<(1-1)生体情報測定装置1の構成>
この発明の一実施形態に係る生体情報測定装置1は、発光部4(発光素子)から発され被検生体(典型的には患者などの被検者)の指を透過した光を受光部5(受光素子)で受光し、当該受光部5から出力される信号に基づいて血液中の酸素飽和度に係るデジタル値(SpO2値)を取得するパルスオキシメータである。
図9および図10は、生体情報測定装置1の機能的な構成を示すブロック図である。
図11には、挿入孔3Hに指FG1が挿入されている状態における生体情報測定装置1の一形態が例示されている。
以上のように、本実施形態に係る生体情報測定装置1では、測定部2にパルスオキシメータの測定機能に係る基本的な電気的構成(発光部4、受光部5、電気回路6など)が完結している。このため、指受け部3は、これらの機能の一部を分担させる必要がなく、生体の指を保持可能で測定部2と一体化される機構であればよい。したがって、指受け部3がより容易にかつ低コストで製造されうる。

上記一実施形態に係る生体情報測定装置1では、アーム25が、受光部5と、伝送路26と、当該受光部5と当該伝送路26とを実装するフレキ27とを有する構成を採用していたが、これに限られるものではない。すなわち、アーム25の構成において必須の要件は、本体部20と一体形成されること、発光部4と受光部5とを光学的に対向するように受光部5を保持すること、本体部20と受光部5とを電気的に接続する伝送路26を有することであり、これらを満たす種々のアーム25を採用することができる。
上記一実施形態に係る生体情報測定装置1では、発光部4を本体部20側(+Z側)に配し、受光部5を当該発光部4と光学的に対向するようにフレキ27上(-Z側)に配する構成が示されていたが、これに限られるものではない。例えば、受光部5を本体部20側(+Z側)に配し、発光部4を当該受光部5と光学的に対向するようにフレキ27上(-Z側)に配する構成が採用されても良い。
(1) 光電素子対を用いた前記生体情報の光学的測定、および
