Oh my! They use those things on dogs and cats. Poor you! ;-)
One of my dogs had to have one of those plastic collars put on her, when we had her fixed...one day I was walking her along the beach, and I ran into some foreign tourists getting off a tour bus...they had never seen one of those collars on an animal...those tourists were supposed to be looking at the beach, but instead they were all crowded around my dog, just amazed at what she was wearing...
When I explained what it was for, the response was, "You Americans are so very smart"...I had to laugh at that one...they said they were going to carry this idea back to Germany(which is where they were from), and let their vets work on it...
This was about 15ys ago, and from their reaction, this collar on a dog, was something they had never seen before...my dog was a tourist hot spot...
