血压计系统及其血压测量方法
技术领域
本发明涉及一种测量血压系统， 特别涉及一种血压计系统及其血压测量方法。
背景技术
随着人们生活水平的逐步提高， 血压问题越来越为人们所关注。血压病人测量血压过程 中， 测量血压时手臂位置很重要， 如果血压计位置在心脏水平以下（坐位时手臂下垂）读数 将偏高， 如果血压计位置在心脏水平以上， 读数将偏低； 这种不同归因于流体静力学影响， 相差可达 lOmmHg或以上。 每上升或下降于心脏水平 1英寸， 血压相差 2mmHg。 现有血压计 为了解决这一问题采取的方法， 例如中国专利 200420050621. 2披露的， 因使用者测量身体 部位的姿势正确时， 与心脏在同一水平线上的手腕位置是确定的， 血压计内置有用于存储己 存数据的存储部件和用于侦测空间位置参数的位置侦测部件，其中的己存数据为使用者测量 身体部位姿势正确时的相关参数值，当侦测到的空间位置参数落入存储部的己存数据范围内 时， 则提示测量的身体部位姿势正确， 即可以开始测量， 否则通过警示单元发出警告。 上述 技术方案中， 血压计在所述空间位置参数的允许误差范围内时进行血压测量， 能够使得单次 血压测量相对准确。
但现在较多血压病患者， 需要跟踪其血压变异性（一定时间内血压波动的程度）（BPV)， BPV对血压病患者的高血压诊断、 判断用药量、 评价治疗效果和判断预后具有很重要的指导 意义， 其中涉及到早期高血压病的诊断， 协助鉴别原发性、 继发性和复杂高血压， 指导合理 用药， 更好地预防心脑血管并发症的发生， 预测高血压的并发症和死亡的发生和发展。 但 是在患者的 BPV数据采集过程中，多次血压测量的使用者测量部位姿势的相关空间位置参数 均在允许误差范围内， 但各次亦不同。 即使所述空间位置参数均在允许范围内， 因为 BPV的 指导意义在于在一段时间内血压数据的变化，使用者实际的血压数据在该时间段内可能变化 不大， 如果每次测量时使用者测量部位姿势不同， 则会对 BPV数据变化产生较大影响， 据此 BPV数据得出的对患者的指导意见将不够准确， 甚至因为此不够准确的指导意见做出错误的 高血压诊断、 判断用药量、 评价治疗效果和判断预后， 而耽误甚至加重患者的病情。 但是如
果血压计设置每次测量血压的测量部位姿势一致， 则血压计又不具有普遍的适用性。
因此， 提供一种结构简单、 设计合理、 性能可靠、 精准稳定、 操作简便的血压计系统及 其血压测量方法， 使其具有检测用户姿势并与前一次姿势进行比对的功能， 开发该系统即是 该领域技术人员需着手解决的问题之一。

以下结合附图和较佳的实施例， 对依据本发明提供的具体实施方式、 结构、 特征详述如 下：
如图 1所示， 一种血压计系统， 其特征在于该系统分为血压测量装置和移动终端； 所述血压测量装置包括：
血压测量模块， 用于感测血压变化并采集血压数据， 包括腕带、 压力传感器和血压数据 采集部；

所述姿势指示模块在血压测量过程中还用于提示用户修正手腕或手臂姿势。
采用本发明血压计系统的血压测量方法， 包括如下步骤：
血压测量装置的姿势检测模块检测用户测量部位空间位置参数，并根据检测到的用户测 量部位空间位置参数计算得出用户测量部位的空间位置数据；
血压测量端通讯模块将姿势检测模块检测并计算得出的空间位置数据传输到移动终端； 移动终端的数据管理模块接收姿势检测模块检测并计算得出的空间位置数据； 移动终端的姿势比对模块将本次血压测量前用户测量部位的空间位置数据与同一用户 上次测量时测量部位的空间位置数据进行比对；
移动终端的姿势指示模块输出本次血压测量前用户测量部位空间位置数据，以及姿势比 对模块的比对结果；
用户根据姿势指示模块输出的比对结果确定是否启动开始血压测量。
以下本发明以蓝牙腕式血压计为例进行详细说明： 本实施例中， 血压测量装置包括腕带 和血压计主体， 血压计主体中包括压力传感器和血压数据采集部， 移动终端可采用手机。
首先将腕带固定在被测用户的手腕上并将血压计主体和手机开机，再将血压计主体和手 机建立数据连接，即血压测量端通讯模块和移动终端端通讯模块启动并用于手机和血压计主
体之间的数据传输。
手机上的血压测量软件开启并启动测量过程，血压测量装置首先启动姿势检测模块进行 用户测量部位， 即手腕的空间位置参数检测。 姿势检测模块中的 3D加速度传感器开始检测 被测用户手腕的空间位置并转换为电压信号，姿势检测模块中的 AD转换单元将 3D加速度传 感器输出的电压信号转换为可以运算的数字量， 然后计算出当前手腕的空间位置数据， 即手 腕与水平面间夹角 C， 通过血压测量端通讯模块将手腕与水平面间夹角 C传输至手机。 手机 接收到血压测量装置发送的手腕与水平面间角度值 C后，将 C值传送至姿势指示模块进行显 示， 并将 C值传送至姿势比对模块， 姿势比对模块将角度值 C与被测用户上次测量时手腕 与水平面间角度值 A进行比对， 比对完成后将比对结果传送至姿势指示模块。 图 2、 图 3均 为姿势指示模块显示的姿势比对模块的比对结果， 如图 2所示， 当 A与 C间存在偏差时， 姿 势指示模块以上次测量时手腕位置为虚线显示，当前手腕位置为实线显示并配合箭头指示的 方式提示用户对手腕摆放位置进行调整； 如图 3所示， 当被测用户当前手腕与水平面间夹角 C与 A值一致时， 此时姿势指示模块上的实线与虚线重合提示用户此时进行血压测量时与上 次测量时的手腕位置一致 （A与 C相等）。 当用户启动血压测量后， 手机的数据管理单元存 储下被测用户此次测量的手腕与水平面间角度值 C。 启动血压测量后， 血压测量装置中血压 测量模块的压力传感器、 放大器、 泵、 阀开始工作， 并根据腕带内的压力变化进行收缩压、 舒张压和心率的检测。 同时， 在血压测量过程中姿势检测模块检测到的手腕与水平面间的角 度值为 C' (图中未示出）， 角度值 C' 通过血压测量端通讯模块发送到手机， 手机的姿势比 对模块收到角度值 C' 后， 与存储值 C进行比较， 当 C' 比 C变化超过正负 Γ 时， 姿势指 示模块提示用户修正手腕或手臂姿势。 当血压测量装置计算出血压数据后， 血压测量模块及 姿势检测模块停止工作，血压测量装置中的血压测量端通讯模块将检测到的收缩压、舒张压、 心率等血压数据发送到手机进行显示。
综上所述， 本发明通过 3D加速度传感器定位并配合数据显示与存储器件， 而应用于各 种类型的电子血压计， 包含有臂式、 腕式及手指式等。 本发明与现有技术相比， 用户可根据 提示采用相同的测量部位姿势进行连续多次测量，消除了因测量部位姿势不同引起的血压波 动， 从而对患者的高血压诊断、 判断用药量、 评价治疗效果和判断预后具有更好更准确的指 导意义。
上述参照实施例对该血压计系统及其血压测量方法进行详细的描述，是说明性的而不是 限定性的， 因此在不脱离本发明总体构思下的变化和修改， 应属于本发明的保护范围之内。
