  • Guide device for endotracheal tubes
    Patent number: 4329983
    Abstract: A guide device for an endotracheal tube which assists in intubating the trachea. The guide device includes a flexible bar which may be inserted in the endotracheal tube. A flexible line extends along the bar and has a free length at the inner end of the bar. When the line is pulled, the free length shortens and causes the inner end portion of the bar to flex in bowed fashion against the endotracheal tube. This urges the tube forwardly toward the trachea and away from the esophagus.
