た生体用電極の製造方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a biological electrode, and more specifically, the surface of a plastic substrate molded into the shape of a biological electrode is coated with silver-silver chloride (Ag-hgO). The present invention relates to a method of manufacturing a biological electrode.

定性等の点で優れているからである。As biological electrodes, those made of Ag-A meso are widely used. This is because they are excellent in terms of static electrode potential, polarization voltage, stability, etc.

量であシ安価であるから、いわゆる使い捨て電極として
きわめて有用である。However, a biomedical electrode made entirely of Ag-AgC is heavy and expensive. For this reason, recently, biomedical electrodes have been used in which the surface of a base material such as plastic molded into the shape of a biomedical electrode is coated with Ag-Ago. Although such biological electrodes lack durability, they are lightweight and inexpensive, so they are extremely useful as so-called disposable electrodes.
一般にプラスチ、り基体表面を金属で被覆する方法とし
て、真空蒸着法、スパッタリング法等があるがこれらは
設備、費用の点で問題がある。そこで現在生体用電極の
製造には主に、次の２つの方法が用いられている。Generally, there are vacuum evaporation methods, sputtering methods, etc. as methods for coating the surface of plastic substrates with metals, but these methods have problems in terms of equipment and costs. Therefore, the following two methods are currently used to manufacture biological electrodes.
第１は、生体用電極の形に成型されたプラスチ、り基体
の表面に銀ペースト（銀塗料）を塗布する方法である。The first method is to apply silver paste (silver paint) to the surface of a plastic substrate molded into the shape of a biological electrode.
第２は、生体用電極の形に成型されたプラスチック基体

埋めるようにＮｉ、Ｃｕ等を付着させて（溶液メッキで

する方法である。Second, the surface of a plastic substrate molded into the shape of a biological electrode is made uneven by chemical etching, etc., and Ni, Cu, etc. are attached to fill the indentations (reinforced by solution plating), and a base layer is formed. This method involves making a substrate and electroplating Ag on top of this substrate.
上記第１の方法は、銀粉を混入した塗料を使うためコス

された電極は、被覆材であるＡｇにピンホールがあると
、下地のＣｕ。The first method described above has the disadvantage of being expensive because it uses a paint containing silver powder. On the other hand, the second method above is
Although it is economically superior, since different metals come into contact with each other, it lacks electrical and chemical stability, which causes noise to be mixed into biological signals such as electrocardiograms. Further, in the electrode manufactured by this second method, if there is a pinhole in the Ag coating material, the Cu underlying layer will be removed.
Ｎｉが表出するためその部分から酸化が進みいわゆる静
止電極電位が不安定となる。特にＣｕが酸化される（緑

本発明は上記欠点に鑑みなされたものでその目的は、す

極を製造する方法を提供することである。The present invention was made in view of the above-mentioned drawbacks, and its purpose is to produce a lightweight and inexpensive biomedical electrode that has electrochemical properties similar to biomedical electrodes made entirely of Ag-Ag (M). The goal is to provide a method to do so.
そこで本発明では、生体用電極の形状に成型されたプラ

て生体用電極を製造した。Therefore, in the present invention, a plastic substrate molded into the shape of a biological electrode is immersed in an ammoniacal silver nitrate solution, and a reducing organic substance is added to this solution to adhere silver to the surface of the plastic substrate. A biological electrode was manufactured by electrolyzing the Mail solution using the plastic substrate with silver adhered to its surface as an anode to make the surface of the plastic substrate Ag-Ago.
本発明の方法は２つの過程から成り立っている。The method of the invention consists of two steps.
まず第１の過程は、いわゆる鋼装反応を利用して、あら
かじめ生体用電極の形に成型されているプラスチック基
体の表面をＡｇで神覆するものである。In the first step, the surface of a plastic substrate, which has been previously formed into the shape of a biological electrode, is coated with Ag using a so-called steel-cladding reaction.
まず硝酸銀溶液にアンモニア水を注入し、当初できる沈
殿物Ａｇ２Ｏが完全に溶解する寸で加える。First, aqueous ammonia is poured into the silver nitrate solution until the Ag2O precipitate that is initially formed is completely dissolved.
このときの溶液がアンモニア性硝酸銀溶液である。The solution at this time is an ammoniacal silver nitrate solution.
次に、あらかじめ生体用電極の形に成型しである清浄な
プラスチック基体を、前記のアンモニア性硝酸銀溶液と
ホルマリン等の還元性有機物（以下単に還元剤という）

面にＡｇが析出する。Next, a clean plastic substrate, which has been previously molded into the shape of a biological electrode, is mixed with the ammoniacal silver nitrate solution and a reducing organic substance such as formalin (hereinafter simply referred to as a reducing agent).
Soak in a mixture of In this way, Ag is deposited on the surface of the plastic substrate.
ここでアンモニア性硝酸銀溶液の濃度は、０．３ｍｊｉ

ｇが付着する効率が悪くなり、多ければプラスチ、り基
体表面に付着するＡｇはむらを生じる。Here, the concentration of the ammoniacal silver nitrate solution is 0.3 mji
A range of /l to 8moV1 is preferable. If this concentration is low, the reaction rate will be low and it will take a long time to deposit the required amount of Ag on the surface of the plastic substrate. Also, if this concentration is high, for example close to the solubility limit, the Ag deposited on the surface of the plastic substrate will become uneven. Similarly, if there is less reducing agent 5, A
The efficiency with which Ag adheres becomes poor, and if too much Ag adheres to the surface of the plastic substrate, the Ag adheres to the surface of the substrate becomes uneven.
第２の過程は上記のようにして表面にＡｇを付着された
プラスチック基体をＨＢＯ＃溶液に浸漬し、これを陽極
としてＮａＣｊノ ！液を電気分解しプラスチック基体
表面をＡｇ −Ａｇ ０１とするものである。In the second step, the plastic substrate with Ag adhered to its surface as described above is immersed in an HBO# solution, and this is used as an anode to generate NaCjNO! The liquid is electrolyzed to make the surface of the plastic substrate Ag-Ag 01.
このとき陰極にはｐｔ板を用いる。At this time, a PT plate is used as the cathode.
ここで例えばＮａｏ４′溶液の濃度が０．９俤であると
き、電流密度は０．１ｍＶｃＪ〜６．５ｍＡ／ｃｒｙと
し、通電時間は６０分〜３分とすれば良好である。For example, when the concentration of the Nao4' solution is 0.9, it is preferable to set the current density to 0.1 mVcJ to 6.5 mA/cry and to set the current application time to 60 minutes to 3 minutes.

用電極として十分使用可能である。Although plating is possible regardless of the material of the plastic substrate, there are some that cannot be used as biological electrodes because the Ag tends to peel off easily. Natural ABS resin, glass fiber-containing ABS resin, etc. have good adhesion and can be used as biological electrodes.

簡略化されるので製造が簡単でかつ経済的である。According to the present invention, since the Ag directly attached to the surface of the plastic substrate can be made into Ag-Agcz, it is possible to produce a single electrode for biological use with excellent electrochemical properties. Further, according to such a method, the manufacturing process is simpler and more economical than the conventional method which requires pre-treatment of the chemically etched pipe because the process is simplified.

面はＡｇ−Ａｇ０＃となる。Example 1 A silver nitrate solution was prepared by adding 5 g of silver nitrate to 25 cc of pure water and completely dissolving it. When 10 g of aqueous ammonia is gradually dripped into this silver nitrate solution, the solution initially turns brown. Furthermore, 10 thiammonia water is instilled, and the infusion is stopped when the solution becomes clear. This solution is an ammoniacal silver nitrate solution. Next, natural ABS molded into the shape of the electrode
After the resin is immersed in formalin, it is immersed in the ammoniacal silver nitrate solution described above. 5 minutes after immersion, add Q, 5CC1'' of formalin. At this time, plastic (
(Natural ABS resin) Ag is deposited on the substrate surface. After 7 minutes of immersion in the ammoniacal silver nitrate solution, the plastic substrate is removed, washed with water, and dried. Next, this plastic substrate with Ag adhered to its surface is immersed in a 0.9 inch NaOΔ solution, and the NaO solution is electrolyzed using this as an anode. At this time, the cathode is a PT plate. Then, when 5 degrees of direct current is passed for about 3 minutes, the surface of the plastic substrate becomes Ag-Ag0#.

Further, when handling the biomedical electrode manufactured in this manner, no problems such as peeling of Ag-AgGJ on the surface of the plastic substrate occurred.

Aqueous ammonia No. 28 was gradually dripped into this silver nitrate solution, and as in Example 1, when the solution became transparent, the dripping was stopped to prepare an ammoniacal silver nitrate solution. Next, the glass fiber-containing ABS resin molded into the shape of an electrode was placed in an ammoniacal silver nitrate solution, and 2cc of acetone was added.
Pour in and soak for 1 hour. At this time, Ag is deposited on the surface of the plastic (glass fiber-containing, 9ABS resin) substrate. The plastic substrate is then removed from the solution, washed with water, and then dried. Next, this plastic substrate with hi adhered to the surface is immersed in a 0.9-inch NaCl solution, and this is used as an anode to electrolyze the Na(17 solution). At this time, a PT plate is used as the cathode. When a DC current of 0.511'LA is applied for 30 minutes, the substrate surface becomes Ag-A.
It becomes g01.
