The proposed invention relates to an electromedical device that produces a cold plasma at atmospheric pressure for use in blood clotting and the treatment of ulcers and other skin injuries in human and animal patients. The main claims relate to the use of gas pre-treated by means of a cooling and dehumidification, together with a system of plasma expansion chambers in the outlet channel of same. As a result of these innovations, the plasma produced using the invention has a lower temperature than those in the prior art, preserving greater effectiveness both in blood clotting and in the disinfection and treatment of skin injuries, without causing any damage to the patient's healthy tissue. The device can be used in the treatment of human and animal patients to considerably accelerate blood clotting without damage to healthy tissue, during clinical and surgical treatments. I can also be used to treat ulcers and other skin injuries, owing to its disinfection properties, without damaging healthy tissue.

A method for generating atmospheric pressure cold plasma inside a hand-held unit discharges cold plasma with simultaneously different rf wavelengths and their harmonics. The unit includes an rf tuning network that is powered by a low-voltage power supply connected to a series of high-voltage coils and capacitors. The rf energy signal is transferred to a primary containment chamber and dispersed through an electrode plate network of various sizes and thicknesses to create multiple frequencies. Helium gas is introduced into the first primary containment chamber, where electron separation is initiated. The energized gas flows into a secondary magnetic compression chamber, where a balanced frequency network grid with capacitance creates the final electron separation, which is inverted magnetically and exits through an orifice with a nozzle. The cold plasma thus generated has been shown to be capable of accelerating a healing process in flesh wounds on animal laboratory specimens.

Atmospheric-pressure plasma generation device 10 of the present invention includes heat sinks 27 and 28. Flow paths are formed in the heat sinks, and cooling gas flows in the flow paths, thereby cooling lower housing 20 in which a reaction chamber is formed. Here, the gas used for cooling is warmed by the heat of the lower housing. The warmed gas is supplied into heated gas supply device 14 and heated by heater 112. The heated gas flows in lower cover 22 and is emitted together with plasma gas from lower cover 22 toward a processing object. Consequently, it is possible to perform cooling of the lower housing heated by electric discharge and perform heating of the processing object, and it is possible to reduce energy required for heating gas.
