DEVICE FOR PROVIDING A FLOW OF ACTIVE GAS

摘要

A device (10), typically hand-held, provides a flow of partially ionised gaseous plasma for treatment of a treatment region. The device comprises an applicator head (52) housing a miniature plasma cell (16) in which gas flowing through the cell from a gas source (22) can be energised to form a non-thermal gaseous plasma, and a plurality of electrodes (26, 28) for receiving electrical energy from a source of electrical energy for energising gas in a plasma forming region (18) in the cell to form said plasma. The applicator head (52) is detachable from the device and may be of a size and configuration to enable it to be inserted into the oral cavity of a human or animal.
