20110306006 | DEVICE FOR PROVIDING A FLOW OF ACTIVE GAS | 12-15-2011 |
20120073674 | GAS SUPPLY SYSTEM - A gas supply system is described comprising: a gas capsule enclosed at one end by a pierceable diaphragm; a spacer element adjacent the pierceable diaphragm, the spacer element having a channel providing access to the pierceable diaphragm; a shaft with a piercing tip; and a seal. The shaft, spacer element and seal are arranged so that when the shaft accesses the pierceable diaphragm via the channel, the shaft is caused to enter into a sealing engagement with the spacer element via the seal before the piercing tip pierces the pierceable diaphragm. In an alternative embodiment, no spacer element is provided and instead a seal is provided in a groove in a wall defining a recess at a position so that when a gas capsule is inserted into the recess, the seal enters into a sealing engagement with the gas capsule before the piercing tip of the shaft pierces the pierceable diaphragm enclosing the gas capsule. | 03-29-2012 |

20130147340 | DEVICE FOR PROVIDING A FLOW OF PLASMA - A device for forming at an ambient atmospheric pressure a gaseous plasma comprising active species for treatment of a treatment region. The device comprises a plasma cell for forming the gaseous plasma for treating the treatment region. The plasma cell comprises an inlet for receiving gas from a source and an outlet for discharging active species generated in the cell. A dielectric substrate made of a polyimide encloses the flow path for gas conveyed from the inlet to the outlet and an electrode is formed on the dielectric substrate for energising gas along the flow path to form the active species. A protective coating or lining is located on an inner surface of the dielectric substrate for resisting reaction of the active species generated in the plasma cell with the material of the dielectric substrate. | 06-13-2013 |
20140234795 | DEVICE FOR GENERATING GASEOUS SPECIES - The present invention provides a device for generating a non-thermal gas species 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 for holding a gas or gases under pressure and forming a flow of gas through a reaction generator to an applicator when released from the capsule. Gas released from the gas capsule is energised in the reaction generator to form the gas plasma. The device is designed to be hand held and hand operated so that it may be used for cleaning and whitening teeth as well as other applications. | 08-21-2014 |
