Peristaltic pumps

Hi,

after watching this movie:

https://de.xhamster.com/videos/enema-pump-test-first-flush-8164987#mlrelated

a new project was born:

the planning and construction of an enema apparatus, where different peristaltic pumps are the central parts.

The required switching power supply including a speed control for the motors are also already available. By means of a remote control, the pumps can be individually switched on and off and regulate the speed of the motors. This increases or decreases the enema velocity.

The special feature of peristaltic pumps is that, by design, they have a pulsating liquid flow. That should give a special pleasure.

I will report on the individual construction phases and start a detailed picture gallery.

After using pumps of every type the best most reliable and easy to control flow rate with out building much pressure is solinoid pumps simpler and smaller in size in line style

While the linked video is interesting, it looks like the actress was acting.

Generally, the tidal volume of small peristaltic pumps is not large. Maybe 10 ml. This is a similar tidal volume to the P*I*E machine, which produces some sensations, but far less than a Higgenson syringe squeezed rapidly, which typically has a tidal volume of 20 ml to 60 ml. Most are toward the smaller size.

If a colon hydrotherapist "crimps" the outflow hose on a closed system, the tidal volume is probably in the 60 ml range and can produce intense feelings.

I'm not aware of any commercial system or apparatus that can replicate a closed system crimp.

Instead of the peristaltic pumps why not just get a larger orifice direct acting solenoid valve and connect it to a bag/bucket/can hung 5-6 feet high? You can cycle it with a simple astable multivibrator and driver or program a Arduino or similar to turn it on and off to get the surge. You could have different sized valves to get a "surge pattern" too.

How about just hanging a bag and using the ramp of click step valves sold with enema bags everywhere? You can adjust the heights with a rope.

You can also connect the enema tube to the hand spray in your bathroom. For those worried about the PRESSURE which is NOT the FLOW RATE, I posted how to make a pressure regulated hand shower ten years ago.

I will have to look for that post and post a link to it.

WOW.

Finding that was easier than I thought!

@SwitchableSusie

Susie, the problem with solenoid valves is water has inertia. The water column in a typical enema hose is ca 6'. If you want to pulse at a reasonable rate, say a Hz or so, just opening a valve to gravity flow doesn't really work well. You need more force (pressure * area) behind the water column.

If you use a motor driven piston pump, the peak pressure at the pump at the start of the flow is quite high. That is of necessity to get the column of water flowing.

There used to be a device called the "Miracle Enema". It was similar to the currently available Coloclean, but it had a sort of peristaltic pump as part of the speculum. Essentially there was a ca 8" length of rigid plastic tube lined with a length of latex surgical drain. This assembly was directly connected to the speculum. When the speculum was in place and filled with water, air was pumped in between the plastic tube and surgical drain, causing a pulse of water to flow into the user's colon. It felt pretty great. Here us a pic:

https://img.techpowerup.org/190823/picture-54.jpg

The red thing is the stopcock for fill/release. (pretty inconvenient foir srelf use)

The blue thing is the speculum with balloon cuff

The clear part is the outer tubing lined with the surgical drain.

With this device, the pulsing was achieved by compressing and releasing a rubber squeeze bulb.

Since the pump device is essentially at the user's rectum, the issue of water column inertia isn't a factor.

Ah Susie, surely you understand that in kink and sex looks definitely have their place - witness the popularity of lingerie and other sex wear even amongst vanillas. A box that clicks and buzzes and has a 'story' around it "works" psychologically in ways that a simpler alternative might not.

1Hz with a 1/2" tube or so would definitely have a noticeable flow, even with a 1/4" tube you'd get some pulsing. Faster than that and you'd get a slow rate of delivery, but then again get the pulse rate too high and it wouldn't be very noticeable as there is a large area of slow moving water once the rectum/sigmoid is filled.

Hello,

finally, the substructure was finished with three acrylic glass tubes and an above shelf for the equipment. Everything stable.

It stood now the first "sharp" test nothing in the way. What can I say? Just gigantic???.

I have been given and receive endless enemas in my life. I do not want to miss any of them. But that makes you smooth ... ???. Two liters of clear water disappeared within two !!! minutes in the depths of the colon. A 40cm long rubber enema tube find its way without any problems in the depths of the colon. One feels the pulsation of the pumps similar to a light internal massage and felt until the end no pressure feeling. I did not expect it that way. My wife turned the regulator of the larger pump to about 3/4, the smaller to 1/3. The tube and the intestinal tube "danced" in the rhythm of the pulsation.

Toward the end you should pay attention to the fact that it is switched off in time, otherwise you catch a lot of air ... ???. I

Overall, I have to say ... The construction of this device really did not regret, quite the contrary. So far, a absolute highlight... ????

Pictures will follow...

Neptun,

I am so glad to hear that the first test went well. It must have been so enjoyable!

Peristaltic pumps are positive displacement pumps, even though the flow pulses. I have never used one but I expect care is needed if using a double balloon nozzle or other sealing nozzle.

@donga

...It must have been so enjoyable!

..yes, definitely....??

...that's true. I'm going to build a small safety valve that releases at a comparable pressure of a five-foot-high irrigator and relaxes into the fluid containers; just for safty...

Susie,

i guess I'm an old school type at 67 and the gravity-fed flow rate from an enema bag hanging several feet above me regulated by a roller clamp, plus occasional squeezes to my Higginson bulb, is all I need for a great feeling enema. What is a peristaltic pump and what's the point of it for an enema? Thanks,

Eric

A peristaltic pump produces a flow that is not continuous, but slows and speeds up in an oscillating pattern.

It is essentially like a Higgenson, automatically squeezed by a motor

So why would the average enema user need or have any interest in this pump? What is the discussion of this pump doing on this thread? I'm not necessarily against it, but I don't understand what its usefulness is. Thanks,

Eric

Some people like to design things to do things. If Neptun wants to automate his Higginson, why not?!? The "average enema user" can read about it and fantasize as desired, while being satisfied with hir hanging bag and manually-operated clamp.

BTW, how many "average enema users" are here?

Reasonable first answer. Sounds good to me. I have no idea what or who the average enema user is! Maybe I should have said average enema enthusiast. ...............

The surging feelings of a Higgenson given enema are akin to the feeling of an enema given with a bulb. Some people like the feelings.

I use a large 4-5 quart bag with a Higginson pump in line. I love the fast flow down from my bag up several feet above me, but I frequently squeeze the Higginson just to feel the brief fast flow rate. I've never used a bulb, but I love the Higginson.

Sometimes a fast blast of water or a quick squeeze of the Higginson can stop a cramp in its tracks and can really get things moving past a bend in the colon!

Years ago I found a construction manual on the internet to build a dildo which would squirt water in You every time it was deep inside You.

It was not that hard to build it from liquid latex but unfortunately the latex ended up glueing to itself, but the few times I used it was fantastic.

Maybe I will try again and this time I will rebuild an inflatable analplug with a solid core and instead the air I will try to connect an enemabag instead of the air pump and insert a one way valve to make sure the water do not return to the bag and only go into my ass.

I used a simple one way valve from a a cheap handpump for liquids. Dont forget to make a little hole in the tip of the inflatable part.

If I recover the original file on how to build I sure will post it here.

Here's a question that's basic to this subject:

What do you think the volume for the pulses should be? For comparison:

A typical modern Higgenson pump is about 40 - 60 ml (1.5 - 2 Oz) per squeeze.

The 'crimp', done by a colon therapist on a closed system is about 50 ml.

The P*I*E machine pulse is about 10 - 15 ml per pulse.

Also, the largest common adult bulb syringe is about 250 ml (8 Oz)

and, a typical bulb douche is about 350 ml (12 Oz)

In re: "While the linked video is interesting, it looks like the actress was acting".

Just from observing the video... I am commenting here, not to correct you at all,

but I truly do think that the girl receiving this treatment here,

is neither an actor, nor a faker in her ministrations and reactions to it all.

I admit that the main reason I find her behavior "authentic", is because when I am

on the treatment table being administered water and tube in an extended treatment as this,

I am as vocal and reactionary as she is, even more so. Just ask my administrator!

This really has me encouraged to continue exploring the depths of my and her tummy

and the myriad pleasures we continue to find in the depths of this most wonderful

second brain as it is so fondly referred to by many who have studied this part of the

human anatomy. Thank you

I have a Scilog Labtec pump that I wired up a remote trigger switch to, so I can start/stop it from a more comfortable position a few feet away. It works great for colonics and I have the one with the 3000ml/min pump head. I picked it up from eBay a few years back for under $200. The pulsation from the peristaltic action feel great and help reduce cramping.

@Orifice_Attractions

Sorry about taking a long time to respond, but I just saw your post.

IMO, in the video, the woman is certainly getting some solution as an enema. I don't doubt that. But I think her vocalizations, etc, are an act.

Lets try some math. One can see the fluid pulsing in the hose quite clearly. There is roughly 1 pulse per second.

(Why the machine has 4 channels of pumps with the outputs "T" together is a mystery. It's completely unneeded. Maybe it's so it 'looks' complicated.)

Anyway, on each pulse the water bolus moves forward roughly 2" and the hose OD looks pretty standard, hence has an ID of 5/16".

So, if my arithmetic is right, each inch of hose has about 1.25ml of solution in it, so 2" has about 2.5 ml.

This means each pulse injects about 2.5ml, hence in one minute, about 75ml or 3 oz.

A typical commercial Higgenson injects about 2 - 3 Oz per squeeze (50 - 75ml)

This is not exactly a mighty enema, and is unlikely, IMO, to merit a lot of moaning and groaning.

A somewhat similar device, the P*I*E machine, had very roughly the same volume per pulse, but the repetition rate is much higher. While the pulsing of the P*I*E can clearly be felt by the person having the session, the surging sensation is nothing like what one gets from a Higgenson. IMO, the P*I*E machine is pretty much a letdown. While one does poo, it really isn't different from a closed system colonic.
