Abstract

A medical fluid valve is provided that includes a housing having an inlet and outlet, a septum located at the inlet, and an arm connected to the housing. The arm can also include a plurality of teeth. When the housing is in a non-accessed position, the plurality of teeth can be positioned to prevent inadvertent access to a container. Furthermore, when the housing is in an accessed position, the plurality of teeth can prevent disconnection.

Claims

1. A medical fluid valve for a container comprising:

a housing including an inlet and an outlet;

a luer accessible valve positioned at the inlet; and

an arm connected to the housing, the arm including a plurality of teeth, the teeth positioned on the arm so as to (i) prevent inadvertent access to the container when the housing is positioned in a non-accessed position with respect to the container and (ii) prevent disconnection after the housing is positioned in an accessed position with respect to the container.

2. The medical fluid valve of claim 1, the valve is configured to receive a male luer.

3. The medical fluid valve of claim 1, the housing including an outlet configured to access a container.

4. The medical fluid valve of claim 1, which includes a gasket positioned on the housing, the gasket sized to seal with a port located on the container.

5. The medical fluid valve of claim 1, the housing including a flange and an arm extending from the flange.

6. The medical fluid valve of claim 1, wherein at least one of the teeth is barbed to prevent the housing from being pulled away from the container after the tooth is forced through an aperture of a port fixed to the container.

7. The medical fluid valve of claim 1, the teeth including a first tooth configured to at least partially hold the housing at the non-accessed position and a second tooth configured to hold at least partially the housing at the accessed position.

8. The medical fluid valve of claim 1, the teeth including a first tooth configured to operate with a frangible tab connected to the arm to hold the housing at the non-accessed position and a second tooth configured to operate with a flange connected to the area to hold the housing at the accessed position.

9. The medical fluid valve of claim 1, the housing including a tube separating the inlet and the outlet, the arm extending generally parallel to the tube.

10. The medical fluid valve of claim 1, the inlet including at least one of:

a removable film covering the inlet; and

a threaded cap.

11. The medical fluid valve of claim 1, which includes a frangible tab removable to allow the housing to be moved from the non-accessed position to the accessed position.

12. The medical fluid valve of claim 1, the arm extending so as to reach a port located on the container but terminating prior to the outlet accessing the container.

13. The medical fluid valve of claim 1, the teeth including a tooth positioned to mate with an opposing tooth of a port located on the container to hold the housing at the accessed position.

14. A medical fluid assembly comprising:

a container;

a port connected to the container; and

a valve including a housing, an arm connected to the housing, the arm including a first tooth configured to at least partially hold the housing in a non-accessed position with respect to the container and a second tooth configured to at least partially hold the housing at an accessed position with respect to the container.

15. The medical fluid assembly of claim 14, the first tooth configured to operate with a frangible tab connected to the arm to hold the housing at the non-accessed position and the second tooth configured to operate with a flange connected to the area to hold the housing at the accessed position.

16. The medical fluid assembly of claim 14, the valve including a first flange, the port including a second flange, the first and second flanges positioned to mate when the housing is located at the accessed position.

17. The medical fluid assembly of claim 14, the port including a flange extending from the port, the flange defining an aperture, the aperture positioned to receive the arm.

18. The medical fluid assembly of claim 17, the port including a port arm extending between the flange and the container to support the flange.

19. A method for accessing a fluid container, the method comprising:

locking a valve in a non-accessed position with respect to the fluid container such that the valve cannot be pulled away from the container;

translating the valve from the non-accessed position to an accessed position; and

locking the valve in the accessed position with respect to the fluid container such that the valve cannot be removed from the container or further translated in the accessed direction.

20. The method of claim 19, which includes maintaining a seal between the valve and the container in non-accessed and accessed positions.

21. The method of claim 20, which includes maintaining a sterile environment between the valve and the container in non-accessed and accessed positions.

22. The method of claim 19, which includes removing a frangible tab from the valve before translating the valve from the non-accessed position to an accessed position.

23. The method of claim 19, which includes inserting a male luer into the valve and withdrawing or injecting fluid.
