Endotracheal Tube for Nerve Monitoring

摘要

An endotracheal tube for nerve monitoring including one or more ground, reference, or laryngeal-monitoring electrode wires that run in a direction parallel to the central axis of the tube, each such electrode wire having an insulated first wire portion and an uninsulated second wire portion, and further including one or more ground, reference, or hypoglossal-monitoring electrode wires wrapped around the outer surface of the endotracheal tube in a helical, circular, or interposed pattern

主权项

1. A nerve monitoring device comprising:
an endotracheal tube formed from a flexible, non-electrically conducting material and having a distal end, a proximal end, a central axis, and an outer surface; at least one ground, reference, or laryngeal-monitoring electrode wire including electrically conducting material running in a direction parallel to the central axis at a location between the distal end and the proximal end of the endotracheal tube; the at least one ground, reference, or laryngeal-monitoring electrode wire having an electrically insulated first wire portion located between the distal end and proximal end of the endotracheal tube and an electrically uninsulated second wire portion located on the outer surface of the endotracheal tube between the first wire portion and the distal end of the endotracheal tube; the second wire portion comprising means for contacting the laryngeal muscles when the endotracheal tube is placed in the trachea for ventilation; and at least one ground, reference, or hypoglossal-monitoring electrode wire including electrically conducting material wrapped around the outer surface of the endotracheal tube in a helical or circular pattern.
