A feeding tube port for use in connection with an enteral feeding system is provided. The feeding tube port includes an inner core made of a first material and an over-layer made of a second material. The over-layer at least partially encloses the inner core, such that the inner core is configured to resist separation from the over-layer. In some aspects, the inner core may be formed from a rigid plastic material and the over-layer may be formed from a pliable material. The inner core may include one or more ribs, slots and/or apertures configured to enhance adherence between the inner core first material and the over-layer second material. The inner core may further include one or more contact points configured for attachment of a feeding tube valve other similar component to the feeding tube port.

- Claim:
1. A feeding tube port for use in connection with an enteral feeding system, the feeding tube port comprising: an inner core made of a first material and an over-layer made of a second material, wherein the over-layer at least partially encloses the inner core, wherein the inner core is configured to resist separation from the over-layer, wherein the inner core comprises: an upper surface, a lower surface, a side surface, and an aperture extending therethrough from the upper surface to the lower surface; one or more openings in the upper surface of the inner core located radially outward from the aperture; a plurality of openings in the lower surface of the inner core located radially outward from the aperture; a first rib extending radially from the side surface of the inner core and circumferentially around the side surface of the inner core and forming a recessed channel extending circumferentially around the inner core between a top surface of the first rib and the upper surface of the inner core.
- Claim:
2. The feeding tube port of claim 1 , wherein the first material is a rigid plastic material.
- Claim:
3. The feeding tube port of claim 1 , wherein the second material is a pliable material.
- Claim:
4. The feeding tube port of claim 1 , wherein the inner core further comprises one or more slots and/or indented portions configured to enhance adherence between the inner core first material and the over-layer second material.
- Claim:
5. The feeding tube port of claim 1 , wherein the feeding tube port comprises an inner lumen extending through the inner core and the over-layer.
- Claim:
6. The feeding tube port of claim 1 , wherein the inner core comprises one or more contact points configured for attachment of a feeding tube component to the feeding tube port.
- Claim:
7. The feeding tube port of claim 6 , wherein the one or more contact points comprises at least one snap, twist, or locking feature for attaching the feeding tube component to the feeding tube.
- Claim:
8. The feeding tube port of claim 1 , wherein the inner core comprises a surface comprising printed or molded text that is configured to be visible through the over-layer.
- Claim:
9. The feeding tube port of claim 1 , wherein the first material is a rigid thermoplastic.
- Claim:
10. The feeding tube port of claim 1 , wherein the second material is a thermoplastic elastomer.
- Claim:
11. The feeding tube port of claim 1 , further comprising a feeding port and a balloon port, wherein the feeding port is formed by the inner core and the over-layer.
- Claim:
12. The feeding tube port of claim 11 , wherein the balloon port is formed by the inner core and the over-layer.
- Claim:
13. The feeding tube port of claim 1 , wherein the inner core is a unitary structure.
- Claim:
14. The feeding tube port of claim 1 , wherein the first material is polycarbonate and the second material is polyurethane.
- Claim:
15. The feeding tube port of claim 1 , wherein the inner core has a generally cylindrical shape.
- Claim:
16. The feeding tube port of claim 15 , wherein the first rib is formed in the cylindrical shape.
- Claim:
17. The feeding tube port of claim 1 , wherein the lower surface of the inner core has one or more cut-out or indented portions.
- Claim:
18. The feeding tube port of claim 17 , wherein the lower surface of the inner core has a maximum diameter D 2 and a diameter D 3 across at least one of the one or more cut-out or indented portions, the diameter D 3 being less than the diameter D 2 .
- Claim:
19. The feeding tube port of claim 1 , wherein the upper surface of the inner core has a maximum diameter D 1 , the lower surface of the inner core has a maximum diameter D 2 , and the diameter D 2 is approximately equal to the diameter D 1 .
- Claim:
20. The feeding tube port of claim 1 , wherein the inner core further comprises: a first shoulder defined between an upper surface of the recessed channel and a first portion of the side surface, the first portion of the side surface extending between the first shoulder and the upper surface of the inner core; a second shoulder defined between a lower surface of the recessed channel and a second portion of the side surface; a second rib extending radially from the side surface of the inner core, the second rib spaced axially from the first rib and located between the first rib and a bottom surface of the inner core; a second recessed channel extending circumferentially around the inner core between a bottom surface of the rib and an upper surface of the second rib.
