Abstract

The present invention is composed of a set of Cannulas in which the Naso/Orogastric (C1) Cannula has a proximal opening (09); an upper Esophageal Balloon (20), located between the upper (08) and middle (14) portions, connected to a secondary lumen with an external Pilot Balloon (20A); and an Intragastric Balloon (17), in its lower portion, connected to a secondary lumen (12) with an external Pilot Balloon (17A). The Intragastric Balloon (17) has a sleeve, which forms a Transition Balloon (16) that fits in the esophageal-gastric junction (EG). The lower Esophageal Balloon (15) is connected to a secondary lumen (11) with an external Pilot Balloon (15A). The Naso/Oropharyngeal Cannula is blocked distally (18), but it has several Perforations (19). The Perilaryngeal Cannula (C2) has an opening (04) in the Exit Branch (01), a Connector (05) at the end of the Ventilatory Branch (02), an oropharyngeal balloon (03) connected to a secondary lumen with an external Pilot Balloon (3A), Perforations (07) in the distal end, and a distal opening (DO) to allow for the insertion of the Naso/Orogastric Cannula (C1).
