电子内窥镜负压自动控制系统的研究

摘要

目的 研制电子内窥镜负压自动控制系统,以改变目前国内电子内窥镜负压系统人工控制方式,使其随电子内窥镜的工作状态自动运行.方法 以视频信号和负压传感器压力信号作为自动控制电路的取样信号,利用自动控制电路电子开关代替负压系统的手动控制开关.结果 简化了电子内窥镜系统的操作手续、提高了工作效率,减少了能源消耗、延长了机器使用寿命.结论 电子内窥镜负压自动控制系统具有性能稳定、安装方便、通用性强的特点,可在国内各级医院不同品牌、不同型号的电子内窥镜上得到广泛应用.%Objective The work presented here was to research into a kind of automatic control system that would be automatically linked to the working status of electronic endoscope. Methods The image video output signal and signal of negative pressure sensor were used to be a sampling signal of automatic control circuit. An electronic switch of automatic control circuit was challenged the manual control device of the negative pressure system. Results This system simplifies the operation procedures;enhances work efficiency reduces energy consumption and improves the service life of the machine. Conclusion The paper concludes that this negative pressure automatic control system has many strengths like stable performance;easy installation and strong versatility. It also can be widely applied in different brand and different types of electronic endoscope in China.
