Description

连续血压测量方法、装置和设备Continuous blood pressure measuring method, device and device 技术领域Technical field
本发明实施例涉及医疗设备技术,特别涉及一种连续血压测量方法、装置和设备。Embodiments of the present invention relate to medical device technology, and in particular, to a continuous blood pressure measurement method, apparatus, and device.
背景技术Background technique
人体血压是人类在身体健康方面,尤其是心脑血管方面非常重要的参考指标,也是医务工作者进行疾病诊断的重要依据,因此,用户经常测量并掌握自己的血压,是进行保健和预防疾病的重要手段。Human blood pressure is a very important reference indicator for human health, especially cardiovascular and cerebrovascular diseases. It is also an important basis for medical workers to diagnose diseases. Therefore, users often measure and control their blood pressure, which is for health care and disease prevention. Important means.
在现有技术中,测量血压的方式有很多种,其中,利用基于脉搏波传输速度的血压计测量血压是近年来运用较多的一种方式,该方式在使用时通过从设置在指尖或其他末梢组织位置的心电传感器(Electro Cardio Graphy;简称:ECG)和光电传感器(Photo Plethysmor Graphy;简称:PPG)采集心电信号和光电体积描记脉搏信号,并根据动脉血压和脉搏波传输速度之间的关系来确定血压,当血压上升时,血管扩张,脉搏波传输速度加快,反之,脉搏波传输速度减慢。In the prior art, there are many ways to measure blood pressure, and the use of a sphygmomanometer based on pulse wave transmission speed to measure blood pressure is a method that has been used in recent years, and the method is used by being placed at a fingertip or Electrocardiographic sensors (Electro Cardio Graphy; ECG) and Photosensors (Photo Plethysmor Graphy; PPG) collect other ECG signals and photoplethysmographic pulse signals, and according to the arterial blood pressure and pulse wave transmission speed The relationship between the blood pressure is determined. When the blood pressure rises, the blood vessels expand and the pulse wave transmission speed increases. Conversely, the pulse wave transmission speed decreases.
然而,采用基于脉搏波传输速度的方式测量血压时,需要同时用心电传感器和光电传感器进行测量,不宜进行连续的血压检测。单独利用PPG进行血压推测的技术也被研究过,但是由于体动噪声、外界干扰光或汗液等噪声,会对PPG进行光电探测造成干扰,从而导致测量误差,而且如果进行连续的血压测量,则会使误差不断积累,造成连续血压测量的精确度不高。However, when measuring blood pressure based on the pulse wave transmission speed, it is necessary to measure with both the ECG sensor and the photoelectric sensor, and continuous blood pressure detection is not suitable. Techniques for estimating blood pressure using PPG alone have also been studied, but noise due to body noise, external disturbance light, or sweat may cause interference in PPG photoelectric detection, resulting in measurement errors, and if continuous blood pressure measurement is performed, The error will accumulate and the accuracy of continuous blood pressure measurement will not be high.

具体实施方式detailed description
下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。The technical solutions in the embodiments of the present invention are clearly and completely described in the following with reference to the accompanying drawings in the embodiments of the present invention. It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
图1为本发明连续血压测量方法实施例一的流程示意图。本发明实施例提供了一种连续血压测量方法,该方法可以由任意执行连续血压测量方法的装置来执行,该装置可以通过软件和/或硬件实现。本实施例中,该装置可以集成在获取设备中,其中,获取设备例如可以为移动终端或可穿戴式设备。 如图1所示,本实施例的方法可以包括:1 is a schematic flow chart of Embodiment 1 of a continuous blood pressure measurement method according to the present invention. Embodiments of the present invention provide a continuous blood pressure measurement method, which may be performed by any device that performs a continuous blood pressure measurement method, which may be implemented by software and/or hardware. In this embodiment, the device may be integrated in the acquiring device, wherein the acquiring device may be, for example, a mobile terminal or a wearable device. As shown in FIG. 1, the method in this embodiment may include:
步骤101、获取设备获取心电信号和光体积变化描记脉搏信号。Step 101: The acquiring device acquires an electrocardiographic signal and a light volume change trace pulse signal.
在本实施例中,获取设备通过心电传感器获取心电信号,并通过脉搏传感器获取光体积变化描记脉搏信号,其中,心电传感器例如可以为ECG电极。在实际应用中,通过将至少两个ECG电极放置在获取设备的不同位置以获取心电信号,例如:可以将至少两个ECG电极放置在用户左右手分别可以接触到的位置,以通过ECG电极获取用户的心电信号。对于ECG电极的数量和具体的放置位置,本发明对此不作限制。In this embodiment, the acquiring device acquires the ECG signal through the ECG sensor, and acquires the light volume change trace pulse signal through the pulse sensor, wherein the ECG sensor can be, for example, an ECG electrode. In practical applications, the ECG signals are obtained by placing at least two ECG electrodes at different positions of the acquisition device. For example, at least two ECG electrodes can be placed at positions where the left and right hands of the user can be respectively contacted to obtain through the ECG electrodes. User's ECG signal. The number of the ECG electrodes and the specific placement position are not limited by the present invention.
步骤102、获取设备根据心电信号和光体积变化描记脉搏信号确定实测血压。Step 102: The acquiring device determines the measured blood pressure according to the electrocardiographic signal and the light volume change tracing pulse signal.
在本实施例中,获取设备获取到心电信号和光体积变化描记脉搏信号之后,根据心电信号和光体积变化描记脉搏信号,共同确定出用户的实测血压。In this embodiment, after acquiring the ECG signal and the light volume change pulse signal, the acquiring device traces the pulse signal according to the ECG signal and the light volume change, and jointly determines the measured blood pressure of the user.
步骤103、获取设备根据实测血压值和确定预测血压的预估方程式,对预估方程式的系数进行校正,并根据校正后的预估方程式计算血压值。Step 103: The acquiring device corrects the coefficient of the prediction equation according to the measured blood pressure value and the prediction equation for determining the predicted blood pressure, and calculates the blood pressure value according to the corrected prediction equation.
在本实施例中,预估方程式的建立需要预先结合输入数据进行机器学习。其中,输入数据为与血压有关的参数,其包括以下至少之一:性别、体重、身高、日常脉搏、生活习惯、作息制度、心电图特征、服药状况,光体积变化描记脉搏信号的速度脉搏,加速度脉搏等。在具体地实现过程中,可以根据各参数对光体积变化描记脉搏信号进行分类,再对分类后的光体积变化描记脉搏信号进行多元回归分析,以获知各参数与血压之间的关系,从而确定出最合适的预估方程式,举例来说:在进行机器学习时,根据用户的服药状况将光体积变化描记脉搏信号进行分类,若用户没有服药,则继续根据用户的年龄分类……,最终,将光体积变化描记脉搏信号分为N类,分类之后,根据分类结果对光体积变化描记脉搏信号进行多元回归分析,得出各参数与血压之间的关系,从而得到预估方程式,即得出的计算预测血压的预估方程式为:sBPe=f(t,Ci),其中,sBPe为预测血压,t为特征量,Ci为随机因素,其用于调整回归效果。In this embodiment, the establishment of the prediction equation requires machine learning in advance in conjunction with the input data. Wherein, the input data is a blood pressure-related parameter, which includes at least one of the following: sex, weight, height, daily pulse, living habits, work schedule, electrocardiogram characteristics, medication status, light volume change, pulse pulse velocity pulse, acceleration Pulse and so on. In the specific implementation process, the pulse signal can be classified according to each parameter, and then the multivariate regression analysis is performed on the pulse signal of the classified light volume to obtain the relationship between each parameter and blood pressure, thereby determining The most suitable predictive equation, for example: when performing machine learning, classify the light volume change pulse signal according to the user's medication status, and if the user does not take the medicine, continue to classify according to the user's age... and finally, The light volume change pulse signal is divided into N categories. After classification, multiple regression analysis is performed on the pulse signal of the light volume change according to the classification result, and the relationship between each parameter and blood pressure is obtained, thereby obtaining the estimation equation. The predictive equation for calculating the predicted blood pressure is: sBPe = f(t, Ci), where sBPe is the predicted blood pressure, t is the characteristic quantity, and Ci is the random factor, which is used to adjust the regression effect.
其中,对于特征量,获取设备可以在获取到光体积变化描记脉搏信号之后,通过对该光体积变化描记脉搏信号进行微分运算来获取。在具体的实现过程中,可以通过对光体积变化描记脉搏信号进行两次微分来获取特征量, 其中,将光体积变化描记脉搏信号进行一次微分后,可以获得速度脉搏,接着进行二次微分后,可以获知加速度脉搏,继而可以获知特征量。Wherein, for the feature quantity, the acquiring device may acquire the pulse signal by performing a differential operation on the light volume change trace signal after acquiring the light volume change trace pulse signal. In a specific implementation process, the feature quantity can be obtained by performing differential differentiation on the pulse volume signal of the light volume change. Wherein, after the light volume change trace pulse signal is differentiated once, the speed pulse can be obtained, and then after the second differential, the acceleration pulse can be known, and then the feature quantity can be known.
另外,获取设备获得特征量之后,根据预先进行机器学习确定出的计算预测血压的预估方程式,便可以计算出预测血压了。Further, after the acquisition device obtains the feature amount, the predicted blood pressure can be calculated based on the estimation equation for calculating the predicted blood pressure determined by machine learning in advance.
在具体地实现过程中,如上所述,根据输入数据将光体积变化描记脉搏信号进行分类,再对分类后的光体积变化描记脉搏信号进行多元回归分析之后,相应的,获得的预估方程式也会有若干组(n),采用哪一组预估方程式进行本次血压的预测,是根据获取设备确定出的实测血压进行确定的。具体地,可以将实测血压作为平均值X,假设计算出的预测血压为Xi,其中,i为预测血压的个数(样本个数),通过计算实测血压X与预测血压Xi(样本)之间的标准方差Sn。迭代使用所有n组预估方程式,得到预测血压样本和X的标准方差Sn,若计算出的第j个预测血压对应的标准方差Sj为所有n组Sn中的最小值,则选择该组预估方程式(标准方差为Sj的)用于测量,其中,j小于或等于i。对于多元回归分析,也可以采用其他模型,本发明对此不作限制。In a specific implementation process, as described above, the light volume change trace pulse signal is classified according to the input data, and then the multivariate regression analysis is performed on the classified light volume change pulse signal, and accordingly, the obtained estimation equation is also obtained. There will be several groups (n), and which set of predictive equations to use for this blood pressure prediction is determined based on the measured blood pressure determined by the acquisition device. Specifically, the measured blood pressure can be taken as the average value X, and the calculated predicted blood pressure is assumed to be X i , where i is the predicted number of blood pressures (the number of samples), and the measured blood pressure X and the predicted blood pressure X i (sample) are calculated. The standard deviation between S n . Iteration uses all n groups estimate equation, standard deviation S n to obtain blood samples and prediction of X, if the calculated predicted blood j-th standard deviation S j corresponding to the minimum of all of n S n groups, selecting the The group prediction equation (with a standard deviation of S j ) is used for the measurement, where j is less than or equal to i. For multivariate regression analysis, other models may also be used, which are not limited by the present invention.
