摘要：
A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engagable with the piston regardless of a rotational orientation of the piston relative to the plunger.在此揭露一種用於與注射器一起使用的柱塞，該柱塞具有柱塞主體，該柱塞主體具有近端、遠端、以及在該近端與該遠端之間沿著柱塞縱軸線延伸的周向側壁。該柱塞進一步具有至少一個彈性可偏轉保持構件，該至少一個彈性可偏轉保持構件具有附接到該柱塞主體上的第一區段和朝向該柱塞主體的該遠端凸出並且相對於該第一區段可偏轉的第二區段。該柱塞進一步具有與該至少一個彈性可偏轉保持構件相關聯的至少一個致動構件。該至少一個致動構件與活塞相互作用以便在該柱塞相對於該活塞旋轉時使該至少一個彈性可偏轉保持構件偏轉。不管該活塞相對於該柱塞的旋轉定向如何，該柱塞與該活塞可接合。
