Today we present you Pup Loki’s DIY for a tool which will enrich your Breathplay. We think that a lot of drones and gimps will enjoy it.
Breath play, also called Erotic asphyxiation (EA), includes the practices of controlling a persons air supply, inducing various aromas into it or also cutting said supply off over various means such as chocking, holding hands over their mouth and nose, or also with the help of machinery and tools, such as rope or masks.
It is seen as one of the most risky practices in BDSM, and has likely been the cause of the most injuries and fatalities occuring in the fetish scene due to play. It is unsafe and dangerous if not done extremely professionally, not only due to the risk of choking to death, but also possible neck injuries, long-term brain damage, burst blood vessels etc etc.
Breathplay should only be engaged in very controlled circumstances and sane states of mind, and always with another person, never alone. We do not take any responsibility for any accidents and health injuries through this build or derived from this DIY builds.
KINKFINITY has made a separate article where you can find more information about breath play. Loki also recommends contacting a professional for learning safe practicing when you are interested into it, giving this link as reference. Please be careful when you practice these things. Now onto Loki’s personally written intro.
I haven’t posted this bit of DIY before as I’m in two minds about giving people such potentially dangerous tools, but then it’s just some bits of pipework so it’s hardly an immense secret. That said, although it’s simple, this is for people that know what they’re doing and are looking for something to make play easier and safer.
The idea of this build is to give you an idea of what I made as a framework to customise for yourself; there’s no right or wrong setup although there are some fundamentals.
The main components are half-inch (~19 to 20mm outer diameter) PVC pipe and fittings . I’ve used:
- 1/2″ inch 90 degree Ts
- Plain sockets / Coupling (to provide a female connector for the poppers vial and for the gas mask hoses)
- 1/2″ inch Ball Valves
- 1/2″ inch Pvc Pipe
- Pvc Cement (for welding parts together)
- 40mm Gas Mask Hose
- 20mm Clear Pvc Tube (2mm = ~0.76 in)
- Bijou Bottle
- Stainless Steel Jubilee Clips (for Gas mask tube fastening)
- Wall or otherwise Fastening clips for mounting
- Cutters / Saw
(Complete KINKFINITY Online Shopping List can be found at the end of the article)
In my case everything is solvent welded together (you just wipe some gunk in the pipe, push, wait a minute, and it’s stuck forever) but you can get screw fit. The pipe can be sawn to the right length but for a couple of quid you can get cutters which make it super easy.
Se7en note: When having built this, please do not use it immediately. Depending on the cement, the fumes can be dangerous.
I’ve used grey half-inch pipe throughout but use whatever colour you like. If you’re in the UK then plasticpipeshop.co.uk will supply your needs.
As far as kink components go:
Be aware that there is a quarter turn between full on and off, so precise dialling of (eg) poppers can be tricky, but it should be ok for most needs.
Gas mask connectors
If you attach a socket (i.e. female to female) this will give you a slightly larger outside diameter which will enable you to attach a standard 40mm gas mask hose. I used the type that has a clip fitting so I could remove one end and then a stainless steel jubilee clip to tighten it on.
I actually have both a male and female end for flexibility but the male end (the one on the far left in the picture above) along with an extension is probably the one you’ll use 90% of the time to connect to another gas mask.
Open the valve and air is drawn through. By juggling the main inlet valve and the poppers-section valve you can change the concentration.
I use a little bit of hockey tape (the kind for shins, not sticks – incidentally this is perfect for sealing vac beds too as it doesn’t damage rubber) to improve the fit of the clear tube into the socket if I need to.
The same setup as for the poppers (20mm clear PVC flexible tube) works to push fit in a regular anaesthetic bag.
With the same hockey tape, I’ve found a nitrous cracker fits into the inlet valve quite nicely. In hindsight I would have added a valve to the main exhaust too, so that I could close everything, fill the rebreather bag with nitrous, attach my victim and then allow it out as I wanted.
40mm to 20mm conversion
You might want to go from 40mm (gas mask) to 20mm (standard anaesthetic). You can either do this using the rebreather bag setup, or I have a converter I found somewhere once but can no longer find.
If you have a very long hose between the setup and gas mask, be aware of tidal volume if you are rebreathing (i.e. the lung volume matches the total volume of all the tubes and so on).
(Tidal volume – the volume of air your lungs can breathe in and out without additional external force. )
Se7en note: The danger he refers to is this. Imagine you’re diving in the sea and breathing through a very long snorkel. That’s pretty much what you do artificially when constructing this. If the snorkel is too large, a.i. has a certain volume only a little smaller than your tidal volume, not all of your breathed out air makes it out the end of your snorkel to the surface, not all of it is exchanged. And when you breathe in again, you breathe in a portion of your already used air. That’s already dangerous, as generally already a portion of used air is always stored in our lungs anyways, and you might not get enough fresh one.
When the snorkels volume exceeds your tidal volume, no matter how hard you breathed out, your breathed out air could not reach the way up to the end of your snorkel at all. No air gets exchanged. You simply pushed it into the snorkel and stored it. And when you breathe in again, you simply rebreath your used air, and eventually get dizzy and suffocate through that.
The Tidal volume is, according to Wikipedia, approx. around 500 mL per inspiration or 7 mL/kg of body mass.
If you are unsure what your total manifold and hose volume is, you can calculate it with this tool)
I am deliberately not covering closed-circuits as that needs CO2 absorption, valves and other stuff that’s very complex and frankly dangerous.
Se7en note: He is right. You should not try anything complex or mechanical unless you are an expert. Even some engineers struggle with breathing apparatuses. It takes a lot to consider and a lot can go wrong, as this video concerning apparently not full experts constructing breathing machines for covid patients shows.
Lastly, please be careful when using this tool. Do test it out with a friend on each other in small steps, and make yourself a safety check list. Do not use it on somebody who’s regularly short of breath or has other health issues. Do not use it alone on yourself
