除颤方法、自动体外除颤仪及计算机可读取介质 技术领域
本申请涉及医疗器械技术领域，尤其涉及一种除颤方法、自动体外除颤仪及计算机可读取介质。
背景技术
心脏骤停等心脏疾病是导致人类死亡的主要原因之一。心脏骤停病人早期约有85～90％是室颤，治疗室颤主要的方式是采用自动体外除颤仪(Automated External Defibrillator，AED)对病人进行电击除颤。据研究，除颤每推迟一分钟，则病人的存活率降低7％～10％。因此，如何在病人发病时进行及时除颤对挽救病人的生命至关重要。然而，传统的自动体外除颤仪检测到病人满足电击除颤条件到对病人进行电击除颤所用的时间较长。

在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本申请的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
为了使本申请实施例提供的技术方案更加清楚，下面结合附图对上述方案进行详细描述。
请一并参阅图1及图2，图1为本申请提供的除颤方法所应用的自动体外除颤仪的电路结构示意图；图2为本申请一实施例提供的除颤方法的流程示意图。自动体外除颤仪1包括一对电极片10、传感器20、充电电路30、放电电路40、电源50。自动体外除颤仪中各个元器件的作用和原理结合本申请的除颤方法进行介绍。
本申请实施例提供的除颤方法包括但不仅限于包括步骤S110、S120、S130、S140、S150及S10，各个步骤详细介绍如下。
S110，获取开机指令并根据开机指令完成初始化。
S120，判断自动体外除颤仪1的电极片10是否粘结到目标对象上。
具体地，请一并参阅图3，图3为图2所示的除颤方法中S120所包括的流程示意图。S120包括S121、S122、S123及S124，S121、S122、S123及S124详细介绍如下。
S121，获取两个电极片10之间的电阻值。
S122，判断两个电极片10之间的电阻值是否位于预设电阻值范围内。
S123，当两个电极片10之间的电阻值位于预设电阻值范围内时，判定电极片10粘结到目标对象上。
S124，当两个电极片10之间的电阻值大于预设电阻值范围中的最大值时，判定电极片10未粘结到目标对象上。
S130，当电极片10粘结到目标对象上后，感测目标对象的心脏活动对应的第一心电图(Electrocardiograph，ECG)信号。具体地，当电极片10粘结到目标对象上时，传感器20感测目标对象的心脏活动，并得到目标对象的心脏活动对应的心电图信号，以得到第一ECG信号。
通常而言，当两个电极片10之间的电阻值位于所述预设电阻值范围内时，即，两个电极片10之间的电阻值大于或等于所述预设电阻值范围中的最小值且小于或等于所述预设电阻值范围中的最小值，则判定电极10粘结到目标对象身上且粘结位置正常；当两个电极片10之间的电阻值大于所述预设电阻值范围中的最大值时，判定电极片10与未粘结到目标对象上；当两个电极片10之间的电阻值小于所述预设电阻值范围中的最小值时，则判断两个电极片10短路或两个电极片10粘结到目标对象上的粘结位置太近。通常而言，所述预设电阻值范围的最大值比人体电阻的上限值的大预设裕量。在本实施例中，所述预设电阻值范围为大于10欧且小于600欧，即，所述预设电阻值范围的最大值为600欧，所述预设电阻值范围的最小值为10欧。
具体的，请一并参阅图4，图4为图2所示的除颤方法中S130所包括的流程示意图。S130包括S131、S132及S133，S131、S132及S133详细介绍如下。
S131，感测电极片10粘结到目标对象上时的第一信号。
S132，判断第一信号中是否存在表征起搏器的第二信号。
S133，当第一信号中存在表征起搏器的第二信号时，将第一信号中减去第二信号得到第一ECG信号，当第一信号中不存在表征起搏器的第二信号时，则将第一信号设定为第一ECG信号。
当目标对象佩戴有起搏器时，则起搏器会对判断目标对象是否满足电击条件造成干扰，因此，本实施例中可以去除起搏器的干扰，以避免误判断。
S140，对第一ECG信号进行分析以判断目标对象是否满足电击条件。
S150，当目标对象满足电击条件且收到电击指令时，对目标对象进行放电治疗。
在一实施例中，图5为图2所示的除颤方法中S150所包括的流程示意图。“S150对 目标对象进行放电治疗”之前，所述除颤方法还包括S151及S153，S151及S153详细介绍如下。
S151，检测自动体外除颤仪1的电极片10是否脱落。
S153，当自动体外除颤仪1的电极片10脱落时，终止对目标对象进行放电治疗且保存充电电路30中的电能。
在本实施例中，在自动体外除颤仪1的电极片10脱落时，终止对目标对象进行放电治疗，以避免自动体外除颤仪1的放电电路40通过电极片10释放的除颤信号递至对目标对象进行救护的救护人，以免除颤能量对救护人造成伤害。进一步地，保存充电电路30中的电能可以减小为充电电路30进行充电的电源50的能量消耗。
其中，在所述“S140，对第一ECG信号进行分析以判断目标对象是否满足电击条件”之前，除颤方法还包括S10，启动对自动体外除颤仪1中的充电电路30进行充电。为了方便示意，在图1中，将S10标示在S150之前，且位于S140之后，可以理解地，S10只要在S150之前即可，并不仅仅限于在S150之前且位于S140之后。
除颤方法还包括：当目标对象满足电击条件但是在预设时间段内未收到电击指令时，禁止对目标对象进行放电且保存充电电路30中的电量。
在本实施例中，当在预设时间段内未收到电击指令时，禁止对目标对象进行放电且保存充电电路30中的电量可以节约为充电电路30进行充电的电源50的能量消耗。
进一步地，“S10，启动对自动体外除颤仪1中的充电电路30进行充电”之后，所述除颤方法还包括：对自动体外除颤仪1中的充电电路30进行充电时充电至第一预设电量，其中，第一预设电量大于或等于对目标对象进行放电治疗所需要的电量。
本申请中的除颤方法应用于自动体外除颤仪1中，自动体外除颤仪1包括电极片10及传感器20。通常，电极片10的数量为两个，自动体外除颤仪1在使用的时候，两个电极片10被粘结到目标对象上。举例而言，电极片10被粘结到但不仅限于粘结到目标对象的胸口。当电极片10粘结到目标对象上时，传感器20可通过电极片10感测目标对象的心脏活动的ECG信号，以得到第一ECG信号。在本实施例中，目标对象可以为成人也可以为儿童。当获得第一ECG信号时，对第一ECG信号进行分析以判断目标对象是否满足电击条件。举例而言，当根据第一ECG信号判断目标对象的心律包括心室颤动、室性心动过速及心室扑动中的至少一种时，则可判定目标对象满足电击条件。当根据第一ECG信号判断目标对象的心律为心动过缓、电机械分离、室性自主心律和正常的心律中的任意一种时， 则可判定目标对象不满足电击条件。
当电极片10粘结到目标对象上时，当目标对象满足电击条件时且收到电击指令时，对目标对象进行放电治疗。在一实施例中，当目标对象满足电击条件时，自动触发电击指令。在另一实施例中，自动体外除颤仪1包括放电按钮，当放电按钮被按压时，触发电击指令。具体地，当目标对象满足电击条件时，自动体外除颤仪1的报警单元发出提示信息，提示信息用于提示目标对象可电击，操作者可根据提示信息按压放电按钮，以触发电击指令。
请参阅图1，自动体外除颤仪1还包括充电电路30及放电电路40。充电电路30用于接收并存储电能，当目标对象满足电击条件的时候，充电电路30中存储的能量经过放电电路40加载到电极片10上，并传递至目标对象。在一实施例中，充电电路30及放电电路40也可以集成为一个充放电模块，充放电模块可以接收充电信号，并存储能量，且又可将存储的能量释放。在一实施例中，自动体外除颤仪1包括电源50，电源50用于为充电电路30提供电能。电源50可以为一次性电池，也可以为充电电池。
当电击指令被触发之后，自动体外除颤仪1中的放电电路40通过电极片10将除颤信号递至目标对象，除颤信号用于帮助将目标对象的心律恢复正常。通常情况下，除颤信号为高压脉冲信号。
当自动体外除颤仪1对目标对象进行放电治疗时，需要一定的电量，则将充电电路30充至满足对目标对象进行放电治疗所需要的电量的时候，所需要的充电时间一定，那么，本申请实施例中的除颤方法在“S140，对第一ECG信号进行分析以判断目标对象是否满足电击条件”之前就对自动体外除颤仪1的充电电路30进行充电，可以节约在判断出目标对象满足电击条件且收到电击指令之后对充电电路30的充电时间，从而可以在目标对象满足电击条件且收到电击指令之后快速对目标对象进行放电治疗，节约了自动体外除颤仪1从检测到目标对象满足电击除颤条件到对目标对象进行电击除颤所用的时间，有利于挽救目标对象的生命。
进一步地，本申请的除颤方法在“对第一ECG信号进行分析以判断目标对象是否满足电击条件”之前对自动体外除颤仪1中的充电电路30进行充电时充电至第一预设电量，其中，第一预设电量大于或等于对目标对象进行放电治疗所需要的电量。从而使得当目标对象满足电击条件且收到电击指令时就有足够的电量对目标对象进行治疗，进一步缩短了除颤仪从开机到对目标对象进行放电所用到的时间。
更进一步地，当第一预设电量大于对目标对象进行放电治疗所需要的电量时，在所述 “S150，当目标对象满足电击条件且收到电击指令时，对目标对象进行放电治疗”之后，除颤方法还包括S160。
S160，保存充电电路30中剩余的电量。
进一步地，在S160之后，所述除颤方法还包括S170。
S170，在充电电路30保存剩余电量的基础上对充电电路30进行充电。优选地，在S170中，在充电电路30保存剩余电量的基础上对充电电路30进行充电至第二预设电量。其中，第二预设电量大于或等于对目标对象进行放电治疗所需要的电量。
在本实施例中，当第一预设电量大于对目标对象进行放电治疗所需要的电量时，且对目标对象进行放电治疗之后保存充电电路30中剩余的电量，在剩余电量的基础上对充电电路30进行充电，可以缩短对充电电路30充电至第二预设电量的时间，且可以节约为充电电路30进行充电的电源50的能量消耗。
进一步地，除颤方法在S170之后还包括S180、S182及S184，S180、S182及S184详细介绍如下。
S180，感测目标对象的心脏活动对应的第二ECG信号。
S182，对第二ECG信号进行分析以判断目标对象是否满足电击条件。
S184，当目标对象满足电击条件时，对目标对象再次进行放电治疗。
经过S150中对目标对象进行放电治疗，继续感测目标对象的心脏活动对应的第二ECG信号，当目标对象满足电击条件时，再次对目标对象进行放电治疗。
进一步地，在其他实施例中，在感测目标对象的心脏活动对应的第二ECG信号的同时，在充电电路30保存剩余电量的基础上对充电电路30进行充电。即，除颤方法在S160之后包括：S172、S174、S176。
S172，感测目标对象的心脏活动对应的第二ECG信号的同时，在充电电路30保存剩余电量的基础上对充电电路30进行充电。
S174，对第二ECG信号进行分析以判断目标对象是否满足电击条件。
S176，当目标对象满足电击条件时，且当充电电路30中的电量大于或等于对目标对象进行放电治疗所需要的电量时，对目标对象再次进行放电治疗。
本实施例中的除颤方法在感测目标对象的心脏活动对应的第二ECG信号的同时，在充电电路30保存剩余的电量的基础上开始对充电电路30进行充电，从而缩短了对目标对象再次进行放电治疗所需要的时间。
进一步地，除颤方法还包括：S152，当目标对象满足电击条件但是在预设时间段内未收到电击指令时，禁止对目标对象进行放电且保存充电电路30中的电量。
本实施例中，当目标对象满足电击条件，但是在预设时间段内未收到电击指令时，则不对目标对象进行放电且保存充电电路30中的电量，即，充电电路30不进行能量泄放，可以节约为充电电路30进行充电的电源50的能量消耗。预设时间段从判断出目标对象满足电击条件开始计算。预设时间段可以为但不仅限于从判断出目标对象满足电击条件开始计算的30秒内。
请参阅图6，图6本本申请另一实施例提供的除颤方法的流程示意图。除颤方法包括但不仅限于包括S210、S220、S230、S240及S250，各个步骤详细介绍如下。本实施例提供的除颤方法与前面实施例提供的除颤方法基本相同，不同之处在于，在本实施例中，在获取开机指令的同时或之后即对自动体外除颤仪1的充电电路30进行充电。为了方便示意，将本实施例提供的除颤方法介绍如下。虽然在本实施例以及相关附图中以除颤方法括S210、S220、S230、S240及S250为例进行介绍，可以理解地，对于本实施例与前面实施例中相同的步骤，可以参阅前面的描述，在此不再赘述。
S210，获取开机指令并根据开机指令完成初始化，且在获取开机指令的同时或之后即对自动体外除颤仪1的充电电路30进行充电。
S220，判断自动体外除颤仪1的电极片10是否粘结到目标对象上。
S230，当电极片10粘结到目标对象上时感测目标对象的心脏活动对应的第一心电图(Electrocardiograph，ECG)信号。
S240，对第一ECG信号进行分析以判断目标对象是否满足电击条件。
S250，当目标对象满足电击条件且收到电击指令时，对目标对象进行放电治疗。
本申请一实施例中在获取开机指令的同时对自动体外除颤仪1的充电电路30进行充电，可以进一步节约自动体外除颤仪1从检测到目标对象满足电击除颤条件到对目标对象进行电击除颤所用的时间，有利于挽救目标对象的生命。
具体地，从获取开机指令到对第一ECG信号进行分析至判断目标对象满足电击条件所需要的时间为第一时间，在自动体外除颤仪1的充电电路30中的电能从零充电至满足对目标对象进行放电治疗所需要的电量时所需要的时间为第二时间。从获取开机指令到判断出目标对象满足电击条件再对充电电路30进行充电至满足对目标对象进行放电治疗所需要的电量时花费的时间为第三时间，第三时间等于第一时间加上第二时间。通常情况下，第 二时间小于第一时间，举例而言，第二时间为8秒，第一时间为10秒，第三时间为18秒。本实施例在获取开机指令的同时对自动体外除颤仪1的充电电路30进行充电相较于判断出目标对象满足电击条件之后再对充电电路30进行充电可以节约时间，有利于挽救目标对象的生命。
更进一步地，在一实施例中，在获取开机指令的同时或之后即对自动体外除颤仪1的充电电路30进行充电，直至判断判断出目标对象满足电击条件时停止充电，即，在第一时间内均对充电电路30进行充电，由于第一时间大于第二时间，因此，对于同样的充电电压而言，在获取开机指令的同时对自动体外除颤仪1的充电电路30进行充电可以使得充电电路30存储更多的电量，当对目标对象进行放电治疗后仍然会剩余部分电量，当在剩余电量的基础上继续对充电电路30进行充电以再次满足对目标对象进行放电治疗所需要的电能时，可以节约充电时间。
更进一步地，在一实施例中，在第一时间内对自动体外除颤仪1的充电电路30进行充电的充电电压小于第二时间内对自动体外除颤仪1的充电电路30进行充电的电压，以使得在第一时间内对自动体外除颤仪1的充电电路30冲的电能刚好等于对目标对象进行放电治疗所需要的电能。在本实施例中，可以降低对自动体外除颤仪1中的电源50以及充电电路30及放电电路40中的元器件的等级要求，有利于增加自动体外除颤仪1的可靠性。举例而言，当电源50为12V的一次性电池时，对于电压为12V的一次性电池而言，当充电时间为第二时间(8秒)，需要电池的带载能力为3.25A；当充电时间为第一时间(10秒)时，需要电池的带载能力为2.6A，因此，本实施例中对自动体外除颤仪1中的电源50以及充电电路30及放电电路40中的元器件要求更低，在自动体外除颤仪1中的电源50以及充电电路30及放电电路40中的元器件水平相同的情况下，本实施例中可以提高除颤方法所应用的自动体外除颤仪1的稳定性及可靠性。
本申请还提供了一种自动体外除颤仪1，下面结合前面介绍的除颤方法对本申请的自动体外除颤仪1进行介绍。请一并参阅图7，图7为本申请一实施例提供的自动体外除颤仪的模块结构示意图。自动体外除颤仪1包括指令获取模块810、判断模块820、感测模块830、充电模块840、放电模块850及控制模块860。指令获取模块810、判断模块820、感测模块830、充电模块840、放电模块850及控制模块860可以以软件程序或者固件(firmware)的形式固化在自动体外除颤仪1中，也可以存储在自动体外除颤仪1的存储器70中，并由自动体外除颤仪1的处理器60控制各个功能模块的执行，各个模块的详细工 作原理介绍如下。

具体地，请参阅图8，图8为图7所示的自动体外除颤仪中的感测模块的电路示意图。感测模块830还包括感测子模块831及设置子模块831。感测子模块831，感测电极片10粘结到目标对象上时的第一信号。判断模块820，判断第一信号中是否存在表征起搏器的第二信号。当第一信号中存在表征起搏器的第二信号时，设置子模块831将第一信号中减去第二信号得到第一ECG信号，当第一信号中不存在表征起搏器的第二信号时，则将第一信号设定为第一ECG信号。
判断模块820还对第一ECG信号进行分析以判断目标对象是否满足电击条件。
放电模块850，当目标对象满足电击条件且收到电击指令时，通过自动体外除颤仪1的放电电路40对目标对象进行放电治疗。

进一步地，控制模块860在判断模块820对第一ECG信号进行分析以判断目标对象是否满足电击条件之前控制充电模块840启动对自动体外除颤仪1中的充电电路30进行充电时充电至第一预设电量，其中，第一预设电量大于或等于对目标对象进行放电治疗所需要的电量。
进一步地，控制模块860在指令获取模块810取开机指令时或之后，控制充电模块840启动对自动体外除颤仪1的充电电路30进行充电。
更进一步地，请参阅图9，图9为本申请另一实施例提供的自动体外除颤仪的模块结构示意图。本实施例提供的自动体外除颤仪1和图8及其相关描述中提供的自动体外除颤仪1的结构基本相同，不同之处在于在本实施例中，放电模块850在对目标对象进行放电治疗之后，保存充电电路30中剩余的电量。
更进一步地，在放电模块850对目标对象进行放电治疗之后，充电模块840还在充电电路30保存剩余电量的基础上再对充电电路30进行充电。可选地，在放电模块850对目标对象进行放电治疗之后，充电模块840在在充电电路30保存剩余电量的基础上再对充电 电路30进行重叠至第二预设电量。
更进一步地，放电模块通过自动体外除颤仪1的放电模块850对目标对象进行放电治疗之后，感测模块830还感测目标对象的心脏活动对应的第二ECG信号；判断模块820还对第二ECG信号进行分析以判断目标对象是否满足电击条件；当目标对象满足电击条件时，放电模块850还对目标对象再次进行放电治疗。
进一步地，当目标对象满足电击条件但是在预设时间段内未收到电击指令时，放电模块850禁止对目标对象进行放电且保存充电电路30中的电量。
进一步地，请参阅图10，图10为本申请又一实施例提供的自动体外除颤仪的模块结构示意图。自动体外除颤仪1还包括：检测模块880。检测模块880，在对目标对象进行放电治疗前，检测自动体外除颤仪1的电极片10是否脱落。当自动体外除颤仪1的电极片10脱落时，放电模块850终止对目标对象进行放电且保存充电电路30中的能量。
进一步地，自动体外除颤仪1还包括：阻值获取模块890，用户获取两个电极片10之间的阻值。判断模块820还判断两个电极片10之间的电阻是否位于预设电阻值范围内。当两个电极片10之间的电阻值位于预设电阻值范围内时，判定电极片10粘结到目标对象上。
可以理解地，上述实施例所介绍的自动体外除颤仪1中的各个模块的更进一步的作用可以参照前面对除颤方法中具体步骤的介绍，在此不再详细展开介绍。举例而言，指令获取模块810用于获取开机指令并根据开机指令完成初始化，因此，指令获取模块810可以参照前面对除颤方法介绍时关于获取获取开机指令并根据开机指令完成初始化的步骤的相关描述。
