A design of intelligent transfusion monitoring system based on the DSP and fuzzy control algorithm

Aiming at resolving the defects of manual monitoring during the clinical transfusion process presently, this paper designs an intelligent transfusion monitoring system which uses TMS320F28335 as the microcontroller core. This system is a master-slave distributed architecture. The master station at the health care room can remotely monitor the transfusion process with the help of the application that operates on PC, whereas the slave station, a DSP embedded system, uses a miniature peristaltic pump driven by stepper motor to control the transfusion speed based on the fuzzy control algorithm. The master station can communicate with slave stations with wireless modules through the serial port, so nurses can timely monitor the transfusion process. The experimental results show that this system has advantages such as high accuracy of speed adjustment, quick response and low steady-state error. Because of the good performance and low cost, this system can be widely used in clinical transfusion and pharmaceutical composition analysis occasions.
