Abstract
An apparatus and method for the relieving of sinus congestion by application of microcurrents to the facial areas of a human patient. The apparatus includes a carrying case adapted to be held by one hand of the patient, a power source, an oscillator connected to the power source and a voltage excursion generator. A current limiter limits the net current offset to microcurrent excursions. The apparatus further includes a probe connected to the circuitry for generating microcurrent excursions. The probe has a first electrode adapted to be placed in contact with the facial area of the patient for supplying microcurrents to the patient's sinus area, and a second electrode insulated from the first electrode. The second electrode has a conducting surface adapted to be engaged by the patient's other hand establishing an electrical circuit for microcurrent flowing through the nasal and sinus area. The apparatus further includes a sensor for sensing bodily impedance, and a visual indication that informs and directs the patient to move the probe from facial areas of high tissue impedance to facial areas of low tissue impedance.
