APPARATUS FOR OBSERVING TISSUE PERFUSION AND ITS FUNCTIONAL USAGE METHOD

摘要

PROBLEM TO BE SOLVED: To provide an apparatus which can easily be handled for observing tissue perfusion and is suitable for non-invasive minimal procedure during operation, which requires a specific protection means such as protection eyeglasses in particular. SOLUTION: A safety case 1 in which an infrared laser light source is integrally installed together with a CCD camera 2 consists of a compact unit for observing tissue perfusion. When the infrared laser light is irradiated on an operational range, indocyanine green intravenously injected to a patient in advance is excited to fluorescence before the excitation is detected with the CCD camera 2.
