Devices that allow for rapid change out of endotracheal (ET) tubes and related methods

A tracheal tube device, comprising:

• a mouthpiece comprising an external port merging into an open internal channel sized and configured to allow an endotracheal tube to extend therethrough into a trachea of a subject, the external port having a perimeter, wherein the mouthpiece also comprises at least one short tube with a cavity residing above the external port;
• and
• a handle holding a cutting member and comprising at least one interlock member that interlocks to the mouthpiece,
• wherein the handle comprises first and second cooperating handle members that can open and close relative to each other and that hold a metallic member defining the cutting member therebetween, wherein the metallic member has a longitudinally extending substantially cylindrical segment held by first and second spaced apart planar segments, wherein the first planar segment is attached to the first handle member and the second planar segment is attached to the second handle member, and wherein in an operative configuration, the first and second handle members extend laterally away from the mouthpiece while the at least one interlock member resides in the short tube with the first and second planar segments being adjacent and parallel to each other with the cylindrical segment held over the external port of the mouthpiece.
