An atmospheric-pressure plasma jet generating device is disclosed, which comprises a housing, a discharge tube, an air inlet, and an outlet. The air inlet is connected to the outlet and the discharge tube. The discharge tube includes an internal electrode, a first dielectric material, and an external electrode. The first dielectric material is placed between the external electrode and the internal electrode, and there are some channels between internal electrode and first dielectric tube. An external power source is electrically connected to the internal electrode and the external electrode to generate a high electric field within the discharge tube. When the working gas flows through the discharge tube from the air inlet, the plasma is generated by the high electric field, and then flows out through the outlet. The present invention can generate non-thermal atmospheric-pressure plasma jet for biomedical processing. |
