Double ballon crisis?

Klystra's double ballon nozzles are out of stock for about 4-5 months...

is there any information/ideas/forecasts about them?

is hope still alive?

i miss them so much 😢

You’re not limited to Klystra. There are other places you can get the same or equivalent products. I posted some quite recently. Do a search — on this site or on Google.

As far as i understand, klystra is the manufacturer of silicone double balloon nozzles,

so main suppliers, like OHN and Beth Tyler, take it from Klystra

there is also another notice of this problem:

or, maybe, i've misunderstand something?

You could investigate these, and perhaps ask other people’s opinion:

Silicone products, no out-of-stock indication:

A similar latex product: http://www.medtech3000.de/doppelballon-darmrohr-p-495.html

I’ve posted about this one, it inflates both balloons simultaneously:

I just learned today that Klystra now has the double balloon nozzle back in stock, at least the F2S variety. I can't say for certain without checking the site if the larger one was delivered too. Their quantities are limited to 8 pieces (as of this evening), but there are more on the way soon. If you've been waiting for one like I have, you may want to act fast.

Klystra’s front page says: ‘The double balloon nozzles are back in stock but in limited quantities. We had so many on back order to our resellers that we could only keep a few for ourselves.’

Both sizes F-2S and F-3S are shown as available, with more stock expected in a few days.

I would like to see a review of the clean stream silicone double balloon nozzle. It is a cheaper knockoff of the Klystra nozzle.

From what I have read it is prone to leaking / breaking & made much more cheaply. I would be interested to hear from someone who owns one / has detailed photos.

Tk for the information

I can say from first hand experience that is true.

Never used a Klystra, but the Chinese model has silicone of irregular thickness and the glue joints aren't always great. I've had to glue a tear together in mine and will soon need to re-glue the inflation bulb breakout "tree".

While "that company" does make Foley catheters under "that brand name" they do get pissed off (perhaps an appropriate double entendre?) when that brand name is used in a fetish context. That's why Webby asks that people use "balloon nozzle" and "catheter"

I can not make the post asking not to use a certain trademark more visible.

Please do not use the word -

B A R D E X

"B a r d e x" is a trademark of the C R Bard company.

Use the term double balloon nozzle or double balloon rectal catheter.

I'm tired to go trough posts and manually make the changes to hundreds of posts. I have had to do that for years.

From now on I'll just delete ALL posts containing the word B A R D E X.

Seconded. The Chinese knock-off is terrible quality. Much cheaper, but not even worth that. Mine lasted less than ten uses before it leaked and I had to throw it out. Waste of money.

I did the same. Ordered a double-balloon knockoff of a Klystra 500 and immediately inflated it to see what it would do. It was so thin on one side that it was obviously going to burst so I tossed it in the dustbin without ever trying it.

I recommend buying the ones from medtech3000. They work pretty well, but they are different from the one Klystra made (I have that one too), the medtech3000 ones are smaller and more comfortable to have inflated inside you for longer periods of time.

Interesting you should say that!

It was just yesterday I was showing my husband one of the balloon-type retention nozzles my Mom Left behind.

One of the first things he said, "Why would anyone inflate THAT with a BULB? It is too hard to control how much you are putting in."

I asked him, "What do you think SHOULD be done?"

"I see a huge syringe about the width of Turkey Baster, and maybe half as long, with the graduations on the sides in cc and ounces. It's what they do in hospitals! That way you carefully CONTROL the amount of air you are putting in that balloon and it will never rupture. At least not when it's inside someone!"

Later in the conversation he said, "While I was not there, Id' bet a few dollars anyway that when your Mom got that BE, they probably used something along the line of a single-balloon retention nozzle that was inflated with a big syringe. Just gives you more control!" .

His engineering mind works like that.

Sizes of the rectum/anal canal vary.

Also you need to be aware of your tolerances. A balloon in the rectum generally has pretty liberal tolerances between "not sealing" and "tearing the rectum". A catheter in a blood vessel has much tighter tolerances.

Try eBay. There are at least 50 suppliers there now.

Probably less expensive too

Spoken like a person with no actual experience using ballon catheters. (You have said you haven't and would never use them in previous posts.)

It is very easy to control EXACTLY how much air goes into the balloons and how large they get. All you have to do is count how many pumps you put into a balloon while you hold it in your hand and that works extremely well. If a balloon pops inside the rectum, the worst thing that happens is the enema flows out of you onto the floor and you have a mess to clean. There is ABSOLUTELY no bodily harm or pain when they break. Other members will attest to this.

There is one other thing involved here. As the balloon inflates, it takes more and more air to make it larger. The volume of air required to double the diameter of the balloon is SEVEN times as much as is already in the balloon! In other words the bigger the balloon gets, the more air that is required for each incremental increase in size. The volume of a sphere is proportional to the radius cubed.

So if you start with 1 pump, to double the diameter of the balloon will take 7 more pumps, and to double the diameter again will require 56 pumps and to double it one more time, 448 pumps! Very simply, it will take a lot of time and effort to create a very large inflation because the larger it becomes, the more air has to be pumped in for each incremental increase in diameter.

That works in theory, but as a balloon inflates, the wall thickness of the balloon becomes thinner, so it takes LESS than the theoretical volume amount of air to increase the diameter of the ball, which is related to the radius cubed because the balloon is more easily stretched.

The balloon will also pop long before you get anywhere near 56 full pumps or times of volume increases.

Hate to tell you this Switchable, but while the balloon may get thinner, the pressure required to inflate it actually goes up because with every pump, you stretch the balloon a little more, and the force (pressure) inside required to stretch it will continue to go up as the balloon inflates until the balloon finally pops, so if it takes more air rather than less. Air is not like water, air is easily compressed.

Even if what you said was true (which it is not), the thickness of the balloon is very small compared to the radius and is actually irrelevant to the discussion anyway. The volume of the balloon material is very very small compared to the volume of air inside. The surfaced area goes up as the square of the radius, and is actually 4*pi*r^2. The actual volume occupied by the balloon material is essentially independent of the size of the balloon until just before the balloon pops (because it can no longer stretch). If you double the diameter of the balloon, you have essentially cut the thickness of the material by 75%. This is why most balloons are opaque when you start to blow them up and become translucent as they inflate. Inflating them occurs by stretching the material. The more you inflate them, the more translucent they become as the material becomes thinner and thinner. There is really no change in the total volume of the material itself, but as the material the balloon is made of stretches, it comes thinner, keeping the volume occupied by the 'skin' of the balloon essentially constant.

Ever notice how much thinner rubber band becomes as you stretch it to put it around something, and that it ceases to stretch just before it breaks?

I agree with most of what you said and all of the math, but haven't you noticed that a balloon is hard to start blowing up but then gets easier until it no longer stretches and it pops? In either case you do not need a syringe to blow up a balloon to know how big it is.

That's a lot of science about balloons. How about you just blow it up until it plugs your ass and keeps water from leaking out! This isn't Rocket Surgery!!! 😄

Has it occurred to anyone that to simply put it that it expands not just in a x, y but also z. So if you keep doubling the amount of air, it won't expand as fast as it did in the beginning.

Balloon inflation is more complex. If you model it as a sphere, the internal volume goes up as the cube of the radius.

But it makes a huge difference what it's inflated with: air, which is compressible and about follows the ideal gas laws, or water, which is incompressible. The actual inflated diameter depends on the volume of air pumped in, the elasticity of the material, and the external pressure surrounding the balloon, at least.

If you are retaining an enema with a air filled balloon catheter and bear down hard, the balloon will decrease in size and may pop out. I think that's why several bowel catheters, like Instaflo, Actiflow and Flexi-Seal as well as bowel irrigation systems like the Coloclean use water filled balloons.

BTW, nobody has yet answered why water is used in Foley urethral catheters. The reason is not the same.

Water is used for both rectal and urethral Foley catheters. A calibrated syringe only makes any sense to fill a Foley with water, because the size of the balloon is then known.

Also, there are a number rectal nozzles, single use, for Barium enemas. The often use disposable inflators of a plastic soft foam filled plastic bag. One squeeze would inflate the retention balloon to the appropriate size.

With one exception, almost none of the balloon catheters I have used are "spherical." I have one non-fluted latex model (single balloon catheter) which starts out as nearly spherical and pretty much stays that way as it is inflated. At best, the fluted nozzles are conical and then continue towards spherical.

There is a reference to air being compressible. Actually, what I think is meant by that is that it follows the ideal gas law (PV=nRT). And at the pressures we are dealing with inside the inflated balloon, this is certainly a valid assertion. Compressibility (from the standpoint of engineering with certain gases) can also mean the degree of deviation from the ideal gas law. Certain gases deviate quite a bit from the ideal gas law at high pressures (methane is one such example). But that has little relevance in this discussion. For all intents of purposes, each squeeze of a squeeze bulb with a check valve delivers nominally the same volume.

What we can say is that for a given balloon design, there is a limit to the elasticity of the polymer (elastomer) before the "links" begin to break and the balloon fails. You can stretch a balloon such that it ends up with a weak point which may eventually fail because of local "overpressure" relative to the local strength of the elastomer.

But enough of this engineering geekdom. Whatever fills and seals is the goal (for a reasonable cost). I get my latex nozzles from Germany. The silicone ones from Clean Stream are different size and feel different when inflated. But ultimately, I've learned how to make each one work. YMMV.

Gases depart from the ideal gas law only when they start to approach critical points, i.e. the combination of temperature and pressure makes them close to changing 'states'. For example carbon dioxide at high pressure at room temperature doesn't behave much like an ideal gas because it is very close to actually liquefying. At room temperature and pressure all gases in the atmosphere can be considered to be ideal. The only exception is water vapor at low temperature (again because it is about to change states), but at low temperatures there isn't enough of it to make any difference. Because there is so little variation in the temperature of the gas in this case, we can use a simpler formula for volume. P1*V1=P2*V2. The volume of the gas is inversely related to the pressure. As the pressure changes substantially there is either significant heating or cooling of the gas. This is significant enough that in an airplane at 35,000 feet where the outside air temperature is often -35F, you actually need air conditioning. The compression of the air to pressurize the cabin really does heat the air to temperatures that are far far above 'comfortable'. However in that case we are usually tripling the pressure of the gas. Inflating the balloon does not raise the temperature anywhere enough to have a significant effect. In small aircraft (typically biz jets), you actually need heaters, not because of the air temperature, but because the surface to volume ratio is such that more heat is lost through conduction out the body of the aircraft than is produced by the compression of the air.

This is way too heady for me.
