基于单片机的一种便携式输液监控系统

本系统使用STC89C51单片机为主控芯片,以非接触电容式液位检测传感器为检测元件,以LC12S型串口无线收发模块为信号传输装置,用以实现将住院楼患者的输液信息进行多点采集、统一管理,当输液将结束时,报警信号通过无线传输到护士台,对于条件一般的医院中控系统会根据检测结果实现声光报警,并显示具体的报警位置;对于条件较好的医院可以让每一个值班护士配备一个报警手环,手环上可以显示和报警需要更换液滴的病床ID。这样不但降低了医疗事故几率,也提高了医护效率。

This system uses the Single Chip Micyoco(STC89 C51) as the main control chip, uses the capacitance sensor of the liquid level measurement as the detecting element, and uses the port wireless receiving and dispatching module(LC12 S) as the signal transmission unit, which can realize the information collection of the patients and unified management. When the infusion will be over, the alarm signal is transmitted wirelessly to the nurse station. The hospital central control system will realize sound and light alarm according to the test results, and display the specific alarm position for those hospital with lower condition;for the hospital with best condition, every working nurse could equip with an alarm bracelet which can display and alarm need to change droplet bed ID. This system can reduce the medical negligence and improve the efficiency of health care.
