Description

本発明は、心電図、筋電図、眼電図、脳波などの生体信号を検出するための生体用電極、および生体用電極アセンブリに関するものである。   The present invention relates to a biological electrode for detecting a biological signal such as an electrocardiogram, an electromyogram, an electrooculogram, and an electroencephalogram, and a biological electrode assembly.

心電図、筋電図、眼電図、脳波などの生体信号を検出するための生体用電極は、従来、ステンレス、プラチナ、銀電極、銀／塩化銀電極などの金属電極から構成されている。このような金属電極を用いて心電図などを計測する際には、肌にゼリー状の電解質を塗布して金属電極と肌との親和性を高め入力抵抗を下げることにより、ノイズの低減を図っている。   Conventionally, biological electrodes for detecting biological signals such as electrocardiograms, electromyograms, electrocardiograms, and electroencephalograms are composed of metal electrodes such as stainless steel, platinum, silver electrodes, and silver / silver chloride electrodes. When measuring electrocardiograms using such metal electrodes, noise is reduced by applying a jelly-like electrolyte to the skin to increase the affinity between the metal electrode and the skin and lower the input resistance. Yes.

しかしながら、肌にゼリー状の電解質を塗布した場合には、その塗布に手間がかかるという問題点がある。また、心電図などを計測した後、金属電極や肌からゼリー状の電解質を拭き取る必要があり、このような点でも、手間がかかるという問題点がある。さらに、ゼリー状の電解質を長期保管した場合には、変質や衛生面でも問題である。さらにまた、ステンレス、プラチナ、銀電極、銀／塩化銀電極などは、人によっては金属アレルギーを起こす場合もある。   However, when a jelly-like electrolyte is applied to the skin, there is a problem that the application takes time. Moreover, after measuring an electrocardiogram etc., it is necessary to wipe off a jelly-like electrolyte from a metal electrode or skin, and also in this respect, there is a problem that it takes time and effort. Furthermore, when the jelly-like electrolyte is stored for a long period of time, it is a problem in terms of alteration and hygiene. Furthermore, stainless steel, platinum, silver electrodes, silver / silver chloride electrodes, etc. may cause metal allergy in some people.

以上の問題点に鑑みて、本発明の課題は、ゼリー状の電解質を用いなくても、心電図などの生体信号を正確に検出可能な生体用電極、および生体用電極アセンブリを提供することにある。   In view of the above problems, an object of the present invention is to provide a living body electrode and a living body electrode assembly capable of accurately detecting a biological signal such as an electrocardiogram without using a jelly-like electrolyte. .

上記課題を解決するために、本発明では、心電図、筋電図、眼電図、脳波などの生体信号を検出するための生体用電極において、肌と接する電極部分を有機導電性ポリマーによって構成することを特徴とする。   In order to solve the above-mentioned problems, in the present invention, an electrode part in contact with the skin is formed of an organic conductive polymer in a biological electrode for detecting a biological signal such as an electrocardiogram, electromyogram, electrooculogram, and electroencephalogram. It is characterized by that.

本発明に係る生体用電極では、肌と接する電極部分が有機導電性ポリマーによって構成されているので、金属電極と比較して肌などとの親和性が高い。従って、本発明に係る生体用電極については、肌に直接接触させた場合でも、金属電極を肌に直接接触させた場合と比較してノイズを大幅に低減できる。従って、心電図などを計測する際、肌にゼリー状の電解質を塗布する必要がないので、心電図などを迅速に計測できる。また、心電図などを計測した後、金属電極および肌からゼリー状の電解質を拭き取る必要がないので、手間がかからない。しかも、心電図などを計測した後、単にアルコールで清掃するだけで何回も使用することができる。   In the biomedical electrode according to the present invention, since the electrode portion in contact with the skin is composed of an organic conductive polymer, the affinity with the skin or the like is higher than that of the metal electrode. Therefore, in the case of the biomedical electrode according to the present invention, noise can be greatly reduced even when the electrode is in direct contact with the skin as compared with the case where the metal electrode is in direct contact with the skin. Therefore, when measuring an electrocardiogram or the like, it is not necessary to apply a jelly-like electrolyte to the skin, so that the electrocardiogram or the like can be measured quickly. Moreover, since it is not necessary to wipe off the jelly-like electrolyte from the metal electrode and the skin after measuring an electrocardiogram or the like, it is not time-consuming. Moreover, after measuring an electrocardiogram or the like, it can be used many times simply by cleaning with alcohol.

本発明において、前記有機導電性ポリマーには、導電性粉体が添加されていることが好ましい。このように構成すると、有機導電性ポリマーの電気的抵抗をさらに低減することができる。   In the present invention, it is preferable that a conductive powder is added to the organic conductive polymer. If comprised in this way, the electrical resistance of an organic conductive polymer can further be reduced.

本発明において、前記導電性粉体として、Ｎｂ（ニオブ）およびＮｂＯ（一酸化ニオブ）のうちの少なくとも一方の粉体が前記有機導電性ポリマーに添加されていることが好ましい。ＮｂおよびＮｂＯをフィラーとして添加すると、有機導電性ポリマーの電気的抵抗を低減することができる。また、ＮｂおよびＮｂＯは、Ｔｉ（チタン）などと比較しても生体との親和性が高いので、肌などとの親和性が高い。また、Ｎｂ、ＮｂＯは、人体に全く毒性が無く、金属アレルギーは全く起こさないという利点がある。   In the present invention, it is preferable that at least one of Nb (niobium) and NbO (niobium monoxide) is added to the organic conductive polymer as the conductive powder. When Nb and NbO are added as fillers, the electrical resistance of the organic conductive polymer can be reduced. In addition, Nb and NbO have a high affinity with a living body even when compared with Ti (titanium) and the like, and thus have a high affinity with skin and the like. Further, Nb and NbO have the advantage that there is no toxicity to the human body and no metal allergy is caused.

本発明を適用した生体用電極と、該生体用電極に電気的に接続するリード線とを備えた生体用電極アセンブリにおいて、前記リード線は、複数本の金属線から形成され、前記生体用電極は、前記リード線の端部で前記複数本の金属線を広げた部分に前記有機導電性ポリマーを被覆してなることが好ましい。このように構成すると、製造工程を簡素化できるので、生体用電極アセンブリを安価に製造できる。それ故、医療施設において心電図を形成するときに使用する生体用電極アセンブリの他、家庭などで用いる心電計の生体用電極アセンブリに適している。   In a biological electrode assembly comprising a biological electrode to which the present invention is applied and a lead wire electrically connected to the biological electrode, the lead wire is formed of a plurality of metal wires, and the biological electrode Preferably, the organic conductive polymer is coated on a portion where the plurality of metal wires are extended at the end of the lead wire. If comprised in this way, since a manufacturing process can be simplified, the biological electrode assembly can be manufactured cheaply. Therefore, it is suitable not only for a living body electrode assembly used for forming an electrocardiogram in a medical facility but also for a living body electrode assembly for an electrocardiograph used at home or the like.

本発明を適用した生体用電極と、該生体用電極に電気的に接続するリード線とを備えた生体用電極アセンブリにおいて、前記リード線と前記生体用電極とは着脱自在であることが好ましい。このように構成すると、生体用電極のみを交換できるという利点がある。   In a biological electrode assembly including a biological electrode to which the present invention is applied and a lead wire electrically connected to the biological electrode, the lead wire and the biological electrode are preferably detachable. If comprised in this way, there exists an advantage that only the electrode for biological bodies can be exchanged.

本発明に係る生体用電極では、肌と接する電極部分が有機導電性ポリマーによって構成されているので、金属電極と比較して肌などとの親和性が高い。従って、本発明に係る生体用電極については、心電図などを計測する際、肌にゼリー状の電解質を塗布する必要がないので、心電図などを迅速に計測できる。また、心電図などを計測した後、金属電極および肌からゼリー状の電解質を拭き取る必要がないので、手間がかからない。しかも、心電図などを計測した後、単にアルコールで清掃すれば、何回も使用することができ、経済的である。また、ゼリー状の電解質を長期保管した場合に発生する変質や衛生面での問題を解消できる。さらに、ゼリー状の電解質や金属電極を用いないので、ゼリー状の電解質や金属電極が肌に合わない人についても安心して心電図などを計測することができる。   In the biomedical electrode according to the present invention, since the electrode portion in contact with the skin is composed of an organic conductive polymer, the affinity with the skin or the like is higher than that of the metal electrode. Therefore, with the biomedical electrode according to the present invention, when measuring an electrocardiogram or the like, it is not necessary to apply a jelly-like electrolyte to the skin, so that the electrocardiogram or the like can be measured quickly. Moreover, since it is not necessary to wipe off the jelly-like electrolyte from the metal electrode and the skin after measuring an electrocardiogram or the like, it is not time-consuming. Moreover, after measuring an electrocardiogram or the like, if it is simply cleaned with alcohol, it can be used many times and is economical. In addition, it is possible to eliminate deterioration and hygiene problems that occur when a jelly-like electrolyte is stored for a long period of time. Furthermore, since no jelly-like electrolyte or metal electrode is used, an electrocardiogram or the like can be measured with peace of mind even for a person whose jelly-like electrolyte or metal electrode does not fit the skin.

図面を参照して、本発明の実施の形態を説明する。   Embodiments of the present invention will be described with reference to the drawings.

［実施の形態１］
図１（Ａ）、（Ｂ）は、本発明の実施の形態１に係る生体用電極の外観図、およびその内部構造を示す断面図である。図２（Ａ）、（Ｂ）、（Ｃ）はそれぞれ、従来の金属電極をゼリー状の電解質を塗布せずに使用した場合、従来の金属電極をゼリー状の電解質を塗布して使用した場合、および本形態の生体用電極をゼリー状の電解質を塗布せずに使用した場合の筋電図の計測結果を示す説明図である。 [Embodiment 1]
1A and 1B are an external view and a cross-sectional view showing the internal structure of a biological electrode according to Embodiment 1 of the present invention. 2A, 2B, and 2C, respectively, when a conventional metal electrode is used without applying a jelly-like electrolyte, and when a conventional metal electrode is used with a jelly-like electrolyte applied. It is explanatory drawing which shows the measurement result of the electromyogram at the time of using the biomedical electrode of this form, and without apply | coating a jelly-like electrolyte.

図１（Ａ）、（Ｂ）において、本形態の生体用電極アセンブリ１は、心電図、筋電図、眼電図、脳波などの生体信号を測定するためのものであり、ディスク型の生体用電極２、リード線３、および端子４を備えている。   1A and 1B, a biological electrode assembly 1 according to the present embodiment is for measuring biological signals such as an electrocardiogram, an electromyogram, an electrooculogram, an electroencephalogram, and the like. An electrode 2, a lead wire 3, and a terminal 4 are provided.

生体用電極２は、リード線３が電気的に接続された金属電極２１と、この金属電極２１の表面に積層された有機導電性ポリマー層２０と、金属電極２１および有機導電性ポリマー層２０を覆う外装樹脂層２３とから構成されており、心電図を測定する際、有機導電性ポリマー層２０が肌に接触することになる。   The biological electrode 2 includes a metal electrode 21 to which the lead wire 3 is electrically connected, an organic conductive polymer layer 20 laminated on the surface of the metal electrode 21, and the metal electrode 21 and the organic conductive polymer layer 20. It is comprised from the exterior resin layer 23 to cover, and when measuring an electrocardiogram, the organic conductive polymer layer 20 will contact skin.

ここで、有機導電性ポリマー層２０は、ピロール系重合体、アニリン系重合体、チオフェン系重合体、アセチレン系重合体、フェニレン系重合体、フェニレンビニレン系重合体、アセン系重合体などの高分子マトリクス中に、ハロゲン系、ルイス酸系、プロトン酸系、遷移金属ハライド系などのドーパントをドープしたものであり、優れた導電性を示す。   Here, the organic conductive polymer layer 20 is a polymer such as a pyrrole polymer, an aniline polymer, a thiophene polymer, an acetylene polymer, a phenylene polymer, a phenylene vinylene polymer, or an acene polymer. The matrix is doped with a dopant such as a halogen type, Lewis acid type, proton acid type, or transition metal halide type, and exhibits excellent conductivity.

このように構成した生体用電極２では、肌と接する電極部分が有機導電性ポリマー層２０によって構成されているので、金属電極と比較して肌などとの親和性が高い。従って、本発明に係る生体用電極２については、心電図などを計測する際、肌にゼリー状の電解質を塗布する必要がないので、心電図などを迅速に計測できる。   In the biological electrode 2 configured as described above, since the electrode portion in contact with the skin is configured by the organic conductive polymer layer 20, the affinity with the skin or the like is higher than that of the metal electrode. Therefore, for the biomedical electrode 2 according to the present invention, when measuring an electrocardiogram or the like, it is not necessary to apply a jelly-like electrolyte to the skin, so that the electrocardiogram or the like can be measured quickly.

例えば、従来の金属電極をゼリー状の電解質を塗布せずに使用した場合、従来の金属電極をゼリー状の電解質を塗布して使用した場合、および本形態の生体用電極２をゼリー状の電解質を塗布せずに使用した場合の筋電図の計測結果をそれぞれ図２（Ａ）、（Ｂ）、（Ｃ）に示すように、本形態の生体用電極２は、ゼリー状の電解質を塗布せずに使用した場合でも、従来の金属電極をゼリー状の電解質を塗布して使用した場合と同様、ノイズレベルが極めて低い。それ故、本発明に係る生体用電極２によれば、心電図などを計測した後、金属電極および肌からゼリー状の電解質を拭き取る必要がないので、手間がかからない。しかも、心電図などを計測した後、単にアルコールで清掃すれば、何回も使用することができ、経済的である。   For example, when a conventional metal electrode is used without applying a jelly-like electrolyte, when a conventional metal electrode is used by applying a jelly-like electrolyte, and when the biological electrode 2 of this embodiment is used as a jelly-like electrolyte As shown in FIGS. 2A, 2B, and 2C, the electromyogram measurement results when used without being applied to the living body electrode 2 are applied with a jelly-like electrolyte. Even when it is used without using it, the noise level is extremely low as in the case where a conventional metal electrode is used by applying a jelly-like electrolyte. Therefore, according to the biomedical electrode 2 according to the present invention, it is not necessary to wipe off the jelly-like electrolyte from the metal electrode and the skin after measuring an electrocardiogram or the like. Moreover, after measuring an electrocardiogram or the like, if it is simply cleaned with alcohol, it can be used many times and is economical.

また、ゼリー状の電解質を長期保管した場合に発生する変質や衛生面での問題を解消できる。さらに、ゼリー状の電解質や金属電極を用いないので、ゼリー状の電解質や金属電極が肌に合わない人についても安心して心電図などを計測することができる。   In addition, it is possible to eliminate deterioration and hygiene problems that occur when a jelly-like electrolyte is stored for a long period of time. Furthermore, since no jelly-like electrolyte or metal electrode is used, an electrocardiogram or the like can be measured with peace of mind even for a person whose jelly-like electrolyte or metal electrode does not fit the skin.

FIG. 3 is an explanatory diagram of the biological electrode according to Embodiment 2 of the present invention.

図３において、本形態の生体用電極アセンブリ１も、心電図、筋電図、眼電図、脳波などの生体信号を測定するためのものであり、ディスク型の生体用電極２およびリード線３を備えている。   In FIG. 3, the biological electrode assembly 1 of this embodiment is also for measuring biological signals such as an electrocardiogram, electromyogram, electrooculogram, and electroencephalogram. The disk-type biological electrode 2 and the lead wire 3 are connected to each other. I have.

ここで、リード線３は、複数本の金属線３１が束ねられたものであり、本形態では、このリード線３の先端部分において金属線３１を広げて電極部分２４を構成し、この電極部分２４を、スルホン酸などのドーパントをドープした有機導電性ポリマー層２０で被覆してある。さらに、有機導電性ポリマー層２０の表面は、必要に応じて樹脂層（図示せず）で被覆してある。   Here, the lead wire 3 is formed by bundling a plurality of metal wires 31, and in this embodiment, the metal wire 31 is spread at the tip portion of the lead wire 3 to form an electrode portion 24, and this electrode portion. 24 is covered with an organic conductive polymer layer 20 doped with a dopant such as sulfonic acid. Furthermore, the surface of the organic conductive polymer layer 20 is covered with a resin layer (not shown) as necessary.

このように構成した生体用電極２でも、肌と接する電極部分が有機導電性ポリマー層２０によって構成されているので、金属電極と比較して肌などとの親和性が高い。従って、本発明に係る生体用電極２については、心電図などを計測する際、肌にゼリー状の電解質を塗布する必要がないので、心電図などを迅速に計測できる。   Even in the biological electrode 2 configured as described above, since the electrode portion in contact with the skin is configured by the organic conductive polymer layer 20, the affinity with the skin or the like is higher than that of the metal electrode. Therefore, for the biomedical electrode 2 according to the present invention, when measuring an electrocardiogram or the like, it is not necessary to apply a jelly-like electrolyte to the skin, so that the electrocardiogram or the like can be measured quickly.

また、本形態では、リード線３の先端部を電極部分として利用しているため、製造工程を簡素化できるので、生体用電極アセンブリ１を安価に製造できる。それ故、医療施設において心電図を形成するときに使用する生体用電極アセンブリ１の他、家庭などで用いる心電計の生体用電極アセンブリ１に適している。   Further, in this embodiment, since the tip end portion of the lead wire 3 is used as an electrode portion, the manufacturing process can be simplified, so that the biological electrode assembly 1 can be manufactured at low cost. Therefore, in addition to the biomedical electrode assembly 1 used when forming an electrocardiogram in a medical facility, it is suitable for the electrocardiographic biomedical electrode assembly 1 used at home and the like.

［実施の形態３］
図４は、本発明の実施の形態３に係る生体用電極の説明図である。 [Embodiment 3]
FIG. 4 is an explanatory diagram of a biological electrode according to Embodiment 3 of the present invention.

図４において、本形態の生体用電極アセンブリ１も、心電図、筋電図、眼電図、脳波などの生体信号を測定するためのものであり、ディスク型の生体用電極２およびリード線３を備えている。ここで、生体用電極２のうち、肌と接触する部分は、ドーパントをドープした有機導電性ポリマー層２０で構成してある。   4, the biological electrode assembly 1 of this embodiment is also for measuring biological signals such as an electrocardiogram, an electromyogram, an electrooculogram, an electroencephalogram, and the like. I have. Here, the part which contacts the skin among the biological electrodes 2 is composed of an organic conductive polymer layer 20 doped with a dopant.

また、本形態の生体用電極アセンブリ１では、生体用電極２とリード線３とがコネクタを介して着脱可能になっている。例えば、生体用電極２に端子孔２５を形成し、リード線３にピン端子３６を構成してある。このため、本形態の生体用電極アセンブリ１では、生体用電極２のみを交換できるという利点がある。   Moreover, in the biological electrode assembly 1 of this embodiment, the biological electrode 2 and the lead wire 3 are detachable via a connector. For example, the terminal hole 25 is formed in the biological electrode 2, and the pin terminal 36 is configured in the lead wire 3. For this reason, the biological electrode assembly 1 of this embodiment has an advantage that only the biological electrode 2 can be replaced.

［実施の形態４］
上記の実施の形態１〜３では、生体用電極２のうち、肌と接触する部分を、ドーパントをドープした有機導電性ポリマー層２０で構成したが、本形態では、この有機導電性ポリマー層２０に、数重量％〜数十重量％のＮｂ（ニオブ）、あるいはＮｂＯ（一酸化ニオブ）からなる導電性粉体をフィラーとして添加してある。このため、本形態では、有機導電性ポリマー層２０の電気的抵抗を低減することができる。また、ＮｂおよびＮｂＯは、金属の中では最も生体との親和性が高いので、肌などとの親和性が高く、接触抵抗の低減を図ることができる。さらに、Ｎｂ、ＮｂＯは、人体に全く毒性が無く、金属アレルギーは全く起こさないという利点がある。 [Embodiment 4]
In said Embodiment 1-3, although the part which contacts the skin among the biological electrodes 2 was comprised with the organic conductive polymer layer 20 which doped the dopant, in this form, this organic conductive polymer layer 20 is comprised. In addition, conductive powder composed of several weight% to several tens weight% of Nb (niobium) or NbO (niobium monoxide) is added as a filler. For this reason, in this embodiment, the electrical resistance of the organic conductive polymer layer 20 can be reduced. Moreover, since Nb and NbO have the highest affinity with living bodies among metals, they have high affinity with skin and the like, and can reduce contact resistance. Furthermore, Nb and NbO have the advantage that there is no toxicity to the human body and no metal allergy occurs.

［他の実施の形態］
なお、実施の形態４では、導電性粉体として、ＮｂまたはＮｂＯを添加したが、Ａｇ、Ｃｕ、Ｔｉやそれらの酸化物を導電性粉体として添加し、有機導電性ポリマー層２０の電気的抵抗を低減してもよい。また、ノイズを低減することを目的に、有機導電性ポリマー層２０に対してトルマリン粉体を添加してもよい。 [Other embodiments]

However, Ag, Cu, Ti, or an oxide thereof is added as the conductive powder, and the electrical conductivity of the organic conductive polymer layer 20 is increased. Resistance may be reduced. Further, tourmaline powder may be added to the organic conductive polymer layer 20 for the purpose of reducing noise.
