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 room (10), the invention provides a solution. The invention proposes that the center guide lumen is provided with a longitudinal slit (8) extending from the distal end (9) to the laryngeal mask head (3). Thus, a connecting web can be attached between the two cores or sliders forming the lumens, generating the desired stability in order to maintain the pressing power tool state without deformation.
Claims16
A laryngeal mask comprising a supraglottic tube for insertion of a laryngeal mask head over a larynx, wherein the supraglottic tube comprises:
- (a) a respiration lumen, which serves to supply respiration air and for instrumentation, (b) an esophageal lumen, which serves to provide esophageal access, and (c) a guide lumen that runs medially in between the respiration lumen and the esophageal lumen and is closed at a proximal end, wherein
- the supraglottic tube and the laryngeal mask head are manufactured by injection molding in one piece, and wherein a connecting slot, which connects the guide lumen and at least one of the respiration lumen and the esophageal lumen, runs over at least a portion of the length of the supraglottic tube from a distal end and runs between the at least one of the respiration lumen and the esophageal lumen and the guide lumen.
