Abstract: A syringe for a fluid delivery system includes a pressure jacket having a distal end, a proximal end, and a throughbore therebetween. The syringe further includes a rolling diaphragm having a proximal end with an end wall for engaging a plunger, a distal end received within the throughbore of the pressure jacket. A sidewall extends between the proximal end and the distal end of the rolling diaphragm along a longitudinal axis. At least a portion of one of the sidewall and the end wall has non-uniform thickness. At least a portion of the sidewall is flexible and rolls upon itself when acted upon by the plunger such that an outer surface of the sidewall at a folding region is folded in a radially inward direction as the plunger is advanced from the proximal end to the distal end of the rolling diaphragm.

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.
