Abstract
A laryngeal airway device includes an air tube with proximal and distal ends, and a padded sealing member attached to the distal end of the air tube. The sealing member is padded on its anterior surface and is adapted to seat in the throat, against the hyoid bone, and to stretch the laryngeal inlet. A hole extends through the anterior surface padding of the sealing member and communicates through an air passage with the distal end of the air tube. When the sealing member is seated in the throat, the hole is contained within the rim of the stretched laryngeal inlet, with which the padded surface forms a seal that surrounds the hole. Airway patency is thereby ensured.
