ABSTRACT:
A fluid dispenser includes a hollow housing having an elongate chamber formed therein. A power supply is located within the chamber of the housing, the power supply being in electrical communication with a motor also located within the chamber of the housing. A switch, accessible from outside the housing, is in electrical communication with the power supply and motor for selectively operating the motor from a non-operable condition to an operable condition. A gear train is driven by a drive shaft of the motor, the gear train being located within the chamber of the housing and having a plurality of gears. At least one of the gears defines a slow speed gear which is rotatable at a relatively slow rate of speed and at least another of the gears defines a fast speed gear which is rotatable at a relatively fast rate of speed. A rack member is selectively engagable with one of the slow and fast speed gears for moving the rack member linearly from a position in which the end portion is spaced from a carpule containing fluid to be dispensed to a position in which the end portion engages a carpule piston so as to effect the dispensing of fluid from the carpule at a controlled rate. Further provided is means for selectively engaging one of the slow and fast speed gears with the teeth of the rack member.
