Abstract
A laryngeal mask () comprising an air-way tube () and a mask portion () with an inflatable cuff () which is arranged around the airway tube () at the distal end thereof. A gastric tube () which extends at least partially along the outer surface of the airway tube (), penetrates through the wall of said inflatable cuff () at a first location, extends through said inflatable cuff (), and ends in a connection to an opening () in the wall of the cuff at a second location at the tip part of the laryngeal mask, so as to provide a passage through said circumferential cuff. With respect to a central mirror symmetry plane said gastric tube extends along the outer surface of the airway tube () in an asymmetrical manner, through said inflatable cuff () at the first location arranged asymmetrically with respect to said central plane, through said inflatable cuff (), and ends in the connection to the wall of the cuff () at the second location at the tip part.
