A biomedical interface pressure transducer which is useful for interposing between a limb or tissue and an occlusive band, tourniquet cuff or other biomedical apparatus in order to estimate the pressure and pressure gradient applied to a selected area of the limb or tissue is disclosed. The pressure transducer comprises a modified MEMS pressure sensor and a conformable semisolid body enclosed in a shear relief membrane which translates the pressure applied by the occlusive band to the modified MEMS pressure sensor mounted on a flexible substrate with patterned electrical interconnect tracks allowing the connection of the pressure sensor to digital communication and control circuitry.

Biomedical interface pressure transducer for medical tourniquets

A planar pressure transducer is disclosed which is useful for interposing between living tissue and a medical device that applies pressure to the tissue in order to estimate the pressure applied to a selected area of the tissue. The planar pressure transducer comprises a pair of opposed plates between which the proximal ends of optical fibers and a deformable polymer structure are disposed. When the plates are subjected to a pressure acting normally to the plane of the plates an optical signal is obtained via the distal ends of the fibers and related to the pressure acting on the plates.
