ABSTRACT:
An electrode for laryngeal electromyography that is attachable to an insert device, endotracheal tune or other similar device that is also size adjustable by cutting to size. The attachable and size adjustable surface electrode of this invention consists of a flexible plate having an anterior and a posterior surface specifically for inserting in the human laryngopharynx adjacent to the cricothyroideus muscles (the vocal cords). An electrical conductive plate is mounted on the anterior surface to provide an electric contact with the cricothyroideus muscles. An insulated wire extends from the electrical conductive plate for monitoring or delivering electrical pulses to the cricothyroideus muscles. There are marked graduations parallel to a center line on the electrical conductive plate for cutting and sizing the flexible plate and electrical conductive plate to the size of the patient's laryngopharynx. There is an adhesive material on the posterior surface of the flexible plate for attachment of the attachable and size adjustable surface electrode for laryngeal electromyography to an endotracheal tube, insert device, postcricoid paddle or other such device.
