附图说明
图1是本实施例的主要结构框图。
具体实施方式
为了进一步解释本发明的技术方案，下面通过具体实施例来对本发明进行详细阐述。
结合图1所示，是本发明揭示的具有药液输液报警功能的装置，包括电源模块、称重模块、单片机处理模块、药液容器模式选择模块、显示模块和报警模块。称重模块、药液容器模式选择模块、显示模块和报警模块分别与单片机处理模块进行连接。电源模块分别与称重模块、显示模块和单片机处理模块连接并供电，电源模块采用2节1.5V干电池串联并依次通过升压、稳压电路后进行供电。
称重模块用于测量药液容器和与药液容器相连接的输液器的重量。称重模块由称重传感器、信号放大电路和A/D转换电路完成重量检测和信号转化，称重模块上用于分别连接自身称重传感器和药液容器的钩子可以360度转动，以利于放置药液容器。
药液容器模式选择模块根据药液容器的容量和包装方式的不同设置具有不同固定报警重量的模式按钮。药液容器的容量和包装方式为，500ml、250ml、100ml和50ml的玻璃瓶四种，500ml、250ml和100ml的软瓶或软袋三种，以及3000ml的软袋一种，共8种。具有不同固定报警重量的模式按钮分别与上述几种药液容器的容量和包装方式一一对应。
药液容器模式选择模块还具有与模式按钮一一对应的模式发光二极管；药液容器模式选择模块根据药液容器的容量和包装方式设定的固定报警重量，大于药液容器和与药液容器相连接的输液器自身重量的总和，一般设置呈略大于即可。当按下模式按钮时，模式发光二极管点亮。
还包括分别与单片机处理模块和电源模块连接的电机锁定模块，电源模块给电机锁定模块供电。电机锁定模块由单片机处理模块控制，电机锁定模块动作时用于自动夹住输液软管，使输液软管不导通，能实现该功能的装置有很多，本实施例将由电机作为动力来自动夹住输液软管的装置，统一称为电机锁定模块。
单片机处理模块用于将称重模块测量的重量数据和按压的药液容器模式设定的固定报警重量进行比较。
当单片机处理模块检测到称重模块测量的重量数据等于或小于按压的药液容器模式设定的固定报警重量时，即药液即将输完，单片机处理模块控制电机锁定模块夹住软管，阻断输液软管内的液体流动，同时单片机处理模块将报警信号发送至报警模块报警。报警模块报警即可提醒护理人员查看，以便于护理人员及时通知医护人员更换药液或拔针，避免病人的血液自针孔回流至输液管，消除病患者不必要的疼痛和安全隐患，也可以使护理人员更好地休息，降低护理人员的护理强度。
当单片机处理模块检测到称重模块测量的重量数据大于设定的固定报警重量，且在单片机处理模块预设的时间段内无变化时，即针头紧贴血管壁造成的输液药液不能进入血管或者其他原因导致输液受阻时，单片机处理模块将报警信号发送至报警模块报警。报警模块报警即可提醒护理人员查看，以便通知医护人员发现问题所在。
当单片机处理模块检测到称重模块测量的重量数据为零时，即本装置未使用时，单片机处理模块进行计时，当计时的时间超过单片机处理模块预设定的时间时，控制具有药液输液报警功能的本装置自动关机。
单片机处理模块还根据称重模块检测的重量变化计算出药液输液的平均速度和药液输液完毕的剩余时间，并在显示模块上显示该药液输液的平均速度和药液输液完毕的剩余时间，以便护理人员或医护人员查看。
其中报警模块包括分别与单片机处理模块连接的蜂鸣器、报警发光二极管和复位按钮，报警模块可分别发出声音和光报警信号。复位按钮用于复位具有药液输液报警功能的本装置，即按下复位按钮时，可中断蜂鸣器和报警发光二极管的报警，同时使夹住输液软管的电机锁定模块松开。在护理人员或医护人员处理后，即可按下该复位按钮，恢复正常输液。
还包括分别与单片机处理模块和电源模块连接的蓝牙模块，蓝牙模块与终端设备连接，终端设备安装有APP。APP可发送控制单片机处理模块控制指令，通过APP和蓝牙模块可向单片机处理模块发送复位指令，以中断报警模块的蜂鸣器和报警发光二极管的警报，并使夹住输液软管的电机锁定模块松开;同时可发送指令来改变单片机处理模块发送的报警信号的大小和路数，以调整报警模块的声音大小和报警方式（声音、发光、声音加发光的报警方式）。
蓝牙模块还用于将称重得到的重量数据、药液输液的平均速度、药液输液完毕的剩余时间和报警信号发送到该APP并显示。
APP收到报警信号时控制终端设备发出提醒，以即使提醒监控终端设备的医护人员。还可通过该APP来改变终端设备发出提醒的方式，比如可选择声音或光中的一种以上，当终端设备为手持设备时，还可添加震动提醒的选项。
以上仅为本发明的较佳实施例，并非对本发明的保护范围的限定。凡依本案的设计思路所做的等同变化，均落入本案的保护范围。
