In certain embodiments, a syringe mount of the invention may include a plate, an actuator, and one or more movable members located between the plate and the actuator. Each of the plate and the actuator may have an orifice defined therein, and an imaginary reference axis of the syringe mount may extend through one or both of these orifices. The actuator may be movable relative to the plate in a direction substantially perpendicular to the reference axis. Further, the moveable member(s) may be designed to move (e.g., pivot) toward the reference axis due to movement of the actuator from a first position to a second position and to move (e.g., pivot) away from the reference axis due to movement of the actuator from the second position to the first position.
