请一并参阅图4，所示为本申请又一实施例中注射泵的结构示意图。推拉 机构114包括连接杆1142及推动块1140，推动块1140固定于连接杆1142的一端，连接杆1142沿自身轴向滑动连接于泵主体110，推拉机构114在驱动机构133的带动来可沿连接杆1142的轴向移动。夹柄机构118可转动设置于泵主体112上，在用户的转动操作下，夹柄机构118可在第一状态与第二状态之间进行切换。在设置注射器60之前，用户可将夹柄机构118由第一状态转动(如图2所示)至第二状态(如图4所示)，并将推拉机构114以远离泵主体110的方向拉出预设长度(如将图2中推拉机构114向右拉出预设长度后推拉机构114位于图4所示的位置)，以使得注射泵10具有足够的空间来设置注射器60。
请一并参阅图5，所示为本申请一实施例中注射器设置于注射泵的示意图。本实施例中，注射器60包括注射器本体602、设置于注射器本体602一端的凸缘604及活塞柄606，其中，注射器本体602内中空，用于收容活塞柄606，活塞柄606可在注射器本体602的径向方向移动。在将注射器60设置于注射泵10内时，用户可转动夹柄机构118至第二状态，以将注射器本体602压装于注射泵的泵主体110上，注射器50的凸缘604收容于泵主体110的收容槽116，活塞柄606与推动块1140之间的距离为预设距离d(示于图6)。
本实施例中，泵门112内可设置有位置传感器164，处理器150通过设置于泵门112内的第一位置传感器确定泵门112的状态，其中，泵门112的状态包括打开状态及关闭状态。如图2所示，处理器150可通过设置于第一位置传感器确定泵门112处于打开状态。请一并参阅图6，所示为本申请一实施例中注射泵的泵门被关闭的状态示意图。如图6所示，处理器150可通过第一位置传感器确定泵门112处于关闭状态。
本实施例中，夹柄机构118内设置有第二位置传感器，在将设置于注射泵10内的注射器60压装于注射泵10的泵主体110上时，夹柄机构118处于第二状态，此时，第二位置传感器可传输反馈信号。因此，处理器150可通过第二位置传感器检测注射器60是否设置于注射泵10内。例如，当注射器60设置于注射泵10内时，夹柄机构118将注射器本体602固定于泵主体110上，且第二位置传感器可输出反馈信号。如此，处理器150可确注射器60的注射器本体602压装于注射泵10的泵主体110上。在其他实施例中，夹柄机构118内可设置有压力传感器，即在注射器60压装于注射泵10的泵主体110上时，压力传感器可与注射器60接触，进而产生具有压力信息的反馈信号。处理器150亦可根据接收到的具有压力信息的反馈信号确定是否将设置于注射泵10内的注射器60压装于注射泵10的泵主体110上。
本实施例中，收容槽116内设置有第三位置传感器。在注射器60设置于注射泵10内时，注射器60的凸缘604收容于收容槽116内，此时，第三位置传感器亦可输出反馈信号。如此，当处理器150接收到第三位置传感器输出的反馈信号时，处理器150可确注射器60的凸缘604收容于收容槽116。
进而，处理器150可根据第一位置传感器检测泵门112的状态，还可根据第二位置传感器及第三位置传感器检测注射器60的设置状态。本实施例中，当第二位置传感器及第三位置传感器均传输反馈信号至处理器150时，处理器150可确定注射器60的设置状态正常；当处理器150没有接收到第二位置传感器及第三位置传感器中任一传感器所传输反馈信号时，处理器150可确定注射器60的设置状态异常。例如，当处理器150接收到第二位置传感器传感器传输的反馈信号而没有接收到第三位置传感器传输的反馈信号时，表示注射器60的凸缘604收容于收容槽116内，进而检测到注射器60的设置状态异常；当处理器150接收到第三位置传感器传感器传输的反馈信号而没有接收到第二位置传感器传输的反馈信号时，表示用户没有转到夹柄机构118至第二状态，夹柄机构118并没有将将注射器本体602固定于泵主体110上，进而处理器150亦可检测到注射器60的设置状态异常。处理器150在确定注射器60的设置状态异常时，控制显示屏160输出注射器60的设置状态异常的提示信息，处理器150还可通过灯光控制器148控制灯光组件168输出注射器60的设置状态异常的提示信息。
在一实施例中，若泵门112处于关闭状态且注射泵10内未设置有注射器60，注射泵10可处于关机状态或待机状态，若用户使用注射泵10来执行注射器60的输注任务，用户需要打开注射泵10的泵门112。在处理器150通过第一位置传感器检测到泵门112被打开时，处理器150控制注射泵10上电或进行开机操作，使得注射泵10处于开机状态。在用户设置注射器60期间(即处理器150检测到泵门112被打开至检测到泵门112被关闭的时间段内)，注射泵10可进行自检操作，以检测注射泵10的设备状态。其中，注射泵10的自检操作包括但不限于声音自检、处理器自检、外部存储装置自检、报警灯自检、电源自检以及传感器自检。在进行声音自检时，处理器150可通过音频电路124控制扬声器154发出声响，并可通过录音装置确定声音自检是否通过；若处理器通过录音装置接收扬声器154发出声响，则可确定声音自检已通过，否则，表示注射泵10的设备状态异常。在进行处理器自检时，处理器150可运行存储器104内预设的程序，并确定运行预设的程序后得到的结果是否为预设结果；若对待预设的程序后得到的结果为预设结果时，则可确定处理器自检已 通过，否则，表示注射泵10的设备状态异常。此外，处理器150亦可对外部存储装置、灯光组件168、电源系统106以及多个传感器进行检测。当每一自检操作均通过时，可确定注射泵10的设备状态正常；在存在至少一个自检操作未通过时，则确定注射泵10的设备状态异常，并可通过显示屏160或灯光组件168输出设备状态异常的提示信息。
由于现有的技术方案可能会在设置注射器60于注射泵10之前执行自检操作，即在注射泵10完成自检操作之后再打开泵门112并将注射器60设置于注射泵10中，进而在一定程度上增加了输注任务准备阶段(或输注操作准备阶段)的时间。本实施例中，在泵门112被打开时，注射泵10进行开机动作，并在设置注射器60于注射泵10的过程中同时执行自检操作，即通过将注射泵10的自检操作与注射器60的设置进行并行处理，有利于减少输注任务准备阶段的时间。
在其他实施例中，注射泵10可包括开机按键(包括但不限于实体按键或其他类型的按键)，在开机按键被触发时，用户可打开泵门112，以将注射器60设置于注射泵10中。之后，注射泵10亦在设置注射器60于注射泵10的过程中同时执行自检操作，亦可达到减少输注任务的时间的目的。
步骤143，在检测到所述泵门被关闭且所述注射器在所述注射泵中的设置状态正常时，控制所述显示屏显示输液参数设置界面。
本实施例中，在处理器150检测到泵门112被关闭且注射器60设置于注射泵10中的设置状态正常，处理器150可控制设置于泵门112上的显示屏160显示输液参数设置界面510，其中，输液参数设置界面510包括输液参数设置项，输液参数设置项用于呈现一个或多个输液参数内容，包括但不限于输液速度、输液量等输液参数内容。当泵门112被关闭且注射器60设置于注射泵10中的设置状态正常时，推拉机构114的推动块1140与活塞柄606之间具有预设距离d，因此，驱动机构133控制推拉机构114启动输注操作时，驱动机构133需要将推动块1140朝向活塞柄606的预设距离d后，使得推动块1140与活塞柄606相抵住(或者相接触)，之后，处理器150再根据设置的输液参数内容进行输注动作(或输注操作)。由于现有的技术方案可能会在推动块1140与活塞柄606相抵住之后，再控制显示屏160显示输液参数设备界面510，而推动块1140移动预设距离与活塞柄606相抵时需要一定的时间，如此，亦会使得输注准备阶段的时间增加。
请一并参阅图7，所示为本申请一实施例中推拉机构抵住活塞柄的状态示意图。本实施例中，在注射器60在注射泵10中的设置状态正常时，处理器150 在控制显示屏160显示输液参数设置界面510的同时，处理器150驱动驱动机构133以第一电机转速动作，带动推进机构114以朝向注射器60的活塞柄606的方向运动，驱动机构133在以第一电机转速动作预设时间后推进机构114抵住606活塞柄。如此，用户在通过输液参数设备界面510进行输液参数设备的同时控制推拉机构114的动作，如此，亦有利于减少输注操作的时间。
步骤145，根据至少一个所述输液参数内容驱动所述驱动机构进行运动，以使所述注射器内的液体按照输液方向移动。
本实施例中，当推进机构114抵住606活塞柄后，注射泵10可进入启动输注操作阶段，处理器150可根据至少一个输液参数内容驱动驱动机构133以第二电机转速运动，控制注射器60的活塞柄606与注射器本体602发生相对运动，以使注射器60内的液体按照输液方向移动。
在本实施例中，泵门112上可设置有多个显示屏160，例如，设置有第一显示屏及第二显示屏，其中，第一显示屏用于显示输液参数设置界面510，第二显示屏用于显示功能操作界面512。如图7所示，功能操作界面512包括进度条显示区518、菜单按键区514及开关按键区516。在驱动机构133驱动推拉机构114进行输注操作时，表示注射泵10正在进行输注操作，此时，处理器150可控制进度条显示区518具有第一颜色信息(如绿色)；在输注操作完成时，处理器150可控制进度条显示区518具有第二颜色信息(如红色)；当注射泵10没有进行输注操作且注射泵10中没有设置注射器60时，处理器150可控制进度条显示区518具有第三颜色信息(如灰色)。
用户可通过触发菜单按键区514来对输液参数设备界面510内的内容进行设置或操作，并可确定是否启动输注操作。例如，用户在输液参数设备界面510进行设置时，处理器150用于检测用户在输液参数设置界面510上的触发事件，并基于所述触发事件调整输液参数内容。在驱动机构133以第一电机转速驱动推拉机构114移动预设距离d后接触活塞柄606时，若用户还在调整输液参数内容，此时，驱动机构133可暂停驱动推拉机构114，并在用户设置完成且启动输注指令后，处理器150再根据输液参数内容驱动驱动机构133进行运动，以启动输注操作。本实施例中，输注指令为用户在设置输液参数内容后触发启动按键时产生的，或者启动输注指令可由Dock发送。例如，在Dock中可能连接有多个注射泵，多个注射泵可用于按顺序执行多个药物的注射操作。Dock可根据多个注射泵的输注操作的顺序来发送启动输注指令至对应的注射泵。在检测到第一位置的注射泵的输注操作完成或即将完成时，Dock可发送启动输注指令至输注操作的顺序位于第一位置后的第二位置的注射泵，进而使得位于第二位 置的注射泵在接收到Dock所发送的启动输注指令后执行启动输注操作。用户可通过触发开关按键区516来完成注射泵10的开机、关机或待机动作。在一实施例中，推动块1140上可设置压力传感器，如此，在推动志1140块住活塞柄606时，设置于推动块1140上的压力传感器可输出具有压力信息的反馈信号至处理器150，进而使得处理器150在确定接收到设置于推动块1140上的压力传感器所传输的反馈信号时，可确定推动块1140与活塞柄606相抵住。如此，处理器150在接收到第二位置传感器、第三位置传感器及设置于推动块1140上的压力传感器所输出的反馈信号时，在用户设置完输液参数内容后接收到启动输注指令时，处理器150可根据设置的输液参数内容来控制驱动机构133的第二电机转速，以继续执行输注操作。
请一并参阅图8，所示为本申请一实施例中注射泵启动输注操作时的示意图。本实施例中，推拉机构114用以夹持注射器60的活塞柄606。注射泵10中的处理器150发出转速或者位置等指令，通过动力驱动电路130驱动动力设备(例如驱动机构133)，驱动机构133经减速机构驱动丝杆135和丝母137，将驱动机构133的旋转运动转化为丝母137的直线运动，丝母137与注射泵10的连接杆1142相连，连接杆1142与推动块1140连接，推动块1140可推动配套的注射器60的活塞柄660进行注射输液，通过驱动机构133的旋转速度(如第二电机转速)，就可调整其对配套的注射器60的推进速度，从而调整所给的输注剂量和输注速度。
在一实施例中，注射泵10在开机时或者是在更换注射器60期间，处理器150可在第一显示屏显示装管指引界面，包括但不限于注射器60的设置方向、设置时需注意的事项等内容，以方便用户准确地进行注射器60的设置。在其他实施例中，处理器150可在检测注射器60在注射泵10中的设置状态被检测为正常时或之前，控制第一显示屏显示装管指引界面。
在一实施例中，泵门112上设置有一个显示屏160，如此，输液参数设置界面510及功能操作界面512可设置于显示屏160的不同分区内。
在一实施例中，在检测泵门112的状态及注射器60在注射泵10中的设置状态之后，处理器150可确定注射器10内液体的预置量信息。例如，处理器150在检测到泵门112被打开至泵门112被关闭的期间确定注射器10内液体的预置量信息。其中，处理器150可通过传感器检测注射器60的外径信息及注射器60内液体在注射器60的活塞柄606的长度方向的长度信息，进而基于外径信息及长度信息确定注射器60内液体的预置量信息。在其他实施例中，用户亦可在输液参数设置界面510内设置预置量信息。
在执行输注操作过程中，注射器60内的液体逐渐减少，进而，处理器150还可根据驱动机构133的动作确定已输注的液体体积信息及注射器60内液体的剩余的液体体积信息。处理器150还可根据剩余的液体体积信息及输液参数内容确定输注进度信息，如确定剩余的输注时间。处理器150还控制显示屏160内显示输注进度信息。
目前注射泵在启动输注之前的准备工作流程中均采用串行设计，开机之后会进行开机自检，并在开机自检成功之后才开始识别注射器状态；用户打开泵门装注射器，会将推拉机构拉开，并等到注射器在注射泵内设置成功，并且推拉机构与活塞柄夹持成功之后，才会在屏幕上设置输液参数设置界面以供用户编辑或者确认。中间仅推拉机构从最远处到与活塞柄夹持的时间就可以能需要数十秒，这个过程十分漫长，且用户只能等待，十分不合理。
上述注射泵控制方法通过将注射泵的自检操作与注射器的设置进行并行处理，有利于减少输注任务的时间的花费。另外，注射泵在检测到泵门被关闭且注射器在注射泵中的设置状态正常，控制显示屏显示输液参数设置界面，如此亦可减少在等待推拉机构运行预设时间后抵住活塞柄后再显示输液参数设置界面所带来的输注时间的浪费的不足。上述注射泵控制方法检测到并可在通过输液参数设备界面进行输液参数进行输入和/或确认的同时控制推拉机构的动作，如此，亦有利于减少输注操作的时间。并且为了确保注射泵的使用安全，只有在推拉机构与活塞柄夹持正确之后，且注射泵的输液参数设置完成之后，用户才能启动输注，既有效缩短了用户的等待时间，并且无损注射泵的使用安全。
