Claims (11)
- 被験者の生体に近赤外光を照射するとともに前記生体からの反射光又は拡散光を受光する生体信号測定用の測定プローブと、該測定プローブを支持するとともに前記生体に接触するプローブ支持体と、該プローブ支持体に設けられて上記測定プローブを生体表面に対して直交する方向に移動させる駆動手段と、上記測定プローブの先端面と生体表面との接触を検知する接触検知手段とを備え、
上記駆動手段は、上記プローブ支持体が生体表面に接している状態で上記接触検知手段で検知される無負荷時の生体表面の位置から上記先端面を150μm遠ざけた位置と、上記先端面を無負荷時の生体表面よりも生体側に500μm突出する位置との範囲内に上記先端面を保持するものであることを特徴とする生体信号測定具。 - 上記接触検知手段は、上記測定プローブの先端面に配した電極によって電気的に接触を検知するものであることを特徴とする請求項1記載の生体信号測定具。
- 上記測定プローブの先端面を生体表面から浮かせる突起部を備えていることを特徴とする請求項1記載の生体信号測定具。
- 上記接触検知手段は、上記測定プローブを駆動手段で生体表面に対して直交する方向に移動させる間に上記測定プローブによって生体からの反射光又は拡散光を受光してスペクトルを測定するとともに、測定プローブを移動させつつ測定したスペクトルの変化を解析して測定プローブと生体表面との接触を検知するものであることを特徴とする請求項1記載の生体信号測定具。
- 上記測定プローブの先端面とプローブ支持体と生体表面とで囲まれる空間を外気に連通させる通気口を備えていることを特徴とする請求項1〜4のいずれか1項に記載の生体信号測定具。
- 上記通気口を開閉する開閉手段を備えていることを特徴とする請求項5記載の生体信号測定具。
- 上記通気口を通じて強制的に吸排する送風手段を備えていることを特徴とする請求項5または6記載の生体信号測定具。
- 上記送風手段が前記駆動手段を兼ねていることを特徴とする請求項7記載の生体信号測定具。
- 上記通気口を通って前記空間に至る空気の温度を生体温度に近づける温度調節手段を備えていることを特徴とする請求項5〜8のいずれかの1項に記載の生体信号測定具。
- 測定した生体信号を元に通気口を通じた通気流量または通気方向の少なくとも一方を制御する制御手段を備えていることを特徴とする請求項5〜9のいずれか1項に記載の生体信号測定具。
- 請求項1〜10のいずれか1項に記載の生体信号測定具を用い、測定プローブの先端面を無負荷時の生体表面から150μm遠ざけた位置から生体側に500μm突出させた範囲内に位置させて、この状態で近赤外光の生体に対する照射及び反射光または拡散光の受光を行うことを特徴とする生体信号測定方法。
