Charles River Analytics Inc., developer of intelligent systems solutions, has received additional funding to develop its Tourniquet Master Training (TMT) system. TMT provides training on tourniquet technology to Warfighters who treat injuries on the battlefield. The two-and-a-half-year contract was awarded by the US Army Medical Research and Materiel Command with a value of $1 million. Charles River’s partners on TMT include the University of Wisconsin, Boston Engineering, and Compression Works LLC.

Most Warfighters who die from combat wounds do so before they arrive at a medical treatment facility, highlighting the importance of trauma care on the battlefield. Recent lifesaving advances in battlefield medical treatments have dramatically increased casualty survival. This is especially true when medics receive state-of-the art training to accompany rapid advances in medicine.

For example, some injuries cannot be treated by traditional tourniquets or gauzes, such as those in junctional areas, including the abdomen or pelvis. New types of junctional tourniquets have been developed to treat these types of injuries, but technology to train medical personnel on how to apply them is limited.

To fill this gap, Charles River is developing the TMT system to teach, assess, and provide refresher training on these new tourniquets, such as the Abdominal Aortic Junctional Tourniquet™ (AAJT), the Junctional Emergency Treatment Tool™ (JETT), the Combat Ready Clamp™ (CRoC), and the SAM® Junctional Tourniquet (SJT). TMT addresses a critical need in lifesaving training—because these types of injuries are rare, there are few opportunities for practice.

“TMT lets medical personnel practice using junctional tourniquets and get objective feedback on their performance,” explained Benjamin Bauchwitz, Technical Lead on the TMT effort at Charles River. “This training is key for challenging battlefield environments, where correct use of these tourniquets could stop combat-related deaths.”
