Selfbondage with rubber vacuum sack and USB power board

Post by StephanBeckenbauer »

Hi,
a search in this forum only led to two results about this topic. Both contained questions if somebody has done selfbondage with a vacuum sack. If I missed a post and this scenario existed, please excuse the double post.

This is what I did yesterday afternoon, as already said in the topic it involves a vacuum rubber sack and a USB controlled power board.

Materials needed:
  1. Vacuum sack, here's an video which one I bought:
    http://www.youtube.com/watch?v=RXnSf48TDZw
    I don't want to advertise, but in the description is an email address of the german guy who sells these things for around 130€. Worth it in my mind, but check yourself. Maybe there's also something in the DIY section of this forum. I didn't check thoroughly.
  2. USB controlled power board:
    http://www.amazon.de/reVolt-Automatisch ... osenleiste
    This power board is plugged into a normal outlet and via usb in your computer. The usb only works as a on/off switch. If you shutdown your computer, the power board shuts down all the devices plugged in. Usually used to switch off displays, printers, sound system etc.
  3. Time controlled power outlet (something like this: http://www.amazon.de/reVolt-revolt-Digi ... osen+timer). You need to be able to set an interval in the future where power is enabled. Not only a countdown-timer.
  4. Thin tube (1 to 1,50m long)
Software needed:
  1. Blowjob Trainer (search in this forum)
  2. Shutdown Batch-File (see details further down)
Preparation Materials:
  1. Plug outlet timer into outlet (power on in 15 minutes, power off in XX minutes - this is your safety fallback)
  2. Plug USB outlet into outlet timer
  3. Plug USB from outlet into computer
  4. Plug Vacuum cleaner into USB outlet
  5. Tape Vacuum cleaner onto tube that sucks air out of vacuum sack.
Preparation Software:
  1. Create a batch that shutdowns your computer. Typing "c:\windows\system32\shutdown -s -f -t 00" in a textfile saved as shutdown.bat works perfectly for me. If you have no idea what to do, google it. Test it.
  2. Configure Blowjob Trainer, also set newly created batch file to be executed after completing task. Test the blowjob trainer thoroughly and many times. Work with small max limits. Just make 100% sure you can still finish the task.
And let's start:
This is the basic setup:
Image1.jpg
Get yourself into the vacuum sack. Add the additional small tube so its running through the opening for the head so that always a little bit of outside air is flowing into the vacuum sack (small blue tube in the picture)
When the power goes on, the vacuum cleaner sucks the air out and you are completely helpless. Be careful, that vacuum sack is strong!! Start sucking, when finished the computer shuts down and the power board switches off the vacuum cleaner. Air runs through the small tube into the sack and you'll be able to free yourself after a couple minutes. If laptop doesn't shut down, the timer shuts down the vacuum cleaner. In case of power off, everything is switched off anyways.

Notes:
Be careful, it took me a long time to make this relatively foolproof.
Problems I encountered:
At my first tries with the vacuum sack I had my hands near the opening for the head to let in air. Don't underestimate the power of vacuum cleaner! And if your heands are at the wrong position you will NOT be able to move them one centimeter if the air is sucked out. That vacuum sack is unforgiving! Without the extra tube to let the air in it will stay tight for hours. Don't be as stupid as me, I had to roll from the bed to the floor until the tube which goes from the vacuum cleaner into the vacuum sack was pulled out and air could get in. Expect cramps and limps falling asleep. It takes time to find a good position. Experiment with very short periods of time inside the vacuum sack.

Last but not least:
I did this a couple times and still only go for very small limits:
Time interval for timer-controlled-power-outlet: 20 minutes (-> safety off after 20minutes)
Blowjobs: start with 10 and max of 30. (I still fail quite often, remember your restricted movements. This is usually more than enough). After these short sessions I'm exhausted like after a one-hour-workout in the gym. It feels absolutely fantastic though :)

Have fun,

This is an excellent way to die !

Vacuum sacks/beds and self-bondage simply don't mix. As the OP found, they are extremely restrictive. Add computers into the mix and you are compounding the opportunities for it to go terribly wrong.

We've discussed this at length and cannot recommend the idea, and will do our best to discourage people from contemplating trying it
be a switch, double the fun :-)

We must not forget the death of Mr. Kemp (organist in Hardwick Baptist Church):

Mr Kemp's organ is now kept in the church and used in services as a way of remembering him.

you cant forget that matt from kink engineering died in a vacbed, and he designed them! I have used a plastic sheet over a waterbed as a makeshift vacbed a couple times, but just don't feel the risk is worth it to try that anymore. what makes your scenario even more dangerous, is the fact that you are using your only airway(mouth hole) to complete the blowjob trainer tasks.
For those that get it, no explanation is needed. For those that don't, no explanation is possible.

If I understand correctly the sack goes up to the neck and do not cover the head so breathing should not be a problem :hi:

Vac beds (and sacks) are deadly for several reasons!
  • (Let's get the obvious out of the way: you can't move! This is a risk for any self-bondage, though, so we already assume this one.)
  • Vacuums are very unforgiving. They will continue to suck air pressure until they lose power or break for one of various reasons.
  • One of the best ways for a vacuum to fail is for it to overheat. When an AC motor overheats, you run a very real risk of electrical shorts and fire! Not something you want while you're helplessly immobilized. :shock:
  • Speaking of overheating, YOU run a risk of overheating and passing out from exhaustion. The necessary plastics/rubbers to have an effective vacuum bed preclude allowing your skin to breathe and shed excess heat. You can quite literally cook yourself from the insulating properties of vac-bed materials. The heat your vacuum will be putting out won't help matters either, since the heat it produces will further diminish your body's ability to cool off by raising the ambient temperature.
  • If you have weak lungs, asthma or other respiratory issues, cold/flu symptoms, etc., the pressure from a vac-bed on your chest can cause complications. It's even possible (though thankfully unlikely) that you can have a lung collapse from the vacuum pressure.
  • Assuming your vacuum is strong enough to immobilize you by pulling sufficient air volume/pressure out of your "sack", that will put any and all exit membranes under a great deal of pressure as well. A neck opening can hardly be considered safe, as it will constrict just as much as the rest of the sack!
And this is not an exhaustive list by any means! :shock: There's a reason porn sites generally don't feature these things. When they do, they have entire TEAMS of medical personnel and engineers on hand to get the subject out of it as quickly as possible to address any and all medical concerns.

missed the video showing the vacbed type before. that would take care of the breathing safely aspect, but when matt from kink engineering died, he was in a vacuum bed with a neck opening.
13.Matt’s death was a direct result of prolonged neck compression from the neck gasket. The bed he chose to go in had been custom fitted to Archean, who has a much smaller neck. The baro receptors in his internal carotid arteries signaled to his body that his blood pressure was dangerously high, and this sent off a vagal response to slow the heart. Since the signal of high blood pressure could not be relieved, Matt lost consciousness and the vagal response caused his heart to stop completely.
For those that get it, no explanation is needed. For those that don't, no explanation is possible.

i just got my rubber sack in the mail this afternoon and have been playing in it. it is one that goes from the feet to the neck. its 23" wide the whole length, so your legs have room to move a bit. the neck opening is said to be 19" circumference. my neck measures 27" circumference, it seals good on my neck, but not to tightly. keep in mind this is not a vacuum sack, but it can hold a vacuum because there is no zipper.

what i did, is to pull the neck seal up over my mouth and breath in through my mouth, then exhale through my nose. you can get most of the air out this way, but it will always let some back in when you move the neck seal back to your neck. this allows a little movement to get your arms back down to your sides, then you can squirm around in a nice latex hug! :rofl: :love: when you want to get out, just bring your hands up to the seal and let some air in.

if i didn't have the radio playing, i would have fallen asleep in it, its SOOOOO comfortable! :D

Funny you should ask!

They actually don't say that.

Hmmm... it's not attached to its bearer, and in the state it's in at the moment, it's no more against the rules than any oversized dildo that's immersed in a gross, smelly liquid.

But let's not make this a precedent for extended interpretations of the rules, or else :whip: (or someone's organ is going to be in some smelly liquid :lol: ).

Optical illusion. The liquid (and cylindrical walls of the container) magnify it. ;)

I never tried but this can only be extremely unsafe! And while there is risk in normal SB, not all risk is equivalent so that shouldn't be a warrant to up it to a vac-bed. The risk seems to be magnified many fold so if you do try this (Please don't) I really hope you've taken an equivalent magnitude of back up mechanisms into account. I think the various "clubs" around the world would be more then willing to help you achieve your dreams!
