A digital dispenser aid device (10) of the type for use with a syringe (12) includes a housing (24). The syringe (12) can be fixedly mounted within a chamber (28) within the housing (24). A body member 54 includes a recessed portion (56) retaining the cap portion (22) of a plunger (20) therein. The body member (54) is moveable for drawing the plunger (20) of the barrel (14) to draw medicant into the barrel (14). A digital readout display is operatively connected to the body member (54) for projecting a digital output quantitating the amount of fluid drawn into the barrel (14) by movement of the plunger (20) axially out from the barrel (14).
