SYRINGE FILLING ADAPTER Russian patent published in 2020 - IPC A61J1/20 

FIELD: adapters for medical containers.

SUBSTANCE: filling adapter for feeding medical fluid into a container comprises: a body having a distal end, a proximal end and a central channel, extending between distal end and proximal end along longitudinal axis, central channel has divergent part on proximal end of body, so that diameter of central part increases in divergent part in direction from distal end to proximal end; and a flow regulator located inside the central channel at the distal end of the divergent portion to form a gap between the outer surface of the flow regulator and the inner surface of the central channel. Part of the flow regulator is connected to the central channel inner surface by one or more spokes having a first end, connected to inner surface of central channel, and second end connected to flow regulator; and the flow regulator shape is configured to direct liquid flowing through the central channel into the gap and along the divergent part of the central channel according to the Coanda effect. Also disclosed are versions of fluid delivery units.

EFFECT: group of inventions provides simple and fast connection and disconnection of fluid delivery elements.
