SYRINGE DRIVE DEVICE

摘要

A syringe drive device (1) is provided with a cylinder holding section (3) which removably holds a cylinder (201), a piston operation section (4) which is removably connected to the piston, and a piston drive section (5) which includes racks (31A, 31B) connected to the piston operation section (4) and moves the piston (202) in the push-in direction and the pull-out direction by moving the piston operation section (4). A cylinder (200A) having a certain capacity (for example, 50 cc) is directly mounted to the syringe drive device (1) without using an adapter, but a syringe (200C) having a different capacity (for example, 20 cc) is mounted to the syringe drive device (1) using a cylinder adapter (81) and a piston adapter (82).
