There is provided a device for automatic synchronized injection and aspiration of fluids comprising: a first linear actuator; a second linear actuator; a first coupling mechanism attached at a distal end portion of the first linear actuator, the first coupling mechanism arranged for detachable coupling to a first plunger of a first syringe; a second coupling mechanism attached at a distal end portion of the second linear actuator, the second coupling mechanism arranged for detachable coupling to a second plunger of a second syringe; and a synchronization mechanism mechanically coupled to the first and second linear actuators, the mechanism arranged so that insertion of the first plunger further into a first barrel of the first syringe is synchronized with extraction of the second plunger from a second barrel of the second syringe, thereby injection from the first syringe is synchronized with aspiration into the second syringe.
