APPARATUS FOR PROVIDING A FLOW OF A MODIFIED GASEOUS SPECIES

摘要

The present invention provides an apparatus for providing a flow of a modified gaseous species for treatment of a treatment region of a human or animal body. The apparatus comprises a first housing (30) in which is located a generator (36) having at least one electrode (44, 46) which can be energised for forming said modified gaseous species. The housing has a configuration which enables it to be held by hand and operated for treating the treatment region, and comprises an inlet port (56) for a flow gas communicating with the generator and an outlet port (58) for the flow of the modified gaseous species from the generator. A second housing (20) is remote from the first housing and has one or more batteries (22) and a signal generator (27, 28) for converting voltage generated by the battery when located in the second housing into a pulsed high voltage signal. A gas passage (50) extends through the second housing connectable to the inlet port and electrical leads (54) apply the pulsed high voltage signal to the said at least one electrode of the generator.
