Abstract:
A method of loading a tubular replacement syringe into a power injector for injecting fluid into an animal, the method comprising the steps of:providing a power injector having:a syringe mount adapted to receive a rearward end of a syringe having a generally circular exterior, anda ram having a motor linked thereto and operable to reciprocate the ram along a line extending generally through the mount; andproviding a hollow tubular syringe that includes:a cylindrical body having an axis, a generally circular exterior, a rearward end and a closed forward end with a fluid discharge orifice therein, anda plunger axially slidable in the body and in sealable contact therewith;providing the syringe mount of the injector and the generally circular exterior of the syringe each with mating locking structure fixed thereto and configured to lock the syringe to the mount upon the rotation of the syringe; then:mounting the syringe to the injector by generally rearward axial movement of the syringe toward the injector followed by bodily rotating the syringe, including the cylindrical body thereof on the axis of the body relative to the injector to thereby lock the body of the syringe at the generally circular exterior thereof with the mating locking structure to the mount of the injector; andcoupling the plunger to the ram so that the plunger is capable of being driven forwardly or rearwardly by the ram.
