    • A piston adapter has a flange holding mechanism mounted on a distal end thereof for releasably holding a piston flange of a piston of a rodless syringe, a manual operating member disposed on a tip end of the piston adapter for being manually operated, and an interlink mechanism for releasing the flange holding mechanism from the piston flange in conjunction with manual operation of the manual operating member. After the piston adapter is mounted on the piston of the rodless syringe and inserted into the cylinder thereof, the flange holding mechanism can be released from the piston in the cylinder by manually operating the manual operating member near the tip end of the piston adapter which is exposed from the cylinder. Even when the piston adapter that is mounted on the piston of the rodless syringe is pressed into the cylinder, the piston adapter can easily be removed from the rodless syringe.
    • 活塞适配器具有安装在其远端上的凸缘保持机构,用于可释放地保持无杆式注射器的活塞的活塞凸缘,设置在活塞适配器的末端用于手动操作的手动操作构件,以及互连机构 用于将手动操作构件的手动操作与活塞法兰一起释放凸缘保持机构。 在活塞适配器安装在无杆注射器的活塞上并插入其圆柱体中之后,通过手动操作活塞适配器的末端附近的手动操作构件,能够将凸缘保持机构从气缸中的活塞释放, 从圆筒露出。 即使将安装在无杆注射器的活塞上的活塞适配器压入气缸中时,也可以容易地从无杆式注射器移除活塞接头。
