Abstract
The present invention provides an animal carcass injection system that is particularly suitable for injecting carbon dioxide between muscle and bone within an animal carcass to balloon the muscle away from the bone. Such ballooning aids in boning the animal carcass. In accordance with the present invention, a hollow needle is provided having a pointed distal end to puncture the animal carcass and at least one, but preferably four, circumferentially spaced apertures to allow the pressurized gas to escape from the needle upon blockage of the pointed distal end. The aperture(s) act to prevent possible injury arising from an accidental escape of pressurized gas from the pointed distal end of the needle near or against operators of the injection system. The use of four apertures act to more efficiently distribute gas within the animal carcass upon injection of the pressurized gas.
