Abstract
An enteral dosing control coupling comprising a cylindrical collar defining a hollow internal chamber and a lumen extension tip projecting axially into the internal chamber, the lumen extension tip defining an internal lumen extending through the lumen extension tip. In example forms, the lumen extension tip is integrally formed with the cylindrical collar. In other example forms, the lumen extension tip is a separate piece and is removably engageable within the cylindrical collar.
Claims24
An enteral dosing control coupling comprising:
- a cylindrical collar defining
- a hollow internal chamber,
- a smooth interior surface,
- a collar axial length, and
- a collar free end;
- and
- a lumen extension tip projecting axially into the hollow internal chamber and defining an internal lumen extending axially through the lumen extension tip,
- a tip axial length that is shorter than the collar axial length,
- a tip free end recessed below the collar free end, and
- a contained volume of 0.005 milliliters to about 0.03 milliliters.
An enteral syringe comprising:
- a hollow cylindrical barrel including a cylindrical collar defining
- a hollow internal chamber,
- a smooth interior surface,
- a collar free end, and
- a collar axial length,
- the cylindrical collar including external coupling members;
- and
- a dosing control coupling including a lumen extension tip projecting axially into the hollow internal chamber of the cylindrical collar, the lumen extension tip defining
- a tip axial length that is shorter than the collar axial length,
- a tip free end recessed below the collar free end, and
- an internal lumen extending through the lumen extension tip,
- wherein the enteral syringe defines a syringe volume of 0.5 milliliters to 6 milliliters, and
- wherein a contained volume of the lumen extension tip is 0.005 milliliters to 0.03 milliliters.
An enteral fluid delivery device comprising:
- a lumen extension tip defining
- a fluid delivery conduit extending through the lumen extension tip,
- a tip axial length,
- a tip free end, and
- a contained volume of 0.005 milliliters to 0.03 milliliters;
- and
- an outer coupling collar configured to engage a compatible coupling element, the outer coupling collar at least partially surrounding the lumen extension tip and defining
- a smooth interior surface,
- a collar axial length that is longer than the tip axial length, and
- a collar free end,
- wherein the tip free end is recessed below the collar free end.
