Description

一种监护设备及其信息提示方法 技术领域
本发明涉及医疗设备领域，特别涉及一种监护设备及其信息提示方法。
背景技术

获取监测对象在目标时间段内的生理体征历史监测数据，以及所述生理体征的当前测量值；
基于所述历史监测数据和所述当前测量值分析得到所述生理体征的变化趋势，所述变化趋势用于指示所述生理体征的监测数据上升或下降的速度；

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。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、系统、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
下面对本发明中用于监护设备的生理状态信息展示方法进行详细描述，需 要说明的是，本发明提及的监护设备，不仅限于监护仪，也包括具有监护功能的有创/无创呼吸机、麻醉机、除颤仪、护士站、中央站等。
请参阅图1，图1为本发明实施例提供的一种用于监护设备的信息提示方法的流程示意图，包括：
步骤101、获取监测对象在目标时间段的生理参数数据。
本实施例中，监护设备对监测对象进行监护的过程中，可以获取监测对象在目标时间段的生理参数数据，此处不限定是如何获取监测对象在目标时间段的生理参数数据，例如可以通过参数采集模块来获取生理参数数据，或者从其他设备(中央站、其他监护设备)中获取生理参数数据。
步骤102、基于目标时间段的生理参数数据确定监测对象生理参数的基线值。
本实施例中，监护设备可以基于目标时间段的生理参数数据确定监测对象生理参数的基线值。在一实施例中，可以将监测对象在目标时间段的生理参数数据的平均值确定为基线值，该目标时间段为当前时刻之前的预设时长的时间段。
需要说明的是，监护设备可以采用监测对象过去一段时间(例如当前时刻的前30分钟)的生理参数数据的平均值作为基线值，监护设备也可以采用监测对象过去一段时间之前的某一段时间长度(例如当前时刻的前30分钟之前的1分钟)的生理参数数据的平均值作为基线值，具体不做限定。
需要说明的是，该监测对象的生理参数包括每搏输出量、心输出量、呼吸末二氧化碳、动脉压、中心静脉压、每博量指数、心输出量指数、中心性静脉血氧饱和度、心率中的至少一个，当然也还包括其他的生理参数，具体不限定。
步骤103、监测当前时刻监测对象生理参数的当前测量值。
本实施例中，监护设置可以监测当前时刻监测对象生理参数的当前测量值。
可以理解的是，目标时间段内监测对象生理参数的基线值与当前时刻监测对象生理参数的当前测量值具有关联关系，也就是说，假如需要对监测对象的中心性静脉血氧饱和度进行监测，则可以确定监测对象在目标时间段的中心性静脉血氧饱和度的基线值，同样需要监测当前时刻监测对象的中心性静脉血氧饱和度的当前测量值。
需要说明的是，监护设备可以根据监测对象的实际情况只监测监测对象的一个生理参数的趋势变化，并得到该一个生理参数的当前测量值，同样的还可以根据监测对象的实际情况监测监测对象的多个生理参数的趋势变化，得到多个生理参数的当前测量值，只要当前测量值与基线值相对应即可，具体不限定。
步骤104、将当前测量值与基线值进行对比，以得到对比结果。
本实施例中，监护设备在得到监测对象生理参数的基线值以及监测对象生理参数的当前测量值之后，可以将当前测量值与基线值进行对比，以得到对比结果，其中，该对比结果用于指示当前测量值相对于基线值的变化幅度。
可以理解的是，该对比结果可以有多种表达形式，例如纯数字(例如对比结果为5)、分数(例如对比结果为1/3)或百分比(例如对比结果为20％)。下面举例说明，例如监测对象的生理参数为为中心性静脉血氧饱和度，目标时间段内中心性静脉血氧饱和度的基线值为15，监测到当前时刻监测对象的中心性静脉血氧饱和度的当前测量值20，则得到的对比结果可以为5(两者的差值)、1/3(变化分数)或33.3％(变化百分比)。
步骤105、当对比结果大于预设阈值时，发出提示信息。
本实施例中，监护设备在得到对比结果之后，可以判断该对比结果是否大于预设阈值，当对比结果大于预设阈值时，则发出提示信息。例如该对比结果为5，该预设阈值为3，则发出提示信息。
在一个实施例中，监护设备发出提示信息之后，可以将该提示信息在监护设备的监测界面的第一区域展示，该监测界面用于展示监测对象在当前时刻的生理参数的趋势变化、监测对象在当前时刻的生理参数的参数值以及监测对象在第一时刻的生理参数的趋势变化，该第一时段为当前时刻之前的时段，其中，该第一时段可以与目标时间段相同，也可以不相同，具体不做限定。
下面结合图2进行说明：
请参阅图2，图2为本发明实施例提供的监护设备的监测界面的示意图，监护设备在确定对比结果大于预设阈值，发出提示信息的同时，可以将该提示信息在监测界面的第一区域(如图2中的区域201)显示，该监测界面还可以展示监测对象的生理参数的趋势变化(如图2中的区域202)、当前时刻监测对象的生理参数的参数值(如图2中的区域203)以及监测对象在第一时段内 的生理参数的趋势变化(也即监测对象的历史生理参数的趋势变化，图2中未示出)。
在一实施例中，可以将上述所说的当前时刻变更为一段时间，例如10分钟内，也就是说，可以监测监测对象在10分钟内的生理参数的平均值，并与基线值进行对比，得到对比结果，当对比结果大于预设阈值，发出提示信息。
在一实施例中，该提示信息可以包括当前测量值相对于基线值的变化百分比或当前测量值与基线值的差值(如图2中的区域201中显示的内容“HR、BP30min内变化＞20％”，图2中201显示的内容为监测对象的生理参数HR和BP在30分钟内的平均值(即当前测量值)与过去一段时间内的基线值的变化百分比)，当然也还可以包括其他内容，只要能将监测对象在当前时刻的生理参数的当前测量值相对于监测对象在目标时间段的生理参数的基线值的变化幅度显示即可，具体不限定。
综上可知，当前测量值可以包括某一时间点采集的监测对象生理参数的值，也可以包括与某一时间点对应的时间段采集的监测对象的生理参数的多个值的平均值。
需要说明的是，监护设备可以将提示信息在目标窗口进行展示，该目标窗口包含于监测界面，也就是说，监护设备可以将提示信息以弹窗的形式在监测界面进行展示。
当该提示信息以弹窗的形式进行展示之后，监护设备还可以接收用户的第一操作指令；响应于第一操作指令，并根据第一操作指令关闭目标窗口。当处监护设备将提示信息在目标窗口进行提示，用户在看到该提示信息，可以监护设备的监测界面上进行操作，监护设备根据用户的操作生成对应的操作指令，关闭目标窗口。
在一实施例中，生成第一操作指令的操作至少包括手势操作、滑动操作、点击操作以及声控操作中的一种，例如当用户对监测界面进行点击操作时，监护设备可以接收到该点击操作，此时，该点击操作即生成第一操作指令，也就是说，可以提前定义第一操作指令，例如提前定义滑动操作触发关闭目标窗口(如左滑操作、右滑操作、上滑操作以及下滑操作等等)，或者定义点击操作触发关闭目标窗口(如单击目标区域的操作或双击目标区域的操作等等)，或 者定义手势操作触发关闭目标窗口(如向左摆动手腕或手臂，向右摆动手腕或手臂，如四根手指收缩操作或者三根手指上滑操作等等)，或者定义声控操作触发关闭目标窗口(如收到关闭目标窗口的声音即关闭目标窗口)，上述仅为举例说明，并不代表对生成第一操作指令的操作进行限定。
在一实施例中，监护设备还可以统计当前周期内提示信息的发生次数，当前周期为当前时刻所处的周期；将当前周期内提示信息的发生次数以及当前周期内提示信息对应的监测对象的生理参数在监测界面的第二区域进行展示，第二区域为监测界面中与第一区域不同的区域。也就是说，监护设备在发出提示信息之后，还可以统计当前周期内(例如一天内)提示信息的发生次数，并将当前周期内提示信息的发生次数以及第一周期内的提示信息对应的监测对象的生理参数在监测界面的第二区域(参阅图2中的区域204)进行展示。也就是说，监护设备可以将第一周期内监测对象的各项生理参数发出的提示信息进行统计，并在监测界面的第二区域(参阅图2中的区域204)进行展示。
综上所述，本发明实施例提供的技术方案中，监护设备根据监测对象目标时间段的生理参数确定监测对象生理参数的基线值，与监测对象当前时刻的实时生理参数的当前测量值进行对比，当对比结果大于预设阈值时，发出提示信息，相对于现有技术中与预定义的阈值进行对比判断监测对象的生理参数是否异常来说，可以在监测对象的生理参数异常时，及时发出提示信息，可以更好的对监测对象进行监护。
请参阅图3，图3为本发明实施例提供的一种生理体征监测报警方法，包括：
步骤301、获取监测对象在目标时间段内的生理体征历史监测数据以及生理体征的当前测量值。
本实施例中，监护设备可以获取监测对象在目标时间段内的生理体征历史监测数据以及生理体征的当前测量值，其中，该目标时间段为当前时刻之前的时段内，该生理体征包括每搏输出量、输出量、呼吸末二氧化碳、动脉压、中心静脉压、每博量指数、心输出量指数、中心性静脉血氧饱和度、心率中的至少一个，当然也还包括其他的生理体征，具体不限定。
需要说明的是，该目标时间段可以为当前时刻之前的一段时间，例如当前 时刻的前30分钟，也可以为当前时刻之前的一段时间之前的某一段时间长度(例如当前时刻的前30分钟之前的1分钟)的生理参数数据的平均值作为基线值，具体不做限定。
步骤302、基于历史监测数据和当前测量值分析得到生理体征的变化趋势。
本实施例中，监护设备可以基于历史监测数据和当前测量值分析得到生理体征的变化趋势，该变化趋势用于指示生理体征的监测数据上升或下降的速度。具体的，监护设备可以基于历史监测数据计算目标时间段内的生理体征监测数据的平均值；计算当前测量值相对于平均值的变化百分比，将变化百分比确定为变化趋势。
需要说明的是，上述以当前测量值相对于平均值的变化百分比作为变化趋势进行说明的，当然也还可以采用其他的方式，例如当前测量值与平均值的差值，当前测量值与平均值的比值，当前测量值与平均值的差值与时间长度的比值，具体不做限定。
步骤303、当变化趋势大于预设阈值时，生成报警提示信息。
本实施例中，监护设备在确定变化趋势之后，可以判断该变化趋势是否大于预设阈值，当该变化趋势大于预设阈值时，生成报警提示信息。例如该变化趋势为70％，预设阈值为60％，则发出报警提示信息。
需要说明的是，图3中的步骤303与图1中的步骤104类似，图3中的步骤303发出报警提示信息之后的操作可以参阅上述对图1中的步骤104的描述，上述已经对发出提示信息之后的各种情况进行详细说明，具体此处不再赘述。
