Ars Technica link: Like science, but stupider: The XSTAT30.
It’s a wonder product that can almost instantaneously stop bleeding from gunshot wounds. It does not heal the wound, but it plugs it temporarily to avoid significant blood loss until the wound is treated. The device looks like a syringe full of tablet-sized sponges that expand after injection to the wound. Within 20 seconds, the expanded sponge then fills the cut, preventing blood loss and giving the patient a higher chance of survival. Each sponge last for up to four hours and absorbs up to a pint of blood. . . XSTAT 30 is manufactured by RevMedX, Inc., in Wilsonville, Oregon.
If the article got it right (which is far from certain given general and specialist media obtuseness) it's a wagonload of bullshit.
If it isn't cleared for use in "certain" parts of the chest, abdomen, and pelvis, WTF good is it? Jack and shit.
You're making a device that will be applied by 110-hr wondermedics with basic EMT certs, or at best by 6-month paramedics, and you're going to have them play "Do we or won't we?" games with the exact parts of the anatomy where tourniquets don't work?
Which have unhelpfully been blown open by bullets??
Total hype, hokum, and horseshit.
If you shoot that thing into a head wound, and it swells with blood collected, you've produced an unreduceable hematoma in the cranial vault. Stroke, and/or pushing the brains down through the spinal foramen (the hole at the bottom of the cranium where the brainstem lives and connects to the spinal column). The only more effective way to kill someone would be to pull their brains out with a crowbar and then stomp on it.
You can't put it into the chest, because it could tamponade the heart or major vessels, and they then have an unsolvable heart attack, or a hemothorax that a needle thoracotomy won't fix.
Ditto for the neck, where it could choke off blood flow to the brain, or block airways.
Put in inside the digestive tract, and you have a bowel obstruction that won't resolve. Ditto if it ends up in the bladder.
That eliminates 85% of the human body where it can't be used.
So when you eliminate the head, neck, chest, abdomen, and pelvis ("certain parts"?? I repeat, total horseshit) you're left with the arms and legs: IOW the exact places where the CAT and SOF-T tourniquets are expressly designed to shine, and have done for near 15 years. At one-third the list price!
And on an anatomical note, the sponges (92 of them) are designed to absorb "up to a pint of blood" each. So what they've designed is a device to exsanguinate the entire body at the speed of blood loss, since you only have 10-14 pints of blood in your entire body.
So as the blood flows out the holes and into the sponges, it is removed from circulation permanently, to form a cluster of clotted sponges full of blood, and your veins and arteries are sopped entirely dry. Rapid and profound shock, coma, and death result, in short and irreversible order.
Fucking genius, that. If you're a mortician looking for a handy way to prep the body for burial.
On the spectrum from Shineola to shit, this appears to be a truckload of the latter. An utter abortion, without legs.
Absolute best case: You might could use it on groin and armpit wounds.
If the bladder/lung isn't punctured. I suppose you'd need your handy field ultrasound machine to make that call. Which no one has, because it doesn't exist.
And if the wound's so bad you can tell they are punctured without your nonexistent field ultrasound machine, you can't use it. QED
So still worthless bullshit in search of a purpose. And government and institutional dollars.
While it clogs your kit with something of dubious, if not even non-existent, utility.
That thing's a CAT or Israeli bandage you didn't bring, both of which actually work.
And priced at the DoD friendly $100@.
"Mr. Shoddy: Dewey, Cheatham, & Howe are calling about patent infringement..."
I can think of where the makers could shove that thing, but I suspect they'd have to pry their heads out first.
Maybe in the new gender-bender military, it could find use as a field marital aid, and ad hoc birth control device.
"Introducing the SpermStopper 2000!"
That analysis is based purely on the article, but I can't imagine where you'd usefully shove it with the restrictions stated in the article, or how they expect field medics to utilize it under such recockulous restrictions under actual conditions. (I could suggest a place for the manufacturer to shove it, but you can probably guess that without further hints.)
If I hear or see more about it, and the maker has a better-than-the-Underpants-Gnome explanation of its function, utility, and restrictions that makes
