Kind Code:
A1
Abstract:
The present invention makes a drug solution injection system more compact. This drug solution injection system has a syringe support assembly 120 for supporting a syringe 20 and a linear actuator 130 which is driven by a motor and causes the reciprocating movement of a plunger 220. The syringe support assembly 120 has a syringe presser 123 and a coil spring 124 which biases the syringe presser 123 to the front. The syringe presser 123 is supported so as to be capable of moving in the front-rear direction, and is designed so as to have a shape and size capable of blocking the opening at the rear end of a syringe outer cylinder 210 while in a state in which the syringe 20 is supported by the syringe support assembly 120.
