Device and Method for Generating an Electrical Discharge in Hollow Bodies

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention relates to a device and method for generating a physical plasma (an electrically charged gas) inside long, narrow, flexible or rigid dielectric tubes and hollow bodies. The core innovation is to embed electrically conductive electrodes directly into the tube walls, eliminating the need for extra internal or external electrodes. By applying a high voltage between these integrated electrodes, a uniform plasma is generated inside the tube, allowing for cleaning, activation, coating, modification, and biological decontamination of the tube's internal surfaces or the fluid inside.

Use CasesContent extracted from patent full text and abstract with AI.

• Sterilization and decontamination of medical device channels such as endoscope lumens.
• Internal cleaning, activation, or surface coating of tubes, hoses, or pipes in the food, medical, or pharmaceutical industries.
• Modification or functionalization of the inner surfaces of catheters or dialysis tubing.
• Generation of therapeutic plasma for medical treatments via endoscopic or minimally invasive instruments.
• Treatment and decontamination of process fluids or gases as they flow through narrow conduits.
• Uniform plasma-based surface modifications in industrial hoses or piping without dismantling the installation.

BenefitsContent extracted from patent full text and abstract with AI.

• Allows homogeneous plasma treatment along the entire length of long, narrow tubes, even in complex, assembled products.
• No need to use or insert special electrodes inside or outside the tube after manufacture, simplifying the process and reducing the risk of damaging sensitive device parts.
• Maintains or even improves the flexibility and mechanical integrity of the tubes, crucial for medical devices like endoscopes.
• Enables plasma generation at atmospheric pressure and with a variety of gases or process media, not limited to expensive noble gases.
• Facilitates plasma generation even with wet or liquid-filled tubes and for diverse applications like coating, cleaning, or sterilization.
• Straightforward manufacturing integration and retrofitting possible, reducing costs and fitting seamlessly into existing workflows.
• Improves safety by reducing the need for chemical disinfectants or aggressive cleaning agents.
