Abstract: A cold plasma coagulator clots blood bleeding from tissue during surgical operation in an effective manner, by applying unipolar cold plasma to the blood. The cold plasma coagulator has a high frequency power supply, gas dynamic block and plasmotron. The power supply has a rectifier, capacitor storage and voltage inverter. The said plasmotron is assembled in a hermetically sealed case and in which resonance inductor and dielectric tube are located coaxially. One end of the dielectric tube is connected to the gas dynamic block, another end is positioned to eject plasma through output nozzle. A needle corona electrode is located along the axis of the dielectric electrode. The coils of the resonance inductor has a low voltage and high voltage section, the low voltage section of resonance coils being connected to output of the voltage inverter. One pin of the high voltage section is isolated and another one is connected to the needle corona electrode.

Abstract: The present invention relates to a plasma generator to apply cold plasma in the fields of medicine, biology, ecological recovery, activation, purification, special processing of gases, liquids and solid substances as well as other areas of technology and science. A plasma generator of the invention comprises: a power source; an electronic oscillator constructed on an amplifying (control) element which is connected to a low voltage input section; a resonance transformer having a low voltage input section and a high voltage output section; and, one pin of the high voltage output section of the resonance transformer which is connected to a discharge electrode. The present invention provides a universal plasma generator with decreased mass and dimensions which provides unipolar plasma for plasma therapy and activation of substantial media by virtue of the field.
