Abstract

An improved syringe has a cylindrical barrel having a longitudinal axis, and having a rear end and a front end, the barrel having a rear opening at the rear end, and a front opening, through which a liquid may be dispensed from the interior of the barrel, at the front end; a plunger for axial movement within the barrel, and having a front end for insertion into the barrel through the rear opening thereof, and for pressurizing liquid confined in the barrel between the front end of the plunger and the front end of the barrel, thereby to cause dispensing of the liquid through the second opening, the plunger also having a rear end; and dosing apparatus, disposed between the rear end of the barrel and the plunger; wherein the dosing apparatus includes indexing apparatus defining a plurality of predetermined indexing positions at each of which axial travel of the plunger within the barrel toward the second end thereof is limited to a predetermined depth, each the depth at each the indexing position corresponding to a predetermined volume of liquid confined between the front end of the plunger and the front end of the barrel; and dosage selection apparatus for selectably engaging any of the predetermined indexing positions corresponding to a selected dosage, and for permitting filling of the barrel with the selected dosage only.
