Modular Plasma Jet Treatment System

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

The patent describes a modular plasma jet treatment system designed for medical and therapeutic use, particularly for oral applications like tooth treatment. The system consists of a high-voltage module and interchangeable plasma jet applicators, which can be easily connected and disconnected. These applicators generate one or multiple plasma jets by using a controlled gas flow within a cavity, providing flexibility in treating various surface areas. The modular design allows applicators of different shapes and outlet patterns to be swapped as needed, enabling efficient and targeted plasma treatments.

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

• Medical treatments on skin, gums, or teeth, such as sterilization, wound healing, and dental therapies.
• Oral care procedures requiring targeted and localized plasma jets for hard-to-reach regions of the mouth.
• Sterilization of biological material and medical instruments using plasma treatment.
• Therapeutic treatments involving plasma to accelerate tissue regeneration or control infections.
• Surface modification and cleaning in laboratories or small manufacturing settings.

BenefitsContent extracted from patent full text and abstract with AI.

• Highly modular and customizable: plasma jet applicators of varying geometries and jet counts can be swapped, enhancing adaptability for different treatments.
• Uniform and efficient plasma generation with low complexity and nearly constant manufacturing cost irrespective of the number of jets.
• Enhanced safety by separating the high-voltage electrode from the applicator with a dielectric, reducing risk of electric shock or burns.
• Ability to produce homogeneous plasma jets for treating larger or specifically shaped areas.
• Improved versatility for both precision, small-area treatments and larger-area procedures by simply exchanging applicators.
• Simplified maintenance and sterilization, as applicators can be removed and replaced easily.
• Potential to adjust plasma chemistry and operation parameters for optimal biological effects and treatment outcomes.
