Atmospheric plasma source, particularly for use in medicinal bioapplications

摘要

The atmospheric plasma source, particularly for use in medicinal bioapplications according to the present invention comprises an alternating high voltage source (5) and a hollow insulation body (1) with an inlet of processing gas opening into the inside thereof. In the interior of said hollow body (1) there is arranged an internal excitation electrode (2) that is connected to the alternating high voltage source (5). In the interior of the insulation body (1) there is arranged a sandwich structure formed by layers of porous material and consisting of the excitation electrode (2), an electrically non-conducting porous membrane (3) and an external grounding electrode (4), wherein all the components are arranged one above the other. The porous membrane (3) is made of elastic material of substantially constant thickness ranging within 1 to 200 microns with a maximum deviation of 15 %, and which exhibits temperature stability up to 300 degC with the pore size forming microchannels with diameter in the range of 10 nm to 100 microns.
