Throughout the history of modern warfare, countless wounded fighters have been saved from bleeding to death by tourniquets—the straps or ties that wrap around a damaged limb and staunch hemorrhaging.

But what if a soldier is shot through the pelvis, or in the armpit, where a tourniquet would be of no use?

Militaries the world over have grappled with the question for decades, and the issue took on new urgency during the US-led wars in Iraq and Afghanistan.

Now the US Army has found an answer.

The service currently is training and equipping its combat medics with a new device, called a junctional tourniquet.

It looks a bit like a belt, but comes with two inflatable bladders that can be pumped up to put pressure over a wound, even in locations where a traditional tourniquet would be ineffective.

“Exsanguination (bleeding to death) is the most common cause of potentially survivable death for wounded warfighters,” said Ellen Crown, a spokeswoman for the US Army Medical Materiel Agency.

The junctional tourniquet is designed so “a person can position it in under a minute—a crucial factor for combat medics who only have mere minutes to save a fellow warfighter’s life if he or she is hemorrhaging.”

The first recorded combat use of a junctional tourniquet was in Afghanistan in 2014, when US and Afghan medics saved a young Afghan National Army soldier who had been shot by insurgents.
