Abstract: The laryngo-tracheal analgesia endotracheal tube is a modification of existing endotracheal tubes. It has the addition of an injection port to a lumen in the wall of the tube with exiting holes that correspond to the anatomical position of the epiglottis, larynx and trachea when the tube is correctly placed. The device allows for topical anesthesia to be applied to these pain sensitive areas on ititial placement and while the tube remains in place. The endotracheal tube of the present invention allows a patient to tolerate the presence of an endotracheal tube without discomfort and potentially dangerous reflexes of coughing, gagging, hypertension and tachycardia.

Abstract: There is disclosed a device to be worn by a human patient for maintaining the upper airway passage of the patient in an open, unobstructed position. The device includes a lower portion arranged to rest upon the upper thorax of the patient and an upper portion connected to and braced by the lower portion. The upper portion includes means for lifting the lower jaw of the patient and thrusting the lower jaw of the patient forward. A posterior portion connected to the lower and upper portions maintains the positioning of the lower and upper portions and prevents backward movement of the patient's lower jaw.
