Description

生命体征数据统计系统和监护仪 技术领域
本发明涉及一种监护仪，具体涉及一种生命体征数据统计系统和监护仪。
背景技术
对于临床危重或亚危重住院患者(例如病人)，特别是CCU、ICU患者，需要对其进行24小时的监护。监护仪可用于分析和显示由连接至病人的一个或者多个感测器测得的各种生理参数和/或心理参数。这些参数可以通过波形或者数值形式显示，其中波形可以显示一定时间周期(例如1个小时)内的参数值，而数值可以显示当前的监测值。从而医生可以使用监护仪监控病人的身体状况，并根据测得的参数判断病人的身体状况。对于临床危重或亚危重住院患者，医生在查房时，不但需要了解患者当前的生理参数，还要了解24小时甚至更长时间以来患者的总体情况，和一些对医学具有指导意义的特殊数据，而现有的监护仪却没有此功能，需要医生手动调取这些数据进行人工统计和分析，这不但导致医生花费大量的时间精力来整理和分析数据，而且在统计过程中容易出错，导致医生得出错误的判断。
发明内容
根据第一方面，一种实施例中提供一种生命体征数据统计系统,包括：
请求接收单元，用于接收请求显示生命体征数据统计结果的请求信息；
第一获取单元，用于基于请求信息获取统计数据的时间范围；
统计单元，用于对该时间范围内的生命体征数据根据设定的类别和各类别的统计项进行分类统计；
显示单元，用于将每一类的统计结果处理为可视化数据，使其分类显示在统计结果显示区，所述统计结果显示区为显示界面的至少部分区域。
根据第二方面，一种实施例中提供一种监护仪，包括：
信号采集模块，其用于从患者身体上采集患者的生命体征信号；
数据处理模块，其连接至所述信号采集模块，所述数据处理模块用于对生命体征信号进行处理，生成用以反映患者状态的生理参数，所述数据处理模块还用于接收用于请求显示生命体征数据统计结果的请求信息，基于请求信息获取统计数据的时间范围，对该时间范围内的生命体征数据根据设定的类别和各类别的统计项进行分类统计，将每一类的统计结果分类处理成可显示在统计结果显示区的可视化数据，所述统计结果显示区为显示界面的至少部分区域；
显示模块，所述显示模块与数据处理模块相连，用于对数据处理模块输出的数据进行显示。
依据上述实施例，由于可在监护仪上根据预设的分类对生命体征数据进行自动统计分析，并在显示屏上直观地将统计分析结果呈现给医生，增加了监护仪的功能，使得监护仪既能辅助医生快速了解了患者较长时间的总体情况，又节约了医生的时间和精力，为缓解医疗资源的紧张起到了积极的作用。

具体实施方式
下面通过具体实施例并结合附图对本申请作进一步详细说明。其中不同实施方式中类似元件采用了相关联的类似的元件标号。在以下的实施方式中，很多细节描述是为了使得本申请能被更好的理解。然而，本领域技术人员可以毫不费力的认识到，其中部分特征在不同情况下是可以省略的，或者可以由其他元件、材料、方法所替代。在某些情况下， 本申请相关的一些操作并没有在说明书中显示或者描述，这是为了避免本申请的核心部分被过多的描述所淹没，而对于本领域技术人员而言，详细描述这些相关操作并不是必要的，他们根据说明书中的描述以及本领域的一般技术知识即可完整了解相关操作。
另外，说明书中所描述的特点、操作或者特征可以以任意适当的方式结合形成各种实施方式。同时，方法描述中的各步骤或者动作也可以按照本领域技术人员所能显而易见的方式进行顺序调换或调整。因此，说明书和附图中的各种顺序只是为了清楚描述某一个实施例，并不意味着是必须的顺序，除非另有说明其中某个顺序是必须遵循的。
实施例一：
请参考图1，本实施例提供一种医疗监护仪100，用于对病人150进行监护，医疗监护仪100包括数据处理模块110、信号采集模块120和显示模块130。
信号采集模块120一端用于与患者身体接触，从患者身体上采集患者的生命体征信号，例如心脏搏动引起的脉搏信号、体温信号、血液对特定波段的光的吸收信号、心电信号、脑电信号等，信号采集模块120的另一端与数据处理模块110相连，例如通过接口与数据处理模块110相连，将生命体征信号输入到数据处理模块110。
数据处理模块110分别与信号采集模块120和显示模块130相连，接收生命体征信号，对生命体征信号进行处理，生成用以反映患者状态的生理参数，并将生理参数处理成可视化数据，然后将可视化数据发送到显示模块130，使显示模块130在显示界面显示可视化数据。常规的生理参数例如包括血压、血氧、心率、体温、心电图等。
显示模块130包括提供显示界面的显示屏，显示屏可以是触摸式或非触摸式。
通常情况下，监护仪在其显示屏上以图形或数值的方式显示常规生理参数，本实施例中，数据处理模块110还包括生命体征数据统计系统，当用户(例如医生)需要查看患者一段较长时间内的汇总情况和统计分析结果时，生命体征数据统计系统根据医生的请求，对设定时间范围内指定的生命体征数据进行统计分析，并在显示屏上显示统计分析的结果。例如，可以弹出显示统计分析结果的窗口，统计分析结果的窗口可以是整个显示界面的一部分，也可以是整个显示界面，例如统计分析结果的 窗口覆盖了常规生理参数的显示窗口。统计分析结果的窗口可以由用户通过操作来关闭该窗口，也可以是设定时间无操作后自动关闭统计分析结果的窗口，并重新显示常规生理参数的显示窗口。指定的生命体征数据可以是心电数据、脉搏数据、血氧数据、脑电数据等，心电数据是指根据心电信号通过运算或统计得到的参数，脉搏数据是指根据脉搏信号通过运算或统计得到的参数，血氧数据是指根据血氧信号通过运算或统计得到的参数，脑电数据根据脑电信号通过运算或统计得到的参数。监测的各种生命体征数据保存在存储器中，每一数据包括数值和监测时间。下面以对心电数据进行统计分析为例说明本发明的具体实施方式。
为了对心电数据进行统计分析，预先根据医生比较关注的事项确定心电数据的统计分类和每一类的统计项，例如在系统中预先保持一分类表，其中记录心电数据的统计分类和每一类的统计项。本实施例中，对心电数据的统计分为四类，包括心率、ST、QT/QTc和心律失常事件，在其它的实施例中，可以统计心电数据中的更多分类或更少分类，其统计分类中可以包括心率、ST、QT/QTc和心律失常事件中的至少一个，也可以不包括心率、ST、QT/QTc和心律失常事件中的任何一个。对于每一分类，还规定其统计项，例如，对于心率，其统计项包括当前统计时间段内的心搏总次数、平均心率、最快心率及其发生时间、最慢心率及其发生时间等。对于ST，其统计项包括当前统计时间段内的每个心电导联ST抬高和压低阵次、每个心电导联的ST最大抬高值和最大压低值及其发生时间等。对于QT/QTc，其统计项包括当前统计时间段内的最大QT值、最小QT值和平均QT值，以及最大QTc值、最小QTc值和平均QTc值等。对于心律失常事件，其统计项包括当前统计时间段内发生所有心律失常事件及每一类心律失常事件发生的总次数等。当然，本领域技术人员应当理解，在其它的实施例中，也可以采用不同于本实施例中统计项，或者统计分类和/或统计项可设计为由用户来选择。
请参考图2，生命体征数据统计系统200包括请求接收单元201、第一获取单元202、统计单元203、第二获取单元204、第三获取单元205、第四获取单元206和显示单元207。
请求接收单元201用于接收请求显示生命体征数据统计结果的请求信息，在一种具体实施例中，该请求信息基于用户在显示界面上的选定操作而产生，因此请求接收单元201与显示模块130相连，如图2中实 线所示。在另一具体实施例中，该请求信息基于用户对监护仪上设置的输入单元的状态切换而产生，因此请求接收单元201与输入单元连接，输入单元可以是按键、具有不同档位的旋钮或拨动开关等，如图2中虚线所示。本实施例中，请求信息用于请求显示心电数据的统计结果。
第一获取单元202与请求接收单元201相连，用于基于请求信息获取统计数据的时间范围，并将获取到的时间范围输出给统计单元203。一种具体实施例中，时间范围可以是预先设置在系统中的一个时间段，例如最近24小时，或最近12小时等，第一获取单元202可以从时间设定表中获取统计数据的时间范围，如图2所示。在另一具体实施例中，第一获取单元202接收到请求信息后，可以弹出一对话窗，要求用户输入统计数据的时间范围，当用户输入后，第一获取单元202将该时间范围输出给统计单元203。
统计单元203用于对该时间范围内的生命体征数据根据设定的类别和各类别的统计项进行分类统计分析。本实施例中，统计单元203分别与第一获取单元202和存储器相连，接收第一获取单元202输出的时间范围，从保持在存储器中的分类表中获取心电数据的统计分类和每一类的统计项，本实施例中，对心率、ST、QT/QTc和心律失常事件等心电数据进行分类统计，因此从存储器中读取该时间范围内的这些类别的心电数据进行统计分析，通过统计和分析得出心率、ST、QT/QTc和心律失常事件的各统计项，并将统计分析结果发送给显示单元207。
第二获取单元204用于获取对每一类别所设定的特别统计项。特别统计项通常是比较重要的统计项，其对医生判断患者的病情具有一定程度的指引作用。对于某一类的心电数据，其可能规定有特别统计项，也可以没有特别统计项。一种具体实施例中，特别统计项也可以在分类表中进行规定，因此第二获取单元204也与存储器连接，从保存在存储器中的分类表中读取每一类别的特别统计项。例如对心率的特别统计项是最快心率和最慢心率，ST没有特别统计项，对QT/QTc的特别统计项是最大QT值、最小QT值、最大QTc值和最小QTc值，对心律失常事件的特别统计项是某一种或某些种心律失常事件，例如停博、单发室早等。本领域技术人员应当理解，对于特别统计项的规定，可根据不同的需求进行设定。在实际应用中，可采用系统默认的特别统计项，也可以允许医生修改特别统计项。第二获取单元204与第三获取单元205相连， 第二获取单元204将从存储器中读取到的特别统计项输出到第三获取单元205。
第三获取单元205还与统计单元203相连，用于在每一类的统计内容中获取特别统计项的统计结果，例如，对于特别统计项最快心率，第三获取单元205在从心率的统计结果中得到最快心率为144bpm，发生于09:01:00；对于特别统计项最慢心率，第三获取单元205在从心率的统计结果中得到最慢心率为46bpm，发生于04:01:00；对于特别统计项停博，第三获取单元205在从心律失常的统计结果中得到停博的次数是53次。第三获取单元205与第四获取单元206相连，将得到的特别统计项的统计结果发送给第四获取单元206。
第四获取单元206分别与存储器和显示单元207连接，从预设时间范围内的心电数据中提取包含该特别统计项统计结果的前后预定时间段(例如20秒或30秒)的波形数据，并将该波形数据作为该特别统计项的典型波形数据发送给显示单元207。
显示单元207用于将接收到数据处理为可视化数据，使其显示在显示界面上。本实施例中，显示单元207分别与统计单元203和第四获取单元206相连，一方面，显示单元207将统计单元203发送的对每类心电数据的统计分析结果处理为可视化数据，使其分类显示在统计结果显示区，统计结果显示区为显示界面的至少部分区域。另一方面，显示单元207将发送的典型波形数据处理为可视化数据，使其分别显示在波形显示区，波形显示区为显示界面的至少部分区域。本实施例中，统计结果显示区和波形显示区为显示界面上上下并排的两个区域，如图3所示。统计结果显示区分为若干子区域，每个子区域显示一类心电数据的统计结果，例如图3中，统计结果显示区分为心率统计区S1、ST统计区S2、QT/QTc统计区S3、心律失常统计区S4。波形显示区S5也分为若干子区域，每个子区域显示一个特别统计项的典型波形数据。在其他实施例中，统计结果显示区和波形显示区也可以为显示界面上左右并排的两个区域。
本实施例中，当对各类生命体征数据进行统计分类统计后，还可以根据预设的特别统计项，显示该特别统计项的典型波形，以供医生查看特别统计项发生前后的波形情况，为医生进行综合判断提供直观的依据。
本领域技术人员应当理解，在另外的实施例中，生命体征数据统计 系统200可以不包括第二获取单元204、第三获取单元205和第四获取单元206，此种情况下，显示界面将不显示典型波形数据。
实施例二：
本实施例在实施例一的基础上增加了典型波形数据设置功能，如图4所示，生命体征数据统计系统200还包括第一定位单元208和更新单元209。
第一定位单元208与显示模块130连接，用于捕获用户在波形显示区的选中操作，选中操作可以是用户通过控制光标移到预定位置后的点击操作，当显示模块130包括触摸屏时，选中操作还可以是用户对预定位置触摸操作。当捕获到用户在波形显示区的选中操作后，第一定位单元208根据选中操作的位置坐标确定用户选中区域所对应的特别统计项。第一定位单元208还与第四获取单元206相连，将用户选中区域所对应的特别统计项发送给第四获取单元206。
第四获取单元206在预设时间范围内的生命体征数据中查找与该特别统计项的统计结果相关的至少一个相关数据，然后提取包含所述相关数据的前后预定时间段的至少一组波形数据，并将该至少一组波形数据作为该特别统计项的备选波形数据发送给显示单元207。显示单元207将该特别统计项的典型波形数据和备选波形数据处理为可视化数据，使其分行显示在弹出的选择窗口，并允许用户在典型波形数据和备选波形数据中进行选择。相关数据可以是与该特别统计项的统计结果相近的数据，例如，特别统计项为最快/最慢心率，与最快/最慢心率相近的数据是次快/次慢心率，按此顺序对应选取多个典型心电波形供用户选择，如图5所示。
更新单元209分别和第四获取单元206和显示单元207相连，用于在接收到用户对多个典型心电波形的选择结果后，将该特别统计项最初显示的典型波形数据更新为用户所选择的典型波形数据。
本实施例可支持用户手动选择非受扰心电波形作为典型波形。当用户对特别统计项的典型波形有疑问时，可通过触摸或点击特别统计项的典型波形所在区域，系统会根据用户的需求，自动选取多个对应心电波形供用户选择，并将用户选择的波形设置为典型心电波形，以防其中某一个典型波形是由于心电信号受到干扰产生的伪差。
实施例三：
本实施例在实施例一、二的基础上增加了显示全息波形的功能，生命体征数据统计系统还包括第二定位单元，第二定位单元用于捕获用户在统计结果显示区的选中操作，根据选中操作的位置坐标确定用户所选中的统计项；显示单元基于选中操作弹出生命体征数据的全息波形显示窗，并对与用户所选中的统计项相关的波形进行处理使其显示在全息波形显示窗的当前窗口。如图6所示，当用户触摸或点击心率统计区时，系统弹出全息波形的显示窗口，所谓全息波形，是指该波形包括整个统计时间范围的波形数据，由于时间较长，所以无法在一个二维图中显示，因此通过分割时间段在上下并排的若干个二维图中显示，例如在第一个二维图中显示第1分钟的波形数据，在第二个二维图中显示第2分钟的波形数据，依此类推，显示全部统计时间范围的波形数据，用户可通过滚动条显示前后的波形。显示全息波形，可使医生方便查看患者的全部心电波形。本发明实施例中，为方便医生观察特别统计项的波形，将用户所选中区域所对应的特别统计项所发生时刻的波形或特别统计项的典型波形显示在全息波形显示窗的当前窗口，以避免医生前后翻找。更优选的，在全息波形上标记出特别统计项的典型心电波形，并在全息波形显示窗的下面区域放大显示该典型心电波形，以方便医生观察。如图6所示，当用户点击心率统计区S1时，弹出窗口显示心电(ECG)全息波形，并将包含特别统计项最快心率所发生时间在内的1分钟心电波形显示在窗口的第一排，并在1分钟心电波形上以矩形框标记出最快心率的7秒时间的典型心电波形，在窗口的下面区域放大显示该典型心电波形。
上述各单元可以制成一独立模块，也可以集成在数据处理模块中，其中显示单元还可以是显示模块的一部分。
实施例四：

步骤301，接收用于请求显示心电数据统计结果的请求信息。

步骤313，在接收到用户的选择后，更新该特别统计项的波形显示区显示的典型波形数据。
步骤314，显示心电全息波形。根据选中操作的位置坐标确定用户所选中的统计项，基于选中操作弹出生命体征数据的全息波形显示窗，并将用户所选中的特别统计项的典型波形显示在全息波形显示窗的当前窗口。
本领域技术人员可以理解，上述实施方式中各种方法的全部或部分步骤可以通过程序来指令相关硬件完成，该程序可以存储于一计算机可 读存储介质中，存储介质可以包括：只读存储器、随机存储器、磁盘或光盘等，数据处理模块可通过执行程序实现上述功能。
以上应用了具体个例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本领域的一般技术人员，依据本发明的思想，可以对上述具体实施方式进行变化。
