Harmonic cold plasma device and associated methods
A method for generating atmospheric pressure cold plasma inside a hand-held unit discharges cold plasma with simultaneously different rf wavelengths and their harmonics. The unit includes an rf tuning network that is powered by a low-voltage power supply connected to a series of high-voltage coils and capacitors. The rf energy signal is transferred to a primary containment chamber and dispersed through an electrode plate network of various sizes and thicknesses to create multiple frequencies. Helium gas is introduced into the first primary containment chamber, where electron separation is initiated. The energized gas flows into a secondary magnetic compression chamber, where a balanced frequency network grid with capacitance creates the final electron separation, which is inverted magnetically and exits through an orifice with a nozzle. The cold plasma thus generated has been shown to be capable of accelerating a healing process in flesh wounds on animal laboratory specimens.
