1. A supraglottic airway and esophageal blocker in combination comprising;
- an esophageal blocker;
a supraglottic airway including;
a respiratory tube;
a shield comprising a means for creating an airtight seal in the oropharyngeal region of a patient; and
a guide structure external to said respiratory tube and said means;
said guide structure being capable of guiding said esophageal blocker into an esophagus of said patient;
said guide structure is not directly connected to said shield;
wherein, while said supraglottic airway is inserted in said patient, said esophageal blocker can move relative to said supraglottic airway and can be extended through said guide structure to then extend past a distal end of said supraglottic airway into said esophagus of said patient.
