There is new hope for patients with chronic, poorly healing wounds: cold plasma combats dreaded antibiotic-resistant hospital pathogens effectively and stimulates the body’s self-healing powers. Cold plasma forms, for example, when a gas passes through strong electric fields – the electrons are dissociated from the molecules, and the gas becomes electrically conductive and glows blue. Among other things, plasma emits ions, UV radiation and radicals – a mixture of active species. We have developed a silicone-based wound dressing (PlasmaPatch) that creates this high-energy gas directly on damaged skin. The system components are: an HV-generator unit (PlasmaCube), a disposable PlasmaPatch and a plug-cable-plug system to connect them. One PlasmaPatch treatment takes less than three minutes. Handling is simple and treatment can easily be integrated into the daily regimen of changing wound dressings (for both in-patients and out-patients).
