Description

一种血压测量方法、智能心率耳机及***Blood pressure measuring method, intelligent heart rate earphone and system

本申请属于可穿戴设备技术领域，尤其涉及一种血压测量方法、智能心率耳机及***。The present application belongs to the technical field of wearable devices, and in particular, to a blood pressure measuring method, an intelligent heart rate earphone, and a system.

背景技术Background technique

血压是反映用户循环***机能的重要参数，为了避免现有电子血压计通过袖带给手臂加压带来的噪声和不舒适感，以及实现连续的血压测量，多采用脉搏波传输时间(PWTT)可获得用户的血压数值。Blood pressure is an important parameter reflecting the function of the user's circulatory system. In order to avoid the noise and discomfort caused by the pressure of the existing electronic sphygmomanometer through the cuff, and to achieve continuous blood pressure measurement, the pulse wave transmission time (PWTT) is often used. The user's blood pressure value can be obtained.

通常采用光电容积脉搏波(PPG)同时监测心电(ECG)和外周血管(如桡动脉)脉搏波或者身体任意两个部位(如颈动脉和桡动脉)的脉搏波，计算它们之间的时间延迟，即动脉血从心脏喷出到传输至外周血管所需要的时间，从而获得脉搏波传输时间。通过脉搏波传输时间和动脉血压之间的模型，计算用户的血压数值。Photoelectric volume pulse wave (PPG) is usually used to monitor the pulse wave of ECG and peripheral blood vessels (such as radial artery) or pulse waves of any two parts of the body (such as carotid artery and radial artery), and calculate the time between them. The delay, that is, the time required for arterial blood to be ejected from the heart to the peripheral blood vessel, thereby obtaining the pulse wave transmission time. The blood pressure value of the user is calculated by a model between the pulse wave transmission time and the arterial blood pressure.

目前通过脉搏波传输时间来监测用户血压数值的手环手表等健康产品，其准确度很大程度上受到所采集的光电容积脉搏波的信噪比的影响。现在常采用手腕和相对应手指端进行光电容积脉搏波采集，而手腕处所采集的光电容积脉搏波的信噪比较差，影响了用户血压数值监测的准确度。同时由于需要同时监测手腕和手指端的光电容积脉搏波，常用的监测心电(ECG)方式和指环以及手环附加指环的方式，穿戴起来非常不便。At present, health products such as wristband watches that monitor the blood pressure of the user through the pulse wave transmission time are largely affected by the signal-to-noise ratio of the collected photoplethysmographic pulse wave. At present, the photoelectric volume pulse wave is often collected by the wrist and the corresponding finger end, and the signal-to-noise of the photoplethysmographic pulse wave collected at the wrist is relatively poor, which affects the accuracy of the blood pressure value monitoring of the user. At the same time, because it is necessary to simultaneously monitor the photoplethysmographic pulse wave of the wrist and the finger end, the commonly used method of monitoring the electrocardiogram (ECG) and the ring and the ring of the wristband are very inconvenient to wear.

具体地，参见图7，本申请通过将智能心率耳机1对准前肢相应的血管111，将其压在对应的骨骼110上。由所述智能心率耳机1中的心率芯片感知血管中血容量的变化，而压力传感器感受由手指通过智能心率耳机1施加的对血管111施加的压力值。其中当相应的手指通过智能心率耳机1施加的对血管111的压力值小于血管111的本身的压力值时，血液能正常通过相应的血管111，其光电容积脉搏波如图8的112所示。Specifically, referring to FIG. 7, the present application presses the smart heart rate earphone 1 against the corresponding blood vessel 111 of the forelimb by pressing it on the corresponding bone 110. The heart rate chip in the smart heart rate earphone 1 senses a change in blood volume in the blood vessel, and the pressure sensor senses a pressure value applied to the blood vessel 111 by the finger through the smart heart rate earphone 1. When the pressure value of the corresponding finger applied to the blood vessel 111 by the smart heart rate earphone 1 is smaller than the pressure value of the blood vessel 111 itself, the blood can normally pass through the corresponding blood vessel 111, and its photoplethysmographic pulse wave is as shown by 112 in FIG.

参见图9，当手指通过智能心率耳机1施加的对血管111的压力值继续增大时，相应的血管111会越来越窄，一直到施加的压力值与血管111本身的压力值相等时，整个血管111即完全闭合。由于此时血管111已经没有了血流，因此由所述心率芯片所监测到的光电容积脉搏波振幅低于阈值，即几乎变为一条直线，如图10的113所示。所述阈值为本领域技术人员根据人体特征进行设定。因此，此时由所述压力传感器所感知到的压力值即为所监测到的血管111的动脉压力值。Referring to FIG. 9, when the pressure value of the blood vessel 111 applied by the finger through the smart heart rate earphone 1 continues to increase, the corresponding blood vessel 111 becomes narrower and narrower until the applied pressure value is equal to the pressure value of the blood vessel 111 itself. The entire blood vessel 111 is completely closed. Since the blood vessel 111 has no blood flow at this time, the amplitude of the photoplethysmographic pulse wave detected by the heart rate chip is lower than the threshold value, that is, almost becomes a straight line, as shown by 113 in FIG. The threshold is set by a person skilled in the art according to human characteristics. Therefore, the pressure value sensed by the pressure sensor at this time is the monitored arterial pressure value of the blood vessel 111.

当所述心率芯片感测血管111的光电容积脉搏波振幅低于阈值时，本申请压力传感器感测用户通过所述智能心率耳机1对血管施加的压力值，所述压力传感器将至少两次感测的所述压力值发送至处理器以完成动脉血压值的定标。When the photoelectric volume pulse wave amplitude of the heart rate chip sensing blood vessel 111 is lower than a threshold, the pressure sensor of the present application senses a pressure value applied by the user through the smart heart rate earphone 1 to the blood vessel, and the pressure sensor will feel at least twice The measured pressure value is sent to the processor to complete the calibration of the arterial blood pressure value.

具体地，本申请利用位于所述智能便携终端2或者所述智能心率耳机1中的处理器将所述至少两次感测的所述压力值代入计算模型，通过解方程组获得参数a和b或者A和B的值，从而完成动脉血压值的定标。Specifically, the present application uses the processor located in the smart portable terminal 2 or the smart heart rate earphone 1 to substitute the at least two sensed pressure values into a calculation model by solving a system of equations. The values of parameters a and b or A and B are obtained, thereby completing the calibration of the arterial blood pressure value.
