Abstract
Description
実際の測定では真っ暗な環境で測定することはないので、所望の光による信号だけを得たいと思っても、外部の光が生体を経由してフォトダイオードで検出されることになる。
U9,U12,U13,U16,U17,U20,U21のピン番号8番に各々の信号をホールドするタイミングクロックが入力され、クロック部37のクロックに同期してフォトダイオード(PD)で検出された発光波長別の信号が保持されてピン番号5番にDC電圧で出力される。

Claims (2)
- センサー部と装置本体部とからなり、センサー部には近赤外線を照射する光源と、前記光源から一定の距離に配置されて光源からの透過光を受光する受光素子と、予めファントムによる透過光を測定して基準値として記録したROM部とからなり、装置本体部は、前記センサー部の受光信号により実際の吸光度を算出し、前記基準値と比較してベアーランバートの法則に適応して生体の酸素状態を演算する演算処理部を備えていることを特徴とするヘモグロビンの相対濃度変化と酸素飽和度測定装置。
- ファントムとセンサー部及び装置本体部とを備えた測定装置とからなり、前記ファントムは、光を完全に遮断する材質で形成された箱型のケース内の最下層にクッション材を敷き、その上に反射板、散乱層、吸収板、散乱層、吸収板を順次積層して形成されており、前記センサー部は、光源と、この光源から一定の距離に配置した受光素子と、前記ファントムの受光信号を基準値として記録するROMとからなり、前記装置本体部は、前記センサー部の受光信号により実際の吸光度を算出し、前記基準値と比較してベアーランバートの法則に適応して生体の酸素状態を演算する演算処理部を備えていることを特徴とするヘモグロビンの相対濃度変化と酸素飽和度測定装置。
