The segment of a laryngoscope (i.e., rigid intubation type) intended to be inserted into the oral cavity to manipulate the tongue, preventing it from obstructing the oropharynx and enabling a clear view of the trachea for the insertion of an endotracheal (ET) tube prior to the delivery of inhalation anaesthesia and/or ventilation. It is connected to the laryngoscope handle and illumination of the airway is provided by a small built-in light bulb or a fibreoptic light. This device may be curved or straight and of various designs and lengths; it may be hinged/interchanged with the handle. Some types are magnetic resonance imaging (MRI) compatible. This is a single-use device.
