【発明の詳細な説明】
従来、生体電位を検出するため、生木と電極との媒介体
として種々の導電性デルが考案されてきた。しかし、粘
着力の不足、更にはデルの；疑集力が小さいため、充分
な性能を具備するものにはなり得なかった。DETAILED DESCRIPTION OF THE INVENTION Conventionally, various conductive dels have been devised as mediators between live wood and electrodes in order to detect biopotential. However, due to the lack of adhesion and the weak convergence of Dell, it was not possible to achieve sufficient performance.
これを解決するために、ポリアクリル酸及び／又はポリ
アクリル酸塩を多官能エポキシ化合物で架橋させた電極
デルパッドが提案されているが、これにおいても粘着力
が弱い、充分なデル強度が得られない等の欠点があり、
長時間にわたって身体と電極とを堅固に接着することは
非常に困難なことである。また、この材料から成るデル
は、多価金属イオンの存在で容易にデル化するという性
質を有するため、身体から分泌される微量の多価金属イ
オンによってデル化し、粘着力の低下は避けられないも
のである。To solve this problem, an electrode del pad made by crosslinking polyacrylic acid and/or polyacrylate with a polyfunctional epoxy compound has been proposed, but even this has weak adhesive force and sufficient del strength cannot be obtained. There are drawbacks such as not having
It is extremely difficult to firmly adhere the electrode to the body for a long period of time. In addition, the adhesive made of this material has the property of easily forming into an adhesive in the presence of polyvalent metal ions, so a trace amount of polyvalent metal ions secreted from the body will cause the adhesive to deteriorate, resulting in an unavoidable decrease in adhesive strength. It is something.
更に、この材料からなるデルを低周波治療器用に用いた
場合に至っては、このデルが加水分解され易いという性
質を有するため、低周波治療器が比較的大きな電流を生
体に供給することから、電極に接するデルの凝集力が著
しく低下し、ゲルの着脱に支障を来すことは大いに予想
され得ることである。Furthermore, when a del made of this material is used for a low-frequency treatment device, since this del has the property of being easily hydrolyzed, the low-frequency treatment device supplies a relatively large current to the living body. It can be expected that the cohesive force of the gel in contact with the electrode will be significantly reduced, causing problems in attaching and detaching the gel.
前述の欠点を克服するため検討を重ねた結果、考案者ら
は、マレイン酸を分子中に有するポリマーが優れた性質
を有することを見出した。As a result of repeated studies to overcome the above-mentioned drawbacks, the inventors discovered that a polymer having maleic acid in its molecule has excellent properties.
マレイン酸は１分子中にカルボン酸を二つ有するもので
あるため、一方のカルボキシル基の誘起効果によって、
もう一方のカルボキシル基の酸性を高めることが知られ
ている。このことは、次に示すアクリル酸、マレイン酸
の解離定数を比較することによっても実証されるもので
ある。Maleic acid has two carboxylic acids in one molecule, so due to the inducing effect of one carboxyl group,
It is known to increase the acidity of the other carboxyl group. This is also demonstrated by comparing the dissociation constants of acrylic acid and maleic acid shown below.
従って、分子中にマレイン酸を有するポリマーの方が、
アクリル酸を含むものに比べより強い酸性であり、この
性質により、これらポリマーを多官能エポキシで架橋し
た場合、アクリル酸から成るポリマーに比べ、マレイン
酸から成るポリマーのゲルの凝集力は著しく増大すると

有するポリマーを用いた方が、架橋剤として加える多官
能エポキシ化合物が少量で充分な凝集力を有することを
意味し、これによって、マレイン酸から成るポリマーを
用いたゲルの方が粘着力も大きくなるという優位性をら

ボン酸によって発現するものであり、架橋剤を多く使用
することにより、この解離性カルボン酸が消費されてし
まうからである。また、架橋剤が多く添加された場合、
デルの物性は弾性を増し、流動性が乏しくなり、このこ
とが粘着力の低下を招くことが知られており、このこと
からも、少量の多官能エポキシで充分なゲル強度を有す
るマレイン酸から成るポリマーの方が優れていることは
明確である。更に、マレイン酸から成るポリマーの場合
、中和度を適切にコントロールすることｌこより、モノ
カルボン酸陰イオンが分子内で水素結合が可能であると
いうことからも、アクリル酸から成るポリマーにはない
優れた性質を有している。Therefore, polymers with maleic acid in the molecule are more
They are more acidic than those containing acrylic acid, and due to this property, when these polymers are crosslinked with a multifunctional epoxy, the cohesive strength of the gel of a polymer made of maleic acid increases significantly compared to that of a polymer made of acrylic acid. It has the advantage of This means that when using a polymer containing maleic acid in the molecule, a small amount of the polyfunctional epoxy compound added as a crosslinking agent has sufficient cohesive strength. The advantage of this gel is that it has greater adhesive strength. This is because adhesiveness is caused by dissociated carboxylic acid, and if a large amount of crosslinking agent is used, this dissociable carboxylic acid is consumed. In addition, when a large amount of crosslinking agent is added,
It is known that the physical properties of gel increase elasticity and poor fluidity, which leads to a decrease in adhesive strength.For this reason, maleic acid, which has sufficient gel strength with a small amount of polyfunctional epoxy, It is clear that the polymer consisting of Furthermore, in the case of polymers made of maleic acid, it is necessary to appropriately control the degree of neutralization, and because monocarboxylic acid anions can form hydrogen bonds within the molecule, polymers made of acrylic acid do not have this ability. It has excellent properties.
また、マレイン酸から成るポリマーを用いた導電性粘着
デルは、アクリル酸から成るポリマーを使用したデルと
異なり、多価金属イオンの存在によってゲル化しないと
いう特徴をもつため、長時間にわたって身体と電極とを
安定して接続することが可能となった。In addition, conductive adhesive gel made of a polymer made of maleic acid, unlike gel made of a polymer made of acrylic acid, has the characteristic that it does not gel due to the presence of polyvalent metal ions, so it can stay connected to the body and electrode for a long time. It is now possible to stably connect with.
このマレイン酸から成るポリマーを用いたデルを、低周
波治療器等の比較的大きな電流を装置から身体へ供給す
る目的に使用した場合においても、このゲルは加水分解
され難いという性質を有するため、長時間の使用におい
ても安定した物性値を有するものであり、電極からの着
脱も容易であった。Even when a gel using a polymer made of maleic acid is used for the purpose of supplying a relatively large current to the body from a device such as a low frequency treatment device, this gel has the property of being difficult to be hydrolyzed. It had stable physical properties even after long-term use, and was easy to attach and detach from the electrode.
