P-Array - conceptual design of a plasma jet array for clinical and ambulatory use based on the kINPen® MED

The joint research project "P-Array" aims at the upscaling of the intensively researched plasma jet technology as well as an increase in mobility by means of an accumulator. For this purpose, the described project receives financial support from the European Union via the European Regional Development Fund and the state of Mecklenburg-Western Pomerania (TBI-V-1-361-VBW-124).

The plasma jet array must both ensure efficacy and meet current and future regulatory requirements. At INP and the Kompetenzzentrum Diabetes Karlsburg (KDK), based on years of preliminary work, a functional model of the scaled-up plasma jet technology is being researched in compliance with prescribed safety parameters and its efficacy is being demonstrated. In parallel, neoplas med GmbH is developing a device concept including an accumulator. Both fields of work will then be combined into one device, including ergonomic considerations. In the course of this, final safety-related questions will also be answered. The resulting device will pave the way for a new medical device with accumulator and large-area treatment.

Motivation

Patients with wound healing disorders sometimes develop large-area chronic wounds that can impose significant restrictions on their daily lives. There is still no established therapeutic approach for this problem. With the help of plasma medicine, the treatment of non-healing up to out of treatment wounds with cold atmospheric pressure plasmas, a specific therapy for this problem shall be developed. In particular, the practical question of selective treatment for local disturbances of wound healing and large-scale treatment of the entire wound arises. Medically approved devices based on the plasma jet are so far limited to the kINPen® MED.
