Human pulse wave velocity measuring method and system based on intelligent mobile phone

Abstract

The invention relates to a human pulse wave velocity measuring method and system based on an intelligent mobile phone. The method includes the steps that human cardiac physical signals are collected through the mobile phone; human finger video signals are collected through the mobile phone; filtering processing is conducted on the human cardiac physical signals, and cardiac change timing signals are extracted; the human finger video signals are processed, and finger pulse change timing signals are extracted; multiple dimensions, such as frequency, wavelength, wave amplitude, peak value and velocity of the two groups of signals are analyzed in a comparative mode; associated change points are calculated, and the pulse wave velocity is calculated through the time difference of the associated change points. The human pulse wave velocity measuring method and system have the advantages that the cost is low, and measurement is comprehensive, accurate and simple; a user can conduct measurement with the existing intelligent mobile phone at any time and in any place without professionals, cerebrovascular diseases are found out in time easily, seeking medical device is conducted in time, and great social value is obtained.

Description

technical field [0001] The invention belongs to the pulse wave velocity measurement technology, and in particular relates to a human body pulse wave velocity measurement method and system based on a smart phone. Background technique [0002] Given that Pulse wave velocity is an independent predictor of cardiovascular disease risk, reducing PWV is a therapeutic goal, especially when treating elderly hypertensive patients; continuous PWV information not only plays a key role in treatment , In addition, PWV measurement is also of great value for healthy people to prevent cardiovascular and cerebrovascular diseases. Traditional PWV measurement methods mostly use ultrasonic sensors, pressure sensors or electric pulse sensors. On the one hand, the hardware cost is high and the equipment is inconvenient to carry. [0003] In addition, people's pulse wave velocity is not constant in different seasons, and it also changes slightly with age, especially for cardiovascular and cerebrov...
