AcousTx' portable ultrasound device finds and heals internal bleeds:

This article was originally published in Clinica

Executive Summary

US firm AcousTx is developing for use by the military a portable, automated ultrasonic cuff that will be able to locate sites of internal bleeding and then coagulate them in emergency situations. The device, for use by untrained soldiers on the battlefield, aims to stop bleeding quickly, in order to prevent the onset of progressive shock, "when a soldier loses 25% of his or her blood volume", said the firm. The cuff contains "multiple ultrasound transducer subarrays" that are wrapped around the treatment area. The device then scans the area for the internal bleed using a Doppler signal. Once located, high intensity ultrasound is used to coagulate it. AcousTx, based in Seattle, Washington, is a spin-out of ultrasound company Therus.
