无线镇痛系统的研制
|
摘要
目的研制一套由镇痛泵泵头、路由基站和远程监控台组成的无线镇痛系统,以缓解术后患者的疼痛。方法镇痛泵泵头终端模块完成麻醉液输注的具体动作,并通过Wi-Fi与远程监控台进行无线数据通信。通过优化系统软件以及模块的电源管理等方面对镇痛泵泵头进行了低功耗软硬件设计;从机械装夹和软件校准等多方面提出了增大泵头精度的方法。基于压力模块和霍尔模块对镇痛泵报警方法进行研究并建立模型,根据不同的算法提取压力信号相应的特征,从而识别出管路堵塞、有气泡、无液和正常工作4种状态。结果通过对研制的无线镇痛系统进行精度和工作时长测试以及管路4种不同工作状态报警分析,可知本系统能够正常工作,压力模块可精确报警。结论本系统的功耗低、精度高,具有精确的报警提示功能,可实现患者自控镇痛。
Objective In order to ease the pain of the postoperative patients,we design a wireless analgesic system,which consists of analgesic pump head,routing base station and remote monitoring platform.Methods The terminal module of analgesic pump head is used to complete the specific operation of the infusion and we can achieve the function of wireless data communication with remote monitoring stations via Wi-Fi. We have low-power hardware and software design by optimizing software and power management of modules. We propose the mothods of increasing the accuracy of the pump head from mechanical clamping, software calibration and other aspects. And we study the alarm method based on pressure module and Hall module of analgesia pump. The model is established and the signal's corresponding features are extracted according to different algorithms to identify the four states of pipeline jam,air bubble,no liquid and normal work. Results Through the development of the wireless analgesia system for precision testing,working hours testing and pipeline alarm analysis of four different working state,we know that the system can work normally and the pressure module can accurately alarm. Conclusions The system is low consumption,high precision,and this system can achieve patient-controlled analgesia.
