PROBLEM TO BE SOLVED: To provide a nerve stimulator capable of reducing invasion and troublesomeness.SOLUTION: The nerve stimulator 1 includes: a stimulation signal generation part 12 for generating nerve stimulation signals composed of a plurality of unit pulses an electrode part 20 having a pair of electrodes a heart rate measurement part 11 for acquiring electric information of a living body at a plurality of acquisition timings from the two electrodes including at least one of the pair of electrodes, and calculating a heart rate on the basis of the electric information a lead part 30 for connecting the electrode part, the stimulation signal generation part and the heart rate measurement part and a control part 13 for controlling the operations of the stimulation signal generation part and the heart rate measurement part. The control part sets the acquisition timing and the generation timing of the unit pulses so that the unit pulses are generated by the stimulation signal generation part between the acquisition timings and an interval of the unit pulse generation and the first acquisition timing after the unit pulse generation becomes equal to or larger than a prescribed value sufficient for the potential change of the living body caused by the unit pulses to disappear.COPYRIGHT: (C)2013,JPO&INPIT【課題】侵襲および煩わしさを低減することができる神経刺激装置を提供する。【解決手段】神経刺激装置1は、複数の単位パルスからなる神経刺激信号を発生する刺激信号発生部12と、一対の電極を有する電極部20と、一対の電極の少なくとも一方を含む二つの電極から複数の取得タイミングで生体の電気的情報を取得し、電気的情報にもとづいて心拍数を算出する心拍数計測部11と、電極部と、刺激信号発生部および心拍数計測部とを接続するリード部30と、刺激信号発生部および心拍数計測部の動作を制御する制御部13とを備え、制御部は、取得タイミング間に、刺激信号発生部により単位パルスが発生され、かつ単位パルスの発生時と、単位パルス発生後初めての取得タイミングとの間隔が、単位パルスにより生じる生体の電位変化が消失するのに充分な所定値以上となるように、取得タイミングと単位パルスの発生タイミングとを設定する。【選択図】図1
