Abstract

An enteral adapter coupling for connecting non-ENFit threaded enteral equipment with ISO 80369-3 compliant and compatible enteral equipment. The adapter coupling includes a first end substantially corresponding to an ISO 80369-3 coupling format, a second end substantially conforming to a threaded enteral feeding coupling format, and an internal lumen extending through the coupling allowing fluid communication between the first end and the second end.

First claim

What is claimed is:

1. An enteral adaptor coupling comprising:
a first end, a second end, and an internal lumen extending between the first end and the second end allowing fluid communication between the first end and the second end, the first end comprising a threaded portion formed thereon and the second end comprising a threaded portion formed thereon, the first end substantially corresponding to an ISO 80369-3 compliant coupling format, and the second end substantially conforming to a threaded enteral feeding coupling format,
wherein the internal lumen extends along a longitudinal axis, further wherein the internal lumen comprises a first lumen section at the first end having a constant internal diameter, a second lumen section at the second end having a tapered internal diameter, and a third lumen section disposed between the first lumen section and the second lumen section along the longitudinal axis and having a constant internal diameter, wherein the constant internal diameter of the third lumen section is not equal to internal diameter of the first lumen section or any internal diameter of the tapered second lumen section.

2. The enteral adaptor coupling of claim 1 , wherein the first end comprises a male ISO 80369-3 compliant tip having a tapered lead-in portion, surrounded by a coaxial connection collar having an internally threaded annular surface.

3. The enteral adaptor coupling of claim 1 , further comprising a body extension portion provided between the first end and the second end.

4. The enteral adaptor coupling of claim 1 , wherein the thread pitch of the threaded portion of the second end is between about 2 mm to about 3 mm.

5. The enteral adaptor coupling of claim 1 , wherein the threaded portion of the second end is defined on an exterior portion thereof.

6. The enteral adaptor coupling of claim 5 , wherein the outer tip diameter is about 6.675 mm.

7. The enteral adaptor coupling of claim 1 , wherein the second end comprises a tip geometry having a tip length of between 8 mm to 11 mm.

8. The enteral adaptor of claim 7 , wherein the tip length is about 9.687 mm.

9. The enteral adaptor coupling of claim 1 , wherein the first end comprises a female ISO 80369-3 compliant tip having at least a pair of helically inclined ribs extending radially from the external face of the tip.

10. The enteral adaptor coupling of claim 9 , wherein the second end comprises a male tip having a tapered lead-in portion, and being surrounded by a coaxial connection collar having an internally threaded annular surface comprising a thread pitch of between about 2 mm to about 3 mm.

11. The enteral adaptor coupling of claim 9 , further comprising a lumen extension tip projecting axially from within the female ISO 80369-3 compliant tip in a direction generally opposite the second end, and defining the internal lumen extending therethrough.

12. The enteral adaptor coupling of claim 2 , wherein the second end comprises a male tip having a tapered lead-in portion, and being surrounded by a coaxial connection collar having an internally threaded annular surface comprising a thread pitch of between about 2 mm to about 3 mm.

13. The enteral adaptor coupling of claim 12 , wherein the first and second ends are configured for coupling two syringes together to facilitate the transfer of fluids therebetween, wherein one of the syringes comprises a female ISO 80369-3 compliant tip for engagement with the first end of the coupling and wherein the other one of the two syringes comprises a cylindrical connection tip substantially conforming to the threaded enteral feeding coupling format for engagement with the second end of the coupling.

14. A threaded enteral feeding coupling comprising:
a first end formed at the end of a syringe or removably coupled thereto, the first end comprising an ISO 80369-3 compliant coupling format;
a second end comprising a non-ISO 80369-3 compatible cylindrical connection tip; and
a lumen extending through the coupling from the first end to the second end,
wherein the internal lumen extends along a longitudinal axis, further wherein the internal lumen comprises a first lumen section at the first end having a constant internal diameter, a second lumen section at the second end having a tapered internal diameter, and a third lumen section disposed between the first lumen section and the second lumen section along the longitudinal axis and having a constant internal diameter, wherein the constant internal diameter of the third lumen section is not equal to the internal diameter of the first lumen section or any internal diameter of the tapered second lumen section.

15. The threaded enteral feeding coupling of claim 14 , further comprising a body extension portion provided between the first end and the second end.

16. The threaded enteral feeding coupling of claim 14 , further comprising a lumen extension tip projecting axially from within the cylindrical connection tip, the lumen extension tip being configured for fitting within an internal lumen of a male tip having a tapered lead-in portion, and being surrounded by a coaxial connection collar having an internally threaded annular surface comprising a coupling format that mates with and connects to the external threads of the cylindrical connection tip.

17. A method of coupling enteral connectors of different coupling formats together comprising:
providing a coupler comprising a first end and a second end, the first end substantially corresponding to an ISO 80369-3 compliant coupling format and the second end substantially conforming to a threaded enteral feeding coupling format, and an internal lumen extending through the coupling allowing fluid communication between the first end and the second end, wherein the internal lumen extends along a longitudinal axis, further wherein the internal lumen comprises a first lumen section at the first end having a constant internal diameter, a second lumen section at the second end having a tapered internal diameter, and a third lumen section disposed between the first lumen section and the second lumen section along the longitudinal axis and having a constant internal diameter, wherein the constant internal diameter of the third lumen section is not equal to the internal diameter of the first lumen section or any internal diameter of the tapered second lumen section;
providing a first connector substantially corresponding to an ISO 80369-3 compliant coupling;
providing a second connector substantially conforming to a threaded enteral feeding coupling format;
coupling the first connector to the first end of the coupling; and
coupling the second connector to the second end of the coupling.

18. The method of claim 17 , further comprising delivery of an enteral fluid through the internal lumen between the first and second ends.

19. The threaded enteral feeding coupling of claim 14 , further comprising a lumen extension tip projecting axially from within the cylindrical connection tip.

20. The enteral adaptor coupling of claim 1 , wherein the internal diameter of the first lumen section is a constant diameter.
