Injection device of liquid containing active species and sterilization & extermination method

Avoid temperature rise of the injection device due to plasma and maintain a high sterilization effect

Summary

　Injection device of liquid with active species have been developed in order to disinfect and extermine pathogens and pests using plasma. This device is configured to create plasma to generate the active species, and to inject the liquid containing the active species through a jet. However, the heat of plasma raises temperature of the liquid in the reaction vessel, and the short-lived active species may be deactivated if the plasma discharge time is too long so the sterilization effect may be reduced.
　This invention can provide an injection device of liquid containing active species and sterilization & extermination method that can maintain a high disinfection effect even when the plasma discharge time is long. This invention has a dissolution injection means containing active species which is obtained by dissolving plasma-active gas into liquid and a cooling means to prevent the temperature rise in order to maintain a high sterilization effect.

Effect

Avoid temperature rise due to plasma of the injection device of liquid containing active species
Maintain high sterilization effect even for a long plasma discharge time

Application

● Disinfection and sterilization of medical instruments and organisms, etc.
● Disinfecting and eliminating pathogens and pests attached to plants, soil, fertilizers, etc.
