Design of intravenous infusion monitoring and alarm system based on wireless communication technology

An intravenous infusion monitoring and alarm system based on wireless transmission technology is presented. And it can real-time monitor infusion process. Alarm signal is given when the infusion is blocked or at the end of the infusion, which will solve the inconvenience of clinical intravenous infusion, and increase the security and efficiency. In this system, the photoelectric sensor technology and signal processing technology are applied to acquire the reliable detection of the infusion drops signal. And Single Chip Microcomputer (SCM) and digital display technology are used to count, display and monitor the quantity and velocity of the liquid, and alarm when there has no liquid or a block. Using wireless communication technology to realize information network and infusion status of every ward are real-time monitored in nurse station. Experimental results show that the system meet the design requirements and is safe and reliable.
