ABSTRACT:
The present invention relates to a turbulence minimization apparatus comprising a float and seat assembly adapted to control turbulence and formation of microbubbles in a quantity of contrast media in the burette of a contrast media delivery system. The float includes an upper convex surface providing an impact surface for droplets of contrast media which fall from the inlet of the burette, a lower convex surface for sealing a drainage bore when the volume of contrast media has been substantially drained from the burette, and a predetermined amount of buoyancy. The seat assembly includes a plurality of fluid passageways that allow contrast media to contact the lower convex surface of the float allowing the buoyancy of the float to separate the float from the drainage bore when there is more than a predetermined amount of fluid in the drip chamber.
