Abstract
In order to solve the existing problems of artificial monitoring transfusion treatment and enhance the automation level of the hospital care and management, a hospital infusion monitoring system is designed. Hospital infusion monitoring system adopts the structure of distributed computer control system, adopts RS485 bus to realize the communication between the upper computer and the lower computer. The lower computer uses MSP430F149 MCU as the core, implements the dripping speed detection, the drug liquid remaining amount detection, at the same time to adjust dripping speed by controlling the stepper motor. PC microcomputer as the monitoring center, accepts data that transmits from the lower computer, and displays, storages, analysises and statistics, at the same time controls the lower computer.
