Abstract
A movement and control mechanism for operating a syringe is disclosed. The movement mechanism includes a rotatable shaft and two rods disposed coaxially to the shaft and a plunger associated unit. The plunger unit accommodates a plunger of a syringe and axially translates upon rotation of the shaft. An electrical sensor system is implemented with the movement mechanism for detecting the presence of a syringe plunger in the plunger associated unit during the operation of the mechanism. The electrical sensor system forms an interruptible electrical circuit between the rods of the movement mechanism, allowing continuous detection of the presence of a plunger in the plunger associated unit during axial translation of the plunger associated unit along the rods.
