Abstract
A method and apparatus for controlling and visually, audibly, and tactilely communicating the administration of discrete unit doses of material dispensed from a dropper through use of a modified plunger having a geometric profile corresponding to a unit dose. This profile engages with the dropper interior in a manner that creates audio, visual, and tactile cues as each unit dose is administered. The profile may take the form of peaks and valleys or teeth. Alternatively, the plunger profile may be threaded and may include a channel along the plunger's longitudinal axis.
