Embodiment Construction

[0026] The smart heart rate earphones described in this application respectively obtain the photoplethysmography waves of the user's ears and the photoplethysmography waves of other parts of the user, and transmit the photoplethysmography waves to the processor in real time and synchronously. The processor obtains the transmission time of the pulse wave according to the photoplethysmography wave of the user's ear and the photoplethysmography wave of other parts of the user, and calculates it to obtain the blood pressure value of the user. Therefore, the photoplethysmography signal-to-noise ratio of the user's ears monitored by the application is higher than that of the user's parts such as the wrist, which improves the accuracy of monitoring the user's blood pressure value. Moreover, the application monitors the blood pressure value of the user through the smart heart rate earphone and the smart portable terminal, which is easy to wear and easy to operate.

Abstract

A blood pressure measurement method, intelligent heart rate monitor earphone (1), and system. Each earbud of the intelligent heart rate monitor earphone (1) is integrated with at least one heart ratemonitor chip, and the intelligent hear rate monitor earphone (1) communicates with an intelligent portable terminal (2). The method comprises: acquiring, by means of the intelligent heart rate monitorearphone (1), a photoplethysmographic pulse wave (101) of an ear of a user and a photoplethysmographic pulse wave (102) of another portion of the user; transmitting, in a real-time and synchronized manner, to a processor the photoplethysmographic pulse wave (101) of the ear of the user and the photoplethysmographic pulse wave (102) of the other portion of the user; and processing, by means of theprocessor, the photoplethysmographic pulse wave (101) of the ear of the user and the photoplethysmographic pulse wave (102) of the other portion of the user to obtain a blood pressure value of the user. The method and system of the present invention improve accuracy of monitoring a blood pressure value of a user, and simplifies wearing of a monitoring device.

Description

[0001] The present application belongs to the technical field of wearable devices, and in particular relates to a blood pressure measurement method, a smart heart rate earphone and a system. Background technique [0002] Blood pressure is an important parameter that reflects the function of the user's circulatory system. In order to avoid the noise and discomfort caused by the existing electronic blood pressure monitor through the cuff to pressurize the arm, and to achieve continuous blood pressure measurement, pulse wave transit time (PWTT) is often used The user's blood pressure value can be obtained. [0003] Usually, photoplethysmography (PPG) is used to monitor electrocardiogram (ECG) and peripheral blood vessel (such as radial artery) pulse waves or pulse waves of any two parts of the body (such as carotid artery and radial artery) at the same time, and calculate the time between them Latency, that is, the time required for arterial blood to be ejected from the heart and...
