Abstract

An ISO 80369-3 compatible coupling having at least one vent, recessed groove, non-cylindrical geometry and/or textured surface formed therewith. According to one example embodiment, a vent can be formed on a male coupling and/or a female coupling. The vent can be in the form of recessed channel. According to one example embodiment, the coupling comprises non-cylindrical geometry such that at least one vent is provided.

First claim

a male coupler comprising a tapering outer surface and a reservoir defined by an open distal end and an inner surface, the inner surface comprising a first section, a transition section, and a second section, wherein the first section is wider than the second section and the transition section is disposed between the first section and the second section, wherein the male coupler is oriented along a connection axis, wherein the male coupler tapering outer surface is configured for removable sealing engagement with an enteral syringe female coupling tapering inner surface along a connection axis, further wherein the male coupler reservoir is configured to receive a volume of air;
wherein the male coupler tapering outer surface comprises at least one vent configured to release an amount of the volume of air present in the male coupling reservoir during engagement between the ISO 80369-3 compatible coupling and the enteral syringe,
wherein the at least one vent comprises a maximum depth from the tapering outer surface at a top end of the at least one vent and a minimum depth at a closed end of the at least one vent, further wherein the at least one vent comprises a tapered transition from the maximum depth to the closed end.

2. The ISO 80369-3 compatible coupling of claim 1 , wherein the male coupler tapering outer surface extends between a base end and a free end, wherein the at least one vent extends along the male coupler tapering outer surface from the free end toward the base end.

3. The ISO 80369-3 compatible coupling of claim 1 , wherein the male coupler tapering outer surface defines a range of diameters between a maximum diameter at a base end and a minimum diameter at a free end, the at least one vent being recessed from the range of diameters of the male coupler tapering outer surface.

4. The ISO 80369-3 compatible coupling of claim 3 , wherein the male coupler tapering outer surface range of diameters corresponds opposingly with the enteral syringe female coupling tapering inner surface, the at least one vent configured to be removed from sealing engagement with the enteral syringe female coupling tapering inner surface.

5. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent extends a distance along the tapering outer surface from a position relative to the connection axis in alignment with the open distal tip to a position relative to the connection axis in alignment with the inner surface transition section.

6. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent comprises two or more vents.

7. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent comprises a surface configured to be removed from engagement with the enteral syringe female coupling tapering inner surface during engagement between the ISO 80369-3 compatible coupling and the enteral syringe.

8. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent comprises a groove recessed from the male coupler tapering outer surface.

9. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent comprises a texturized surface different from the male coupler tapering outer surface.

10. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent extends along a linear path relative to the connection axis.

11. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent extends along a non-linear path relative to the connection axis.

12. The ISO 80369-3 compatible coupling of claim 11 , wherein the at least one vent extends along a helical path around the male coupler tapering outer surface.

13. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent comprises a length relative to the connection axis of between about 1.5 mm and 6.0 mm.

14. The ISO 80369-3 compatible coupling of claim 1 , wherein the at least one vent comprises a width relative to the connection axis of between about 0.125 mm and 5.0 mm.
