Abstract
Official abstract text for this publication.
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.
