PROBLEM TO BE SOLVED: To provide a blood pressure measuring device capable of measuring blood pressure continuously with a high degree of precision.SOLUTION: A blood pressure measuring device 10 includes a cuff 20 for compressing a blood vessel of a subject, a cuff pressure sensor for measuring a pressure pulse wave from a part compressed by the cuff, a photoelectronic sensor 30 for measuring a volume pulse wave from a reflected light of a light irradiated onto the blood vessel, and a data processing device 40. The blood pressure measuring device performs main measurement for measuring the volume pulse wave after preliminary measurement for measuring a reference volume pulse wave in measuring a reference pressure pulse wave accompanying a change in cuff pressure. The data processing device calculates a blood pressure value for each heart rate of the subject based on the reference pressure pulse wave of a plurality of pulses and a plurality of reference volume pulse waves acquired in the preliminary measurement.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】血圧を連続して高精度に測定することのできる血圧測定装置を提供する。【解決手段】血圧測定装置10は、被験者の血管を圧迫するカフ20と、カフによって圧迫された部分から圧脈波を測定するカフ圧センサと、血管に照射された光の反射光から容積脈波を測定する光電センサ30と、データ処理装置40とを備え、カフ圧の変化に伴う基準圧脈波の測定時に基準容積脈波を測定する予備測定の後に、容積脈波を測定する本測定を行う血圧測定装置であって、データ処理装置は、予備測定において得られた複数拍の基準圧脈波と、複数の基準容積脈波とに基づいて被験者の心拍毎の血圧値を算出する。【選択図】図3
