用于医用注射器的驱动推杆
摘要：
一种用于与医用流体注射器使用的驱动推杆(26)可包括中心、纵向参考轴线(24)。第一和第二抓握构件(92)与驱动推杆的柱塞接合端(266)枢转地互连。第一和第二抓握构件的每一个均可绕共用枢转轴线(95)枢转，该共用枢转轴线与参考轴线相交。每个抓握构件都包括远离共用枢转轴线的第一端(102)。在一些实施例中，第一和第二抓握构件在第一位置和第二位置之间可枢转。在第一位置中，抓握构件的第一端间隔开第一距离，而在第二位置，它们间隔开比第一距离大的第二距离。
摘要（英）：

A drive ram (26) for use with a medical fluid injector may include a central, longitudinal reference axis (24). First and second gripper members (92) may be pivotally interconnected with a plunger engaging end (266) of the drive ram. Each of the first and second gripper members may be pivotable about a common pivot.axis (95) that intersects the reference axis. Each of the gripper members may further include a first end (102) that is remote from the common pivot axis. In some embodiments, the first and second gripper members may be pivotable between a first position and a second position. In the first position, the first ends of the gripper members may be spaced apart.by a first distance, while in the second position, they may be spaced apart by a second distance that is greater than the first distance.
