Instructional device for use of a bronchoscope

摘要

A hollow body is in the shape of a tracheobronchial tree having a plurality of segments. The hollow body is supported in a carrying container so as to be hidden from view while having its entrance opening disposed to receive a bronchoscope operated by a trainee. The hollow body has forty openings at various locations for various segments of the tree with each opening having one end of a fiber optic bundle disposed therein. The other end of each of the fiber optic bundles is supported in an opening in a backing plate. A photographic print of a drawing of a tracheobronchial tree having the same segments as the model is secured to the upper surface of the backing plate. Each of the openings in the backing plate is aligned with an opening in the print so that a light from the probe of the bronchoscope illuminates the same segment of the tracheobronchial tree of the print as the segment of the hollow body having the probe of the bronchoscope inserted therein. Viewing of the print by the trainee can be prevented so that testing of the trainee may be accomplished.
