BLOOD-PRESSURE CONTINUOUS-MEASUREMENT DEVICE, MEASUREMENT MODEL ESTABLISHMENT METHOD, AND SYSTEM

摘要

A blood-pressure continuous-measurement device, a measurement model establishment method, and a system. The device comprises: a signal collector (100), used for collecting electrocardiosignals and pulse wave signals of a measured object for multiple consecutive cardiac cycles, so as to obtain two sets of synchronous electrocardiosignals and pulse wave signals; a signal reception module (210), used for receiving the two sets of synchronous electrocardiosignals and pulse wave signals; and a blood pressure computing module (220), used for extracting a first characteristic point of the pulse wave signals according to the two sets of synchronous electrocardiosignals and pulse wave signals, extracting a second characteristic point of the electrocardiosignals in a same cardiac cycle according to the first characteristic point, acquiring corresponding characteristic values according to the first characteristic point and the second characteristic point, selecting a characteristic parameter from the characteristic values according to an evaluation parameter, and acquiring a blood pressure value according to a pre-established blood pressure computing model of characteristic parameters. The device, the method and the system have the characteristics of high precision, low complexity, low cost, convenience in measurement, and high real-time quality.
