PROBLEM TO BE SOLVED: To make it possible to quickly mount an electrocardiograph electrode device while accurately performing positioning of an electrode without imposing an excessive burden on a subject.SOLUTION: An electrocardiograph electrode device 1A including a plurality of chest electrodes 10a, 10b, 10c arranged, on the inner surface of an electrode holder 50 composed of a belt-like member, in the longer direction performs measurement with the respective electrodes 10a, 10b, 10c mounted laterally on the chest of a subject so that the respective electrodes are in contact with skins at measurement positions. To both end sides of the belt-like member are attached locking bodies 51a, 51b having a predetermined shape. The locking bodies 51a, 51b are passed through both armpits of the subject lying on his/her back and are, while applying tension to the belt-like member, individually interposed between the back and a floor surface. Thereby, the electrocardiograph electrode device is mounted on the subject as the electrode holder 50 is fixed using friction force generated on adhesion surfaces of the locking bodies 51a, 51b.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2019,JPO&INPIT【課題】心電計用電極装置について、被測定者に過大な負担をかけることなく電極を正確に位置決めしながら迅速に装着できるようにする。【解決手段】胸部用の電極10a,10b,10cがベルト状部材からなる電極ホルダ50の内側面で長手方向に複数個配置され、各電極10a,10b,10cが測定位置の皮膚に接するように被測定者の胸部に横向きに装着されて測定を行う心電計用電極装置1Aであって、そのベルト状部材の両端側には、所定形状の係止体51a,51bが各々付設されており、その係止体51a,51bを仰臥した被測定者の両腋下を通してベルト状部材に張力をかけながら背中と床面の間に各々挟み込むことにより、係止体51a,51bの密着面に生じる摩擦力で電極ホルダ50を固定しながら被測定者に装着される、ことを特徴とするものとした。【選択図】図1
