【０００１】
【発明の属する技術分野】
本発明は、患者の手指や足趾等に装着して、動脈血酸素飽和度を簡便かつ適正に測定することができるパルスオキシメータ用プローブおよびその装着方法に関するものである。
【０００２】
【従来の技術】
従来より、患者の動脈血酸素飽和度（ＳｐＯ２ ）を測定する場合において、一対の発光素子と受光素子とを生体組織の一部を介して対向配置し、前記生体組織を透過する光の強度を測定して動脈血酸素飽和度を測定するためのパルスオキシメータ用プローブが使用されている。
【０００３】
従来におけるこの種のパルスオキシメータ用プローブとしては、例えば患者の手指や足趾等に装着して、動脈血酸素飽和度を簡便かつ適正に測定することができるパルスオキシメータ用プローブとして、ワイヤケーブルの一端側を２方に分岐させ、その先端部に発光素子と検出素子とを接続してこれらの発光素子および検出素子をそれぞれケーシングに収納保持して発光部と検出部とを設け、前記ワイヤケーブルの他端部に前記発光部および検出部の発光素子および検出素子を前記ワイヤケーブルを介して外部接続を行うためのプラグを設けた検出器アセンブリを構成し、この検出器アセンブリの前記２方に分岐配置された発光部と検出部とに対して、これらを患者の手指や足趾等に装着する際に、外方からそれぞれクランプ挾持するように係合させて、前記発光部と検出部とを適正な対向する位置に保持し得るように、前記検出器アセンブリとは独立した構成からなる結合部材を設けた構成が開示されている（特許文献１参照）。
【０００４】
一方、図７に示すように、接続コード１２の一端側を２方に分岐１２ａ、１２ｂさせ、その先端部に発光素子と受光素子とを接続してこれらの発光素子および受光素子をそれぞれケーシングに収納保持して発光部１４と受光部１６とを設け、前記接続コード１２の他端部に前記発光部１４および受光部１６の発光素子および受光素子を前記接続コード１２を介して外部接続を行うためのコネクタ１８を設けてなるコード・コネクタ・アセンブリ１１において、前記発光部１４と受光部１６とを可撓性ブリッジ１５により結合した構成からなるパルスオキシメータ用プローブ１０が知られている。そして、このように構成したパルスオキシメータ用プローブ１０は、これを患者の手指や足趾等に装着する際に、前記発光部１４と受光部１６とを適正な対向する位置に保持するために、所要長さの巻着部材２２を設け、この巻着部材２２の一端側に粘着材を塗布した粘着部２５を形成すると共に、この粘着部２５に前記発光部１４と受光部１６の発光素子と受光素子にそれぞれ対応する位置にそれぞれ複数の位置決め穴２４ａ、２４ｂ、２４ｃを穿設し、前記巻着用テープ２２の他端側に面ファスナ２７を設けて、前記パルスオキシメータ用プローブ１０の装着アダプタ２０として、前記発光部１４と受光部１６とを巻き付け固定するように構成したものが知られている。
【０００５】
また、図８に示すように、接続コード１２の一端側を２方に分岐１２ａ、１２ｂさせ、その先端部に発光素子と受光素子とを接続してこれらの発光素子および受光素子をそれぞれケーシングに収納保持して発光部１４と受光部１６とを設け、前記接続コード１２の他端部に前記発光部１４および受光部１６の発光素子および受光素子を前記接続コード１２を介して外部接続を行うためのコネクタ１８を設けたコード・コネクタ・アセンブリ１１′を備えた構成からなるパルスオキシメータ用プローブ１０′が市販されている。そして、このように構成されたパルスオキシメータ用プローブ１０′は、これを患者の手指や足趾等に装着する際に、前記発光部１４と受光部１６とを適正な対向する位置に保持するために、所要長さの巻着用粘着テープ２３を設け、この粘着テープ２３の一端側に前記発光部１４と受光部１６の発光素子と受光素子とのそれぞれ対応する位置にそれぞれ位置決め穴２４ａ、２４ｂを穿設して、前記パルスオキシメータ用プローブ１０′の装着テープ２１として、前記発光部１４と受光部１６とを巻き付け固定するように構成したものが使用されている。

【０００７】
【発明が解決しようとする課題】
しかるに、前述した従来のパルスオキシメータ用プローブにおいては、発光部１４と受光部１６とを、患者の手指や足趾等の生体組織の装着部位ＴＰ に装着する際に、例えば図９の（ａ）に示すように、前記発光部１４と受光部１６とを適正な対向する位置に保持することが、精度の高い動脈血酸素飽和度の測定を行うのに不可欠である。
【０００８】
しかしながら、図７に示す構成からなるパルスオキシメータ用プローブ１０においては、発光部１４と受光部１６とが可撓性ブリッジ１５により結合されているため、例えば生体組織の装着部位ＴＰ が小さい場合には、図９の（ｂ）に示すように、可撓性ブリッジ１５の寸法が長過ぎて、発光部１４と受光部１６とが適正な対向する位置とならなくなる。そこで、この場合に、発光部１４と受光部１６とを適正な対向する位置となるように調整するには、図９の（ｃ）に示すように、可撓性ブリッジ１５が生体組織の装着部位ＴＰ から離反して不安定な状態となる。そして、このような状態において、図９の（ｄ）に示すように、装着アダプタ２０を使用して、前記発光部１４と受光部１６との位置を固定しようとしても、生体組織の装着部位ＴＰ から離反する可撓性ブリッジ１５の周囲を囲繞するため、巻着隙間Ｇができて、前記発光部１４と受光部１６との固定が不安定となる難点がある。
【０００９】
また、生体組織の装着部位ＴＰ が大きい場合には、図９の（ｅ）に示すように、可撓性ブリッジ１５の寸法が短過ぎて、発光部１４と受光部１６とが適正な対向する位置とならなくなる。従って、このような場合には、前記発光部１４と受光部１６とを適正な対向する位置に調整することは、全く困難となる。
【００１０】
一方、図８に示す構成からなるパルスオキシメータ用プローブ１０′おいては、可撓性ブリッジ１５（図７参照）が省略されているため、発光部１４と受光部１６とも自由に移動可能であるが、これらの発光部１４と受光部１６とを生体組織の装着部位ＴＰ に位置決め固定するに際して、装着テープ２１の位置決め穴２４ａ、２４ｂに、それぞれ前記発光部１４と受光部１６の発光素子と受光素子とが位置決めされる。このため、前記と同様にして、生体組織の装着部位ＴＰ が小さい場合や大きい場合には、前記発光部１４と受光部１６とを適正な対向する位置に調整することが困難となる。
【００１１】
なお、前記特許文献１に記載のパルスオキシメータ用プローブにおいては、ワイヤケーブルの一端側を２方に分岐させてその先端部に発光部と検出部とを設け、た検出器アセンブリに対して、前記検出器アセンブリとは独立した構成からなる結合部材を使用して、前記発光部と検出部とを適正な対向する位置に保持し得るように、外方からそれぞれクランプ挾持するように係合するものであり、前記発光部と検出部とを適正な位置に位置決めすることが面倒であり、その固定も不安定となる等の難点がある。
【００１２】
そこで、本発明者等は、鋭意研究並びに検討を重ねた結果、一端部において発光素子および受光素子とコード接続を行うと共に、他端部において前記発光素子および受光素子の外部接続を行うためのコネクタ部を設けたコード・コネクタ・アセンブリと、このコード・コネクタ・アセンブリの一端側を２方に分岐させ、その先端部に前記発光素子と受光素子とを接続してこれらの発光素子および受光素子をそれぞれ外装カバーに収納保持してなる発光部および受光部とからなり、前記発光部および受光部を生体組織の装着部位を介して対向配置し、前記生体組織を透過する光の強度を測定して動脈血酸素飽和度を測定するように構成したパルスオキシメータ用プローブを構成し、前記コード・コネクタ・アセンブリのそれぞれ２方に分岐したコードの先端部にそれぞれ設けた発光部および受光部のコード接続側基部に、前記発光部と受光部とを相互に橋絡係止すると共に、前記コードに対してスライド可能に装着したスライド・アダプタを設けた構成とすることにより、生体組織の装着部位の大きさの変化に対応して、前記スライド・アダプタを適宜コード・コネクタ・アセンブリのコードの長手方向に移動調整することによって、容易かつ簡便に前記発光部と受光部とを適正な対向する位置に位置決めすることができる、パルスオキシメータ用プローブが得られることを突き止めた。
【００１３】
すなわち、前記スライド・アダプタは、可撓性材料によりほぼＵ字状に成形加工して、その両端部を２方に分岐された前記コード・コネクタ・アセンブリの各コードにそれぞれスライド可能に挿通すると共に、前記発光部および受光部を形成する外装カバーのコード接続側基部に係脱可能に装着することにより、生体組織の装着部位が標準的寸法またはそれより小さい場合には、スライド・アダプタを移動させることなく装着し、生体組織の装着部位が標準的寸法より大きい場合には、適宜スライド・アダプタを移動させて、発光部と受光部とを適正な対向する位置に位置決めすることが可能となる。
【００１４】
また、前記発光部と受光部とを接続するため、前記コード・コネクタ・アセンブリのコードを２方に分岐させる分岐点を形成するコード締結部を、予め各コードを２方に離間させて分岐するようにＹ字形状に構成したり、あるいは予め各コードを所要の角度をもって２方向に拡開導出するように構成することによって、前記スライド・アダプタのスライド調整機能を有効に発揮させることができることを突き止めた。
【００１５】
さらに、前記発光部および受光部を形成する外装カバーは、生体組織の装着部位に対して密着可能な湾曲部を有する外向きフランジを備えることにより、発光素子と受光素子とによる生体組織の装着部位を透過する光の外乱を防止して、常に安定した透過光の強度の測定を達成することができる。また、前記発光部を形成する外装カバーについては、発光素子の発光面に対する背面側に発光部を表すための識別表示を施すことにより、生体組織の装着部位に対する発光部と受光部とを適正な位置に装着するための作業を容易化ないし円滑化している。
【００１６】
なお、前述した構成からなる本発明のパルスオキシメータ用プローブにおいては、前記発光部および受光部を、生体組織の装着部位に対してスライド・アダプタを巻き込むことなく、装着アダプタまたは装着テープを巻着して、それぞれ適正な対向位置となるように装着固定することにより、前記発光部と受光部との位置決め固定も、迅速にして安定かつ確実に行うことができることを突き止めた。
【００１７】
従って、本発明の目的は、コード・コネクタ・アセンブリの一端側を２方に分岐させ、その先端部に発光素子と受光素子とを接続してこれらをそれぞれ外装カバーに収納保持してなる発光部および受光部により、生体組織の装着部位を透過する光の強度を測定して動脈血酸素飽和度を測定するように構成したパルスオキシメータ用プローブにおいて、前記発光部および受光部を適正な対向する位置に、簡便かつ容易に位置決め保持することができるようにしたパルスオキシメータ用プローブおよびその装着方法を提供することにある。
【００１８】

【００２２】
本発明の請求項５に記載のパルスオキシメータ用プローブは、前記発光部および受光部を形成する外装カバーを、生体組織の装着部位に対して密着可能な湾曲部を有する外向きフランジを備えてなることを特徴とする。
【００２３】

本発明の請求項７に記載のパルスオキシメータ用プローブの装着方法は、前記請求項１ないし６のいずれかに記載のパルスオキシメータ用プローブを、前記発光部および受光部を、生体組織の装着部位に対してスライド・アダプタを巻き込むことなく、装着アダプタまたは装着テープを巻着して、それぞれ適正な対向位置となるように装着固定することを特徴とする。
【００２５】
【発明の実施の形態】
次に、本発明に係るパルスオキシメータ用プローブおよびその装着方法の実施の形態につき、添付図面を参照しながら詳細に説明する。
【００２６】
図１は、本発明に係るパルスオキシメータ用プローブの一実施例を示す概略構成斜視図である。すなわち、図１において、参照符号３１はコード・コネクタ・アセンブリを示し、このコード・コネクタ・アセンブリ３１の接続コード３２の一端側を２方に分岐３２ａ、３２ｂさせ、その先端部に発光素子と受光素子とを接続してこれらの発光素子および受光素子をそれぞれ外装カバー３３、３５に収納保持してなる発光部３４と受光部３６とを設ける。また、前記接続コード３２の他端部には、前記発光部３４および受光部３６の発光素子および受光素子を前記接続コード３２を介して外部接続を行うためのコネクタ３８が設けられている。
【００２７】
そこで、本実施例におけるパルスオキシメータ用プローブ３０は、前記コード・コネクタ・アセンブリ３１のそれぞれ２方に分岐した接続コード３２ａ、３２ｂの先端部にそれぞれ設けた発光部３４および受光部３６のコード接続側基部３３ａおよび３５ａに、前記発光部３４と受光部３６とを相互に橋絡係止すると共に、前記接続コード３２ａ、３２ｂに対してスライド可能に装着したスライド・アダプタ４０を設けたことを特徴とする。なお、参照符号３７は、前記コード・コネクタ・アセンブリ３１の発光部３４および受光部３６の発光素子および受光素子を接続するために、接続コード３２を２方に分岐させる分岐点を形成する接続コード締結部を示す（図１参照）。
【００２８】
前記スライド・アダプタ４０は、例えばウレタンゴム等の可撓性材料により、図示のようにほぼＵ字状に成形加工され、その両端部を２方に分岐されたコード・コネクタ・アセンブリ３１の各接続コード３２ａ、３２ｂに、それぞれスライド可能に挿通すると共に、発光部３４および受光部３６を形成する外装カバー３３および３５のコード接続側基部３３ａおよび３５ａに、係脱可能に装着し得るよう構成する（図１参照）。
【００２９】
図２の（ａ）〜（ｅ）は、前述した発光部３４および受光部３６を構成する外装カバー３３および３５の構成を示すものである。すなわち、図２の（ａ）〜（ｃ）は、前記外装カバー３３および３５の共通する構成を示すもので、外装カバー３３（３５）の生体組織の装着部位に対する装着面側を、図２の（ａ）、（ｂ）に示すように、前記生体組織の装着部位に対して密着可能となる湾曲部３３ｂ、３３ｂ（３５ｂ、３５ｂ）を形成した左右対称の外向きフランジ３３ｃ、３３ｃ（３５ｃ、３５ｃ）を備えた構成としたことを特徴とするものである。なお、前記外装カバー３３（３５）の生体組織の装着部位に対する装着面側には、図２の（ｃ）、（ｄ）に示すように、前述した発光部３４および受光部３６の発光面および受光面を、それぞれ透過被覆する透明被覆体を外部に露呈するための窓部３３ｄ（３５ｄ）が設けられる。
【００３０】
また、前記発光部３４を形成する外装カバー３３については、図２の（ｅ）に示すように、前述した窓部３３ｄを設けた生体組織の装着部位に対する装着面側とは反対側面に、発光部を表すための識別表示３３ｅを施す。このように構成することにより、本実施例のパルスオキシメータ用プローブ３０を生体組織の装着部位に装着する場合に、発光部３４を簡便に識別して、装着作業を迅速かつ円滑に行うことができる利点が得られる。
【００３１】
図３の（ａ）および（ｂ）は、前記コード・コネクタ・アセンブリ３１の発光部３４および受光部３６の発光素子および受光素子を接続するために、接続コード３２を２方に分岐させる分岐点を形成する接続コード締結部３７の変形例を示すものである。すなわち、図３の（ａ）に示す接続コード締結部３７は、予め各接続コード３２ａ、３２ｂを、２方に離間させて分岐するようにＹ字形状に構成したものである。また、図３の（ｂ）に示す接続コード締結部３７は、予め各接続コード３２ａ、３２ｂを、所要の角度をもって２方向に拡開導出するように構成したものである。
【００３２】
図４の（ａ）および（ｂ）は、本実施例におけるパルスオキシメータ用プローブ３０に設けたスライド・アダプタ４０の操作方法を示すものである。すなわち、生体組織の装着部位が標準的寸法またはそれより小さい場合、スライド・アダプタ４０は、発光部３４および受光部３６を形成する外装カバー３３および３５のコード接続側基部３３ａおよび３５ａに係止させた状態で使用することができる〔図４の（ａ）参照〕。一方、生体組織の装着部位が標準的寸法より大きい場合には、スライド・アダプタ４０を、分岐された接続コード３２ａ、３２ｂに沿ってスライドさせて、前記発光部３４と受光部３６とを適正な対向する位置に配置することができる〔図４の（ｂ）参照〕。
【００３３】
図５の（ａ）および（ｂ）は、本実施例におけるパルスオキシメータ用プローブ３０の発光部３４と受光部３６とを、適正な対向する位置に位置決めするための装着方法の一例を示すものである。例えば、生体組織の装着部位Ｔｐ （足趾）が標準的寸法より大きい場合は、図５の（ａ）に示すように、発光部３４と受光部３６とを適正な対向する位置に位置決めすることができない。そこで、前述したように、スライド・アダプタ４０を、分岐された接続コード３２ａ、３２ｂに沿って適宜スライドさせることにより、図５の（ｂ）に示すように、前記発光部３４と受光部３６とを適正な対向する位置に配置することができる。なお、生体組織の装着部位Ｔｐ が標準的寸法より小さい場合は、後述するように、装着アダプタまたは装着テープを使用して、発光部３４と受光部３６とを適正な対向する位置に位置決めした発光部３４と受光部３６の外周に巻着して、前記発光部３４と受光部３６とを安定かつ確実に装着固定することができる。
【００３４】
図６の（ａ）〜（ｄ）は、本実施例におけるパルスオキシメータ用プローブ３０を、生体組織の装着部位の適正な対向する位置に位置決め固定するため、従来より知られている装着アダプタまたは装着テープを使用するパルスオキシメータ用プローブ３０の装着方法を示すものである。すなわち、図６の（ａ）〜（ｃ）は、生体組織の装着部位Ｔｐ として、手指、足趾および足の甲に対し、それぞれ装着アダプタ５０を使用して、適正な対向する位置に位置決めした発光部３４と受光部３６との外周に巻着する場合を示す。この場合、装着アダプタ５０は、いずれもスライド・アダプタ４０を巻き込むことなく、発光部３４と受光部３６とを安定かつ確実に装着固定することができる。また、図６の（ｄ）は、装着テープ５２を使用する場合を示し、この場合にも前記装着アダプタ５０と全く同様に、生体組織の各種装着部位Ｔｐ に対し、適正な対向する位置に位置決めした発光部３４と受光部３６との外周に巻着することができる。従って、本実施例によれば、特に生体組織の装着部位Ｔｐ が標準的寸法より小さい場合に、前記スライド・アダプタ４０を巻き込むことなく、装着アダプタ５０または装着テープ５２を巻着することができるので、発光部３４と受光部３６とを適正な対向する位置に、安定かつ確実に固定することができる利点が得られる。
【００３５】
以上、本発明の好適な実施例について説明したが、本発明は前記実施例に限定されることなく、本発明の精神を逸脱しない範囲内において、多くの設計変更を行うことができる。
【００３６】
【発明の効果】
以上、詳述したように、本発明の請求項１に記載のパルスオキシメータ用プローブによれば、コード・コネクタ・アセンブリの一端側を２方に分岐させ、その先端部に発光素子と受光素子とを接続してこれらをそれぞれ外装カバーに収納保持してなる発光部および受光部を、適正な対向する位置に、簡便かつ容易に位置決め保持することができる。
【００３７】
また、請求項２に記載のパルスオキシメータ用プローブによれば、スライド・アダプタの構成によって、生体組織の装着部位が標準的寸法またはそれより小さい場合には、スライド・アダプタを移動させることなく装着し、生体組織の装着部位が標準的寸法より大きい場合には、適宜スライド・アダプタを移動させて、発光部と受光部とを適正な対向する位置に配置することが可能となる。
【００３８】
また、請求項３および４に記載のパルスオキシメータ用プローブによれば、発光部と受光部とを接続するためのコード・コネクタ・アセンブリのコードを２方に分岐させるコード分岐点となる締結部の構成を改善することにより、スライド・アダプタのスライド調整機能をより有効に発揮させることができる。
【００３９】

[0006]
[Patent Document 1]
U.S. Pat. No. 5,800,349 (column 9, line 54 to column 10, line 25, FIGS. 9-11).
[0007]
[Problems to be solved by the invention]
However, in the conventional pulse oximeter probe described above, when the light-emitting unit 14 and the light-receiving unit 16 are attached to the attachment site TP of a living tissue such as a finger or a toe of a patient, for example, FIG. As shown in ()), it is indispensable to hold the light emitting unit 14 and the light receiving unit 16 at appropriate opposing positions in order to measure the arterial blood oxygen saturation with high accuracy.
[0008]
However, in the pulse oximeter probe 10 having the configuration shown in FIG. 7, since the light emitting unit 14 and the light receiving unit 16 are connected by the flexible bridge 15, for example, when the mounting portion TP of the living tissue is small. In FIG. 9B, as shown in FIG. 9B, the size of the flexible bridge 15 is too long, and the light emitting unit 14 and the light receiving unit 16 are not located at appropriate positions facing each other. Therefore, in this case, in order to adjust the light-emitting unit 14 and the light-receiving unit 16 to be in appropriate opposing positions, as shown in FIG. It is separated from the part TP and becomes an unstable state. In such a state, as shown in FIG. 9D, even if the mounting adapter 20 is used to fix the positions of the light emitting unit 14 and the light receiving unit 16, the mounting portion TP of the living tissue is fixed. There is a problem in that the periphery of the flexible bridge 15 that separates from the surroundings forms a winding gap G, and the fixing between the light emitting unit 14 and the light receiving unit 16 becomes unstable.
[0009]
In addition, when the attachment portion TP of the living tissue is large, as shown in FIG. 9E, the size of the flexible bridge 15 is too short, and the light emitting unit 14 and the light receiving unit 16 are appropriately opposed to each other. Will not be in position. Therefore, in such a case, it is quite difficult to adjust the light emitting unit 14 and the light receiving unit 16 to appropriate opposing positions.
[0010]
On the other hand, in the pulse oximeter probe 10 'having the configuration shown in FIG. 8, since the flexible bridge 15 (see FIG. 7) is omitted, both the light emitting unit 14 and the light receiving unit 16 can be freely moved. However, when the light emitting unit 14 and the light receiving unit 16 are positioned and fixed to the mounting portion TP of the living tissue, the light emitting elements of the light emitting unit 14 and the light receiving unit 16 are respectively positioned in the positioning holes 24a and 24b of the mounting tape 21. The light receiving element is positioned. For this reason, similarly to the above, when the attachment site TP of the living tissue is small or large, it is difficult to adjust the light emitting unit 14 and the light receiving unit 16 to appropriate opposing positions.
[0011]
In the pulse oximeter probe described in Patent Literature 1, one end of the wire cable is branched into two sides, and a light emitting unit and a detecting unit are provided at the distal end thereof. The light emitting portion and the detecting portion are engaged with each other from outside so that the light emitting portion and the detecting portion can be held at appropriate opposing positions using a coupling member having a structure independent of the detector assembly. However, it is troublesome to position the light emitting unit and the detecting unit at appropriate positions, and there is a problem that the fixing is also unstable.
[0012]
Therefore, the inventors of the present invention have conducted intensive studies and studies, and as a result, at one end, a light emitting element and a light receiving element are connected with a cord, and at the other end, a connector for externally connecting the light emitting element and the light receiving element. A light-emitting element and a light-receiving element are connected to the leading end of the code-connector assembly, and the light-emitting element and the light-receiving element are connected to the end of the code connector assembly. Each comprising a light-emitting part and a light-receiving part housed and held in an exterior cover, the light-emitting part and the light-receiving part are arranged to face each other via a living tissue mounting portion, and the intensity of light transmitted through the living tissue is measured. A pulse oximeter probe configured to measure arterial oxygen saturation was configured and bifurcated to each of the cord connector assemblies. The light emitting section and the light receiving section are bridge-locked to each other at the base of the cord connecting side of the light emitting section and the light receiving section respectively provided at the tip of the cord, and the slide section is slidably mounted on the cord. With the configuration provided with the adapter, the slide adapter is appropriately moved in the longitudinal direction of the cord of the cord connector assembly in accordance with the change in the size of the mounting portion of the living tissue, so that it is easy and It has been ascertained that a pulse oximeter probe that can easily position the light emitting section and the light receiving section at appropriate opposing positions is obtained.
[0013]
That is, the slide adapter is formed into a substantially U-shape from a flexible material, and both ends thereof are slidably inserted into the cords of the cord connector assembly branched into two sides, respectively. By detachably attaching to the cord connection side base of the outer cover forming the light emitting unit and the light receiving unit, the slide adapter is moved when the attachment portion of the living tissue is a standard size or smaller. In the case where the body is mounted without being attached and the body tissue mounting portion is larger than the standard size, the slide adapter can be moved as appropriate to position the light emitting unit and the light receiving unit at appropriate opposing positions.
[0014]
Further, in order to connect the light emitting unit and the light receiving unit, a cord fastening unit forming a branch point for branching the cord of the cord connector assembly into two directions is branched by separating each cord in advance in two directions. As described above, it is possible to effectively exhibit the slide adjusting function of the slide adapter by forming the cord into a Y-shape or by previously expanding each cord in two directions at a required angle. I found it.
[0015]
Further, the exterior cover forming the light emitting portion and the light receiving portion includes an outward flange having a curved portion that can be in close contact with the mounting portion of the living tissue, so that the mounting portion of the living tissue by the light emitting element and the light receiving element is provided. It is possible to prevent the disturbance of the light transmitted through the light source and always achieve a stable measurement of the transmitted light intensity. Further, for the exterior cover forming the light emitting portion, by providing an identification display for indicating the light emitting portion on the back side with respect to the light emitting surface of the light emitting element, the light emitting portion and the light receiving portion with respect to the mounting portion of the living tissue can be properly adjusted. This facilitates or facilitates the work for mounting in position.
[0016]
In the pulse oximeter probe of the present invention having the above-described configuration, the light-emitting unit and the light-receiving unit are wound around a mounting adapter or a mounting tape without involving a slide adapter around the mounting site of the living tissue. Then, it has been found that by fixing the light-emitting portion and the light-receiving portion to each other by fixing them so as to be at appropriate opposing positions, the positioning and fixing of the light-emitting portion and the light-receiving portion can be performed quickly, stably and reliably.
[0017]
