I have been made aware of exactly ONE case where a double balloon catheter was actually used.
Remember, a lot of this is based on talking to, and in effect interviewing Dad, trying to get him to bring up his old memories. While he has an excellent memory, it may not be 100% Parts were confirmed trading e-mails with my aunt. She was not eyewitness to these events specifically, but within a few minutes after the pre-mature expulsion had occurred she arrived home. That means she overheard or saw little bits and pieces. Enough to confirm that the events occurred in more or less the way they are described.
During one of my parent's many enema sessions with each other, on what was apparently the second enema in a series of "Enemas till Clear" that Dad was giving her, she was unable to retain for some reason. Why will likely never be known!
After apologizing profusely to my Dad and really saying that she had "Let him down" and "Failed" she apparently produced a cedar wood box, about 4 by 7 inches in diameter and a nearly full tube of KY Jelly. She sat the KY Jelly on the night stand and told Dad, "Look at the box" She opened it so the open side faced him. It was a double retention nozzle. Dad turned up his face and said, "What the hell IS THAT?" She said, "I thought you had been doing enemas for a couple of years!" He said, "Yes I have, but I have NEVER seen anything like THAT before!" She said, "Really?" He answered, "Really!"
She said, "well it's a double[balloon retention] nozzle! It will COMPLETELY PREVENT any retention failures!
He said, "How can something like THAT prevent an early expulsion?"
She said, "You are REALLY not familiar with it at ALL?"
He said, "No! I can't even picture how it works."
She says, Well, it has those two triangle shaped structures. One triangle points one way, the other points the other way. You will need to put the end with the three holes in me just like a regular enema nozzle. Once you get to the triangular part, you will need to push he FIRST triangle into me, and leave the second one JUST BARELY OUTSIDE ME! Then we will do the inflation. and only once we have BOTH triangles inflated, THEN and ONLY THEN, you will simply stick the straight nozzle in the other end, and then it's just a regular enema, EXCEPT that I WILL be able to retain until you let the air out of the balloon that is INSIDE me! Until then, it's totally safe! It can't actually come out the other end, no matter WHAT you might have heard!
Then she took it out of the box, shoved the box under her bed, and said, " Here is what you need to do to inflate it."
She apparently spent the next several minutes showing him how to inflate and deflate the balloons, I'm told this was the two inflator bulb style.
Dad, commented, "You sound like you do this fairly often?" Her response, "I wouldn't say 'fairly often.' Once I have had a failed retention, it's for the next two rounds at least, sometimes the rest of the session. That decision is made later in the process.
She says, " I am going to mix up a 2{imp} quart strong soapsuds enema with some glycerin to make it more thorough. When I come out and hang the bag I will repeat the same dose of Ex Lax I took at the start, 3 of the 45mg tablets and one of the 30mg tablets, and then get into [knee-chest] position.
She reaches under her bed, and gets out a dish pan and sets it so that the curved lip is at mattress level, and the other end held up by the night stand itself.
Dad said, "What's with THAT?"
She said, " Just because poop can't come out the top, that doesn't mean nothing can, especially with two rounds of laxatives. I cleared my stomach[We now know that means she made herself vomit. Dad never figured that out until I was at the age where parents are told to watch for signs o bulimia, and we didn't prove it until just recently] before we started, so I really don't think it will happen, but if it does, I'm ready!!" Dad, just said, OH!"
She then got a fresh washcloth and placed it on the nightstand, along with a stadium cup of water with a couple of ice cubes floating in it.
She also beings in an empty coffee can and sets it on the bench at the end of the bed. Dad remembers asking her what it was for. Her response was that she had already done two rounds including the failed one, and she "can't be sure" there is not a pint or so left in her. The can was so that while they were getting the nozzle in and set, if that last pint or so "decided to get frisky" as she put it, "It won't ruin any bedding or carpet!"
She went to the bathroom and mixed the enema she said she would. Apparently dumped the rest of the previous one that was still in the bag.
She came into the bedroom carrying the bag and hung it up about as quickly as she reasonably could, and then went back in the bathroom.
When she came out Dad asked her what happened, she said, "Oh that was just the Ex-Lax doing what it's supposed to! It's OK, doesn't change anything!"
She then took the second dose of Ex-Lax and said, "Now while I'm getting into position you can put some of the KY jelly on the business end of that [balloon] nozzle. NOT ON THE BALLOON ITSELF! on the nozzle."
Dad asked her "Why not on the balloon, that will be the hard part to get in!" She said, "That's EXACTLY WHY!! It will make it too slippery for you to get the grip you need to push it in! My rectum SHOULD pick up enough that it goes in pretty easily. Remember, you have a cooperative receiver. I will relax and even breathe in a way that will make it easier for you. We'll get it right, I'm confident!"
Dad says he was surprised how easy it went in, and how clear she was about each balloon inflation. She said, "Only two things can really go wrong. One, either balloon could burst from over inflation. Two we could underinflate the inner balloon, and my bowels could expel it inflated. The first one has happened to both Mom and Grandma, the second has happened to me."
All of this insertion and inflation went on with Mom in knee-chest position. That means that counting the retention time of 15 minutes for a cleansing enema she must have been in knee-chest for an hour or more!! We all get a sense of how challenging that must have been!!!
Dad also said that they used the balloon nozzle for the other 3 enemas in the session.
