Abstract

A handle assembly (100) for a hand-actuated fluid delivery device (10) is disclosed. The handle assembly (100) includes a first handle member (110) that is mounted on a pivot (126) fixed to a second handle member (120). A locking spring (130) is mounted on this pivot (126). This locking spring (130), together with a corresponding actuator (140), cooperate to selectively provide resistance to movement of a plunger (30) in an aspiration direction in at least certain conditions. Disposing the actuator (140) in a locking position disposes the locking spring (130) in a locking configuration. Sliding friction or sliding friction forces between the locking spring (130) and the pivot (126), with the locking spring (130) being in its locking configuration, provides resistance to movement of the first handle member (110) relative to the second handle member (120) in a manner that would move the plunger (30) in an aspiration direction.
