  • Patent number: 4799485
    Abstract: A neonatal subglottiscope set for emergency use comprises a plurality of subglottiscope tubes of various sizes suitable for neonatal use and a handle. These tubes are detachably connectable to the handle by means of a lever-operated latch. Each tube has a passage along its wall for receiving a fiberoptic light carrier, which is bent 90 degrees near its proximal end, and which has a locating pin receivable in a hole located in an ear on the handle. The entrance opening of the light carrier-receiving passage on its subglottiscope tube is positioned on the wall of the tube so that when the tube is attached to the handle, the entrance opening in all cases is at a uniform predetermined distance from the hole in the ear on the handle which receives the locating pin of the light carrier. Consequently, the same light carrier and handle can be used with all of the tubes in the set.
