背景技术 Background technique

[0002] 随着生活水平的提高,人们对健康越来越关注。 [0002] With the improvement of living standards, people are increasingly concerned about health. 传统的以医院体检、医生诊断方式的医疗健康服务虽然仍然有着不可撼动的地位,但是人们已经不再满足于这些传统方式的服务,其中能提供基于移动通讯设备的实时生理参数测定系统最为引入注目。 Traditional hospital examination, doctors diagnosed the way of health care services, though still has not shake the position, but people are no longer satisfied with the traditional way of these services, which can provide the most compelling real-time physiological parameters of the mobile communication device based on the measurement system . 实时生理参数测定系统结合多种传感技术,能随时为人们提供生理生化参数,方便使用者及时了解生理状况,以便采取相应医疗保健措施;同时这些数据也能为医生诊疗时提供参考,以便了解患者平时的生理状况。 Real-time biometrics system combines a variety of sensor technology, ready to provide physiological and biochemical parameters for people, user-friendly and timely understanding of the physiological condition in order to take appropriate health care measures; while these data can also provide a reference for doctors diagnosis and treatment, in order to understand in patients with normal physiological conditions. 实时在线的可穿戴健康医疗设备实时采集人体的生理数据,是移动健康医疗服务行业的入口,为基于大数据分析的健康医疗服务提供了可证实科学源泉,必将成为健康医疗服务业的基础,是未来的趋势。 Real-time online health wearable medical devices real-time collection of physiological data of the human body, the health care industry is moving the entrance, providing a source of verifiable scientific data-based analysis of large health care services, will become the basis for health care services, It is the future trend. 瑞士信贷网(ABI)报告显示可穿戴技术市场规模在未来两到三年将由目前的30-50亿美元增长到300-500亿美元。 Credit Suisse network (ABI) report shows wearable technology market grew to $ 300-500 billion over the next two to 3-5 billion dollars from the current three years. ABI的数据预计到2018年可穿戴设备全球将达到4.85亿台。 ABI data is expected to wearable device worldwide by 2018 will reach 485 million units. 中国前瞻网数据显示,2012年中国可穿戴便携移动医疗设备市场销售规模达到4.2亿元,预计到2015年这一市场规模将超过10亿元,2017年中国可穿戴便携移动医疗设备市场规模接近50亿元。 China Advanced Network data show that in 2012 China wearable portable mobile medical equipment market size reached 420 million yuan, is expected by 2015 this market will more than one billion yuan in 2017 China wearable portable mobile medical equipment market size of close to 50 billion. 心率测定是可穿戴设备获取的最基本生理参数,得到此项参数主要有两种技术:光电式和心电式。 Wearable heart rate measurement is the most basic physiological parameters of the equipment acquired to obtain this parameter There are two main technologies: photoelectric and ECG style. 光电式通过表层皮肤动脉血对特定波长光吸收的变化来计算心率;心电式通过手指或皮肤测定心电曲线,从而得到心率。 Photoelectric surface of the skin through changes in arterial blood is calculated for a particular wavelength of light absorbed by the heart rate; formula ECG measurement by a finger or the skin ECG curve, to obtain the heart rate. 这两种方法都是非常经典的测定心率技术,需要设备与人体的紧密接触,并需要排除外部光、电等因素干扰,才能获取比较可靠的心率数据。 Both methods are very classic heart rate measurement technology, equipment needs close contact with the human body, and the need to exclude external factors interfere with light, electricity, etc., in order to obtain more reliable heart rate data. 但是使用可穿戴设备在线实时测定心率时,由于使用者经常处于运动状态,很难确保以上两种技术所需要的获取可靠性数据的条件。 However, when real-time online measurement of heart rate using a wearable device, since the user is often in motion, is difficult to ensure the reliability of data acquired condition of two or more techniques required. 便携式血压的测定通常有听诊法和脉搏震荡波法两种技术。 Portable measuring blood pressure and pulse rate usually auscultation method Sasser two techniques. 听诊法采用充气袖套不断加压的方式,改变动脉的血流,通过听诊器获得血流声音变化以及与充气袖套相连接流体压力计的压力来确定动脉收缩压和舒张压。 Auscultatory method using inflatable cuff pressure mode constantly changing arterial blood flow, the blood flow is obtained by changing a stethoscope sound connected to the manometer and the pressure of the inflatable cuff to determine the arterial systolic and diastolic pressure. 该方法虽被称为测量血压的金标准,但由于采用的流体压力计体积庞大,使用不方便;大部分设备还含有有毒物质水银,因为其对环境的恶劣影响而被列入需要禁用的技术。 Although this method is referred to as the gold standard for measuring blood pressure, but the use of a large volume of the manometer, inconvenient to use; most toxic substances apparatus further comprising mercury, because it is included in the technical need to disable an adverse effect on the environment . 脉搏波震荡波法在此基础上,采用压力传感器获取充气气囊内的压力,通过气囊内脉搏波产生震动曲线进行算法分析获取血压的收缩点和舒张点以替代人耳的声音判断,大大简化了设备,使用也更加便利。 Shockwave pulse wave based on this method, pressure sensor acquires pressure in the inflatable bladder, the bladder is generated by the vibration curve for the pulse wave analysis algorithm systolic and diastolic blood pressure point acquisition points to replace the human ear sound determination greatly simplified equipment, use is also more convenient. 但是这两者本质上都需要对动脉血流进行人为加压阻断,会对人体产生不适,甚至有部分人群不能适用此方法;血压数据也不能连续在线获得。 But both are essentially the need for arterial blood pressure artificially blocked, the body will produce discomfort, and even part of the population of this method can not be applied; blood pressure data can not be continuously available online. 事实上,随着人们对健康的追求越来越高,人们对随时了解生理参数如心率血压等数据有着迫切的要求;特别是对高血压后者准高血压病人,连续在线获取血压参数对他们的诊断和健康管理都是非常必须的。 In fact, as people seek more and more on health, people keep abreast of physiological parameters such as heart rate, blood pressure and other data with urgent requirements; especially the latter quasi-hypertensive patients with hypertension, blood pressure parameters for continuous online access to them diagnostic and health management is very necessary. 连续获取血压的除了医院专业测试测试设备外,人们也在研究各种便利技术和手段以供使用者随时获取血压参数:如通过测试脉搏波传输时间等确定平均血压,通过加压使得动脉中流过的血流保持恒定的恒定血容法,以及通过分析动脉博波形的方法等,这些方法或存在使用复杂,或血压数据可靠性差、或适用人群有限等缺陷。 In addition to blood pressure continuously acquired hospital specialized test equipment test, it is also convenient to study various techniques and tools for the user ready access to blood pressure parameters: mean blood pressure, as determined by the test pulse wave transmission time, so that the arterial pressure by flowing constant blood flow to maintain a constant blood volume method, and by analyzing the shape of the artery Bobo method, the presence of these methods or the use of complex, or the difference between the blood pressure data reliability, limited crowd or other defects. 这些因素限制了产品和市场的表现。 These factors limit the product and market performance. 因此,可靠便利地通过可穿戴设备获取心率、血压数据的技术和产品有着巨大的市场基础和需求。 Therefore, reliable and convenient access to the heart rate through wearable devices, blood pressure data technology and product base and has a huge market demand.

[0051] 人体动脉内血液会随着心脏的搏动而产生波动。 [0051] in human arterial blood as the heart beats will fluctuate. 在体表处,这种波动也能被感知至IJ,只是在不同的部位所能感知到的强弱有不同而已。 At the surface, this volatility can also be perceived to IJ, but there is different in different parts that can be perceived strength. 比如中医所熟悉的脉诊就是通过感知桡动脉在腕部的寸关尺等不同位置产生脉动振幅不同而实现的。 For example TCM are familiar with different pulse diagnosis is achieved by sensing the amplitude of the pulsation generated in different positions such as foot inch off the radial artery in the wrist. 事实上,动脉血管以及与之相连接毛细血管都存在与因心脏收缩和舒张而产生的动脉波,这种动脉波以接近1m/s的速度在全身传播,从大的颈动脉到指端、耳端的动脉毛细血管都以相同的节律在波动,这就是动脉波,也就是人们在体表处感知到的脉搏搏动。 In fact, arteries and capillaries connected thereto are present, the artery pulse wave close to 1m / s and the artery pulse wave propagation velocity due to systolic and diastolic generated in the body, from the large arteries of the neck to the finger, arteriocapillary ear end are at the same rhythm fluctuation, this is the artery pulse wave, it is perceived in the surface of the pulse beats. 动脉波在血管中的流动主要产生两种效应:一是动脉血液在心脏的栗压下,对动脉血管侧壁产生压力,这即通常称谓的血压;第二种效应是因为左心室在射血初期栗出的血量大,减小至舒张期的关闭不在射出血液,因此动脉内的血流容积也是随着心脏收缩舒张周期而变化的。 An artery flow in a blood vessel produces two primary effects: First, the arterial blood pressure in the heart of Li, a pressure vessel side walls of arteries, blood pressure which commonly title; second effect is because the left ventricle ejection Li the initial large amount of blood, to reduce the diastolic blood exit is not closed, and therefore also in the arterial blood volume as the systolic and diastolic cardiac cycle varies. 这两种变化统称为脉搏波,前者称为脉压脉搏波,通过压阻型、压容、或者压电型传感式脉搏传感器获取;后者称为血容脉搏波,一般通过光电式动脉容积传感器得到。 Both changes referred to as the pulse wave, the former is called pulse pressure pulse wave through the piezoresistive type pressure container, or a piezoelectric type sensing pulse sensor acquisition; the latter is called pulse wave hematocrit, typically by photoelectric artery volume obtained by the sensor. 不管是脉压脉搏波还是血容脉搏波,蕴含有大量的人体生理信息,动脉搏动的节律脉率即心率,脉搏波的波形变化和节律情况直接反映人体循环体统的健康状况,比如动脉的收缩和舒张、血管弹性、肢端微循环状况。 Whether pulse pressure wave or pulse blood volume pulse wave, it contains a large number of human physiological information, arterial pulse rhythm pulse rate, ie heart rate, waveform and pulse wave rhythms situation directly reflects the health of the human circulatory decency, such as contraction of arteries and diastolic, blood vessel elasticity, peripheral microcirculation. 人体某些的病变也会影响到脉搏波的节律和形状,比如高血压,高血脂症,这也是中医脉诊的生理和物理基础之一。 Some human disease can also affect the rhythm and shape of the pulse wave, such as hypertension, hyperlipidemia, one of which is the physiological pulse diagnosis and physical basis.

[0052] 图2是通过光电法实际测得的血容脉搏波。 [0052] FIG 2 is actually measured by a method of a photoelectric blood volume pulse wave. 可以看到血管内动脉的血量随着时间发生非常有规则的变动,这种变动周期和心脏搏动周期相同,其频率即为心率。 You can see the amount of blood in the arteries over time changed very regular, and the same period this change of heart beat cycle, its frequency is the heart rate. 在一个脉动周期内,我们还可以看到一些容积变动,对应着心脏的收缩和舒张,以及收缩和舒张期间心脏射血减慢引起的潮波。 In a pulsation cycle, we can also see some changes in volume, corresponding to the heart contraction and relaxation, as well as tidal waves caused by cardiac ejection slowed during systole and diastole. 大量的医学和生理学研究数据表明,脉搏波的波形和动脉血压有着非常强的相关性,有经验的中医通过对脉搏的细微体验来判断血压大致的高低。 A large number of medical and physiological research data show that arterial blood pressure waveform and pulse wave has a very strong correlation, an experienced Chinese medicine through subtle experience of approximately pulse to determine the level of blood pressure. 但是,这些波形变化都是相对值变化,不能直接得到量化的血压值,这就需要给这些波形参数提供一个可供参考的压力值,以量化血压值。 However, these variations are waveform change in relative value, can not be directly quantized blood pressure value, which requires providing a pressure value for a reference to the waveform parameters to quantify blood pressure value. 本发明中解决了这一难题:通过压力传感装置获取包覆在测试动脉位置的流体盛置装置内的固定流体压力来测定动脉血流对动脉血管壁产生的压力,从而使得脉搏波有了压力参考点。 The present invention solves this problem: acquiring artery pressure is measured on the arterial wall resulting fixed fluid pressure within the cover means in the test fluid filled position opposing the artery by the pressure sensing means, so that the pulse wave has pressure reference point. 由于脉搏波和流体压力波动是同步获得的,通过波形分析和关联性计算,即可确定动脉血压。 Since the pulse wave is synchronized and the fluid pressure fluctuations obtained by calculation and correlation waveform analysis, to determine arterial blood pressure.
