PROBLEM TO BE SOLVED: To lighten an endotracheal tube support device and the inside of an oral cavity using an optical fiber. SOLUTION: An endotracheal tube support device can lighten the inside of an oral cavity via optical fiber. Since it is lightened using the optical fiber, only operation of the endotracheal tube support device is required and therefore easiness of the operation is increased. A small penlight 2 is connected to a hard pipe 1 into which the optical fiber is inserted through a mounting tool 3. At this time, if an endotracheal tube is shorter than the pipe 1, a stopper 4 stops the endotracheal tube not to furthermore go to the depth.
