本发明实施例提供的上述血压计，在实际操作过程中，只需要使用者的双手分别与第一电极和第二电极接触，同时，使用者的一只手与光电传感器接触，即可测量血压，与现有的血压计相比，无需佩戴袖带，操作简单；并且，第一电极、第二电极和光电传感器嵌于盒体的表面，这样，不仅不会影响第一电极和第二电极采集心电信号以及光电传感器采集脉搏波信号，而且将第一电极、第二电极和光电传感器都集成在盒体内，可以使血压计实现小型化和便携化，从而可以满足使用者随时随地测量血压的需求。
在具体实施时，在本发明实施例提供的上述血压计中，可以在电路板上集成电性连接的处理器和放大器。具体地，第一电极和第二电极分别与放大器的两端(正负端)电性连接；光电传感器与处理器电性连接；电源与处理器、放大器、光电传感器和显示器电性连接，为处理器、放大器、光电传感器和显示器(和/或蓝牙)供电。
下面对本发明实施例提供的上述血压计的具体工作原理进行详细说明。使用者的双手分别与第一电极和第二电极接触，同时，使用者的一只手与光电传感器接触，保持一定的时间(一般为10s)，即可测量血压。在此过程中，放大器在处理器的控制下通过第一电极和第二电极采集心电信号，并将采集的心电信号发送给处理器；光电传感器在处理器的控制下采集脉搏波信号，并将采集的脉搏波信号发送给处理器；处理器接收放大器发送的心电信号和光电传感器发送的脉搏波信号，识别心电信号的峰点和脉搏波信号的峰点，将心电信号(如图5所示的曲线a所示)的峰点和脉搏波信号(如图5所示的曲线b所示)的峰点的时间差确定为脉搏传输时间(如图5所示的T所示)，将脉搏传输时间代入预先存储的血压-脉搏传输时间的方程，计算出血压值并将该血压值发送给显示器；显示器接收并显示处理器发送的血压值。
需要说明的是，在本发明实施例提供的上述血压计中，处理器中预先存储的血压-脉搏传输时间的方程，可以通过定标的方式获得。具体地，可以利用标准水银血压计测量人体的标准血压，同时利用待定标的血压计测量人体当前的脉搏传输时间，从而获得一组血压-脉搏传输时间的数据；通过测量多组血压-脉搏传输时间的数据，并对该多组数据进行线性拟合，可以获得待定标血压计的血压-脉搏传输时间的方程，将该方程输入处理器即可。
在具体实施时，在使用者使用本发明实施例提供的上述血压计测量血压时，使用者的双手分别与第一电极和第二电极接触，同时，使用者的一只手与光电传感器接触。具体地，可以选择第一电极和光电传感器与使用者的同一只手接触、第二电极与使用者的另一只手接触来进行测量；或者，也可以选择第二电极和光电传感器与使用者的同一只手接触、第一电极与使用者的另一只手接触来进行测量，在此不做限定。下面以第二电极和光电传感器与使用者的同一只手接触，第一电极与使用者的另一只手接触为例进行说明。
在一些实施方式中，在本发明实施例提供的上述血压计中，为了便于使用者的一只手同时与第二电极和光电传感器接触，如图1-图4所示，可以将第二电极6与光电传感器7嵌于盒体1的同一个侧面，即第二电极6的表面与光电传感器7的表面从盒体1的同一个侧面露出。
在一些实施方式中，在本发明实施例提供的上述血压计中，在第二电极与光电传感器嵌于盒体的同一个侧面时，如图1所示，可以将第一电极5与 第二电极6嵌于盒体1的同一个侧面，这样，第一电极5、第二电极6和光电传感器7均嵌于盒体1的同一个侧面，即第一电极5的表面、第二电极6的表面和光电传感器7的表面均从盒体1的同一个侧面露出，这样，在利用上述血压计测量血压时，使用者可以将一只手按压在第一电极5上，同时将另一只手按压在第二电极6和光电传感器7上，保持一定的时间，即可由血压计中的显示器4显示出血压值。此时，为了便于使用者观看显示器4显示的血压值，如图1所示，可以将显示器4也嵌于该侧面，这样，第一电极5、第二电极6、光电传感器7以及显示器4均嵌于盒体1的同一个侧面，即第一电极5的表面、第二电极6的表面、光电传感器7的表面以及显示器4的表面均从盒体1的同一个侧面露出。
当然，显示器的表面可以从盒体的任意一个侧面露出，具体地，可以根据实际的情况，综合考虑诸如方便使用者观看血压值以及尽量减小血压计的体积等因素，对其进行适当的调整，在此不做限定。
在一些实施方式中，在本发明实施例提供的上述血压计中，在第二电极与光电传感器嵌于盒体的同一个侧面时，如图2所示，可以将第一电极5与第二电极6分别嵌于盒体1的相对的两个侧面，即第一电极5的表面与第二电极6的表面分别从盒体1的相对的两个侧面露出，这样，可以进一步地减小血压计的体积。此时，为了便于使用者观看显示器4显示的血压值，以及尽量减小血压计的体积，如图2所示，可以将第一电极5与显示器4嵌于盒体1的同一个侧面，即第一电极5的表面和显示器4的表面均从盒体1的同一个侧面露出。
当然，在第二电极与光电传感器嵌于盒体的同一个侧面时，也可以将第一电极与第二电极分别嵌于盒体的相邻的两个侧面，即第一电极的表面与第二电极的表面分别从盒体的相邻的两个侧面露出，在此不做限定。
在一些实施方式中，在本发明实施例提供的上述血压计中，为了保证使用者的手部能够与第一电极充分接触，以保证放大器采集的心电信号的准确性，同时，为了尽可能地减小血压计的体积，使血压计实现小型化和便携化，可以将第一电极从盒体露出的表面的长度控制在15mm至25mm的范围内，将第一电极从盒体露出的表面的宽度控制在8mm至12mm的范围内，将第一电极的厚度控制在1mm至1.5mm的范围内。
在一些实施方式中，在本发明实施例提供的上述血压计中，为了保证使用者的手部能够与第二电极充分接触，以保证放大器采集的心电信号的准确性，同时，为了尽可能地减小血压计的体积，使血压计实现小型化和便携化，可以将第二电极从盒体露出的表面的长度控制在15mm至25mm的范围内，将第二电极从盒体露出的表面的宽度控制在8mm至12mm的范围内，将第二电极的厚度控制在1mm至1.5mm的范围内。
在一些实施方式中，在本发明实施例提供的上述血压计中，为了保证使用者的手部能够与光电传感器充分接触，以保证光电传感器采集的脉搏波信号的准确性，同时，为了尽可能地减小血压计的体积，使血压计实现小型化和便携化，可以将光电传感器从盒体露出的表面的长度控制在5mm至6mm的范围内，将光电传感器从盒体露出的表面的宽度控制在2mm至2.5mm的范围内，将光电传感器的厚度控制在1mm至1.5mm的范围内。
在一些实施方式中，在本发明实施例提供的上述血压计中，如图3和图4所示，还可以包括：与电路板2电性连接的第三电极8；具体地，第三电极8可以与放大器中连接第二电极6的一端电性连接，该第三电极8可以作为反馈电极，起到抑制共模干扰的作用，从而可以提高放大器采集的心电信号的准确性；并且，第三电极8与第二电极6嵌于盒体1的同一个侧面，即第三电极8的表面与第二电极6的表面从盒体1的同一个侧面露出，这样，便于使用者的一只手同时与第三电极8和第二电极6接触。
在一些实施方式中，在本发明实施例提供的上述血压计中，为了保证使用者的手部能够与第三电极充分接触，以保证放大器采集的心电信号的准确性，同时，为了尽可能地减小血压计的体积，使血压计实现小型化和便携化，可以将第三电极从盒体露出的表面的长度控制在15mm至25mm的范围内，将第三电极从盒体露出的表面的宽度控制在8mm至12mm的范围内，将第三电极的厚度控制在1mm至1.5mm的范围内。
在一些实施方式中，在本发明实施例提供的上述血压计中，如图3和图4所示，血压计还可以包括：与盒体1连接的腕带9；这样，使用者可以将血压计直接佩戴在手腕上，方便随时随地测量血压。例如，在使用如图3所示的血压计测量血压时，使用者可以将血压计从手腕上取下，将一只手按压在第一电极5上，同时另一只手按压在第二电极6、光电传感器7和第三电极8 上，保持一定的时间，即可由显示器4显示出血压值；在利用如图4所示的血压计测量血压时，使用者无需将血压计从手腕上取下，可以直接利用未佩戴血压计的手按压在第一电极5上，使第二电极6、第三电极8和光电传感器7均与佩戴血压计的手腕接触，保持一定的时间，即可由显示器4显示出血压值，这样，使得血压计的操作更加简单。需要注意的是，在佩戴如图4所示的血压计时，需要将第二电极6露出的表面、第三电极8露出的表面和光电传感器7露出的表面面向使用者的手腕。
在具体实施时，在本发明实施例提供的上述血压计中，处理器可以为ARM处理器，它可以控制信号的采集(例如，控制放大器的采样率和信号放大倍数等，控制光电传感器的采样率和发光强度等)，并实时读取和处理数据。
在具体实施时，在本发明实施例提供的上述血压计中，电源可以为可充电电池，例如，锂电池。
需要说明的是，在本发明实施例提供的上述血压计中，光电传感器优选反射式光电传感器。由于反射式光电传感器的发光管和光敏接收器都位于使用者的手部的同一侧，这样，可以将反射式光电传感器集成于盒体的内部，仅将反射式光电传感器的表面露出，从而可以保证血压计实现小型化和便携化。
需要说明的是，在本发明实施例提供的上述血压计中，并非局限于通过显示器显示血压值的结构，还可以利用蓝牙代替显示器。具体地，可以通过蓝牙将处理器计算出的血压值发送给使用者的手机或计算机，通过手机或计算机读取血压值，这样，还可以进一步地减小血压计的体积，使得本发明实施例提供的上述血压计更加小型便携。
下面以如图4所示的血压计为例，对本发明实施例提供的上述血压计的具体尺寸进行说明。根据第一电极、第二电极、光电传感器和第三电极的具体尺寸，以及电路板和锂电池的厚度一般分别为3mm和4mm，可以推知，本发明实施例提供的上述血压计的长度为35-45mm，宽度为28至35mm，厚度为9-15mm，更具体地而言，长度约为40mm，宽度约为30mm，厚度约为10mm。本发明实施例提供的上述血压计的体积小，便于携带。
本发明实施例提供的一种血压计，该血压计在实际操作过程中，只需要 使用者的双手分别与第一电极和第二电极接触，同时，使用者的一只手与光电传感器接触，即可测量血压，与现有的血压计相比，无需佩戴袖带，操作简单；并且，第一电极、第二电极和光电传感器嵌于盒体的表面，这样，不仅不会影响第一电极和第二电极采集心电信号以及光电传感器采集脉搏波信号，而且将第一电极、第二电极和光电传感器都集成在盒体内，可以使血压计实现小型化和便携化，从而可以满足使用者随时随地测量血压的需求。
