Tracheal intubation system including a laryngoscope

A stylet adapted for mounting an endotracheal tube, the stylet comprising:

• a shaft comprising a first segment and a second segment, wherein the first segment comprises a tip at a distal end of the shaft;
• an articulating portion arranged between the first segment and the second segment that allows the first segment to move relative to the second segment;
• a control mechanism configured to control movement of the first segment relative to the second segment, the control mechanism comprising a lever, wherein the lever is pivotable in a first direction and a second direction, and further wherein when the lever is pivoted in the first direction, the tip pivots in the first direction;
• wherein the first direction is away from a longitudinal axis of the shaft and wherein the second direction is towards the longitudinal axis of the shaft;
• and wherein the stylet is sized to allow the endotracheal tube to be passed over it from end to end.

A stylet for mounting an endotracheal tube, the stylet comprising:

• a shaft comprising a first segment and a second segment, wherein the first segment of the shaft comprises a distal end comprising a tip;
• an articulating portion arranged between the first segment and the second segment that allows the first segment to move relative to the second segment;
• a plurality of depth assessment bands located on the shaft, each depth assessment band visually distinct from an adjacent depth assessment band, a first depth assessment band located near the distal end, and having a first visual representation, wherein when the first depth assessment band is positioned adjacent the vocal cords of a patient, the first depth assessment band indicates that the tip has not been inserted to an appropriate depth;
• a second depth assessment band located adjacent the first depth assessment band, and having a second visual representation, wherein when the second depth assessment band is positioned adjacent the vocal cords of the patient, the second depth assessment band indicates that the tip has been inserted to an appropriate depth;
• and
• a third depth assessment band located near the distal end, and having a third visual representation, wherein when the third depth assessment band is positioned adjacent the vocal cords of a patient, the third depth assessment band indicates that the tip has not been inserted to an appropriate depth;
• and wherein the stylet is sized to allow the endotracheal tube to be passed over it from end to end.
