多路点滴速度控制与显示装置设计论文--能自动检测输液液位，并将各床位液位和输液速度信号传送至护办室，在护办室对多个病房各个床位的输液情况进行巡回检测和显示。当液位低于设定下限值，输液速度过高或过低，在护办室和相应床位处发出声光报警，提醒护理人员及时处理，采用一种变介电常数型电容式液位传感器。-multi-bit rate control and display design thesis-- can automatically detect infusion. and the Level beds and infusion speed signal transmission to run for room, Office Room in the care of a number of places in various wards infusion of roving detection and display. When the liquid level below the lower limit set, infusion rate is too high or too low, the Office for rooms and beds corresponding issued sound and light alarm, remind nurses handled in a timely manner, using a variable-capacitor dielectric constant liquid level sensor.
