This Device Stops the Bleeding From a Gunshot Wound in 15-Seconds

Developed by a small startup called RevMedX located out of Oregon, the XStat which is a modified sponge-filled syringe is able to stop the bleeding of a gunshot wound in 15-seconds. "By the time you put a bandage over the wound, the bleeding has already stopped." Simple and innovative, the XStat would literally be a lifesaver with a soldier on the battlefield as well as an officer in the city. 

Learn more and see how it works below: 

The device houses numerous 1-centimeter circular sponges within a 30 millimeter-diameter, polycarbonate syringe-like body. Each of the individual sponges are marked with an 'X' to make them visible to X-rays (so none are accidentally left within the body) and each expands when in contact with blood to fill the void and apply adequate pressure to the wound. The medic simply inserts the cylinder end into the gunshot wound and then injects the sponges. The innovative prototype got attention from the U.S. Army who gave the team $5-million to develop and finish the product. 

The sponges work fast: In just 15 seconds, they expand to fill the entire wound cavity, creating enough pressure to stop heavy bleeding. And because the sponges cling to moist surfaces, they aren't pushed back out of the body by gushing blood. "By the time you even put a bandage over the wound, the bleeding has already stopped," Steinbaugh (former U.S. Army Special Operations medic) says. 
The design has a slim profile and would eliminate the need for a field medic to carry bulky rolls of gauze. As the XStat is developed further, the team wishes to upgrade the design with biodegradable sponges that don't have to be removed. They plan on having a smaller applicator version for smaller injuries and for larger wounds (caused by land mines) expandable gauzes that are made from the same XStat sponges.
