to do ozone insufflation you need a medical grade ozonator, which that unit is not.
medical grade ozonators use pure oxygen feeds from oxygen tanks, or sometimes people will use an oxygen concentrator as the oxygen feed. medical grade units can get pretty expensive.
ask ozoneman about specific units and which ones might work for you.
the least expensive units i am aware of are the synergy units. there is a single stage unit on ebay for $400 and a double stage for $680. ask ozoneman if these are reliable.
