PLASMA TREATMENT DEVICE AND METHOD FOR ADJUSTING THE SIZE OF THE CONTACT SURFACE OF THE PLASMA TREATMENT DEVICE TO THE DIMENSIONS OF THE SURFACE TO BE TREATED Russian patent published in 2023 - IPC H05H1/24 A61L2/14 A61N1/44 

FIELD: plasma technology.

SUBSTANCE: in a plasma treatment device for conducting a plasma dielectric barrier discharge on a surface to be treated, containing a flat electrode block (4) having a processing side and a control block (11), which supplies at least one electrode (19) of the electrode block (4) with a high-voltage an alternating potential for generating the power necessary to produce a plasma between said at least one electrode (19) and the counter electrode forming the reference potential. At least one electrode (19) receiving said high-voltage alternating potential is shielded by a flat dielectric (7) at least from the processing side. The flat electrode block is made with the possibility of reducing the dimensions of its contact surface on the surface to be treated to adjust to the dimensions of the surface to be treated. Correction of the contact surface of the flat electrode block (4) does not cause problems due to the fact that the control block (11) contains a device (14) for determining the size of the contact surface to be corrected and a control device for setting the power output to at least one specified electrode (19) in depending on the size of the contact surface.

EFFECT: increased efficiency of plasma treatment.
