Abstract: An automatically controlled medicament delivery system having a hand-held gun-shaped device with a handgrip. The device has an internal motor that is powered by connection to a power source, such as AC current or DC battery, a pair of limit switches that control the delivery of the medicament by limiting movement of a helical gear that moves a fitting in response to being powered by the internal motor, the helical gear transferring rotational motion from the electric motor into linear motion through a coupling attached to the helical gear.

Abstract: An automatically controlled medicament delivery system having a hand-held gun-shaped device with a handgrip, the device of unitary construction. The device has an internal motor that is powered by connection to a power source, such as AC current or DC battery, a pair of limit switches which controls the administration of the medicament or implant by limiting movement of a helical gear that moves a fitting in response to being powered by the internal motor, depressing the trigger on the gun-shaped device initiates the internal motor that powers the helical gear that in turn delivers the medicament to the individual animal. Additionally, the device has indicator lights that signal the operator when the injection device is ready to deliver the medicament, when medicament is being delivered, when medicament has been delivered, and when the helical gear is being returned to the original position readying the injection device for the next delivery of medicament.
