Abstract:
A syringe pump (100) is applied to a syringe (200) that includes a barrel (210) and a plunger rod (220) which is fitted inside the barrel (210). A flange (221) is provided at a rear end of the plunger rod (220). The syringe pump (100) includes a clamping mechanism (150, 160) which clamps and fixes the flange (221) of the plunger rod (220) in the thickness direction of the flange (221). The clamping mechanism (150, 160) includes a pushing portion (150) which includes a pressing face facing a rear end face of the flange (221), and a gripping portion (160) which is movable in the thickness direction and connected to the pushing portion (150) so as to form a gap with the pressing face in the thickness direction, and is configured to work in cooperation with the pushing portion (150) so as to fix the flange (221). The pushing portion (150) includes a locking mechanism (153A, 155A) which locks the movement of the gripping portion (160) in a direction away from the pressing face with the flange (221) being fixed.
