Plasma Treatment Device and Method for Plasma Treatment

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

This patent describes a plasma treatment device and method in which at least one electrode in the device is mounted so it can move (for example, by rotation). As the electrode moves, it generates plasma at varying locations within a supplied gas stream, allowing for larger surface areas to be treated more efficiently. The device is particularly suited for generating cold atmospheric pressure plasma and can be constructed in hand-held, compact shapes suitable for various surface treatments.

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

• Sterilization and disinfection of medical instruments, wounds, or surfaces
• Surface activation or preparation in manufacturing (e.g., improving adhesion in plastics or coatings)
• Cleaning and decontaminating sensitive electronic or optical components
• Cosmetic or dermatological treatments involving plasma (e.g., skin rejuvenation)
• Large-surface area plasma treatment in industrial processing lines
• Antimicrobial treatment of food packaging or containers

BenefitsContent extracted from patent full text and abstract with AI.

• Enables treatment of larger surface areas without needing to move the device itself, increasing efficiency
• Reduces required treatment time compared to fixed-electrode designs
• Enables uniform and consistent plasma generation across surfaces
• Compact and potentially hand-held design for ease of use
• Flexible electrode movement mechanisms (rotational, linear, etc.) allow for adaptation to various applications and shapes
• Cold plasma operation minimizes thermal damage to sensitive surfaces

Patent Abstract

A plasma treatment device having an electrode arrangement (3) for generating a plasma in a supplied gas stream. The electrode arrangement has at least one movably mounted electrode. The plasma is preferably a cold atmospheric pressure plasma and can be generated so as to vary in location by means of movement of the at least one electrode.
