Abstract:
1. An apparatus for forming NO-containing gas flow to treat a biologic object, the apparatus comprising: a housing; at least two electrodes accommodated inside said housing so that an interelectrode area is provided between said electrodes to generate a direct current arc discharge, said electrodes being electrically insulated from each other; voltage applying means for applying a voltage to said electrodes to generate and maintain the direct current arc discharge between the electrodes, wherein a positive potential is applied to one of the electrodes being an anode, and a negative potential is applied to another electrode being a cathode; floating potential electrode disposed in said interelectrode area, electrically insulated from said anode and said cathode, wherein said floating potential electrode has a through hole coaxial with the cathode to provide a steady discharge burning; an inlet channel communicating with said interelectrode area for injecting source gas into the interelectrode area, said source gas containing at least oxygen and nitrogen; an NO-containing gas flow outlet channel for withdrawing NO-containing gas flow from the interelectrode area and directing said NO-containing gas flow to treat the biologic object, said NO-containing gas flow being formed from said source gas under the effect of said direct current arc discharge, and cooling means for cooling said outlet channel and at least one of said anode and cathode.
