Method Kairos Kollar

[Talvikki]

Exit International presents a new method: Kairos Kollar. No further details known yet.

 

[Unbearable Mr. Bear]

Looks like a BDSM accessory. I like it already hahaha.

It may be interesting, but honestly I don't know what to think about this "Dr death" Nitschke. Is he a precursor or just a cynical businessman ?
And the "coming soon" is like you're waiting for a new movie. But thanks for sharing
One thing is sure : he's millionnaire and has all the nembutal he wants for him and his friends...
Am I jealous ? probably yes

 

[unluckysadness]

I hope they will talk about this method soon because I'm so bad and this collar could be interessant. In the photo we see the doctor in front of an audience, so why do they say "coming soon" ? The conference has already taken place. Why can't we find any Exit member here ?? I know they have their own forum but it's only for 50+ people.

I was looking at this the other day. It basically looks like bags are inflated and pressed against the carotid artery to cut off blood flow to the brain. Similar to a rear naked choke in jiu jitsu/mma. I imagine it feels like the device they when getting your blood pressure taken except around the neck. Getting enough pressure at the right spot seems like the biggest sticking point but it doesn't seem like it should be that hard.

I don't know what the inside of the device looks like, but if it wraps around the entire neck that is no bueno - then it's no different than other brute force methods like night night where pressure is applied to the entire neck.

This seems to be modeled after the KRA Cuff, where air bags are inflated at the sides of the neck. A right to die organization in Canada also developed something similar called the Fatal Faint collar - although much like the subject of the OP, there is no information out there about it, just a picture.

There is quite a bit of info out there about the KRA Cuff though.

Cool, I always wanted to look like some kind of alien.

Perhaps with a simple rope people can achieve the same result.

Yeah, the whole "coming soon" language around it is just so corporate-sounding. And yeah, fuck him, it's not like he's going to ever have to worry about finding a peaceful method should he ever want to CTB himself. He or his rich friends, investors, shareholders, etc. Exit International might be registered as non-profit itself but non-profits always find a way to actually profit through things like grants and contracts, skimming donations-with the added bonus that they don't have to pay taxes. They are great to launder money through as well.

But 1. I am always skeptical about this stuff and 2. I am probably just jealous too

Isn't that just a blood measure thingy but for the neck? Hmm, it does squeeze your arm very tightly

Sphygmamomometer <--- this thing

Recently I read a report about a young male who used sphygmomanometer to CTB. But some people have long necks and some short ones, so I don't think it will work well for everyone. But I might be wrong.

 

[navarro]

When do you think the Kairos collar will be ready?

 

[elenaboo25]

that looks uncomfortable

It's not really a new method, because back in 2018 Exit International already made a prototype of a collar using 3D-printing technology. The idea was that by tightening two plastic screws, pressure could gradually be applied to the neck until consciousness was lost due to lack of oxygen to the brain. In practice, though, the pressure couldn't build up fast enough to achieve the intended physiological effect, so the design wasn't developed any further.

Now they're working on an improved version. Part 1 is already included in the Peaceful Pill Handbook, and it's just a matter of waiting for Part 2 once the development is finished. When that will be, I honestly have no idea.


Once the Kairos collar is fully developed, it should be a simple device capable of applying the intended pressure.

The Kairos collar uses two inflatable balloons held in place above the baroreceptors. Once properly positioned, the balloons can be quickly inflated with compressed air up to approximately 70 kPa.

A T-shaped connection is used to quickly inflate both balloons simultaneously. Equal pressure is exerted on both within 0.1 seconds.

The Kairos collar takes advantage of several known physiological responses to rapidly reduce blood flow to the brain and thus reduce oxygen supply to the brain (cerebral hypoxia).

By simultaneously inducing a low heart rate through disruption of venous return and neural control pathways, blood flow to the brain via the carotid artery is restricted, thus simultaneously causing blood alkalosis (insufficiently acidic blood). This creates an ideal situation resulting in a peaceful and safe death.

Technically, the Kairos collar requires accurate location of the pressure points and rapid application of pressure. A positive aspect of the Kairos collar is that, unlike most other methods, it can be practiced beforehand.

With someone nearby, you can use the Kairos collar to inflate the balloons and then test whether you lose consciousness. Ten seconds of pressure can produce this effect. Consciousness can be quickly restored by quickly deflating the balloons. This ensures there are no adverse effects from such an exercise.

Applying pressure to the carotid arteries is also the basis of the popular judo choke hold. In judo, the opponent's arm is used in a "V" formation to apply pressure to the carotid arteries while the opponent's breathing remains unimpeded. A correct hold can cause fainting (syncope) within seconds.

The Kairos collar information is now available in the new version of the PPH. Exit claims it is

• simple, inexpensive & able to be made at home
• reliable & peaceful

If someone has a link on an PDF file, I'd be very curious to see this method in details. Unfortunately you must be over 50 to be a member, so impossible for me to download it.

 

[ethanfarnham]

Thought I'd add some pictures of the latest kollar, as well as what it is based on. It's frustrating how little information is online about this kind of device.

 

[Arvayn]

Kairos... They knew what they were doing with that name. I believe it means "a decisive moment in time".

 

[Talvikki]

The development is still ongoing

Before The Peaceful Pill Handbook publishes instructions on how to manufacture the collar yourself, testing is essential. This testing is currently being organized and is tentatively scheduled to take place in Switzerland—the only country with legislation that allows Exit International to produce the collar and then legally provide it to someone willing to participate in the trial.

The collar cannot be legally manufactured and sold; it must be a DIY (do-it-yourself) project. However, Exit International states that this won't be too difficult. There are no restricted components, and the collar can be stored until needed, as there are no shelf-life issues. If it's DIY, its use will be legal and unrestricted.

Details of the testing results will be shared as soon as they are available.

@Jello Biafra (formerly hell toupee) knows a thing or two about this

 

[unluckysadness]

Here is an interersting new article (in french) talking about the kairos collar

Il lance un collier qui permet une mort «en quelques secondes»

Un collier d'aide au suicide vient d'être créé. Derrière cette manœuvre se cache une lutte au sein d’un marché pas toujours guidé par des idéaux.

Will the Kairos Kollar actually happen?

Current status (as of late March 2026):

Philip Nitschke has demonstrated the Kairos Kollar multiple times on a mannequin during workshops in Australia, the Netherlands, London, and other locations.

In February 2026, he announced that a Dutch woman had volunteered as the first human test subject and that the initial real-person trial would take place in Switzerland. Nitschke described the device as "fast, reliable, drug-free, and importantly, unrestrictable."

However, as of the end of March 2026:

No confirmed human test or death using the Kairos Kollar has been publicly reported.

Exit's own communications state that the device is still in the testing phase.

Critics, including rival right-to-die organizations such as Pegasos and former Exit staff, have openly dismissed these announcements as PR stunts designed to generate revenue at a time when methods (such as Nembutal) are becoming increasingly difficult to obtain.

So, it does look like a bust/scam. Based on the article, it seems so too. It's inexpensive and DIY, yet, it uses AI for death. Doesn't sound DIY nor inexpensive. Smells of BS. If it were inexpensive and DIY then it would simply be a manual 'Night-Night' collar that we could secure in place and press.
