具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
在医疗领域、具体是临床医护的应用场景中，会发生与监测对象的医疗过程相关的事件，这些事件称为临床事件。临床事件可以包括但不限于：医护人员对监测对象所执行的临床操作、医护人员观察的监测对象的体征状况、医疗设备出现的异常情况等等。
临床事件可以辅助医护人员对监测对象进行诊断决策，因此，医护人员需要记录临床事件的相关信息。目前，大部分医疗设备不具备自动监测记录功能；或者，有些医疗设备需要由医护人员手动录入，临床事件种类繁多，手动录入方式较为繁琐，并且，在无菌操作场景中，医护人员需要避免与医疗设备等污染源进行直接肢体接触，这种记录方式不能满足临床需求。
本申请提供了一种临床事件的记录方法，应用在具有治疗和/或监护功能的医疗设备上，以实现对临床事件的便捷记录。医疗设备可以包括但不局限于 呼吸机、麻醉机、除颤机、心电图机、遥测设备、中央站及生命体征监测设备如监护仪等。
具体地，如图1所示，该临床事件记录方法可以包括步骤S101～S103。
S101：获取用户输入的语音信号。
其中，医疗设备上设置有音频采集模块，当用户需要记录临床事件的相关信息时，可以向医疗设备输入记载有该相关信息内容的语音信号，音频采集模块用于采集用户输入的语音信号。
需要说明的是，用户输入语音信号的时机点可能是不固定的，为了实现实时记录，音频采集模块可以自动保持在工作状态，以持续检测是否接收到语音信号。当然，如果基于节省电能、节省医疗设备计算资源等方面的考虑，可以由用户触发关闭音频采集模块，或者，医疗设备在音频采集模块的检测动作满足预设关闭条件的情况下自动关闭音频采集模块。其中预设关闭条件可以包括但不局限于，持续一定时长内并没有检测到语音信号等。
在音频采集模块被关闭的情况下，如果医疗设备检测到临床事件的记录启动指令，可以重新启动音频采集模块。记录启动指令的输入方式可以包括但不局限于以下几种方式。
例如，医疗设备上可以设置音频采集模块的实体开启按键，用户可以通过接触该按键输入记录启动指令；又如，医疗设备可以在功能设置等显示界面中，包含音频采集模块的开启按钮，用户可以通过触发该开启按钮输入记录启动指令；再如，医疗设备上可以设置光感模块，用户通过光感模块输入符合预设要求的记录启动指令，具体如，用户挡住光感模块的时长达到预设时长，以使光感模块检测到符合要求的光线变化情况，则确定检测到记录启动指令；再如，医疗设备上可以设置图像采集模块，用户向图像采集模块输入符合预设要求的手势动作(如画三角形、圆圈等动作)，则确定用户输入了记录启动指令。当然，以上几种开启音频采集模块的方式仅仅是示例说明，本领域技术人员能够想到的其他方式，均在本申请的保护范围之内。
S102：基于语音信号得到临床事件的相关信息，其中相关信息至少包括临床事件的内容和临床事件的发生时间两个信息项。
其中，音频采集模块采集到语音信号后，医疗设备可以对语音信号进行分析，以提取语音信号包含的语义内容，进而基于语义内容得到临床事件的相关 信息。具体地，语音信号的分析过程可以包括：语音信号预处理、语音特征提取、声学模型与模式匹配、语言模型与语言处理等步骤。语音信号的分析过程可以将人类的语言处理为计算机能够识别的信息。
语音信号可能直接指示也可能间接指示临床事件的相关信息。基于语音信号的指示，可以得到临床事件的相关信息。相关信息至少包括两个信息项：临床事件的内容以及临床事件的发生时间。需要说明的是，内容以及发生时间的获得方式，并非局限于两者都从语音信号的语音内容中获得，例如可以从语音信号的语音内容中获得临床事件的内容，基于语音信号的触发医疗设备自动提取设备系统时间作为临床事件的发生时间，等等。
以下具体说明如何根据语音信号，确定临床事件的内容以及发生时间。
为了便于理解提取临床事件的内容的过程，首先对其进行举例说明。临床事件的内容可以包括以下三类：
第一类临床事件：临床操作类事件，指的是医护人员作用于监测对象的临床操作，如拍背、清洁皮肤、口腔护理、吸痰、插管、喂养等床旁护理操作，又如机械通气、用药、急救、透析、体外膜肺氧合等床旁治疗操作。第二类临床事件：体征状况类事件，指的是医护人员观察到的监测对象的体征状况，如病患情绪、病患肤色、病患呼吸急促情况、病患感知意识情况、体征状况严重级别等等。第三类临床事件：设备异常类事件，指的是医疗设备出现的异常情况，如血氧检测附件脱落、呼吸机异常、输注泵故障、床旁吊桥故障等可能影响病人状态监测、治疗的异常问题。
在一种确定方式中，用户可以在语音信号中直接指示临床事件的内容及发生时间，从而医疗设备可以直接从语音信号中提取临床事件的内容及发生时间。
具体地，医疗设备可以工作在内容匹配模式，该工作模式下为了实现内容匹配，可以在医疗设备上预先定义用户输入语音内容的语音指令格式，语音指令格式中至少包含操作内容及操作时间两个信息项，当然还可以包含其他信息项。
例如，针对第一类临床事件可以设置语音指令格式为，操作内容+操作时间+操作效果+操作人；针对第二类临床事件可以设置语音指令格式为，观察时间+病患肤色+病患意识+病患情绪+重要级别，其中病患肤色+病患意识+病 患情绪整体作为事件内容；针对第三类临床事件可以设置语音指令格式为，异常内容+异常时间+异常发现人。需要说明的是，语音指令格式中的其他信息项并不局限于此，还可以是其他；另外，各个信息项的先后顺序并不局限于此，还可以是其他。需要说明的是，医护人员输入的语音信号中，各个信息项的先后顺序并不限定于与预先设置的语音指令格式中的顺序一致，医疗设备可以自动从语音信号中识别到信息项的内容，并自动将所识别到的内容与语音指令格式中的信息项相匹配。
在实际应用中，用户可以按照语音指令格式的定义，输入符合要求的语音信号。为了便于识别，用户可以预先输入语音或手势等类型提示指令，用于指示医疗设备所输入的语音信号对应的临床事件的类型。医疗设备采集到语音信号后，按照临床事件的类型对应的语音指令格式，从语音信号中提取临床事件的内容以及发生时间。当然，如果用户输入的语音信号中除了临床事件的内容以及发生时间外，还包括其他的信息项，医疗设备还可以提取其他的信息项；如果用户输入的语音信息中并不包括其他信息项，则提取的其他信息项的内容为空。
例如，用户通过语音输入类型提示指令“1”，提示医疗设备即将输入的是第一类临床事件。然后，用户输入语音指令格式中的各个信息项，例如用户输入“下午2点31分拍背”，根据第一类临床事件的语音指令格式，医疗设备提取到的操作内容为“拍背”，操作时间为“下午2点31分”，操作效果为空，操作人为空。
需要说明的是，用户语音信号中的操作时间可能较为简单，仅包含时、分这些要素，缺少年、月、日要素，医疗设备如果提取到格式不完整的操作时间，则可以从系统时间中获取语音信号所缺少的时间要素，将操作时间补充完整。例如，用户输入的操作时间为“下午2点31分”，医疗设备从系统时间中确定当前时间点为“2019年3月11日”，则将操作时间补充完整为“2019年3月11日下午2点31分”。
在实际应用中，用户输入的语音信号中可能包含非临床事件的信息，为保证所提取的临床事件的内容的准确性，可以预先设置操作内容集合，该集合内包含医护人员期望记录的所有临床事件的内容。例如，内容集合中包含有“拍背、清洁皮肤、口腔护理、吸痰、插管、喂养、机械通气、用药、急救、透析、 体外膜肺氧合”等等内容项。
采集到语音信号后，从语音信号中，检索与预设的临床事件内容相同或者相似的临床事件内容，其中相似的判定条件为，检索的内容与预设的内容的语义相似程度达到预设相似程度。如果检索到相同或相似的临床事件内容，则提取所检索到的内容作为临床事件内容，或者，将预设的内容作为用户输入的临床事件内容。例如，用户输入的语音信号为“拍拍背，下午2点31分”，医疗设备从中提取到的事件内容为“拍拍背”，与预设内容集合中的“拍背”达到预设相似程度，则将事件内容确定为“拍背”。
如果从语音信号中，未检索到与预设临床事件的内容达到预设相似程度的临床事件的内容，则说明用户输入的语音信号并不符合预设要求，进而可以输出提示信息，以提示用户重新输入语音信号。其中提示信息可以是语音、文字、警告音等各种形式。
以上确定方式，可以从一条语音信号中提取到临床事件的完整内容。但是，针对在某些特殊场景下，临床事件的内容包括多个内容项，多个内容项通过多条不同的语音信号获得。具体地，从语音信号中提取临床事件的第一内容项；展示与第一内容项关联的多个备选的第二内容项；获取用户输入的选择语音，确定选择语音对应的目标第二内容项；其中，临床事件的内容包括第一内容项和目标第二内容项。
例如，从一条语音信号中提取到第一内容项为“用药”，按照临床事件内容的记录要求，除了需要记录“用药”动作外，还需要记录所用药物的具体名称及剂量。但是，在日常临床工作中，医护人员可能使用口头语、缩略语或代号等表示药物名称，或者医护人员没有记住准确的药物名称，为了保证记录的规范化，可以在提取到“用药”这个事件内容之后，医疗设备展示包含多种药物名称的备选菜单，每种药物名称具有标号，医护人员根据实际用药情况，语音输入所用药物对应的标号，医疗设备确定该标号对应的药物名称为本次用药事件的药物名称。
需要说明的是，备选菜单中可以仅包含药物名称，而不包含有药物名称对应的标号。另外，备选菜单中的药物名称可以是预先设置的，且可以根据历史选择情况调整药物名称在备选菜单中的排序，以将经常使用的药物名称靠前显示。当然，所举的用药场景仅仅是一个示例说明，以上方案还可以应用在其他 类似的需要规范记录的场景中。
需要说明的是，除了上述的内容匹配模式，可以为医疗设备预先设置内容输入这种工作模式。在该工作模式下，医疗设备将语音信号的内容作为临床事件的内容。例如，某个时间点医护人员观察到病患状态较差，可以输入一条内容为“病人状态较差”的语音信号，进而医疗设备可以将“病人状态较差”记录为一条临床事件的内容，并将接收到该语音信息的时间作为临床事件的发生时间。
内容匹配模式与内容输入模式的切换，可以由用户完成。例如，音频采集模块启动后，医疗设备默认设置为内容匹配模式，如果接收到用户输入的“语音输入”的语音指示，则切换为内容输入模式。如果接收到用户输入的“语音匹配”的语音指示，则切换为内容匹配模式。需要说明的是，用户除了通过语音输入切换指令之外，还可以通过实体按键或者界面显示的切换按钮等其他形式输入。
除了以上几种确定临床事件内容的方式之外，还可以使用机器学习算法，对语音信号进行语义识别，以确定临床事件的内容。具体地，基于机器学习算法的一种语音识别过程可以包括两个阶段：训练和识别。训练阶段可以收集大量的语音语料，经过预处理和特征提取后得到特征矢量参数，最后通过特征建模建立训练语音的参考模型库；而识别阶段主要是将输入语音的特征矢量参数和参考模型库中的参考模型进行相似性度量比较，然后把相似性最高的输入特征矢量作为识别出的事件内容。当然，机器学习算法也可以是自学习算法，自主训练参考模型库。
机器学习算法的语义识别过程还可以是：接收到语音信号后，对语音信号进行语义分析，以得到临床事件的多个备选内容；响应于用户在多个备选内容中进行的选择操作，将用户选择的备选内容作为临床事件的目标内容。
机器学习算法的语义识别过程还可以是，接收到语音信号后，对语音信号进行语义分析，以从语音信号中提取能够表示语义内容的关键词，并将关键词作为临床事件的内容。例如，医护人员输入的语音信号为“插个小号管”，机器学习算法对该语音信号进行语义分析后，得到的临床事件的内容为“插管”。
基于以上说明可知，临床事件的发生时间可以直接从语音信号中提取到，即若从语音信号中检测到临床事件的发生时间，则提取语音信号中的临床事件 的发生时间。但是，某些情况下，用户输入的语音信号中可能并不包含有发生时间这个信息项，从而在语音信号中并未检测到临床事件的发生时间。面对这些情况，本申请提供以下几种方式，来确定临床事件的发生时间。
例如，为了简化用户的操作流程，允许用户在语音信号中省略发生时间。在这种情况下，医疗设备将接收到语音信号的时间确定为临床事件的发生时间。又如，临床事件由该医疗设备之外的其他设备执行，则在确定临床事件的内容后，可以从该执行设备中获取临床事件的发生时间。
需要说明的是，临床事件的相关信息除了包括，内容以及发生时间这两个基本信息项之外，还可以包括其他信息项，其他信息项可以包括以下几个信息项中任意一个或多个的组合：重要级别、类型、事件执行者。
基于语音信号除了可以得到基本信息项之外，还可以得到临床事件的其他信息项。具体方式可以参见上述基本信息项的获得方式，此处并不赘述。以下仅针对重要级别和类型进行具体说明。
若从语音信号中检测到临床事件的重要级别和/或类型，则提取临床事件的重要级别和/或类型；若从语音信号中未检测到临床事件的重要级别和/或类型，则基于语音信号得到临床事件的内容，并根据临床事件的内容与重要级别和/或类型之间的预设对应关系，确定临床事件的重要级别和/或类型。
具体地，一种实现方式是，用户可以直接在语音信号中输入临床事件的重要级别和/或类型，这种情况下，可以从语音信号中检测到这两个信息项。另一种实现方式是，可以预先设置每种临床事件的内容所对应的重要级别，以及可以预先设置每种临床事件的内容所对应的类型，从而，在确定临床事件的内容之后，根据上述对应关系确定出临床事件的重要级别和/或类型。需要说明的是，在该种实现方式中，如果某个临床事件的内容对于某个具体监测对象而言，重要级别与预设的重要级别不同，因此，用户可以直接在语音信号中输入重要级别的具体内容，从而医疗设备可以将输入的重要级别确定为该监测对象的重要级别。
又一种实现方式中，还可以通过手势动作来确定临床事件的重要级别和/或类型。即，预先约定每种重要级别和/或类型对应的手势动作，不同的手势动作表示不同的重要级别和/或类型，根据所检测到的用户输入的手势动作，来确定对应的重要级别和/或类型。
以上介绍了如何根据语音信号确定临床事件的相关信息。通过上述说明可知，医疗设备从语音信号中提取到一种操作内容，便记录为一条临床事件。例如，医疗设备提取到事件内容“拍背”，则记录为一条“拍背”事件；又如，医疗设备提取到事件内容“吸痰”，则记录为一条“吸痰”事件。
但是在某些情况下，并不能简单地根据操作内容区分不同的临床事件。例如，针对第二类临床事件即体征状况类事件，一条临床事件的内容可以包含多项，例如临床事件的内容包括：肤色潮红、呼吸急促、发汗、意识不清及寒颤等。此种情况下，医疗设备并不容易准确地确定一条完整的临床事件，因此，可以提示一条临床事件的语音信号的开始及结束位置。
一种提示方式可以是，用户在输入临床事件的语音信号之前，输入开始提示信息，在临床事件的语音信号输入结束之后，输入结束提示信息。开始提示信息与结束提示信息可以包括：语音、手势动作等各种形式。语音如“开始”“结束”，手势动作可以是预先定义的各种形式，如三角形手势表示开始、打钩手势表示结束。
S103：存储临床事件的相关信息。
其中，在医疗设备本地存储临床事件的相关信息，也可以将临床事件的相关信息发送至其他设备如中央站等进行存储。临床事件的相关信息可以单独存储，也可以与监测对象的监测数据一并存储。
一条临床事件的相关信息中可以包括多个内容项，例如，操作内容+操作时间+操作效果+操作人；又如，事件时间+病患肤色+病患意识+病患情绪+重要级别，等等。
若多条临床事件在特定项目上的相关信息相同，则将多条临床事件合并为一条临床事件进行存储。例如，如果多条临床事件的发生时间相同，则可以将多条临床事件合并为该发生时间对应的一条临床事件。具体如，一条临床事件为，2019年3月11日下午2点31分+拍背；另一条临床事件为，2019年3月11日下午2点31分+吸痰，则可以将该两条临床事件存储为一条临床事件，即2019年3月11日下午2点31分+拍背、吸痰。
由以上技术方案可知，本申请提供了一种临床事件的记录方法，该方法可以采集用户输入的语音信号，基于语音信号得到临床事件的相关信息，相关信息包括事件内容以及事件发生时间，进而存储临床事件的相关信息。可见，该 方法并不需要用户在设备上手动执行繁杂的录入操作，临床事件的记录方式简单便捷，用户体验较好。并且，该方法可以适用于一些避免直接接触设备的场景中如无菌操作场景，应用范围更广。
实际应用中，在记录临床事件的相关信息的基础上，还可以显示所记录的临床事件的相关信息。
一种显示方案是，可以在录入临床事件后，在医疗设备当前所显示的生理参数界面中，显示临床事件的相关信息。本显示方案是将临床事件显示在医疗设备的实时监测界面中，这样，医护人员及时查看所录入的临床事件的相关信息，并且发现录入错误的情况下，可以重新对相关信息中的某些信息项进行修正。需要说明的是，医疗设备的生理参数界面中可以包含事件回顾区域，该区域用于显示最近录入的临床事件的相关信息。其中所显示的最近录入的临床事件，可以是最近一段时间内发生的所有临床事件，也可以是最近一段时间内发生的某一类或某几类临床事件，还可以是最近录入的最后一条临床事件。
一种显示方案是，对历史时间段内的临床事件进行统计并显示，显示的结果可以方便医护人员了解本科室在历史一段时间内所处理的临床事件的整体情况。具体地，响应于用户对临床事件的查看指令，获得预设的历史时间段内发生的临床事件；以及显示临床事件的相关信息。
更具体地，若用户想要查看某段时间内发生的临床事件，则可以向医疗设备输入查看指令，查看指令中可以包含历史时间段的指示信息。历史时间段的长度及起止时间可以由用户输入，或者，医疗设备可以提供选择项，如过去一个月内、过去一个星期内等等选项，由用户选择某个时间段作为历史时间段。基于用户的查看指令，医疗设备将符合历史时间段要求的临床事件的相关信息进行显示。
在该种显示方案中，一种具体的实现方式是，对临床事件的相关信息进行排序，显示相关信息的排序结果。例如，按照临床事件的发生时间的先后顺序进行排序。或者，另一种具体的实现方式是，对临床事件的相关信息进行统计分类，显示相关信息的统计分类结果。例如，按照临床事件的类型进行分类，统计每种类型临床事件的个数，显示所有类型的临床事件以及每种类型的临床事件的个数。
以上显示方案是将临床事件的相关信息单独显示。另外，临床事件还可以 与历史生命体征数据结合显示。
具体地，根据医护人员的临床经验，临床事件的发生可能会对监测对象的生命体征数据的监测结果产生短时间的影响。例如，给患儿喂奶，可能会导致吞咽时呼吸停止，或者给患儿擦身换尿布等也有可能因为患儿临时体位问题导致呼吸暂停。
若医护人员后续发现生命体征数据监测结果异常，在分析异常波动的原因时，如果缺乏当时临床事件的相关信息，则很难分析出异常准确原因，或者，需要花费较多的时间与精力如查询护理记录单、询问当时值班人员等等，才能确定异常发生时的临床事件信息。可见，医护人员的操作极为不便。
本申请提供了一种临床事件的显示方法，如图2所示，该方法在上述图1所示的流程基础上，还包括步骤S104。
S104：将记录的临床事件的相关信息与监测对象的历史生理参数信息结合显示。
具体地，响应于用户对监测对象的生理参数的查看指令，显示包括监测对象在预设的历史时间段内的生理参数信息的生理参数界面；若存在与监测对象及历史时间段对应的临床事件，则在显示生理参数界面的同时，显示临床事件的相关信息。
更具体来讲，医护人员想要回顾某个监测对象的生理参数情况时，可以向医疗设备输入查看指令。查看指令中可以包含想要回顾的历史时间段的长度以及起止时间。历史时间段的确定方式可以参见上述临床事件的查看方案中的确定方式，此处并不赘述。另外，查看指令中还可以包含生理参数的类型，以指示医疗设备生成的生理参数界面中包含有哪种或哪些类型的生理参数的信息。例如，生理参数的类型可以包括但不局限于，血氧参数、血压参数、呼吸波形参数等等。再者，查看指令中还可以包含生理参数界面的类型，以指示医疗设备生成的生理参数界面的类型。例如，生理参数界面的类型可以包括但不局限于，波形图、趋势图、趋势表、报警回顾界面、全息波形回顾界面等等。
医疗设备响应于用户输入的对某个监测对象的查看指令，获得符合查看指令要求的生理参数信息，并生成包含该生理参数信息的界面。
需要说明的是，医疗设备还会判断是否存在对应于该监测对象且发生时间属于该历史时间段的临床事件，如果判断结果为存在，则在生理参数界面中添 加该临床事件的相关信息，从而在显示生理参数界面的同时，也显示该临床事件的相关信息。这样，医护人员在回顾监测对象生命体征数据的同时，还可以查看到生命体征数据采集时间内发生的临床事件的相关信息，临床事件的相关信息可以辅助医护人员分析生命体征数据异常波动的原因。
需要说明的是，在显示临床事件之前，还可以对临床事件进行筛选。筛选条件可以包括重要级别，即选择重要级别达到一定要求的临床事件进行显示。
为了更清晰地展示监测对象生理参数信息的变化情况与临床事件之间的关联性，可以根据时间这个要素，将两者关联显示在界面中。
具体地，在生理参数信息中，确定采集时间与临床事件的发生时间关联的目标生理参数信息；在与目标生理参数信息的展示位置关联的位置，显示临床事件的相关信息。
更具体来讲，生理参数界面中包含生理参数在历史时间段内的多个监测数据，不同的监测数据对应的不同采集时间，在这些监测数据中确定出采集时间与临床事件的发生事件相同的监测数据，所确定的监测数据即上述目标生理参数信息。
目标生理参数信息位于生理参数界面中的某个位置，则在该位置的关联位置，显示临床事件的相关信息。如此显示的目的，是通过显示位置的关联性，来表示两者在时间要素上的关联性。这样，医护人员可以直观地了解两者之间的关联性，并在异常诊断分析时，可能认为生理参数的监测数据的异常变化原因，可能是由于在该监测数据的采集时间附近发生了某个临床事件。
其中，上述目标生理参数信息与临床信息的显示位置之间的关联性，为本领域技术人员能够理解的可以表示两者之间对应关系的任何形式。
在一个示例中，在趋势图和/或波形图中对应临床事件的发生时间的位置，显示临床事件的相关信息。具体地，临床事件与生理参数信息的关联性体现在时间点上。因此以时间轴为关联，在时间轴上分别展示生理参数信息和临床事件，从而在一个时间点，可以查看到该时间点的生理参数信息以及临床事件。
在一个示例中，目标生理参数信息的展示位置与临床事件的展示位置较为接近。具体地，在目标生理参数信息的展示位置的附近位置，显示临床事件的相关信息；其中附近位置为与展示位置之间的距离满足预设要求的位置。
该种显示方式的一个应用场景是，生理参数界面中包含的生理参数的种类 可能为多个，某些临床事件的发生可能会影响某些特定生理参数的监测数值，则可以在该特定生理参数的目标生理参数信息附近显示该临床事件的相关信息。例如，生理参数界面中包含血压趋势图、呼吸波形图以及心率趋势图，如果待显示临床事件包括喂养，而由于喂养过程可能会影响监测对象的呼吸情况，则可以将事件内容为喂养的临床事件显示在呼吸波形图的目标生理参数信息的附近。
在一个示例中，若生理参数界面中包括至少一个生理参数对应的趋势图和/或波形图，则在趋势图和/或波形图中，确定目标生理参数信息的采集时间坐标；在生理参数界面的临床事件展示区域中，确定与采集时间坐标对应的目标位置，并在目标位置，显示临床事件的相关信息。
具体地，生理参数界面包含两个区域，一个区域用于显示生理参数的图形信息，图形包括波形图和/或趋势图；一个区域用于显示临床事件的相关信息，因此可以称为临床事件展示区域。两个区域共用同一时间坐标轴。
生理参数信息的显示方式为图形，图形中包含有时间坐标轴，首先确定目标生理参数信息的采集时间在时间坐标轴上的坐标(该位置即上述采集时间坐标)，然后在临床事件展示区域中，确定与该坐标对应的目标位置。其中，目标位置与采集时间坐标的位置对应指的是，目标位置在时间坐标轴上的坐标与采集时间坐标相同。进而，在临床事件展示区域的目标位置，显示临床事件的相关信息。
为了便于理解技术方案，结合具体示例进行说明。如图3所示，显示界面中包含有趋势图区域，该区域中包含有心率(HR)趋势图、血氧饱和度(SpO2)趋势图以及血压(BP)趋势图。图形中包含有时间坐标轴，时间坐标从-4h到0表示的是，趋势图包含的是从查看当前时间点开始之前4个小时内的监测数据。
趋势图下面的区域为临床事件展示区域，包含五个临床事件分组，分别为临床事件组A-临床事件组E，不同的临床事件分组表示不同类型的临床事件。临床事件分组内对应的背景色图标代表临床事件，背景色图标上显示的内容表示临床事件的内容。每个临床事件的展示位置，是由临床事件的发生时间在时间坐标轴上的位置决定的。医护人员根据时间坐标轴，可以将临床事件与趋势图中的监测数据产生关联，从而在分析趋势图中监测数据的变化情况时，可以参考临床事件区域内对应时间发生的临床事件的相关信息。
需要说明的是，用户可以触发趋势图，基于用户的触发操作生成用于表示该时间点的时间标记线；在时间标记线的附近显示目标生理参数的参数信息，并且若存在发生时间在该时间点关联的临床事件，则同时显示该临床事件的相关信息。其中，时间点的关联表示两个时间点相差在一定阈值范围内。如图3所示，基于用户的触发操作，在趋势图中生成游标卡尺线(竖线)，在游标卡尺线附近显示该时间点的心率值100、血氧饱和度95以及血压120/80(93)，并且显示该时间点关联的一条临床事件，临床事件的内容为“吸痰@9:30，×××护士”，表示在9点30分，某护士对病人进行了一次吸痰操作。
需要说明的是，临床事件的内容的显示样式并不局限于图3所示的添加背景色图标，还可以是其他形式。例如，并不添加背景色图标，或者为内容设置字体加粗、设置字体颜色等等。为了区分临床事件的不同，可以为不同的临床事件设置不同的显示样式。例如，可以根据临床事件的内容的不同，设置不同的显示样式；又如，可以根据临床事件的重要级别的不同，设置不同的显示样式；再如，可以根据临床事件的类型的不同，设置不同的显示样式；等等。其中，为不同重要级别的临床事件设置不同显示样式的一个具体示例为，将非常重要的临床事件，背景色设置为红色；将重要的临床事件，背景色设置为蓝色；将不太重要的临床事件，背景色设置为绿色。
需要说明的是，以上几种显示方式可以结合使用。一种结合使用情况是，将一部分临床事件显示在临床事件展示区域，将一部分临床事件显示在生理参数信息的附近位置。以图3所示的临床事件为例，针对给药这个临床事件，若检测到所给的药物会对血压测量数据产生影响，则可以将给药这个临床事件显示在血压测量趋势图附近。
临床事件的相关信息包括多个信息项，相关信息的显示方式可以包括多种。
一种显示方式为，先显示临床事件的内容，然后基于用户的触发再显示预先定义的一些更详细的信息项。具体地，显示临床事件的内容；响应于用户对临床事件的内容的触发操作，显示临床事件的相关信息中预先定义的目标信息项。
例如上述图3所示，背景色图标上显示的是临床事件的内容。如果用户想 要查看某个临床事件的其他信息项，可以点击某个临床事件，进而医疗设备获取该临床事件的目标信息项进行展示。目标信息项可以包含在信息界面中展示，信息界面可以悬浮在生理参数界面上，或者信息界面可以替换当前显示的生理参数界面。
需要说明的是，基于用户的触发操作显示哪些信息项可以预先定义，定义的这些信息项可以称为目标信息项。目标信息项可以表示临床事件更详细的信息。例如，显示临床事件的内容为用药，如果用户触发该临床事件的内容，进一步显示的目标信息项可以包括：用药的时间、所用药物的名称、所用药物的剂量、操作医护人员信息等。又如，显示临床事件的内容为设备故障，如果用户触发该临床事件的内容，进一步显示的目标信息项可以包括：故障发现时间、故障名称、故障发现人、重要级别等。需要说明的是，目标信息项中可以包含内容这个信息项，也可以不包含内容这个信息项。
另一种显示方式为，显示临床事件的内容展示符，基于用户的触发再显示预先定义的一些更详细的信息项。具体地，根据临床事件的内容，确定对应的内容展示符；显示临床事件的内容展示符；响应于用户对临床事件的内容展示符的触发操作，显示临床事件的相关信息中预先定义的目标信息项。
在该种显示方式中，预先设置临床事件的内容所对应的内容展示符。例如，为用药设置的内容展示符为药粒图标，为打针设置的内容展示符为包含针管图标，为血压测量设置的内容展示符为血压计图标，等等。内容展示符的形式可以包括多种，如图形、图标、图片、符号等等。
基于上述设置，临床事件的内容并非以文字形式显示，而是显示内容对应的展示符。用户点击某个内容展示符后，医疗设备展示该内容展示符对应的临床事件的目标信息项。需要说明的，目标信息项的预先定义方式参见上述说明，此处并不赘述。
需要说明的是，在展示临床事件的相关信息之后，如果医护人员发现临床事件的记录信息存在错误，如记录的用药量为2mg，实际用药量为1mg，或者发现存在需要补充的信息项，还可以对相关信息进行修改。具体地，响应于用户对目标临床事件的修改指令，根据修改指令对目标临床事件的相关信息进行修改。
其中，修改指令可以包括替换指示，也可以包括新增指示，也可以包含删 除指示。如果修改指令中包含替换指示，则使用用户输入的信息项内容替换所记录的信息项内容；如果修改指令包括新增指示，则在记录的相关信息中添加用户所输入的信息项内容；如果修改指令中包含删除指示，则在记录的相关信息中删除用户所指示的信息项内容。
新增指示的一个具体示例为，若临床事件的发生时间没有记录上，则用户可以通过语音信号或者其他方式补录该临床事件的发生时间。
用户也可以直接在包含目标信息项的信息界面中，点击某个信息项的内容进行修改。或者，为了实现临床事件的修改，可以在生理参数界面中包含事件设置按钮。用户点击事件设置按钮进入修改界面，修改界面中包含临床事件的备选项，用户在临床事件的备选项中选择某个目标临床事件进行修改。
另外，生理参数界面中还可以包含临床事件类型设置按钮，用户点击临床事件类型设置按钮，进入设置界面。在该设置界面中，用户可以设置每种类型临床事件包含的事件内容。再者，生理参数界面中还可以包含时间窗口，用户通过设置时间窗口内的是时间值，来指示生理参数界面中所显示的生理参数信息的选取范围。例如，用户设置的时间窗口值为4小时，则生理参数界面中包含的是历史4小时内的生理参数信息。
以上显示方案中，临床事件的相关信息是与历史时间段内的生理参数信息结合显示，除了这种显示方案外，医疗设备还可以显示生理参数的实时监测信息，临床事件的相关信息还可以与生理参数的实时监测信息结合显示。
具体地，在医疗设备当前所显示的生理参数界面中，显示临床事件的相关信息；其中生理参数界面中包括实时监测到的监测对象的生理参数信息。
更具体来讲，医疗设备可以显示实时监测界面，该实时监测界面用于显示生理参数的实时监测数据，医护人员通过该界面可以了解监测对象生命体征的实时情况。实时发生的临床事件可以显示在该实时监测界面中，具体的显示方式可以参见上述与历史生理参数的结合显示方案，此处并不赘述。
基于上述说明可知，本申请提供了一种应用在医疗设备上的临床事件记录方法，该方法包括：
获取用户输入的语音信号，基于语音信号得到临床事件的相关信息，其中相关信息至少包括临床事件的内容和临床事件的发生时间两个信息项；根据临 床事件的内容，确定对应的标识符；在医疗设备显示的生理参数界面中，显示临床事件的标识符。
其中，内容对应的标识符可以包括上述说明的内容展示符。另外，生理参数界面可以是上述说明的实时监测界面，也可以是包含历史监测数据的生理参数界面。

另外，本申请还可以提供一种应用在医疗设备上的临床事件记录方法，与上述各个临床事件记录方法不同的是，该方法并非基于语音信号而是基于手势动作记录临床事件。具体地：如图4所示，该方法可以包括如下步骤S401～S403。
S401：获取用户输入的手势动作。
S402：基于手势动作得到临床事件的相关信息，其中相关信息至少包括临床事件的内容和临床事件的发生时间两个信息项。
S403：存储临床事件的相关信息。
其中，基于手势动作得到临床事件的相关信息，具体实现方式包括：根据手势动作确定临床事件的内容；若从手势动作中未检测到临床事件的发生时间，则将接收到手势动作的时间确定为临床事件的发生时间；或者，若从手势动作中未检测到临床事件的发生时间，则从临床事件的执行设备中获取临床事件的发生时间。
根据手势动作确定临床事件的内容，具体实现方式可以包括：获得图像采集模块所采集到的临床操作图像，从临床操作图像中识别临床操作动作，并确定该临床操作动作对应的事件内容。例如，在临床事件发生现场设置有摄像头，摄像头可以在医护人员对病患进行临床操作的过程中采集图像，假设采集的是医护人员对病患吸痰过程的图像，那么医疗设备获得临床操作图像后，使用图像处理技术从中提取到临床操作动作的内容如吸痰，进而确定临床事件的内容为该临床操作动作所表示的内容。
根据手势动作确定临床事件的内容，具体实现方式还可以包括：
预先约定手势动作与临床事件内容之间的对应关系，例如预先约定手向下拍三下这个动作对应的临床事件内容为拍背，又如手画圈这个动作对应的临床事件内容为打针，等等。在实际应用中，医疗设备在检测到某种类型的手势动作后，便可以确定与该手势动作对应的临床事件内容。
根据手势动作确定临床事件的内容，具体实现方式还可以包括：从手势动作中提取临床事件的第一内容项；展示与第一内容项关联的多个备选的第二内容项；获取用户输入的选择手势动作，确定选择手势动作对应的目标第二内容项；其中，临床事件的内容包括第一内容项及目标第二内容项。
其中，临床事件的相关信息还包括：临床事件的重要级别和/或类型；则基于手势动作得到临床事件的重要级别和/或类型，具体实现方式包括：若从手势动作中检测到临床事件的重要级别和/或类型，则提取临床事件的重要级别和/或类型；若从手势动作中未检测到临床事件的重要级别和/或类型，则基于手势动作得到临床事件的内容，并根据临床事件的内容与重要级别和/或类型之间的预设对应关系，确定临床事件的重要级别和/或类型。
在一个示例中，上述方法还可以包括：响应于用户对临床事件的查看指令，获得预设的历史时间段内发生的临床事件；显示临床事件的相关信息。

其中，显示临床事件的相关信息，具体实现方式包括：在生理参数信息中，确定采集时间与临床事件的发生时间关联的目标生理参数信息；在与目标生理参数信息的展示位置关联的位置，显示临床事件的相关信息。
其中，在与目标生理参数信息的展示位置关联的位置，显示临床事件的相关信息，具体实现方式包括：在目标生理参数信息的展示位置附近位置，显示临床事件的相关信息；其中附近位置为与展示位置之间的距离满足预设要求的位置。
其中，生理参数界面中包括至少一个生理参数对应的趋势图和/或波形图；则在与目标生理参数信息的展示位置关联的位置，显示临床事件的相关信息，具体实现方式包括：在趋势图和/或波形图中，确定目标生理参数信息的采集时间坐标；在生理参数界面的临床事件展示区域中，确定与采集时间坐标对应的目标位置，并在目标位置，显示临床事件的相关信息。
其中，显示临床事件的相关信息，具体实现方式包括：显示临床事件的内容；响应于用户对临床事件的内容的触发操作，显示临床事件的相关信息中预先定义的目标信息项。
其中，显示临床事件的相关信息，具体实现方式包括：根据临床事件的内容，确定对应的内容展示符；显示临床事件的内容展示符；响应于用户对临床事件的内容展示符的触发操作，显示临床事件的相关信息中预先定义的目标信息项。
本申请还提供了一种应用于医疗设备的临床事件的记录方法，该方法包括：
获取用户输入的手势动作，基于手势动作得到临床事件的相关信息，其中相关信息至少包括临床事件的内容和临床事件的发生时间两个信息项；根据临床事件的内容，确定对应的标识符；在医疗设备显示的生理参数界面中，显示临床事件的标识符。
其中，生理参数界面中至少显示至少一个生理参数的趋势图和/或波形图；则在医疗设备显示的生理参数界面中，显示临床事件的标识符，具体实现方式包括：根据临床事件的发生时间，将标识符标记在趋势图和/或波形图的对应位置。
需要说明的是，有关该临床事件记录方法的说明可以参见上述基于语音信号的临床事件记录方法，此处并不赘述。另外，两种记录方法可以结合使用，即临床事件的某些信息项可以基于语音信号得到，某些信息项可以基于手势动作得到。与上述基于语音的临床事件时间记录方法相同，本方法也可以简化用户的记录操作，记录方式较为便捷。
另外，本申请还提供了一种医疗设备，包括:显示器、存储器以及处理器。其中：
显示器，显示器配置为显示信息；
存储器，存储器存储有可执行程序指令；
处理器，处理器执行可执行程序指令以实现上述任意一种临床事件的记录方法的步骤。
医疗设备的一个具体示例为监护仪，监护仪的一种具体结构如图5所示。图5提供了一种多参数监护仪中参数处理模块的系统框架图。
