Description

—种血压值监测的方法及系统 - Method and system for monitoring blood pressure value Species

技术领域 FIELD

[0001] 本发明涉及人体健康监测领域,特别地涉及一种血压值监测的方法及系统。 [0001] The present invention relates to a method and system for monitoring the field of human health, particularly to a blood pressure monitoring.

背景技术 Background technique

[0002] 血压是反映心血管系统状态的重要生理参数。 [0002] Blood pressure is an important physiological parameter that reflects the state of the cardiovascular system. 特别是近年来,高血压在中老年人群中的发病率不断上升(据统计已达15%〜20% ),而且常常是引起心血管系统一些疾病的重要因素,因此血压的准确检测与报警在临床和保健工作中变得越来越重要。 Especially in recent years, the incidence of hypertension in the elderly population continues to rise (according to statistics reached 15% ~ 20%), and is often an important factor in causing a number of diseases of the cardiovascular system, so accurate detection and alarm in blood pressure clinical and health care becomes increasingly important.

[0003]目前,临床上血压测量技术可分为直接法和间接法两种。 [0003] Currently, clinical blood pressure measurement techniques can be divided into two direct and indirect methods. 直接法是有创测量方法,通过将导管插人血管内,由压力传感器获得血压值,该方法得到的血压值准确可靠,但由于操作复杂,不适用于日常的血压检测。 Invasive measurement method is a direct method by the vascular catheter insertion, the blood pressure value obtained by the pressure sensor, blood pressure value obtained by this method is accurate and reliable, but because of complicated operations and not routine blood pressure monitoring. 而间接法具备无创性,操作简单,所以应用日益广泛。 The indirect method with non-invasive, simple to operate, so widely used. 人体血压的无创血压检测方法主要有利用柯氏音的听诊法和利用袖压信号的示波法。 NIBP detection of blood pressure using Korotkoff sound mainly auscultation method and using the oscillometric cuff pressure signal.

[0004] 柯氏音听诊法是通过将袖带捆绑在受试者上臂的适当位置,以听诊器贴近肱动脉,以充放气囊向袖带增加压力直到阻断手臂的血液流动,然后充放气囊逐步降低袖带压力以恢复手臂的血液流动,在这个过程中手臂的动脉血流脉动会产生一个由小到大,再由大到小的柯氏音变换,可借助听诊器来听取柯氏音的变化以确定收缩压和舒张压。 [0004] The oscillometric cuff method is tied by the subject in place of the upper arm, close to the stethoscope brachial artery, the air bag to increase the charge-discharge until the cuff pressure to block blood flow in the arm, and then charging and discharging airbag gradually reduce the cuff pressure to restore blood flow in the arm, in the process of arterial blood flow pulsation arm will produce a small to large, and then descending korotkoff transformation, can make use of a stethoscope to hear Korotkoff sounds to determine the change in systolic and diastolic pressures. 该方法需要有经验的医护人员参与,而且通过听柯氏声来判别收缩压、舒张压,其读数受使用者听力影响,易引入主观误差,难以标准化。 This method requires an experienced medical staff involved, but also by listening to the sound of Coriolis to determine systolic blood pressure, diastolic blood pressure readings by the user hearing the impact, the introduction of subjective error prone, difficult to standardize. 以听诊法原理制成的电子血压计,虽然实现了自动检测,但仍未彻底解决其固有缺点,即误差大、重复性差、易受噪音干扰。 The electronic sphygmomanometer in principle made auscultation, although to achieve automatic detection but not yet completely solved the inherent disadvantage that large errors, poor reproducibility, susceptible to noise.

[0005] 示波法通过袖带阻断动脉血流,在放气过程中检测袖带内的气体压力振荡波,选择振荡波幅度最大点作为参考点,根据临床统计规律计算收缩压和舒张压。 [0005] The oscillometric cuff method blocked by arterial blood flow, detecting the gas pressure oscillation in the cuff during the deflation, the maximum amplitude of an oscillation point selected as the reference point, calculated in accordance with statistical laws clinical systolic and diastolic pressure . 因为示波法的收缩压和舒张压是根据临床统计规律求得,没有考虑个体的差异,因此示波法测量个体时适应性较差,而且用示波法测量血压时需要被测者保持姿势准确,突然的动作变化会影响血压的测量。 Because the oscillometric systolic and diastolic pressures are determined based on clinical statistical laws, without considering individual differences, and therefore poor adaptability individual measured oscillometric method, but also to maintain the posture of the subject when measuring the blood pressure oscillometric accurate, sudden movements change will affect the measurement of blood pressure.

[0006] 利用听诊法或示波法可以得到人体的收缩压SP和舒张压DP,将这两个血压值与成人血压分布进行比较可以判别人体的血压值是否正常,假如出现异常情况则报警。 [0006] using the auscultatory method can be human or oscillometric systolic and diastolic SP DP, the two blood pressure and the blood pressure value can be determined comparing the distribution of the blood pressure value is normal body, if abnormal, the alarm occurs. 但由于测量过程中受到的外界干扰会造成血压值的不准确,从而出现较高的误判率。 However, due to the measurement process subject to outside interference can cause inaccurate blood pressure values, which appear higher rate of false positives.

[0052] 作为一个实施例,具体包括,就对应于每一次脉冲信号的波峰点处的导数波形求斜率,由于该点是峰值点,它对应的导数波形刚好过零点,那么取出导数波形这一过零点附近的一小段区间(如30ms)线性化得到该点对应的斜率,将该点对应的斜率作为纵坐标,对应的袖压值作为横坐标描点,形成一条斜率曲线;在导数波形上寻找介于两个连续R峰之间的最大值,并确定这些最大值的横坐标,把导数波形中波峰横坐标值和ECG中R峰横坐标值相减得到的PTT值作为纵坐标,把波峰在CP信号趋势线上对应的袖压值作横坐标描点,形成一条PTT曲线。 [0052] As an example, specifically includes, on corresponding to each first derivative of the waveform at the peak point of the pulse signal seeking slope, since this point is a peak point, which corresponds to the derivative waveform just a zero crossing, then remove the derivative waveform that short interval near the zero crossing (e.g., 30ms) to give the linearization point corresponding to the slope, the slope of the corresponding point as the ordinate, the corresponding cuff pressure value as described abscissa point, forming a slope of the curve; looking in the derivative waveform maximum interposed between two consecutive R-peaks, and to determine the abscissa of the maximum value, the value of the derivative waveform PTT abscissa value and the peak in the ECG R-peak value obtained by subtracting the abscissa plotted as the ordinate, the peak in cuff pressure value corresponding to the CP signal trend line as abscissa plot points, forming a PTT curve.

[0057] 采用中间形梯形隶属函数对血压值进行模糊处理,舒张压和收缩压的隶属函数分别如下: [0057] The membership function of the intermediate trapezoidal shape obfuscate the blood pressure value, diastolic and systolic blood pressure membership functions are as follows:

Figure CN103371809AD00091

[0059] 隶属函数的选择根据成人血压的分布情况: Select [0059] The membership function of blood pressure and distribution:

[0060] (I)舒张压> 95,收缩压> 160,则为高血压; [0060] (I) diastolic blood pressure> 95, SBP> 160, compared with hypertension;

[0061] (2)90 <舒张压< 95,收缩压> 160,则血压为较高; [0061] (2) 90 <diastolic blood pressure <95 systolic blood pressure> 160, the blood pressure is high;

[0062] (3)舒张压> 95,130 <收缩压< 160,则血压为偏高; [0062] (3) diastolic blood pressure> 95,130 <systolic pressure <160, the blood pressure is high;

[0063] (4)60 <舒张压< 90,90 <收缩压< 130,则血压为正常; [0063] (4) 60 <DBP <90 and 90 <systolic pressure <130, the blood pressure is normal;

[0064] (5) 50 <舒张压< 60,收缩压< 85,则血压为偏低; [0064] (5) 50 <diastolic blood pressure <60 systolic blood pressure <85, the blood pressure is low;

[0065] (6)舒张压< 50,85 <收缩压< 90,则血压为较低; [0065] (6) diastolic blood pressure <50,85 <systolic blood pressure <90, the lower blood pressure;
