摘要

An articulated injector mechanism, inserted into an adjustable passage adjoined to the animal to be vaccinated, is driven by a mechanical or electrical actuator to inject a dose to the animal using hypodermics. The actuator is operated in response to the animal movement, and combined with the injector mechanism to form a reversible portable structure.
