Plasma Therapy Device Turbulent Flow Gas Yield
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional devices for indirect plasma therapy often fail to achieve satisfactory treatment results due to inefficient production and delivery of reactive gases, leading to suboptimal therapy outcomes.
Innovation Solution
The device enhances plasma therapy by creating a buffer region through turbulent flow in the reaction chamber, where process gases are influenced by electromagnetic fields, increasing reactive gas yield. This is achieved by designing a reaction chamber with a smaller outlet opening than inlet, generating dynamic pressure and guiding gases back into the discharge zone, and using a circular cylindrical peripheral wall with a specific diameter and length to optimize gas flow and minimize collisional quenching.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional devices for indirect plasma therapy are used, then the treatment can be applied, but satisfactory treatment results cannot be achieved due to inefficient production and delivery of reactive gases
Solution Approach 1:
The patent introduces a movable component (plunger) within the reaction chamber that can be moved between a first position and a second position. This movement dynamically controls the gas flow path, allowing the process gas to be directed either through the discharge zone for reactive gas generation or bypassing it. This dynamic control enables optimization of both reactive gas yield and therapy reliability by adjusting the flow characteristics according to treatment requirements.
Solution Approach 2:
The patent employs parameter changes by varying the flow rate of process gas through the reaction chamber. By controlling the speed at which gas moves through the discharge zone, the system optimizes the interaction time between process gas and electromagnetic fields, thereby maximizing reactive gas generation efficiency while maintaining reliable therapy delivery.
2Stress or pressure
If the outlet opening of the reaction chamber has a smaller opening area than the inlet opening, then dynamic pressure is generated and turbulent flow is created, but the gas flow path is restricted
Solution Approach 1:
The patent uses a movable plunger to dynamically adjust the gas flow path in response to the pressure differential created by the smaller outlet opening. The plunger can be positioned to either restrict or allow bypass flow, providing dynamic control over the balance between pressure generation and flow ease, resolving the contradiction between creating dynamic pressure and maintaining operational ease.
Solution Approach 2:
The plunger acts as an intermediary component between the inlet and outlet openings. It mediates the gas flow by providing an alternative path around the discharge zone when needed, thus easing the gas flow restriction caused by the smaller outlet opening while still allowing the system to generate necessary dynamic pressure when the plunger is in the restricted position.
3Productivity
If turbulent flow is generated in the reaction chamber, then a buffer region is formed and reactive gas yield is increased, but gas molecules are subjected to collisional quenching
Solution Approach 1:
The movable plunger enables dynamic control of the gas flow regime. By adjusting the plunger position, the system can optimize the balance between creating turbulent flow (which increases reactive gas yield through enhanced mixing and exposure to electromagnetic fields) and minimizing excessive turbulence that would cause collisional quenching and loss of reactive gases.
Solution Approach 2:
The patent applies partial action by allowing some gas to flow through the discharge zone for reactive gas generation while enabling bypass flow for portions of the gas stream. This partial engagement with the discharge zone prevents excessive turbulence and collisional quenching while still achieving sufficient reactive gas production for effective therapy.

Function Achieved in This Case
The enhanced device increases the yield of reactive gases, leading to improved therapy success by maintaining a balance between gas enrichment and flow, reducing unwanted gas abreaction and collisional quenching, and allowing for effective application of reactive species to treatment areas.
Implementation Method 1
the reactive gases are generally formed by transferring sufficient energy in a gas discharge. In this type of gas discharge a plasma composed of partially or fully charged particles is produced
Implementation Method 2
a plasma composed of partially or fully charged particles is produced, from which reactive gas species develop
Implementation Method 3
Plasma is often generated in electrostatic or electromagnetic fields, e.g. by alternating or direct current excitation or microwave excitation
Implementation Method 4
The turbulent flow in the reaction chamber and/or the gas discharge zone leads to a buffer region being formed therein
Implementation Method 5
This gas flow aligned to the outlet opening then gives rise to dynamic pressure before the outlet opening
