Claim:
1. A flow mixing device configured for use within a fluid path between a fluid injector in fluid communication with a first injection fluid and a second injection fluid and a fluid line connected to a patient for injecting a mixture of the first injection fluid and the second injection fluid into the patient, the flow mixing device comprising: a housing having a proximal end opposite a distal end along a longitudinal axis, and a first portion at the distal end and a second portion at the proximal end, the first portion and the second portion joined together at a seam extending around an outer perimeter of the housing about the longitudinal axis; a first fluid port extending through the second portion and configured for receiving the first injection fluid from the fluid injector and a second fluid port extending through the second portion and configured for receiving the second injection fluid from the fluid injector, the first fluid port and the second fluid port being substantially parallel with the longitudinal axis and radially offset relative to the longitudinal axis; a mixing chamber disposed within the first portion between the proximal and distal ends, the mixing chamber being in fluid communication with the first and second fluid ports for mixing the first and second injection fluids; a third fluid port extending through the first portion at the distal end and in fluid communication with the mixing chamber for discharging the mixture of the first and second injection fluids to the fluid line; and a turbulent flow inducing member disposed within the mixing chamber for promoting turbulent mixing of the first and second injection fluids, wherein the seam has a radial collar surrounding a base surface on one of the first portion and the second portion, and a flange on the other of the first portion and the second portion such that the flange is received within the radial collar, and wherein the second portion encloses an open end of the first portion at the seam.
