  • Publication number: 20210259922
    Abstract: A syringe for delivery of a medical liquid to a container has a body with proximal end, a frustoconical distal end, and a cylindrical sidewall extending between the proximal end and the distal end along a longitudinal axis. The syringe includes 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. The nozzle includes a plurality of longitudinal ribs formed on an inner surface of the nozzle. The syringe is designed so that the plurality of longitudinal ribs directs a flow of a medical fluid 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. Syringe and connector assemblies and methods for reducing a number of bubbles formed in a medical fluid during a syringe filling procedure are also described.

  • Patent number: 11007118
    Abstract: A fill adapter for delivery of a medical liquid to a container has a body with a distal end, a proximal end, and a central bore extending between the distal end and the proximal end along a longitudinal axis. The central bore has an angled portion at the proximal end of the body such that a diameter of the central portion increases at the angled portion in a direction from the distal end to the proximal end. The fill adapter further has a flow controller disposed within the central bore at a distal end of the angled portion such that a gap is formed between an outer surface of the flow controller and an inner surface of the central bore. The flow controller is shaped to direct liquid flowing through the central bore to flow through the gap and along the angled portion of the central bore under a Coand? effect.

  • Publication number: 20200171234
    Abstract: A cap for intake and delivery of a fluid from a syringe is described. The cap includes an outer cap assembly comprising a fluid inlet path and a fluid outlet path and an inner cap assembly configured for innertion into a fluid nozzle of the syringe and to provide selective fluid communication between an interior of a syringe and the fluid inlet path or the fluid outlet path. The outer cap assembly is slidable relative to the inner cap assembly between a first filling position, where the interior of the syringe is in fluid communication with the fluid inlet path, and a second delivery position, where the interior of the syringe is in fluid communication with the fluid outlet path. The outer cap may further slide, relative to the inner cap assembly, to a third closed position where the interior of the syringe is fluidly isolated from the fluid inlet path and the fluid outlet path. Syringes including the cap are also described.
