Disclosed is a device (1) for biologically decontaminating percutaneous access points or the stomata of patients, by means of a plasma generator (4) for generating a decontaminating plasma adjacently to a treatment surface (3) of the plasma generator (4). In order to at least partially surround a percutaneous access point or stomata, the treatment surface (3) is curved to be adaptable and can be laid against the percutaneous access point or stomata.

The invention relates to a device for the treatment of free-form areas and zones of human or animal skin areas or plant surfaces by means of cold atmospheric-pressure plasma. The core of the device is a specific, preferably gas-permeable, electrode arrangement for generating a dielectrically impeded surface discharge where the earthed electrode is composed of electrically conductive textile material and the high-voltage electrode consists of a thin wire or electrically conductive thread which is sheathed with an insulting layer which has to meet specific requirements.
