VME-6B Video Bronchoscope is applied for medical institution to observe, diagnosis and treat patient’s trachea and bronchi. With high resolution of CCD built-in, it increases images resolution and color reducibility, and makes tiny color difference observed of mucosal surface more clearly when compare with fiber bronchoscope. It also inserts tube much easier into patient’s trachea and bronchi due to wide view of field of video bronchoscope.
