Description

一种可进行定标的血压测量设备及方法
本申请属于可穿戴设备技术领域，尤其涉及一种可进行定标的血压测量设备及方法。
背景技术
血压是反映用户循环系统机能的重要参数，为了避免现有电子血压计通过袖带给手臂加压带来的噪声和不舒适感，以及实现连续的血压测量，多采用脉搏波传输时间(PWTT)可获得用户的血压数值。
通常采用光电容积脉搏波(PPG)同时监测心电(ECG)和外周血管(如桡动脉)脉搏波或者身体任意两个部位(如颈动脉和桡动脉)的脉搏波，计算它们之间的时间延迟，即动脉血从心脏喷出到传输至外周血管所需要的时间，从而获得脉搏波传输时间。通过脉搏波传输时间和动脉血压之间的计算模型，计算用户的血压数值。
目前对于脉搏波传输时间和动脉血压之间的计算模型的定标方式是采用其他的设备测定被监测者的真实动脉血压水平，对脉搏波传输时间和动脉血压之间的计算模型进行定标，从而提高血压检测的准确性。
由于需要使用其他的设备对脉搏波传输时间和动脉血压之间的计算模型进行定标，从而造成操作不便，因此很多人放弃定标，从而影响血压检测的准确度。并且，在使用其他设备对脉搏波传输时间和动脉血压之间的计算模型进行定标时，可能由于设备本身所带来的系统误差或者由于设备使用者的经验，从而导致定标出现误差。

具体实施方式
通过对大量人群的研究，所述脉搏波的传输时间(PWTT)和动脉血压(BP)满足以下计算模型：
BP＝a*ln(PWTT)+b，
其中，参数a和参数b与每个人的血管特性有关，也和测量的血压是收缩压还是舒张压有关。
参数a和b的确定过程称为定标，定标的方法是通过改变所监测用户的体位使用户的血压数值发生改变，同时采用其他设备获得所监测用户的体位改变前后用户的血压数值对应的脉搏波的传输时间，通过解方程组即可以确定参数a和b。
现有技术中也存在所述脉搏波的传输时间(PWTT)和动脉血压(BP)满足的其他计算模型，比如：BP＝A*PWTT+B，
其中，参数A和参数B也与每个人的血管特性有关，也和测量的血压是收缩压还是舒张压有关。
同样，参数A和参数B的确定过程也称为定标，定标的方法同上。
本申请所述血压测量设备内部包括压力传感器和心率芯片，当所述心率芯片感测血管的光电容积脉搏波的振幅低于阈值时，所述压力传感器感测通过所述血压测量设备对血管施加的压力值即为动脉压力值，并将至少两次感测的所述压力值发送至智能便携终端以完成动脉血压值的定标。因此，本申请通过血压测量设备内置的压力传感器和心率芯片即可实现脉搏波传输时间和动脉血压之间计算模型的血压定标，无需其他设备，操作方便，且能够有效减小定标误差，提高了定标的准确度。
为使得本申请的发明目的、特征、优点能够更加的明显和易懂，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而非全部实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前 提下所获得的所有其他实施例，都属于本申请保护的范围。
参见图1，本申请实施例提供一种可进行定标的血压测量设备1，所述血压测量设备1连接智能便携终端2，所述智能便携终端2或者所述血压测量设备1中的处理器根据所述血压测量设备1发送的压力值完成动脉血压值的定标。本申请智能便携终端2可为普通的智能手机。
由于心率芯片技术为根据光电容积脉搏波的发射获取原理，将相应的硬件功能模块集成在一片细小的芯片上，其通过接收经过毛细血管吸收后剩余的反射光，得到反映血流波动的光电容积脉搏波。因此，血压测量设备通常采用内置的心率芯片检测光电容积脉搏波。
参见图2，本申请所述血压测量设备1包括：置于所述血压测量设备内部的压力传感器11和心率芯片12。
具体地，本申请通过将血压测量设备1对准前肢相应的血管111，将其压在对应的骨骼110上。由所述心率芯片12感知血管中血容量的变化，而压力传感器11感受由手指通过血压测量设备1施加的对血管111施加的压力值。其中当相应的手指通过血压测量设备1施加的对血管111的压力值小于血管111的本身的压力值时，血液能正常通过相应的血管111，其光电容积脉搏波如图3的112所示。
参见图4，当手指通过血压测量设备1施加的对血管111的压力值继续增大时，相应的血管111会越来越窄，一直到施加的压力值与血管111本身的压力值相等时，整个血管111即完全闭合。由于此时血管111已经没有了血流，因此由所述心率芯片12所监测到的光电容积脉搏波的振幅低于阈值，即脉搏波几乎变为一条直线或脉搏波呈直线，如图5所示。所述阈值为本领域技术人员根据人体特征进行设定。因此，此时由所述压力传感器11所感知到的压力值即为所监测到的血管111的动脉压力值。
当所述心率芯片12感测血管111的光电容积脉搏波的振幅低于阈值时，本申请压力传感器11感测用户通过所述血压测量设备1对血管施加的压力值，所述压力传感器11将至少两次感测的所述压力值发送至智能便携终端2以完成动脉血压值的定标。
具体地，本申请利用位于所述智能便携终端2或者所述血压测量设备1中的处理器将所述至少两次感测的所述压力值代入计算模型，通过解方程组 获得参数a和b或者A和B的值，从而完成动脉血压值的定标。
因此，本申请通过血压测量设备内置的压力传感器和心率芯片即可实现脉搏波传输时间和动脉血压之间模型的血压定标，无需其他设备，操作方便，且能够有效减小定标误差，提高了定标的准确度。
具体地，所述压力传感器11和心率芯片12位于同一平面或者不同平面。
为了防止灰尘进入所述血压测量设备1中，本申请所述血压测量设备1还包括一透明介质，所述压力传感器11嵌于所述透明介质上。
在本申请再一具体实施例中，参见图6，所述血压测量设备1为智能心率耳机，所述智能心率耳机的至少一耳塞集成所述压力传感器11和所述心率芯片12，通过所述压力传感器11和所述心率芯片12进行动脉血压值的定标。所述智能心率耳机的一个耳塞中的心率芯片12获得用户耳朵的光电容积脉搏波。所述智能心率耳机的另一耳塞设置心率芯片，将其设置在用户其他部位(比如手指)，获得用户其他部位的光电容积脉搏波。
在本申请再一具体实施例中，所述智能心率耳机的另一耳塞未设置心率芯片，在与所述智能心率耳机连接的智能便携终端2的指纹模组内集成另一心率芯片，在检测指纹时候同时检测手指处的光电容积脉搏波。
因此，本申请可利用所述智能心率耳机的至少一集成所述压力传感器11和所述心率芯片12的耳塞以及另一耳塞或者智能便携终端2的指纹模组完成定标后的血压测量。
在本申请再一具体实施例中，参见图7，与所述智能便携终端连接的所述智能心率耳机进行血压测量的过程包括：
701、所述智能心率耳机插入到所述智能便携终端的耳机插孔中。
702、利用所述智能心率耳机的一个耳塞获得用户耳朵的光电容积脉搏波，以及所述智能心率耳机的另一个耳塞或者所述智能心率耳机的指纹模组获得用户手指的光电容积脉搏波。
由于耳朵部位的毛细血管丰富，提取出来的光电容积脉搏波比其他部位如手腕处的信噪比高，受肤色、纹身、体毛和运动的影响小，通过测量耳朵和其他用户部位之间的光电容积脉搏波传输时间差，可以提高基于脉搏波传输时间监测用户血压数值的准确性以及人群适用度。将所述智能心率耳机的一个耳塞佩戴在耳朵上，所以可以通过所述耳塞上的心率芯片获得用户耳朵 的光电容积脉搏波。
因此，本申请监测的用户耳朵的光电容积脉搏波信噪比高于手腕等用户部位，提高了用户血压数值监测的准确度。并且，本申请通过智能心率耳机和智能便携终端监测用户血压值，穿戴方便，操作简单。
703、所述用户耳朵的光电容积脉搏波以及用户手指的光电容积脉搏波通过耳机线实时传输至所述智能便携终端或者所述血压测量设备中的处理器。
本申请智能心率耳机通过耳机线或者无线方式与智能便携终端连接，所述智能心率耳机可在欣赏音乐的同时，通过所述耳机线或者无线方式将所述用户耳朵的光电容积脉搏波以及用户手指的光电容积脉搏波实时传输至所述智能便携终端中的处理器。
所述智能便携终端通过所述耳机线为所述智能心率耳机供电，所述智能心率耳机的反光等所有器件的能源由所述智能便携终端提供，所述智能心率耳机无需外加电池。本申请解决了目前可穿戴设备在体积小巧和电池容量之间的矛盾。
704、判断所述智能便携终端或者所述血压测量设备中的处理器是否获得足够的光电容积脉搏波。
705、如果获得足够的光电容积脉搏波，利用所述光电容积脉搏波获得脉搏波的传输时间。
参见图8，本申请通过同步测量所述用户耳朵的光电容积脉搏波101以及其他用户部位(例如，手指)的光电容积脉搏波102，对所述光电容积脉搏波去噪，寻找到每个脉搏波的波谷点，此波谷点对应于心脏舒张末期，即将开始收缩的时刻。所述用户耳朵的光电容积脉搏波101以及其他用户部位(例如，手指)的光电容积脉搏波102的波谷点之间的延迟就是脉搏波从主动脉3传输到耳朵与脉搏波从主动脉3传输到其他用户部位(例如，手指)的时间差，即所述脉搏波的传输时间103。
706、根据每个用户定标后的计算模型，代入所述脉搏波的传输时间，得到监测的用户血压值。
707、保存所述用户血压值到智能便携终端中的相应账号中，和/或，将所述用户血压值上传至云端数据库中，以便进行血压长期管理。
智能心率耳机除了监测用户血压值外，还能检测用户的心率，血氧，体 温等数值，因此本申请智能心率耳机可实现多种用户特征监测，使用方便，操作简单。
参见图2，本申请另一实施例提供一种血压测量中的定标方法，应用于内部集成压力传感器11和心率芯片12的血压测量设备。参见图1，所述血压测量设备1连接智能便携终端2，智能便携终端2根据所述血压测量设备1发送的压力值完成动脉血压值的定标。
由于心率芯片技术为根据光电容积脉搏波的发射获取原理，将相应的硬件功能模块集成在一片细小的芯片上，其通过接收经过毛细血管吸收后剩余的反射光，得到反映血流波动的光电容积脉搏波。因此，血压测量设备通常采用内置的心率芯片检测光电容积脉搏波。
参见图8，所述方法包括：
S1、通过血压测量设备对用户血管施加压力。
S2、心率芯片感测血管的光电容积脉搏，当心率芯片感测到血管的光电容积脉搏波的振幅低于阈值时，压力传感器感测通过所述血压测量设备对血管施加的压力值。
S3、所述压力传感器将至少两次感测的所述压力值发送至处理器。
S4、所述处理器根据两次感测的所述压力值进行计算，以完成动脉血压值的定标。
具体地，本申请通过将血压测量设备1对准前肢相应的血管111，将其压在对应的骨骼110上。由所述心率芯片12感知血管中血容量的变化，而压力传感器11感受由手指通过血压测量设备1施加的对血管111施加的压力值。其中当相应的手指通过血压测量设备1施加的对血管111的压力值小于血管111的本身的压力值时，血液能正常通过相应的血管111，其光电容积脉搏波如图3的112所示。
参见图4，当手指通过血压测量设备1施加的对血管111的压力值继续增大时，相应的血管111会越来越窄，一直到施加的压力值与血管111本身的压力值相等时，整个血管111即完全闭合。由于此时血管111已经没有了血流，因此由所述心率芯片12所监测到的光电容积脉搏波的振幅低于阈值，即几乎变为一条直线，如图5的113所示。所述阈值为本领域技术人员根据 人体特征进行设定。因此，此时由所述压力传感器11所感知到的压力值即为所监测到的血管111的动脉压力值。
当所述心率芯片12感测血管111的光电容积脉搏波的振幅低于阈值时，本申请压力传感器11感测用户通过所述血压测量设备1对血管施加的压力值，所述压力传感器11将至少两次感测的所述压力值发送至智能便携终端2以完成动脉血压值的定标。
具体地，本申请利用位于所述智能便携终端2或者所述血压测量设备1中的处理器将所述至少两次感测的所述压力值代入计算模型，通过解方程组获得参数a和b或者A和B的值，从而完成动脉血压值的定标。
因此，本申请通过血压测量设备内置的压力传感器和心率芯片即可实现脉搏波传输时间和动脉血压之间模型的血压定标，无需其他设备，操作方便，且能够有效减小定标误差，提高了定标的准确度。
