自动尿量监测仪的研制

摘要

An automatic urine monitoring system is presented to replace manual operation. The system is composed of the flow sensor, MSP430f149 single chip microcomputer, human-computer interaction module, LCD module, clock module and memory module. The signal of urine volume is captured when the urine flows through the flow sensor and then displayed on the LCD after data processing. The experiment results suggest that the design of the monitor provides a high stability, accurate measurement and good real-time, and meets the demand of the clinical application.%针对目前临床上依赖人工测量尿量的现状，设计了一种自动尿量监测系统。系统由流量传感器、MSP430f149单片机、人机交互模块、液晶模块、时钟模块以及存储模块等组成。尿液经导尿管流过流量传感器时，尿量信号被单片机捕获，经过数据处理，配合时钟模块，将当前时刻的尿量显示在液晶屏上，同时存储数据以供查询。实验证明，本系统工作稳定，测量准确，实时性好，满足临床尿量监测要求。
