Device for generating gaseous species

摘要

The present invention provides a device (10) for generating a non¬ thermal gas species (24) which may be a flow of gas plasma in the form of a gas plasma plume emitted from the device. The device comprises a gas capsule, or pressure vessel, (12) for holding a gas or gases (14) under pressure and forming a flow of gas through a reaction generator (16) to an applicator (18) when released from the capsule. Gas released from the gas capsule is energised in the reaction generator to form a gas plasma. The device is adapted to be hand-held and operated to allow it to be used for instance for cleaning and whitening teeth.
