BCG-SIGNAL-BASED MULTI-SENSOR BLOOD PRESSURE MONITORING APPARATUS AND METHOD

摘要

A BCG-signal-based multi-sensor blood pressure monitoring apparatus, comprising: a BCG signal collection module provided with a plurality of sensing points and used for collecting BCG signals of a plurality of parts of a body, wherein the BCG signal collection module comprises sensors (11, 12) distributed at a plurality of points; a signal processing module for filtering and amplifying the BCG signals, determining the validity of the BCG signals and extracting BCG signal characteristics, wherein the signal processing module comprises a signal filtering and amplifying unit (21) and a BCG signal characteristic extraction module (22); and a blood pressure calculation module (23) for calculating a blood pressure value of a user. The blood pressure monitoring apparatus has the advantages of a high blood pressure measurement accuracy, the capability to continuously monitor a blood pressure, non-contact operation and low monitoring costs, and is more applicable to real-time monitoring of heart functions in daily life.
