OLGS is developing an automated tourniquet system. It is an intuitive device that works with the push of a button. The user only needs 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 places such as the ejector seat of combat aircraft and the first aid bags aboard cargo aircraft. Eventually all Battlefield Airmen, as well as all Joint Battlefield Forces can benefit from the availability of an easy-to-use tourniquet. Additionally, it can be located next to Automatic External Defibrillators (AED’s) within any Federal Building, or within Security Force vehicles on military installations.  We currently have a TRL 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 II proposal with the assistance of the University of Pittsburgh.  We will then begin developing TRL 7 devices tailor for the operating environments mentioned above.   Below are the Main Objectives of the project and the anticipated results.   Technical Objective Key Result Build and Test a Functional Prototype (TRL 6) Demonstrate Limb Occlusion Pressure of 300mmHg; Demonstrate software capability; Analysis of pressure distribution report Build Test Apparatus and develop testing methods for cadaver experiments Measure pressure on prototypes during development; measure pressure distribution; prepare for cadaver testing Develop requirements for three TRL 7 devices (various operating environments) Documented, professionally moderated discussions with KOL’s, SME’s, End-users; develop key features for various ATS’s; prepare concept sketches Validate material and electronics feasibility for ATS application Print metal inks on candidate belt material(s), incorporate pressure sensors; measure pressure on test platform; pressure indicator light Build ‘soft good’ and/or simulations of TRL 7 prototypes Deliver at least one virtual or ‘soft good’ prototype; review with 711th (BATMAN) and KOL’s; Deliver 3 of each if acceptable.   OLGS is also coordinating with the F-35 office.  The approach of developing the SmartTQ is in the spirit of the Digital Century Series philosophy, with advanced manufacturing capbilites being employed which will enable agile product development and manufacturing possibilities.  This effort is in line with EO 13329 'Encouraging Innovation in Manufacturing' Feb 2004.
