Ultrasound cuff to stop internal bleeding on battlefield

As we all know much of the technology developed by DARPA makes its way into healthcare outside the military as well. It is not ready for prime time yet and they expect a mock up to be used in 18 months, but would this not be a valuable tool anywhere, in the ER to stop internal bleeding after an accident. BD

Internal bleeding can cause irreversible haemorrhagic shock within 30 seconds or progressive shock within eight hours, either way, it's not good and the military wants a portable, noninvasive way to detect and stop it right on the battlefield.

To that end, the Defense Advance Research Projects Agency (DARPA) has contracted with Siemens Healthcare, the University of Washington's Centre for Industrial and Medical Ultrasound and Texas A&M to develop something called the Deep Bleeder Acoustic Coagulation cuff (DBAC). The cuff is a semi-automated, ultrasound device designed to cut blood loss and shock resulting from combat limb injuries, one that can be operated by any GI with minimal training.

A medic applies the cuff to the injured limb, the DBAC automatically locates the bleeding and triggers a dose of high-intensity, focused ultrasound toward it, this prompts quick coagulation and an end to the bleeding.
