Abstract
An airway device configured for intubation under blind or optionally under indirect vision of a fiber optic scope. It also configured to be used as a supraglottic airway device supporting external breathing or anesthesia circuits. The device comprises a tube system with expansion projections, a base, one or more inflation balloons, and a gastric suction tube. The device can include a stylet to guide endotracheal tube during intubation. The tube system can include an air tube and fiber-optic-probe tube. The balloon system can move the end of the tube system anteriorly to align it with the laryngeal opening. The balloon system can seal the airway leakage for low positive pressure ventilation for the device to operate as a supraglottic airway device. The inflation balloon and expansion projection can displace tissue that can block the airway path. The base can carry esophageal gastric drainage tube to the upper esophageal sphincter to block and drain gastric content regurgitation.
