基于光电技术智能输液监控系统设计

Design of Intelligent Infusion Monitor and Control System Based on Photoelectric Technology

目前,中小型医院在进行输液治疗时,都是采用人工调整滴速,这种方式不够准确和方便,并且输液异常、结束时也不易被及时发现,这些因素都会造成医疗事故的发生,而通过布设线缆实现滴液监控耗费人力物力。针对这一问题,基于光电技术、单片机技术、无线通信技术等研究设计了一套分布式智能输液监控系统,采用光电调制解调技术实现液滴速度及滴液高度的测量,单片机实现输液速度计数和显示,通过键盘实时设定点滴速度,并通过控制步进电机控制点滴速度,输液结束时自动报警提示。系统网络通信较好,可有效消除了环境光干扰,具有检测精度高,响应速度快等特点。详细介绍了智能输液现场监控子站软硬件设计。

At present, in middle and small hospital, infusion treatment usually adopts artificial adjustment to control drop speed. This style has inadequate accuracy and convenient, and infusion abnormal and end is difficulty to find, which can cause medical malpractice. In addition, human and material resources are consumed by laying wire cable. Aim to this problem, we design a set of distributed intelligent infusion monitor system based on photoelectric technology, single chip microprocessor, and wireless communica- tion technology, etc. The system completes drop speed and drop height measurement by using photoelectric, modulation and demodulation technology, single chip microprocessor is used to infusion speed count and display. Infusion speed is set by keyboard, and controlled by stepping motor. Alarming device is start when infusion is end. Experiment shows that system network communication is well, environment light interference is effective eliminated, monitor precision is high, response speed is fast. Intelligent infusion area monitor substation design in detail is introduced.
