Abstract

See full text

A laryngeal mask assembly (10) includes an artificial airway tube (14) and an inflatable mask (26). The mask (26) is forced into the mouth (20) of a patient (12) to an operating position adjacent the larynx (21). A scoping instrument (22) is sent through the artificial airway tube (14) and the inflatable mask (26) to locate the vocal cords (23) and trachea (35). The artificial airway tube (14) and inflatable mask (26) are removed, keeping the scoping instrument (22) in a position within the trachea (35) whereafter the laryngeal mask assembly (10) is removed by peeling it off the scoping instrument (22) using the slit (34) creating by the overlapping edges (36, 38).
