PROBLEM TO BE SOLVED: To calculate a biological risk of an external load.SOLUTION: A biological risk acquisition device 1 comprises: a physiological state acquisition part 3 which acquires a cardiac potential in an external load a pulse wave acquisition part 13 which acquires a pulse wave with a biological impedance a storage part 5 which holds a correspondence between the waveform of the pulse wave and biological risk information and a biological risk calculation part 7 which, in a case when a heart beat and a pulse wave are different from each other, calculates the biological risk information corresponding to the waveform of a pulse wave coincident with that of a cardiac potential, as the biological risk of the external load.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】外的負荷の生体リスクを算出する。【解決手段】生体リスク取得装置1は、外的負荷時の心電位を取得する生理状態取得部3と、生体インピーダンスにより脈波を取得する脈波取得部13と、脈波の波形と生体リスク情報との対応を保持する記憶部5と、心拍と脈拍とが異なる場合に、心電位の波形に一致する脈波の波形に対応する生体リスク情報を、外的負荷の生体リスクとする生体リスク計算部7とを備えている。【選択図】図1
