PROBLEM TO BE SOLVED: To improve transfusion accuracy by precisely controlling the rotating speed of a motor based on a temperature change and a set flow rate by correcting the rotating speed of the motor based on signals from a temperature detecting means and a flow rate setting means while connecting the motor to both the respective means or any one of them. SOLUTION: A temperature sensor (temperature detecting part) 95 for detecting the ambient temperature mainly as the operating temperature of a transfusion tube is built in a transfusion pump away from the transfusion tube for a prescribed distance and performs motor control correction by reporting the detected temperature to a temperature detecting circuit 238 connected to a central control part 201. When the transfusion pump is activated, a program is started, the set flow rate setting value is confirmed and based on correction values inverting correction values based on the measured result among the characteristic values of a graph stepwisely stored in an EEPROM 213, the correction values are respectively selected. Then, the selected correction values are inputted to a program for driving a stepping motor so that the rotation of the motor ca be corrected. |
