在本实施例中，相较于相关技术中将传感单元110直接通过线路连接至处理模块200，在其间设置一信号调理芯片120，并由信号调理信号控制第一线圈130进行信号收发，可以将传感单元110与处理模块200的有线连接转化成无线连接，从而减小了线路的连接长度，简化了线路的复杂性。此外，由于处理模块200与信号调理芯片120之间省去了线路连接，处理模块200不需要设置用于线路连接的连接头。因此，可以去掉了刚性补强板，省去了补强工艺，更易处理成卷工艺，因此节省了物料和工艺成本，提高了加工效率。同时大大提升了用户在 使用装配时的便利性，传感模块功能扩展方便。而且，由于第一线圈和第二线圈可以通过无线耦合的方式传输能量，在传感模块中，就可以直接由第一线圈无线接收到的能量对传感单元、信号调理芯片等器件的供电。基于上述供电方式，传感模块中可以无需设置电池等结构，从而简化了传感模块的结构，进而简化了尿不湿的整体结构。
在其中一个实施例中，当所述传感单元110包括多个传感器时，所述信号调理芯片120被配置有多个传感通道接口，各所述传感通道接口分别用于连接一个对应的所述传感器。可以理解的是，传感通道接口可以根据需求设计，因此更容易适配于传感器数量增多的情形。而且，由于信号调理芯片120的体积较小，增加传感通道接口对器件整体占用空间也不会造成太大影响。可以理解的是，当传感器数量增加以感测更多的数据时，仅需改变传感器与传感通道接口之间的连接关系即可实现兼容，方法简单且易于实施，更加利于代谢物检测装置的功能扩展。
在其中一个实施例中，所述信号调理芯片120被配置有可更新的信号调理算法，所述信号调理算法与所述传感单元110中的多个所述传感器的类型对应设置。也即，仅需在信号调理芯片120中进行信号调理算法的更新，即可实现更加丰富的信号调理功能。因此，无需更新信号调理芯片120的硬件结构，只需要进行简单的软件算法更新，就能完成产品的更新迭代。
在其中一个实施例中，所述信号调理芯片120还被配置有预设的身份标识信息。相应地，信号调理芯片120具有存储功能，以记录每一片尿不湿的身份标识信息。其中，身份标识信息包括但不限于尿不湿的ID信息等信息。其中，当所述信号调理芯片120将多个所述调理信号传输至所述第一线圈130进行发送时，所述信号调理芯片120还用于将所述身份标识信息传输至所述第一线圈130 进行发送，以使所述处理单元建立所述代谢物信息与所述身份标识信息之间的映射关系。在本实施例中，处理模块200可以确定代谢物信息与信号调理芯片120之间的对应关系。而且，若建立了信号调理芯片120的身份标识信息与用户使用信息之间的对应关系，还能够获悉每一个代谢物信息对应的用户名称、尿不湿的穿戴时间等，从而便于追溯和数据分析。
在其中一个实施例中，所述数据处理单元220还用于生成并经所述第二线圈210发送数据获取指令。所述信号调理芯片120还用于经所述第一线圈130接收所述数据获取指令，并响应于所述数据获取指令，回传所述调理信号至所述数据处理单元220。可以理解的是，用户存在打开移动终端的APP并查询尿不湿当前的使用情况的需求，以确定是否需要更换尿不湿。因此，通过设置上述功能，可以获取即时的数据，从而提供准确的信息给用户，提升用户的使用体验。
图2为一实施例的传感器示意图之一，参考图2，在其中一个实施例中，所述传感单元110包括多个湿度传感器，多个湿度传感器均设置于传感层14的基材上。基材为柔性材料，以贴合用户的身体，且基材中埋设有导电线路，以传输各传感器的传感信号。多个湿度传感器分别设于代谢物扩散路径上的不同感测点，各所述湿度传感器分别用于感测所在感测点的湿度，并生成对应的湿度传感信号。其中，湿度传感器的数量可以为5个至10个，具体可以根据尿不湿的尺寸确定。其中，所述数据处理单元220还用于根据各所述湿度传感器传感到的湿度确定代谢物类型，所述代谢物类型包括液态代谢物和非液态代谢物。具体地，处理模块200可以根据各传感器的感测结果获取增长状态信息，并根据增长状态信息确定代谢物类型。增长状态信息用于表征各感测点的感测结果随时间的增长情况，例如可包括湿度增长速率、湿度增大后维持在预设湿度范围内的维持时间、湿度增大后维持在预设温度范围内的情况等。
一示例性地，处理模块200还用于若至少一个感测点的湿度增长速率大于速率阈值，则判定代谢物类型为液态代谢物。其中，速率阈值可根据液态代谢物在尿不湿的内芯层扩散时的湿度增长速率经验值进行确定。另一个示例性地，处理模块200还可用于若至少一个感测点的维持时间大于第一时间阈值，则判定代谢物类型为半固态代谢物；和/或若任一感测点的维持时间小于第二时间阈值，则判定为液态代谢物。其中，半固态代谢物指的带有代谢物中的液体的大便，例如可为稀便。可以理解的是，第一时间阈值可根据用户通常的持续排尿时间进行确定，例如可大于或等于用户的最长排尿时间。由于液态代谢物排出后会迅速被尿不湿的内芯层吸收，因此，其湿度只可能在持续排尿的情况下才得以保持。而由于半固态代谢物带有代谢物中的液体等液体，且其内的代谢物中的液体不会迅速被尿不湿的内芯层完全吸收，因此会使得感测点的湿度维持一段时间。若至少一个感测点的维持时间超过了第一时间阈值，即超过了用户正常排尿时间，则表明该感测点湿度的维持不是由排尿情况引起，而是由半固态代谢物引起的，因此此时可判定代谢物类型为半固态代谢物。图3为一实施例的半固态代谢物的湿度变化曲线示意图，参考图3，其中曲线l1为时间变化曲线，曲线l2为半固态代谢物的湿度值变化曲线。液态代谢物可例如为代谢物中的液体、血液等，第二时间阈值也可根据用户通常的持续排尿时间进行确定，例如可小于或等于最长排尿时间。可以理解的是，若至少一个感测点的维持时间小于第一时间阈值，即小于用户正常排尿时间，则可表明该感测点湿度的维持由排尿情况引起，因此此时可判定代谢物类型为液态代谢物。图4为一实施例的液态代谢物的湿度变化曲线示意图，参考图4，其中，曲线l3为时间变化曲线，曲线l4为液态代谢物的湿度值变化曲线。其中，第一时间阈值和第二时间阈值可相等。
图5为一实施例的传感器示意图之二，参考图5，在其中一个实施例中，所 述传感单元110包括至少一个温度传感器，温度传感器设于所述代谢物扩散路径上，所述温度传感器用于感测所在感测点的温度并生成对应的温度传感信号。在图5所示的实施例中，传感单元110包括三个温度传感器。其中，所述数据处理单元220还用于根据所述温度传感器传感到的温度确定代谢物类型，所述代谢物类型包括液态代谢物和非液态代谢物。
具体地，增长状态信息还可包括湿度增大后维持在预设温度范围内的维持时间，处理模块200还用于若至少一个湿度感测点的增长状态信息满足预设条件的同时，相邻的温度感测点的温度逐渐减小，则判定代谢物类型为半固态代谢物。可以理解的是，当代谢物为半固态代谢物时，由于其内的代谢物中的液体不会迅速被尿不湿的内芯层完全吸收，因此排泄后其湿度会维持在某一范围，此外其排出后温度会慢慢降低，而不会像持续排尿的情况会继续上升或维持在某一温度范围。因此，对于某一感测点，若该感测点的湿度增大后维持在预设湿度范围内，同时该感测点的温度逐渐减小，则可判定代谢物类型为半固态代谢物。
在其中一个实施例中，数据处理单元220还用于根据湿度确定目标数量，目标数量为湿度大于第二湿度阈值的感测点数量，并根据目标数量确定代谢量。其中，第二湿度阈值可为液态代谢物排泄至尿不湿的内芯层时尿不湿的内芯层的湿度。可以理解的是，若感测点的湿度大于第二湿度阈值，则说明该感测点有液态代谢物，通过合理设置各感测点的间距，使得接触到液态代谢物的感测点数量与代谢量一一对应，从而可根据感测点数量得到对应的代谢量。
图6为一实施例的湿度传感器的位置示意图，参考图6，各湿度传感器分别一一对应设置于湿度感测点A、B、C、D、E、F、G，并可基于各感测点划分出渗透区域L1-L4，其中渗透区域L1-L4的区域面积依次增大。当只有一个感测点接触到液态排泄物时，液态排泄物位于区域L1内，区域L1对应的代谢量可为20ml。 当有三个感测点接触到液态排泄物时，液态排泄物位于区域L2内，区域L2对应的代谢量可为40ml。以此类推，区域L2对应的代谢量可为40ml，区域L4对应的代谢量可为120ml。因此，在本实施例中，根据目标数量则可确定对应的代谢量，该方法简单，且能够有效测得代谢量。
在一些实施例中，为了确定代谢量，还可通过获取用户排泄过程中液态代谢物的排泄时间，结合单位时间排泄体积进一步确定代谢量。其中，排泄时间为用户开始排泄时刻和结束排泄时刻之间的时间间隔，开始排泄时刻可用用户小便排泄感测点的湿度的增长时刻来表征。由于液态排泄物排出后会被快速吸收，若停止排泄，感测点的湿度则会降低。因此，结束排泄时刻可用用户小便排泄感测点的湿度的衰减时刻来表征。其中，增长时刻感测点的湿度急剧增大，因此可根据目标感测点的湿度的增长率是否达到增长阈值来确定，衰减时刻感测点的湿度会急剧衰减，因此可根据衰减率是否达到衰减阈值来确定。其中，采集到的湿度可带有时间戳，从而可根据其判定增长时刻和衰减时刻。
在其中一个实施例中，温度传感器还用于至少传感用户大便排泄处的温度感测点的温度，并通过信号调理芯片120传输至处理模块200，至少一个传感器设置在温度感测点，以传感温度感测点的湿度，处理模块200还用于若温度感测点的温度发生升温变化，且相邻的湿度感测点的湿度小于第一湿度阈值，则判定代谢物类型为固态代谢物。可以理解的是，第一湿度阈值可小于或等于固态代谢物排泄至尿不湿的内芯层时，尿不湿的内芯层的最大湿度。若第一感测点的温度发生升温变化，则表明第一感测点有代谢物，同时若第一感测点的湿度小于第一湿度阈值，则表明其为固态代谢物，其中，固态代谢物可例如为干便。
在其中一个实施例中，温度传感器还用于感测尿不湿在穿戴状态下，对应用户各排泄处的尿不湿的内芯层上的多个感测点的温度，数据处理单元220还用 于根据温度确定温度扩散信息，并根据温度扩散信息判定代谢物类型。其中，温度扩散信息用于表征各感测点发生升温变化时的顺序。具体地，若温度扩散信息为由小便处感测点向大便处感测点相继发生升温变化，则确定代谢物类型为液态代谢物。若温度扩散信息为由大便处感测点向小便处感测点相继发生升温变化，则确定代谢物类型为非液态代谢物。可以理解的是，根据代谢物的排泄位置及扩散情况，可判定代谢物的具体类型，其中，液态代谢物可包括代谢物中的液体或血液，非液态代谢物可包括固态代谢物，例如干便，还可包括半固态代谢物，例如稀便。
图7为一实施例的传感器示意图之三，参考图7，在其中一个实施例中，所述传感单元110还包括液相代谢物传感器。液相代谢物传感器设于所述尿不湿的生化反应区，用于感测由所述尿不湿的液体虹吸通道流入所述生化反应区的液体，并生成对应的液相生化传感信号。其中，所述数据处理单元220还用于获取与所述液相生化传感信号对应的液相生化信息。
具体地，所述液相代谢传感器设计有单独的液体虹吸通道和生化反应区，用于保证多种代谢物的检测，使得检测结果不受液滴流道和相互之间信号的影响。其中，可以检测的物质包括但不限于pH值，葡萄糖，多巴胺，尿酸，抗坏血酸，半乳糖，酮体，白细胞，蛋白质，隐血，K+离子，Na+离子，碘离子，钙离子，铁离子，锌离子，亚硝酸盐等。具体地，图8为一实施例的液相代谢传感器处的剖视示意图，参考图8，液相传感器的敏感材料层设于基材上的各感测点处，用于代谢物质发生特定反应产生电信号。相邻的两块敏感材料层之间设置有隔层，用于间隔相邻的敏感材料层并构建虹吸通道，以锁存代谢物中的液体。隔层上设有亲水膜层，亲水膜层用于吸收代谢物中的液体，从而将液体导入虹吸通道。在图8所示的实施例中，液相成分分析的虹吸通道入口通过在亲水膜层打孔来实 现。可以理解的是，液相成分分析需要建立一个稳定的反应区，从而保证在检测时间内，反应区内的代谢物中的液体是充足的，否则代谢物中的液体可能会被尿不湿的内芯层吸走，不能满足生化检测的需求。上述结构提供了一个稳定的反应区，代谢物中的液体通过虹吸作用进入到反应区，被反应区的敏感材料层检测到，从而实现液相分析。
继续参考图7，在其中一个实施例中，所述传感单元110包括气相代谢物传感器和包覆所述气相代谢物传感器的气体锁存结构，所述气体锁存结构用于锁存所述代谢物中的气体，所述气相代谢物传感器用于感测锁存的气体并生成对应的气相生化传感信号。其中，所述数据处理单元220还用于获取与所述气相生化传感信号对应的气相生化信息。与虹吸通道类似地，气体锁存结构能够建立一个稳定的反应区，从而保证在检测时间内，反应区内的气体是相对稳定的，否则代谢物中的气体挥发，不能满足生化检测的需求。上述结构提供了一个稳定的反应区，代谢物中的气体由气体锁存结构固定在反应区，被反应区的敏感材料层检测到，从而实现气相分析；气相分析物质包括(但不限于)氨气、硫化氢、氢气、粪臭素等。
图9为一实施例的处理模块200的结构示意图，参考图9，在其中一个实施例中，所述处理模块200还包括操作单元230、指示单元240和电源管理单元250中的至少一个。
具体地，所述操作单元230与所述数据处理单元220连接，用于接收用户输入的激活操作并对应的生成激活信号，传输所述激活信号至所述数据处理单元220。其中，激活信号可以为当处理模块200放入容置袋时，处理模块200能够自动检测到传感模块100，并发送激活信号至传感模块100，以建立与传感模块100之间通讯，从而获取传感模块100的ID信息、生产制造时间、配置信息、 是否已经使用过等信息。所述指示单元240与所述数据处理单元220连接，用于接收所述数据处理单元220输出的指示信号，并根据所述指示信号携带的状态信息对用户进行指示，所述指示信号携带的状态信息包括所述代谢物状态信息、传感模块100状态信息和处理单元状态信息中的至少一个。其中，代谢物状态信息是指排泄次数、使用时长、检测指标是否超出设定值等，传感模块100状态信息是指传感器的开关状态、线圈的电磁耦合状态等，处理单元状态信息是指处理模块200的工作是否正常，处理模块200的电量是否正常等。可以理解的是，为避免尿不湿液态代谢物堆积过多，从而影响尿不湿后续的吸收作用，更影响用户健康，指示单元240可当液态代谢物的代谢量超过设置的警示值时，输出警示信息以提醒用户进行更换。其中，警示信息可为声音信号。所述电源管理单元250与所述数据处理单元220连接，用于对所述数据处理单元220进行供电。
本申请实施例还提供了一种尿不湿，图10为一实施例的尿不湿的剖视示意图之一，参考图10，尿不湿包括表层11、底层12、至少一个内芯层13和传感层14，图中示出了一个内芯层13。其中，表层11靠近用户皮肤，底层12远离用户皮肤。内芯层13设于所述表层11与所述底层12之间如上述的代谢物检测装置，内芯层13也可以称为吸收层，用于吸收代谢物。所述传感层14设于所述表层11与所述底层12之间，且所述传感层14与所述底层12之间设有至少一个所述内芯层13。例如，若尿不湿包括层叠依次设置的三个内芯层13，则可以将传感层14设置在第一内芯层13与表层11之间，也可以将传感层14设置在第一内芯层13与第二内芯层13之间，也可以将传感层14设置在第二内芯层13与第三内芯层13之间，还可以将传感层14设置在第三内芯层13与底层12之间，本实施例不做限定。所述代谢物检测装置中的传感模块100设于所述传 感层14，即，代谢物检测装置中的传感单元110、信号调理芯片120和第一线圈130均设于所述传感层14。而且，所述代谢物检测装置中的处理模块200设于所述底层12的外侧，即，代谢物检测装置中的第二线圈210和数据处理单元220均设于底层12的外侧。在本实施例中，将处理模块200设置在远离用户皮肤的一侧，可以用于随时更换处理模块200，也可以方式处理模块200中流入代谢物，影响处理模块200的运行。
继续参考图10，在其中一个实施例中，所述代谢物处理装置中的第一线圈130与第二线圈210之间的耦合路径上设置有部分所述内芯层13。其中，所述处理单元还用于获取所述耦合路径上的电磁耦合效率，并根据所述电磁耦合效率获取所述内芯层13的代谢物吸收量。可以理解的是，内芯层13的吸湿状态会影响电磁耦合效率，因此，通过设计的算法也可以用于代谢物量判断，以及是否需要更换尿不湿。
图11为一实施例的尿不湿的剖视示意图之二，参考图11，在其中一个实施例中，所述代谢物处理装置中的第一线圈130与第二线圈210之间的耦合路径上不设置所述内芯层13。可以理解的是，若耦合路径上不设置内芯层13，可以避免内芯层13的吸湿状态对影响电磁耦合效率的影响，从而可以有效避免长时间未更换尿不湿时，第一线圈130与第二线圈210的连接不稳定甚至断开的情况。因此，在本实施例中，通过设置上述结构，可以有效确保通信的可靠性。
在其中一个实施例中，尿不湿还包括容置袋。容置袋连接于所述底层12的外侧，用于容置所述处理模块200，所述容置袋设有开口，且所述开口处设有开关结构，所述开关结构用于在打开时暴露所述开口，以经所述开口放入或取出所述处理模块200，所述开关结构还用于在关闭时封闭所述开口，以防止所述处理模块200在工作过程中脱出。具体地，当用户对尿不湿进行更换时，可以将处理 模块200安装至新的尿不湿的容置袋中，从而降低用户的使用成本。而且，相较于有线连接方式，本申请实施例的尿不湿在进行处理模块200的拆装时，无需进行连接线的对位等操作，从而可以提高拆装的便捷性。此外，还可以通过对处理模块200的软件功能升级，使尿不湿能够支持更加丰富的检测和分析功能，而且可以理解的是，基于无线连接的方式，在进行软件功能升级后，无需对处理模块200的pin脚、连接线等硬件结构进行改进，从而可以在不过度增大成本的前提下，有效提高处理模块200的功能扩展性。在本实施例中，通过设置容置袋，可以确保处理模块200的位置不发生过大的移动，从而确保通信过程的可靠性。而且，通过为容置袋设置带有开关结构的开口，可以避免处理模块200从容置袋中自然脱出，从而进一步提高可靠性。
在其中一个实施例中，所述容置袋设于所述传感模块100中的第一线圈130的对应位置，以使所述第二线圈210与所述第一线圈130之间的耦合路径最短。通过上述设置方式，可以使两个线圈之间的传输效率最高，从而提高通信过程的通信速率。
本申请实施例还提供了一种护理系统，图12为一实施例的护理系统的结构示意图，参考图12，护理系统包括移动终端和上述的尿不湿。移动终端包括第一无线传输单元，所述尿不湿的处理模块200还包括第二无线传输单元260(参考图9)，所述第二无线传输单元260与数据处理单元220连接，用于发送所述代谢物信息至所述移动终端的第一无线传输单元，并接收来自所述第一无线传输单元的控制指令。尿不湿中的处理模块200作为主机，通过无线传输单元将监测数据发送至移动终端的APP。移动终端的APP能够获取处理模块200发送的数据，将数据处理后显示在APP的UI界面上，以实现用户的查看、反馈等功能。
继续参考图12，在其中一个实施例中，护理系统还包括云端服务器，所述 移动终端还用于发送所述代谢物信息至所述云端服务器，所述云端服务器用于对接收到的所述代谢物信息进行存储和分析。移动终端的APP还能够将获取到的数据转发至云端，从而实现数据的云端存储，以及更丰富的分析和应用决策的功能，从而提高使用过程的灵活性。

以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
