Syringe fill adapter

A syringe and connector assembly comprising:

• a syringe comprising:
• 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;
• and
• a connector comprising a flow controller disposed within a central bore of the connector,
• wherein the connector connects to a distal end of the nozzle and the central bore provides fluid communication between an interior volume of the syringe and a tubing element, and
• wherein the plurality of longitudinal ribs directs a flow of a medical fluid from a fluid path of the connector along an inner surface of the frustoconical distal end and along an interior surface of the cylindrical sidewall of the syringe under a Coand{hacek over (a)} effect.

A method for reducing a number of bubbles formed in a medical fluid during a syringe filling procedure, the method comprising:

• flowing the medical fluid past a flow controller disposed within a central bore of a nozzle of a syringe;
• diverting the medical fluid by the flow controller in a radially outward direction toward an angled portion of an inner surface of a frustoconical distal end of the syringe;
• flowing the medical fluid down the inner surface of the frustoconical distal end of the syringe;
• flowing the medical fluid down an interior surface of a cylindrical sidewall of the syringe, wherein the sidewall extends between the frustoconical distal end and a proximal end;
• and
• filling an interior volume of the syringe with the medical fluid.
