Title: NON-INVASIVE BLOOD PRESSURE MONITORING DEVICE AND METHOD
Abstract:
The present disclosure relates to a device and a method for blood pressure measurement, the device (12) comprising a pressurizing unit (30), that is arranged to supply, via at least one supply line (32), a wearable cuff (14) which is arranged to pressurize a measurement site (16) of a subject of interest, a pressure detection unit (40) that detects a cuff pressure (p2) in a direct or mediate fashion, a control section (50) comprising a feed forward 5 controller (64) arranged to output a target inflation flow signal based on a desired inflation rate (or pressure), a feedback controller (62) arranged to minimize the error between a target inflation rate (or pressure) and an actual inflation rate (or pressure), wherein the output of the feed forward controller (64) and the output of the feedback controller (62) are combined to drive the pressurizing unit (30), and a blood pressure determination unit (100) arranged to calculate a blood pressure value based on the cuff pressure (p2) detected by the pressure detection unit (40) during inflation when the cuff pressure (p2) is increased by the pressurizing unit (30) in accordance with a defined pressurizing regime.
