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 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 1mm 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其背部的左、 右上边角与左、 右下边 角, 又由于主体支架 102其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其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、 102 Γ , 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、 102 Γ 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 *52 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 中为示意出) 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的背面,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 的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 的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 1 13为塑料材质, 其背部粘有强力粘胶, 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 1131 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 110, 电路板上 101设置有用于贴合 容置条形电池 110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 1 131 1132分别位于的两侧电池镂空部 1012, 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 111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 113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 0.8mm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 111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 117上设置有副蜂 鸣孔 1171, 主蜂鸣孔 1029与副蜂鸣孔 1171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, 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。
