Abstract:
A syringe comprising:a syringe barrel having a longitudinal axis and an opening extending longitudinally therethrough, said barrel further having a proximal end and a distal end; a barrel plug positioned at said proximal end of said syringe barrel; a needle plug positioned at said distal end of said syringe barrel and remaining stationary in relation to the syringe barrel; a plunger piston placed within said opening of said barrel and movable longitudinally within said barrel opening between said barrel plug and said needle plug, said plunger piston dividing said barrel opening into an air pressure chamber and a medicine chamber; at least one needle attached to said needle plug, said at least one needle having a passageway enabling flow of medication therethrough, and being aligned with said syringe barrel along said longitudinal axis; a pressure reacting member positioned adjacent said at least one needle, said pressure reacting member enabling said barrel to be movable longitudinally in response to pressure placed on said pressure reacting member from impact with an animal and in response to pressure placed on said pressure reacting member from said plunger piston; wherein said at least one needle is first placed such that said needle plug prevents flow of medication through said at least one needle, and said needle plug being slidable over said needle in response to distal travel of said barrel thereby exposing said passageway and allowing medication to flow through said passageway, and into tissue of an animal.
