Description

【0001】
【発明の属する技術分野】
本発明は、生体に装着された電極が検出する生体信号を計測装置に誘導する生体電気誘導コードに関し、特に生体に負担をかけることがなく、かつ複数個の電極が検出する生体信号を正確に誘導することのできる生体電気誘導コードに関する。
【0002】
【従来の技術】
生体の複数箇所に装着された電極が検出する生体信号を1個の計測装置に誘導する誘導コードとしては、従来から種々のものが用いられている。図4に従来の生体電気誘導コードの一例の構成を示す。図4において、先端にそれぞれ電極1が接続された複数本、例えば10本の電極リード線2の基端は分岐部3に導入されている。10本の電極リード線2は分岐部3内において1本に集束され、分岐部3に接続された接続コード4を介して図示しない計測装置に導出される。
【0003】
分岐部3は硬質プラスチックなどで六角形の偏平箱状に形成されており、10本の電極リード線2のうち6本は分岐部3の一辺に接続され、他の4本はこの一辺の両側に隣接する二辺にそれぞれ2本ずつ接続されている。そして一辺に接続された6本は胸部電極リード線、他の4本は四肢電極リード線となっている。
【0004】
【発明が解決しようとする課題】
上記のように構成された生体電気誘導コードを用いて生体信号を測定する場合、分岐部3を生体の表面の所定の位置に接着テープなどを用いて装着固定し、電極リード線2の先端に接続された10個の電極1を生体の胸部及び四肢の測定部位に装着する。このとき従来の分岐部3の生体装着面はほぼ平面となっているため、分岐部3が生体面に対して滑りやすく、検出した生体信号にノイズが発生するおそれがあった。また、分岐部3が生体の皮膚表面に密着するため、皮膚がムレて炎症を起こしやすい欠点もあった。
【0005】
一方、胸部電極リード線と四肢電極リード線の分岐部3への導入部が近接しているため、分岐部3を生体表面に装着固定するテープは、これらの電極リード線2に干渉しない中心から外れた位置に接着しなければならず、分岐部3を強固に固定することができなかった。
【0006】
本発明はこのような状況に鑑みてなされたもので、分岐部を生体表面に装着するときに滑りやムレなどが発生することがなく、安定した生体信号の検出を行うことができる生体電気誘導コードを提供することを目的とする。
【0007】
【課題を解決するための手段】
上記目的を達成するために、請求項1に記載の本発明は、一端にそれぞれ生体信号を検出する電極が接続される複数本の電極リード線と、一端が生体電気計測装置に接続される少くとも1本の接続コードと、前記電極リード線のそれぞれの他端と前記接続コードの他端とを電気的・物理的に中継する分岐部とを有し、前記分岐部は、接着テープにより生体の皮膚表面に装着される生体電気誘導コードにおいて、前記分岐部の生体装着面に複数個の凸部を散在して設けたことを特徴とする。
【0008】
請求項1に記載の本発明においては、分岐部の生体装着面に複数個の凸部を設けたので、分岐部を生体表面に装着するとき、凸部が生体表面に食い込み、分岐部が生体表面に対して滑りにくくなる。また凸部により分岐部が生体装着面と生体表面との間に間隙が生じ、ムレが発生することを防止できる。
【0009】
【発明の実施の形態】
以下、本発明の生体電気誘導コードの実施の形態を図面を参照して説明する。図1は本発明の生体電気誘導コードの実施の形態の構成例を示す下面図、図2は図1の上面図、図3は図1の分岐部の側面図である。これらの図において、図4に示す従来例の部分と対応する部分には同一の符号を付してあり、その説明は適宜省略する。
【0010】
図1乃至図3において、分岐部3はプラスチックでほぼ扇形の偏平箱状に形成されており、図中上辺の円弧部分には6本の胸部電極リード線2aの基端側が導入されている。分岐部3の両側部にはそれぞれ2本の四肢電極リード線2bの基端側が導入されており、胸部電極リード線2aと四肢電極リード線2bとは分岐部3の外周から異なる方向に突出している。両電極リード線2a、2bは分岐部3内において集束され、分岐部3の扇形の中心部から外側に突出する接続コード4に接続されている。また各電極リード線2a、2bの先端にはそれぞれ生体信号を検出する電極1a、1bが接続されている。さらに分岐部3の生体装着面には複数個の円形の凸部5が一体に形成されている。また、接続コード4の他端は生体電気計測装置、例えば心電計6に接続されている。
【0011】
生体信号を検出するときは分岐部3を接着テープ7を用いて生体の皮膚表面の所定の位置に装着固定する。このとき図2に示すように、接着テープ7は分岐部3のほぼ中心の部分に接着され、胸部電極リード線2aと四肢電極リード線2bとの間において外側に引き出される。次に胸部電極リード線2aの先端に接続された電極1aを胸部の測定部位に、四肢電極リード線2bの先端に接続された電極2bを四肢の測定部位にそれぞれ装着し、生体信号の検出を行う。各電極2a、2bが検出した生体信号は接続コード4を介して心電計6に導出される。
【0012】
本実施の形態によれば、分岐部3の生体装着面に複数の凸部5が設けられているので、分岐部3を接着テープ7により生体表面に装着したとき、凸部5が皮膚に食い込み、分岐部3が生体表面に対して滑ることを係止することができる。この結果、測定された生体信号にノイズが発生することがなくなり、正確な測定を行うことができる。また凸部5により分岐部3の生体装着面と生体表面との間に間隙が生じるので、皮膚表面がムレることを防止できる。
【0013】
また、胸部電極リード線2aと四肢電極リード線2bとを分岐部3の外周から異なる方向に分離して突出させているので、分岐部3を接着テープ7により生体表面に装着するとき、接着テープ7を各電極リード線2a、2bに干渉されることなく分岐部3のほぼ中心に接着することができ、分岐部3を生体表面に強固に装着固定することができる。
【0014】
上記実施の形態の構成例では電極リード線2が6本の胸部電極リード線2aと4本の四肢電極リード線2bとから構成されている場合について説明したが、これらの電極リード線2a、2bの本数はそれぞれ6本、4本に限定されないことはいうまでもない。
【0015】
【発明の効果】
以上説明したように、請求項1に記載の生体電気誘導コードによれば、複数本に分岐された電極リード線を集束する分岐部の生体装着面に複数個の凸部を設けたので、分岐部が生体装着面に対してずれて検出した生体信号にノイズが発生したり、皮膚表面にムレが発生することを防止できる。

2. Description of the Related Art Various types of guidance codes have been conventionally used as guidance codes for guiding a biological signal detected by electrodes attached to a plurality of portions of a living body to one measuring device. FIG. 4 shows an example of a configuration of a conventional bioelectric induction cord. In FIG. 4, the base ends of a plurality of, for example, ten electrode lead wires 2 each having an electrode 1 connected to the distal end are introduced into the branch portion 3. The ten electrode lead wires 2 are converged into one in the branch part 3, and are led out to a measuring device (not shown) via the connection cord 4 connected to the branch part 3.
[0003]
The branch portion 3 is formed in a hexagonal flat box shape using a hard plastic or the like. Six of the ten electrode lead wires 2 are connected to one side of the branch portion 3 and the other four are on both sides of this one side. Are connected to two sides adjacent to each other. Six of them connected to one side are chest electrode lead wires, and the other four are limb electrode lead wires.

When measuring a biological signal using the bioelectric induction cord configured as described above, the branch portion 3 is attached and fixed to a predetermined position on the surface of the living body using an adhesive tape or the like, and is attached to the tip of the electrode lead wire 2. The ten connected electrodes 1 are mounted on the measurement site of the chest and limbs of the living body. At this time, since the living body mounting surface of the conventional branch portion 3 is substantially flat, the branch portion 3 is likely to slip on the body surface, and there is a possibility that noise is generated in the detected biological signal. In addition, since the branch portion 3 is in close contact with the skin surface of the living body, there is a disadvantage that the skin is stuffy and easily inflamed.
[0005]
On the other hand, since the introduction portions of the chest electrode lead wire and the limb electrode lead wire into the branch portion 3 are close to each other, the tape for attaching and fixing the branch portion 3 to the surface of the living body is located at a center that does not interfere with these electrode lead wires 2. It has to be adhered to a position where it has come off, and the branch portion 3 cannot be firmly fixed.
[0006]
The present invention has been made in view of such a situation, and a bioelectric induction that can perform stable detection of a biological signal without causing slippage or stuffiness when the branch portion is attached to the surface of a living body. The purpose is to provide the code.
[0007]
[Means for Solving the Problems]
In order to achieve the above object, the present invention according to claim 1 has a plurality of electrode leads each having an end connected to an electrode for detecting a biological signal, and one end connected to a bioelectric measurement device. both have one connection code, the electrical and physical relayed to bifurcation and the other end of each of the other end with the connecting cord of the electrode lead wire, the branch unit, the biological the adhesive tape In the bioelectric induction cord to be mounted on the skin surface, a plurality of projections are scatteredly provided on the body mounting surface of the branch portion.
[0008]
According to the first aspect of the present invention, since a plurality of projections are provided on the living body mounting surface of the bifurcation, when the bifurcation is mounted on the surface of a living body, the projections bite into the surface of the living body, and the bifurcation is a living body. Less slippery to the surface. In addition, it is possible to prevent a gap from being formed between the living body mounting surface and the living body surface at the branch portion due to the convex portion, thereby preventing the occurrence of stuffiness.
