尿动力监测系统设计与实现

Design and Implementation of Urodynamic Monitoring System

为了评估和诊断患者的下尿路功能障碍,帮助患者进行下尿路康复训练,设计了一种准确可靠的尿动力监测及自动排尿系统。系统实现了基于导尿导管的压力传感器和称重传感器的膀胱压、腹压和尿量的信号采集电路,同时在尿动力监测的软件上实时绘制尿流率、膀胱压和腹压动态波形,并对各信号进行信号处理与分析,通过搭建模拟实验平台验证了系统性能,实验结果表明该系统稳定可靠,测量准确,满足预期的设计目标,为后续工程设计及临床应用提供支撑。

In order to assess and diagnose lower urinary tract dysfunction in patients and help patients with lower urinary tract rehabilitation training,an accurate and reliable urodynamic monitoring and automatic voiding system was designed.The system realizes the signal acquisition circuit of bladder pressure,abdominal pressure and urine volume based on the pressure sensor of urinary catheter and the load sensor.Meanwhile,the dynamic waveforms of urinary flow rate,bladder pressure and abdominal pressure are drawn in real time on the software of urodynamic monitoring.Signal processing and analysis of each signal are carried out,and the system performance is verified by building a simulation experiment.The experimental results show that the system is stable,reliable,accurate and meets the expected design goals,which can provide support for subsequent engineering design and clinical applications.
