  • Patent number: 8244329
    Abstract: According to various embodiments, a tracheal tube may employ sensing techniques for determining a distance between the inserted tube and an anatomical structure such as a carina. The distance information may provide an indication as to whether or not the tracheal tube is properly placed within the trachea. Because a tracheal tube may rotate within the trachea, the sensing information may be gathered from multiple locations on the tracheal tube for a rotation-independent measurement technique.
    Type: Grant
