请一并参阅图4，图4为本申请第一实施例提供的除颤仪中检测器的电路结构示意图。检测器300包括信号产生模块310、检测模块320及判断模块330。信号产生模块310用于产生测试信号，所述检测模块320用于检测测试信号经由第一电极片210及第二电极片220后产生的检测信号，判断模块330根据检测信号判断第一电极片210及第二电极片220与主机100之间的连接是否正常，以及判断第一电极片210及第二电极片220是否正常。
具体地，当检测模块320接收到检测信号时，判断模块330判定第一电极片210及第二电极片220与主机100之间的连接正常。当检测模块300接收不到检测信号时，判断模块330判定第一电极片210及第二电极片220与主机100之间的连接异常。
进一步地，判断模块330根据检测模块320接收到的检测信号中电阻值的大小来判断第一电极片210及第二电极片220是否正常。举例而言，当第一电极片210及第二电极片220中的导电胶性能不好时(比如，导电胶干了)，则得到的检测信号中电阻值超过预设电阻值；当第一电极片210及第二电极片220中的导电胶性能良好时，则得到的检测信号中电阻值小于或等于预设电阻值。
本实施例中检测模块320可以根据能否接收到检测信号来判断第一电极片210及第二电极片220与主机100之间的连接是否正常，且同时可以根据检测信号中电阻值的大小来判断第一电极片210及第二电极片220是否正常，从而达到了一次测量进行多个判定的技术效果。
进一步地，信号产生模块310包括第一端311及第二端312。第一端311与第一电极片210电连接，第二端312与第二电极片220电连接，测试信号经由第一端311及第二端312输出至第一电极片210及第二电极片220。
进一步地，检测信号为模拟信号，检测器300包括采样模块340，采样模块340用于将检测信号进行采样，判断模块330根据进行采样后的检测信号判断第一电极片210及第二电极片220与主机100之间的连接是否正常，以及判断第一电极片210及第二电极片220是否正常，其中，采样后的检测信号为数字信号。测试信号为模拟信号，采样模块340将测试信号进行采样以得到数字信号，以减小判断模块330进行判断时处理的数据量。
进一步地，检测器300还包括放大模块350，放大模块350用于将检测信号进行放大后输出至采样模块340。此时，采样模块340用于将放大后的检测信号进行采样。放大模块350将检测信号放大后可以提高判断结果的精确性。
请参阅图5，图5为本申请第一实施例提供的除颤仪的等效电路示意。第一电极片210与主机100之间的接触电阻等效为第一电阻R1，第二电极片220与主机100之间的接触电阻等效为第二电阻R2，第一电极片210与第二电极片220之间等效为电容C，电容一端连接第一电阻R1，电容C的另一端连接第二电阻R2，即，当第一电极片210与及第二电极片220均与主机100连接良好时，信号产生模块310、第一电阻R1、第二电阻R2及电容C形成了一个回路。当信号产生模块310产生的一定频率和幅度的测试信号经由第一电极片210及第二电极片220之后，检测模块320检测电容上的信号以得到检测信号。判断模块330根据检测信号判断第一电极片210与主机100之间的连接是否正常，判断第二电极片220与主机100之间的连接是否正常，以及判断第一电极片210与第二电极片220是否正常。具体判断过程详细描述如下。
当第一电极片210正常且第一电极片210与主机100之间连接正常时，第一电阻R1的阻值很小；当第二电极正常且第二电极片220与主机100之间连接正常时，第二电阻R2的阻值很小。当第一电极片210正常且第一电极片210与主机100之间连接正常时第一电阻R1的阻值通常低于0.2欧；当第二电极正常且第二电极片220与主机100之间连接正常时，第二电阻R2的阻值通常通常低于0.2欧。而第一电极片210及第二电片之间的等效电容通常为100pF～200pF之间。当第一电极片210正常且第一电极片210与主机100之间连接正常，且当第二电极片220正常且第二电极片220与主机100之间连接正常时，当信号产生模块310产生的一定频率和幅度的测试信号经由第一电极片210及第二电极片220之后，检测模块320可以根据测试信号得到对应的检测信号。
当前述回路出现异常时，比如，第一电极片210未连接到主机100上，或者，第二电极片220未连接到主机100上，此时，当测试信加载到第一电极片210及第二电极片220上时，检测模块320几乎采集不到检测信号。同样地，当第一电极片210及第二电极片220不存在相对的面积时，或者，当第一电极片210中的导电胶黏性不好，或者第一电极片210中的导电胶干，或者第二电极片220中的导电胶黏性不好，或者第二电极片220中的导电胶干，则，第一电极片210与第二电极片220之间无法形成电容。此时，则无法形成第一电阻R1、第二电阻R2及电容的分压网络，则，根据检测信号得到的阻抗值大于预设阻抗值。
进一步地，测试信号包括第一测试子信号及第二测试子信号。检测信号包括第一检测子信号及第二检测子信号，当第一测试子信号信号加载在第一电极片210及第二电极片220上时对应的检测信号为第一检测子信号，当第二测试子信号加载到第一电极片210及第二电极片220上时对应的检测信号为第二检测子信号，判断模块330根据第一检测子信号以及第二检测子信号之间的差异判断第一电极片210及第二电极片220与主机100之间的连接是否正常，以及判断第一电极片210及第二电极片220是否正常。本实施例中通过比较第一检测子信号及第二检测子信号之间的差异可以提高判断结果的精确性。
具体地，信号产生模块310产生第一测试子信号及第二测试子信号。当第一测试子信号加载在第一电极片210及第二电极片220上时，检测模块320得到的检测信号命名为第 一检测子信号；当第二测试子信号加载在第一电极片210及第二电极片220上时，检测模块320得到的检测信号命名为第二检测子信号。本实施例中，通过两次检测结果，可以提高判断结果的精确性。
进一步地，检测器300还包括时序控制模块360。时序控制模块360控制第一测试子信号先于第二测试子信号加载在第一电极片210及第二电极片220上，第二测试子信号的频率与第一测试子信号的频率不同，或者，第二测试子信号的幅值大于第一测试子信号的幅值。在本实施例中，时序控制模块360与信号产生模块310电连接，以控制信号产生模块310产生的第一测试子信号及第二测试子信号加载到第一电极片210及第二电极片220上的时序。
由于电容的频率特性为Xc＝1/(2πfc)，其中，Xc为电容的等效阻抗，fc为检测信号的频率，因此，对于不同频率的测试信号而言，电容对应的等效阻抗不一样。当第一电极片210及第二电极片220之间由于包装等原因而不能正常面对时，第一电极片210与第二电极片220之间的耦合性比较差，则，对于当检测信号的频率为低频时，不能较为精确的判断第一电极片210及第二电极片220与主机100之间的连接是否正常，且不能较为精确的判断第一电极片210及第二电极片220是否正常。因此，判断模块330根据比较不同频率的第一测试子信号及第二测试子信号对应的第一检测子信号及第二检测子信号之间的差异，可以提高判断结果的精确性。进一步地，第二测试子信号的幅度大于第一测试子信号的幅值，有利于提升信噪比，进一步提高判断结果的精确性。
进一步地，请参阅图6，图6为本申请第二实施例提供的除颤仪的电路结构示意图。本实施方式提供的除颤仪1与本申请第一实施方式提供的除颤仪1的结构基本相同，不同之处在于，在本实施方式中检测器300还包括第一测试电阻370。第一测试电阻370一端电连接第一电极片210，第一测试电阻370的另一端电连接第二电极片220。检测模块320一端电连接第一测试电阻370与第一电极片210之间的节点，检测模块320的另一端电连接在第一测试电阻370与第二电极片220之间的节点。
当由于种种原因第一电极片210及第二电极片220之间不能形成电容时，本实施例中通过增加第一测试电阻370电连接在第一电极片210及第二电极片220之间，以提高形成测试所需要的回路的确定性。检测模块320将检测到的电阻值与第一测试电阻370的电阻值进行比较，以判断第一电极片210与主机100之间连接是否正常且可以判断第二电极片220与主机100之间连接是否连接正常。具体地，当第一电极片210与主机100之间连接正常且第二电极片220与主机100之间连接正常时，检测信号所表征的电阻值与第一测试电阻370的电阻值的差值在预设范围内；当第一电极片210与主机100之间连接不正常或第二电极片220与主机100之间连接不正常或第一电极片210及第二电极片220与主机100之间连接均不正常时，检测信号所表征的电阻值与第一测试电阻370的电阻值的差值超过预设范围。因此，本实施例可以通过检测第一测试电阻370是否连接正常可以判断出第一电极片210与主机100之间连接是否正常，以及第二电极片220与主机100之间连接是否正常。
进一步地，当除颤仪1正常使用的时候，使用者将第一电极片210及第二电极片220从包装袋中取出，且将第一电极片210及第二电极片220粘结到目标对象身上不同部位时，可将断开第一测试电阻370与第一电极片210片之间的连接，或者断开第一测试电阻370与第二电极片220之间的连接，或者断开第一测试电阻370与第一电极片210及第二电极片220之间的连接，从而不影响除颤仪1的正常使用。
进一步地，请一并参阅图7及图8，图7为本申请第三实施例提供的除颤仪中第一电极片及第二电极片未插接到主机上的结构示意图；图8为本申请第三实施例提供的除颤仪中的第一电极片及第二电极片插接到主机上的结构示意图。本实施例提供的除颤仪1与本 申请第一实施例提供的除颤仪1的结构基本相同，第一电极片210与第二电极片220通过接头插接到主机100上的插孔中。不同之处在于，在本实施例中，检测器300还包括第二测试电阻380。第二测试电阻380一端电连接第一电极片210的接头，第二测试电阻380的另一端电连接第二电极片220的插头，检测模块320电连接主机100的插孔，判断模块330根据检测模块320检测到的电阻值以及第二测试电阻380的电阻值判断第一电极片210及第二电极片220与主机100之间的连接是否正常。

可以理解地，在实施例中，检测器300还可以包括采样模块及放大模块，采样模块及放大模块与检测器300中其他模块的连接关系以及采集模块及放大模块的作用请参阅图4及其相关描述，在此不再赘述。

进一步地，集成芯片390存储有第一电极片210及第二电极片220的出厂日期及有效期，当检测模块320读从集成芯片390中读取到第一电极片210及第二电极片220的出厂日期及有效期时，判断模块330还根据当前日期、出厂日期及有效期判断第一电极片210及第二电极片220是否过期。

本实施例中检测模块320可以根据能否接收到检测信号来判断第一电极片210及第二电极片220与主机100之间的连接是否正常，且同时可以根据检测信号中电阻值的大小来判断第一电极片210及第二电极片220是否正常，从而达到了一次测量进行多个判定的技术效果。
