An improved bronchofiberscope is provided that contains a sterile and uncontaminated distal end of an insertion tube with sleeves and a disolvable membrane over it to facilitate the distal end past vocal cords so that the sleeves can be pulled back releasing the disolvable membrane to expose the distal end whereby viewing of a windpipe and the branches is done with a light guide and an objective lens and removal of bronchial secretions is facilitated through a suction/forceps channel to remove an uncontaminated specimen for an appropriate bacteriologic examination.
