实施例1
请结合参阅图1和图2，本申请一实施例公开了一种微型心电主机110，该微型心电主机110具有外壳111、主功能电路112、独立电源113和机端信号电极114，外壳111的外表面具有导流部111a，实现主机的微型化与便携化，并及时导流水汽而保证使用寿命及附着贴合度，提高心电感测的灵敏度与精确度。
其中，主功能电路112和独立电源113位于外壳111的内部，受到外壳111的封装保护。主功能电路112与独立电源113电性连接，由独立电源113提供主功能电路112所需的工作电能。主功能电路112可采用常见的以心电芯片为核心的心电传感处理电路，根据获取的生物电信号通过现有的心电算法(集成于心电芯片内)，即可输出心电图、心率等参数。可以理解，独立电源113包括各类电池形式，较常见地，为可充放电的锂电池。
示范性地，主功能电路112为载有所需电路结构的印制电路板，该印制电路板由泡棉118a予以绝缘地粘贴固定。请参阅图3，示范性地，主功能电路112包括主控MCU(其型号可为MSP432)、心电信号采集放大模块(ECG ASIC，其型号可为ADS1292、AD8232等)、数据存储器和外部通讯接口(I/O接口，例如电极触点)。采集获取的生物电信号，经机端信号电极114由ECG ASIC进行信号处理(例如信号放大、滤波、降噪等)后输出至主控MCU，由主控MCU计算得到所需的心电图(ECG)、心率和心率变异(HRV)等参数，并可进一步存储在数据存储器，还可进一步通过外部通讯接口和/或蓝牙模块将心电图(ECG)、心率、心率变异(HRV)等参数传输至外部设备。
其中，机端信号电极114暴露于外壳111的外表面，其数量至少为二，以便获取人体生物电信号。可以理解，机端信号电极114可直接地连接于感测对象(人体)的皮肤表面，亦可通过其他导电体(例如导电胶、其他电极等)导通于感测对象。机端信号电极114与主功能电路112电性连接，向后者传输电信号。机端信号电极114可采用金属极片、顶针电极等实现方式， 实现电性传输。
机端信号电极114的数量根据具体应用场景而设置，示范性地，其数量为二而形成单导式导联，简化导联结构。示范性地，机端信号电极114的数量为三而形成双导式导联，使得心电信号采集更为准确。示范性地，微型心电主机110还可在前述基础上具有拓展信号电极。例如，拓展信号电极可为参考输入电极，用于自感测对象采集参考信号，微型心电主机110可以借助该信号以消除获得的心电信号中的噪音，进一步提升感测精度。拓展信号电极还可为温度传感器的检测电极，用于自感测对象采集温度信息，从而为感测对象在使用本微型心电主机110时提供更为全面的生物特征信息。
其中，机端信号电极114的暴露端所在的外壳111的外表面具有前述的导流部111a。其中，导流部111a可为导流槽。示范性地，在本实施例中，导流部111a具有多个槽体结构而形成导流槽，且导流槽端部开口于外壳111(例如其中的某一周侧外表面)。示范性地，槽体结构的截面可以为U形。机端信号电极114的暴露端可分居外壳111的不同外表面上，或者，示范性地，机端信号电极114暴露于外壳111的同一侧外表面，外壳111的该侧外表面具有导流部111a。
可以理解，具有槽体结构的导流部111a的开口端部为位于其流道末端的开口部，可为一至复数个，也就是说，导流部111a的开口部的数量可以为一个，也可以为多个，在此不做限定。导流部111a的形式亦较为丰富，包括各类直槽、环槽、弯曲槽及由数者组成的复合槽，或其他蜿蜒分布形式。示范性地，导流部111a的各部分之间保持导通，形成贯通流道。其中，外壳111的周侧外表面可为外壳111接近感测对象的一侧表面所邻接的周面。示范性地，导流部111a的宽度与深度范围均为0.5mm至1.5mm(可进一步优选为0.8mm至1mm)。需要指出的是，导流部111a的宽度不能过宽也不能过窄，过窄不利于水汽流通，过宽可能导致水汽、汗滴或淋浴水在导流部111a内形成大量挂滴，同样不易排出。
外壳111的结构形式众多，示范性地，外壳111具有收容舱体111b及分 居收容舱体111b两端的耳部111c；或外壳111仅有收容舱体111b。耳部111c可使得微型心电主机110更易于固定在人体表面，且固定的更为稳固，进而使得机端信号电极114采集的信号更为稳定，检测结果更为准确。主功能电路112及独立电源113收容于收容舱体111b内，收容舱体111b保持封装。机端信号电极114位于收容舱体111b的同一侧外表面，而导流部111a设置于收容舱体111b与耳部111c中的至少一者上。
示范性地，收容舱体111b两端的耳部111c的导流部111a互为对称结构且分别具有多个相互导通的槽体结构，至少部分耳部111c的导流部111a的槽体结构的端部开口于耳部111c的周侧外表面。其中，耳部111c的周侧外表面可为耳部111c接近感测对象的一侧表面所邻接的周面。此中，导流部111a的排气口远离机端信号电极114，避免累及后者。
示范性地，位于耳部111c的导流部111a具有中心放射状分布结构。示范性地，位于耳部111c的导流部111a具有圆弧槽结构。例如，位于耳部111c的导流部111a具有中心放射圆弧槽构造，形成多圈同心分布的圆弧槽，且各圈圆弧槽之间由纵向导槽连通。
示范性地，收容舱体111b的导流部111a具有多个槽体结构，且收容舱体111b的导流部111a的多个槽体结构中的至少数者相互之间保持导通，形成部分导通或全部导通结构。
示范性地，机端信号电极114的暴露端位于收容舱体111b的同一侧外表面中部并被一闭合凸起包围，该闭合凸起内不设导流部111a。
示范性地，机端信号电极114的暴露端所在的收容舱体111b的外表面具有凸台。机端信号电极114的暴露端位于凸台的环形内部，受到后者的环形保护。位于收容舱体111b的导流部111a则设置于凸台上并端部开口于凸台的周侧外表面，且该位于收容舱体111b的导流部111a具有槽体结构。
示范性地，当导流部111a具有槽体结构而形成导流槽时，位于收容舱体111b的导流部111a与位于耳部111c的导流部111a既可保持导通，亦可相互隔断。
示范性地，微型心电主机110还具有与主功能电路112电性连接的机端开关115，用于控制微型心电主机110的工作(关闭或开启)。
示范性地，微型心电主机110还具有与主功能电路112电性连接的温度传感电极116，用于感测感测对象的体表温度(充当温度传感器)或接收温度传感器感测到的温度数据。
示范性地，微型心电主机110还具有与主功能电路112电性连接的至少一个机端功能电极117，用于增加手持座200的可拓展功能。机端功能电极117的类型根据实际需要而决定，包括数据传输电极、充电电极或其他功能所需的电极等。机端功能电极117的结构形式众多，包括顶针、触点、金属触片等类型。例如，机端功能电极117的数量为六个，其中一个机端功能电极117为地线电极(复用，同时作为充电的0极)，与另一个机端功能电极117实现对微型心电主机110的充电；另外4个机端功能电极117是SPI线电极，用于信号传输。示范性地，机端功能电极117为嵌入于圆形通孔内部的触点，圆形通孔开设于外壳111上。
