下面详细描述本发明的实施例， 所述实施例的示例在附图中示出， 其中自始至终相 同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附 图描述的实施例是示例性的， 仅用于解释本发明， 而不能理解为对本发明的限制。
实施例一
图 9为本发明心电测量装置一实施例组装结构解示意图。 如图 9所示， 本实施例 心电测量装置包括电路板 101和四个背部触摸电极，所述四个背部触摸电极具体包括背 部左反馈触摸电极 104、 背部右反馈触摸电极 105、 背部正触摸电极 108和背部负触摸 电极 109， 电路板 101包括电极电路与滤波电路， 该电极电路包括正电极、 负电极和反 馈电极， 所述正电极、 负电极和反馈电极分别与所述滤波电路连接； 所述正电极、 负电 极用于向所述滤波电路导入被测者其身体的电位变化信号；所述反馈电极用于配合所述 正电极、 负电极滤除进入所述滤波电路其前端的杂波信号； 再者， 上述背部左反馈触摸 电极 104、 背部右反馈触摸电极 105， 分别设置于电路板 101的背部的左、 右下边角， 且分别与所述反馈电极连接； 上述背部正触摸电极 108、 背部负触摸电极 109， 分别设 置于所述电路板 101的背部的左、 右上边角， 且分别与所述正电极、 负电极连接。
进一步地， 对于四个背部触摸电极的介绍， 下面主要以背部负触摸电极 109的结构 以及其与电路板 101的连接方式为例进行描述， 其中， 背部左反馈触摸电极 104与背部 负触摸电极 109为同型体、 背部右反馈触摸电极 105与背部正触摸电极 108为同型体， 背部负触摸电极 109与背部右反馈触摸电极 105、 背部正触摸电极 108为镜面对称体。 具体地， 背部负触摸电极 109包括竖直焊接部 1092、 1092 ' ， 对应地， 在电路板 101 上设置有焊孔 1011、 101 Γ ； 其中， 可将竖直焊接部 1092、 1092 ' 顶部分别嵌入焊孔 1011、 101 Γ 内， 且采用点焊的方式以使得背部负触摸电极 109与电路板 101连接， 即 通过竖直焊接部 1092、 1092 ' 可使背部负触摸电极 109连接于所述电极电路的反馈电 极。 同理， 其他背部触摸电极与电路板 101 的连接方式， 与上述背部负触摸电极 109 与电路板 101的连接方式相同， 这里不再赘述。
再进一步地， 在将本实施例的心电测量装置的背面紧贴于被测者胸口的测量方式 中， 要求背部左反馈触摸电极 104和背部正触摸电极 108搭设于被测者的右侧胸口、且 同时要求背部右反馈触摸电极 105和背部负触摸电极 109搭设于被测者的左侧胸口，从 而达到测量心电波形目的。如图 9所示， 由于本实施例心电测量装置的上述四个背部触 摸电极的外边边缘及顶角均呈圆弧倒角， 因此， 在对胸部健壮的男士、 特别是胸部较丰 满的女士进行测量时， 不再会出现类似现有装置边沿被搭接在被测者较深的乳沟两侧、 而各点状电极并不能同时接触其胸部的尴尬局面；而本实施例的设计可使得四个背部触 摸电极同时搭设在被测者较深的乳沟两侧， 不但增大了与被测者胸部的接触面积， 而且 提高了测量接触的舒适度， 实现了对这两类人群稳定、 准确测量心电波形的目的。
本实施例所提供的心电测量装置，通过四个背部触摸电极的外边边缘及顶角均呈圆 弧倒角； 背部左、 右反馈触摸电极， 分别设置于电路板的背部的左、 右下边角， 且分别 与反馈电极连接； 背部正触摸电极、 背部负触摸电极， 分别设置于电路板的背部的左、 右上边角， 且分别与正电极、 负电极连接的相关技术方案， 使得在对胸部健壮的男士、 特别是胸部较丰满的女士进行测量时，四个背部触摸电极同时搭设在被测者较深的乳沟 两侧， 实现了对这两类人群稳定、 准确测量心电波形的目的。
实施例二
图 1为本发明卡片式心电测量装置组装结构分解示意图。图 2为本发明卡片式心电 测量装置的主体支架结构示意图。结合图 1和图 2所示， 本实施例的卡片式心电测量装 置包括电路板 101、主体支架 102和背部封装。其中，所述背部封装包括一背部支架 103 和四个背部触摸电极， 具体地， 背部支架 103包括一片状本体和 6个突起 1031， 6个突 起 1031分别垂直于片状本体并均匀地分布于该片状本体边缘， 在主体支架 102上对应 6个突起 1031的位置设置有卡合该些突起 1031的盲孔， 且可通过背部支架 103扣设于 主体支架 102的背面且该些突起 1031嵌入盲孔中而将背部支架 103和主体支架 102固 定连接。 当然， 突起 1031的数量可根据实际情况进行调整， 只要满足突起 1031分别垂 直于片状本体并均匀地分布于该片状本体边缘， 且在主体支架 102上对应突起 1031的 位置设置有卡合该些突起 1031的盲孔即可。 进一步地， 背部支架 103优选金属材料， 在工艺上可通过与背部支架 103—体注塑而使背部支架 103和主体支架 102固定连接。 实践中， 若背部支架 103为单独塑料构件， 背部支架 103和主体支架 102以插接方式连 接， 容易使背部支架 103和主体支架 102 的整体结构强度难以保证； 若背部支架 103 和主体支架 102均以塑料材质而整体注塑， 那么为保证该整体结构强度， 以现有注塑工 艺条件， 这样整块面积的注塑其厚度至少保证在 lmm以上， 这无形当中会增加卡片式心 电测量装置的整体厚度； 而优选背部支架 103为金属材料， 在上述背部支架 103的结构 基础上注塑主体支架 102的构造， 不但工艺简单、背部支架 103与主体支架 102的整体 结构强度大， 而且背部支架 103的厚度可保持在 0. 3mm, 可大大降低卡片式心电测量装 置的整体厚度。
进一步地， 上述四个背部触摸电极具体包括背部左反馈触摸电极 104、 背部右反馈 触摸电极 105、 背部正触摸电极 108和背部负触摸电极 109， 且该些背部触摸电极围绕 背部支架 103并分别独立地设置于主体支架 102的背部的左、右上边角与左、右下边角， 又由于主体支架 102的背部的骨架的隔离结构，该些背部触摸电极互不接触且均与背部 支架 103不相接触； 其中， 背部左反馈触摸电极 104与背部负触摸电极 109为同型体、 背部右反馈触摸电极 105与背部正触摸电极 108为同型体，背部负触摸电极 109与背部 右反馈触摸电极 105、 背部正触摸电极 108为镜面对称体； 对于四个背部触摸电极的介 绍，下面主要以背部负触摸电极 109的结构以及其与主体支架 102的连接方式为例进行 描述， 具体地， 背部负触摸电极 109包括水平卡合部 1091、 109Γ 和竖直焊接部 1092、 1092 ' ， 在主体支架 102的背部右上外角的两边分别设置有用于卡合水平卡合部 1091、 109Γ 的卡孔 1021、 102Γ ， 在主体支架 102其内部的右上角部分分别设置有用于卡 合竖直焊接部 1092、 1092 ' 的通孔 1022、 1022 ' ， 且背部负触摸电极 109与主体支架 102通过水平卡合部 1091、 109Γ 分别嵌入卡孔 1021、 102Γ 内、 竖直焊接部 1092、 1092 ' 穿过通孔 1022、 1022 ' 而固定连接， 如图 1所示， 在电路板 101上设置有焊孔 1011、 101 Γ ， 且焊孔 1011、 101 Γ 与通孔 1022、 1022，对应设置， 在竖直焊接部 1092、 1092 ' 穿过通孔 1022、 1022 ' 的同时， 竖直焊接部 1092、 1092 ' 的顶部已分别嵌入焊 孔 1011、 101 Γ 内， 且采用点焊的方式可使得装配前原本搭设在主体支架 102上的电 路板 101， 其右上角部分已与主体支架 102的右上角部分通过背部负触摸电极 109而固 定相连。 同理， 电路板 101上其他角部分和主体支架 102的连接方式， 与上述其右上角 部分和主体支架 102的连接方式相同， 这里不再赘述。
进一步地， 在测量心电波形过程中， 为提高测量姿势的舒适度， 可将上述背部触摸 电极的外边边缘及顶角的均设置为圆弧倒角。
这里需强调地是， 卡片式心电测量装置装配前， 电路板 101 可通过主体支架 102 内各个成型且均处于同一水平面内的阶梯 1025而搭设于主体支架 102内， 并可通过圆 柱 1024、 1024 ' 与圆孔 1014、 1014' 对齐设置， 以使电路板 101在主体支架 102内边 缘定位。 进一步地， 由于电路板 101 的尺寸仅约为 82 *52mm， 加之板材略单薄 （仅 0. 8 ， 为电路板 101及的强度考虑， 对应主体支架 102上设置有中心支撑柱 1026， 中心支撑柱 1026的顶部与阶梯 1025位于同一水平面内， 因此该中心支撑柱 1026可用 于支撑电路板 101的中部， 以加强对电路板 101的保护。
进一步地， 中心支撑柱 1026的顶部也可略高于阶梯 1025， 且电路板 101背面设置 有盲孔凹槽 （图 1 中未示意出） 与中心支撑柱 1026相配合， 以抵住中心支撑柱 1026 的顶部， 进而可使得电路板 101在主体支架 102内中心定位， 电路板 101可更准确地依 附于主体支架 102内， 加强了对电路板 101的保护， 提高了装置整体的强度可靠性。 为保证本实施例卡片式心电测量装置的整体厚度设计要求， 一方面， 要求电路板 101上的电子元器件均设计在其背面，如图 1和图 2所示， 由于主体支架 102呈镂空状， 该些电子元器件可充分利用该空间，透过主体支架 102的镂空部分贴合地容置于电路板 101其背面与背部封装之间， 这里 "贴合地容置"可理解为： 焊接在电路板 101上的电 子元器件与背部封装之间间隙配合，即电子元器件焊接在电路板 101上的高度充分利用 了电路板 101其背面与背部封装之间的距离； 另一方面， 除在电路板 101其正面设置适 合拇指按压的迎面正触摸电极 106和迎面负触摸电极 107， 要求电路板 101其正面不设 计电子元器件， 需强调的是， 这里的迎面正触摸电极 106和迎面负触摸电极 107并非电 子元器件， 而只是起到增加接触手感和接触面积的金属片。
进一步地， 卡片式心电测量装置还包括用于封贴在电路板 101 其正面的强力封贴
113， 该强力封贴 113为塑料材质且背部粘有强力粘胶， 强力封贴 113上预留有用于透 露迎面正触摸电极 106和迎面负触摸电极 107的电极通孔 1 131 1132， 且为使装置整 体封装效果更佳， 强力封贴 113的厚度与迎面正触摸电极 106、 迎面负触摸电极 107的 厚度等同。为进一步确保强力封贴 113设置在电路板 101其正面的贴合度、耐久度及美 观度： 一方面要求电路板 101置于主体支架 102内部后、 电路板 101其正面与主体支架 102的正面边框位于同一水平面； 另一方面要求电路板 101其正面需平整， 前述电路板 101其正面不设计电子元器件即为满足此要求， 又， 为满足电路板 101其正面需平整： 卡片式心电测量装置还包括一条形电池 1 10， 电路板上 101设置有用于贴合容置条形电 池 1 10的电池镂空部 1012， 上述透露迎面正触摸电极 106、迎面负触摸电极 107的电极 通孔 1131 1132分别位于电池镂空部 1012的两侧， 且条形电池 110沿其长边放置于电 池镂空部 1012内， 一面抵住背部封装， 另一面与电路板 101其正面位于同一水平面； 又， 为满足电路板 101其正面需平整： 卡片式心电测量装置还包括一蜂鸣器 111和液晶 屏 （图 1和图 2 中均未示意出） ， 在主体支架 102上设置有用于贴合容置蜂鸣器 1 11 的蜂鸣槽 1027、 且设置有用于卡合液晶屏的液晶槽 1028， 该液晶槽 1028位于蜂鸣槽 1027的上方， 对应地电路板 101上设置有用于贴合容置液晶屏的液晶屏镂空部 1013 在成型的卡片式心电测量装置中， 蜂鸣器 111设置于蜂鸣槽 1027内， 且液晶屏通过液 晶屏镂空部 1013而卡合于液晶槽 1028内并由蜂鸣槽 1027支撑， 而卡合于液晶槽 1028 内的液晶屏的液晶面与电路板 101 其正面位于同一水平面， 进一步地， 强力封贴 1 13 上设置有用于透明密封上述液晶屏的窗口 1133， 以便于观察液晶屏； 又， 为满足电路 板 101其正面需平整： 以背部负触摸电极 109的结构为例， 竖直焊接部 1092 1092 ' 其顶部露出通孔 1022 1022 ' 的部分其高度限定在 0. 8 以下， 即不能超越电路板 101 的厚度， 或者， 竖直焊接部 1092 1092 ' 露出通孔 1022 1022 ' 的部分的顶部与主体 支架 102 的正面边框位于同一水平面， 同样， 对其他背部触摸电极的竖直焊接部也有类 似要求。
进一步地， 上述蜂鸣槽 1027为分瓣结构， 可以理解， 该分瓣结构的间隙用于贴合 容置连接蜂鸣器 11 1与电路板 101的线路， 以充分利用空间， 从而可避免飞线的走线再 增加卡片式心电测量装置的整体厚度。 再者， 在蜂鸣槽 1027的中心位置设有一主蜂鸣 孔 1029， 对应该主蜂鸣孔 1029， 在用于封贴背部支架 103的封贴 1 17上设置有副蜂鸣 孔 1171， 主蜂鸣孔 1029与副蜂鸣孔 1 171配合传导蜂鸣器 111所发出的声音。 再者， 上述封贴 117可用于标示卡片式心电测量装置的铭牌及各种需要标示的信息和参数。
进一步地，为保证满足本实施例卡片式心电测量装置的整体厚度设计要求，一方面， 本实施例卡片式心电测量装置所包括的充电接口 112充分利用了主体支架 102的厚度， 其连接于电路板 101， 并而设置于开设在主体支架 102侧面的充电接口通孔 1023内； 另一方面， 本实施例卡片式心电测量装置的开关系统设置于本装置的正面， 由于上述本 实施例电路板 101其正面不但要求不设计电子元器件、 而且要求需平整， 为此， 电路板 上印刷 （铜刻蚀技术） 设置有用于开关电源的第一断点环状开关 1015， 以及用于启动 测试测量的第二断点环状开关 1016， 如图 3为本发明卡片式心电测量装置的断点环状 开关结构示意图所示， 该第一断点环状开关 1015、 或第二断点环状开关 1016的具体结 构包括圆环电极 1 14和圆形电极 115， 且圆形电极 115设置于圆环电极 1 14内、 并通过 一圆形沟槽 1 16绝缘而同心设置， 进一步地， 强力封贴 113上对应于第一断点环状开关 114和第二断点环状开关 115分别设置有用于接通第一断点环状开关 1 14、 第二断点环 状开关 1 15的弹性开关 1134， 具体地， 该弹性开关 1 134为拱起状弹性片， 通过该所述 弹性片受压处于展平状态以使圆环电极 1 14与圆形电极 115而电连接。

进一步地， 由于外部电极包括多个触摸电极， 因此本实施例卡片式心电测量装置 可存在多种测量姿势。
其一， 图 6a为本发明卡片式心电测量装置一测量方式的正示图； 图 6b为本发明卡 片式心电测量装置一测量方式的后示图， 结合图 6a和图 6b， 被测者可用左、 右手的拇 指分别放置于迎面正触摸电极 106、 迎面负触摸电极 107上， 且用左、 右手的食指分别 抵住背部左反馈触摸电极 104、 背部右反馈触摸电极 105， 以完成心电波形的测量。
其二， 图 7a为本发明卡片式心电测量装置另一测量方式的正示图， 图 7b为本发明 卡片式心电测量装置另一测量方式的后示图， 结合图 7a和图 7b所示， 同样， 被测者可 用左、 右手的拇指分别放置于迎面正触摸电极 106、 迎面负触摸电极 107上， 但为更加 稳定地把持本卡片式心电测量装置， 可用左、右手的中指分别抵住背部左反馈触摸电极 104、背部右反馈触摸电极 105，且同时可用左、右手的食指按压住背部正触摸电极 108、 背部负触摸电极 109的边缘。
可以理解， 手持测量姿势并不仅限于上述两种方式， 若其满足在左手的手指接触迎 面正触摸电极 106 或背部正触摸电极 108前提下、 同时接触背部左反馈触摸电极 104 或背部右反馈触摸电极 105之一，并且右手的手指接触迎面负触摸电极 107或背部负触 摸电极 109前提下、同时接触背部左反馈触摸电极 104或背部右反馈触摸电极 105之一， 即可实现心电波形的测量。

进一步地， 由于上述实施例一中背部触摸电极的外边边缘及顶角均设置为圆弧倒 角， 因此测量姿势适于被测者对装置的把握， 使得用户把握体验感更佳。 特别地， 对于 胸口测量模式， 胸部健壮的男士及胸部较丰满的女士在测量时， 背部触摸电极的外边边 缘及顶角均设置为圆弧倒角的设计， 不但使被测者感觉舒适， 而且接触测量面积较现有 相关心电测量装置的点状接触设计大幅增加， 保证了心电波形测量的稳定性。
这里需强调的是， 本实施例卡片式心电测量装置通过电极电路中的正电极、 负电 极和反馈电极， 可对被测者实现 I 、 II、 III导联的心电波形测量方式， 由于要求被测者 其一手同时接触正电极和反馈电极， 另一手同时接触负电极和反馈电极， 因此该反馈电 极的介入使得其可配合正电极、负电极滤除进入滤波电路其前端的部分杂波信号， 提高 了心电波形的测量精度。
进一步地， 本实施例卡片式心电测量装置还包括显示部、 外部存储介质和电源。 电 源， 连接于需要供电的电子元器件， 其用于对卡片式心电测量装置进行供电。 另外， 外 部存储介质， 在插入用于放置外部存储介质的插口后与 CPU连接， 其可用于暂时存储所 测得的心电波形。 显示部， 连接于 CPU, 其由 CPU对其进行显示控制， 并用于显示 CPU 对其所输出数据。
本实施例卡片式心电测量装置， 由于外部电极包括多个触摸电极， 可实现多种测量 姿势， 以方便被测者在发生心悸或呼吸急促等需要进行测量心电波形之自觉症状时， 根 据实际情况而自由更换测量姿势。
