| description | PROBLEM TO BE SOLVED: To provide a pulse wave signal processing device that allows a pulse wave signal containing information necessary for estimating blood vessel hardness, blood pressure, etc. to be acquired.SOLUTION: In a pulse wave signal processing device 1, a pulse wave signal acquisition unit 13 acquires a pulse wave signal. A first filter unit 15 attenuates a frequency component of a first frequency or more in the pulse wave signal, etc. A second filter unit 17 attenuates a frequency component of a second frequency or more lower than the first frequency in the pulse wave signal. A feature point extraction unit 19 extracts a feature point in the pulse wave signal after the processing by the second filter unit. A division unit 21 divides the pulse wave signal, etc. after the processing by the first filter unit into sections of one pulse wave. An addition averaging unit 23 addition-averages a plurality of sections, overlapping them so that their feature points coincide.SELECTED DRAWING: Figure 2
【課題】血管硬さや血圧等の推定に必要な情報を含んだ脈波信号を得ることができる脈波信号処理装置を提供すること。【解決手段】脈波信号処理装置１において、脈波信号取得ユニット１３は、脈波信号を取得する。第１のフィルタユニット１５は、脈波信号等において、第１の周波数以上の周波数成分を減衰させる。第２のフィルタユニット１７は、脈波信号において、第１の周波数よりも低い第２の周波数以上の周波数成分を減衰させる。特徴点抽出ユニット１９は、第２のフィルタユニットによる処理後の脈波信号において、特徴点を抽出する。区分ユニット２１は、第１のフィルタユニットによる処理後の脈波信号等を、脈波の１拍の区間ごとに区分する。加算平均ユニット２３は、複数の区間を、特徴点が一致するように重ねて加算平均する。【選択図】図２ |
