An irradiator includes: a piezoelectric transformer accommodated in a housing; a first electrode connected to the piezoelectric transformer, to which a voltage is applied from the piezoelectric transformer; and an irradiation opening that ejects at least one of a plasma generated by the first electrode and an active gas generated by the plasma. At least a part of the first electrode is located between the piezoelectric transformer and the irradiation opening.

Irradiator and plasma apparatus

An irradiator includes: a first electrode to which a voltage is applied for generating a plasma; and a holding member holding the first electrode; wherein: the holding member has a first member and a second member that are in contact with each other to constitute an accommodation space accommodating the first electrode; and a contact surface between the first member and the second member includes a non-perpendicular contact surface that is non-perpendicular to an axis of the first electrode.

Holding member, irradiator, and plasma apparatus

The present invention provides a reactive gas application apparatus capable of easily and surely applying a reactive gas to a target object. The reactive gas application apparatus () includes: a plasma generating unit (), a nozzle () for discharging a reactive gas activated by plasma generated in the plasma generation unit (), and a light source unit () for emitting light toward a position ahead of a tip of the nozzle (). The reactive gas application apparatus preferably further includes a control unit for synchronizing plasma generation in the plasma generation unit and light emission in the light source unit.

Reactive gas application apparatus

The present invention discloses a medical therapeutic apparatus () which generates plasma and blows out an reactive gas generated by the generated plasma toward a target object from an outlet, wherein a temperature of the reactive gas at a target surface positioned at a distance of 1 mm or more and 10 mm or less from the outlet is 40&#xb0; C. or less, and a radical concentration is 0.1 to 300 &#x3bc;mol/L as determined by a hydroxy radical concentration measuring method comprising applying the reactive gas to 0.4 mL of a 0.2 mol/L solution of DMPO (5,5-dimethyl-1-pyrroline-N-oxide) for 30 seconds with a distance from the outlet to a liquid surface of the solution being 5.0 mm, and measuring a hydroxyl radical concentration of the resulting solution by electron spin resonance (ESR) method.
