Description

用于测量人体信息的装置 Means for measuring physiological information

技术领域 FIELD

[0001] 本发明涉及人体测量领域,特别地,涉及人体重量、电阻率、心电等和健康有关的信息的测量及处理。 [0001] The present invention relates to the field of anthropometry, in particular, relates to health-related information and body weight, the resistivity, such as ECG measurement and processing.

背景技术 Background technique

[0002] 具有重量传感器的人体测量设备通常可用作一种熟知的人体测量设备,这种人体测量设备包括一个两层结构的测量平台,即上壳体和下壳体。 [0002] apparatus having a body weight measuring sensor is typically used as an anthropometric known apparatus, this measuring device comprising a measuring body platform of two-layer structure, i.e., upper and lower casings. 测量平台的上壳体一般用乳制的钢板通过压制工艺而形成,从而使它的形状类似于箱子的盖子,也可由亚克力或玻璃等其他材料形成。 Measuring platform is generally the case with a steel sheet is formed by press-dairy process, so that it is shaped like a box lid, also be formed of other materials like glass or acrylic. 上壳体具有足够的机械强度,以便当使用者位于测量平台上时能传递人体的重量而无永久变形。 The housing having a sufficient mechanical strength, in order to transfer the weight of the body without permanent deformation when the user is positioned on the measurement platform. 测量平台的下壳体通常用彩色塑性树脂通过注模法而形成。 Lower case measuring platform is generally formed by injection molding with a colored plastic resin. 下壳体的形状也类似于箱子的盖子,所述上壳体和/或下壳体可设有肋或槽,所述上壳体设有用压制工艺、喷涂工艺、或电镀工艺等形成的电极,以用于测量人体电阻,然而,所述电极的作用仅在于向人体通电并通过测量人体足底的电压来测量人体的电阻,进而计算出人体的体脂率和体内含水率等数据,对于所述电极是一种无形的资源浪费,换言之,设置在所述人体测量设备上的电极还可用于测量人体的其他参数,诸如本发明中所提到的用于测量人体足底的被动电势,以获得人体心电图。 Shape of the lower housing is also similar to the lid of the box, said upper case and / or the electrode pressing process, spray process, plating process, or the like formed in the lower case may be provided with ribs or grooves, the upper housing is provided with , for measuring the body resistance, however, the electrodes are only for power and to measure the resistance of the human body by measuring voltage to the sole of the human body, and then calculate the body fat rate data of human body and the moisture content and the like, for the electrode is an invisible waste of resources, in other words, an electrode disposed on the body measurement apparatus may also be used for measuring other parameters of the body, the passive potential for measuring the human foot referred to as the present invention, to obtain human electrocardiogram.

[0003] 实际上,这些电极还可以用于在不向人体通电的情况下获取人体足底的被动生物电势信号。 [0003] In practice, these electrodes can also be used to passively acquire biopotential signals in the case of plantar no electricity to the human body. 理论上,人体任意两点之间都存在心电引起的电势差,两个电极即可实现心电测量。 In theory, there are between any two points on the human body potential difference caused by the ECG, the two electrodes can be achieved ECG measurement. 在心电测量过程中,所述电极与皮肤的接触面积对测量结果有着至关重要的影响,即所述电极与人体的接触面积越大,则连通效果越好、测得的心电信号的共模抑制比越高。 ECG measurement process, the contact area of ​​the electrode with the skin has a critical influence on the measurement results, i.e., the larger the contact area of ​​the electrode and the human body, the better the communication were measured ECG mode suppression ratio higher. 所述连通效果指的是电极与人体之间的接触电阻率,所述接触电阻率越小,则连通效果越好。 The effect refers to the communication of the contact resistance between the electrode and the human body, the smaller the contact resistance, the better the communication.

[0004] 利用两个电极测量人体心电信息的困难在于,在测量过程中,存在交流市电共模电压的干扰,一般采用"右脚驱动"的方法来消除所述干扰,从而获得一个导联的心电信号, 换言之,通常需要至少3个电极才能获得较为准确的人体的心电信息,即获得所谓的"3芯线"标准导联,这样会导致设备昂贵。 [0004] The use of two electrodes to measure the body electrocardiographic information difficult is that, in the measurement process, the presence of interference AC common mode voltage, generally use the "right driven" approach to eliminate the interference, thereby obtaining a guide ECG Union, in other words, usually takes at least three electrodes in order to obtain more accurate ECG information on the body, that is, to obtain so-called "3 wire" standard leads, this will lead to expensive equipment. 所谓"右脚驱动"机制是将人体的共模电压,经过放大和倒相之后,通过限流电阻反馈到右脚电极上,这是一个负反馈回路,将使共模电压降低, 人体的位移电流不流到地,而是流到运放的输出端,就心电放大器而言,这样就减小了共模电压的拾取。 The so-called "right drive 'mechanism is a common-mode voltage of the human body, after amplification and phase inversion feedback to the electrode through a current limiting resistor right, which is a negative feedback loop, will reduce the common mode voltage, the displacement of the body the current does not flow, but flows to the output terminal of the operational amplifier, power amplifier, to the heart, thus reducing the common mode voltage picked up.

[0005] 测量人体电阻率的重要目的之一是为了计算人体的脂肪率,尽管市面上已经出现了单独用于测量人体体脂率和体重的"体脂秤"或其他多功能的"智能秤",也有可单独用于监测心电的设备,但测量心电的设备的电极通常需要与人体心脏附近的部位保持接触,而测量人体体脂率设备的电极通常与人体足底或手部保持接触,换言之,若想同时测量人体的体脂和心电,通常需要两套独立的装置或仪器,用于测量人体体脂率的装置一般具有两个供电电极和两个测量电极,共4个电极;而如上所述,用于测量人体心电的设备则至少需要具有3个电极。 [0005] One important object of the resistivity measuring the body fat percentage is calculated for the human body, although there have been on the market for measuring individual body weight and body fat "body fat scale" or other multi-purpose "smart scale "and also monitor cardiac electrical device may be used alone, but measurement of ECG electrodes generally requires holding the device in contact with the portion near the human heart, the electrode device to measure the body fat rate is normally held with a hand or the plantar contacting, in other words, if you want to measure body fat while ECG and the body, typically require two separate devices or instruments, the means for measuring the body fat rate typically has two power supply electrodes and two measurement electrodes, a total of four electrode; and described above, for measuring cardiac electrical device body is required to have at least three electrodes. 那么,如上所述,若想同时测量人体的体脂和心电信息,则至少需要7个电极,同时还需要相应的信号放大部件、滤波部件、以及处理器部件等,导致设备成本非常昂贵,造成对于资源的一种浪费。 Then, as described above, while if you want to measure the body fat and the ECG information, at least seven electrodes, but also requires a corresponding signal amplifying means, filtering means, and a processor member, leading to very expensive equipment, for causing a waste of resources. 尽管测量人体电阻率和检测人体心电信息都是通过测量人体表皮电势来完成的,但为完成这两种目的所测量的电势具有很大差异:在测量人体电阻过程中,首先利用所述供电电极对人体通以特定恒定的电流,并通过两个测量电极测量人体的电势差,这样所获得的电势信息在发明中称为主动电势,以下简称"电压";对应地,在不对人体通以电流的情况下,可仅通过两个测量电极来测量由心电所引起的人体两个部位的电势信号进而获得电势差,这样所获得的电势信息在本发明中称为被动电势,以下简称"电势",但是,这样的定义或简称不应当理解成与物理学上定义的冲突,而只是为了体现本发明所测量物理量之间差异的标号而已。 Although the measurement of human body resistivity and electrocardiographic information detection is done by measuring the potential human skin, but with a significant difference for the completion of these two potentials measured object: the resistance in the body during the measurement, firstly the power supply electrodes on the human body through a specific constant current, and the difference between the two measuring electrodes to measure the body potential, the potential of the information thus obtained is referred to as active potential in the invention, hereinafter referred to as "voltage"; correspondingly, a current is in the right body under the circumstances, may be measured by only two measurement electrodes from the potential of the signal body two parts ECG caused then get a potential difference, the potential of the information thus obtained is called passive potential in the present invention, hereinafter referred to as "potential" However, such a definition should not be understood or simply as physically conflict with the definition, the present invention but merely to reflect the difference between the reference measured quantities only.

[0006] 实际上,当使用者站在"体脂秤"或"智能秤"上称重、测量体脂的同时,可以充分利用所述的用于测量人体电阻的4个电极中的任意两个电极来获取人体足部和/或足底部表面的被动电势信息,建立人体的心电图导联,进而获取人体的心电信息,其中,向人体通电之后所测得的电势信息称为主动电势信息,所述主动生物电势信息用于计算人体的电阻率并通过该电阻率计算得到人体的体脂率、体水率等信息;在不向人体通电的情况下从人体足底部测得的电势信息称为被动电势信息,所述被动生物电势信息可用于获取人体的心电信息并进一步获取人体的心率信息。 [0006] Indeed, when the user stands "body fat scale" or "smart scale" on the weighing, measuring body fat at the same time, you can take advantage of any two of the four electrodes for measuring the resistance of the body electrodes to obtain the human foot and / or passive potential information at the bottom surface of the foot, the establishment of ECG lead body, and further acquires electrocardiographic information of the human body, wherein the after body energization of the measured potential of the information referred to as active potential information , the active biopotential information used to calculate the resistivity of the body and through the resistor body fat rate calculated by the body information, body water rate; in the case of no electricity to the human body from the bottom of the foot as measured potential information called passive potential information, the information may be passive biopotential for acquiring electrocardiographic information and further acquires the human body's heart rate information.

[0007] 如上所述,具有重量传感器的人体测量设备之所以非常有用是因为,它可以同时测量为得出人体脂肪率所需的体重和人体电阻信息,进一步地,如果这样的人体测量设备还可以测量人的心电和心率信息,那么则可以更全面地监控人体的健康信息,实现全面的人体健康管理。 [0007] As described above, the measuring device having a body weight sensor is very useful because of the reason that it can simultaneously measure the body weight and resistance information required to derive the body fat rate, and further, if such a body measurement apparatus further you can measure the person's ECG and heart rate information, so you can more fully monitor human health information to achieve comprehensive health management.

[0008] 需要说明的是,尽管在医疗领域对于心电测量和监控有着严格的精度要求,即要求其共模抑制比不低于60dB,性能优良的心电图仪器的共模抑制比能达到100dB。 [0008] Note that, despite strict monitoring for ECG measurements in the medical field and precision, which requires common mode rejection is not less than 60dB, excellent performance electrocardiogram common mode rejection ratio can be achieved 100dB. 但是,对于用于运动前后心率监测、心电监测等目的在于健康管理和运动规划的应用而言,由于考虑到使用方便、价格亲民等因素,将监测设备的共模抑制比控制在60dB以上即可,这样的设备可以通过人体心电信息获取人体的心率信息,让运动者准确获知当前身体是否已经进入减脂运动进程,还是仍然处于热身阶段,同时可以有效监测到明显的早搏和间歇等对健康具有重大危害的异常情况。 However, before and after exercise heart rate for monitoring, ECG monitoring, etc. For the purpose of application health management and exercise plan, taking into consideration ease of use, price close to the people and other factors, the common-mode rejection ratio control monitoring equipment that is over 60dB may, such a device may obtain information by ECG human body's heart rate information, allow movement of the body accurately informed whether the current process has entered a reduced fat movement, or still in the warm-up phase, and can effectively monitor the apparent premature beats and so on intermittent unusual circumstances of great health hazard.

[0009] 需要说明的是,本发明中所提到的人体足底、足部、足底部表面等描述性语言均指人体脚部和/或足部和/或小腿部的皮肤表面,不应将这些位置狭义地理解为其字面含义所局限的部位,只要其所提供的电势信息可以满足本发明的测量目的即可。 [0009] Incidentally, in the present invention plantar mentioned, the foot, the foot bottom surface of the descriptive language, etc. are by human foot and / or foot and / or the surface of the skin of the lower leg, is not these positions should be understood to be narrowly limited to the literal meaning of the site, as long as the potential of the information they provide to meet the purpose of measurement of the present invention.
