Abstract

A laryngeal mask of the type used to facilitate lung ventilation and the insertion of endo- tracheal tubes or related medical instruments through a patient's laryngeal opening as used during general anesthesia, intensive care, or critical patient care. The mask includes an inflatable positioning shield formed to fit within a patient's oropharynx and seal around the circumference of the laryngeal opening, the shield having an inflatable annular toroid peripheral portion, a contoured rear portion, and a recessed front. The mask also includes a flexible respiratory tube having an proximal end lumen, a gently curved tubular body of sufficient size to permit passage of endo- tracheal tubes, and related medical instruments, and a distal end passing through and secured to the proximal edge of the annular toroid peripheral portion. The distal end of the tube terminates at a distal lumen within the recessed front of the inflatable positioning shield such that tubes and instruments passing through the flexible respiratory tube will be directed into the laryngeal opening.
