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.
Claims20
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.
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.

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.
