Abstract:
1. A larynx mask suitable for insertion through the middle of the pharynx via the epiglottis, comprising: (a) a cover plate with a tube insertion connector, a respiration lumen opening, and an oesophageal passage; and (b) an inflatable cuff peripherally surrounding the cover plate on a ventral side of the cover plate, wherein the cover plate extends distally over the cuff, wherein the oesophageal passage emerges from the cover plate before a distal end of the cover plate on a dorsal side of the cover plate and passes over the cuff as an open channel in the cover plate, and wherein reinforcing means are provided on both sides of the open channel that act approximately parallel to a longitudinal axis of the open channel and thereby counteract possible kinking of a distal tip of the larynx mask; (c) reinforcing walls running ventro-dorsally on each side of the open channel, whereby the distal tip of the larynx mask is reinforced against kinking; wherein the reinforcing walls are arranged parallel to the open channel and are offset by a distance from the open channel, and a channel widening in the form of an offset projection is provided between the open channel and the reinforcing walls on each side of the open channel.
