HEALING EFFECT OF THE G-NO THERAPY

When using the G-NO plasma® device, the therapeutic effect is ensured by the delivery of a gas stream to biological tissues at different temperatures (from 4,000°C to room temperature) but with the same content of nitric oxide (NO).   This is achieved by supplying atmospheric air through the working part of the device – the manipulator.

 
 
From a technical point of view, all of the manipulators of the G-NO plasma® device are constant current plasma generators, manufactured according to the linear three-electrode scheme.
 
Schematic design of the universal generator part of the manipulator:
 

 

 

When the manipulator is connected to a constant and stabilized current, a burning electric arc between the cathode and the electrode, and geometrically stabilized by the inter-electrode insert channel is formed.

Atmospheric air is fed into the manipulator by a built-in micro-processor, goes through the electric arc, heats up, goes to the plasma state, and then passes the anode opening to exit the generator part. The geometrical parameters of the generator channel part, and connecting and cooling properties are selected for the electric arc to ensure that the temperature inside the arc is optimal for forming nitric oxide.

 

 

Application of the unified generator part in all manipulators manipulators allows us to obtain flows with the same concentration of nitric oxide content, as shown in Fig. 4. The range of obtained NO concentrations is extremely wide, from 2,500 ppm to zero. This allows the doctor to select the parameters they consider to be the most appropriate. An analysis of the dependence of the nitric oxide content on the gas flow axis from temperature shows that G-NO plasma® provides the user with numerous combinations of thermal and physical and biochemical effects on biological tissues and objects.

The therapy is carried out by two types of manipulators:

 

 

COAGULATION

The coagulation of surface wounds is carried out by delivering a high-temperature air plasma flow (hereinafter “APF”) directly to the surface of the wound. The flow temperature at the contact area should not be less than 2,000°C, thus the distance from the manipulator outlet in the application area must be less than 25mm.

DESTRUCTION

When treating live tissues with the concentrated and narrowly-directed APF of the destructor, the charcoal layer of tissue heats up to ~ 800°C and starts to break down into small particles - to sublimate while the high-pressure flow carries (blows) ZVT decay products from the treatment area

 

 

 

In the case of the manipulator - coagulator and destructor – the heated air-plasma flow (APF) continuously flows directly into the surrounding area in the form of a brightly illuminated flame.
Nitric oxide is stabilised when the outflow into the surrounding cold air is inhibited.

COAGULATION a DESTRUCTION differ from each other only in the diameter of the anode outlet channel – 1.2 mm and 0.7 mm. This achieves the difference in the air-plasma flow speed – up to 200m/sec for the coagulator and up to 600m/sec for the destructor. The APF temperature after exiting to the surrounding area at the exit channel cut reaches 4,000°C, which is sufficient to achieve the surgical effect (coagulation and destruction).

 
In some cases, e.g. in minor surgery, in which there is no intense bleeding, it is not necessary to deliver such a hot flow to the tissues. Thus, the gas temperature must be lowered, but not at the expense of the nitric oxide content therein.
 
G-NO plasma® device achieves this goal through additional cooling of the flow from the generator block, which makes it possible, on the one hand, to decrease the flow temperature up to the ambient temperature, and on the other hand – “to freeze” the nitric oxide molecules formed in the electric arc of the generator block.
