1. A method for making a pump for dispensing fluids from a syringe comprising:

  • providing a housing with a pair of generally parallel guide rails;

    mounting a slide and a motor on the generally parallel guide rails so that the motor and the slide move along the pair of generally parallel guide rails;

    placing a rod in mechanical communication with the motor so that rotation of the motor causes the rod to move axially along a parallel path relative to the pair of generally parallel guide rails;

    mounting a syringe holding head having a brake element at an end of the rod for holding a syringe barrel;

    placing a drive rod generally orthogonally to the pair of generally parallel guide rails and placing a drive head at an end of the drive rod;

    said drive head configured to drive a piston rod of a syringe; and

    synchronizing the drive head with the brake element so that when the drive head moves by the drive rod, the brake element moves outwardly away from the housing.
