Novel interface pressure transducers for tourniquets and other medical devices.

Abstract

Novel MEMS transducers have been developed and tested for the measurement of interface pressure in biomedical tourniquet applications. On-body transducer performance was evaluated by reference to tourniquet inflation pressure for pneumatic tourniquets. Excellent correlation between transducer indicated peak pressure and tourniquet inflation pressure was observed. In addition, the transducer, in the form of an array, provides real-time pressure-gradient data. Transducer performance with non-pneumatic tourniquets was also evaluated.
