文本输入模块190提供用于在一个或者多个应用程序中输入文本的各种软件部件。具 体的，可以用来输入各种输注参数，包括药品名称、输液速度或者报警阈值等。
在一些实施例中，存储器104存储设备/全局内部状态192。设备/全局内部状态157包括以下中的一者或多者：活动应用程序状态，其指示哪些应用程序(如果有的话)当前是活动的；显示状态，其指示什么应用程序、视图或其它信息占据显示器系统112的各个区域；传感器状态，包括从设备的各个传感器和其他输入或控制设备116获取的信息；以及关于设备的位置和/或姿态的位置和/或方位信息。
在一些实施例中，存储器104(图1A中)存储至少一个应用194，该应用194可以包括输液模式设备194－1、阻塞压力等级设置194－2、气泡等级设置194－3、药物设置194－4、音量设置194－5、亮度设置194－6、联机设置195－7、Dock设置195－8或者温度设置195－9。其中输液模式设备194－1可以包括预设输注参数的组合，以适应不同使用场景的需求；其中阻塞压力等级设置194－2可以包括提供用户输入不同的阻塞压力等级的接口，通过输入不同的阻塞压力可以调整输注泵100的阻塞报警阈值，以适应不同使用场景的需求。其中气泡等级设置194－3可以包括提供用户输入不同的气泡等级的接口，通过输入不同的气泡等级可以调整输注泵100的气泡报警阈值，以适应不同使用场景的需求。其中药物设置194－4可以包括提供用户输入不同药品名称、药品简称和/或药品颜色的接口等，通过输入相应的药品名称/简称/颜色等进行输液前的药物参数设置，以便于在输注过程中，输注泵100内部的自动确认或者医护人员的核对。其中音量设置194－5提供了用户根据需求调整报警音量和/或其他音频输出的音量大小。其中亮度设置194－6提供了用户根据需求调整屏幕亮度、报警灯、照明灯等亮度大小。其中联机设置195－7提供了用户根据需求控制输注泵100与其他设备是否进行联机工作，联机工作模式等输入接口。其中Dock设置195－8提供了用户根据需求调整与输注泵100相连接的安装座(Dock)的工作参数的设置接口。其中温度设备195－9提供了用户对加热输液器内液体温度的设置接口。
现有输注泵100在进行输注操作时，其参数配置、开关机以及启动或暂停驱动的动作可以通过触摸屏一个控件即全部实现。同时触摸屏还能显示各传感器实时采集到的监控参数，用于反映输注泵100的工作状态。可以理解的，若输注泵100出现工作异常时，触摸屏还能实时对用户发出提示和报警。因此，触摸屏丰富的交互功能可以减少输注泵100上额外设置按钮的必要性，进而提升输注泵100的外观一致性。
但触摸屏的外表面多为玻璃或塑料材质，长期使用过程中存在易损坏的缺陷。损坏的触摸屏可能出现触摸功能失灵，或触摸屏无法显示等现象。若在患者输液过程中出现突发事件需要暂停中止输液，而触摸屏无法工作时，会对患者造成较大的安全隐患。
为此，请参见图2所示的实施例，本申请第四方面涉及的输注泵100至少包括处理器150、I/O接口(设于输入/输出系统108)、触摸屏(设于显示器系统160)、显示控制器140、驱动机构(通过动力驱动电路130连接至处理器150)、输出接口(设于外部端口122)以及至少一个传感器。驱动机构受动力驱动电路130控制并用于驱动输注泵100的输注动作。I/O接口与设置于输注泵100上的按钮连接。至少一个传感器可以包括滴数传感器132、气泡传感器134、压力传感器136、温度传感器138中的至少一者。
请同步参见图3，本申请输注泵100的处理器150可配置用于执行本申请第一方面提供的输注泵的中止控制方法，具体包括如下步骤：
S10、检测到输液参数设置事件或者调用默认输液参数；
具体的，输注泵100在启动输液动作之前，需要先对其输液参数进行设置，或调用默认的输液参数，以确定输注泵100当前进行输液操作的药物名称、流速数值、流速单位、输液模式、耗材、剩余量和剩余时间等相关参数。
S20、检测到输液启动事件，则发送启动驱动指令以使驱动机构工作；
具体的，当输注泵100的参数确定之后，医护人员可以通过在触摸屏等控件上执行预设的操作，也可以是控制输液启动硬按键来触发输液启动事件，使得处理器150发送启动驱动指令，使得驱动机构执行步骤S10中设置的输液动作。
S30、在驱动机构工作的期间，接收输注泵100的多个传感器的反馈信号，并检测到I/O接口的预设的电信号变化和检测到显示控制器140中所发送的中止指令的任意一个；响应预设电信号和中止指令的任意一个，发送停止驱动指令以使驱动机构停止工作；
具体的，在驱动机构工作期间，处理器150还实时接收各个传感器的反馈信号，用于监测输注泵100的工作过程状态。传感器可以包括滴数传感器132、气泡传感器134、压力传感器136和温度传感器138中的至少一者，其中压力传感器136可用于监测输液器是否出现阻塞。处理器150还用于基于接收到的反馈信号确定输注泵100是否进入报警状态，并通过输出接口向用户发送提示信息。例如当压力传感器136监测到压力异常时，其发送给处理器150的反馈信号超出预设阈值范围，处理器150基于该超出预设阈值范围的反馈信号确定输液器出现阻塞而进入报警状态，处理器150通过输出接口向用户发出对应阻塞报警信息的提示信息。
用户接到该提示信息后，需要中止输注泵100的输液动作，以对异常状态进行排查，避免输注泵100在异常状态下持续对患者进行输液操作而可能造成的安全隐患。而本申请输注泵100提供了两种控制方式来触发处理器150发送停止驱动指令以使驱动机构停止工作：一种控制方式为通过操作与I/O接口连接的按钮，使得按钮发出预设的电信号；另一种控制方式为通过操作触摸屏，使得显示控制器140发出中止指令。处理器150在接到两种控制方式中的任意一种时，都会响应并向驱动机构发出停止驱动指令。当然，也可以是根据医嘱的变化，来执行中止输注泵100的输液动作，也可以按照上述方式进行操作。
可以理解的，输注泵100的触摸屏和按钮通常是分开设置的，即本申请输注泵100在执行输液动作的过程中，可以提供两个分别独立的控件以应对报警状态下的中止驱动动作。其中用户通过对触摸屏进行操作以触发显示控制器140发出的中止指令，与用户通过对触摸屏进行操作以触发其余控制指令一样，相对符合用户的使用习惯，可以作为常规的中止驱动的控制方式存在。而基于前述中提到的原因，触摸屏相对易损，其长期使用后出现变形也容易造成触控电极失效、线路老化接触不良等现象。因此，用户还可以基于注射泵100的报警状态，通过按钮发出预设的电信号变化来控制输注泵100中止驱动。按钮通过I/O接口向处理器150发送预设的电信号变化相对可靠性较高，且易于操作，对于触摸屏的控制方式能够形成有效的补充，提升本申请输注泵100的安全性，消除了因为触摸屏失效而可能造成的安全隐患。
S40、在驱动机构停止工作的期间，确定输注泵100的设备报警状态并通过输出接口发送提示信息，其中提示信息包括电路电压异常报警、通信异常报警、低电量报警和电池异 常报警中的至少一个。
具体的，在处理器发出停止驱动指令以控制驱动机构停止工作之后，输注泵100并不需要基于停止驱动指令停止其全部工作，而是只需要中止其与输液动作相关的操作以及监测工作即可。而与输注泵100的电能、通信等相关的参数监测，依然可以持续进行。以保证输注泵100能维持基本的工作状态，并在后续故障排除之后迅速重新启动驱动输液的动作，提高工作效率。
当输注泵100在驱动机构停止工作期间出现影响其重新启动驱动输液动作的异常，如电压异常波动、心跳包接收异常、电池电量过低等情况时，输注泵100可以通过输出接口发送对应该异常状态的提示信息，以供用户对应解除异常状态。可以理解的，此时输注泵100还可以保持触摸屏的显示功能，并持续提供各传感器的监测结果供用户观测。
一种实施例请参见图4，在步骤S30中，处理器150检测到的信号为显示控制器140中所发送的中止指令，且在检测到该中止指令之前，还包括：
S35、检测到用户基于触摸屏的预设第一区域上的操作事件；
S36、响应操作事件并触发中止指令。
具体的，触摸屏上预设第一区域可以定义为图像模块182在触摸屏上渲染的图形，该图形对应触发中止指令。而触控模块174可以结合显示控制器140检测到用户对该图形(即第一区域)的操作事件。操作事件可以为简单的手指接触、按压、划动以及双击等任意事件。只要用户在触摸屏的预设第一区域上进行了对应的操作事件输入，都可以触发显示控制器140向处理器150发送中止指令以停止驱动输液的动作。
一种实施例，在步骤S30驱动机构工作的期间，还包括：
S30a、接收输注泵100的多个传感器的反馈信号；根据反馈信号，确定输注泵100的工作状态异常并通过输出接口自动发送停止驱动指令以使驱动机构停止工作。
具体的，本实施例相对于步骤S30可以作为并行的控制步骤展开。在驱动机构工作执行输液动作期间，处理器150还可以基于传感器的反馈信号差异，确定到输注泵100的工作状态异常程度。当输注泵100的工作状态异常超出预设阈值范围时，直接自动发送停止驱动指令以中止驱动机构的工作，无需再接用户通过触摸屏或按钮发送的中止指令或检测到预设的电信号。
可以理解的，本申请输注泵中止控制方法在本实施例中，处理器150通过各传感器的监测，能够对反馈信号形成差异响应的能力。对于步骤S30a中触发自动发送停止驱动指令的反馈信号阈值范围，大于步骤S30中触发提示信息的反馈信号阈值范围。即在反馈信号显示输注泵100的工作异常状态相对轻微时，处理器150可以通过提示信息来供用户判断是否需要中止驱动输液的操作；而在反馈信号显示输注泵100的工作异常状态相对严重时，处理器150直接自动发送停止驱动指令以中止驱动机构的工作。
一种实施例，在步骤S30或S30a中，当驱动机构在工作期间因为处理器150响应预设电信号或中止指令而被停止了驱动动作，本方法还包括：
S38、驱动机构停止工作的同时改变触摸屏的预设第一区域的触摸事件定义，使预设第一区域的触摸事件定义由中止指令变成启动指令；检测到用户基于触摸屏的预设第一区域的操作事件；响应操作事件并触发启动指令；根据启动指令发送启动驱动指令，以使驱动 机构工作。
具体的，在处理器150发出停止驱动指令之后，驱动机构已经停止了输液动作。而此时触摸屏的第一区域如果继续显示为对应中止指令的图形，且基于检测到的用户对于第一区域的操作事件而发送中止指令给处理器150，已经失去作用。因此需要在处理器150发出停止驱动指令的同时，改变触摸屏的第一区域的定义，使其从中止指令切换为启动指令。后续在检测到用户对第一区域的操作事件后，处理器150可以响应该操作事件发送启动驱动指令给驱动机构，并恢复输注泵100的输液工作。
可以理解的，触摸屏上预设的第一区域的定义改变，需要在处理器150发送停止驱动指令的同时执行，以保证驱动机构在停止工作后触摸屏上能出现对应启动驱动机构再次工作的控件区域。且将对应触发中止指令的第一区域切换定义，使其成为触发启动指令的控件区域，用户在触摸屏的同一区域上输入操作事件以对应驱动机构的中止和启动，符合用户的使用习惯。同时，因为驱动机构在停止工作的情况下再触发中止指令已经失去意义，因此将两个相互对立的控制指令设置于触摸屏的同一控件区域上，还无需改变触摸屏其它显示区域或触控区域的布局，保证触摸屏显示功能的延续性。
另一方面，在处理器150响应操作事件发送启动驱动指令给驱动机构恢复输注泵100的输液工作的同时，还可以再次改变触摸屏第一区域的定义，使其从启动指令切换为中止指令，并在此后响应用户的操作事件发送停止驱动指令给驱动机构。
一种实施例，在步骤S30中，检测到显示控制器140中的所发送的中止指令之前，还包括：
S33、检测到显示控制器140所发送的解锁屏幕的指令。
具体的，触摸屏通常为了防止误操作的发生，会在输入控制指令之前设置屏幕解锁的步骤。当用户对应输入解锁屏幕的操作事件之后，才能完成中止指令等控制指令的输入。对于输注泵100而言，中止指令的误操作可能带来较为严重的后果，因此本申请输注泵的中止控制方法对触摸屏触发的中止指令还引入了解锁屏幕的指令来提高其安全性。
一种实施例请参见图5，在步骤S33“检测到显示控制器140所发送的解锁屏幕的指令”中，还包括如下子步骤：
S331、检测到用户基于触摸屏的预设第二区域上的操作事件；
S332、响应所述操作事件并触发解锁屏幕的指令；
S333、检测到显示控制器140所发送的解锁屏幕的指令；
具体的，解锁屏幕的指令也可以通过对触摸屏的操作来完成。用户需要在触摸屏上区别于第一区域的第二区域上执行对应解锁屏幕指令的操作事件，以使得触摸屏相应该操作时间并触发解锁屏幕的指令，最后由显示控制器140将解锁屏幕的指令发送给处理器150。然后，用户才能在第一区域上执行操作时间并触发中止指令。
为了便于用户的操作，还可以将触摸屏上预设第二区域与预设第一区域设置在触摸屏的同一个象限或者相邻象限位置，即第二区域和第一区域相邻设置，以便于用户在解锁屏幕之后能够快速的中止驱动机构的工作。可以理解的，当触摸屏按几何关系分为四个不同的象限之后，设置于同一象限内的两个区域相对位置更近。或分别设置于相邻两个象限内的两个区域也具有相对靠近的距离。因此设置第一区域和第二区域在触摸屏的同一象限或 相邻象限的位置，便于用户通过连续的操作输入来解锁触摸屏并触发中止指令。
一种实施例请参见图6，对应到图4的实施例不同，图6的实施例中步骤S30处理器150检测到的信号为I/O接口中预设的电信号，且在检测到该预设的电信号变化时，还包括：
S35b、检测到I/O接口的预设的电信号变化，且未检测到显示控制器140所发送的解锁屏幕的指令。
具体的，前述中提到，连接至按钮的I/O接口所触发的预设电信号变化，通常作为触摸屏发送中止指令的辅助措施使用。通常在触摸屏损坏或无法响应输入操作的时候才使用按钮来触发停止驱动指令，使其形成一种应急保护机制。因此，连接至按钮的I/O接口因为与触摸屏的控制方式相互独立，其并不需要在处理器150接收到解锁屏幕的指令之后，才能触发停止驱动指令。且因为及时中止驱动机构的工作对保障患者的安全性尤为重要，因此定义处理器150在通过检测到I/O接口的预设电信号而发送停止驱动指令时，无需再通过解锁触摸屏即可实现。
一种实施例，在步骤S30检测到I/O接口的预设的电信号变化时，还包括：
S33b、在预设时间段内，检测到I/O接口的多个电信号变化拐点；或者
在预设时间内，检测到I/O接口的持续的预设电信号。
具体的，连接按钮的I/O接口实际通常只产生高电平和低电平两种电信号。且按钮未按下时，I/O接口处通常处于低电信号的状态。只有在按钮被按下时，I/O接口处的电平才会置为高电平，并形成电信号从低到高的变化拐点。在本实施例中，通过在预设时段内检测到I/O接口的多个电信号变化拐点，可以理解为在预设时段内I/O接口的电信号多次在高电平与低电平之间切换。即用户需要在预设时段内连续按下按钮，才能实现该预设电信号变化的输入；而对于预设时段内检测到I/O接口的持续预设电信号，可以理解为在预设时段内用户对按钮进行了长按的操作，使得预设时段内的电信号持续为高电平。
这样，对应到通过按钮进行预设电信号的输入操作以触发停止驱动指令的控制方式，可以为预设时段内用户的长按操作，或预设时段内用户的双击或双击以上的连击操作，才能触发I/O接口处预设的电信号变化。这样的设置与触摸屏控制方式中的解锁屏幕指令类似，同样可以起到防止按钮被误操作进而误触发停止驱动指令的现象，保证输注泵100的安全性和可靠性。
一种实施例，在步骤S30检测到I/O接口的预设的电信号变化时，还包括：
S34b、检测到I/O接口的特定电信号，若特定电信号的持续时间超过预设时间阈值，则通过输出接口输出按钮失效的提示信息。
具体的，步骤S34b与步骤S33b可以为相互并行的步骤。本实施例中特定电信号变化可以对应到上一实施例中高电平和低电平之外的电信号变化来定义。即按钮在被误操作，或因为接触不良、卡滞等异常情况时，会使得I/O接口产生相应的特定电信号，且该特定电信号区别于按钮正常按下时产生的高电信号，并同时区别于按钮未被按下时产生的低电信号。特定电信号的出现意味着按钮或I/O接口处出现了异常现象，该异常现象如果是因为误操作产生，则只会短暂出现而无法持续产生。但如果异常现象持续一定时长，在本实施例中表现为超过预设时间阈值之后，则可以判断到形成该特定电信号的原因可能为接触 不良或按钮出现卡滞。此时，处理器150同样可以通过输出接口对用户发出按钮失效的提示信息，提醒用户对该异常现象进行排查。
一种实施例，本申请输注泵100还可以包括用于发出提示信息的报警灯，该报警灯可以设置于按钮内，处理器150通过输出接口与报警灯连接并控制报警灯的工作。在步骤S30或步骤S40中通过输出接口发送提示信息时，包括：
S32b、通过输出接口向报警灯发送报警指令；报警灯接报警指令后点亮以发送提示信息。
具体的，报警灯设置于按钮内，按钮为可透光材料制备。当处理器150要通过点亮报警灯来发出提示信息时，报警灯的灯光可以对用户产生视觉提示。进一步的，处理器150还可以通过控制报警灯闪烁来发送提示信息，更利于用户对提示信息的接收。在步骤S30中发出的提示信息通常为监测输注泵100工作过程状态的提示信息，当输注泵100的工作出现异常时，往往需要停止驱动机构的输液动作并进行排查。而将报警灯设置于对应触发停止驱动指令的按钮内，可以在对用户发出提示信息的同时，提醒用户按钮的位置。用户在看到该提示信息之后，还可以通过直接按下点亮报警灯按钮来触发预设的电信号变化，更贴合用户的使用习惯。
一种实施例，输注泵100通常还包括有电源控件(设于显示器系统160或设置为电源按钮)以及与电源控件连接的指令接口(显示控制器140或输入输出系统108)，指令接口响应于电源控件的操作事件并传递关机指令用于切断输注泵100的电源并停止输注泵的工作。此时输注泵100的工作停止包括其驱动机构停止驱动，以及触摸屏、传感器等均断电并停止工作。因此，在步骤S30中驱动机构工作的期间，本申请输注泵中止控制方法还包括：
S31、屏蔽指令接口传递的关机指令。
具体的，电源控件对输注泵100的电源切断，会导致输注泵100突然停止驱动输液的动作，且输注泵100中所有用于监测工作过程状态的传感器全部停止工作。如果在驱动机构工作期间突然切断电源，一方面输液动作暂停可能危害到患者的安全，另一方面由于缺乏后续的参数监控保护，也可能造成更大的安全隐患。因此，在驱动机构工作期间，即输注泵100在输液的过程中，对指令接口进行屏蔽以避免触发关机指令至处理器150，可以避免上述现象的发生，提高输注泵100的安全性。
一种实施例，在本申请输注泵中止控制方法的步骤S40中，当驱动机构停止工作的期间，还包括：
S41、显示输注暂停的显示界面，其中输注暂停的显示界面包括至少一个输液参数设置项的图像，所述输液参数设置项包括药物名称设置项、流速数值设置项、流速单位设置项、输液模式设置项、耗材设置项、待入量设置项和剩余时间设置项中的至少两个。
具体的，在驱动机构停止工作期间，触摸屏向用户展示输注暂停的显示界面。因为驱动机构是在输注泵100出现异常状态时停止的驱动动作，因此医护人员通常需要对输液参数进行调整，以消除该异常状态。需要进行调整的输液参数可以包括更正药物名称、调整流速、调整流速单位、切换输液模式、设置耗材、设置待入量以及设置时间等事项。为了便于医护人员快速完成参数调整，在触摸屏显示的输注暂停显示界面中，至少对应展示上 述参数调整中的两个选项，以便医务人员在暂停界面中直接完成参数调整的操作，可以提高输注泵100的工作效率。
需要提出的是，图4和图6中一些实施例的步骤，如步骤S31“屏蔽指令接口传递的关机指令”和步骤S41中关于输液参数设置的相关内容，并不局限于处理器150接收到的触发停止驱动指令来自于哪一种控制方式。即图6中的部分实施例可以应用于显示控制器140发出中止指令触发处理器发出停止驱动指令的控制方式中，或图4中的部分实施例也可以应用于I/O接口传来预设电信号变化的控制方式中，图4和图6仅作为其中一种实施方式的展示用，并对本控制方法各个实施例步骤的应用范围做限定。
一种实施例请参见图7，本申请输注泵100的处理器150还包括有第一处理器151和第二处理器152，其中第一处理器151通过I/O接口连接至按钮，第二处理器152通过显示控制器140连接至触摸屏。因此，在本方法步骤S30中，还可以包括如下步骤：
S30c、检测到I/O接口的预设的电信号变化；第一处理器1响51应预设电信号并发送停止驱动指令以使驱动机构停止工作；或
检测到显示控制器140所发送的中止指令；第二处理器152响应中止指令并发送停止驱动指令以使驱动机构停止工作。
具体的，本实施例中两种控制方式的控制通路被进一步划分开来。相较于上述实施例中按钮和触摸屏均通过同一处理器150连接至驱动机构形成的控制通路，本实施例中将处理器150进行了划分，分为第一处理器151和第二处理器152。其中按钮通过第一处理器151连接至驱动机构形成一组控制通路，触摸屏通过第二处理器152连接至驱动机构形成另一组控制通路。这样的设置可以避免单一处理器150出现故障或接触不良时，无法顺利发送停止驱动指令到驱动机构的缺陷，进一步提升本申请输注泵100的安全性。
本申请第二方面提供的一种输注泵的中止控制方法请参见图8，同样应用于输注泵驱动配套的输液器输液。在本实施例中输注泵至少包括处理器、触摸屏、与触摸屏连接的触摸屏控制器、I/O接口、驱动机构、输出接口和多个传感器，I/O接口与按钮连接；所述方法包括：
S101、检测到输液参数设置事件或者调用默认输液参数；
S102、检测到输液启动事件，则发送启动驱动指令以使驱动机构工作；
S103、在驱动机构工作的期间，检测到并响应I/O接口的预设电信号变化，发送停止驱动指令以使驱动机构停止工作，并且改变触摸屏的预设第一区域的触摸事件定义，使预设第一区域的触摸事件定义由中止指令变成启动指令。
可以看到，在本申请另一实施例提供的控制方法中，当通过I/O接口触发处理器发送停止驱动指令给驱动机构之后，驱动机构停止输液动作。而此时触摸屏第一区域的定义如果继续设置为对应触发中止指令，则用户对第一区域的操作事件已经失去意义。为此，需要在输注泵通过I/O接口触发处理器发送停止驱动指令给驱动机构的同时，将触摸屏的预设第一区域的操作事件切换为启动驱动指令，便于后续需要重新输液时能快速启动驱动机构。
图9示意了本申请第三方面提供的再一种输注泵的中止控制方法，并对应图10所示的本申请第五方面提供的输注泵100a一并解释。输注泵100a至少包括处理器、第一I/O接 口和第二I/O接口(均设于输入/输出系统108)、驱动机构(通过动力驱动电路130连接至处理器150)、输出接口(设于外部端口122)和至少一个传感器。输注泵100a还包括第一按钮和第二按钮，其中第一I/O接口和第一按钮连接，第二I/O接口与第二按钮连接。本实施例输注泵中止控制方法包括：
S201、检测到输液参数设置事件或者调用默认输液参数；
S202、检测到输液启动事件，则发送启动驱动指令以使驱动机构工作；
S203、在驱动机构工作的期间，接收输注泵的多个传感器的反馈信号；根据反馈信号，确定输注泵的报警状态并通过输出接口发送提示信息，其中提示信息包括堵塞报警信息；检测到第一I/O接口或第二I/O接口中任意一个的预设的电信号变化；响应预设电信号变化，发送停止驱动指令以使驱动机构停止工作；
S204、在驱动机构停止工作的期间，确定输注泵的设备报警状态并通过输出接口发送提示信息，其中提示信息包括电路电压异常报警、通信异常报警、低电量报警和电池异常报警中的至少一个。
具体的，本实施例中的控制方法是基于输注泵100a设有两个独立的按钮，且两个独立的按钮均可用于触发处理器150发送停止驱动指令给驱动机构以停止输液动作的场景。区别于本申请第一方面和第二方面提供的控制方法所对应的输注泵100通过按钮和触摸屏两种控制方式触发停止驱动指令的情况，本申请通过两个独立的按钮设置，省去了触摸屏的设置，可以缩减输注泵100a的成本，并同样满足提高输注泵100a的安全性。且因为按钮组件相较于触摸屏组件具有更高可靠性，因此设置两个按钮的输注泵100a也具备了更高的可靠性。可以理解的，在本实施例提供的输注泵100a中，同样可以设置触摸屏或显示屏，用于提供用户显示反馈以及控制指令的输入等功能。但对于触发停止驱动指令的操作，则不再设置于易损的触摸屏上，进而提高输注泵100a的安全性。
需要提出的是，对于本申请第二、第三方面所提供的输注泵中止控制方法，以及本申请第四方面和第五方面提供的输注泵中各实施例的展开，都可以配合本申请第一方面所提供的输注泵中止控制方法来执行，以进一步提高输注泵的安全性和可靠性，而本申请第六方面和第七方面提供的控制方法和输注泵，也与上述控制方法和输注泵的原理类似，本申请在此不再一一赘述。
另外，对于本申请第四方面提供的输注泵100，其处理器150被配置用于实现上述各实施例的输注泵中止控制方法之外，还可以包括如下的实施例：显示控制器140响应于触摸屏上预设的第一区域上的操作事件以发出中止指令。预设第一区域与按钮的位置属于输注泵100正面的同一象限或者相邻象限。
可以理解的，与上述定义第一区域与第二区域位于触摸屏的同一象限或相邻象限的理由类似，对于按钮和触摸屏上第一区域的设置，宜将按钮设置于触摸屏的外围，且位置与第一区域相邻，以便于用户暂停输液动作时的操作输入。第一区域与按钮之间的距离较近，可以方便用户在未能通过触摸屏的操作成功触发中止指令时，能够快速切换至按钮处进行预设电信号的输入操作；或反之，在按钮处未能成功触发预设电信号时，能够快速切换至触摸屏进行触发中止指令的输入操作。
一种实施例，按钮和第一区域上还同时设有标识部，标识部用于展示按钮和第一区域 之间的映射关系。因为按钮和第一区域都用于触发处理器150的停止驱动指令，因此二者之间因为功能相同而形成了映射关系。在二者之间设置可以展示其相对映射关系的标识部，有助于用户通过对标识部的识别，迅速在触摸屏显示的多个控制区域中找到与按钮对应的用于触发中止指令的第一区域，或迅速在多个按钮中找到与第一区域对应的用于触发预设电信号变化的按钮。在应对突发情况需要紧急停止输液动作时具有更好的指引效果。
对于标识部的具体构造，因为按钮多为实体结构，因此可以将设置于按钮上的标识部构造为区别于按钮本体的凸起、凹槽、图形以及颜色中的至少一者，或二者以上的组合。标识部宜设置于按钮朝向用户的外表面上以便于用户快速识别，只要标识部区别于按钮本体，无论是具有具体结构的凸起或凹槽，还是仅通过按钮外表面形成区别的图像和颜色，都可以被用户快速识别到。而对于设置于第一区域上的标识部，因为不能设置特定的凸起或凹槽，因此只能通过区别于第一区域的背景的图像或颜色中的至少一者来实现。可以理解的，标识部需要具有统一的形状或颜色，以展示按钮和第一区域的映射关系，便于用户快速识别。
以上所述的实施方式，并不构成对该技术方案保护范围的限定。任何在上述实施方式的精神和原则之内所作的修改、等同替换和改进等，均应包含在该技术方案的保护范围之内。
