    • A piston adapter, which can be easily removed even when it is mounted on a piston member of a rodless syringe and pressed in a cylinder member, is provided. In piston adapter 200, when manual operation member 230 is manually rotated relative to adapter rod 210, adapter shaft 220 is also rotated to turn the trailing end of flange engagement member 240 engaging with an engagement open/close mechanism near leading end of the flange engagement member, thereby piston adapter 200 can be easily put on and removed from the piston member of the rodless syringe its leading end by manually operating the trailing end of piston adapter 200.
    • 提供一种活塞适配器,其即使在安装在无杆式注射器的活塞构件上并被压在气缸构件中时也能够容易地移除。 在活塞适配器200中,当手动操作构件230相对于接头杆210手动旋转时,适配器轴220也旋转以使凸缘接合构件240的后端与接合开/闭机构接合,使其接近凸缘接合的前端 因此活塞适配器200可以通过手动操作活塞适配器200的尾端而容易地从无杆注射器的活塞件前端引出和移除。
