A battery powered handheld air plasma spray was designed, developed and successfully demonstrated. The power supply includes a battery, a dc HID ballast and a series LC matching circuit. This matching circuit is designed to maintain the performance of the HID ballast while driving arc discharges, which are rotated around the electrodes by the magnetic field of a ring magnet. The produced plasma is in a non-equilibrium state thus, the plasma effluent is low temperature (touchable) and yet carries abundant reactive atomic oxygen, which can rapidly activate blood coagulation processes and can effectively kill numerous microbes. This invention is for blood coagulation and sterilization applications. The device may be installed in vehicles and carried and operated in open fields without AC power sources. It may be used for bleeding control in a serious mishap to treat wounds without having to move the injured.
