静脉输液治疗是临床上使用频率较高的给药途径之一，医院每天接纳的输液患者数量很大。传统的挂瓶输液方式，无法准确控制输液的速度以及给药的多少，对医护人员及患者家属的要求较高。鉴于这种情况，开发了输液泵、注射泵等医疗输注设备。这些设备的使用在一定程度上减小了医护人员的工作强度。但是随着病区输液的大量使用，输注设备数量的增多，医护人员难以实时掌握各个病区的各个输注设备的状态。医护人员的工作负担很大，而且稍有不慎，处理不及时就会引起医疗差错，发生不良事件。
因此，需要一种实时可靠的输液监护系统来为医护人员提供辅助。

具体实施方式
在下文中将结合附图对本发明的示范性实施例进行描述。为了清楚和简明起见，在说明书中并未描述实际实施方式的所有特征。然而，应该了解，在开发任何这种实际实施例的过程中必须做出很多特定于实施方式的决定，以便实现开发人员的具体目标，例如，符合与系统及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
在此，还需要说明的一点是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的设备结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
图1示出了根据本申请的一个实施例的输液监护系统的示意性结构框图。如图1所示，输液监护系统100包括：一个或多个输注设备101，用于执行输液操作；一个或多个中继设备102，每一个中继设备可通信地连接至多个输注设备101并转发来自输注设备101的相关信息；以及数据处理装置103，可通信地连接至中继设备102并对来自中继设备102的数据进行处理。
其中，图1中示出了多个输注设备101-1、……、101-k、……101-n的，多个中继设备102-1、……、102-n。在本文中，在不需要进行特别区分的情况下，将去掉参考标号的后缀而记为输注设备101、中继设备102。并且，本技术也可以适用于仅有一个输注设备以及/或者仅有一个中继设备的特殊情形。此外，本文中还将具有相同名称的部件的命名用 第一、第二、……进行区分，但是应该理解，这仅是为了区分的目的，并不代表任何顺序或其他含义。
输液监护系统100例如可以布置在一个病区内或者覆盖几个病区的范围内。输注设备101例如为如前所述的输液泵、注射泵等，用于对患者进行输注操作。输注设备101中可以包括控制单元，以对输液的过程进行控制。
在该系统100中，输注设备101产生的数据经由中继设备102转发至数据处理装置103，数据处理装置103基于这些数据为用户比如医护人员提供用于输液监护的信息。由于设置了中继设备102，一方面，在数据处理装置103能够连接的设备数量一定的情况下，中继设备102的加入增加了能够监视的输注设备101的数量，扩展了监视范围；另一方面，与数据处理装置103的较复杂的通信可以由中继设备102完成，而输注设备101仅需要提供原始数据即可，大大减轻了输注设备101的处理负荷，提高了输注设备101的可靠性。
图2示出了输注设备101的一个示意性功能模块框图。在该示例中，输注设备101包括：第一通信接口1011，被配置为将输注设备101的相关信息发送给中继设备102。例如，该第一通信接口可以包括如下之一：串口、通用串行总线(USB)接口、无线通信接口。
即，输注设备101通过第一通信接口1011以有线或无线方式将输液监视所需的信息发送给中继设备102。
其中，输注设备的相关信息包括如下至少之一：输注设备的标识、使用输注设备的用户的信息、当前流速、预计输液量、已输液量、药物名称、工作模式、Bolus速度、KVO速度、输注设备的工作状态指示。其中，输注设备的标识用于指示该信息对应于哪一个输注设备，使用输注设备的用户(例如，患者)的信息可以是床位信息或者患者本身的信息。当前流速指的是输液的速度，比如可以用单位时间内落下液滴数或者单位时间内输注液体容积来表示。工作模式指示了输液速度的设置方式，例如可以包括速度模式、时间模式等，速度模式例如为按照设定的速度值完成一定的输液量，时间模式例如为按照设定的时间完成一定的输液量。预计输液量(也简称为预输量)和已输液量(也简称为已输量)分别指的是要输液量和已经输注的液体量。此外，KVO(Keep Vein Open) 指的是在输液完成后，为了保持管路畅通，输注设备会以很小的速度继续输液，KVO速度指的是这种输液的速度。Bolus指的是提供大丸剂量快速输液，比如用于患者抢救时，Bolus速度指的是该速度。输注设备的工作状态指示表示对该输注设备的总体工作状况的判断，比如是处于正常工作状态还是异常工作状态，异常工作状态还可以划分为不同等级或类型的紧急情况，以用于提示医护人员进行处理。异常工作状态例如包括输液完成、拉杆松脱等。
可以看出，输注设备的相关信息包括相应输注设备的具体工作参数和工作状态指示，其反映了相应输注设备的实时工作状态，因此可以用于医护人员对输注设备进行实时监视，并及时地执行适当的处理。
例如，输注设备101可以将要发送的相关信息用结构体进行封装，并将实际数据赋值给结构体，加入帧头帧尾和校验和来进行发送。更确切地，输注设备101可以使用对应于第一通信接口1011的格式来进行上述相关信息的发送。
其中，第一通信接口1011可以周期性地发送相关信息。周期性地发送既可以实现简单的操作又可以保证数据的稳定性。例如，如果某次发送由于某种原因而使得发送失败，则在下一周期将会重新发送。只要周期设置地足够短，仍可以保证实时数据的准确性和及时性。
在一个示例中，第一通信接口1011还可以被配置为禁止接收数据。即，输注设备101仅发送数据而不接收来自外部的任何数据，这样可以有效地保证输注设备的安全性。
当然，第一通信接口1011也可以被配置为接收数据，例如接收中继设备转发的来自数据处理装置的控制指令等。这样，医护人员可以通过对数据处理装置发出指令来远程操作输注设备。
如图2的虚线框所示，输注设备101还可以包括：第一加密单元1012，对输注设备的相关信息进行加密。第一加密单元1012可以使用已有的各种加密技术来对相关信息进行加密，这并不是限制性的。具体地，第一加密单元1012可以采用硬件或固件的方式加密，也可以采用软件的方式加密。在采用软件加密的情况下，第一加密单元1012例如可以实现为处理器，该处理器例如可以实现为芯片。通过包括第一加密单元1012，可以提高信息传输的安全性。
图3示出了根据本申请的实施例的中继设备102的一个示意性功能模块框图。如图3所示，中继设备102包括：第二通信接口1021，通过无线或有线的方式向数据处理装置发送数据。
无线的方式例如包括如下之一：WiFi、蜂窝通信技术、蓝牙。更一般地，可以采用任何无线通信技术。
当输注设备101直接与数据处理装置进行无线通信的通信质量较差时，例如可以将输注设备通过串口等方式连接到无线通信质量较好的中继设备102，由中继设备102将相关信息转发至数据处理装置，从而实现了对这些输注设备的可靠的实时监护。
此外，如图3中的虚线框所示，中继设备102还可以包括：第一显示单元1022，对如下中的至少一个进行显示：输注设备的相关信息、输注设备的当前连接状态、中继设备与数据处理装置的连接方式。
其中，输注设备的相关信息例如包括以上列出的相关信息中的至少一个。输注设备的当前连接状态例如可以包括连接良好、连接断开等状态。中继设备与数据处理装置的连接方式例如包括有线连接或无线连接、或者连接的具体方式比如WiFi、移动通信网络比如3G、4G等。应该理解，这里仅给出了第一显示单元1022显示的示例，但是并不限于此，而是可以根据实际需要适当地显示任何内容。第一显示单元1022例如可以为各种显示设备，比如液晶显示设备、CRT显示器、OLED显示器等。
如图3中的另一个虚线框所示，中继设备102还可以包括：第二加密单元1023，用于在转发所接收到的相关信息之前对该相关信息进行加密。类似地，第二加密单元1023可以使用已有的任意加密技术执行加密，这并不是限制性的。具体地，第二加密单元1023可以采用硬件或固件的方式加密，也可以采用软件的方式加密。在采用软件加密的情况下，第二加密单元1023例如可以实现为处理器，该处理器例如可以实现为芯片。通过包括第二加密单元1023，可以进一步提高信息传输的安全性。
图4示出了根据本申请的一个实施例的数据处理装置103的示例性功能模块框图。如图4所示，数据处理装置103包括：分离单元1031，被配置为从接收的数据中分离每个输注设备的数据；显示控制单元1032，被配置为针对每个输注设备，基于该输注设备的数据进行显示控制；以及第二显示单元1033，被配置为基于显示控制来分别显示各个输注设备 的工作状态。
其中，分离单元1031和显示控制单元1032可以由一个或多个处理器实现，处理器例如可以实现为芯片。
如前所述，数据处理装置103从一个或多个中继设备102获取多个输注设备的相关信息，这些信息反映了相应输注设备的工作状态。相应地，如图4中的虚线框所示，数据处理装置103还包括第三通信接口1034，被配置为从中继设备接收数据。
为了获得每一个输注设备的工作状态，分离单元1031需要对接收的数据按照输注设备进行分离。针对每一个输注设备，在分离出其相关信息之后，显示控制单元1032基于该相关信息获得相应输注设备的工作状态，如前所述，这里所述的工作状态可以包括该输注设备的总体工作状况的指示比如是处于正常工作状态还是异常工作状态，异常工作状态还可以划分为不同等级或类型的紧急情况。此外，工作状态还可以包括相关信息中的具体工作参数，比如其对应的用户(即患者)信息、输注的药物、当前速度、工作模式等。
示例性地，异常工作状态还可以包括输注设备是否关机、是否离线等状况。相应地，如果输注设备在预定时间内没有向中继设备发送数据时，则认为该输注设备处于离线状态。在输注设备由于某种原因比如完成输注或电量低而关机时，会在关机前向中继设备发出指示以告知中继设备其将要关机，从而数据处理装置103可以获取其关机的信息。
在一个示例中，输注设备提供的使用输注设备的用户的信息为床位信息。分离单元1031可以使用该床位信息来匹配患者信息，以使得第二显示单元1033可以针对不同的患者进行显示。在另外的示例中，输注设备提供的使用输注设备的用户的信息也可以为患者自身的信息。
如图4中的另一个虚线框所示，数据处理装置103还可以包括：安全单元1035，被配置为在输注设备以及/或者中继设备对所传递的数据进行了加密的情况下，对所接收的数据执行解密操作。其中，安全单元1035采用与加密算法对应的解密算法来执行解密操作。
此外，数据处理装置还可以进一步与医院信息化系统(HIS)通信，以将获得的输注监视数据提供给HIS，实现医院大数据的整合，为临床研究提供数据来源。在这种情况下，第三通信接口1034向HIS发送从中 继设备接收的数据。
在一个示例中，安全单元1035还可以对上述数据进行加密，并且第三通信接口1034向HIS发送加密后的数据。通过这样的方式，实现了从输注设备到HIS的多层加密，为数据安全提供了有利的保障。
其中，安全单元1035也可以由一个或多个处理器实现，处理器例如可以实现为芯片。
如图4中的另一个虚线框所示，数据处理装置103还可以包括：存储器1036，被配置为存储所接收的数据。例如，可以建立用于保存输注过程信息的数据库，该数据库可以自动地周期性地备份，也可以手动进行备份，以保证数据存储的安全性。该数据库的数据例如可以导出为易读文件，以备后续查阅。
第二显示单元1033基于分离出的各个输注设备的数据显示相应输注设备的工作状态。图5示出了所显示的一个输注设备的工作状态的示例的图。其中，第一行显示了床位号和患者姓名，第二行和第三行显示了输液的速度，相应地，第八行和第九行显示了工作模式为速度模式。第四行至第七行显示了预输量和已输量。并且，图中右侧还示出了输液的示意性图示和药物名称。在最后一行，示出了该输注设备的工作状态为“正在输液”，右下方的圆形标记S可以用于用颜色来示出该工作状态，比如示出为绿色表示工作状态正常。此外，还可以将S显示为红色来表示非正常状态比如拉杆松脱等，将S显示为灰色来表示输液设备的离线或关机状态。应该理解，图5仅示出了一种示例，可以使用的显示方式并不限于此。
此外，在存在多个输注设备时，可以在显示屏内平铺显示多个图5所示的显示示例。具体地，显示控制单元1032执行显示控制以使得在一个视图内显示所有输注设备的工作状态，例如可以对所有输注设备的工作状态进行归类统计，并按照工作状态来分组显示，从而可以容易地发现并定位需要紧急处理的输注设备。
在一个示例中，第二显示单元1033可以用不同的颜色以及/或者动画来显示输注设备的不同的工作状态。其中，这里所述的工作状态可以仅指工作状态是否异常的指示，也可以包括各个具体工作参数。类似地，第二显示单元1033例如可以为各种显示设备，比如液晶显示设备、CRT 显示器、OLED显示器等。
在使用不同的颜色以及/或者动画比如闪动显示不同的工作状态时，可以使得医护人员直观地、快速地获知输注设备的情况并及时进行有效处理，提高患者对医护工作的满意度。
示例性地，显示控制单元1032可以在存在工作状态异常的输注设备时生成向用户(例如医护人员)发出提示的提示信号。其中，该提示可以是听觉上的。例如，针对发生不同等级的异常的输注设备、关机的输注设备、离线的输注设备，生成不同的声音信号，以提醒医护人员。声音信号的强弱还可以根据需要适当地设置。此外，该提示也可以是视觉上的，例如如上所述采用不同的颜色和/或动画进行提示。
综上所述，根据本实施例的输液监护系统通过采用中继设备进行数据转发，增加了可以实时监视的输液设备的数量，扩展了实时监视范围，提高了监视的可靠性。此外，通过采用数据处理装置实现监视数据的可视化显示，使得医护人员能够直观地、快速地获知输注设备的工作状态并进行处理。通过数据处理装置将数据存储为易读文件，便于后续查阅和存档，数据处理装置还连接到HIS，以实现医院大数据的整合。此外，在数据从输注设备到数据处理装置甚至到HIS的传输过程中，采用多层加密，提高了数据传输的安全性。
在上文的实施方式中描述输液监护系统的过程中，显然还公开了一些处理或方法。下文中，在不重复上文中已经讨论的一些细节的情况下给出这些方法的概要，但是应当注意，虽然这些方法在描述输液监护系统的过程中公开，但是这些方法不一定采用所描述的那些部件或不一定由那些部件执行。例如，用于输液监护系统的实施方式可以部分地或完全地使用硬件和/或固件来实现，而下面讨论的方法可以完全由计算机可执行的程序来实现，尽管这些方法也可以采用用于输液监护系统的硬件和/或固件。
根据本申请的一个实施例的一种输液监护方法包括：将执行输液操作的一个或多个输注设备的相关信息发送至中继设备；由中继设备将所述相关信息转发至数据处理装置；由数据处理装置对来自中继设备的数据进行处理。
其中，输注设备的相关信息通过第一通信接口发送给中继设备。第一通信接口例如包括如下之一：串口、通用串行总线接口、无线通信接口。在一个示例中，第一通信接口被配置为禁止接收数据。第一通信接口可以被配置为周期性地发送相关信息。
输注设备的相关信息包括如下至少之一：输注设备的标识、使用输注设备的用户的信息、当前流速、预计输液量、已输液量、药物名称、工作模式、Bolus速度、KVO速度、输注设备的工作状态指示。
例如，输注设备的相关信息在发送给中继设备之前还可以进行加密。
中继设备在转发所接收到的相关信息之前也可以对相关信息进行加密。中继设备可以通过无线或有线的方式向所述数据处理装置发送数据。无线的方式例如包括如下之一：WiFi、蜂窝通信技术、蓝牙。
还可以使中继设备对如下中的至少一个进行显示：输注设备的相关信息、输注设备的当前连接状态、中继设备与数据处理装置的连接方式。
在一个示例中，数据处理装置执行的处理可以包括：从所接收的数据中分离每个输注设备的数据；每个输注设备，基于该输注设备的数据进行显示控制；以及基于显示控制来分别显示各个输注设备的工作状态。
此外，上述处理还可以包括对所接收的数据执行解密操作。
上述处理还可以包括向医院信息化系统发送数据。在一个示例中，在向医院信息化系统发送数据之前还可以先对该数据进行加密。
上述处理还可以包括存储所接收的数据，以用于后续的查阅等目的。
在存在工作状态异常的输注设备时，上述处理还可以包括生成向用户发出提示的提示信号的步骤。显示各个输注设备的工作状态例如可以用不同的颜色以及/或者动画来显示输注设备的不同的工作状态。
