Device for electrotherapeutical treatment of tension headaches

摘要

The device has an electric circuit supplying low voltage electric pulses to contact electrodes (11, 12). An electrode support allows excitation of afferent paths of supratrochlear and supraorbital nerves of an ophthalmic branch of a trig eminal nerve independently from a subject i.e. patient. The circuit includes a programmable signal generator for generating pulses with a duration between 150-450 microseconds, with a maximum increase in intensity of 0 to 20 milliamperes at a rate less than or equal to 40 microamperes per second and with a step up in intensity not exceeding 50 microamperes. An independent claim is also included for a method for treating headaches.
