A plasma coating device for treating a wound comprises a plasma chamber having: one or more electrodes, a gas supply inlet, a plasma outlet exposed to ambient pressure, and an ignition system operatively connected to the electrodes for providing a non-thermal equilibrium plasma within the plasma chamber. An aerosol delivery system is operable to introduce a bioresorbable material as an aerosol into the plasma, to produce a coating on the wound surface.

The present application relates to a device for treating skin using non-thermal plasma. It comprises a housing having a skin interface electrode for application to skin during treatment, a generator for generating non-thermal plasma at the skin interface electrode; and an isolating element to isolate a region surrounding said skin interface electrode other than during treatment so that non-thermal plasma generated at the skin interface electrode within said region sterilises the skin interface electrode.

A method and apparatus for electro-hydrodynamic destruction of an aerosol. The method includes receiving air having large aerosols, greater than about 1 micron, and small aerosols, smaller than about 1 micron, and entraining the large aerosols and small aerosols within an airflow. The airflow is directed to an electric field, which causes the large aerosols to react with the electric field to accumulate an electric charge resulting in extraction of the large aerosols from the airflow. The airflow is also directed to a non-thermal plasma such that the small aerosols remain entrained in the airflow and are subject to electro-hydrodynamic (EHD) phenomena. The non-thermal plasma outputs at least one of radicals, excited species, and ionized atoms and molecules capable of reacting with the small aerosols to result in physical and/or chemical destruction of the small aerosols.

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.

An array of non-thermal plasma emitters is controlled to emit plasma based on application of an electric current at desired frequencies and a controlled power level. A power supply for an array controller includes a transformer that operates at the resonant frequency of the combined capacitance of the array and the cable connecting the array to the power supply. The power into the array is monitored by the controller and can be adjusted by the user. The controller monitors the phase relationship between the transformer primary winding voltage and the gate drive voltage, and adjusts the drive frequency to resonance. Alternatively the balanced driver is configured as an oscillator which drives the transformer at resonance by default. A signal from the transformer driver generates an interrupt to the controller for synchronizing current and voltage measurements for power control.

This invention relates to methods and systems for reducing the concentration of SOx and/or NOx in gas streams.

A method and device to apply a cold plasma to a substance at a treatment surface of a patient to cause electroporation of the substance into cells of the patient. The substance can be previously applied to the treatment surface. Alternatively, the substance can be placed in a foam-like material within a tip that passes the cold plasma from the cold plasma device to the treatment area. The tip can be a cannula device with an aperture at the distal end. The cannula device can also have apertures along a portion of the length of the cannula device.
