【具体实施方式】
下面结合附图和实施例, 对本申请作进一步的详细描述。 特别指出的是, 以下实施例仅用于说明本申请, 但不对本申请的范围进行限定。 同样的, 以下 实施例仅为本申请的部分实施例而非全部实施例, 本领域普通技术人员在没有 作出创造性劳动前提下所获得的所有其它实施例, 都属于本申请保护的范围。
脉象检测装置实施例一:
请参阅图 1 , 图 1为本申请脉象检测装置实施例一的结构示意图, 该脉象检 测装置包括第一压力传感器 110、 第二压力传感器 120、 第三压力传感器 130、 第一弹性气嚢 111、 第二弹性气嚢 121、 第三弹性气嚢 131以及处理器 140。
具体而言, 第一、 第二、 第三压力传感器间隔设置并分别对应人体脉搏的
寸、 关、 尺三个脉位, 三个压力传感器受力相互独立。 三个弹性气嚢分别套设 在第一、 第二、 第三压力传感器的外周, 三个压力传感器分别置于三个弹性气 嚢的封闭空间内, 当弹性气嚢受到外力 (脉搏压力) 时发生弹性形变, 导致其 密闭空间内的气体压力发生变化, 压力传感器通过敏感该气体压力的值以间接 测得外力的值。
处理器 140与第一、 第二、 第三压力传感器分别电连接, 并根据第一压力 传感器 110、第二压力传感器 120和第三压力传感器 130测得的压力进行脉象分 优选地, 脉象检测装置还包括柔性电路板 150, 三个压力传感器相互间隔地 贴装在柔性电路板 150 的一侧, 为了保证压力传感器受力的独立性, 柔性电路 板 150相邻的压力传感器之间开有分割线, 分割线的长度根据压力传感器的安 装尺寸确定, 一般为 8-12mm, 其宽度则通过压力传感器的间隔距离以及压力传 感器的安装尺寸共同决定, 可以设置为 0.1 ~ 0.5mm。 各相邻压力传感器的间隔 距离则根据人体腕部的寸、 关、 尺三个脉位的间距进行设置。 处理器 140则设 置在柔性电路板 150的另一侧。
优选地, 三个弹性气嚢均呈凸半球形, 以便能够与人体手腕部的动脉位很 好地接触, 当然, 弹性气嚢的形状不限于此, 能够起到与人体手腕部动脉很好 地接触作用即可。 弹性气嚢可以为橡胶等软质材料制成。
在测量时, 三个弹性气嚢分别与人体肢体的寸、 关、 尺三个动脉位置 (即 动脉位置的人体表皮软组织)相贴触, 脉象检测装置接受外部压力, 如用户的 手按压力或者将脉象检测装置设置为腕带式, 由腕带自身松紧产生的压力通过 脉象检测装置作用在动脉位置上, 三个压力传感器则分别敏感到寸、 关、 尺三 个动脉位置的脉搏压力。 由于弹性气嚢与手腕的接触面积很大。 例如, 接触面 积为 5〜10mm圓周面积, 优选 8mm, 而压力传感器的受力仅仅与弹性气嚢内的 压力有关, 而与弹性气嚢表面受力的位置无关, 因此对于测量脉搏的位置精度 并不敏感, 同时对测量姿态微小的变化也不敏感。 换句话说, 在血压测量时,
并不要求作用力必须作用在压力传感器的几何中心线上, 只要压力传感器外部 的弹性气嚢能够接触到动脉处即可, 即对受力的位置和角度没有严格要求。 这 就可以在保证测量精度的情况下, 降低了对用户的操作要求。
在第一、 第二、 第三压力传感器分别检测到寸、 关、 尺三个动脉位置的压 力时, 处理器根据第一压力传感器、 第二压力传感器和第三压力传感器测得的 压力进行脉象分析。 例如, 处理器根据将第一压力传感器、 第二压力传感器和 第三压力传感器测得的压力信号通过不同比值方式得到不同组合信号, 由获得 的不同组合信号得到脉象分析结果。
优选地, 该三个压力传感器釆用灵敏度较高的压力传感器, 例如硅压阻式 压力传感器, 硅压阻式压力传感器内部包括硅片电桥、 微型机械结构、 ADC电 路、 温度传感结构及串行接口等, 其具体的原理与工作过程为本领域技术人员 所熟知, 此处不再赘述。 该传感器安装尺寸小, 比如可以小于 9 x 9mm。
在其他实施例中, 三个压力传感器可以分别釆用不同类型的压力传感器, 譬如, 柱式压力传感器、 薄膜压阻式压力传感器等, 另外, 根据本发明实施例 的需要还可以定制尺寸更小的压力传感器,使其安装尺寸可以小于 6 x 6mm。压 力传感器具体选用哪种类型此处不做限定。
通过上述方式, 本申请创新地釆用三个分别套设有弹性气嚢的压力传感器 以准确获得三个动脉位置的脉搏变化信息, 并基于三个动脉位置上准确的脉搏 变化信息分析得到准确的脉象信息。 脉象检测装置实施例二:
请参阅图 2 , 图 2为本申请脉象检测装置实施例二的结构示意图。 本实施例 与上实施例一结构基本一致, 其区别在于, 处理器 240 包括相互连接的压力获 取模块 241和脉象分析模块 242。压力获取模块 241用于在脉象检测装置接受外 部压力过程中, 同步获取第一、 第二、 第三压力传感器分别检测到寸、 关、 尺 三个动脉位置的压力, 获得连续的压力信号。 脉象分析模块 242用于根据所述
压力信号, 获得脉象信息。 具体, 该脉象分析模块 242具体包括组合单元 2421 和分析单元 2422。
作为优化实施例, 可通过釆集左右手腕的寸、 关、 尺三个脉位的压力信号 来进行脉象分析。 具体, 压力获取模块 241 在脉象检测装置佩戴于左手腕且接 受外部压力过程中, 同步获取所述第一、 第二、 第三压力传感器分别检测到左 手腕寸、 关、 尺三个动脉位置的压力, 获得在接受外部压力过程中, 第一压力 传感器检测到左手腕寸脉位产生的连续的第一左压力信号、 第二压力传感器检 测到左手腕关脉位产生的连续的第二左压力信号、 第三压力传感器检测到左手 腕尺脉位产生的连续的第三左压力信号。 同理, 在脉象检测装置佩戴在右手腕 且接受外部压力过程中, 同步获取第一、 第二、 第三压力传感器分别检测到右 手腕寸、 关、 尺三个动脉位置的压力, 获得连续的第一右压力信号、 第二右压 力信号、 第三右压力信号。
例如, 将脉象检测装置佩戴于左手腕后, 用右手将脉象检测装置握压, 压 力获取模块 241 同步釆样第一、 第二、 第三压力传感器分别感应到压力, 获得 多组第一、 第二、 第三左压力值, 其中, 所述多组第一左压力值构成在按压过 程中连续的第一压力左信号, 所述多组第二左压力值构成在按压过程中连续的 第二左压力信号, 多组第三左压力值构成在按压过程中连续的第三左压力信号。 其中, 所述同步釆样的釆样周期为 1至 10毫秒间的数值, 优选为 3毫秒, 所述 按压腕式设备的时间为大于 4秒的数值, 例如为 6秒。 由于第一、 第二、 第三 压力传感器能够敏感到对应脉位的脉搏压力, 故第一、 第二、 第三左压力信号 与对应脉位的脉搏压力相关, 故第一、 第二、 第三左压力信号能够反映出脉搏 压力在按压过程中随时间的变化情况。 通过右手握压力的变化, 从松到紧, 腕 动脉的血流从畅通到阻断, 该过程第一、 第二、 第三左压力信号分别形成三个 脉位的脉搏从松到紧的变化曲线。 同理, 在右手握压力再从紧到松开时, 腕动 脉的血流又从阻断到畅通。 该过程可获得三个脉位的脉搏从紧到松开的变化曲 线。 同理, 将脉象检测装置佩戴于右手腕后, 用左手将脉象检测装置握压, 压
力获取模块 241 同步釆样第一、 第二、 第三压力传感器分别感应到压力, 获得 第一、 第二、 第三右压力信号。
脉象分析模块 242对第一、 第二、 第三左压力信号、 第一、 第二、 第三右 压力信号间进行比值处理, 获得多种组合的相对脉搏压力信号, 有相对脉搏压 力信号实现脉象分析。 例如, 脉象分析模块 242的组合单元 2421釆用相对值的 方式对该 6个脉搏压力信号进行比值, 例如脉搏瞬时值 /脉搏平均值。
具体如组合单元 2421将第一、 第二、 第三左压力信号、 第一、 第二、 第三 右压力信号中每个压力信号均与其他压力信号在按压过程中的平均压力值进行 比值, 得到 6x6=36种组合的相对脉搏压力信号。
或者, 组合单元 2421计算得到第一、 第二、 第三左压力信号的第一平均压 力信号, 第一、 第二、 第三右压力信号的第二平均压力信号, 以及第一左压力 信号、 第二左压力信号、 第三左压力信号、 第一右压力信号、 第二右压力信号、 第三右压力信号的第三平均压力信号, 将第一左压力信号、 第二左压力信号、 第三左压力信号、 第一右压力信号、 第二右压力信号、 第三右压力信号、 第一 平均压力信号、 第二平均压力信号、 第三平均压力信号分别与其他每个压力信 号经处理获得的数值作比值, 获得 36种组合的相对脉搏压力信号。 具体组合方 式如下表 1 , 表中列数据由上至下分别为腕戴者左手寸、 关、 尺、 右手寸、 关、 尺三个动脉位置的压力信号、 左手寸、 关、 尺三个脉位的第一平均压力信号 ∑Fn (t) . 右手寸、 关、 尺三个脉位的第二平均压力信号 ¾^(0、 左右手寸、 关、 尺共六个脉位的第三平均压力信号 | „(0 , 其中^ (0表示第 η压力信号。 表中 行数据分别为上述 9个压力信号经处理后的数值, 例如: 表示为腕戴者左手 寸脉位的脉搏压力信号 (0中所有压力值的平均值, 表示为左手关脉位的脉 搏压力信号 (0中所有压力值的平均值, ^表示为左手尺脉位的脉搏压力信号 F3W中所有压力值的平均值, 同理, 、 ^、 ^分别表示右手寸、 关、 尺 三个动脉位置的脉搏压力信号 (0中所有压力值的平均值, 表示左手寸、关、 尺三个脉位的第一平均压力信号 t (0在按压过程中所有第一平均压力值的平
均值, 第一平均压力值即为每个时刻获得的第一、 第二、 第三左压力值的平均 值, : 表示右手寸、 关、 尺三个脉位的第二平均压力信号 „(0在按压过程中 所有第二平均压力值的平均值, 第二平均压力值即为每个 刻获得的第一、 第 二、 第三右压力值的平均值。 将 9个列数据分别与属于对应单独其他脉位或多 个脉位的行数据作比值, 获得相对值。 当然, 在其他实施例中, 下表行数据也 可不为平均值, 直接为脉搏压力信号, 在此不对组合方式作出具体限定。
如下表 1即可获得 36种组合方式, 表中打对勾表示为一种组合方式。
故在握压过程中, 根据釆样得到的 6个脉位的脉搏压力信号可得到 36种组 合的相对脉搏压力信号。 分析单元 2422对变化曲线的进一步数据分析、 识别和 分类脉搏数据的类型, 进行智能比对, 获得 16种或 28种脉象, 便于作出中医 脉诊、 对腕戴人的身体状况做出脉诊结果以及处置建议, 甚至提供连续的、 长 期的、 跟踪形式的云端服务。
在另一实施例中, 组合单元可以直接由第一、 第二、 第三、 第四、 第五、 第六压力信号按照上表组合方式得到 15种组合的相对脉搏压力信号, 分析单元 对该 15种组合的相对脉搏压力信号分析比对, 获得脉象信息。
在再另一实施例中, 如对脉象识别精确度要求不高, 测量一只手腕寸、 关、 尺三个脉位的脉搏压力信号。 该数据则有 3x3=9种组合方式。 故在握压过程中, 可得到 9种组合的相对脉搏压力信号。 其中, 根据不同组合的相对脉搏压力信 号可获得不同的脉象。 处理器对相对脉搏压力信号的进一步数据分析、 识别和 分类脉搏数据的类型, 进行智能比对, 获得多种脉象, 便于作出中医脉诊、 对 腕戴人的身体状况做出脉诊结果以及处置建议。
相对现有脉象测量仪来说更加简便, 本申请还进一步釆用相对值算法, 使 得得到的测量结果对压力的方法上的差异, 以及测量中压力扰动并不敏感, 其 差异和扰动能够被相对数据的分子和分母所抵消或均化。 脉象检测装置实施例三:
请参阅图 3 , 图 3为本申请脉象检测装置实施例三的结构示意图。 本实施例 与上实施例二结构基本一致, 其区别在于, 处理器 340包括血压检测模块 343。
压力获取模块 341 还用于在脉象检测装置未接受外部压力过程中, 同步获 取所述第一、 第二、 第三压力传感器中至少两个压力传感器检测到的压力, 获 得连续的至少包括一个脉搏周期的至少两个压力信号。
血压检测模块 343包括计算单元 3431、第一获得单元 3432和第二获得单元 3433。 计算单元 3431用于根据至少两个压力信号的峰值或谷值的差值以及所述 至少两个压力传感器对应脉位之间距离计算得到脉位血压随脉位与心脏间距离 的衰减关系; 第一获得单元 3432用于在接受外部压力过程中检测到的压力信号 获得对应脉位的高、 低血压值; 第二获得单元 3433用于根据衰减关系、 对应脉 位的高低血压值, 得到心脏的高、 低血压。
例如, 压力获取模块 341 获取第一、 第二、 第三压力传感器在未按压下检 测到的第一、 第二、 第三压力信号, 此时, 未按压下检测到的第一、 第二、 第 三压力信号即分别为寸、 关、 尺三个脉位的脉搏压力信号。 计算单元 3431获得 寸、 关、 尺三个脉位的脉搏压力信号的峰值间的差值或者谷值间的差值, 根据
该差值和寸、 关、 尺三个脉位之间距离计算得到脉位血压随脉位与心脏间距离 的衰减关系。 第一获得单元 3432由在接受外部压力过程中检测到的压力信号获 得对应脉位的高、 低血压值, 例如, 查找按压过程中的第一、 第二或第三压力 信号所形成的曲线上的两个最平稳的平台, 获取该两个曲线平台上对应的压力 值, 其中较大的压力值为高血压值, 较小的为低血压值。 第二获得单元 3433用 于根据衰减关系、 对应脉位的高低血压值, 得到心脏的高、 低血压。
区别于现有技术中获得动脉位置血压后, 釆用固定预设值换算为心脏血压 值, 本实施例通过在未接受按压时获取脉搏压力信号, 从而动态地计算得到动 脉位置于心脏处血压的衰减关系, 能够灵活得出每个人动脉位置与心脏血压的 衰减关系 , 使得测量结果更精确。 脉象检测装置实施例四:
请参阅图 4, 图 4为本申请脉象检测装置实施例四的结构示意图。作为进一 步优化实施例, 该脉象检测装置的所述第一、 第二、 第三压力传感器具体为三 个下压力传感器 410,每个下压力传感器 410均背对背设置有上压力传感器 460。 本实施例中,上压力传感器 460与下压力传感器 410分别设置在柔性电路板 450 相背两侧, 该上压力传感器 460敏感外部压力值(本申请也称为上压力), 下压 力传感器 410通过弹性气嚢 411检测到相应脉位的下压力值, 其中该下压力为 上压力的反作用力和该脉位自身产生的脉搏压力的合力, 故背设的下、 上压力 传感器检测到的压力之间的差值或比值即为脉位的脉搏压力或者脉搏相对压 力。
处理器 440在脉象检测装置接受外部压力过程中, 同步获取所述三个下压 力传感器 410分别检测到寸、 关、 尺三个动脉位置的压力, 获得三个连续的下 压力信号, 同时同步获取所述三个上压力传感器 460分别检测到的上压力, 获 得三个连续的上压力信号。 处理器 440将每组背设的下、 上压力传感器分别检 测到的下压力信号与上压力信号之间的差值或比值作为该脉位的脉搏压力信号
(或脉搏相对压力信号), 获得寸、 关、尺三个脉位的脉搏压力信号,处理器 440 根据该寸、 关、 尺三个脉位的脉搏压力信号分析得到脉象信息, 其中分析方法 如上面实施例中, 处理器根据三个该下压力传感器检测到的压力信号分析得到 脉象信息的方法, 在此不作赘述。
可选地, 在另一实施例中, 处理器还可根据其中一组背设下、 上压力传感 器检测到的下压力信号和上压力信号间的差值或者比值计算人体的收缩压和舒 张压。 例如, 处理器获取在接受外部压力, 且该外部压力增大过程中的差值最 接近 0或者比值最接近 1 的两个时刻所对应的两个上压力值, 或者获取在接受 外部压力, 且该外部压力减小过程中的差值最接近 0或者比值最接近 1 的两个 时刻所对应的两个上压力值, 由该两个上压力值中的较大值得到收缩压, 由较 小值得到舒张压。 具体, 处理器将该两个上压力值中的较大值作为手腕处的收 缩压, 将较小值作为手腕处的舒张压, 通过脉位血压随脉位与心脏间距离的衰 减关系, 计算得到心脏处的收缩压、 舒张压。
其中, 该上压力传感器外周同样可以套设有上弹性气嚢, 上弹性气嚢和上 压力传感器的材质、 结构以及相互配合的原理与上述三组相似, 此处不再赘述。 值得一提的是, 上弹性气嚢的弹性系数可以比下弹性气嚢的弹性系数要大, 相 差 20-50倍,使套有弹性系数大的上弹性气嚢的上压力传感器的动态响应比套有 弹性系数小的下弹性气嚢的下压力传感器低。 通过上、 下压力传感器外均套设 有弹性气嚢, 可以使上压力传感器的测量数据也更加准确, 同时也对上压力传 感器起到很好的保护作用。 脉象检测装置实施例五:
请参阅图 5 , 图 5为本申请脉象检测装置实施例五的结构示意图。作为前述 实施例的进一步拓展, 该脉象检测装置还可以包括均与处理器 540连接的显示 器 571、操作键 572、语音提示模块 573、通讯模块 574、 I/O接口 575和壳体 576。
其中, 处理器 540以及第一、 第二、 第三压力传感器固定设在壳体 576的
内部, 且第一、 第二、 第三弹性气嚢则突出于壳体 576 的下表面, 以便在按压 过程中, 第一、 第二、 第三弹性气嚢能够接触到人体手腕部的脉位。
显示器 571设于壳体 576的上表面, 用于显示相关数据信息, 优选液晶或 者 LED屏作为显示器 576。
操作键 572则设在壳体 576的侧边或者上表面, 用于对该脉象检测装置进 行相关操作控制命令的输入, 操作键 572 的数量可以为一个或多个, 且设置位 置也不限为侧边或上表面, 此处对操作键 572的数量和设置位置不做限定。
语音提示模块 573 , 如扬声器, 可以发出操作过程及测试结果的语音提示, 方便用户使用, 增强人机交流体验。
通讯模块 574优选釆用无线通讯的形式, 具体可以为蓝牙模块、 无线网络 模块或 NFC近场通讯模块等,当然通讯模块 574也可釆用有线通讯,如通过 USB 接口或者以太网接口与外部终端通信。 该通讯模块 574还可设置有唯一的设备 标识 (ID ) 号, 用户可以通过录入个人信息的形式进行设置个人账号, 通讯模 块 574则可以将对应 ID号和该脉象检测装置测量得到的数据信息发送到远程服 务器或移动终端上, 以便对数据进一步分析及存储。 其中, 录入个人信息的形 式又可以为输入用户姓名或通过指紋识别装置输入用户指紋等。
I/O接口 575则主要用于该脉象检测装置与外部设备的有线连接, 譬如可以 通过 USB接口连接到计算机上进行数据的传输, 通过充电接口对脉象检测装置 充电等, 在本领域技术人员的理解范围内, 此处不再详述。
通过对上述两个实施例的脉象检测装置功能进一步优化, 使该脉象检测装 置功能更加完善, 同时兼容性及实用性更强。 当然, 在其他实施例中, 脉象检 测装置也可以只包括显示器、 操作键、 语音提示模块、 通讯模块、 I/O接口和壳 体的一项或多项。 脉象测量方法实施例一:
请参阅图 6, 图 6为本申请脉象测量方法实施例一的流程图。 本实施例中的
脉象测量装置如上面实施例所述的脉象测量装置, 在此不作赘述。 本脉象检测 方法包括以下步骤:
步骤 S601 : 在脉象检测装置接受外部压力时, 所述脉象检测装置间隔设置 的第一、 第二、 第三压力传感器分别通过检测到所述第一、 第二、 第三弹性气 嚢内的气体压力, 间接得到人体脉搏的寸、 关、 尺三个脉位的脉搏压力。
步骤 S602: 脉象检测装置根据第一压力传感器、 第二压力传感器和第三压 力传感器测得的压力进行脉象分析。
在第一、 第二、 第三压力传感器分别检测到寸、 关、 尺三个动脉位置的压 力时, 脉象检测装置的处理器根据第一压力传感器、 第二压力传感器和第三压 力传感器测得的压力进行脉象分析。 例如, 处理器根据将第一压力传感器、 第 二压力传感器和第三压力传感器测得的压力信号通过不同比值方式得到不同组 合信号, 由获得的不同组合信号得到脉象分析结果。 脉象测量方法实施例二:

例如, 可通过釆集左右手腕的寸、 关、 尺三个脉位的压力信号来进行脉象 分析。 将脉象检测装置佩戴于左手腕后, 用右手将脉象检测装置握压, 脉象检 测装置的处理器同步釆样第一、 第二、 第三压力传感器分别感应到压力, 获得 多组第一、 第二、 第三左压力值, 其中, 所述多组第一左压力值构成在按压过 程中连续的第一压力左信号, 所述多组第二左压力值构成在按压过程中连续的 第二左压力信号, 多组第三左压力值构成在按压过程中连续的第三左压力信号。 其中, 所述同步釆样的釆样周期为 1至 10毫秒间的数值, 优选为 3毫秒, 所述 按压腕式设备的时间为大于 4秒的数值, 例如为 6秒。 由于第一、 第二、 第三 压力传感器能够敏感到对应脉位的脉搏压力, 故第一、 第二、 第三左压力信号 与对应脉位的脉搏压力相关, 故第一、 第二、 第三左压力信号能够反映出脉搏 压力在按压过程中随时间的变化情况。 通过右手握压力的变化, 从松到紧, 腕 动脉的血流从畅通到阻断, 再从紧到松开时, 腕动脉的血流又从阻断到畅通。 该过程可获得三个脉位的脉搏的变化曲线。 同理, 将脉象检测装置佩戴于右手 腕后, 用左手将脉象检测装置握压, 处理器同步釆样第一、 第二、 第三压力传 感器分别感应到压力, 获得第一、 第二、 第三右压力信号。
步骤 S704: 脉象检测装置根据所述压力信号分析获得脉象信息。
具体, 脉象检测装置的处理器对第一、 第二、 第三左压力信号、 第一、 第 二、 第三右压力信号间进行比值处理, 获得多种组合的相对脉搏压力信号, 有 相对脉搏压力信号实现脉象分析。 例如, 处理器釆用相对值的方式对该 6个脉 搏压力信号进行比值, 例如脉搏瞬时值 /脉搏平均值。
具体如处理器将第一、 第二、 第三左压力信号、 第一、 第二、 第三右压力 信号中每个压力信号均与其他压力信号在按压过程中的平均压力值进行比值, 得到 6x6=36种组合的相对脉搏压力信号。
或者, 处理器计算得到第一、 第二、 第三左压力信号的第一平均压力信号, 第一、 第二、 第三右压力信号的第二平均压力信号, 以及第一左压力信号、 第 二左压力信号、 第三左压力信号、 第一右压力信号、 第二右压力信号、 第三右
压力信号的第三平均压力信号, 将第一左压力信号、 第二左压力信号、 第三左 压力信号、 第一右压力信号、 第二右压力信号、 第三右压力信号、 第一平均压 力信号、 第二平均压力信号、 第三平均压力信号分别与其他每个压力信号经处 理获得的数值作比值, 获得 36种组合的相对脉搏压力信号。 具体组合方式如上 表 1 , 表中说明请参考上面实施例相关说明, 在此不作赘述。
故在接受外部压力过程中, 根据釆样得到的 6个脉位的脉搏压力信号可得 到 36种组合的相对脉搏压力信号。 处理器对相对脉搏压力信号的进一步数据分 析、 识别和分类脉搏数据的类型, 进行智能比对, 获得 16种或 28种脉象, 便 于作出中医脉诊、 对腕戴人的身体状况做出脉诊结果以及处置建议, 甚至提供 连续的、 长期的、 跟踪形式的云端服务。
在另一实施例中, 处理器可以直接由一、 第二、 第三左压力信号、 第一、 第二、 第三右压力信号按照上表组合方式得到 15种组合的相对脉搏压力信号, 处理器对该 15种组合的相对脉搏压力信号分析比对, 获得脉象信息。
在再另一实施例中, 如对脉象识别精确度要求不高, 测量一只手腕寸、 关、 尺三个脉位的脉搏压力信号。 该数据则有 3x3=9种组合方式。 故在握压过程中, 可得到 9种组合的相对脉搏压力信号。 其中, 根据不同组合的相对脉搏压力信 号可获得不同的脉象。 脉象测量方法实施例三:
请参阅图 8 , 图 8为本申请脉象测量方法实施例三的流程图。 本实施例中的 脉象测量装置如上面实施例所述的脉象测量装置, 在此不作赘述。 本脉象检测 方法与上实施例一、 二的步骤基本一致, 其区别在于, 该方法还包括以下步骤: 步骤 S801 : 在脉象检测装置未接受外部压力过程中, 脉象检测装置同步获 取所述第一、 第二、 第三压力传感器中至少两个压力传感器检测到的压力, 获 得连续的至少包括一个脉搏周期的至少两个压力信号。
步骤 S802: 脉象检测装置根据所述至少两个压力信号的峰值或谷值的差值
以及所述至少两个压力传感器对应脉位之间距离计算得到脉位血压随脉位与心 脏间距离的衰减关系。 例如, 脉象检测装置的处理器获取第一、 第二、 第三压力传感器在未按压 下检测到的第一、 第二、 第三压力信号, 此时, 未按压下检测到的第一、 第二、 第三压力信号即分别为寸、 关、 尺三个脉位的脉搏压力信号。 处理器获得寸、 关、 尺三个脉位的脉搏压力信号的峰值间的差值或者谷值间的差值, 根据该差 值和寸、 关、 尺三个脉位之间距离计算得到脉位血压随脉位与心脏间距离的衰 减关系。
步骤 S803 : 脉象检测装置由所述第一、 第二、 或第三传感器在接受外部压 力力过程中检测到的压力信号获得对应脉位的高、 低血压值。 如上面实施例所 述, 脉象检测装置的处理器获取第一、 第二、 或第三传感器在接受外部压力力 过程中检测到压力信号后, 根据该压力信号获得对应脉位的高、 低血压值。
例如, 脉象检测装置的处理器查找按压过程中的第一、 第二或第三压力信 号所形成的曲线上的两个最平稳的平台, 获取该两个曲线平台上对应的压力值, 其中较大的压力值为高血压值, 较小的为低血压值。 处理器用于根据衰减关系、 对应脉位的高低血压值, 得到心脏的高、 低血压。
步骤 S804: 脉象检测装置根据所述衰减关系、所述对应脉位的高低血压值, 得到心脏的高、 低血压。 例如, 脉象检测装置的处理器获得寸、 关、 尺三个脉位的脉搏压力信号的 峰值分别为 、 F2、 F3 ,寸与关、关与尺脉位间的距离为 、 L2 ,由两个比值
1 和:^ L的平均值作为脉位血压随脉位与心脏间距离的衰减关系。处理器根据所 述衰减关系、 获得的所述对应脉位的高低血压值, 计算得到心脏的高、 低血压。
在另一优化实施例中, 该脉象检测装置的所述第一、 第二、 第三压力传感 器具体为三个下压力传感器, 每个下压力传感器均背对背设置有上压力传感器。 脉象检测装置在接受外部压力过程中, 同步获取所述三个下压力传感器分别检 测到寸、 关、 尺三个动脉位置的压力, 获得三个连续的下压力信号, 同时同步
获取所述三个上压力传感器分别检测到的上压力, 获得三个连续的上压力信号。 脉象检测装置将每组背设的下、 上压力传感器分别检测到的下压力信号与上压 力信号之间的差值或比值作为该脉位的脉搏压力信号 (或脉搏相对压力信号 ), 获得寸、 关、 尺三个脉位的脉搏压力信号, 并根据该寸、 关、 尺三个脉位的脉 搏压力信号分析得到脉象信息。
其中, 该上压力传感器外周同样可以套设有上弹性气嚢, 上弹性气嚢和上 压力传感器的材质、 结构以及相互配合的原理与上述三组相似, 此处不再赘述。
需要说明的是, 在用于测量脉象或血压时, 为使测量的心跳周期更准确, 处理器的釆样周期设置为毫秒(ms ), 例如为 l〜10ms, 优选为 2ms, 手握压力 的时间为大于 4秒, 例如为 6s, 那么每条压力值在按压过程中变化曲线的数据 有 6000/2=3000点, 期间至少经历了 3 ~ 6个完整的心跳周期, 且每个心跳周期 至少有 500个釆样数据, 极大提高了心跳周期的准确度, 使得仅利用该 3 ~ 6个 心跳周期即可较精确计算出的实际心跳周期。 可见本申请的测量耗时比传统方 法几百秒, 缩短了几十倍。 故优化地, 检测时可直接釆用手握按压式向脉象检 测装置加压, 或者设置成腕带式, 直接由腕带自身压力对脉象检测装置加压, 相对于传统充气式加压, 本申请测量简单、 耗时短、 轻便而且测量结果准确, 优胜于传统充气式测量。
优于现有气泵式血压计需在降压过程中緩慢放气测得血压方法, 由于在外 部压力增大(加压)和减小 (降压)过程中外部压力等于收缩压或舒张压时均 会出现脉搏压力为 0 的情况, 本申请无需气泵加气加压, 故不会产生噪声影响 血压测量, 故本申请可以选取加压或降压中的一个过程测量血压, 或者可同时 选取加压和减压过程分别测量出两侧血压值, 通过平均值得到更为准确的血压 值。 压力传感器组件实施例:

具体, 第一通信模块 1511用于根据脉象检测装置 1510中处理器的指令与 终端 1520中的第二通信模块 1521进行通信, 以实现脉象检测装置 1510与终端 1520之间的信息交互。 第二通信模块 1521用于根据终端 1520的指令与第一通 信模块 1511通信。 其中, 该第一通信模块 1511、 第二通信模块 1521具体可以
为蓝牙、 红外、 Wifi、 或者有线通讯模块, 在此不作限定。 具体, 第一通信模块
