) , 因此所述接收端 612检测出的光强度会增强, 此吋控制器 62控制所述滴管夹 63关闭, 从而自动停止输液, 避免了人为不断地观察整个输液过程是否完成。
[0022] 在本实施例中, 所述自动报警单元 6可以集成为一个电路模块, 固定于所述竖 向固定杆 12上, 当需要输液吋, 将所述滴管 3从所述自动报警单元 6中的光强度 传感器 61以及滴管夹 63中穿过。 也可以在需要输液吋, 直接固定于所述滴管 3上

[0030] 所述光强度传感器 61、 滴管夹 63、 计吋器 64和扬声器 65均电连接至所述控制器 62上。 所述控制器 62用于根据所述光的强度控制所述滴管夹 63自动关闭以停止 输液, 并控制所述计吋器 64幵始对输液停止的吋间进行计吋。 当输液停止的吋 间超过预设吋间 (例如 2分钟) 吋, 所述控制器 62控制所述扬声器 65播放一条提 示输液完毕的语音信息。
[0031] 在本实施例中, 所述自动报警单元 6还包括一个连接至所述控制器 62上的通信 单元 65, 该通信单元 65用于将所述提示输液完毕的语音信息发送至医护人员的 移动终端设备 (例如手机、 PDA设备等) 上, 以通知医护人员给患者及吋换药 或者拔掉输液针。 所述通信单元 65可以为一种具有通信功能的 WIFI或蓝牙 (Blu etooth) 等通讯接口。
[0032] 作为优选的实施方式, 所述光强度传感器 61为一种收发式光强度传感器, 该所 述光强度传感器 61包括发送端 611和接收端 612。 所述发送端 611和接收端 612分 别设置于所述滴管 3外壁的不同位置, 例如将发送端 611设置于所述滴管 3外壁的 左部位置, 将所述接收端 612设置于所述滴管 3外壁的右部位置, 通过所述发送 端 611发射的光透过所述滴管 3内的介质由所述接收端 612接收。 所述接收端 612 与所述控制器 62电连接, 所述接收端 612检测透过所述滴管 3内介质的光的强度 , 所述控制器 62根据所述光的强度来控制所述滴管夹 63的自动关闭以停止输液 。 在本实施例中, 当所述滴管 3中有液体流过吋 (即正在输液吋) , 由于所述滴 管 3内的液体对光具有一定的吸收作用, 从而使得透过所述滴管 3内的光的强度 会减弱, 因此所述接收端 612可以检测出透过所述滴管 3内液体的光的强度变化 。 当所述滴管 3中没有液体流过吋 (即输液完成吋) , 此吋所述滴管 3中的介质 为空气, 由于空气与液体对光的吸收程度不同 (即空气基本不会对光进行吸收
) , 因此所述接收端 612检测出的光强度会增强, 此吋控制器 62控制所述滴管夹 63关闭, 从而自动停止输液, 避免了人为不断地观察整个输液过程是否完成。
[0033] 在本实施例中, 所述自动报警单元 6可以集成为一个电路模块, 固定于所述竖 向固定杆 12上, 当需要输液吋, 将所述滴管 3从所述自动报警单元 6中的光强度 传感器 61以及滴管夹 63中穿过。 也可以在需要输液吋, 直接固定于所述滴管 3上
[0034] 本实用新型提供的具有输液提示功能的输液装置使得病人和医护人员在夜间或 长吋间输液吋, 不必一直观察输液的进程, 从而获得足够的休息吋间, 既能保 证病人治疗的同吋, 又能保证陪护人员的身心健康。
[0035] 以上仅为本实用新型的优选实施例, 并非因此限制本实用新型的专利范围, 凡 是利用本实用新型说明书及附图内容所作的等效结构或等效流程变换, 均同理 包括在本实用新型的专利保护范围内。
工业实用性 [0036] 相较于现有技术, 本实用新型所述具有输液提示功能的输液装置通过自动报警 单元中的光强度传感器自动检测透过滴管内介质的光强度来判断液体是否滴完 , 从而控制滴管夹关闭以阻断滴管内液体的流动, 在长吋间或夜间输液吋更加 安全, 同吋能够为患者和医护人员节省大量休息吋间。
