Abstract

See full text

The mask at the end of a laryngeal mask assembly is made from a flexible cylindrical member having radially projecting ledges at each end. The ends of the cylindrical member are folded axially within the member to form an annulus with an inner rib formed by the contacting ledges. One side of the rib is located in a channel around an elliptical mount member at the patient end of a tube. The other side of the rib is located in a channel around a plate, which is attached to the mount member trapping the rib between the plate and the mount member so that a cuff is formed extending around the mount member.
