A biotech company is developing an “ultrasonic tourniquet” that could be used to quickly staunch bleeding for soldiers in the battlefield. The company, Siemans Healthcare, announced that it has won a contract with the U.S. Defense Advanced Research Projects Agency (DARPA), which hopes to have a prototype of the device in hand within 18 months.
The hope is that the device, known as the Deep Bleeder Acoustic Coagulation cuff (or DBAC), will be able to non-invasively clot blood vessels and stop internal bleeding from combat limb injuries – the leading preventable cause of death of soldiers in action. Longer term, Siemens believes the technology will also find applications in civilian care [Medical Physics Web].
