<P>PROBLEM TO BE SOLVED: To provide an infusion pump which can always ensure infusion accuracy in spite of the size of a fixed flow rate or a use environmental temperature, or both even if the flow rate is established arbitrarily from the scope of 0.1-1,200 mL/h. <P>SOLUTION: The infusion pump administers transfusion by making an infusion tube do peristaltic motion. A flow rate setting means to obtain a flow rate setting signal from the flow rate established arbitrarily from the scope of 0.1-1,200 mL/h, a temperature detection means to detect an operative temperature and to obtain a temperature detection signal, and a control means which is connected to the temperature detection means and the flow rate setting means, and controls the drive of the motor based on the correction value which increases almost linearly based on the flow rate setting signal and the temperature detection signal in order to control the drive of the motor are provided. The control means controls the drive of the motor based on an inverted correction value which reverses the correction value when the flow rate setting signal is about 25 mL/h or less or the temperature detection signal is about 25°C or less, or both of them happen. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
