Plethysmogram sensor

Abstract

【課題】脈波の測定精度を高める。 【解決手段】脈波センサは、出力強度可変の発光部(LED1〜LED8の集合体を指す)と、前記発光部から照射されて被測定者の生体内を透過した光の強度を検出する受光部(PD)と、前記受光部から出力される測定値に基づいて前記被測定者の脈波に関する情報を取得する演算処理装置と、を有する。 【選択図】図3
PROBLEM TO BE SOLVED: To improve accuracy in measuring a pulse wave.SOLUTION: The plethysmogram sensor has a light emission part (set of LED 1-LED 8) that emits light of variable intensity, a light reception part (PD) for detecting the intensity of the light emitted from the light emission part to be transmitted through the living body of a person to be measured, and an operational processor for acquiring the data related to the pulse wave of the person to be measured on the basis of the measured value output from the light reception part.
