Expandable sponges could fill gunshot wounds in 15 seconds.
Current emergency treatments for combat wounds on the battlefield have little to show for the gravity of the situation, a process that may or may not be effective depending on the size of the injury. Packing gauze bandages into the wound cavity has been the procedural approach, but RevMedz developed a replacement that could offer faster and more efficient results.
The XStat is a modified syringe that injects specially coated sponges into wounds, which can fill the entire cavity in just 15 seconds. Endorsed by the U.S. Army, this invention uses sterile, biocompatible and fast-expanding materials to better accommodate unpredictable conditions.
The sponges are made from wood pulp and coated with chitosan, a coagulant that comes from shrimp shells. X-shaped markers are stamped on each sponge so that it can show up on an x-ray image in case any remnants are left inside the body. Once injected, these sponges will cling to the surfaces of the wound and create enough pressure to stop heaving bleeding.“By the time you even put a bandage over the wound, the bleeding has already stopped,” says John Steinbaugh, former U.S. Army Special Operations medic.
In thinking of a way to easily deposit the sponges into a wound, the team partnered with Ziba, a Portland-based company, to design a 30 millimeter-diameter polycarbonate syringe. A smaller version, with a diameter of 12 millimeters, was designed for narrower injuries.
Once the FDA grants approval, the XStat could become a valuable emergency treatment unit for deployed soldiers, boosting survival rates among seriously injured individuals. Each applicator will likely cost about $100, but price is expected to go drop, as demand increases.
