DEVICE AND METHOD FOR DRY-CLEANING, ACTIVATING, COATING, MODIFYING, AND BIOLOGICALLY DECONTAMINATING THE INNER WALLS OF HOSES, PIPES, AND OTHER HOLLOW BODIES

摘要

The invention relates to a device and method for uniformly producing a physical plasma in long and simultaneously narrow tubular cavities or flexible or rigid, dielectric hoses, pipes, or other hollow bodies (referred to as hoses below) in the low or normal pressure range in order to dry-clean, activate, coat, modify, and biologically decontaminate (purify, disinfect, sterilize) the inner walls of said hoses, and for therapeutic applications, by means of barrier discharge. The device comprises a high-voltage supply and a gas supply, at least one electrically conductive, grounded electrode, and at least one electrically conductive high-voltage electrode in the wall of the hose, wherein the electrodes extend helically along the axis of the hose or extend in parallel in the axial direction, or the electrodes are introduced together with non-conducting fibers as a mesh.
