摘要：
A rolling diaphragm syringe includes a proximal end having an end wall for engagement with a piston, a distal end having an open-ended discharge neck, a sidewall extending between the proximal end and the distal end along a longitudinal axis, and a piston engagement portion protruding proximally from a central portion of the end wall and configured for engagement with a piston of a fluid injector. The piston engagement portion has a stem with a first end attached to the end wall, a second end extending proximally from the first end, and at least one protrusion that protrudes radially outward relative to the second end. The sidewall is flexible and rolls upon itself when acted upon by the piston such that an outer surface of the sidewall is folded in a radially inward direction as the piston is advanced from the proximal end to the distal end. The outer surface of the sidewall is unfolded in a radially outward direction as the piston is retracted from the distal end to the proximal end.一種滾動膜片注射器，包括具有用於與活塞接合的端壁的近端、具有末端開放的排放頸的遠端、在近端與遠端之間沿著縱向軸線延伸的側壁、以及從端壁的中心部向近端突出並被配置成與流體注入器的活塞接合的活塞接合部。該活塞接合部具有一桿，該桿具有附接至該端壁的第一端、從第一端向近端延伸的第二端、以及相對於該第二端徑向向外突出的至少一個突起。該側壁係柔性的，並且在活塞作用下其自身捲起，使得當活塞從近端向遠端前行時，該側壁的外表面在徑向向內的方向上折疊。在該活塞從遠端向近端回撤時，該側壁在徑向向外的方向上展開。
