a proximal end, a frustoconical distal end, and a cylindrical sidewall extending between the proximal end and the distal end;
a nozzle at a distal portion of the frustoconical distal end of the syringe, the nozzle having a throughbore providing fluid communication between an interior volume of the syringe and a medical connector configured to be connected to the nozzle; and
a plurality of longitudinal ribs formed on an inner surface of the nozzle wherein the plurality of longitudinal ribs extend proximally from the inner surface from the distal end of the nozzle down at least a portion of an inner surface of the frustoconical distal end;
wherein the plurality of longitudinal ribs directs a flow of a medical fluid along the inner surface of the frustoconical distal end and along an interior surface of the cylindrical sidewall of the syringe under a Coanda effect as the syringe is being filled with the medical fluid.
