Skin disorders are a common problem. Skin problems such as Atopic dermatitis caused by diabetes or varicose veins can cause patients years of suffering.
Scientists have developed a new medical technology solution known as 'PlasmaDerm' for treating wounds and skin disorders.
PlasmaDerm is a device that generates a non-thermal or 'cold' plasma directly on the skin at atmospheric pressure. The method involves placing the electrode of the device close to the skin, with the skin itself acting as the second electrode. A high voltage is then applied across the gap, and the resulting electric fields convert the area between the electrode and the skin into non-thermal plasma.
Plasma promotes wound healing when it is generated directly on the skin. Since cold plasma has not been used on human beings before, the top priority of the scientists was to evaluate the safety of the solution.
"We carried out a risk-benefit analysis to evaluate all the chemical and physical parameters and concluded that there is no reason to be concerned about using plasma on people," says Dr. Andreas Helmke, describing how Fraunhofer IST went about the process.
A clinical study conducted by Prof. Steffen Emmert at the Department of Dermatology, Venereology and Allergology at the University Medical Center Gottingen revealed an antiseptic effect and improved wound healing.
The method was developed jointly by Cinogy and the Department of Dermatology, Venereology and Allergology at the University Medical Center Gottingen and the Fraunhofer Institute for Surface Engineering.
