Thanks so much for your info on the Nature-Kleen Ozonator. I did a bit more digging after reading your note and it seems to be the best choice for the non-medical machines.
Do you mind answering a few questions? What vendor did you buy yours from? I called one and they wouldn't provide an medical kind of info at all, which is fine, but when I asked them if they carried what I would need for insufflation--and I also asked about a funnel for the lower back--I couldn't get an answer. I guess these folks don't want to touch this kind of usage. So my next question: how do I get instructions for the vaginal, and maybe rectal, insufflation, as well as this funnel method I saw that transmits to through the skin.
