Research & Technology
ATLAS TQ is an automated, microcontroller-driven tourniquet system designed to improve life-saving hemorrhage control in the field.
Developed to address the limitations of manual windlass tourniquets, ATLAS TQ leverages a precision motorized mechanism to deliver consistent, rapid occlusion of blood flow — even when deployed under stress or in difficult conditions.
Its compact design integrates a calibrated tension band, a drive motor, and closed-loop feedback control to ensure optimal performance across a range of users and limb anatomies.
ATLAS TQ enables single-handed operation, faster application times, and greater reliability compared to traditional manual systems.
How ATLAS TQ Occludes Blood Flow
The ATLAS TQ system uses a closed-loop motorized tightening mechanism to achieve rapid, reliable blood flow occlusion:
