Abstract: A pharyngeal intubation guiding device includes lengthwise extending tongue-side and palate-side walls that cooperatively define a guiding duct. The tongue-side wall is configured to conform to the rear end of a patient's tongue to permit the guiding duct to confront the opening of the patient's larynx. The palate-side wall has an outer contour which establishes a guideway towards the opening of the patient's esophagus. A lengthwise extending laryngoscope guiding channel and a lengthwise extending endotracheal tube guiding groove are disposed in the guiding duct. A viewing window is disposed to define a terminal end of the laryngoscope guiding channel. The endotracheal tube guiding groove has a lead-in port to permit an endotracheal tube introduced therein to be removable laterally. A lengthwise extending conduit is disposed in the guiding duct to permit an aspirator tube to reach the patient's trachea to suck out phlegm.
