apparatus and method for monitoring electromyographic (emg) signals from patient's larynx muscles

摘要

An apparatus for monitoring EMG signals of a patient's laryngeal muscles including an endotracheal tube having an exterior surface. Conductive ink electrodes are formed on the exterior surface of the endotracheal tube. The conductive ink electrodes are configured to receive the EMG signals from the laryngeal muscles when the endotracheal tube is placed in a trachea of the patient. At least on conductor is coupled to the conductive ink electrodes and is configured to carry the EMG signals receive by the conductive ink electrodes to a processing apparatus.
