Abstract
A syringe drive device 11 includes a fixing section 15 fixing an outer tube 14, a movable holder 16 holding a plunger 13, and a drive section 42 driving the holder 16 along an axis of the plunger to push and pull the plunger with respect to the outer tube 14. An internal pressure detector 18 has a positive pressure detection switch 63 detecting an internal pressure of a syringe 12. A determination section 41 determines the issuance of an alert when the holder 16 is stopped and the positive pressure detection switch 63 is ON. A display section 19 is lit to indicate the alert when the determination section 41 determines to issue the alert.
