In addition to the well-known states of matter – solid, liquid, and gas – there is also a fourth state called plasma. Plasma is an electrically conductive, ionized gas that might be familiar from neon lights or such natural phenomena as the Northern Lights.

In medicine, a special form known as cold plasma is used. It can be applied directly to wounds while remaining at approximately body temperature. This makes the treatment gentle and comfortable for patients.

At the same time, cold plasma reduces harmful microorganisms in the wound without damaging healthy tissue. It also improves blood circulation and supports the body's natural wound-healing processes. Cold plasma can be used as an adjunct to standard wound care for chronic, complex, or infected wounds – for example, diabetic foot ulcers, venous leg ulcers, or pressure ulcers. Whether this treatment is appropriate is determined by the responsible healthcare professional. The underlying cause of the impaired wound healing must continue to be treated medically.

The innovative patch enables uniform treatment across the entire wound surface without painful direct contact. The system has been scientifically evaluated, is CE marked, and is already in use in numerous hospitals.
