基于远程无线监控的自动输液系统设计

The Design of Automatic Infusion System Based on Remote Wireless Monitoring

为解决传统输液系统中人工医疗成本高,人工操作风险大,操作不确定等问题,设计了一种可以实现远程无线监控以及能够自动插拔穿刺器的输液系统。系统以STM32为主控芯片,外围电路由水滴传感器、水位传感器、温度传感器、语音识别模块以及蓝牙模块组成。该系统能实现插拔瓶塞穿刺器进行自动换液,并实时监测输液过程中剩余的药液瓶数,并且能对液体加温,调整液体的输液流速。用户能通过语音模块控制对应的操作,通过蓝牙模块建立与移动终端之间的通讯提醒医护人员进行干预操作,以及远程监控,方便医护人员对患者输液情况的实时监测和调整。系统能实现自动化的输液换液,监控过程可靠。将复杂的输液过程智能化,代替传统人工。而且经过多次调试结果,将输液管的穿刺器与瓶塞触点偏差角度控制在3°范围以内,自动准确率能达到90%以上。

To solve the problems of high manual medical costs,high manual operation risks,and uncertain operation in traditional infusion systems,an infusion system that can achieve remote wireless monitoring and automatic insertion and extraction of puncture devices is designed.The peripheral circuit of the STM32 main control chip in the system consists of a water droplet sensor,water level sensor,temperature sensor,speech recognition module,and Bluetooth module.The system can achieve automatic liquid change by inserting and removing bottle stoppers,and monitor the remaining number of drug bottles during infusion in real time.It can also heat the liquid and adjust the infusion flow rate.Users can control corresponding operations through the voice module,establish communication with mobile terminals through the Bluetooth module to remind medical staff to intervene,and remotely monitor,facilitating real-time monitoring and adjustment of patient infusion conditions by medical staff.The system can achieve automated infusion replacement and reliable monitoring process.Intelligentize the complex process of infusion instead of traditional manual labor.Moreover,after multiple debugging results,the deviation angle between the puncture device of the infusion tube and the bottle stopper contact point was controlled within a range of 3°,and the automatic accuracy can reach over 90%.
