Automated Tourniquet

OLGS is developing an automated tourniquet system. It is an intuitive device that works with the push of a button. The user only need to know 'high-and-tight' and push the button for the tourniquet to be effective. It contains a band with wires embedded that is tightened by a motor-driven spool. It also contains a micro-controller unit with integrated sensors to ensure limb occlusion pressure is achieved with minimal risk of nerve damage from over-tightening. Discussions with PJ's have already informed some design characteristics to make the device easier to operate. The device will be integrated into the ejector seat of combat aircraft and the first aid bags aboard cargo aircraft, with the end user being survivors of downed aircraft. Eventually all Battlefield Airmen, as well as all Joint Battlefield Forces can benefit from the availability of an easy-to-use tourniquet. We currently have a TRL 4-5 device, and have the hardware, firmware, and mechanical design for a functional prototype that will be TRL 6 (demonstrated ability to achieve limb occlusion pressure) by the end of this Phase I proposal with the assistance of the University of Pittsburgh.
