US Patent 11672979 Device to induce electrical muscle relaxation for airway management

A system to induce electrical muscle relaxation for airway management. The illustrative system includes a power control system targeted to relax muscles associated with an airway channel, and more particularly, to assist in human intubation by placement of an endotracheal tube within the trachea of a patient, mask ventilation, and/or resolution of laryngospasm. The relaxation of the muscles is achieved through external stimulation of nerves through the skin by an output electrical current pattern applied by the power control system. The illustrative system is configured to independently regulate an output current frequency and an output current amplitude of the output electrical current pattern.
