Artificial oral airway, esophageal blocker, and pharyngeal airway assembly

A pharyngeal airway assembly comprising:

• a main body comprising:
• a main body front end;
• a main body rear end;
• a bottom surface, a first side surface, a second side surface, and a top surface, wherein the first side surface corresponds to the second side surface and is connected to the bottom surface and the top surface, wherein the top surface is adapted to touch a tongue of a patient;
• at least one blocking strip mounted on the bottom surface, the first side surface, and the second side surface at the main body rear end of the main body;
• and
• an airway passing through the main body;
• and
• an esophageal blocker slidably received along the bottom surface in the airway and adapted to touch an esophageal inlet of the patient, wherein the esophageal blocker part comprises:
• an opening part touching the main body front end;
• an esophageal blocker part adapted to block the esophageal inlet of the patient;
• a slice body connecting the opening part and the esophageal blocker part, wherein the slice body is in a sheet-like shape having first and second, parallel, spaced surfaces and first and second spaced sides extending between and interconnecting the first and second, parallel, spaced surfaces;
• and
• two blocking portions and an indentation, wherein the indentation is situated between the two blocking portions, wherein the two blocking portions are adapted to cover the esophageal inlet and the indentation is adapted to touch a rear laryngeal wall of the patient when the esophageal blocker enters a mouth of the patient.
