Abstract:
A non-invasive blood pressure measurement device comprising:a housing shaped to be gripped by a user to apply force toward the artery; a transducer having a sensing surface; a flexible diaphragm for being positioned over the underlying artery wherein the flexible diaphragm is mounted on a sensor assembly which is connected to the housing to pivot about at a position proximate the flexible diaphragm; interface means between the flexible diaphragm and the sensing surface of the transducer for transmitting pressure from the diaphragm to the transducer; signal producing means connected to the transducer for producing output signals corresponding to the sensed pressure data; and processing means for receiving the output signals from the signal producing means, for deriving a plurality of parameters using sensed pressure and for determining a blood pressure value using the derived parameters.
