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. Removability of the subglottiscope tube from the handle allows the subglottiscope tube to be safely inserted in the larynx of the patient by eliminatng the possibility of exerting excessive leverage through the handle as the tube is inserted. The handle is a two-part handle having a first section directly attachable to the subglottiscope tube for manual movement of the tube after insertion, and the second section being attachable to the first section and usable to connect the subglottiscope tube to a laryngoscope support.
