Description
図1に示す静脈可視化装置1を用いて、腕部の静脈を観察した。静脈可視化装置1において、光源11は、指向角2θ1/2が128°、ピーク波長940nmのLEDを12個用いた。複数個の光源11は、各照射範囲が穿刺部位上で重畳するように配置した。光源11の各光軸L1と撮像部の光軸L2とのなす角度Aが15°〜60°の範囲に入るように光軸11を配置した。
光源11を指向角2θ1/2が44°、ピーク波長940nmのLEDに変更した以外は、実施例1と同様とした。
光源11を指向角2θ1/2が20°、ピーク波長940nmのLEDに変更した以外は、実施例1と同様とした。
光源11の各光軸L1と撮像部の光軸L2とのなす角度Aが0°〜10°の範囲に入るように光軸11の配置を変更した以外は、実施例1と同様とした。
光源11の各光軸L1と撮像部の光軸L2とのなす角度Aが65°〜120°の範囲に入るように光軸11の配置を変更した以外は、実施例1と同様とした。
