  • Patent number: 5775322
    Abstract: There is disclosed a tracheal tube for insertion into the trachea of a patient. The tracheal tube includes a tube portion having a distal end, and a signal source associated with the tube portion at a predefined distance from its distal end. The tracheal tube is inserted into the trachea such that the signal source is immediately posterior to the patient's cricothyroid ligament. Methods related to confirming proper placement of the tracheal tube by detecting the signal source immediately posterior to the patient's cricothyroid ligament are also disclosed.

  • Patent number: 5622169
    Abstract: There is disclosed an apparatus and method for locating a medical tube within the body of a patient. The medical tube is located by a detection apparatus which senses the static magnetic field strength gradient generated by a magnet associated with the medical tube and indicates the value of the gradient to the user. The detection apparatus is moved about the body of the patient until the greatest gradient magnitude is indicated. The detection apparatus distinguishes the field strength of the magnet associated with the medical tube from the earth's field strength by sensing the magnet's field strength at two different distances from the magnet.
