Estimating the term…
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.

An electrode arrangement for an antiseptic dielectric barrier discharge plasma treatment of an area on a skin surface, comprising:
The electrode arrangement as claimed in claim 1, wherein the ring-shaped contact surface is at an angle >20° in relation to the longitudinal axis.
The electrode arrangement as claimed in claim 1, wherein the dielectric includes air guiding regions on a side facing the skin surface when the dielectric lies on the skin surface.
The electrode arrangement as claimed in claim 3, wherein protruding lugs form the air guiding regions, wherein surfaces of the protruding lugs form a contact surface to contact the skin surface.
The electrode arrangement as claimed in claim 1, wherein the planar electrode is flexible.
The electrode arrangement as claimed in claim 12, wherein the entire ring-shaped contact surface is arranged at an acute angle of >20° and <90° relative to the longitudinal axis, and the ring-shaped contact surface faces towards the skin surface when the skin penetration piece is arranged to penetrate the skin surface.
The electrode arrangement as claimed in claim 1, wherein the electrode arrangement is configured to disinfect the skin surface as well as a skin penetration region, the skin penetration region including a channel through which the skin penetration piece penetrates the skin surface.
An electrode arrangement for an antiseptic dielectric barrier discharge plasma treatment of an area on a skin surface, comprising:
The electrode arrangement as claimed in claim 8, wherein the entire ring-shaped contact surface is arranged at an acute angle of >20° and <90° relative to the longitudinal axis, and the ring-shaped contact surface faces towards the skin surface when the skin penetration piece is arranged to penetrate the skin surface.
The electrode arrangement as claimed in claim 8, wherein the skin penetration piece is configured as a permanent catheter, a permanent infusion cannula, or an external fixator.
The electrode arrangement as claimed in claim 10, wherein a side of the dielectric arranged facing the skin surface comprises air guiding regions, and the air guiding regions are formed by protruding lugs having surfaces which provide interface with the skin surface when the dielectric contacts the skin surface.
The electrode arrangement as claimed in claim 8, wherein the electrode arrangement is configured to disinfect the skin surface as well as a skin penetration region, the skin penetration region including a channel through which the skin penetration piece penetrates the skin surface.
An electrode arrangement for an antiseptic dielectric barrier discharge plasma treatment of an area on a skin surface, comprising:
The electrode arrangement as claimed in claim 13, wherein the ring-shaped contact surface is configured to fasten to the skin penetration piece.
The electrode arrangement as claimed in claim 13, wherein the entire ring-shaped contact surface is arranged at an acute angle of >20° and <90° relative to the longitudinal axis.
The electrode arrangement as claimed in claim 13, wherein the skin penetration piece is configured as a permanent catheter, a permanent infusion cannula, or an external fixator.
The electrode arrangement as claimed in claim 13, wherein a side of the dielectric arranged facing the skin surface comprises air guiding regions, and the air guiding regions are formed by protruding lugs having surfaces which provide interface with the skin surface when the dielectric contacts the skin surface.
The electrode arrangement as claimed in claim 13, wherein the electrode arrangement is configured to disinfect the skin surface as well as a skin penetration region, the skin penetration region including a channel through which the skin penetration piece penetrates the skin surface.
The electrode arrangement as claimed in claim 1, wherein the planar electrode is flexible.
The electrode arrangement as claimed in claim 1, wherein the dielectric and the planar electrode have a radial slit formed therein and a partial circular construction, the radial slit providing mounting of the planar electrode with the dielectric to the skin penetrating piece
