− 前記ヘッド部分に対して前記プローブカバーを移動させる工程と、
− 前記電子撮像ユニットを用いて少なくとも1枚の画像を捕捉する工程と、
− 特に前記鼓膜を加圧するために、前記プローブカバーを通して前記耳道に気体を入れる工程と
を含む方法によって、本発明に従って達成される。好ましくは、少なくとも1本の光軸は、径方向にオフセットして配置される。かかる方法を用いると、鼓膜を他の物体からより確実に識別することができる。特に、耳道内の可変圧に応答して鼓膜が移動するとき、複数の画像を捕捉することができるので、様々な物体の同定が容易になる。かかる方法により、耳道内のヘッド部分の位置に実質的に関係なく、光軸が鼓膜に向いているかどうかを決定することができる。かかる方法により、実用的な方法で非医師によって適用することが可能になる。
− ヘッド部分に気密に被せられている少なくとも部分的に透明なプローブカバーと併せて耳鏡の前記ヘッド部分を前記被験体の外耳の耳道に導入する工程であって、前記ヘッド部分が、少なくとも1本の光軸を示す光学電子撮像ユニットを収容している工程と
− 前記ヘッド部分に対して前記プローブカバーを移動させる工程と、
− 前記電子撮像ユニットを用いて少なくとも1枚の鼓膜の画像を捕捉する工程と、
− 前記プローブカバーを通して前記耳道に気体を入れる工程と
− 前記鼓膜の医学的証拠を提供するために、捕捉した前記少なくとも1枚の鼓膜の画像に基づいて前記鼓膜の可動性を評価し、前記鼓膜の医学的特徴付けを行う工程であって、前記鼓膜の医学的特徴付けが、前記鼓膜の湾曲、特に凸性を決定すること、前記鼓膜を加圧し、前記鼓膜の可動性を検出すること、及び前記鼓膜の温度を検出することの少なくともいずれかを含む工程とを含む。前記鼓膜の医学的特徴付けは、特に、例えば、温度又は特定の赤色度に関する所定の範囲に基づいて、装置によって自動的に実施されることが好ましい。
前記第1の湾曲C4’よりも鼓膜EDに近接している。耳鏡10のヘッド部分14は、耳道C内に導入される。耳鏡10は、第2の湾曲C4まで、即ち、おおよそ軟部結合組織C1と硬骨C2との間の移行領域C3まで耳道C内に導入される。図16に図示されている位置では、耳鏡10は、「角を見回す」ことができる。「角」は、耳道Cの第2の湾曲C4として定義することができる。耳鏡10は、加圧手段90をヘッド部分14の外側面に連結する少なくとも1本の第1の圧力線90.1と、加圧手段90をヘッド部分14の前側、即ち、遠位端18に配置されている遠位先端に連結する少なくとも1本の第2の圧力線90.2とを備える加圧手段90を有する。
