DARPA's DBAC device uses sound to stop bleeding

DARPA is always coming up with interesting new military technology that we just can't help but talk about. For instance, their new DBAC device could be used to save lives in the field. That's definitely pretty cool by us. 

DBAC stands for Deep Bleeder Acoustic Coagulation. This device is pretty much a wrap that can be placed around deep or internal wound areas and emits ultrasound. Doppler waves are used to find the wound and then once found, the frequency is cranked up to stop the bleeding.

All of this would happen automatically, so there'd be no need for fiddling around with a complex device in the field. This could seriously save lives and probably limbs as well in war zones. Call me impressed! A prototype should be ready in 18 months.
