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 for connecting to an injection port of the infusion fluid container, the connection portion defining a first connection portion fluid channel and a second connection portion fluid channel; a first port positioned at a first port end, the first port defining a first port fluid channel in fluid communication with the first connection portion fluid channel, the first port configured to be connected to a syringe adapter; and a second port positioned at a second port end, the second port defining a second port fluid channel in fluid communication with the second connection portion fluid channel, the second port configured to be connected to intravenous tubing, wherein the connection portion includes a retaining ring extending radially outward from the connection portion and extending around a circumference of the connection portion, the retaining ring is configured to provide a wedging action with the injection port of the infusion fluid container while maintaining a leak-proof seal, wherein the retaining ring has a first side with a tapered, rounded surface, a second side positioned opposite the first side, and a cylindrical surface positioned between the first and second sides, and wherein the second side of the retaining ring defines an 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.

2 . The infusion adapter of claim 1 , wherein the connection portion defines a puncturing point and a main body of the infusion adapter defines a stop, and wherein the retaining ring is positioned closer to the stop than the puncturing point.

3 . The infusion adapter of claim 2 , wherein a space is defined between the stop and the retaining ring.

4 . The infusion adapter of claim 1 , wherein the second side of the retaining ring is planar.
