其中，如图3所示，在所述上壳体11上设置有通孔10，在所述电路主板17上设置有另一通孔170，所述第一电极片141与所述第二电极片142均设有引脚31，两个引脚31通过所述上壳体11的通孔10以及所述电路主板17上的通孔170将所述两个电极片141,142与所述电路主板17连接，以便所述电路主板获取两个电极片所采集的心电数据。另外，所述两个电极片的材质为铜镀金或铜镀镍。

另外，为了进一步增大手指与镜片的接触面积，所述发光镜片与反射镜片为表面均匀凸起的镜片，从而进一步增加手指血氧信号的采集量。
另外，图1所示的测量设备中，所述按键18，用于在受控于一次按压后启动对用户的心电数据与血氧数据进行获取或停止对用户的心电数据与血氧数据进行获取。也就是说，当所述测量设备处于关闭状态时，按下按键18则开启所述测量设备；若是所述测量设备处于开启状态，按下按键18则关闭所述测量设备。

为了便于携带所述测量设备，所述测量设备还可包括通孔(图中未示)，设置在所述测量设备的任意一个侧面，用于拴挂所述测量设备。例如，用于拴钥匙链，便于携带，随时测量。
通过本公开实施例，将血氧测量设备与心电测量设备集成在一起，通过一次测量即可同时采集到同一时刻的血氧数据和心电数据，从而可以实现通过血氧数据与心电数据得到血压值。
结合上述图1-图7的测量设备，图8是本公开实施例提供的根据如上所述的测量设备的测量方法的流程示意图。如图8所示，所述方法包括如下步骤：
步骤801，同时获取红外光PPG波形数据、血氧数据以及心电数据；

其中，当用户左右手指分别同时按住图2所示的测量设备上的第一电极片与第二电极片时，即可同时获取红外光PPG波形数据、血氧数据以及心电数据。
其中，所述指定时间值为在所述心电与脉搏波峰组中的所述心电波峰值对应的时间与所述脉搏波峰值对应的时间之间，所述红外光PPG波形数据中的最大值、最小值、一阶导数、二阶导数或切点值对应的时间。另外，所述一阶导数是所述红外光PPG波形数据中相邻的两个数据之间的差值中 的最大值。所述二阶导数是相邻两个所述差值之差中的最大值，也就是在计算一阶导数之后，将所得到的所有差值中的相邻两个差值再作差得到的最大值为二阶导数。
然后，根据第一预设参数、第二预设参数以及所述指定时间值，得到每个所述心电与脉搏波峰组对应的血压值。在计算所述血压值BP的过程中，本公开实施例可采用如下三种公式中的任意一种：


BP＝a＝ln(PAT)+b               公式(3)
其中，PAT为所述指定时间值，a为所述第一预设参数，b为所述第二预设参数。
另外，所述血压值包括舒张压和收缩压，因此，对应的第一预设参数与第二预设参数也针对舒张压和收缩压分别设置，即所述第一预设参数包括舒张压第一预设参数和收缩压第一预设参数，所述第二预设参数包括舒张压第二预设参数和收缩压第二预设参数。在本公开实施例中，所述指定时间值最优选择一阶导数，计算血压值的公式最优选择公式(3)。
通过本公开实施例，在获取到心电数据与红外光PPG波形数据之后，即可得到血压值，相比于传统血压测量的方式，本公开实施例更加方便，即减少了测量设备的个数，又减少了用户的测量次数。同时，相比于传统血压测量方式，仅能得到一组血压值(包括舒张压和收缩压)，在本公开实施例实时获取心电数据与红外光PPG波形数据的前提下，可得到多组血压值，且可实现不间断的血压值监控。
