Abstract
A non-invasive blood pressure measurement device is used for determining blood pressure of an artery. The device comprises a housing unit, a base unit and a sensing unit. The base unit is pivotally connected to the housing unit and comprises electrical circuitry, a flexible ring, and a receptacle. The sensing unit comprises a pressure transducer for sensing pulses of the underlying artery, the transducer having a sensing surface, a flexible diaphragm having an active portion for transmitting blood pressure pulses of the underlying artery, interface means coupled between the sensing surface of the transducer and the flexible diaphragm for transmitting the blood pressure pulses within the underlying artery from the flexible diaphragm to the sensing surface of the transducer, a compressible ring, and connection means for detachably connecting the sensing unit to the receptacle of the base unit.
