Unless you have the instruction manual taped to your chest, I don't see any non-track EMT's using this thing.

Interesting. If i am not mistaken paramedics/emt's are trained to properly remove a helmet anyway.

Hmmmmmm, not in my experience.

This might be something I'd want to have at the track available for EMS to use if need be... thanks!

Seems interesting.

mitaken. most are not.

Public Service Announcement - if you have old hemets that you're no longer using - even crashed helmets, donate them to the fire dept. or hospital for helmet removal training!!!!

Some EMT's/Paramedics are trained, most are not.

[wildchild]

looks like an interesting system.

BTW lauralynne, great idea about donating, wish i had thought of that, as over the years i have tossed a number of helmets.

[karl_1052]

Is it a one use system?

Cause that would be sweet to raise and lower, while cruising in my flip flops on my stretched, chromed Air Jordan GSXR.

I thought you might like it.

I'm still on the fence. It seems to me that the pressure of a well fitting helmet, would cause the balloon thingy, to exert force DOWN the spine, compressing it, which I believe is a bad thing.

I'd like to see more medical data.

Looks interesting to me. I would think since it is using the top of the head as the push point, it wouldn't put any pressure on the neck or spine. Ripping your ears and the tip of your nose off maybe, but guess if you can't breath that would be minor.
And it could be drunken party fun to use compressed air and shoot for distance.

if a person suffered a compression fracture in the neck a device like that could cause problems because of the downward pressure so in some cases it could be a problem.

It looks like the downward pressure would only be on the top of the head. The actual pressure would be on the helmet lifting. You gotta hope they remember to remove the chin strap first. :)

I hate it when I do a movie quote and the person doesnt get it.

I was playing L4D2 and a guy was joining in with the name, McLovin. I said, "McLovin. That's a dumb fuck name" and the guy goes off like a kid getting his halo taken away. :lol Guess this one is a bigger fail since they guy should have know what I was saying.

Exact same. My roommate and I will randomly just start quoting movies to see who can come up with the most from one movie.

If you push down on your head with your hand, sure, it'll put pressure on your neck...

but if you put an expanding force between the top of your head & the inside of the helmet, no force will be transfered down to your neck... only the top of your head & your cheeks as the helmet lifts off & they're in equal & opposite directions, canceling each other out.

Two negatives = a positive?

[OreoGaborio]

Haha, well in this case, two wrongs do make right. :p

The system lifts the helmet, while keeping the head in place... so in theory it shouldn't put any pressure on the spinal column.

Opposite, yes.

Equal, I'm not so sure. Unless you know the value of the helmet's resistance, vs. the downwards force of the bladder, equality can not be determined, and your hypothesis can not be proved.

So there. :lol:

I believe they offer an online course for EMT's. If it's free, I'll go take it and report back.

JC

[OreoGaborio]

The sum of the force transmitted past the cheekpads/head and onto the spinal column is only equal to the force it takes to accelerate the helmet to the speed at which it's moving off of the head...

So if the helmet maintains a steady speed, the forces are equal and opposite and no force is transmitted onto the spinal column.



If you wanted to simulate this, you could take three blocks or something... one representing the helmet, another representing the head and a third representing the body, put them all down on a surface like a sheet of ice & pretend it's zero friction.

Then, put something between the head & body that measured the force between them (which would tell you how much force is being put on the spinal column), and an expanding bladder between the helmet & head and slowly inflated it. That force measuring device would hardly register a thing.

Now put something on the helmet and head that creates drag between the two (like the cheekpads) and all of the force from the bladder would be spent on separating the two.

The only thing that would move in those two instances would be the helmet. The body would hardly move at all because virtually zero force is transfering past the head.



Anyway, I could be totally wrong, but that's just how I see it.... I used to be a total physics geek way back in highschool when we did this kinda stuff :p

You don't say...:lol:

Your physics are correct if the helmet is free to do what it wants, but it's my understanding that the helmet should be kept from rolling around when it's being removed. The added resistance of somebody holding it, is what I'm wondering about.

I suspect it's a matter of technique.

I'm not saying the thing is good or bad. I've just seen a lot of gizmos come and go over the years, that were designed by good intentioned riders, rather that doctors who actually (allegedly) know what the hell they're doing.

For the record, my plan would be to tell the EMT's to leave my helmet on, till I got to the hospital.

Unless of course I wasn't breathing, (in which case I wouldn't be talking anyway).

thats about the only time I would consider removing the helmet of an injured rider I came upon in the field.

[askmrjesus]

OK, so I went and took the online course for EMT's.

Yeah, I lied, so what?

Anyway, after taking the course, and watching the thing in action, I've decided this thing gets the AMJ Seal of Approval.

There were some good endorsements from a doctor who seemed to know what he was talking about.

I'm going to buy the "Non-installed" version, cause I'm all about sharing.

I don't plan to use it on my own, since I don't ride around with a back board and a C collar, but I will have it handy for EMT's to use, if they need to establish an airway.

Otherwise, I'm still opting for "leave my shit alone till we get there".

Oh, for you non-believers....:lol:

Did the computer automatically blank out Jesus H Christ? Wow, it must have the fear of God in it.

[CrazyKell]

I'm not convinced. don't you have to kind of tilt the helmet to get it past the occipital area? If it just moves it straight off, I don't think it would really work. :idk:

[askmrjesus]

Yes.

This is a two person operation.

Basically, after removing the chin strap, and glasses/goggles/debris, one person holds the head and neck steady, by reaching up into the helmet on either side of the face, cradling the C-Spine with their fingers. This is absolutely critical.

The second person inflates the bladder, while guiding the helmet off, tilting back slightly, so the riders' nose clears the chin bar.

Ideally, a third person would handle the inflation duties, so the helmet remover could concentrate on their job, with both hands.
