Abstract

An infusion adapter for connection with an infusion fluid container includes a connection portion configured to engage an injection port of an infusion fluid container, and a port configured to connect to an intravenous line, with the port in fluid communication with the connection portion. The connection portion includes a retaining ring extending radially outward from the connection portion, with the retaining ring configured to securely connect the infusion adapter to the infusion fluid container to substantially prevent disconnection of the infusion adapter from the infusion fluid container once the infusion adapter is connected to the infusion fluid container. The retaining ring includes an indicator configured to provide visualization of insertion of the connection portion into an injection port of an infusion fluid container.

First claim

What is claimed is:

1 . An infusion adapter for connection with an infusion fluid container, the infusion adapter comprising:
a connection portion configured to engage an injection port of an infusion fluid container; and a port configured to connect to an intravenous line, the port in fluid communication with the connection portion, wherein the connection portion includes a retaining ring extending radially outward from the connection portion, the retaining ring is configured to securely connect the infusion adapter to the infusion fluid container to substantially prevent disconnection of the infusion adapter from the infusion fluid container once the infusion adapter is connected to the infusion fluid container, and wherein the retaining ring includes an indicator configured to provide visualization of insertion of the connection portion into an injection port of an infusion fluid container.

2 . The infusion adapter of claim 1 , wherein the indicator is formed from a first material and a remaining portion of the retaining ring is formed from a second material, and wherein the first material is softer than the second material.

3 . The infusion adapter of claim 2 , wherein the first material is an elastomeric material.

4 . The infusion adapter of claim 3 , wherein the first material is a thermoplastic elastomer.

5 . The infusion adapter of claim 1 , wherein the indicator extends further radially outward than a remaining portion of the retaining ring.

6 . The infusion adapter of claim 5 , wherein the retaining ring includes a first side and a second side positioned opposite the first side, and wherein the indicator is annular and positioned between the first side and the second side of the retaining ring.

7 . The infusion adapter of claim 5 , wherein the indicator includes a rounded outer portion.

8 . The infusion adapter of claim 1 , wherein the retaining ring is positioned adjacent to a stop defined by a main body of the infusion adapter.

9 . The infusion adapter of claim 1 , wherein the retaining ring has a first side with a tapered, rounded surface and a second side positioned opposite the first side, the second side of the retaining ring defining a sharp edge that is configured to engage a portion of the infusion fluid container upon an attempt to withdraw the infusion adapter from the infusion fluid container.

10 . The infusion adapter of claim 1 , wherein the retaining ring is crenelated.

11 . The infusion adapter of claim 1 , wherein the connection portion comprises a puncturing point.

12 . The infusion adapter of claim 1 , wherein the indicator is formed via a two-shot molding process.

13 . An infusion adapter for connection with an infusion fluid container, the infusion adapter comprising:
a connection portion configured to engage an injection port of a infusion fluid container; and a port configured to connect with an intravenous line, the port in fluid communication with the connection portion, wherein the connection portion includes a retaining ring extending radially outward from the connection portion, the retaining ring is configured to securely connect the infusion adapter to the infusion fluid container to substantially prevent disconnection of the infusion adapter from the infusion fluid container once the infusion adapter is connected to the infusion fluid container, and wherein the retaining ring defines a plurality of teeth.

14 . The infusion adapter of claim 13 , wherein the teeth are defined and spaced apart from each other via recesses.

15 . The infusion adapter of claim 14 , wherein the plurality of teeth and the recesses are each rectangular in shape.

16 . The infusion adapter of claim 13 , wherein the retaining ring includes a first end and a second end positioned opposite the first end, the recesses extending from the second end to a position intermediate the first end and the second end.

17 . The infusion adapter of claim 13 , wherein the retaining ring is positioned adjacent to a stop defined by a main body of the infusion adapter.

18 . The infusion adapter of claim 13 , wherein the retaining ring has a first side with a tapered, rounded surface and a second side positioned opposite the first side, the second side of the retaining ring defining a sharp edge that is configured to engage a portion of the infusion fluid container upon an attempt to withdraw the infusion adapter from the infusion fluid container.

19 . The infusion adapter of claim 13 , wherein the connection portion comprises a puncturing point.

20 . The infusion adapter of claim 13 , wherein the retaining ring includes an indicator configured to provide visualization of insertion of the connection portion into an injection port of an infusion fluid container.
