Description
本発明は、被検者の皮膚面に装着して生体電気を検出する生体電極装置に関する。 The present invention relates to a bioelectrode device that is mounted on a skin surface of a subject and detects bioelectricity .
心電図検査は、生体測定用電極を被検者の胸部に装着し、この生体測定用電極により検出される生体電気を、一定期間記録することで行われる。
生体測定用電極として、外乱ノイズの混入を防止するためのシールド構造を持たせ、かつ、装着感を向上させると共に生体電極及び接続構造をコンパクトにするものが提案されている（特許文献１）。
特許文献１における生体電極は、一方から第１の絶縁層、シールド層、第２の絶縁層、電極素子層及び電解質の複数層で構成している。シールド層は、電極素子層を覆うように配設され、重なり合った部分の一部が露出して挟持される挟持部を構成している。
そして、挟持部の一方の面にシールド層が露出し、挟持部の他方の面に電極素子層が露出している。
また、生体測定用電極として、良好な通気性を維持しつつ、電極部の短絡を防止して高精度な測定を行うものが提案されている（特許文献２）。
特許文献２における生体電極は、一対の面を有する膜状の基材と、この基材の一方の面との間に電極部を介在させつつ、基材の一方の面に設けられたゲル層と、基材の他方の面の電極部の対向位置に設けられた、電極部の導電性シールド膜と、このシールド膜を封止する非導電性レジスト膜とを有する。そして、電極部の導電性シールド膜は、基材の他方の面の、電極部の対向位置に配置された銀膜と、銀膜を被覆するカーボン膜とからなる。
本発明者は、クリップによって着脱が容易な生体測定用電極において、電極の短絡を防止するとともにクリップの薄型化も図ることができる生体測定用電極を既に提案している（特許文献３）。
The electrocardiogram test is performed by attaching a biometric electrode to the subject's chest and recording bioelectricity detected by the biometric electrode for a certain period.
As a biometric electrode, there has been proposed an electrode having a shield structure for preventing disturbance noise from being mixed, improving the wearing feeling, and making the bioelectrode and the connection structure compact (Patent Document 1).
The bioelectrode in Patent Document 1 includes a first insulating layer, a shield layer, a second insulating layer, an electrode element layer, and a plurality of electrolyte layers from one side. The shield layer is disposed so as to cover the electrode element layer, and constitutes a sandwiching portion in which a part of the overlapping portion is exposed and sandwiched.
The shield layer is exposed on one surface of the sandwiching portion, and the electrode element layer is exposed on the other surface of the sandwiching portion.
In addition, as an electrode for biometric measurement, one that performs high-accuracy measurement by preventing a short circuit of an electrode portion while maintaining good air permeability has been proposed (Patent Document 2).
The bioelectrode in Patent Document 2 is a gel layer provided on one surface of a substrate while interposing an electrode portion between the film-shaped substrate having a pair of surfaces and one surface of the substrate. And a conductive shield film of the electrode part provided at a position opposite to the electrode part on the other surface of the substrate, and a non-conductive resist film for sealing the shield film. And the conductive shield film of an electrode part consists of the silver film arrange | positioned on the other surface of a base material in the position facing an electrode part, and the carbon film which coat | covers a silver film.
The present inventor has already proposed a biometric electrode that can be easily attached / detached by a clip and that can prevent the electrode from being short-circuited and can be made thinner (Patent Document 3).
特許文献１では、電極層は第２の絶縁層によってシールド層との間は絶縁されているが、電極層端部や電解質側の面が露出しているため、被験者に装着した状態で、被験者の汗や衣類の水分含浸によって電極部が短絡する場合が生じてしまう。
また、特許文献１では、生体測定用電極の挟持部は、一方の面にシールド層を、他方の面に電極素子層を形成しているため、この生体測定用電極を保持する挟持クリップには、上部部分と下部部分にそれぞれシールド端子と電極端子を配置しなければならなくなる。
特許文献２では、特許文献１のような電極の短絡は防止できるが、記録装置への接続はリード線によって行うものである。
特許文献３では、電極の短絡を防止するとともにクリップの薄型化も図ることができる。
In Patent Document 1, the electrode layer is insulated from the shield layer by the second insulating layer, but the end of the electrode layer and the surface on the electrolyte side are exposed. The electrode part may be short-circuited by perspiration or moisture impregnation of clothing.
Further, in Patent Document 1, since the clamping portion of the biometric electrode has a shield layer on one surface and an electrode element layer on the other surface, the clamping clip that holds the biometric electrode is not included in the clamping clip. The shield terminal and the electrode terminal have to be arranged in the upper part and the lower part, respectively.
In Patent Document 2, short-circuiting of electrodes as in Patent Document 1 can be prevented, but connection to a recording apparatus is performed by a lead wire.
In Patent Document 3, it is possible to prevent the electrode from being short-circuited and to reduce the thickness of the clip.
本発明は、クリップによって着脱が容易な生体測定用電極において、電極の短絡を防止するとともにクリップの薄型化も図ることができるとともに、更に生体測定用電極をクリップに保持した状態での電極端子に接続する生体信号線の端部におけるノイズ対策を行うことができる生体電極装置を提供することを目的とする。 The present invention provides a biometric electrode that is easy to attach and detach with a clip, which can prevent the electrode from being short-circuited and can be made thin. Further, the present invention provides an electrode terminal with the biometric electrode held by the clip. An object of the present invention is to provide a bioelectrode device capable of taking measures against noise at the end of a biosignal line to be connected.
