To control acquisition of waveforms on the basis of an approximation degree of a plurality of heart beat waveforms corresponding to a predetermined number of heart beats in a device for acquiring blood flow information.SOLUTION: A heart beat information acquisition device includes: a waveform acquisition unit for acquiring heart beat waveforms of one or a plurality of patients; a feature amount calculation unit for calculating a feature amount of the heart beat waveforms acquired by the waveform acquisition unit; an approximation degree calculation unit for calculating an approximation degree of the feature amount of the heart beat waveforms calculated by the feature amount calculation unit; and a control unit for controlling the acquisition of the heart beat waveforms by the waveform acquisition unit. The feature amount calculation unit calculates a feature amount of one heart beat waveform and feature amounts of other heart beat waveforms in a predetermined number of continuous heart beat waveforms in one patient. The approximation degree calculation unit calculates an approximation degree of a feature amount of one heart beat waveform and feature amounts of other heart beat waveforms. The control unit controls the acquisition of the heart beat waveforms by the waveform acquisition unit on the basis of the approximation degree calculated by the approximation degree calculation unit.SELECTED DRAWING: Figure 1 【課題】血流情報を取得する装置においては、所定数の心拍に対応する複数の心拍波形の近似度に基づいて、当該波形の取得を制御することが好ましい。【解決手段】１または複数の患者の心拍波形を取得する波形取得部と、波形取得部により取得された心拍波形の特徴量を算出する特徴量算出部と、特徴量算出部により算出された心拍波形の特徴量の近似度を算出する近似度算出部と、波形取得部による心拍波形の取得を制御する制御部と、を備え、特徴量算出部は、１人の患者において、予め定められた数の連続的な心拍波形における一の心拍波形の特徴量および他の心拍波形の特徴量を算出し、近似度算出部は、一の心拍波形の特徴量と、他の心拍波形の特徴量との近似度を算出し、制御部は、近似度算出部により算出された近似度に基づいて、波形取得部による心拍波形の取得を制御する、心拍情報取得装置を提供する。【選択図】図１
