The generated oxidants are directed to intersect with the exhaust stream to minimize the generation of unwanted byproducts. The tube cells are further shaped and arranged in tube cell arrays to alter the flow dynamics of the exhaust stream and the oxidant or radical streams, including mixing of the streams.

This invention discloses a cold plasma therapy device with enhanced safety. The plasma therapy device comprises a dielectric barrier made of a material with high dielectric constant (i.e., relative permittivity). Hence the thickness of the dielectric barrier can be increased to produce similar plasma intensity in comparison to a dielectric barrier with a low dielectric constant. The increased thickness enhances the mechanical durability of the dielectric barrier. When the thickness of the dielectric barrier is larger than the maximum discharge gap of the ambient air (or the supplied gas medium) under the voltage applied, no arc discharge will be produced even when there is a crack across the thickness of the dielectric barrier. This minimizes the risk of subject tissue damage from possible electric shocks.

The present disclosure relates to a plasma device for alleviation of various skin troubles or for skin care, and provides a remote type plasma device wherein a plasma spray device is separated from the body thereof and is connected to a controller in the body. Plasma is produced under atmospheric pressure at room temperature. The plasma device of the present disclosure includes a dielectric barrier and thus can maintain stable glow discharge. Atmospheric plasma is unexceptionally sprayed through a ground electrode, and thus does not electrically irritate the skin at all.
