AAT tourniquet

Charles River Analytics (CRA) has been awarded a contract to provide Tourniquet Master Training (TMT) to US Army medics for effective treatment of injured soldiers in the battlefield.

Awarded by the US Army Medical Research Acquisition Activity (USAMRAA), the contract requires the company to design and demonstrate a TMT system to teach, assess and provide refresher training to medics and first responders on the combat ready clamp (CRoC) and the abdominal aortic tourniquet (AAT) systems.

Charles River principal scientist Dr. Peter Weyhrauch said the TMT enables trainees to work with new tourniquet technology in a scenario-based training system, which is critical due to the rare occurrence of these injuries.

”TMT includes a manikin equipped with sensors and linked to a virtual mentor that helps guide trainees on using the new technology, provides feedback and later refreshes those skills," Weyhrauch said.

CroC and AAT are specialised tourniquets types, designed for effective treatment of the abdomen or pelvic injuries, which cannot be treated by conventional tourniquets or gauzes.

"AAT is a tourniquet for wounds sustained in the pelvis or upper leg due to gunshot, shrapnel or a blast."

Manufactured by Compression Works, AAT is a US Food and Drug Administration-approved tourniquet for application on wounds sustained in the pelvis or upper leg due to gunshot, shrapnel or a blast, and which may potentially bleed a person to death within minutes.

CRoC is lightweight, durable, collapsible tourniquet designed to stop bleeding in umbilicus/inguinal and axilla regions where conventional tourniquets and haemorrhage control methods cannot be applied.

Performance period and cost of the contract, which is managed by the Telemedicine and Advanced Technology Research Center’s Medical Simulation & Training Technologies team, remained undisclosed.
