1Object-affected harmful factors
If conventional plasma technologies are used for cancer therapy and wound healing, then sterilization and curing effects are achieved, but the ability to selectively target cancer cells while minimizing damage to healthy cells is insufficient
Solution Approach 1:
The capacitor structure creates localized high electric field regions at the electrode surfaces and within the honeycomb channels, generating plasma with concentrated reactive species exactly where needed. This local concentration of reactive oxygen and nitrogen species enhances the selective damage to cancer cells while allowing control over the treatment zone to spare healthy tissue.
Solution Approach 2:
The invention utilizes charge-discharge cycles of the capacitor to dynamically control plasma generation parameters. By adjusting the voltage, frequency, and duty cycle of the electrical input, the concentration and type of reactive species can be modulated to achieve selective cytotoxicity against cancer cells while preserving normal cells.
2Productivity
If plasma is generated at high temperature, then reactive species are produced effectively, but the treatment cannot be applied at room temperature and atmospheric pressure
Solution Approach 1:
The capacitor-based plasma generator produces non-thermal plasma where electronic excitation and ionization occur without bulk heating of the gas. The reactive species are generated through electron impact ionization and excitation at room temperature, maintaining the plasma in a metastable state that delivers reactive oxygen and nitrogen species without thermal damage.
Solution Approach 2:
The invention replaces thermal plasma generation mechanisms with electrical discharge mechanisms. Instead of using high temperature to produce reactive species, the capacitor uses electrical energy to create strong electric fields that directly ionize and excite gas molecules, generating plasma and reactive species through electrochemical reactions rather than thermal processes.
3Reliability
If complex plasma systems are used for medical treatment, then comprehensive treatment effects are achieved, but portability and ease of operation are reduced
Solution Approach 1:
The plasma generation system is segmented into modular capacitor units with honeycomb structures. Each capacitor module can independently generate plasma, allowing the system to be scaled or configured for different medical applications. This modular approach maintains comprehensive treatment capability while enabling portable, bedside, or even home-based treatment devices.
Solution Approach 2:
The capacitor-based plasma generator is designed to be multi-functional, capable of treating various conditions including cancer therapy, wound healing, and sterilization using the same fundamental device architecture. By adjusting operational parameters such as voltage, frequency, and gas flow, the single device can deliver different plasma compositions and reactive species profiles for different medical indications, eliminating the need for multiple specialized devices.
