Abstract
An intubation assistance device facilitates insertion of an endotracheal tube or a guide wire into a patient's trachea without requiring a laryngoscope. The device includes a curved flexible tubular member that has a proximal portion having a proximal end, a distal portion having a distal end, and a curved portion between the proximal portion and the distal portion. A lumen extends from the proximal end of the tubular member and terminates in the curved portion of the tubular member. The lumen is sized and shaped so that an endotracheal tube and/or a guide wire is axially moveable through the lumen. A ramp is disposed at a distal end of the lumen, and is angled to facilitate insertion of the endotracheal tube and/or guide wire into the patient's trachea. The distal portion of the tubular member includes an esophageal protrusion that is configured to be inserted in the patient's esophagus.
