Abstract

A tongue root elevating instrument according to one aspect of the present invention comprises: a tubular accommodation part which has flexibility and in which an intubation tube for use in securing an airway is linearly accommodated; a notch part in which a tip part, of the accommodation part, to be inserted into a mouth can be curved and deformed; and a slit which allows the intubation tube accommodated in the accommodation part to be removed from a side surface of the accommodation part. The tip part is inserted into the mouth and then is curved to assist in insertion of the intubation tube into an indwelling position, and after the intubation tube is inserted into the indwelling position, the intubation tube can be removed through the slit and the tongue root elevating instrument can be removed from the mouth. The present invention can provide a tongue root elevating instrument that enables simple and easy operation of an intubation tube.
