Abstract
A syringe positioning device is disclosed for enhancing control of fluid flow from a syringe. A disposable unit that includes a syringe and rack mounted on a retaining clip is positionable on a drive unit so that, when so positioned, the piston of the syringe is precisely displaced to deliver medicament from the syringe to a patient. A non-disposable unit is also disclosed onto which a syringe and piston can be positioned so that the device thereafter also provides precise medicament delivery. The longitudinal movement of the rack is effected by rotating the pinion gear that is connected with a pulse-driven, power efficient stepper motor, with the operation of the stepper motor being controlled by a pre-programmed memory unit. A hinged rack is also disclosed, as is a one-way ball drive unit.
