Preventing Fatal Blood Loss with Injectable Foam

In a combat situation, a wounded soldier can bleed to death quickly without prompt attention. But depending on where the injury is, like a deep wound at the neck, shoulder, or groin, traditional treatments, such as tourniquets, may not be able to staunch the blood loss. So, engineering students at Johns Hopkins University, Baltimore, MD, invented an injectable foam system designed to quickly stop this type of profuse bleeding. The invention is designed to apply pressure and curb blood loss during the critical first hour during which a wounded soldier can be moved to a site for more advanced medical help.
