Abstract: A laryngoscope insertion section for a laryngoscope, which is typically a video laryngoscope, includes a lateral tube guide configured to retain an endotracheal tube in a plane. A viewing port for a camera or other image collector is laterally displaced from the plane of the endotracheal tube. The said plane of the endotracheal tube is aligned substantially in the same plane as a patient's median plane and the tube can be advanced into the larynx using a natural curving motion similar to the motion used to introduce an endotracheal tube using a convention laryngoscope. In a preferred embodiment, the distal tip of the insertion section and a retained endotracheal tube will be located in the patient's median plane during intubation. As the tube guide retains endotracheal tubes substantially in a plane, lateral curvature is avoided, reducing resistance to advancement of the tube.
