PROBLEM TO BE SOLVED: To cause an electrocardiograph to reliably transmit electrocardiographic signals acquired from a living body.SOLUTION: An electrocardiograph connection part 200 is connected to an electrocardiograph which prepares an electrocardiogram. One end of a multi-core wire 300 is connected to the electrocardiograph connection part 200, and the other end is connected to an electrocardiographic induction wire 50 to which an electrode for acquiring the electrocardiographic signals from the living body is connected. The multi-core wire 300 and the electrocardiographic induction wire 50 are connected at a relay part 400. A connection part between the multi-core wire 300 and the electrocardiographic induction wire 50 is housed. The relay part 400 is electromagnetically shielded to prevent intrusion of external noise, and has a display lamp 450 for viewing the transmission state of the electrocardiographic signals.COPYRIGHT: (C)2013,JPO&INPIT【課題】生体から取得した心電信号を心電計に確実に伝送させる。【解決手段】心電計接続部200は心電図を作成する心電計に接続される。多芯電線300はその一端が心電計接続部200に接続されその他端が生体から心電信号を取得するための電極が接続される心電誘導電線50に接続される。多芯電線300と心電誘導電線50との接続は中継部400で行われ、多芯電線300と心電誘導電線50との接続部分が収納される。中継部400は外部ノイズの侵入を防止する電磁遮蔽が施され、心電信号の伝送状態を目視するための表示ランプ450を備える。【選択図】図1
