JBL sit down Enema Bag(s)

Not tried it yet, but i have an ordinairy hot water bottle that i modified the stopper so i could use it for enemas, cant see why i couldnt shorten the hose, push it up my bum , then sit on it, might work, might not, only cheap, so if it bursts so what.

I have a homemade JBL that I use frequently and enjoy it immensely. It holds a bit over 3½ quarts, and if I'm patient enough I can get most of it in.

Made from a segment of a truck tire inner tube with the ends folded over and glued. As a machinist I was able to to make a flange that goes on the top (side???), and a Delrin nozzle with an o-ring that snaps into it after it's been filled. I usually take all of it. Works just beautiful.

Over 20 years and haven't had a problem with it yet.

It is certainly possible to make a functional equivalent of the JBL After all, the originals were produced using the technology and manufacturing techniques of 80 +/- years ago, although some of the raw materials have disappeared from the market and some are not practical to produce in very small quantities. A example of the latter is the hard rubber nozzles, but they can now be machined out of plastic stock.

Good luck with a JBl bag if you weigh more than 100lbs or they will burst!

I weigh about 220-230 lbs (~100+ kg) and had my Klystra red rubber JBL from Tyler for many years and many delightful sitting enemas with no rupture or damage. I wouldn’t recommend, however, sitting down on it very forcefully or bouncing on it while sitting.

Your caution is probably valid today, on a vintage JBL bag, but I'm sure it was not true when they were originally made. I think it is more than likely that the the fabric of the stitching has deteriorated and weakened over the years.

The stress on the original bag was never very high as the bag measures about 15" x 10", so if a 200 pound person is sitting on it fully, the internal pressure is under 2 PSI, roughly the same as a regular fountain syringe hung about 4 feet above the point of injection.

Also, the JBL was made of cloth, made waterproof with a rubber coating. The cloth was the strength element as the rubber only made it waterproof. In a modern bag the rubber is the only strength element.

One idea I've had is to use one of the vintage rubber ring/invalid cushions. I saw a member use one as a high capacity enema bag at an EFEST. The inflation valve can be used as a port for filling and to deliver solution with pressure from the bum cheeks. I have a photo in my equipment album where I used one for an enema chair. A 5 gallon bucket makes a decent platform as well. It's not quite as nice as the JBL knock off, but is quite functional and can be taken into the shower or tub.

I guess I was wrong about the JBL bag depending on the condition of the bag I guess if you sit on them very carefully they’ll be ok.

If you don't have a JBL, you can get an idea of a JBL-feeling by taking a sitting enema with a seamless bulb of 1 quart or more. Lube, insert and sit down on it and follow the way of the water in your GI.

On your idea of using a doughnut cushion as an enema bag, something of the sort was proposed many years ago, but I don't know if it was ever commercially produced or marketed. I saw it in the patent literature but no longer remember what it was called or the inventor's name. I vaguely remember the patent was about 100 years ago.

Basically, the invention was a doughnut shaped cushion, possibly with a space in front, like an open front toilet seat, fastened to a toilet seat with cloth tapes plus a valve, hose, and nozzle for taking the enema. In use, the cushion was to be filled with the enema solution, then the user sat on the cushion over the seat with toilet bowl underneath, inserted the nozzle, and opened the tap When the urge to poo became strong the nozzle was removed and the user released everything into the toilet bowl.

If you have a combination bag you can fill it and sit on it with your thighs with the nozzle inserted. But make sure you open the valve before you sit down so the bag doesn't break. I've done this and it works. Not as good as the JBL I used to own but workable.

I'm relatively new to enemas. I would love to put my butt over a JBL, is my dream, but here I can't find 😢

They are extremely hard to find being that the company that makes them has went out of business. Plus rubber and latex products degrade with time. That being said they are a lot of fun. It's a very controlled flow but with pressure higher than a traditional bag. They also hold a lot of fluid so your used to a fleet enema or a one quart bag you'll have to work up to taking the whole bag. Also they do have a tendency to leak while your receiving your enema. That being said if you can find one in good shape you should pick it up although they are not cheap.

I really hope someone would take it upon themselves to make a silicone-based JBL. I've got a decent collection of enema delivery systems, but the JBL has eluded me. I think with modern manufacturing and materials, you could overcome the original design's shortcomings.

Frankly, I doubt a silicon version of the JBL is doable.

The original JBL, both the early 1900s version and the later,, kidney shaped, version sold into the 1950s, were not made the way most all enema bags and hot water bottles after approximately WW I were made…. in one piece of rubber without any seams or reinforcing material

The early bags, made in roughly the 1870s though WW I were made of rubberized cloth, similar to the original MacIntosh rain wear. The cloth seems similar to a light canvas, and is smeared with a layer of rubber, perhaps 0.025" thick. The rubber sticks to the canvas and waterproofs it.

An original JBL bag is cut out from two sheets of this material, placed cloth side to cloth side, and the perimeter sewn. A narrow strip of the same material is then bent 180 degrees over the seam and sewn again. I suspect this tape is also covered with rubber for better waterproofing. If you look inside a genuine JBL bag, the whitish cloth is visible. Also, if the cloth rots, the bag fails when someone sits on it. Been there… it makes a giant mess…. 5 quarts of water, sometimes with poo.

The point is, a JBL replica would have to have something strong that can withstand the internal water pressure. Plain silicone won't.

Has anybody ever seen a silicone Combination syringe? I've looked, completely without success. Same reason, IMO.

I do think, if the correct rubberized material can be sourced, replica JBLs could be made using the original design. It may be an opportunity for a cottage industry. Complex machiney is not needed.

As anyone knows who has sat on an original JBL, it will really fill a person with far more warm water than any other type bag, virtually without any cramping or discomfort, slowly over about 15 minutes, which soon thereafter causes an extremely thorough and complete poo. In fact, the JBL was not really sold for enemas. It was marketed for home colonic irrigation

FWIW

I discovered a way to siliconize material. I'm going to have to look it up in my Utube files. Since the original JBL was runberized cloth, I think using a cotton duck material would make for strength, so it wouldn't rupture. The problem is trying to make the combination syringe and valve. Then what to use as a stopper, for filling.

I thought about using a 6 litter enema bag, but the problem is still the same, what to use for the stopper, and how to make a syringe.

I forgot to mention, I can use my worn out blue jeans as the cotton duck material.

Then I get hit with a brain storm! I'll have to go trolling around the plumbing section in a hardware store. And examine the hardware! I'm sure I can find a way to close it off.

I punched a rather large hot water bottle. It has a stopper. My plan was to machine aa valve with a screw on nozzle.

Make a slit in the bag, insert the plastic nut, then screw on the valve with its o ring. I've been machine enema nozzles and the valve would be more complicated. I don't know about 3d printing.
