【考案が解決しようとする課題】[Problems to be solved by the device]

上記のように構成された従来のクリップにおいて、電極8は金属板で形成され ているため、四肢に装着時に心電図用クリームを塗布する必要があった。このた め測定後の洗滌に手間がかかるという問題があった。この手間を省くためクリー ムの代りに生理的食塩水などの電解質溶液を塗布すると、電極8が腐食するおそ れがあった。 In the conventional clip configured as described above, since the electrode 8 is formed of a metal plate, it is necessary to apply the ECG cream to the extremities when the clip is attached. Therefore, there is a problem in that cleaning after the measurement takes time. If an electrolyte solution such as physiological saline is applied instead of cream in order to save this trouble, the electrode 8 may be corroded.

【0004】 また電極8が一方の挟持部7に固定されているため、被検者の四肢の太さなど の相異により電極8が四肢に確実に接触せず、複数種類のクリップを用意しなけ ればならなかった。Further, since the electrode 8 is fixed to the one holding portion 7, the electrode 8 does not surely come into contact with the extremities due to differences in the thickness of the extremities of the subject, and a plurality of types of clips are prepared. I had to do it.

【0005】 本考案は、上記事情に鑑みてなされたもので、電極の電解質溶液による腐食の 発生を防ぎ、被検者の体型にかかわりなく最適な密着性を得ることのできる四肢 電極用クリップを提供することを目的とする。The present invention has been made in view of the above circumstances, and provides a limb electrode clip that can prevent corrosion of an electrode due to an electrolyte solution and can obtain optimum adhesion regardless of the body shape of a subject. The purpose is to provide.

【実施例】【Example】

以下、本考案の四肢電極用クリップの一実施例を図面を参照して説明する。 An embodiment of the clip for extremity electrodes of the present invention will be described below with reference to the drawings.

【0011】 図1及び図2に本考案の一実施例の構成を示す。図1,2において、図6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。本実施例の特徴は電極としての電極端子11を導電ゴムでほぼU字状に 形成し、クリップの挟持部7に弾性的に嵌合装着し、電極端子11の四肢に対向 する面に格子状の凹溝12を形成した点にある。電極端子11の一端には誘導コ ード9の図示しない先端チップを差し込む差込み孔13が形成されている。1 and 2 show the configuration of an embodiment of the present invention. 1 and 2, parts corresponding to those of the conventional example shown in FIG. 6 are denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The feature of this embodiment is that the electrode terminal 11 as an electrode is formed of conductive rubber into a substantially U-shape, and is elastically fitted and attached to the holding portion 7 of the clip. The groove 12 is formed. An insertion hole 13 is formed at one end of the electrode terminal 11 to insert a tip (not shown) of the induction code 9 into the insertion hole 13.

【0012】 本実施例によれば、電解質溶液に腐食されない導電ゴムで構成された電極端子 11の表面に格子状の凹溝12が形成されており、凹溝12により生理的食塩水 などの電解質溶液を保持することができるので、従来必要であった心電図用クリ ームを塗布する必要がなくなる。この結果、測定後の電極端子11の洗滌は食塩 水を洗い流すだけでよく、洗滌が簡単となる。また電極端子11は弾性的にクリ ップの挟持部7に嵌合されており、摩擦力で位置決め保持されているので、電極 端子11を挟持部7に沿って移動することができる。従って被検者の四肢の太さ に応じて移動することにより、最適の密着性が得られる。According to this embodiment, the grid-shaped concave grooves 12 are formed on the surface of the electrode terminal 11 made of conductive rubber that is not corroded by the electrolyte solution, and the concave grooves 12 form an electrolyte such as physiological saline. Since the solution can be retained, it is not necessary to apply the electrocardiographic cream, which was necessary in the past. As a result, the electrode terminal 11 can be washed after the measurement by washing away the saline solution, and the washing can be simplified. Further, since the electrode terminal 11 is elastically fitted to the gripping portion 7 of the clip and is positioned and held by the frictional force, the electrode terminal 11 can be moved along the gripping portion 7. Therefore, by moving according to the thickness of the subject's extremities, optimum adhesion can be obtained.

【0013】 上記実施例では電極端子11を摩擦力でクリップの挟持部7に保持する場合に ついて説明したが、図3に示すように電極端子11に突起部14を設け、クリッ プの挟持部7に突起部14が嵌合する複数の孔部15を形成して、被検者の体型 に応じて最適な孔部15に突起部14を嵌合させてもよい。このようにして電極 端子11を挟持部7に位置決め固定することにより、電極端子11の四肢に対す る最適の密着性が得られる。In the above embodiment, the case where the electrode terminal 11 is held by the clip holding portion 7 by the frictional force has been described. However, as shown in FIG. 3, the electrode terminal 11 is provided with the protrusion 14 and the clip holding portion is provided. It is also possible to form a plurality of holes 15 into which the protrusions 14 fit and to fit the protrusions 14 into the optimum holes 15 according to the body shape of the subject. By positioning and fixing the electrode terminal 11 to the sandwiching portion 7 in this manner, optimum adhesion of the electrode terminal 11 to the extremities can be obtained.

【0014】 図4及び図5に本考案の他の実施例の構成を示す。本実施例では電極端子11 の対向する肉厚の両端部にそれぞれスリット孔16を貫通して形成し、図6に示 す従来例における金属電極8の対向する二辺に形成された突起部8aをスリット 孔16に嵌合して、金属電極8に電極端子11を保持固定した。4 and 5 show the configuration of another embodiment of the present invention. In this embodiment, the slit holes 16 are formed at both ends of the electrode terminal 11 facing each other in the thickness thereof, and the protrusions 8a formed on the two opposite sides of the metal electrode 8 in the conventional example shown in FIG. Was fitted into the slit hole 16 to hold and fix the electrode terminal 11 on the metal electrode 8.

【0015】 本実施例によれば、従来の金属電極8が装着されたクリップを用い、金属電極 8を表面に格子状の凹溝12が形成され導電ゴムで構成された電極端子11を被 着することにより、従来必要であった心電図用クリームを不要とし、生理的食塩 水などの電解質溶液を保水させることができ、洗滌を容易にすることができる。According to the present embodiment, the conventional clip having the metal electrode 8 mounted thereon is used to cover the metal electrode 8 and the electrode terminals 11 made of conductive rubber having the grid-shaped grooves 12 formed on the surface thereof. By doing so, it is possible to eliminate the need for an electrocardiographic cream, which has been conventionally required, to retain an electrolyte solution such as physiological saline, and to facilitate washing.

【考案の効果】[Effect of device]

以上説明したように、本考案の四肢電極用クリップによれば、クリップの挟持 部に表面に凹溝が形成され導電ゴムで構成された電極を装着するようにしたので 、電極が腐食されることなく生理的食塩水などの電解質溶液を保水させることが でき、洗滌を容易にすることができる。また電極を移動することにより、被検者 の体型に応じて電極の四肢に対する最適の密着性を得ることができる。 As described above, according to the limb electrode clip of the present invention, since the electrode formed of the conductive rubber having the concave groove formed on the surface of the clip is mounted, the electrode is corroded. Instead, an electrolyte solution such as physiological saline can be kept in water and cleaning can be facilitated. Further, by moving the electrode, it is possible to obtain the optimum adhesion of the electrode to the extremities according to the body shape of the subject.

【0017】 また金属電極に上記電極を装着することにより、金属電極が装着された従来の クリップを用いても、腐食を発生させることなく電解質溶液を保水させることが でき、洗滌を容易にすることができる。Further, by mounting the above electrode on the metal electrode, the electrolyte solution can be retained in water without causing corrosion even if the conventional clip on which the metal electrode is mounted is used, and the cleaning is facilitated. You can
