Abstract: A device for treating a surface with a dielectric barrier plasma, wherein the surface functions as a return electrode, having a housing (1), in which a high-voltage feed line, an electrode (8) which is connected to the high-voltage feed line, and a dielectric (9), which screens the electrode (8) with respect to the surface, are located, permits the plasma treatment of highly curved surfaces and of relatively large surface areas by virtue of the fact that the electrode (8) has the shape of a circle which is mounted in the housing (1) so as to be rotatable at least to a limited degree, and projects with a spherical section from an end-side opening (5) in the housing (1), and in that the electrode (8) is coated with the dielectric (9) in such a way that its spherical section projecting out of the housing (1) is covered by the dielectric (9) in every possible rotational position.

Abstract: An electrode arrangement for forming a dielectrically impeded plasma between an active surface of a flexible, planar electrode that can be connected to a high voltage source has a planar, flexible dielectric that forms the active surface which is connected to the planar electrode to form an electrode element where the electrode is completely covered towards to surface to be treated. The electrode arrangement is adaptable to irregular surfaces using a contact with surface elasticity for pressing onto the rear face of the electrode element facing away from the surface such that the electrode element by local deformation is automatically adapted to the irregularities.

Abstract: A transcutaneous connection between an exterior and an interior of a human or animal body includes a cylindrical skin penetration piece which provides a passage through the skin and has a longitudinal axis that determines the direction of passage through the skin. Wound-healing action and reliable disinfection are effected using an annular flat electrode arrangement, which has a contact surface at an angle to the longitudinal axis, can be fastened to the skin penetration piece. The electrode arrangement includes a flat electrode and a flat dielectric shielding the electrode relative to the surface of the skin, and is designed as a counter-electrode to generate a dielectric barrier plasma between the dielectric and the surface of the skin.
