可能に装着することにより、不織布シート30の交換が容易になり、衛生面を向上させることができる。 Moreover, since the hydrophilic film is formed by disposing the nonwoven fabric sheet 30 on the surface that comes into contact with the human body, the stimulation sensation can be softened. By attaching the nonwoven fabric sheet 30 to the pinching part 50 so as to be detachable, the nonwoven fabric sheet 30 can be easily replaced, and the hygiene aspect can be improved.
