Problems solved by technology

However, this measurement method needs to hold a mobile phone, and it cannot be measured under certain conditions (such as when driving a vehicle)
However, the existing image blood pressure measurement method only uses the time difference between finger and facial pulse peak signal as the pulse transit time feature, so the accuracy of blood pressure measurement in actual implementation cannot achieve the ideal result

Embodiment Construction

[0025] see figure 1 , which is a functional block diagram of the blood pressure measurement system 1 of the embodiment of the present invention. The blood pressure measurement system 1 is used to implement the method for evaluating the systolic blood pressure and the diastolic blood pressure of the subject, and includes a processing module 14 , an image capture module 13 , and a storage module 12 . The processing module 14 is coupled to the image capture module 13 and the storage module 12 for processing the image output by the image capture module 13 .

[0026] The storage module 12 stores a variety of known learning sample features, such as the regression prediction model #1~regression prediction model trained by K-nearest neighbors learning and artificial neural network algorithm Prediction Model #N, but not limited to. The plurality of regression prediction models include a body mass index (body mass index, BMI) prediction model and a systolic blood pressure and diastoli...

Abstract

A image blood pressure measuring method for a blood pressure detection system is disclosed. The blood pressure detecting system includes a processing module and an image capturing module configured tocontinuously records a hand and a face of a subject to retrieve multiple hand and face images associated with the subject. The method includes, by the processing module, obtaining biological information related to blood pressure of the subject according to the multiple hand and face images retrieved by the image capturing module; and, by the processing module, obtaining prediction results of systolic and diastolic blood pressures of the subject according to the biological information related to blood pressure of the subject.

Description

【Technical field】 [0001] The invention relates to an image-type blood pressure measurement method, in particular to an image-type blood pressure measurement method using image-type pulse wave time difference. 【Background technique】 [0002] Most of the existing video blood pressure measuring devices measure the finger and face pulse wave signals of the subject simultaneously through the front lens and the rear lens, and compare the time difference of the pulse wave through the two signals. However, this measurement method needs to hold a mobile phone, and it cannot be measured under certain conditions (such as when driving a vehicle). However, the existing video blood pressure measurement method only uses the time difference between finger and facial pulse peak signals as the pulse transit time feature, so the accuracy of blood pressure measurement in actual implementation cannot achieve the ideal result. [0003] In view of this, how to improve the accuracy of blood pressu...
