[Problem] Provided is a syringe pump which can discontinue delivery of a drug while preventing the drug from abruptly flowing inside a tube if an occlusion state of the tube is cancelled by straightening bending or twisting of the tube, and thus, the safety of an operation of delivering a drug can be enhanced. [Means for Resolution] A syringe pump 1 includes a drive motor 133; a syringe plunger pressuring member 10 that grasps a syringe plunger 202 of a syringe 200 and presses the syringe plunger 202 in accordance with a clockwise rotation operation of the drive motor 133 so as to deliver a drug inside the syringe 200 to a patient P; a pressure sensor 900 that detects pressure while pressing the syringe plunger 202, in order to detect that a tube 203 is in an occlusion state; and a control unit 100 that performs a counterclockwise rotation operation of the drive motor 133 when pressure detected by the pressure sensor 900 exceeds a predetermined occlusion judgment standard value LC, and stops the counterclockwise rotation operation of the drive motor 133 if any one of the predetermined conditions is fulfilled. |
