Regarding "diaper" vs "disposable brief"... I've used the term Disposable Brief a few times, with mixed results. I've actually gone into a medical supply store, asked where their disposable briefs were, and got a blank stare from the clerk. When I then said "Adult Diapers", She smiled and said "Follow me, Sir!"
When I went in for my last colonoscopy, I told the prep nurse that I was wearing a disposable brief because I have bladder issues. She said "Oh, a diaper... Ok, that's more common than you think!" A few months ago, I had a CT Urogram, for my bladder issues. They required that I drank 32 ounces of water 30 minutes before my scan. I knew that with my urge incontinence, I would probably not make it, so I wore a diaper to the scan. Sure enough, midway through the scan, I couldn't hold it anymore, and wet myself quite a bit. When the scan was over, I asked the nurse if the scan images would be affected because I had wet my "protection". She assured me it wasn't a problem. Then she said "If you brought an extra diaper, there's a restroom just down the hall, where you can change."
I think the stigma around using the word "Diaper" for adult disposable products is disappearing.
For proof of this, check out these sites which all sell adult diapers:
Northshore Care
LL Medico
Carewell
Avacare Medical
Wellness briefs
Allegro Medical
All of these sites use the word "Diapers" as much or MORE than the word "Briefs".
Now Google the phrase "changing adult disposable briefs", see what pops up more. I rest my case.
When do I use the term "Disposable Brief"?? If I'm talking about Depends RealFit Briefs, I'll call that a brief, or pull-up. It goes on like under pants. If it tapes on, I call it a diaper.
So you want a new slogan?? "Diapers! They're not just for babies anymore!"
