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.

1 . A larynx mask comprising a dorsal cover plate with a circumferential inflatable cuff formed thereon and a tube connecting connector for connecting to at least one insertion tube, which comprises an air supply lumen and an oesophageal lumen, whereby the tube connecting connector has an insertion section, wherein there is a separating and supporting wall running from dorsal to ventral, which is formed at least approximately centrally on the cover plan and runs in a longitudinal direction of the larynx mask passing through it from distal to at least approximately its dorsal end and forming the partition between a closed lumen as the oesophageal lumen and an open lumen as a respiration lumen, which opens out into a respiration chamber which can be sealed under the cover plate by the cuff. 
     
     
         2 . The larynx mask of  claim 1  wherein the cross-section of the respiration lumen is larger than the cross-section of the oesophageal lumen in the opening area of the insertion connection. 
     
     
         3 . The larynx mask of  claim 1 , wherein the cross-section of the respiration lumen is smaller than the cross-section of the oesophageal lumen in the opening area of the tube connecting connector. 
     
     
         4 . The larynx mask of  claim 1  wherein the separating and supporting wall of the larynx mask runs perpendicularly to the cover plate. 
     
     
         5 . The larynx mask of  claim 1  wherein at the proximal end of the larynx mask the separating and supporting well runs to the oesophageal outlet which is formed by an opening in the cover plate so that the oesophageal outlet extends above it over the cuff. 
     
     
         6 . The larynx mask of  claim 1  wherein the insertion section is limited by a projection narrowing the cross-section and serving as a stop for the insertion tube to be inserted. 
     
     
         7 . The larynx mask of  claim 1  wherein the respiration chamber is delimited by a circumferential adhesive or welding edge which runs from the cover plate to the cuff. 
     
     
         8 . The larynx mask of  claim 7  wherein the separating and supporting well extends from the cover plate to maximally down into the plane spanned by the circumferential adhesive or welding wall. 
     
     
         9 . The larynx mask of  claim 1  wherein the separating and supporting wall has a proximally closed, sack-like intermediate space for accommodating a reinforcing element.
