Abstract
The mask of a laryngeal mask assembly has a mount and an integral cuff at the patient end of a tube. The mount is of a thermoplastic material and the cuff is made by blow moulding from the material of the mount. A separate retaining plate seals an edge of the cuff with the mount and traps an inflation tube extending from the cuff to the inflation line of the tube.
