RÉSUMÉ

A homemade cold plasma jet device for medical application is introduced here. It consists of a microsecond-pulsed power source and a handheld jet gun. The pulse width is 1.2 μs, and the average plasma power is <10 W. Both helium (He) and argon (Ar) gas were used to generate touchable cold plasma jet, and the maximum jet lengths were 7 cm and 3 cm, respectively. Pulsed voltage and gas flow have significant influence onjet formation. The emission spectra of the He and Arjets were compared. When Staphylococcus aureus was treated on a 90-mm agar plate for 0.5−2.5 min, bactericidal spots of 0.5−5.0 cm were obtained. In terms of disinfection of Staphylococcus aureus on a 10-mm quartz plate, Ar plasma performs more efficiently than He plasma.
