Following the debut of an amazing new shapeshifting material that could improve drug delivery, military-tech wing DARPA has unveiled this equally impressive polymer foam. Just inject two liquids where a soldier is bleeding, and the chemicals react, creating a foam that presses against an internal wound and stanches the flow of blood. That buys at least a precious hour to find medical care.
About 85 percent of preventable battlefield deaths are from internal wounds that need surgery or other in-hospital treatment. There's often just not enough time to transport a soldier from a firefight to a place where they can get the right medical attention. But during testing on pigs, DARPA says the foam increased the chances of survival after three hours from 8 percent to 72 percent, and surgeons removing the foam could do it in less than one minute.
Arsenal Medical, the company that received funding from DARPA to research the foam, says it's working on a version for civilian use while DARPA is looking for FDA approval. Hopefully we'll see it soon--and not need it.

The Halo series had it right. Presenting: Bio-foam
Yeah I always wondered why nobody tried making actual Bio-foam from halo before. It seemed like a realistic way to stop people from bleeding out, preventing infection, and keeping guts inside the body. Heres hoping this stuff works as well as it does in fiction.
Couldn't this cause something similar to a tension hemopneumothorax? The foam expanding and pressing on the diaphragm, increasing thoracic pressure and essentially squeezing the heart, can't be a good thing.
More info please!
Also, did anyone else notice the size of that damn needle!? That thing was the same gauge as a turkey baster!
I have a Celox applicator and an extra 35g pouch for puncture wounds such as the one mentioned in the video.
My that looks painful... I can only imaging the terror of feeling something expanding under your skin, separating the skin from the rest of the tissue around it. I see a new form of torture!
For the ill and dying, petrifaction with the hopes of preservation of the remaining life form.
And if the patient dies, we are half way home preservation.
WoW, it almost seems cost effective to save a life and burry one too. ;)
Great. Magic Foam...
Maybe Billy Mays could have cured himself of his drug induced heart attack if Magic Foam had been invented years ago.
It looks scary, but the times it's needed are even scarier.
You KNOW that you're going to die quickly if you bleed out.
You MIGHT sufer damage or even death from this stuff.
I suspect that a lot of emergency procedures are risky.
Being shot and having the choice between instantly bleeding to death or surviving for some more hours I think the side actions of this material are neglectible. But for the US please print onto the device: "Do not inject intravenous or into respiratory pathways".
Considering the life saving potential on shot pigs was a 7% to 72% increase - any risk involved is negligible. It saves so many more than it kills that it is worth doing (like seatbelts).
Someone did this a few years back. You shoot the foam into the blood vessel which leads to the heart then "quickly" sew the vessel to the heart. Within a few minutes the foam melts and you are back to normal. The foam acted as a clamp or dam of sorts. Didn't they do something like this on Firefly too?
@beantown179
I think it was "Serenity", the movie follow-on to Firefly.
However, the concept has been around for several decades at least. Even I immediately saw the potential in something like this when I first used self-expanding insulation foam many years ago.
I see no reason why this can't be used almost immediately. The injuries we are talking about WILL kill within minutes if nothing is done to stop the bleeding. Possible complications can be dealt with once the person is in the emergency room.
Why the FDA has to rigorously test a product that is already KNOWN to SIGNIFICANTLY improve an animal's survival rate from severe trauma is mystifying to me. If I saw even one animal come away alive from a life-threatening injury because of this foam, that would be enough for me.
My head went immediately to avenues echoed by some on the thread, but as always, one step further. One step, where angels dare not. Weaponizing a bit of this stuff, suitable for a human torso, via a ventilated slug that both aerates the compound and punches an entry point.
This is stolen from Halo! Full rights to Bungie, or Microsoft now, I think.
