Title: MEDICAL PLASMA-GENERATING DEVICE AND PLASMA IRRADIATION METHOD
Abstract:
This plasma irradiation device 10 is provided with a plasma ejection device 12 that ejects plasma, and an inert gas ejection device 16 that ejects inert gas. The plasma ejection device ejects plasma from inside a cylinder part 30. The inert gas ejection device ejects inert gas from between the inner peripheral surface of a cylinder part 76 and the outer peripheral surface of the cylinder part 30. Therefore, the plasma is ejected so as to pass through the inside of the inert gas ejected in a cylindrical shape. Specifically, the inert gas is ejected so as to cover the outer periphery of the ejected plasma. Therefore, the ejected plasma is shielded by the inert gas, and the plasma can be irradiated on an affected part without being exposed to air. It is thereby possible to irradiate plasma of a suitable concentration on the affected part, making it possible to perform effective treatment.
