ABSTRACT:
A retrieval system for a range animal injection apparatus is described. The retrieval system includes a valve positioned between a syringe and a needle. In an open position there is a free flow of liquids from a syringe to the needle. In the closed position flow is precluded. A contact member is movable axially in relation to the needle between a first end and a second end. A rigid coupling couples the movement of the contact member and a valve member. The valve is in a closed position when the contact member is positioned adjacent the second end of the needle. The valve is in an open position when the contact member is positioned adjacent the first end of the needle. When the second end of the needle enters a hide of an animal the contact member is pushed toward the first end of the needle by the hide of the animal forcing the valve into the open position. Pressure from a pressure source urges liquid medication in the syringe passed the open valve member through the needle until the liquid medication has vacated the syringe. Continued pressure from the pressure source then urges the valve member into the closed position, thereby moving the contact member toward the second end of the needle until the contact member pushes the needle out of the hide of the animal.
