技术领域Technical field

本申请涉及电子设备技术领域，具体涉及一种血压测量装置及方法。This application relates to the technical field of electronic equipment, in particular to a blood pressure measurement device and method.

背景技术Background technique

人体血压是指血管中脉动的血流对血管壁产生的侧向垂直于血管壁的压力，其中，压力的峰值为收缩压，也可称为高压，压力的谷值为舒张压，也可称为低压。血压是健康监测的一项重要指标，能够反映人体的健康状况，因此，如何方便地测量血压已成为热门的问题。Human blood pressure refers to the lateral pressure perpendicular to the blood vessel wall caused by the pulsating blood flow in the blood vessel. The peak of the pressure is the systolic pressure, which can also be called high pressure, and the valley of the pressure is the diastolic pressure, which can also be called For low pressure. Blood pressure is an important indicator of health monitoring and can reflect the health of the human body. Therefore, how to conveniently measure blood pressure has become a hot issue.

目前，常用手腕式血压仪测量血压，手腕式血压仪包括气囊、气泵和压力传感器，基于示波法原理：气泵向气囊充气，导致气囊加压膨胀，压迫腕部的桡动脉。集成在仪器内的压力传感器与气囊相连通，在充气升压过程中由于桡动脉受到压迫，压力传感器会提取脉搏振荡波信号，根据提取到的脉搏波振荡信号的特征来计算血压。但是手腕式血压仪结构复杂，设备体积较大，不易携带，测量舒适度体验较差，难以满足长时间连续测量的需求。At present, wrist blood pressure meters are commonly used to measure blood pressure. Wrist blood pressure meters include airbags, air pumps, and pressure sensors. Based on the principle of oscillometric method: the air pump inflates the airbags, causing the airbags to inflate and compress the radial artery of the wrist. The pressure sensor integrated in the instrument is connected to the airbag. During the inflation and boosting process, the radial artery is compressed, the pressure sensor will extract the pulse oscillation wave signal, and calculate the blood pressure based on the characteristics of the extracted pulse wave oscillation signal. However, the wrist-type blood pressure meter has a complex structure, a large device size, is not easy to carry, and has a poor measurement comfort experience, which is difficult to meet the needs of long-term continuous measurement.

另一种手表式血压计，通过人工确定桡动脉的位置，适用机械泵的方式进行加压。血压测量一般基于张力法原理：对体表动脉部分施加外压，使血管内周应力(张力)发生变化；当外力达到某一特定值时，血管呈扁平状态，血管内压力与外力相等，此时压力传感器测得的压力与动脉血压呈比例；因此可通过压力传感器输出获取动脉压力波，进而根据压力波估计血压值。但是在测量过程中难以保证压力传感器精确定位在被测动脉被压扁部位的正上方，并且在连续测量过程中，大范围长时间的手腕压迫容易使得用户产生不适。Another type of watch-type sphygmomanometer uses a mechanical pump to pressurize the radial artery by manually determining the position. Blood pressure measurement is generally based on the principle of tension method: applying external pressure to the surface arteries, causing changes in the inner peripheral stress (tension) of the blood vessels; when the external force reaches a certain value, the blood vessels are in a flat state, and the intravascular pressure is equal to the external force. The pressure measured by the pressure sensor is proportional to the arterial blood pressure; therefore, the arterial pressure wave can be obtained through the output of the pressure sensor, and then the blood pressure value can be estimated based on the pressure wave. However, during the measurement process, it is difficult to ensure that the pressure sensor is accurately positioned directly above the compressed part of the measured artery, and in the continuous measurement process, a wide range of long-time wrist compression is likely to cause discomfort to the user.

为了便于理解，示例的给出了部分与本申请实施例相关概念的说明以供参考。如下所示：For ease of understanding, some illustrations of concepts related to the embodiments of the present application are given as examples for reference. As follows:

本申请实施例中的血压测量装置可以应用在可穿戴医疗设备领域、日常监护等，如图1所示为现有的腕带式血压计100，采用的是示波法测量血压。具体地，首先把腕带102捆在手腕上，对腕带充气，到一定压力后停止加压，血流在血管中流通时，会有一定的振荡波，振荡波通过气管传播到压力传感器，压力传感能实时检测到所测腕带内的压力及波动，处理器会将压力传感器检测到的压力信号分离为两部分：线性加压基线信号和脉搏振荡波信号，线性加压基线信号是从压力信号中分离出的随时间呈线性变化的部分信号，之后通过测得的脉搏振荡波信号与线性加压基线信号来计算血压值，其中当脉搏振荡波的振幅最大时，对应的是平均血压(mean blood pressure，MBP)，收缩压(systolic blood pressure，SBP)对应于脉搏振荡波信号包络线的第一个拐点，舒张压(diastolic blood pressure，DBP)对应于脉搏振荡波信号包络线的第二个拐点。The blood pressure measurement device in the embodiment of the present application can be applied in the field of wearable medical equipment, daily monitoring, etc. As shown in FIG. 1, the existing wristband type blood pressure monitor 100 uses the oscillometric method to measure blood pressure. Specifically, first tie the wristband 102 to the wrist, inflate the wristband, and stop the compression after reaching a certain pressure. When the blood flow circulates in the blood vessel, there will be a certain oscillating wave, which propagates through the trachea to the pressure sensor. The pressure sensor can detect the pressure and fluctuations in the measured wristband in real time. The processor separates the pressure signal detected by the pressure sensor into two parts: the linear compression baseline signal and the pulse oscillation wave signal. The linear compression baseline signal is The part of the signal that changes linearly with time is separated from the pressure signal, and then the blood pressure value is calculated by the measured pulse oscillation wave signal and the linear pressurization baseline signal. When the amplitude of the pulse oscillation wave is the largest, the corresponding is the average Blood pressure (mean blood pressure, MBP), systolic blood pressure (systolic blood pressure, SBP) correspond to the first inflection point of the pulse oscillation wave signal envelope, and diastolic blood pressure (DBP) correspond to the pulse oscillation wave signal envelope The second inflection point of the line.

当用户利用腕带式血压计进行连续循环测量时，多次充气加压压迫血管会使得佩戴该测量装置的用户感觉到明显的不适，特别是夜晚休息时连续测量，会对用户的睡眠造成影响。When the user uses a wristband sphygmomanometer to perform continuous cycle measurement, multiple inflation and compression to compress the blood vessel will cause the user wearing the measurement device to feel obvious discomfort, especially when the continuous measurement is at rest at night, it will affect the user’s sleep .

如图2所示为现有的手表式血压计，采用的是张力测定法测量血压，张力测定法的原理是使用气囊或其他装置压迫血管到扁平状态，动脉搏动对覆盖在动脉表面的压力传感器产生冲击，使得传感器产生形变，产生压力脉搏振荡波信号。当血管压迫到扁平状态时，血管近似刚性设备，动脉血管外测量得到的脉搏振荡波信号的幅度和动脉血压成线性关系。测量得到的压力脉搏波峰和波谷幅度值需要定标，即在测量到压力脉搏波的同时或者很短时间内，使用其他测量血压的标准方法测量真实的动脉收缩压和舒张压，将压力脉搏波的波峰和波谷幅度值分别线性映射到真实的动脉收缩压和舒张压。再次测量血压的时候只需要通过张力测定法测量得到压力脉搏振荡波信号，就可以根据事先确定的定标关系计算出收缩压和舒张压。因为张力测定法可以采集到beat-to-beat的压力脉搏波，所以张力测定法可以被用来连续测量血压。但是，在该方法下，在采集过程中需要保证压力传感器精确定位在被测动脉被压扁部位的正上方，需要持续的加压来判定多大的压力可以使得动脉血管压迫至扁平状态，当压力传感器与动脉血管之间产生相对运动，测量出来的血压可靠性低。Figure 2 shows the existing watch-type sphygmomanometer, which uses the tension measurement method to measure blood pressure. The principle of the tension measurement method is to use a balloon or other device to compress the blood vessel to a flat state. The impact is generated, the sensor is deformed, and the pressure pulse oscillation wave signal is generated. When the blood vessel is compressed to a flat state, the blood vessel is similar to a rigid device, and the amplitude of the pulse oscillation wave signal measured outside the artery has a linear relationship with the arterial blood pressure. The measured pressure pulse peak and trough amplitude values need to be calibrated, that is, when the pressure pulse wave is measured or within a short period of time, use other standard methods for measuring blood pressure to measure the true arterial systolic and diastolic blood pressure, and the pressure pulse wave The peak and trough amplitude values are linearly mapped to the true arterial systolic and diastolic blood pressure, respectively. When the blood pressure is measured again, only the pressure pulse oscillation wave signal needs to be measured by the tension measurement method, and the systolic and diastolic blood pressure can be calculated according to the pre-determined calibration relationship. Because tonometry can collect beat-to-beat pressure pulse waves, tonometry can be used to continuously measure blood pressure. However, in this method, it is necessary to ensure that the pressure sensor is accurately positioned directly above the compressed part of the measured artery during the acquisition process, and continuous pressure is required to determine how much pressure can make the artery and blood vessel compress to a flat state. Relative movement occurs between the sensor and arterial blood vessels, and the reliability of the measured blood pressure is low.

本申请实施例提供一种血压测量方法及装置，用以解决当血压测量装置采用波形分析法连续测量血压时，多次充气加压压迫血管影响用户正常生活，舒适度差；而采用张力测定法连续测量血压时，难以快速获知持续加压所需的压力，使得连续监测过程中连续充气让用户产生不适的问题。本申请提供的方法和装置可以在不影响正常工作生活的前提下保障测量的准确度。该血压测量装置在医疗市场也具有潜在的应用场景，可以作为连续血压测量使用，提高用户的舒适度。The embodiments of the present application provide a blood pressure measurement method and device to solve the problem that when the blood pressure measurement device uses the waveform analysis method to continuously measure blood pressure, multiple inflation and compression compress the blood vessel, which affects the normal life of the user, and the comfort is poor; and the tension measurement method is adopted. When continuously measuring blood pressure, it is difficult to quickly know the pressure required for continuous compression, which makes continuous inflation in the continuous monitoring process causing discomfort to the user. The method and device provided in this application can ensure the accuracy of measurement without affecting normal work and life. The blood pressure measurement device also has potential application scenarios in the medical market, and can be used as a continuous blood pressure measurement to improve user comfort.

The product form of the blood pressure measurement device in the embodiment of the present application can be specifically as shown in Figure 3. The width of the wristband 12 is narrower than that of the existing wristband type blood pressure monitor, which is similar to the width of the wristband of an ordinary watch, and is more convenient for users. Wear.

如图4所示，血压测量装置可以包括与腕带12相连的第一气囊121及第二气囊122。其中，第一气囊121的长度小于所述腕带12的周长，所述第一气囊121用于对所述身体部位进行局部施压；当微泵113充气空气至第一气囊121时，第一气囊121能够紧压在用户身体部位的动脉血管区域，将动脉血管压迫至扁平状态，此时手腕部的其他部位不受第一气囊121的压迫。As shown in FIG. 4, the blood pressure measurement device may include a first airbag 121 and a second airbag 122 connected to the wristband 12. Wherein, the length of the first airbag 121 is less than the circumference of the wristband 12, and the first airbag 121 is used to locally apply pressure to the body part; when the micropump 113 inflates air to the first airbag 121, the first airbag 121 An airbag 121 can compress the arterial blood vessel area of the user's body and compress the arterial blood vessel to a flat state. At this time, other parts of the wrist are not compressed by the first airbag 121.

When the micro-pump inflates air to the second airbag 122, the second airbag 122 can be compressed around the user's wrist.

图5a为本申请实施例提供的血压测量装置的一种腕带的结构示意图，如图5a所示，腕带12上设有第一气囊121，所述第一气囊121用于对所述身体部位进行局部施压，柔性阵列传感器13设置于第一气囊121远离腕带的表面。Figure 5a is a schematic structural diagram of a wristband of a blood pressure measurement device provided by an embodiment of the application. As shown in Figure 5a, the wristband 12 is provided with a first airbag 121, which is used to protect the body Local pressure is applied to the location, and the flexible array sensor 13 is arranged on the surface of the first airbag 121 away from the wristband.

图5b为本申请实施例提供的血压测量装置的一种腕带的剖面示意图。如图5b所示，柔性阵列传感器13、第一气囊121、第二气囊122及腕带12可以依次叠设于用户皮肤表面。其中，第一气囊121与第二气囊122位置可以互换。Fig. 5b is a schematic cross-sectional view of a wristband of a blood pressure measurement device provided by an embodiment of the application. As shown in FIG. 5b, the flexible array sensor 13, the first airbag 121, the second airbag 122, and the wristband 12 may be sequentially stacked on the surface of the user's skin. Wherein, the positions of the first airbag 121 and the second airbag 122 can be interchanged.

下面结合血压测量装置各组成部分的功能描述本申请一种实施例中血压测量的流程：The following describes the blood pressure measurement process in an embodiment of the present application in conjunction with the functions of each component of the blood pressure measurement device:

首先，找到用户的桡动脉大概的位置范围，以手腕为例，将腕带缠绕并且贴合于用户的手腕部位，且确保柔性阵列传感器的感应区域覆盖在桡动脉区域的上方。First, find the approximate location range of the user's radial artery. Take the wrist as an example. Wrap and fit the wristband on the user's wrist, and ensure that the sensing area of the flexible array sensor covers the area of the radial artery.

其次，处理器111对微泵113进行控制以使得微泵113通过气泵接口115对第二气囊122进行充气，第一气囊121不充气，保证第二气囊122对手腕环绕式施加压力，优选地，采用线性施加压力的方式。可以理解的是，用户的整个手腕受腕带充气后被压迫。在一种实施方式中，可以通过对第二气囊122匀速充气来实现对手腕线性施加压力。Secondly, the processor 111 controls the micropump 113 so that the micropump 113 inflates the second airbag 122 through the air pump interface 115, and the first airbag 121 is not inflated to ensure that the second airbag 122 applies pressure around the wrist. Preferably, Adopt the method of applying pressure linearly. It is understandable that the entire wrist of the user is compressed after being inflated by the wristband. In an embodiment, the second airbag 122 may be inflated at a uniform speed to achieve linear pressure application to the wrist.

在加压的过程中，第二气囊122压迫用户手腕部位的血管，阻断血管内的血流，之后微泵113对第二气囊122慢速放气，血管内的血液重新流动。在此过程中血液造成的振动变化可以反映血管内的血压变化，因此采用压力传感器112检测第二气囊122内的压力波信号，压力传感器112的敏感元件连接着第二气囊122，该敏感元件可以获取到第二气囊122的压力波信号，之后敏感元件可以通过传感器接口114将压力波信号传输到压力传感器112，压力传感器112将压力波信号发送至处理器111。During the pressurization process, the second balloon 122 compresses the blood vessel in the user's wrist, blocking the blood flow in the blood vessel, and then the micropump 113 slowly deflates the second balloon 122, and the blood in the blood vessel re-flows. In this process, the vibration change caused by blood can reflect the blood pressure change in the blood vessel. Therefore, the pressure sensor 112 is used to detect the pressure wave signal in the second air bag 122. The sensitive element of the pressure sensor 112 is connected to the second air bag 122. After obtaining the pressure wave signal of the second airbag 122, the sensitive element can transmit the pressure wave signal to the pressure sensor 112 through the sensor interface 114, and the pressure sensor 112 sends the pressure wave signal to the processor 111.

处理器111获取所述压力传感器采集的压力波信号a，并采用示波法测量用户的血压值，根据所述血压值确定第一气囊121所需要局部施加的压力范围。The processor 111 obtains the pressure wave signal a collected by the pressure sensor, measures the user's blood pressure value by using the oscillometric method, and determines the pressure range that the first airbag 121 needs to locally apply according to the blood pressure value.

如图6所示，处理器111压力波信号a中分离得到脉搏振荡波信号b，并对所述脉搏振荡波信号进行波峰拟合，得到振荡波包络c；通过分析所述振荡波包络与血压之间的函数关系得到所述用户的血压值，所述血压值包括收缩压及舒张压。通过定位振荡波包络左边的导数极值点rs和右边的导数极值点rd的位置，将rs和rd在压力波基线上对应的压强分别作为收缩压测量值和舒张压测量值。然后，利用血压值(收缩压测量值和舒张压测量值)计算出合适的局部加压范围。As shown in FIG. 6, the processor 111 separates the pressure wave signal a to obtain the pulse oscillation wave signal b, and performs peak fitting on the pulse oscillation wave signal to obtain the oscillation wave envelope c; The functional relationship between the blood pressure and the blood pressure obtains the blood pressure value of the user, and the blood pressure value includes the systolic blood pressure and the diastolic blood pressure. By locating the position of the derivative extreme point rs on the left side of the oscillation wave envelope and the derivative extreme point rd on the right side, the pressure corresponding to rs and rd on the pressure wave baseline is used as the measured value of systolic blood pressure and the measured value of diastolic blood pressure, respectively. Then, using blood pressure values (measured systolic blood pressure and measured diastolic blood pressure) to calculate the appropriate local compression range.

在其他实施方式中，也可以利用示波法改进方法来计算出血压值，例如变幅度系数法、拐点法和幅度系数法相结合判定血压、系数差分比值法等等，在此不做限定。通过示波法测量血压目的在于测量得到用户较为真实准确的收缩压及舒张压，从而能够根据测量得到的收缩压及舒张压确定局部加压范围。In other embodiments, an improved method of the oscillometric method can also be used to calculate the blood pressure value, such as variable amplitude coefficient method, inflection point method and amplitude coefficient method combined to determine blood pressure, coefficient difference ratio method, etc., which are not limited here. The purpose of measuring blood pressure by the oscillometric method is to measure the user's true and accurate systolic and diastolic blood pressure, so that the local compression range can be determined based on the measured systolic and diastolic blood pressure.

示例性地，当用户的收缩压测量值为120mmHg和舒张压测量值为80mmHg。通过血压换算关系，得到加压范围为50～130mmHg，即6659～17313pa。Exemplarily, when the user's systolic blood pressure measurement value is 120 mmHg and the diastolic blood pressure measurement value is 80 mmHg. Through the blood pressure conversion relationship, the pressure range is 50～130mmHg, that is, 6659～17313pa.

需要说明的是，可以利用本实施例提供的血压测量装置先采用示波法测量得到用户较为准确的单次血压值，然后再利用张力法进行连续血压测量；还可以利用其他的测量装置(例如水银血压计)来获取用户较为准确的血压值，将血压值输入本实施例提供的血压测量装置，然后再利用本实施例提供的血压测量装置采用张力法进行连续血压测量。It should be noted that the blood pressure measurement device provided in this embodiment can be used to first use the oscillometric method to measure the user's more accurate single blood pressure value, and then use the tension method to perform continuous blood pressure measurement; other measurement devices (such as Mercury sphygmomanometer) to obtain the user's more accurate blood pressure value, input the blood pressure value into the blood pressure measurement device provided in this embodiment, and then use the blood pressure measurement device provided in this embodiment to perform continuous blood pressure measurement using the tension method.

然后，处理器111通过驱动电路对微泵113进行控制以使得微泵通过气泵接口115对第一气囊121充气至第一气囊121内的压力达到计算得到的压力范围，以对用户的身体部位进行局部施压。这时，第二气囊122不充气，第一气囊121压迫用户手腕部位的桡动脉血管至扁平状态，动脉搏动对覆盖在桡动脉表面的柔性阵列传感器产生冲击，使得柔性阵列传感器产生形变，产生脉搏振荡波信号。可以理解地，动脉血管外测量得到的脉搏振荡波信号的幅度和动脉血压成线性关系。Then, the processor 111 controls the micropump 113 through the driving circuit so that the micropump inflates the first airbag 121 into the first airbag 121 through the air pump interface 115 to reach the calculated pressure range, so as to perform treatment on the body parts of the user. Local pressure. At this time, the second airbag 122 is not inflated, and the first airbag 121 compresses the radial artery blood vessel in the user's wrist to a flat state, and the arterial pulse impacts the flexible array sensor covering the surface of the radial artery, causing the flexible array sensor to deform and generate pulse. Oscillating wave signal. Understandably, the amplitude of the pulse oscillation wave signal measured outside the arterial blood vessel has a linear relationship with the arterial blood pressure.

在局部施加压力过程中，处理器111获取所述柔性阵列传感器中首个采集到的脉搏振荡波信号的第一传感器及采集到脉搏振荡波最大幅值的第二传感器；当所述第一传感器与所述第二传感器不是同一传感器时，将所述第一传感器及所述第二传感器采集的脉搏振荡波信号进行融合，并根据融合后的脉搏振荡波信号计算所述用户的血压值。In the process of applying pressure locally, the processor 111 acquires the first sensor that collects the first pulse oscillation wave signal and the second sensor that collects the maximum amplitude of the pulse oscillation wave among the flexible array sensors; when the first sensor When the second sensor is not the same sensor, the pulse oscillation wave signals collected by the first sensor and the second sensor are fused, and the blood pressure value of the user is calculated according to the fused pulse oscillation wave signal.

可以理解地，在局部施加压力过程中，处理器111采用张力法进行血压测量。具体地，处理器111获取所述压力传感器采集的压力波信号，从所述压力波信号中分离得到线性加压基线信号，根据所述融合后的脉搏振荡波信号及所述线性加压基线信号计算得到血压值。例如，可以通过提取脉搏振荡波峰值序列拟合振荡波包络线，查找包络线峰值点，确定包络线峰值左右的两个拐点，随后分别得到两个拐点在脉搏震荡波信号包络线中对应的第一时间点和第二时间点，进而根据确定的第一时间点和第二时间点在线性加压基线信号中对应的压强分别作为收缩压测量值和舒张压测量值。Understandably, in the process of locally applying pressure, the processor 111 uses a tension method to measure blood pressure. Specifically, the processor 111 obtains the pressure wave signal collected by the pressure sensor, separates the linear pressurization baseline signal from the pressure wave signal, and obtains a linear pressurization baseline signal according to the fused pulse oscillation wave signal and the linear pressurization baseline signal Calculate the blood pressure value. For example, you can fit the envelope of the pulse oscillation wave by extracting the peak sequence of the pulse oscillation wave, find the peak point of the envelope, determine the two inflection points around the peak of the envelope, and then obtain the two inflection points at the pulse oscillation wave signal envelope. The first time point and the second time point corresponding to the corresponding first time point and the second time point, and the corresponding pressure in the linear compression baseline signal according to the determined first time point and second time point are respectively used as the systolic blood pressure measurement value and the diastolic blood pressure measurement value.

压力波信号可以表示血管内的血压变化，可以包括基线分量和动态信号分量，处理器111可以对压力波信号进行带通滤波，得到脉搏振荡波信号，即为压力波信号中的动态信号分量，从压力波信号中去除脉搏振荡波信号后即可得到线性加压基线信号，即为压力波信号中的基线分量。其中，带通滤波器的通带可以设置为0.5-10Hz(赫兹)。而舒张压时间点在压力波信号的基线分量中对应的测量值即为舒张压测量值，收缩压时间点在压力波信号的基线分量中对应的测量值即为收缩压测量值。The pressure wave signal can represent the blood pressure change in the blood vessel, and can include a baseline component and a dynamic signal component. The processor 111 can band-pass filter the pressure wave signal to obtain the pulse oscillation wave signal, which is the dynamic signal component in the pressure wave signal. After removing the pulse oscillation wave signal from the pressure wave signal, a linear pressurized baseline signal can be obtained, which is the baseline component in the pressure wave signal. Among them, the pass band of the band pass filter can be set to 0.5-10 Hz (Hertz). The measured value corresponding to the baseline component of the pressure wave signal at the time point of diastolic blood pressure is the measured value of diastolic blood pressure, and the measurement value corresponding to the baseline component of the pressure wave signal at the time point of systolic pressure is the measured value of systolic blood pressure.

若第一传感器与第二传感器为已同一个传感器，则根据该传感器采集的脉搏振荡波信号及压力波信号确定用户的血压值。If the first sensor and the second sensor are the same sensor, the blood pressure value of the user is determined according to the pulse oscillation wave signal and the pressure wave signal collected by the sensor.

对第二气囊进行充气增压，以对所述用户的身体部位进行环绕式施压，其中，所述第二气囊与所述压力传感器相连；在环绕式施压过程中，获取所述压力传感器采集的所述第二气囊内的压力波信号；从所述压力波信号中分离得到脉搏振荡波信号，并对所述脉搏振荡波信号进行波峰拟合，得到振荡波包络；通过分析所述振荡波包络与血压之间的函数关系得到所述用户的血压值；根据所述血压值确定所述第一气囊所需要施加的压力范围。The second airbag is inflated and pressurized to apply pressure to the body part of the user in a surrounding manner, wherein the second airbag is connected to the pressure sensor; during the surrounding pressure application process, the pressure sensor is acquired The pressure wave signal in the second balloon is collected; the pulse oscillation wave signal is separated from the pressure wave signal, and the peak of the pulse oscillation wave signal is fitted to obtain the oscillation wave envelope; by analyzing the The functional relationship between the oscillating wave envelope and the blood pressure obtains the blood pressure value of the user; and the pressure range that the first airbag needs to be applied is determined according to the blood pressure value.

具体地，处理器111对微泵113进行控制以使得微泵113通过气泵接口115对第二气囊122进行充气，所述第二气囊122用于对所述身体部位进行环绕式施压，优选地，采用线性施加压力的方式。可以理解的是，用户的整个手腕受腕带充气后被压迫。在一种实施方式中，可以通过对气囊12匀速充气来实现对手腕线性施加压力。Specifically, the processor 111 controls the micropump 113 so that the micropump 113 inflates the second airbag 122 through the air pump interface 115, and the second airbag 122 is used to pressurize the body part in a circumferential manner, preferably , Adopt the method of applying pressure linearly. It is understandable that the entire wrist of the user is compressed after being inflated by the wristband. In an embodiment, the airbag 12 can be inflated at a uniform speed to achieve linear pressure on the wrist.

在加压的过程中，第二气囊122压迫用户手腕部位的血管，阻断血管内的血流，之后微泵113对第二气囊122慢速放气，血管内的血液重新流动。在此过程中血液造成的振动变化可以反映血管内的血压变化，因此采用压力传感器112检测气囊内的压力波信号，压力传感器112的敏感元件连接着气囊，该敏感元件可以获取到气囊内的压力波信号，之后敏感元件可以通过传感器接口114将压力波信号传输到压力传感器112，压力传感器112将压力波信号发送至处理器111。During the pressurization process, the second balloon 122 compresses the blood vessel in the user's wrist, blocking the blood flow in the blood vessel, and then the micropump 113 slowly deflates the second balloon 122, and the blood in the blood vessel re-flows. In this process, the vibration change caused by blood can reflect the blood pressure change in the blood vessel. Therefore, the pressure sensor 112 is used to detect the pressure wave signal in the air bag. The sensitive element of the pressure sensor 112 is connected to the air bag, and the sensitive element can obtain the pressure in the air bag After that, the sensitive element can transmit the pressure wave signal to the pressure sensor 112 through the sensor interface 114, and the pressure sensor 112 sends the pressure wave signal to the processor 111.

如图6所示，处理器111压力波信号a中分离得到脉搏振荡波信号b，并对所述脉搏振荡波信号进行波峰拟合，得到振荡波包络c；通过分析所述振荡波包络与血压之间的函数关系得到所述用户的血压值，所述血压值包括收缩压及舒张压。通过定位振荡波包络左边的导数极值点rs和右边的导数极值点rd的位置，将rs和rd在压力波基线上对应的压强分别作为收缩压测量值和舒张压测量值。然后，利用血压值(收缩压测量值和舒张压测量值)计算出合适的局部加压范围。As shown in FIG. 6, the processor 111 separates the pressure wave signal a to obtain the pulse oscillation wave signal b, and performs peak fitting on the pulse oscillation wave signal to obtain the oscillation wave envelope c; The functional relationship between the blood pressure and the blood pressure obtains the blood pressure value of the user, and the blood pressure value includes the systolic blood pressure and the diastolic blood pressure. By locating the position of the derivative extreme point rs on the left side of the oscillation wave envelope and the derivative extreme point rd on the right side, the pressure corresponding to rs and rd on the pressure wave baseline is used as the measured value of systolic blood pressure and the measured value of diastolic blood pressure, respectively. Then, the blood pressure values (measured systolic blood pressure and measured diastolic blood pressure) are used to calculate the appropriate local compression range.

在其他实施方式中，也可以利用示波法改进方法来计算出血压值，例如变幅度系数法、拐点法和幅度系数法相结合判定血压、系数差分比值法等等，在此不做限定。通过示波法测量血压目的在于测量得到用户较为真实准确的收缩压及舒张压，从而能够根据测量得到的收缩压及舒张压确定局部加压范围。In other embodiments, an improved method of the oscillometric method can also be used to calculate the blood pressure value, for example, the variable amplitude coefficient method, the inflection point method and the amplitude coefficient method are combined to determine the blood pressure, the coefficient difference ratio method, etc., which are not limited herein. The purpose of measuring blood pressure by the oscillometric method is to measure the user's true and accurate systolic and diastolic blood pressure, so that the local compression range can be determined based on the measured systolic and diastolic blood pressure.

在一种实施方式中，所述获取血压测量装置的第一气囊所需要施加的压力范围，包括：获取输入的所述待监测用户的血压值；根据预设的血压换算关系计算得到所述第一气囊所需要局部施加的压力范围。In one embodiment, the obtaining the pressure range required by the first airbag of the blood pressure measurement device includes: obtaining the input blood pressure value of the user to be monitored; calculating the first blood pressure according to a preset blood pressure conversion relationship. The range of pressure that an airbag needs to apply locally.

需要说明的是，可以利用本实施例提供的血压测量装置先采用示波法测量得到用户较为准确的单次血压值，然后再利用张力法进行连续血压测量；还可以将血压值输入本实施例提供的血压测量装置，然后再利用本实施例提供的血压测量装置采用张力法进行连续血压测量，其中，输入的血压值可以是利用其他的测量装置(例如水银血压计)获得的用户的较为准确的血压值。It should be noted that the blood pressure measurement device provided in this embodiment can be used to first use the oscillometric method to measure the user's more accurate single blood pressure value, and then use the tension method to perform continuous blood pressure measurement; the blood pressure value can also be input into this embodiment The blood pressure measurement device provided in the present embodiment is then used to perform continuous blood pressure measurement using the tension method. The blood pressure value input can be the user's more accurate information obtained by other measurement devices (such as mercury sphygmomanometers). Blood pressure value.

步骤S02，对第一气囊进行充气增压，使得第一气囊内的压力调节至所述压力范围，以对用户的身体部位进行局部施压。In step S02, the first airbag is inflated and pressurized, so that the pressure in the first airbag is adjusted to the pressure range, so as to locally apply pressure to the user's body part.

具体地，处理器控制所述微泵对与所述柔性阵列传感器位置相对应的第一气囊121进行充气，以实现对动脉血管局部施加压力至确定的压力范围，这时，第一气囊121压迫用户手腕部位的桡动脉血管至扁平状态，动脉搏动对覆盖在桡动脉表面的柔性阵列传感器产生冲击，使得柔性阵列传感器产生形变，产生压力脉搏振荡波信号。可以理解地，第二气囊122不充气，第一气囊121压迫在动脉血管区域，而不是压迫用户的整个腕部，降低不适感。需要说明的是，动脉血管外测量得到的脉搏振荡波信号的幅度和动脉血压成线性关系。Specifically, the processor controls the micropump to inflate the first balloon 121 corresponding to the position of the flexible array sensor, so as to apply pressure locally to the arterial blood vessel to a certain pressure range. At this time, the first balloon 121 compresses The radial artery blood vessel in the user's wrist reaches a flat state, and the arterial pulse impacts the flexible array sensor covering the surface of the radial artery, causing the flexible array sensor to deform and generate a pressure pulse oscillation wave signal. Understandably, the second airbag 122 is not inflated, and the first airbag 121 compresses the arterial blood vessel area instead of compressing the entire wrist of the user, thereby reducing discomfort. It should be noted that the amplitude of the pulse oscillation wave signal measured outside the arterial blood vessel has a linear relationship with the arterial blood pressure.

可以理解地，柔性阵列传感器是由多个传感器以矩形阵列或环形阵列的方式排布于腕带上。其中，矩形阵列是指把对象按行、列方式进行分布；环形阵列是指把对象绕阵列中心等角度均匀分布。It is understandable that the flexible array sensor consists of a plurality of sensors arranged on the wristband in a rectangular array or a circular array. Among them, the rectangular array refers to the distribution of objects in rows and columns; the circular array refers to the uniform distribution of objects around the center of the array at an equal angle.

在本实施例中，柔性阵列传感器为矩形阵列排列的传感器模组，可以理解地，在心脏搏动周期内，外周血管中的微动脉、毛细血管和微静脉内流过的血液相应的呈脉动性变化。当心脏收缩时血液容积最大，而在心脏舒张时容积最小。血液容积这种脉动性变化一般可通过光电容积传感器获得，所得的波形中含有容积脉搏血流信息。因此可以通过容积脉搏血流信息和血压信号的关系来获得收缩压和舒张压，该法被称为光电容积脉搏波描记法(Photo Plethysmo Graphy，PPG)。In this embodiment, the flexible array sensor is a sensor module arranged in a rectangular array. It can be understood that the blood flowing in the arterioles, capillaries and venules in the peripheral blood vessels is correspondingly pulsatile during the heart beat cycle. Variety. The volume of blood is maximum when the heart is contracting, and the volume is minimum when the heart is diastolic. This pulsating change in blood volume can generally be obtained by a photoelectric volume sensor, and the resulting waveform contains volume pulse blood flow information. Therefore, the systolic and diastolic blood pressure can be obtained through the relationship between the volume pulse blood flow information and the blood pressure signal. This method is called photoplethysmograph (Photoplethysmo Graphy, PPG).

由于受到指端皮肤肌肉组织和血液的吸收衰减作用，光电接收器检测到的光强度将会减弱。其中皮肤、肌肉和组织等对光的吸收在整个血液循环中是保持恒定不变的，而皮肤内的血液容积在心脏收缩舒张作用下呈搏动性变化。当心脏收缩时外周血管血容量最多，光吸收量也最大，检测到的光强度最小；而在心脏舒张时，正好相反，外周血管血容量最少，检测到的光强度最大，使光电接收器检测到的光强度随之呈脉动性变化。再将此光强度变化信号转换成电信号，将此电信号经放大器后便可获得容积脉搏血流的变化。Due to the absorption and attenuation of the fingertip skin muscle tissue and blood, the light intensity detected by the photoelectric receiver will be weakened. The absorption of light by the skin, muscles and tissues remains constant throughout the blood circulation, while the blood volume in the skin shows a pulsating change under the action of cardiac contraction and relaxation. When the heart is contracting, the peripheral blood volume is the largest, the light absorption is also the largest, and the detected light intensity is the smallest; while in diastole, the opposite is true, the peripheral blood volume is the least, and the detected light intensity is the largest, so that the photoelectric receiver detects The intensity of the received light then showed a pulsating change. Then the light intensity change signal is converted into an electrical signal, and the volume pulse blood flow change can be obtained after the electrical signal is passed through the amplifier.

步骤S03，在局部施压过程中，获取所述柔性阵列传感器中首个采集到脉搏振荡波信号的第一传感器，获取采集到最大幅值的脉搏振荡波信号的第二传感器；其中，所述柔性阵列传感器与用户的动脉血管区域的皮肤表面接触。Step S03, in the process of local pressure, the first sensor that collects the pulse oscillation wave signal first among the flexible array sensors is acquired, and the second sensor that collects the pulse oscillation wave signal of the maximum amplitude is acquired; wherein, the The flexible array sensor is in contact with the skin surface of the user's arterial blood vessel area.

具体的，在采集过程中，记录首先采集到脉搏振荡波信号的传感器为第一传感器，记录采集到最大幅值的脉搏振荡波信号的传感器记为第二传感器。Specifically, in the collection process, the sensor that records the first collected pulse oscillation wave signal is the first sensor, and the sensor that records the pulse oscillation wave signal with the largest amplitude collected is the second sensor.

当测量装置在测量血压时，柔性阵列传感器位于用户手腕部位的桡动脉区域，并且以预设的压力范围压在用户的皮肤表面。预设的压力范围能够压迫用户手腕部位的桡动脉血管至扁平状态，动脉搏动对覆盖在桡动脉表面的柔性阵列传感器产生冲击，使得柔性阵列传感器产生形变，产生压力脉搏振荡波信号。When the measuring device is measuring blood pressure, the flexible array sensor is located in the radial artery area of the user's wrist and is pressed against the user's skin surface with a preset pressure range. The preset pressure range can compress the radial artery blood vessel in the user's wrist to a flat state, and the arterial pulse impacts the flexible array sensor covering the surface of the radial artery, causing the flexible array sensor to deform and generate a pressure pulse oscillation wave signal.

步骤S04，当所述第一传感器与所述第二传感器不是同一传感器时，将所述第一传感器及所述第二传感器采集的脉搏振荡波信号进行融合。Step S04: When the first sensor and the second sensor are not the same sensor, the pulse oscillation wave signals collected by the first sensor and the second sensor are fused.

具体地，当所述第一传感器与所述第二传感器的标识码一致时，确认第一传感器与第二传感器为同一传感器。Specifically, when the identification codes of the first sensor and the second sensor are consistent, it is confirmed that the first sensor and the second sensor are the same sensor.

例如，第一传感器和第二传感器的标识码均为N _1,5，那么就是同一传感器，说明柔性阵列传感器中只有一个传感器正压在动脉上方，如图8a所示，此时传感器B号正压在桡动脉的正上方。 For example, if the identification codes of the first sensor and the second sensor are both N _1,5 , then it is the same sensor, indicating that only one sensor in the flexible array sensor is positively pressed above the artery, as shown in Figure 8a, at this time, the number of sensor B is positive. Press directly above the radial artery.

当所述第一传感器与所述第二传感器的标识码不一致时，例如第一传感器的标识码为N _1,5，第二传感器的标识码为N _2,5，那么第一传感器与第二传感器不是同一个传感器。如图8b所示，柔性阵列传感器中有两个相邻的传感器(传感器B及传感器C)并列共同压在了动脉上方，需要提取两路脉搏振荡波信号，进行融合的计算。 When the identification codes of the first sensor and the second sensor are inconsistent, for example, the identification code of the first sensor is N _1,5 and the identification code of the second sensor is N _2,5 , then the first sensor and the second sensor The sensors are not the same sensor. As shown in Figure 8b, two adjacent sensors (sensor B and sensor C) in the flexible array sensor are juxtaposed and pressed together above the artery, and two pulse oscillation wave signals need to be extracted for fusion calculation.

在一种实施方式中，将所述第一传感器与所述第二传感器采集的脉搏振荡波信号根据预设的权重比例进行融合，根据融合后的脉搏振荡波信号计算用户的血压值。例如第一传感器采集的脉搏振荡波信号为第一路信号(S1)，第二传感器采集的脉搏振荡波信号为第二路信号(S2)，并且，第一路信号的权重为m1，第二路信号的权重为m2，则融合后的脉搏振荡波信号Scombine＝m1S1+m2S2In one embodiment, the pulse oscillation wave signals collected by the first sensor and the second sensor are fused according to a preset weight ratio, and the user's blood pressure value is calculated according to the fused pulse oscillation wave signal. For example, the pulse oscillation wave signal collected by the first sensor is the first signal (S1), the pulse oscillation signal collected by the second sensor is the second signal (S2), and the weight of the first signal is m1, and the weight of the second signal is m1. The weight of the channel signal is m2, then the fused pulse oscillation wave signal Scombine=m1S1+m2S2

在另一种实施方式中，将所述第一传感器与所述第二传感器采集的脉搏振荡波信号根据加和平均法进行融合，根据融合后的脉搏振荡波信号计算用户的血压值。例如，第一传感器采集的脉搏振荡波信号为第一路信号(S1)，第二传感器采集的脉搏振荡波信号为第二路信号(S2)，融合后的脉搏振荡波信号Scombine＝(S1+S2)/2。In another embodiment, the pulse oscillation wave signals collected by the first sensor and the second sensor are fused according to the sum-average method, and the user's blood pressure value is calculated based on the fused pulse oscillation wave signal. For example, the pulse oscillation signal collected by the first sensor is the first signal (S1), and the pulse oscillation signal collected by the second sensor is the second signal (S2). The fused pulse oscillation signal Scombine=(S1+ S2)/2.

步骤S05，根据融合后的脉搏振荡波信号及压力传感器采集的压力波信号计算所述用户的血压值。Step S05: Calculate the blood pressure value of the user according to the fused pulse oscillation wave signal and the pressure wave signal collected by the pressure sensor.
