The present invention relates to the field of plasma medical devices, and in particular provides hot plasma disease treatment systemS and methods of use thereof.
Plasma is a fourth state aside from solid, liquid, and gas, and 99% of the matter in the universe is in the plasma state. Plasma is usually divided into equilibrium plasma, also called hot plasma (with the electron temperature equal to the heavy particle temperature), and non-equilibrium plasma, also called cold plasma (with the electron temperature greater than 10000 K, which is much higher than the heavy particle temperature close to room temperature).
Application of cold plasma in medical research has been a hot spot for scientists for the past 20 years. Encouraging effects have been achieved in dealing with bacteria and viruses on the skin surface and subcutaneous tumors. However, due to technical limitations, cold plasma has the following disadvantages:
An objective of the present invention is to provide hot plasma disease treatment systems and methods of use thereof, which can be used not only for sterilization of the surface of a living body and local treatment of wounds, but also for rehabilitation and treatment of diseases such as systemic viral diseases of a living body, diseases of deep viruses such as visceral viruses in a living body, and nervous system degenerative disease.
