ELECTROCARDIOGRAPHIC SIGNAL MEASUREMENT DEVICE AND ELECTROCARDIOGRAPHIC SIGNAL MEASUREMENT SYSTEM

To provide a multi-channel type electrocardiographic signal measurement device having a plurality of electrocardiogram measuring parts for measuring an electrocardiographic signal capable of acquiring a clear electrocardiographic signal by suppressing noise.SOLUTION: An electrocardiogram measuring part 13 includes: a pair of positive and negative electrode bodies 20A and 21A composing a capacity coupling type electrode arranged to a human body in a non-contact state; a signal amplification part 23A for amplifying an electric signal from the two electrode bodes 20A and 21A, and outputting the same as an electrocardiographic signal; and a reverse output part 28A for reversing an in-phase signal of the electric signal from the two electrode bodies 20A and 21A, and outputting the same as a reverse signal. The electrocardiogram measuring part includes both of the two channels 13A and 13B at the same time when the electrocardiogram measuring part 13 in which the reverse signal from the reverse output part 28A is input to the positive electrode body 20A is stipulated as a first channel 13A, and when the electrocardiogram measuring part 13 in which the reverse signal from the reverse output part 28B is input to the negative electrode body 21B is stipulated as a second channel 13B.SELECTED DRAWING: Figure 1 【課題】心電信号を計測する心電計測部を複数個備える多チャンネル型の心電信号計測装置において、ノイズを抑えて明瞭な心電信号を得ることができる心電信号計測装置を提供する。【解決手段】心電計測部１３は、容量結合型電極を構成して人体に非接触状態で配される正負一対の電極体２０Ａ・２１Ａと、両電極体２０Ａ・２１Ａからの電気信号を増幅して心電信号として出力する信号増幅部２３Ａと、両電極体２０Ａ・２１Ａからの電気信号の同相信号を反転して、反転信号として出力する反転出力部２８Ａとを備える。反転出力部２８Ａからの反転信号が正電極体２０Ａに入力される心電計測部１３を第１チャンネル１３Ａと規定し、反転出力部２８Ｂからの反転信号が負電極体２１Ｂに入力される心電計測部１３を第２チャンネル１３Ｂと規定したとき、両チャンネル１３Ａ・１３Ｂを同時に備える。【選択図】図１
