US 2011/0226256 A1 · LARYNX MASK HAVING A CONNECTOR

Abstract

The invention relates to a larynx mask comprising a dorsal cover plate with an inflatable cuff integrally formed thereon and a tube connecting connector to a plug region having an adjoining insertion section for connecting to an insertion tube. Two separate lumens are provided in the region of the insertion section, these being the esophageal lumen and a respiration lumen. Said two lumens are separated from each other by a separating or supporting wall. Said separating or supporting wall runs from the insertion section to the tip of the larynx mask. While the esophageal lumen opens into the esophageal outlet at the proximal end, the respiration lumen opens in the ventral direction, while the lumen is closed in the proximal direction close to the tip. Such a larynx mask can be produced in one piece by way of injection molding and at the same time is reinforced by the separating or supporting wall to prevent kinking.
