ELECTRODE ARRANGEMENT FOR PLASMA TREATMENT AND DEVICE FOR PRODUCING A TRANSCUTANEOUS CONNECTION

摘要

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.

主权项

1. An electrode arrangement for an antiseptic dielectric barrier discharge plasma treatment of a wound area on a skin surface, comprising:
a planar electrode; a dielectric embodied as a planar material, wherein the planar electrode is fastened to the dielectric in such a way that a layer of the dielectric shields the electrode from the skin surface; a skin penetration piece providing skin penetration and having a longitudinal axis; a ring-shaped contact surface that is formed by the dielectric and is provided for fastening to the skin penetration piece; wherein the electrode arrangement surrounds the skin penetration piece and the contact surface is at an angle >20° in relation to the longitudinal axis.
