It was based on the PLC as the control core, PLC control of stepping motor speed, thus the speed control change. PLC control air bubble detection circuit, detection circuit and choke can be used to detect change if there is a perfusion tube obstruction phenomenon in the process, and whether there are air bubbles. The speed automatic control system can change the change, to ensure that patients in the process of change of change rate of stability. To avoid the manual adjustment change speed to body harm to patients.

It is based on the PLC as the control core, PLC stepper motor speed control, and then control the transfusion speed. PLC control bubble detection circuit and detection circuit can be blocked, whether monitoring change in blocking the transfusion tube, as well as to whether there is a bubble. The system can automatically control the transfusion speed change, to ensure that patients in the transfusion process to stabilize exchange transfusion speed. To avoid the manual adjustment of exchange transfusion speed bring harm to the patient's body.
