1. A mechanical mannequin apparatus for demonstrating medical management of human normal and abnormal airways comprising:

  • a head region having an adjustable jaw;

    an adjustable neck region located below and in communication with said head region;

    a chest region located below and in communication with said adjustable neck region;

    wherein said head region and said adjustable neck region further comprising an upper airway having (a) at least one nostril aperature, (b) a nasal cavity having a proximal end, a distal end and a middle section that is disposed between said proximal end and said distal end of said nasal cavity, and wherein said nostril aperature is located at said proximal end of said nasal cavity, (c) an oral cavity having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said oral cavity, said oral cavity located below said nasal cavity, (d) a mouth opening located at said proximal end of said oral cavity, said mouth opening having an opening size determined by the position of said adjustable jaw, (e) a pharynx tube member having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said pharynx tube member, wherein said proximal end of said pharynx tube member is located below and in communication with said distal end of said nasal cavity and wherein said distal end of said oral cavity is located at and in communication with said middle section of said pharynx tube member, and (f) a larynx tube member having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said larynx tube member, wherein said larynx tube member lies below said oral cavity and in front of said pharynx tube member and wherein said proximal end of said larynx tube member is located at and in communication with said distal end of said pharynx tube member;

    wherein said chest region further comprising a lower airway having (a) a trachea tube member having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said trachea tube member, wherein said proximal end of said trachea tube member is located below and in communication with said distal end of said larynx tube member, (b) at least one bronchus tube member having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said bronchus tube member, wherein said proximal end of said bronchus tube member is located below and in communication with said distal end of said trachea tube member, and (c) at least one inflatable lung sac structure having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said inflatable lung sac structure, wherein said proximal end of said inflatable lung sac structure is located below and in communication with said distal end of said bronchus tube member;

    an esophagus tube member having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said esophagus tube member, wherein said esophagus tube member is located behind said trachea tube member and wherein said proximal end of said esophagus tube member is located below and in communication with said distal end of said pharynx tube member;

    a stomach bag structure having a proximal end, a distal end and a middle section disposed between said proximal end and said distal end of said stomach bag structure, wherein said proximal end of said stomach bag structure is located below and in communication with said distal end of said esophagus tube member;

    jaw adjusting means for opening, closing and adjusting the movement and the position of said adjustable jaw for effecting the opening size of said mouth opening, wherein said jaw adjusting means is located in juxtaposition to and in communication with said head region;

    neck adjusting means for adjusting the movement and the position of said adjustable neck region and said head region, wherein said neck adjusting means is in juxtaposition to and in communication with a portion of said adjustable neck region and said head region; and

    at least one restrictor means attached to at least a portion of at least one of said nasal cavity, oral cavity, pharynx tube member, larynx tube member, trachea tube member, and bronchus tube member, and combinations thereof, for causing sealing engagement against and volume restriction of at least one of said nasal cavity, oral cavity, pharynx tube member, larynx tube member, trachea tube member, and bronchus tube member, and combinations thereof.
