Automatic poultry injection delivery apparatus

The present invention relates to a device for the injection delivery of drugs or vaccines to birds. More particularly, the present invention allows the subcutaneous or intramuscular injection of one or two doses of drugs or vaccines into bird. The present invention provides systems for the injection delivery of at least two fluid doses to a small bird by penetrating the skin of the recipient bird with at least two injection needles. It is then possible to simultaneously inject drugs, or other fluid vaccines that do not mix well or whose mixture would be detrimental to the stability or efficacy of the active ingredients therein. The present invention provides a novel injection needle support for connecting the injection needles to dose distributors and fluid supply containers while maintaining the injection ends of the injection needles in a substantially parallel arrangement.The injection needle support typically is attached to a carrier connected to an actuator, an actuator power source and a switch mechanism wherein the actuator, when activated, can reciprocally move the carrier and injection support toward and away from an injection position. The injection delivery system may further include one or more dose distributors and fluid supply containers for delivering fluid doses to the injection needles for injection into a recipient bird held against an aperture in a retaining plate.
