A set of indirect laryngeal tubes for purposes of emergency intubation and dilation of strictures is herewith shown and described. The tubes are fashioned to a great extent after the original hard rubber Schroetter tubes. They were made to overcome the disadvantages of the latter tubes. As the Schroetter tubes are made of hard rubber, they are difficult to manufacture. They are affected by heat so that they may straighten out and lose their original laryngeal curve. They deteriorate with age and become brittle so that they may break while being used and may cause embarrassment to both the patient and the laryngologist. They may break, even though new, when excessive force is applied.
In a case of syphilis of the larynx which required emergency treatment for obstructive laryngeal dyspnea, a Schroetter tube was employed which broke off at the incisors while being introduced. This caused considerable difficulty during the
