LARYNGEAL MASK WITH FOAM CUFF

摘要

A laryngeal mask airway has a foam cuff 16 formed on the patient surface of a plate 20 attached at the patient end 14 of a tube 1. The cuff 16 is of a self-skinning foam so that the skin 24 of the foam forms the outer surface of the cuff and seals with the plate 20. An air lumen 2 extruded along the tube 1 opens at one end into the interior of the cuff 16 and at the other end connects with an air line 3. The cuff 16 can be compressed for insertion and removal by applying suction to the air line 3.
