Ultrasound can be used to treat internal bleeding in wounded soldiers without surgery
The device would first use ultrasound imaging technology, in particular “Doppler ultrasound”, to locate internal bleeding. This employs a physical phenomenon known as the Doppler effect to look for a characteristic signature of bleeding vessels.
It would then deliver a focused beam of high-powered ultrasound to those sites in order to cauterise the damaged vessels.
The Deep Bleeder Acoustic Coagulation (DBAC) programme is sponsored by the US Defense Advanced Research Projects Agency (Darpa).
Darpa envisages the device as a “cuff” containing an array of ultrasound transducers, different elements of which will detect bleeding and deliver focused, high-powered energy to the wound. This cuff would be flexible enough to be wrapped around the treatment area.
