Abstract
A low cost, easy to use, snap-on, linear-to-vernier syringe by which a volume of material may be controllably and accurately delivered to a recipient. By virtue of the present invention, a piston supporting collar member may be securely snapped into releaseable engagement with a conventional, disposable syringe cylinder to complete the syringe assembly. Moreover, the conventional syringe cylinder is thereby converted into a precisely accurate pipetting cylinder to control the infusion of highly potent, dosage sensitive, radioactive, or expensive drugs, and the like, without requiring any modification to the cylinder. The syringe assembly is particularly adapted to permit rapid switching between freely rotated and incrementally rotated modes of operation, whereby a predetermined volume of material may be selectively imparted from the syringe cylinder, either continuously or in discrete and precisely calibrated increments.
