  • Patent number: 10010688
    Abstract: An intubation system of the present disclosure intubates based on an airway pattern indicating a trachea opening. The airway pattern is determined from analysis of airway data detected by a trachea identifying device disposed on a moveable guide stylet of the intubation system. A navigation element is generated based on the airway pattern. In one embodiment, the airway pattern is a gas exchange pattern indicating a trachea opening. In another embodiment, the trachea opening transition pattern is a topographic pattern indicating a trachea opening. The guide stylet is capable of moving in a plurality of degrees of freedom in the airway following the guidance from the navigation element.
