Abstract
An enteral dosing control coupling for engagement with an ENFit connector. The enteral dosing coupling includes a cylindrical collar defining a hollow internal chamber and a lumen extension tip projecting axially into the internal chamber and defining an internal lumen extending axially therethrough. The lumen extension tip is a separate piece and configured for coupling engagement with the cylindrical collar such that direct engagement with the lumen extension tip by a non-ENFit connector with required force causes retraction of the lumen extension tip.

An enteral dosing control coupling for engagement with an ENFit connector, the enteral dosing coupling comprising:
- a cylindrical collar defining a hollow internal chamber;
- and
- a lumen extension tip projecting axially into the internal chamber and defining an internal lumen extending axially therethrough,
- wherein the lumen extension tip is a separate piece and configured for coupling engagement with the cylindrical collar such that direct engagement with the lumen extension tip by a non-ENFit connector with required force causes retraction of the lumen extension tip.
An enteral syringe comprising:
- a hollow cylindrical barrel;
- and
- an enteral dosing control coupling comprising:
- a cylindrical collar defining a hollow internal chamber;
- and
- a lumen extension tip projecting axially from the hollow cylindrical barrel into the hollow internal chamber of the cylindrical collar, the lumen extension tip defining an internal lumen extending axially therethrough,
- wherein the lumen extension tip is a separate piece and configured for coupling engagement with the cylindrical collar such that direct engagement with the lumen extension tip by a non-ENFit connector with required force causes retraction of the lumen extension tip into the hollow cylindrical barrel.
