Method and apparatus for ventilation / oxygenation during guided insertion of an endotracheal tube

A method for endotracheal intubation allows resuscitation of the patient to continue during intubation. A curved guide having a mask and a ventilation port is inserted into the patient's mouth and upper airway. The patient is initially resuscitated by supplying a flow of air/oxygen through the mask and simultaneously applying cardiac chest compressions. An endotracheal tube is inserted over the distal end of a fiber optic probe. Resuscitation continues without interruption while the fiber optic probe and endotracheal tube are advanced along the guide into the patient's airway, thereby allowing the physician to carefully guide the fiber optic probe and endotracheal tube to a position past the larynx while resuscitation continues.

Method and apparatus for endotracheal intubation using a light wand and curved guide

A method and apparatus for endotracheal intubation with simultaneous oxygenation/ventilation employs a curved guide and a light wand to ensure proper placement of the endotracheal tube in the patient's airway. The light wand has an elongated flexible member with a light source at its distal tip. The wand is inserted through an endotracheal tube until the light is adjacent to the distal end of the endotracheal tube. A curved guide is inserted into the patient's mouth and upper airway so that its distal end is positioned above the larynx. The wand and endotracheal tube are then advanced along the guide until the distal end of the endotracheal tube passes through the larynx and the light source is externally observable at a predetermined location through the anterior tracheal wall.

Cuffed oro-pharyngeal airway

A new type of airway, the cuffed oro-pharyngeal airway (COPA) (10), is described, which may be used as a less cumbersome alternative to face mask/oral airway technique for maintenance of general anesthesia. The airway includes an elongated tube (12) having a length such that the proximal end (20) is adapted to be disposed adjacent to, but outside, the oral cavity of the patient, and the distal end (36) is adapted to be disposed in the lower pharynx of the patient, above the epiglottis (26). An inelastic, inflatable cuff (14) is mounted to the tube adjacent the distal end (36). On inflation, the inflatable cuff displaces the soft palate against the nasal pharynx to seal off the nasal passages and defines a seal between the tube and the pharyngeal wall. The inflatable cuff (14) also displaces the base of the patient's tongue (30), thereby locking the tube in the pharynx and displacing the patient's epiglottis (26) to a more open disposition for more effective anesthesia gas delivery to the lungs.
