Inflatable hangers and/or Uli things

I got all the stuff to make a Wench and will put it together tonight or tomorrow. I’ll start out making one per Cap’s instructions.

FYI, got the 1”x 4” grippers at Lowe’s. They didn’t have cable clamps. :(

I got the velcro in the sewing/crafts & hobbies section of Wal-Mart, and a package of cable clamps in the electrical section. This Wal-Mart carries some Waxman products, such as felt pads and such, but not the grippers.

Cap and others, this may need a separate thread, but I’ll stick it here for now:

We’ve had several threads about the possibility of using a blood pressure cuff as a hanger attachment and/or Uli device. My idea has been to use the valve section of a bicycle inner tube, cut off and sealed an inch or several on each side of the valve, with a homemade nylon outer covering to constrain it. Basically a mini-blood pressure cuff.

For use as a hanger, the thing would need some rigid or semi-rigid pieces rigged up to apply more pressure on the sides of the shaft than the top. When I read about the Wench I had one of those “Duh” moments. Velcro and grippers. There you go.

Imagine a Wench with an inflatable air bladder sandwiched in the middle, with a valve stem protruding somewhere. Attach a squeeze bulb (quick release fitting?), and pump it up to tighten. No need for a cable clamp.

The air bladder should produce an even pressure over the whole surface of the grippers, meaning the hanger wouldn’t have to be as tight to support a given weight. In theory, it should be more comfortable and just plain better. :)

I haven’t experimented with this yet, but encourage anyone interested to give it a try. It’s definitely more work than the standard wench. You’d need an inner tube, some nylon fabric, probably a sewing machine, misc. other parts and tools, and the will to fuss with it. I’m not sure what the best way is to seal the cut-off ends of the inner tube. Maybe a combo of contact cement and stitches?

Just wanted to throw out an idea for the adventurous. I’ll report back after I’ve made and tried my original Wench.

Pasi, yeah, that’s the idea.

This page presents a possible store-bought solution (U.S. only) for inflatable innards. I don’t know if a guy would need the infant or pediatric size - I don’t understand the measurements they give. Has anyone tried one of these small cuffs?

Maybe add some extra velcro to hold the grippers in place, or even glue them directly to the nylon? I don’t know, just thinking out loud.

I haven’t looked up the shipping charges, but these only cost about the same as parts to make a standard Wench. I’m sure there are other sources.

I split this out to not interfere with the rest of Capt’s Wench thread. I should have started a new thread to begin with.

Turns out Pasi has alread experimented with an air hanger. Here are the pics he posted.

I think it’s a good idea worth more exploration.

I was thinking about this very idea last week! There is no new idea under the sun, I suppose. <laugh>

I’m guessing that those measurements indicate the size of arm they will encircle. Probably determined by the overall length of the strip and the length of the velcro portion.

Hobby-
I can’t help think “Uli Thing” when I view these smaller blood pressure cuffs.
I might order one just for the hell of it. I’m pretty content with the Wench as is but I encourage you and anyone else to pursue this concept as a hanger.
But on the subject of Uli, who hasn’t been impressed by the intense but painless constriction that is experienced via a blood pressure cuff? And if I understand Bib’s Uli Thing correctly, the success of it depends heavily on your ability to slowly and steadily tighten it in minute increments. I’d imagine that one of these cuffs offers that in spades.
If the dimensions of it are an appropriate size it might work. I see a “neo-natal” size offered. I would imagine that this one is very small. Too small? To little pressure?
Is there a doctor in the house?

Not a doctor! But if I’m reading these sizes correctly then the infant cuff would work for guys up to around 5.5” (including whatever wrap they decided to use) and then the pediatric would work up to about 9.5”.

Actually, since the pediactric starts all the way down at 9cm (3.5”), probably everyone here would be able to use that one.

This page listing disposable neonatal cuffs confirms it. Can’t tell though whether they are practically useful at the maximum stated size, which is a concern.

The pediatric size on the Keomed site is 9cm wide (3.5") and handles 9cm to 25cm (9.8") girth. The infant size is about 2" wide and accomodates 2" to 5.9" girth. Tough call which to try.

Keomed says they are tested to 1000mm Hg. If the online converter I’m using is correct, that’s about 19.3 psi. A full size cuff on your arm gets very uncomfortable at 200mm Hg, so these should be plenty stout.

>I can’t help think "Uli Thing" when I view these smaller blood pressure cuffs.

Me too, but if all it takes is adding some velcro, grippers and strap to make a hanger, might as well have a multipurpose thingy.

For a hanger I’d be tempted to choose the 3.5" wide model to provide more contact area. The grippers come in 4" lengths, so no problem there. OTOH, for a Uli-only or dual purpose device, the 2" width would be better if it can handle enough girth.

I held 2 strips of grippers against my flaccid dick and measured about 5.25". 5.9" max cuff size might work for those of us with small-medium flaccid girth.

What about check valves? The one on my old cuff leaks slowly. Don’t know if they all do, or if mine is just old and tired. Obviously any leak would be unacceptable. I like the idea of using a squeeze bulb to inflate. A tire pump would be too bulky, even with a neck strap. :)

I’d imagine that the exterior Velcro band as an outer skin would greatly increase the pressure the cuff is capable of achieving - it would prevent outward expansion - I don’t know if there’s a way of quantifying it but that would render any and all of those psi numbers pointless (as impressive as they are).

Personally I think that the more contact length-wise the weaker the grab (at least potentially). Better to concentrate/contain the lateral pressure to as small an area as possible. The grab can be stronger and it offers less room for error. Also guarantees more tunica stretch. 3.5” is a lot of coverage - (overkill?). That 2” cuff is very appealing, provided it can handle the girth.
The biggest test in my opinion, is going to be whether the grippers somehow compromise the overall constriction of the cuff. On the other hand there is a risk that if the cuff is too successfully in its squeeze, the total circumference ‘strangle’ it creates will cut off all circulation to the glans. There might not be that much difference between this effect and the old “noose” type hangers that nearly killed many a dick in the old days.
All of this is speculation until someone tries it. The price is right - and win or loose ala hanger, Hobby, I can’t imagine this not working as a Uli Thing when using it with the outer velcro “skin”.
Hobby - you have a blood pressure cuff? Have you used it Uli? Or is it adult size?
I’d imagine any leak (intented or not) could be dealt with.

I have a full size cuff, but the bladder is ripped beyond repair. :(

I’m taking a break from PE until Jan. 1, so it will be a while until I try one of these things.

More area increases the clamping force a given pressure applies. Say, for example, 4 psi is applied to 2” x 1” grippers. 4 square inches x 4 psi = 16 lbs. of “grip”. 3.5” x 1” grippers have 7 square inches of area. Multiplied by the same 4 psi = 28 lbs.

This is why skinny bicycle tires need 80 or more psi, but fat tires can support equal weight at a much lower pressure.

It’s also the basis of why I think this has the potential to be a better gripping method than a cable or hose clamp. A medium size cable clamp is only 1/2” wide. Granted, the velcro and rigidity of the grippers spreads the force over a wider area than that, but an even pressure over the full length of the grippers should provide a better hold.

Since a wide cuff requires less pressure, it should avoid a noose effect better than a narrower cuff. Some pressure on the top and bottom of the shaft is ok, and even desired, IMO, to keep the penis from squishing out from between the grippers. The Wench is better about this than some hangers since it supports the penis all around.

If these cuffs or homemade bladders put too much pressure on top, a bridge could be made to shield the dorsal side.

As you said, it’s all speculation at present. Until my troublesome vein heals I’m stuck at the drawing board. I wish Pasi would tell us more about his air hanger.
