Abstract: A larynx mask is provided that comprises a dorsal cover plate with an inflatable cuff integrally formed thereon and a tube connecting connector having an 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. These two lumens are separated from each other by a separating and supporting, wall. The separating and supporting wall extends from the insertion section to the tip of the larynx mask. While the esophageal lumen opens into an esophageal outlet at the proximal end of the mask, the respiration lumen opens in the ventral direction and is closed in the proximal direction close to the tip of the mask. Such a larynx mask is produced in one piece by way of injection of molding and is reinforced by the separating or supporting wall to prevent kinking.
Abstract: Thus far, it has not been possible to produce laryngeal masks having a supraglottic tube as a one-piece unit. If the supraglottic tube (2) is provided with three lumens (4, 5, 6), the center one (6) of which has no passage to the respiration space (10), a solution is proposed. What is proposed is that the center guide lumen is provided with a longitudinal slit (8) extending from the distal end (9) to the laryngeal mask head (3). A connecting web can be attached between two cores or sliders forming the lumens, generating the desired stability in order to maintain the pressing power tool state without deformation.
Abstract: Especially during emergencies, there is a need for laryngeal mask heads with a ventral respiration chamber (3) that has a cuff (4) which surrounds the respiration chamber and which can be adjusted in size without having to be inflated. To meet said need, the laryngeal mask head comprises non-pneumatic means (6, 7) to adjust the size in the medial-lateral direction and ventral-dorsal direction (12), which is preferably implemented by open, resilient grooves (10, 20) extending in the same direction as the cuff (4).
Abstract: A larynx mask (1) includes a cover plate (12) having a peripheral cull (13) adjoining thereon and is provided with a tube insertion connector (11) at the proximal end, while the tip (4) has a special design at the distal end. The cover plate 12 ends in the region of the tip on the cuff, or even before that, and the esophageal passage (18) runs as an open channel (20) over a constricted region (13?) of the cuff (13). Said channel preferably includes a widening (22) and is delimited on both sides by reinforcement means (21), which are preferably formed by reinforcing walls (21?) or additionally as reinforcing ribs (21?). Said design of the lead-through of the esophageal passage results in a considerable reinforcement of the proximal tip of the larynx mask and therefore counteracts possible kinking of the tip (4).
