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.

Abstract: A connector assembly may include a body and a fluid fitting, the fluid fitting configured for releasably engaging a syringe nozzle, at least one deflectable locking arm connected to the body and radially deflectable relative to the distal end, the proximal end of the at least one deflectable locking arm configured for deflecting in a radial direction relative to the distal end to releasably engage the syringe nozzle, and at least one locking element disposed on the at least one deflectable locking arm, the at least one locking element movable with movement of the at least one deflectable locking arm between a first position where the at least one locking element is released from an engagement portion of the syringe nozzle and a second position where the at least one locking element is engaged with the engagement portion of the syringe nozzle.

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 Coandă effect.
