The intelligent regulated blood glucose/blood pressure based intravenous infusion pump according to claim 1, wherein said controller is further connected to a bubble sensor and an alarm device, said bubble sensor is located downstream of said second pump plate and is used for detecting whether bubbles exist in the fluid in the infusion tube and transmitting the detected bubble signal to said controller, and said controller controls said alarm device to give an alarm when receiving the bubble signal.
7. The intelligent blood glucose/blood pressure based regulated intravenous infusion pump of claim 1, wherein said controller determines fluid flow data of an infusion tube based on detected blood glucose, blood pressure and/or blood ketone body data of a human body, converts said fluid flow data of said infusion tube into motor operating parameters, and controls said motor drive mechanism based on said motor operating parameters.
