Charles River Analytics Develops Tourniquet Training System for Department of Defense

Charles River Analytics, a developer of intelligent systems solutions, announces a follow-on contract award for Tourniquet Master Training, or TMT. TMT aims to aid warfighters treating injuries on the battlefield by providing training on tourniquet technology. The contract was awarded by the US Army Medical Research Acquisition Activity with a value close to $1 million over a twenty-nine month period.


AATBattlefield medical treatments have progressed significantly in recent years and quick and proper use of tourniquets has saved many lives. Unfortunately, some injuries cannot be treated by traditional tourniquets or gauzes, such as those in the abdomen or pelvic areas. New types of junctional tourniquets have been developed to treat these types of injuries, but systems have not been developed to train medical personnel on how to apply them. Charles River Analytics is developing TMT to teach, assess, and provide refresher training on this new tourniquet technology, including the Combat Ready Clamp™ (CRoC), the Abdominal Aortic Junctional Tourniquet™ (AAJT) as seen in the figure, the Junctional Emergency Treatment Tool (JETT™), and the SAM® Junctional Tourniquet.

“TMT is a scenario-based training system that allows trainees to work with new tourniquet technology,” explained Dr. Peter Weyhrauch, Principal Investigator on the TMT effort at Charles River. “This training is critical since these injuries are uncommon, resulting in few opportunities to practice treating them. TMT includes a sensor-based system linked to a software-based virtual mentor that provides initial assessment and feedback during training, as well as a mobile mentor that provides refresher training. It is usable with multiple manikins and configurable for future tourniquet technology advances.”

“We are pleased to continue development of TMT for the Department of Defense,” Dr. Weyhrauch continued. “It provides an affordable system to improve tourniquet training, which can save lives in challenging battlefield environments. Tactical Emergency Medical Support providers can also benefit from TMT as the use of advanced tourniquets spreads to non-military organizations, such as the FBI, SWAT teams, and the Department of Homeland Security.”

TMT is one of Charles River’s efforts in medical support and training; other efforts include:

  • Laparoscopic Surgery Training System (LASTS) – a system to help military surgeons returning from deployment to refresh their laparoscopic surgery (LS) skills. Surgeons efficiently refresh their laparoscopic surgery (LS) skills through training systems and courses that improve effectiveness and retention.
  • Mobile, Virtual Enhancements for Rehabilitation system (MOVER) – enhances outpatient rehabilitation with engaging video games, a mobile app, sensors, and virtual coaches.
  • Remote Exercises for Learning Anger and Excitation Management (RELAX) – a handheld device application to manage anger and stress, accessible on iOS mobile devices, such as the iPad and iPhone.
