Abstract

An IV port body defining an IV port includes a valve body configured as a luer fitting, and a movable valve member defining an outer periphery that is uninterrupted within the periphery is disposed in the valve body. The valve member is biased to a first configuration, wherein a passageway for fluid communication is not established through the valve body. Also, the valve member can be moved to a second configuration, wherein fluid communication through the body is permitted.

Claims

1. An IV port, comprising:

an IV container selected from the group of containers consisting of flexible IV bags and rigid IV container;

at least one port body extending from the IV container;

a valve body operably engaged within the port body, the valve body defining a fluid passageway for permitting fluid flow into and out of the IV container, the valve body being configured as a female luer fitting; and

a valve member positioned in the valve body for selectively blocking fluid through the valve body,

the valve member defining an outer periphery that is uninterrupted within the periphery, the valve member being disposed in the valve body and biased to a closed configuration, wherein a passageway for fluid communication is not established through the valve body,

the valve member being movable to an open configuration when a mating component is engaged, wherein two-way fluid communication through the valve body is permitted.

2. The port of claim 1, wherein the port body is configured in the shape referred to as a "Wedge" port.

3. The port of claim 1, wherein the port body is configured in the shape referred to as a "Boat port".

4. The port of claim 1, wherein the port body is configured in the shape referred to as a "Saddle" port.

5. The port of claim 1, wherein the port body is configured in the shape referred to as a "Belly Button" port.

6. The port of claim 1, wherein the port body is configured as a check valve, in which a resilient valve member biased to the first configuration, wherein a passageway for fluid communication is not established through the valve body, the member being deformable to a second configuration, wherein fluid communication through the body is permitted.

7. The port of claim 1, wherein the valve body has a continuous smooth outer surface defining a periphery, the valve body being in contact with the IV container entirely around the periphery to facilitate leak-free engagement between the bag and the valve body.

8. The port of claim 7, wherein the IV container is a bag, and the port further comprises a tube disposed in the bag, the valve body being received in the tube for facilitating leak-free engagement between the bag and the valve body.

9. A port comprising:

a container selected from the group of containers consisting of flexible IV bags and rigid IV containers;

at least one port body extending from the IV container, the port body configured as a wedge port, boat port, or a saddle port;

a valve body operably engaged within the port body, the valve body defining a fluid passageway for permitting fluid flow into and out of the IV container, the valve body being configured as a luer fitting;

a valve member positioned in the valve body for selecting blocking fluid through the valve body, the valve member defining an outer periphery,

the valve member being disposed in the valve body and biased to a closed configuration, wherein a passageway for fluid communication is not established through the valve body, the valve member being movable to an open configuration when the leur is engaged, wherein two-way fluid communication through the valve body is permitted.

10. The port of claim 9 wherein the luer is configured as a female luer.

11. The port of claim 9 wherein the luer is configured as a male luer, with a male valve element disposed in the valve body and defining an engagement surface extending outwardly beyond the valve body for contacting a connector to cause the valve element to move the valve member to an open configuration.

12. A port comprising:

a container selected from the group of containers consisting of flexible IV bags and rigid IV containers;

a valve body defining a port for permitting fluid flow into and out of the IV container, the valve body being configured as a luer fitting;

at least one port body configured as a belly button port;

a valve member positioned in the valve body for selectively blocking fluid flow through the valve body, the valve member defining an outer periphery that is uninterrupted within the periphery, the valve member being disposed in the valve body and biased to a closed configuration, wherein a passageway for fluid communication is not established through the valve body, the valve member being movable to an open configuration when the luer is engaged, wherein two-way fluid communication through the valve body is permitted.

13. A port according to claim 12, wherein the luer is configured as a male luer.
