ABSTRACT:
The hypodermic syringe for implanting objects in the bodies of birds, fish, animals, and humans consists of a barrel, a canula attached to one end of the barrel, and a plunger that can be moved back and forth within the barrel. A user implants an object by placing the object inside the canula, making an incision with the canula, and then pushing on the plunger thereby causing the object to move from the canula through the incision and into the body. The canula is designed to securely hold an implant object in a fixed position within the canula from the moment of insertion into the canula until the moment of implantation. The canula is also provided with a window that permits a user to observe the presence of an object and, in the case of objects that are electronic identification tags, to read the data stored in a tag with electromagnetic readers. The plunger is intended to provide the user with the same "feel" as a conventional fluid-injection-type hypodermic syringe. The plunger is also equipped with a pressure-release mechanism to avoid the undesirable effects of air pressure build-up in the barrel which may occur when the plunger is operated by a user.
