基于无线蓝牙的静脉输液监控器的设计

Design of intravenous infusion monitor based on wireless bluetooth

为了避免传统人工输液系统人力物力耗费大、控制精度低、安全度较低等原因造成的风险,设计了一种基于无线蓝牙的静脉输液监控系统。通过ATmega32L精确检测与控制输液滴速,在输液即将结束,进行预报警;App端设计护士监控管理软件,能够利用蓝牙与下位机设备进行远距离信息通信,使医护人员能够实现集中监测与管理患者输液信息。患者输液数据存入单片机内部的EEPROM中,确保掉电后数据不会丢失。通过算法分析及实验测试,该设计可以确保输液在结束前的5min进入报警状态,可以避免静脉输液过程中的风险,达到安全控制的目的。

In order to avoid the risks caused by the traditional artificial infusion system,such as high cost of manpower and material resources,low control accuracy and low security,a monitoring system for intravenous infusion based on wireless Bluetooth is designed.Through ATmega32 L accurate detecting and controlling the infusion droplet speed,we can forecast and alarm when the infusion is about to end.App terminal designs the nurse monitoring and management software,which can communicate with the lower computer equipment by Bluetooth,so that the medical staff can realize centralized monitoring and management of patient infusion information.The patient′s infusion data is stored in EEPROM inside the microcontroller to ensure that the data will not be lost after power failure.Through algorithm analysis and experimental test,the design can ensure that the infusion enters the alarm state 5 min before the end,avoid the risk in the process of intravenous infusion,and achieve the purpose of safety control.
