    How To Seal A Gunshot Wound In 15 Seconds

    A new sealant can stop the bleeding from serious gunshots almost instantly, its makers say.

    Getting shot is a fact of warfare - but being killed from a bullet wound isn't. A new experimental sealant claims to be able to stop the bleeding from a gunshot wound in 15 seconds.

    Arterial bleeding is the main cause of death among soldiers and patching someone up in the thick of things isn't easy. Currently, battlefield medics pack gauze sometimes as deep as five inches into the body to stop the bleeding. It's a painful business.

    Now RevMedX, a military medicine company - short for Revolutionary medical Technology - has developed a pocket-sized invention it claims can inject sponge directly into wounds and seal it straight away.

    The XStat's makers were inspired by the expanding foam used to fix tyres and other things.

    But a spray like that wouldn't work - it wouldn't soak up enough blood. So the RevMedX team tried something else: sponges.

    The team experimented with normal sponges cut into 1cm squares on animal wounds and were immediately impressed. “The bleeding stopped. Our eyes lit up. We knew we were onto something," says John Steinbaugh, a former U.S. Army Special Operations medic who now works with RevMedX.

    "By the time you even put a bandage over the wound, the bleeding has already stopped," claims Steinbaugh.

    The XStat contains rapidly-expanding sponges that create a barrier to stop bleeding. The manufacturer claims no pressure needs to be applied.

    The sponges are made from wood pulp and are coated with chitosan, an antibacterial substance used in wine making that comes from shrimp shells. The syringes are tiny - either 30mm or 12mm diameter - and would replace five rolls of gauze in a soldier's kit. Each one would set the army back $100.

    The XStat is still seeking approval from the U.S. Federal Food and Drug Administration, although the product has the backing of the army, which requested its approval and has gave the company $5 million to develop its prototypes.
