The invention relates to a system for treating surfaces of bodies, in particular a vacuum dressing, comprising at least one attachment means (5a) for fluidic attachment of a negative-pressure generator for generating a negative pressure in a volume that can be positioned at the surface of a body, and at least one means for plasma generation (8, 8a, 15) with which the volume in which the negative pressure can be generated can be at least partially filled with plasma or a plasma-activated medium.

The invention relates to a device, to a system, and to a method for antimicrobial treatment during performance of operations in bodies, to a method for producing the device, and to a computer program. A device (11) is provided for antimicrobial treatment during performance of operations, in particular minimally invasive operations, in bodies. Said device comprises a main body (1) for partial introduction into a body and at least one plasma source (12) arranged in at least one portion of the main body (1).

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, preferably a collar, for treating areas of human or animal skin or mucous membrane with a cold atmospheric pressure plasma by creating a dielectrically hindered surface discharge, comprising at least one flexible insulating material (1), a flexible high-voltage electrode (2), a flexible dielectric (3), a flexible grounded electrode (4) and a gas supply (7), characterized in that the flexible high-voltage electrode (2) is embedded in the insulating elastomer (3), having the effect of a dielectric, and the grounded electrode (4) is applied to the elastomer s

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.

The invention relates to a device (10) for treating a liquid with a plasma, the device (10) having a high-voltage electrode (20) and a liquid-permeable ground electrode device (30). The ground electrode device (30) has a flat, conductive area (32) and a porous area (34) arranged on the flat, conductive area (32), the conductive area (32) being liquid-permeable along its area. A discharge space (40) is formed between the ground electrode device (30) and the high-voltage electrode (20).
