Description
したがって、特許文献1,2などの装置によって被測定者の血圧値を常時取得することは難しく、結果として被測定者の重大疾病の発症・再発の予兆を捉えることも期待できない。血圧に限らず、他の生体情報を読取る場合についても同様のことが言える。
本明細書において「生体情報」とは、たとえば観血的動脈圧測定による血圧が110mmHgであるとか、グルコース分析装置(POCT)による血糖値が120mg/dlといった生体の状態についての情報として定義に沿った測定方法により得られた情報、あるいはカフ式血圧計のように医療界においても実質的な標準として広く認知される方法によって得られた情報である。
本発明の実施の形態に係る生体情報読取装置1の概要について、図1を参照しながら説明する。
動脈が皮下の浅い位置にある手首(掌側)付近などの部位では動脈の脈動による物理的振動が皮下の毛細血管へ強く影響し、これによって皮下ヘモグロビン量も大きく変動する。また、指先のような皮下の毛細血管密度が高い部位においても、動脈の脈動が皮下ヘモグロビン量に強く影響する。
これらの部位では脈波と同期して皮下ヘモグロビン量が変動することになるから、皮下ヘモグロビン量の変動から脈波を検出することが可能となる。
本発明の第二の実施の形態に係る生体情報読取装置1aを図11を参照しながら説明する。生体情報読取装置1と本実施の形態の生体情報読取装置1aとは一部が異なる。よって、生体情報読取装置1と同一の部材には、生体情報読取装置1と同一または同一系の符号を付すこととする。
本発明の第三の実施の形態に係る生体情報読取装置1bを図12を参照しながら説明する。生体情報読取装置1と本実施の形態の生体情報読取装置1bとは一部が異なる。よって、生体情報読取装置1と同一の部材には、生体情報読取装置1と同一または同一系の符号を付すこととする。
本発明の第四の実施の形態に係る生体情報読取装置1cを図13を参照しながら説明する。生体情報読取装置1と本実施の形態の生体情報読取装置1cとは一部が異なる。よって、生体情報読取装置1と同一の部材には、生体情報読取装置1と同一または同一系の符号を付すこととする。
本発明の第五の実施の形態に係る生体情報読取装置1dを図14を参照しながら説明する。本実施の形態の生体情報読取装置1dは、1枚の透過膜14a上に、複数の生体情報読取ユニット1eを配置する構成を有する。生体情報読取ユニット1eは、生体情報読取装置1,1a,または1bから透過膜14を除いたものである。
脈動検出部20、血圧測定部21、および警報発出部22は、それぞれ情報処理装置を有するが、1つの情報処理装置内に、これらの機能を実装してもよい。すなわち、脈動検出部20、血圧測定部21、および警報発出部22の出力部以外は、情報処理装置が予めインストールされている所定のプログラムを実行することによって実現することができる。このような情報処理装置は、たとえば、メモリ、CPU(Central Processing Unit)、入出力ポートなどを有する。情報処理装置のCPUは、メモリなどから所定のプログラムとして制御プログラムを読み込んで実行する。これにより、情報処理装置には、脈動検出部20、血圧測定部21、および警報発出部22の出力部以外の機能が実現される。なお、CPUの代わりにASIC(Application Specific Integrated Circuit)、マイクロプロセッサ(マイクロコンピュータ)、DSP(Digital Signal Processor)などを用いてもよい。
しかしながら、血流検出方式は光学を用いたもの以外を採用することも可能である。
