Abstract

See full text

A laryngeal mask assembly has a tubular shaft with a mask portion formed by a resilient skirt towards its patient end, which seals with tissue in the region of the hypopharynx. An inflatable cuff, with several annular reinforcing members, projects axially at the patient end of the assembly into the laryngeal inlet. Towards its patient end, the cuff has a flap that normally closes the passage through the cuff and prevents entry of the epiglottis. A pull cord attached with the flap enables the flap to be pulled to one side, deflecting the epiglottis and opening the passage through the cuff.
