Secondly, it is advantageous during treatment of the same patient as bacteria accumulated in the drive unit may - although originating from the same patient - cause the wound treatment to be prolonged due to inflammation. Thirdly, the reduced level of bacteria is advantageous for the supervising personnel who will be exposed to a reduced level of bacteria.
