Abstract

A system and method for automatically aligning the threads of a lead screw with the threads of a screw drive mechanism, the screw drive mechanism operating to translate the rotational motion of the lead screw into linear motion to expel the contents of a mounted syringe. The system comprises a driver position sensor for determining the position of the screw drive mechanism along the lead screw and a processor for receiving position signals from the driver position sensor, for determining a requisite rotation of the lead screw to ensure alignment of the two sets of threads, and for effectuating the requisite rotation of the lead screw to achieve that alignment. An automatic calibration routine is included that checks for variances in calibration of the system and if found, updates a conversion factor to restore accuracy. Various sensors are used to monitor the operation of components.
