Abstract
An apparatus for monitoring EMG signals of a patient's laryngeal muscles includes an endotracheal tube having an exterior surface, and a tube coating applied to the exterior surface via spraying of a homogeneous solution onto the endotracheal tube or immersion of the endotracheal tube in the homogeneous solution. A conductive electrode is formed on the tube coating. The conductive electrode is configured to receive the EMG signals from the laryngeal muscles.
Claims20
An apparatus for monitoring EMG signals of a patient's laryngeal muscles, comprising:
- an endotracheal tube having an exterior surface;
- a tube coating applied to the exterior surface via spraying of a homogeneous solution onto the endotracheal tube or immersion of the endotracheal tube in the homogeneous solution;
- and
- a conductive electrode formed on the tube coating that has been applied to the exterior surface, the conductive electrode configured to receive the EMG signals from the laryngeal muscles.
A method of monitoring EMG signals of a patient's laryngeal muscles, comprising:
- providing an endotracheal tube having a tube coating applied to an exterior surface of the endotracheal tube via spraying of a homogeneous solution onto the endotracheal tube or immersion of the endotracheal tube in the homogeneous solution, and having a conductive electrode formed on the tube coating that has been applied to the exterior surface;
- sensing the EMG signals from the laryngeal muscles with the conductive electrode;
- and
- outputting the EMG signals sensed by the conductive electrode to a processing apparatus.
A method of applying an electrode to an endotracheal tube, comprising:
- dissolving a PVC solute in a mixture of solvents to form a homogeneous solution;
- spraying the homogeneous solution in an aerosol form on an outer surface of the endotracheal tube to form a tube coating;
- and
- printing a conductive electrode on the tube coating.
