Abstract
A device for humane injection of fluid into animals from a distance is disclosed. The device comprises a hollow body with a primary chamber suitable for holding the fluid to be injected, a hollow needle at the forward end of the hollow body, a disposable tag attached to the forwardmost surface of the hollow body, and a remote retrieval means. The device may be projected toward the target animal by any of several conventional methods including compressed gas or chemical explosion gun. Upon impact with the target animal a trigger mechanism which comprises a ball and valve seat check valve is tripped allowing a resilient means to force the fluid through the needle and into the animal. The device is held in place during the injection process by an adhesive means on the forwardmost surface of the tag. After injection the device is pulled form the animal using the retrieval means. The tag separates from the device and remains attached to the skin marking the animal.
