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.

Electrode arrangement for plasma treatment and device for producing a transcutaneous connection

A device for treating a surface with a dielectric harrier plasma, wherein the surface functions as a counterelectrode, has an electrically insulating housing and a housing head. A rotatable electrode connected to a high-voltage feed line is shielded by a dielectric and protrudes out of the housing head. The configuration has fundamentally unrestricted movement of the electrode over the surface to be treated in that the electrode has rotary bearing elements which are arranged in a center axis and a rotation axis is at an angle to the center axis.

Device for treating a surface with a dielectric barrier plasma

The invention relates to an electrode array for a dielectrically impeded plasma treatment of a surface of an electrically conductive body used as a counter electrode, comprising a flexible planar electrode () and a dielectric () of a planar flexible material, which by way of a layer () preventing a direct current flow shields the electrode () from the surface to be treated. By way of a structure having projections, the dielectric () can rest upon the surface to be treated, wherein air spaces for forming the plasma are formed in between the projections. The producibility in particular is improved in that the structure is a lattice structure () of adjoining walls () that limit a plurality of chambers () forming the air spaces, and in that the chambers () have a bottom-side closure through the layer () of the dielectric () preventing the direct current flow and have a face that is open to the surface to be treated, the contact surface of which face consists of end edges () of the walls () of the lattice structure () on the surface to be treated.

The invention relates to a treatment device for a surface to be treated using a dialectically impeded plasma, comprising a housing () which has an end wall (') and comprising an electrode () which is shielded from the surface to be treated by a dielectricum () that forms at least one part of the end wall (&#x2032;) and which can be connected to a high-voltage generator (). The end wall (&#x2032;) has at least one spacer (&#x2032;) by means of which at least one gas chamber is formed when the at least one spacer (&#x2032;) rests against the surface to be treated, and the dialectically impeded plasma is formed in the gas chamber for the treatment process. The treatment device simultaneously allows a treatment using the dialectically impeded plasma and the metered supply of a treatment agent in that a storage chamber (&#x2032;) which can be filled with a treatment agent is arranged on the end wall (&#x2032;) face facing away from the surface to be treated; the end wall (&#x2032;) has passage openings (&#x2032;); and the volume of the storage chamber (&#x2032;) can be reduced such that the treatment agent reaches the region of the surface to be treated through the passage openings (&#x2032;) when the volume is reduced.

An electrode arrangement for forming a dielectric barrier plasma discharge between a flat surface () of the electrode arrangement and a surface to be treated which functions as a counter surface and on which a fluid can collect, comprising a flat electrode () which can be connected to a high-voltage source by means of a connector and which is completely embedded in a flat dielectric (), except for the connector for the high-voltage source, wherein the dielectric () forms an upper surface () and a lower surface () which appears as a flat surface to the surface to be treated, enables the drainage or supply of a fluid by means of a simple design. The flat electrode () has through openings () distributed across the surface thereof, and the dielectric () is provided with through openings () which extend from the lower surface () to the upper surface () and which align with the through openings () of the electrode () and which have smaller dimensions than the through openings () of the electrode (), so that the dielectric () is also completely covered in the region of the through openings () of the electrode ().

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.

In order to treat human or animal hair fixedly arranged on a sopport, hair is divided into strands. The divided strands are subjected to a dielectric plasma treatment by drawing an apparatus connected to a high voltage source () through the strands. The apparatus can be in the form of tongs or have a comb-like structure.
